"Incentives" for 5 Star Reviews on Ecommerce Sites [denialism blog]

Posted: 29 Jan 2012 03:58 PM PST

In case you missed it, here's a pointer to a recent Times story concerning baked reviews on Amazon and the like. In it, David Streitfeld describes how one company gave rebates to customers in exchange for five star reviews. They even seem to have a claque to address detractors--

Even a few grouches could not spoil the party. "This is an egregious violation of the ratings and review system used by Amazon," a customer named Robert S. Pollock wrote in a review he titled "scam."
He was promptly chastised by another customer. This fellow, himself a seller on Amazon, argued that he had both given and gotten free items in exchange for reviews. "It is not a scam but an incentive," he wrote.

You might recall the hysteria surrounding recent Federal Trade Commission rules on sponsored endorsements by bloggers. The agency had this type of situation in mind--average consumers, without any understanding of the rules or "ethics" of advertising are pimping products to others. It's unfair to competitors and other consumers. And it totally messes up my default shopping strategy of just buying the highest rated [insert product here] on Amazon!

Thanks, CWRU, for forcing me to get the paper bag out again [Respectful Insolence]

Posted: 30 Jan 2012 12:00 AM PST

It's rare that I have much in the way of reluctance to leap into writing about a topic. Any regular reader of this blog should know this to be true, given the topics I regularly take on and how often my writing draws flak my way from various proponents of quackery and pseudoscience, in particular the antivaccine crowd. Still, sometimes a topic gives me pause, although, I must admit, the reason is that blogging about it will bring embarrassment to me. Usually, I can overcome this reluctance, as I have done in discussing, for example, how my alma mater, the university from which I obtained both my undergraduate and graduate degree, has an actual program in magic (i.e., anthroposophic medicine). Then there was the example of how reiki had infiltrated my old stomping grounds at MetroHealth Medical Center, one of the hospitals at Case Western Reserve University where I rotated during my general surgery residency. Then, just last week, there was the most embarrassing fact that I had to acknowledge, namely that the cancer center at Case has gone woo, even going so far as to host the 2011 meeting of the Society of Integrative Oncology.

So what more could embarrass me? One more thing, it would appear, so much so that it's time to get the paper bag out again; you know, the one I routinely used to get out when surgeons and other physicians spouted embarrassing things back in the day.

I had heard about this a couple of days before P.Z. Myers blogged about it, but had decided that I probably wasn't the one to blog about it. Then, P.Z. had to go and rub my face in the embarrassment of it all by writing about a paper published by a faculty member at the Case Western Reserve University School of Medicine named Erik Andrulis. He was, I have to admit, depressingly spot-on in pointing out that a comparison to jabberwocky is inevitable. I, however, have another comparison that I think more apt, as you will soon see. First, though, I must admit that I found it very surprising that someone like Andrulis would publish a paper like this. If you look at his publication list, with one glaring exception, it looks pretty respectable. Basically, he studies enzymes that metabolize RNA called RNases:

Islamic science has come to this pitiful end [Pharyngula]

Posted: 29 Jan 2012 01:56 PM PST

The words of the Prophet Muhammad (sallallahu 'aleihi was-sallam) have been tested scientifically, and found hilarious. In work carried out under the direction of Dr. Jamaal Haamid, students at Qassim University examined a saying by the prophet, and have published it in a freely available pdf, The Hadeeth on the Fly, which you can download if you desire. Or you could just read this post, which summarizes entirely the complete content of the short paper, which is pretty much unpublishable and unbelievable anyway.

Here are the holy words.

(Notice that I include the original Arabic so there can be no confusion!)

If a housefly falls in the drink of anyone of you, he should dip it (in the drink), for the one of its wings has a disease and the other has the cure of the disease.

I do find that rather disturbing: so in Arabia, if a fly touches your water, you're supposed to catch it, dunk it in deeper and slosh it around, to prevent disease? Arabian flies buzz around with pathogens segregated to just one wing, while the other one is healthy? How do they do that?

OK, setting aside the sanitary habits of Arabians and the mechanism by which this holy aphorism could be true, our intrepid students do carry out the obvious experiment: they drop a fly in a flask of sterile water, and then they pluck out the fly and immerse it completely in a second flask of sterile water. But then it all goes horribly wrong.

Here is the result of experiment #1.

Plate 2- Cultured water sample taken from a flask containing sterilized water and where a fly fell (without submersion). Growth of pathogenic (disease causing) bacterial colonies of the E. coli type were identified after taking samples from the water in the flask for culture.
Plate 1- Cultured water sample from the same flask following the complete dipping of the fly. An entire disappearance of the bacterial growth seen in Petri-dish 2 is clear. The new bacteria growing in plate 1 was identified as Actinomyces, the one from which useful antibiotics can be extracted. This explains the complete inhibition of growth in plate 2

Plate 2 on the right is the one from water merely touched by a fly. There is no explanation for how the plate was produced, or how the bacteria were identified; the strange brown sludge suggests poor technique, though, and I've cultured E. coli myself — and that hideous thick fecal-colored glop looks nothing like E. coli.

Plate 1 on the left, made from water in which the fly was fully immersed, looks nasty too. It's a poor photograph, but that looks like a thick lawn of colonies everywhere. How do they know it's Actinomyces? I have no idea, they don't say. It's also a mistake to simply declare it beneficial — Actinomyces are opportunistic pathogens.

Experiment #2 was a different fly, two flasks of water, same result.

Experiment #3 was a third fly, two flasks of water, same result.

Having done the experiment to death, our brave students retired at the third repetition, wrote it up with no methods, no discussion, no literature cited (except for their holy book, of course), and no reliable, believable data. They also didn't do the other obvious experiment, of snipping off the wings and examining the bacterial flora living on the left vs. right, but then, maybe they're leaving that for the advanced students.

Any 10 year olds looking for a quick and easy science fair project, there it is. I'm sure you can replicate this experiment trivially -- but please, talk to a real microbiologist first and learn how to streak a plate. You might also learn something about a control plate, which our U of Qassim students didn't bother to do.

Of course, this work wasn't carried out by 10 year olds. It was done by university students in a "Med 497" (a medical course?) in a department of medical microbiology. I strongly urge anyone visiting Saudi Arabia to avoid getting sick. They might try to treat you by swishing a fly around in your coffee.

Ritalin's Fallacy [Dean's Corner]

Posted: 29 Jan 2012 07:47 AM PST

Some drugs work well because they are designed to hit a single, well understood target. Consider penicillin.

In a simplified sense, penicillin destroys a single enzyme that bacteria need to divide and to infect you, thereby killing the harmful bacteria. But what about psychiatric drugs? Is there a comparable, single target in the brain to treat depression, anxiety, attention deficit disorder (ADD)? No.

Another Review for the BSB! [EvolutionBlog]

Posted: 28 Jan 2012 03:38 PM PST

The Big Sudoku Book has received another review, and in an unexpected venue: The Wall Street Journal! The review is by Keith Devlin, a mathematician at Stanford University and the author of a small library of books of his own. Devlin writes:

The authors show vividly that mathematics is really about the power of abstraction, the push to explain as much as possible in the most compact form possible. Numbers and arithmetic are a part of that enterprise, but there is a lot more besides. “Taking Sudoku Seriously” is an excellent vehicle whereby devotees of the puzzle can come to understand the nature of mathematics.

Score!

Weekend Diversion: The Best (and Easiest) Charity Ever! [Starts With A Bang]

Posted: 28 Jan 2012 05:55 PM PST

"You cannot hope to build a better world without improving individuals. We all must work for our own improvement, and at the same time share a general responsibility for all humanity." -Marie Curie

Most of us remember the importance of being charitable on a few rare occasions throughout the year, most commonly around the year's end. But what about the rest of the year? Obviously, we don't have an unlimited amount of resources, so for most of us, it's not a viable option to do as Magnolia Electric Company suggests, and

Give Something Else Away Every Day.

But what if I told you there was a way to donate to charity, help advance science, and give yourself a chance to win a nice sum of money, at really no cost to you?

May I present to you The Charity Engine, the best supercomputing project I've ever heard of. You might have heard of individual projects like Einstein@Home, which has found 16 pulsars since its inception, or SETI@Home, which sifted through telescope data for signals of extraterrestrial intelligence. Both of these relied on sending unprocessed data to individual computers all across the internet, having users donate their spare processor time to doing these computations, and sending the finished work back to the server. This basic idea -- borne from the Berkeley Open Infrastructure for Network Computing -- is the core of the Charity Engine.

But the Charity Engine goes far beyond any of these projects. Let's say you've got an enormous computing job and not enough computing power to do it. I don't care whether you're a scientist, a University, or an independent company, where do you go? Enter the Charity Engine!

Charity Engine takes enormous, expensive computing jobs and chops them into 1000s of small pieces, each simple enough for a home PC to work on as a background task. Once each PC has finished its part of the puzzle, it sends back the correct answer and earns some money for charity - and for the prize fund. (It also earns more chances to win.)

Where does the money come from? Science and industry. The grid is rented like a giant supercomputer, then all the profits shared 50-50 between the charities and the lucky prize winners.

Charity Engine typically adds less than 10 cents per day to a PC's energy costs and can generate $10-$20 for charity - and the prize draws - for each $1 of electricity consumed.

It is the most efficient way to donate to charity ever invented.

As you can see, above and below, they've got an impressive array of charity partners, and a strict commitment to only rent the grid to ethical users, and to treat you, the donor, ethically, too.

You can follow them on facebook and twitter, and by joining, you can become part of what they're hoping will become the world's fastest supercomputer within a single year! For each additional dollar (or pound, or euro) you spend on electricity on this application, you generate about twenty times as much for the Charity Engine, which gets split, 50/50, between their charities and their users. (That's you!) And you never have to think about it; it only uses your CPU's idle time, and turns itself back off as soon as you try to use your machine again! (The worst thing it does is make itself your screensaver and require a restart after installation.)

Best of all, you've got a great reason to support them: they come certified by Starts With A Bang! Let's say you want to, I don't know, simulate the formation of a galaxy -- from scratch -- in the Universe?

(Video credit: Fabio Governato et al./U. of Washington/NASA Advanced Supercomputing.)

You and hundreds of other people, right? Who decides whose project is worthy of the Charity Engine's power? They'd need some kind of expert to help them decide, right?

There's an entire science panel, and yours truly sits on it, to help decide which projects get the 5-10% of the grid permanently reserved for pure science! So you're not just supporting charity, you're supporting legitimate science, hand-picked by me and the rest of the science panel! (Plus, their CEO is a huge fan of this blog, so you know there's good taste involved here!)

Read more about them at crunchbase, Fast Company, and one of Charity Engine's charity partners, OxFam. This is a great opportunity for everyone to support science, help charity, and -- for those of you who feel lucky -- maybe win a small fortune while you're at it. How can you not feel good about this; get started and help make something wonderful happen today! Read the comments on this post...

Kicking sand to catch fish [Life Lines]

Posted: 27 Jan 2012 03:06 PM PST

I really love fishing! I can't think of a more relaxing time than sitting by the lake, or a more exciting time than going deep sea fishing. Therefore, I find animals that have come up with unique ways of catching fish pretty interesting. Take for example the humpback whales that we talked about in a previous blog. These animals actually create bubble-barriers around schools of fish to keep their meal in one spot.

It turns out that bottlenose dolphins also have a unique strategy. They use sand. By hitting the ocean floor with their tails, they create clouds of sand that act as barriers around schools of fish. Brilliant.

The comparison to jabberwocky is inevitable [Pharyngula]

Posted: 27 Jan 2012 09:35 AM PST

Lots of people have been sending me this paper by Erik Andrulis, and most of you have done so with eyebrows raised, pointing out that it's bizarre and unbelievable; some of you wrote asking whether it was believable, at which point my eyebrows went up. Come on people: when you see one grand cosmic explanation that is summarized with cartoons, which the author claims explains everything from the behavior of subatomic particles to the formation of the moon, shouldn't you immediately sense crankery?

It's also getting cited all over the place, from World of Warcraft fan sites to the Discovery Institute (those two have roughly equal credibility in matters of science), so I had to skim through it. I read it with rising concern: Erik Andrulis is a young assistant professor at Case Western Reserve University, and he's published entirely sensible papers on RNA processing. This paper is so weird and out there that it is either an attempt to Sokal the field of origins of life research, or the man is seriously mentally ill. Either way, this is not going to help his career in the slightest.

The paper is titled Theory of the Origin, Evolution, and Nature of Life, and just the sweeping grandiosity of that title should set off alarm bells. Here is the abstract:

Life is an inordinately complex unsolved puzzle. Despite significant theoretical progress, experimental anomalies, paradoxes, and enigmas have revealed paradigmatic limitations. Thus, the advancement of scientific understanding requires new models that resolve fundamental problems. Here, I present a theoretical framework that economically fits evidence accumulated from examinations of life. This theory is based upon a straightforward and non-mathematical core model and proposes unique yet empirically consistent explanations for major phenomena including, but not limited to, quantum gravity, phase transitions of water, why living systems are predominantly CHNOPS (carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur), homochirality of sugars and amino acids, homeoviscous adaptation, triplet code, and DNA mutations. The theoretical framework unifies the macrocosmic and microcosmic realms, validates predicted laws of nature, and solves the puzzle of the origin and evolution of cellular life in the universe.

Having skimmed through all 105 pages of this thing, I can tell you with confidence that it answers none of those questions. Just the fact that it is entirely non-mathematical and non-empirical (there aren't any observations or experiments described at all), and that the entirety of the theory is built around diagrams sketched out by the author, should also tell you that this is not a useful or predictive theory.

It does not have an auspicious beginning. In addition to being constructed around cartoons and being a non-mathematical Theory of Everything, it has to introduce an elaborate collection of neologisms that make the whole paper painful to read.

In the theory proposed herein, I use the heterodox yet simple gyre--a spiral, vortex, whorl, or similar circular pattern--as a core model for understanding life. Because many elements of the gyre model (gyromodel) are alien, I introduce neologisms and important terms in bold italics to identify them; a theoretical lexicon is presented in Table 1. The central idea of this theory is that all physical reality, stretching from the so-called inanimate into the animate realm and from micro- to meso- to macrocosmic scales, can be interpreted and modeled as manifestations of a single geometric entity, the gyre. This entity is attractive because it has life-like characteristics, undergoes morphogenesis, and is responsive to environmental conditions. The gyromodel depicts the spatiotemporal behavior and properties of elementary particles, celestial bodies, atoms, chemicals, molecules, and systems as quantized packets of information, energy, and/or matter that oscillate between excited and ground states around a singularity. The singularity, in turn, modulates these states by alternating attractive and repulsive forces. The singularity itself is modeled as a gyre, thus evincing a thermodynamic, fractal, and nested organization of the gyromodel. In fitting the scientific evidence from quantum gravity to cell division, this theory arrives at an understanding of life that questions traditional beliefs and definitions.

Here's a partial copy of his lexicon. It goes on quite a bit longer than what I've copied here.

Table 1. Gyromodel Lexicon

Alternagyre A gyrosystem whose gyrapex is not triquantal

Dextragyre A right-handed gyre or gyromodel

Focagyre A gyre that is the focal point of analysis or discussion

Gyradaptor The gyre singularity--a quantum--that exerts all forces on the gyrosystem

Gyrapex The relativistically high potential, excited, unstable, learning state of a particle

Gyraxiom A fact, condition, principle, or rule that constrains and defines the theoretical framework
Gyre The spacetime shape or path of a particle or group of particles; a quantum

Gyrequation Shorthand notation for analysis, discussion, and understanding gyromodels

Gyrobase The relativistically low potential, ground, stable, memory state of a particle

Gyrognosis The thermodynamically demanding process of learning and integrating IEM

Gyrolink The mIEM particle that links two gyromodules in a gyronexus

Gyromnemesis The thermodynamically conserving process of remembering and recovering IEM

Gyromodel The core model undergirding the theoretical framework

Gyromodule A dIEM particle in a gyronexus

Gyronexus A polymer of dIEM particles linked by mIEM particles

Gyrostate The potential and/or kinetic state that a particle occupies in its gyratory path

Gyrosystem A gyromodel with specific IEM composition, organization, and purpose

IEM Information, energy, and/or matter

I can't help myself. You knew this was coming.

Twas brillig, and the slithy toves
Did gyre and gimble in the wabe:
All mimsy were the borogoves,
And the mome raths outgrabe.

Now I know that you are in lexical shock right now, but I'm about to make it worse. Witness the use of these terms in figure 1 of the paper, which will also reveal the kinds of diagrams he's using.

"The levorafocagyre, in turn, is antichiral to the dextrasupragyre" is a nice sentence that about sums up the experience of reading this thing. Don't believe me? Here are more excerpts that illustrate the grand, cosmic, and entirely uninformative nature of gyroexplanatory gyrobabble. Andrulis purports to explain everything from learning and memory (learning and memory by gyres, not the poor people trying to understand his paper):

The ultimate state of gyromnemesis is the stably adapted particle or gyronexus in the gyrobase. A particle thus adapts through learning and memory by completing one full cycle--a revolution-- around the singularity. Taken together, gyrognosis defines IEM integration and assessment whereas gyromnemesis defines IEM storage and recovery. Finally, although a diquantal IEM (X'') undergoes gyrognosis as the gyrobase of a primary majorgyre, it undergoes gyromnemesis as the gyrapex of an alternagyre. Thus, gyre learning and memory are relative to the gyradaptive singularity.

To the formation of Earth's moon:

Lunar Formation. The favored hypothesis for the formation of Earth's Moon is from planetesimal impact on a proto-Earth proceeded by matter ejection, accretion, and gravitational capture [189,190]. However, the question of lunar origin has not been settled since there are competing, albeit antiquated hypotheses [191,192]. I also discovered the stunning admission that, "...shamefacedly, [astronomers] have little idea as to where [the Moon] came from. This is particularly embarrassing... [193]." The oxygyre models the Moon as a macroxyon that has a macroelectron within itself; this simple gyrosystem accounts for the known chemical composition of the Moon surface, oxides [194]. Regarding lunar origin, the macroxyon that is the Moon emerges from the macroelectron that is the Earth, concomitant with the emergence of Earth's macroxyon [195,196].
Several additional points can be derived from this gyrosystem. First, the oxygyre explains water on and in the Moon [197-199]. Second, the gyrating effects of the macroxygyre model the rotation of the Moon on its axis. Third, the path of a less exergic macroxyon (Moon) around more exergic one (Earth) follows an ohiogyre path, or lunar orbit. Fourth, this oxygyre provides insight into how tidal cycling is linked to lunar orbit and axial rotation [200] since the Earth's oceans (macroxymatrix) and Moon itself (a macroxyon) exert complementary attractorepulsive forces. Fifth, this theoretical union also helps clarify short-term chronobiological ([201]; see 3.8) and long-term geophysical [202] relationships. Sixth, the craters that cover planetary, lunar, and satellite surfaces [203-205]--most if not all of which are near-perfect circles--bear the signature of the macroelectron singularity and its strong thermodynamic force on the oxygyre [206].

You know what? That doesn't explain anything!

While the strange terminology and nonsensical claims could be clues that this is an elaborate Poe of some sort, the story I've heard from some other sources is that Andrulis is not getting tenure and will be leaving Case next year, and that he seems to have a history of tuning in and out — so what this most like is is a developing personal tragedy. I hope he gets the care he clearly needs; his other work suggests that this is an intelligent mind that is currently going off the rails.

Setting Andrulis aside, though, there are other problems here. How did this paper get published? It's terrible: unreadable, incoherent, bizarre, and completely lacking in evidence or mathematical support. This is from the very first issue of a new journal, Life, which also contains a perfectly reasonable general summary of origins of life research by Stuart Kauffman alongside Andrulis's ghastly dreck. There seems to be a complete lack of editorial discrimination at the journal; this is not the way to build a reputation. Or rather, it is, but not a desirable one.

And then there is Science Daily, which seems to be the source where most of my correspondents found this paper. Science Daily is an incredibly annoying source: all they do is republish, without any kind of intelligent assessment, press releases. They suck. What good is mindless regurgitation?

And finally, there's Case Western Reserve University, which must bear a share of the blame. Where did the press release come from? Why, from the Media Relations office at CWRU. Somebody wrote the press release that begins like this:

The earth is alive, asserts a revolutionary scientific theory of life emerging from Case Western Reserve University School of Medicine. The trans-disciplinary theory demonstrates that purportedly inanimate, non-living objects--for example, planets, water, proteins, and DNA--are animate, that is, alive. With its broad explanatory power, applicable to all areas of science and medicine, this novel paradigm aims to catalyze a veritable renaissance.

It's madness stamped with the Case Western Reserve University School of Medicine seal of approval. If Andrulis did Sokal the journal, he also Sokal'ed the institution that employs him. Who wrote that bullshit? Do they have anyone competent review their press releases before they mail them out to the whole wide world? Was there anyone thinking in all the steps from crank professor to PR department to journal editor to reviewers? There were so many points where this crackpottery should have been detected and rejected, and it didn't happen.

With Focus on Wowing Elementary and Middle School Students, Life Technologies Returns as Major Sponsor! [USA Science and Engineering Festival: The Blog]

Posted: 27 Jan 2012 07:00 AM PST

As many educators know, the elementary and middle school years are critical periods in which students' interest in science can "wither on the vine" if efforts are not made early to engage young learners in such subjects in exciting and creative ways.

This is why global biotech leader Life Technologies -- as it prepares to return as a major Sponsor of the USA Science & Engineering Festival next spring.-- will devote a major portion of its outreach exhibits at the finale Expo to wowing elementary and middle school students through a wide range of interactive science activities.

"We know how important it is for kids, especially young girls, to remain engaged and motivated in science at that age," says Heather Virdo, head of Community Relations for Life Technologies." And we know how powerful science outreach can be when it is combined with exciting hands-on interaction with real-life scientists and other professionals.

"That's why," she says, "Life Technologies looks forward to returning as a Sponsor of a major public event like the Science & Engineering Festival as this gathering works to help inspire young students to become leading scientists of tomorrow and to prepare them to play an important role in developing new applications and technologies that will lead our society into the future."

Life Technologies Corporation and its Foundation, with its long history of scientific excellence and community involvement, is also known for its deep commitment to supporting the next generation of scientific leaders through education and outreach in science, technology, engineering and mathematics.

At the Life Technologies exhibits during the finale Expo in April, elementary and middle school students and their teachers will get an up-close-and personal look into the
intriguing world of bioscience research, including how Life Technologies scientists are using DNA sequencing techniques to not only better diagnose, treat and investigate disease, but to also save wild cheetahs and other endangered species, in addition to improving farming and agriculture techniques for the food we eat.

And through hands-on interaction with Life Technologies scientists and research technicians, Expo goers will also participate in genetic sequencing and human identification exercises.

"The Festival also offers a great way for our non-scientist employees at Life Technologies to also become involved with outreach," says Heather. "So members of our Human Resources, Finance and other departments will also be present to talk to students about career opportunities in these fields as well at our corporation."

Known worldwide for its innovation and leadership in scientific discovery, Life Technologies is a global biotechnology tools company dedicated to improving the human condition. Its systems, consumables and services enable researchers to accelerate scientific exploration, driving to discoveries and developments that make life even better. Life Technologies was created by the combination of Invitrogen Corporation and Applied Biosystems Inc., and manufactures both in-vitro diagnostic products and research use only-labeled products.

We thank Life Technologies and our other valued Sponsors as they join us in our goal of inspiring the next generation of scientists and engineers!

Two incontrovertible things: Anthropogenic Global Warming is Real, and the Wall Street Journal is Political Rag [Greg Laden's Blog]

Posted: 27 Jan 2012 08:40 PM PST

The Wall Street Journal has published one of the most offensive, untruthful, twisted reviews of what scientists think of climate change; the WSJ Lies about the facts and twists the story to accommodate the needs of head-in-the-sand industrialists and 1%ers; The most compelling part of their argument, according to them, is that the editorial has been signed by 16 scientists.

The scientists who signed to WSJ editorial are:

Claude Allegre, former director of the Institute for the Study of the Earth, University of Paris; J. Scott Armstrong, cofounder of the Journal of Forecasting and the International Journal of Forecasting; Jan Breslow, head of the Laboratory of Biochemical Genetics and Metabolism, Rockefeller University; Roger Cohen, fellow, American Physical Society; Edward David, member, National Academy of Engineering and National Academy of Sciences; William Happer, professor of physics, Princeton; Michael Kelly, professor of technology, University of Cambridge, U.K.; William Kininmonth, former head of climate research at the Australian Bureau of Meteorology; Richard Lindzen, professor of atmospheric sciences, MIT; James McGrath, professor of chemistry, Virginia Technical University; Rodney Nichols, former president and CEO of the New York Academy of Sciences; Burt Rutan, aerospace engineer, designer of Voyager and SpaceShipOne; Harrison H. Schmitt, Apollo 17 astronaut and former U.S. senator; Nir Shaviv, professor of astrophysics, Hebrew University, Jerusalem; Henk Tennekes, former director, Royal Dutch Meteorological Service; Antonio Zichichi, president of the World Federation of Scientists, Geneva.

It's a Real Book! [Uncertain Principles]

Posted: 27 Jan 2012 08:54 AM PST

I was going to write something about the politics of scientific publishing, but instead, I want to focus on what's really important in modern publishing:

That's right, I got a couple of early copies of How to Teach Relativity to Your Dog in the mail this morning. It's a real book, with pages and everything... You can see it above, next to How to Teach Physics to Your Dog, and various clutter on my desk, for scale.

There's not much else to say, other than "Woo-hoo!" They're printing lots more, of course, and it will be available wherever books are sold starting Feb. 28th.

Recent Archaeomags [Aardvarchaeology]

Posted: 28 Jan 2012 01:52 AM PST

British Archaeology #122 (Jan/Feb) has a good feature on the origins of Roman London, presenting and collating evidence from excavations in the 90s and 00s for a military camp immediately post-dating the AD 43 invasion of Britain. The editors have slapped a silly headline on the thing though, playing up a short passage about human heads deposited in the Walbrook stream as if this were the main issue dealt with in the piece.

The unsigned last page discusses the important work of Raimund Karl (in The Historic Environment: Policy & Practice Oct 2011; read it on-line), who has compared the results of the English/Welsh and the Austrian legal attitude to metal detecting and other situations where members of the public make archaeological finds. In the former case, the Portable Antiquities Scheme encourages the public to report their finds voluntarily. It was instituted in 1997, and reporting immediately exploded in volume. Year after year the PAS is seeing an exponential increase in the number of reported finds, and it's not just metalwork either: fieldwalking flint enthusiasts are also participating very actively. Meanwhile, Austria has put a tight lid on things: if you find anything you're legally obliged to report it within two days, only archaeology graduates can dig, and only archaeology graduates with a licence can metal-detect. The result? Reporting of the finds that are always made went down and stayed down.

"The conclusion must be that when it comes to the practice of public archaeology, openness, co-operation and education trump suppression. The law-breaking, abusive minority of English and Welsh detectorists, however should be exposed and stopped. They poison the atmosphere for everyone."

I'd like to add that law-abiding amateur archaeologists (with or without metal detectors) are not a problem that the discipline (grudgingly) must deal with. They represent an enormous resource in free labour, political clout and local knowledge that should be celebrated and made good use of. Archaeology and heritage management has incomparably better chances of reaching their goals with the public as participants than as spectators.

Archaeology Magazine #65:1 (Jan/Feb) has a great piece on underwater archaeology at the site of the naval Battle of the Egadi Islands off western Sicily in 241 BC. The Roman's beat the Carthaginians here, but there are no shipwrecks to be seen on the sea floor: shipworm has eaten the wood and recent trawling has bulldozed what was left. Still, there is one find category that survives: large cast bronze objects, such as ship rams and helmets. And Florida-based non-profit RPM Nautical Foundation is locating and lifting these things with the aid of remotely operated subs. They have six of the huge rams now! And every one of them pinpoints a spot where either a ship went down or a ram was dropped after a collision. Few naval battles of the 2nd millennium AD are mapped to such precision.

On thing that takes me aback however is the ads. Advertisers are usually pretty savvy about who the target audience of a given media outlet is. You won't see ads for home mortgages or cars on the Disney Channel. And the ads in Archaeology Magazine show clearly who reads the mag: people who might want to buy collectible coins, cruises in the Mediterranean, "The world's simplest computer ... designed for seniors", running shoes that "defy aging", simple-to-use stripped down cell phones, hearing aids, cultured pearl necklaces and staircase lifts. I wonder if the publishers expect the next generation of senior citizens to start subscribing when they retire, or if the mag will fold when the current readership kicks the bucket. It reminds me of when Skeptical Inquirer used to run an ad in every issue inviting readers to provide for CSICOP in their wills (are they still doing that?). Doesn't give a very forward-looking impression.

In issue #263 (Feb) of Current Archaeology, one of my favourite pop-arch mags, is a piece on a great new find from the famous Flag Fen in Cambridgeshire: a silted-up river channel with six well-preserved Bronze Age canoes, a fish-weir and some sacrificed weaponry. The canoes were left in that river from about 1300 to 700 BC, which opens for several possibilities: it's continuity either of everyday boat management, or of boat sacrifice, or (less likely) of where the natural waterflow liked to deposit stuff that floated downstream.

Likewise fascinating is a feature on Irish souterrains, secret underground stone-walled passages dug as refuges at ordinary farmsteads in the Viking Period. An early type allowed people to escape into the open air, but later they decided that it was better to simply crawl into the passage with your kids and a spear and stay there until the Vikings left, as if the passage was just a corridor-shaped cellar. The passages zig-zag and so it was impossible for people on the surface to find the end chambers where people were hiding at short notice. Similar passages occur in Pre-Roman Denmark a thousand years previously.

Fuel from Seaweed [We Beasties]

Posted: 26 Jan 2012 10:00 AM PST

I grew up on the coast of California, and I loved to surf. At my favorite break, Pleasure Point, the best waves were often at low tide, but low tide also meant seaweed. Lots of seaweed.

[Source]

The giant kelp of Monteray Bay is an astonishing organism. It's not actually a plant, it's a brown algae, and it can grow 12 inches per day. This rapid growth makes it an ideal resource, and a bane of surfers that get their fins caught in thick mats.

You can't tell, but it was definitely kelp that made me fall, not the fact that I was too far forward and unable to turn. No, really...

Brown algae like kelp can be harvested as a source of algin, and other types of seaweed are also used as sources for products like agar that we use in labs to make bacterial culture plates.

But there's also been a lot of interest in using different sorts of algae as feedstocks for the production of biofuels. Their rapid growth makes them eminently renewable, they require almost no effort to cultivate, no fertilizer, no fresh water, they would not use up arable land that can be used for food crops. The main draw back is that one of the most abundant sugars present in algae, called alginate, is not digestible by the microorganims currently used for biofuel production at an industrial scale. Until now.

Petrels, Albatrosses, and Storm-Petrels of North America [Greg Laden's Blog]

Posted: 26 Jan 2012 08:00 AM PST

Did you know that there is an entire group of birds called "Tube Noses" because they have tubes on their noses? Well, to be more exact, the term is "tubenoses" and the noses are beaks. The tubes are tubular nostril-like thingies that most (all?) birds have which are extra tube-like in the tubenoses. Thus the name.

Albatrosses, petrels, and storm-petrels, which includes shearwaters, make up the tubenoses, and the newly produced book Petrels, Albatrosses, and Storm-Petrels of North America: A Photographic Guide is about the North American species of this order, scientifically known as the Procellariiformes.

I love this book and I now want to become a tubenose watcher. This will be difficult from Minnesota. What makes it difficult is that Procellariiformes are ocean birds, and are truly pelagic, returning to land only to breed, and generally then only to remote islands. But there are exceptions. Some nest in the interior in the Arctic region, and they are occasionally seen on the Salton Sea and in the Sonoran desert (a 1997 report lists 27 records of this, ever).

There are four Families divided among 23 Genera made up of 140+ Species of tubenoses. (Wikipedia says there are only 108 species ... can somebody fix that please?) There are about 70 species in North America at present, or recently known. There are probably more endangered tubenoses than any other Order of bird, or if not, nearly so. They spend a lot of time in the air, a lot of time at sea, and spend so little time on land that many species can't really walk. One group, the fulmar-petrels, converges on skunks: Some of them can project a noxious liquid several feet from their mouths to discourage predators.

Vaccines are "transhumanism"? [Respectful Insolence]

Posted: 27 Jan 2012 03:00 AM PST

In the more than a decade since I first discovered, to my shock, that there are actual people out there who not only don't believe that vaccines are safe despite overwhelming evidence that they are but in fact believe that they don't work and are dangerous, I thought I had seen every antivaccine argument out there. After all, I just wrote about the tactics and the tropes of the antivaccine movement in which I reviewed, well, the tactics and tropes of the antivaccine movement. One of the favorite (and therefore most commonly used) tropes of the anti-vaccine movement is that vaccines are somehow "unnatural." There are many variants of this particular trope, for example the claim that "natural" infection is better than vaccination. This delusion sometimes reaches the point where some antivaccine parents will do something as stupid as to try to send lollipops licked by their children with chickenpox through the mail to other parents, the aim being to allow those parents to expose their children the chickenpox in order to give their children the "benefit" of "natural immunity."

Yes, I thought I had seen every variation of the "unnatural" trope so beloved by antivaccinationists that, I must admit, the following took me rather by surprise. It's on a website whose name GreenMedInfo.com tells you just about all you need to know about it. My brief perusal of the site reveals that it's chock full of "natural" medicine quackery. Consistent with this, it appears to be rabidly antivaccine, as evidenced by a little dittie by someone named Sayer, who appears to be the person responsible for this website, entitled The Vaccination Agenda: An Implicit Transhumanism/Dehumanism. it's a crank trifecta, combining antivaccine tropes, conspiracy mongering, and the natural fallacy in heaping helpings, all topped off with fear mongering implying that vaccines are somehow responsible for making us less "human." At this late date, having been in the trenches for a while, even I don't recall having seen a screed so full of crazy. It's perfect for a Friday, when, even though I rarely do "Your Friday Dose of Woo" anymore, this might have been a good candidate for it. You'll see what I mean right away:

New Planetary Systems Discovered [Greg Laden's Blog]

Posted: 26 Jan 2012 06:16 PM PST

Kepler has discovered 11 new "solar systems" with 26 confirmed planets among them. They:

Range from 1.5 Earths in radius to bigger than Jupiter
15 are between Earth and Neptune in size
They have years ranging from 6 to 143 days.

Their rockiness or gaseousness remains unassessed to date.

This artist's concept shows an overhead view of the orbital position of the planets in systems with multiple transiting planets discovered by NASA's Kepler mission. All the colored planets have been verified. More vivid colors indicate planets that have been confirmed by their gravitational interactions with each other or the star. Several of these systems contain additional planet candidates (shown in grey) that have not yet been verified. Image credit: NASA Ames/UC Santa Cruz

Also of interest is the number of transiting planets. Transiting planets are often how they find these systems to begin with; When a planet passes in front of its star (from our persepctive) we can detect it. There are a number of things that can be measured for these planets which eventually lead to a better understanding of what they are.

Our Galaxy's Next Supernova [Starts With A Bang]

Posted: 26 Jan 2012 05:29 PM PST

"The diversity of the phenomena of nature is so great, and the treasures hidden in the heavens so rich, precisely in order that the human mind shall never be lacking in fresh nourishment." -Johannes Kepler

So said the man who, in 1604, discovered the supernova that was the last to be seen, visually, within our own galaxy. Although it's likely that two others occurred subsequently, they were not visible to human eyes, and only with powerful telescopes were their remnants discovered.

But earlier this week, the first supernova of the year was discovered, in a galaxy 25 million light years away, NGC 3239. The supernova, indicated below, is now known as SN 2012a.

(Image credit: Adam Block/Mount Lemmon SkyCenter/University of Arizona.)

With a typical rate of about one supernova per galaxy per century, one can't help but wonder, as one of our perennial commenters did, what we'd see -- and how quickly we'd manage to see it -- if a supernova went off in our own galaxy.

Remember, now, there are two ways we can have a supernova, but both ways involve a runaway nuclear fusion reaction, giving off a tremendous amount of light and energy. But most of the energy, perhaps surprisingly, isn't in the form of light! Let's take you inside a star that goes supernova during those critical few seconds.

(Image credit: TeraScale Supernova Initiative.)

Although there are shocks and heat that are produced, you'll see that the interior reactions produce neutrinos, nearly all of which do not interact with the outer layers of the star! A few of them do, as do all of the protons, neutrons and electrons produced, and the overall production isn't instantaneous. But while it takes some time -- a couple of hours -- for the shock to reach the outer surface of the dying star, the neutrinos make it out almost immediately!

What this means is that when we have a star go supernova, neutrinos get emitted from it before the light does! We actually discovered this, firsthand, back in 1987.

(Image credit: NASA, ESA, R. Kirshner and P. Challis.)

When supernova 1987a went off just 168,000 light years away, it was close enough -- and we had enough neutrino detectors operating -- that we detected 23 (anti)neutrinos over a timespan of about 13 seconds. The largest detector, Kamiokande-II, contained 3,000 tons of water and detected 11 antineutrinos.

Today, the detector that sits in the same spot, Super Kamiokande-III, contains 50,000 tons of water and contains over 11,000 photomultiplier tubes. (There are many other excellent neutrino detectors around the world, but I'm focusing on this one in particular as an example.)

(Image credit: Kamioka Observatory, ICRR, The University of Tokyo.)

This setup is so amazing because it can not only detect neutrinos, but it can reconstruct the direction, energy, and point-of-interaction of even a single neutrino fortunate enough to interact with any one particle in those 50,000 tons of water!

(Image credit: Kamioka Observatory, ICRR, The University of Tokyo.)

Depending on where a potential supernova goes off in our galaxy, we would expect Super Kamiokande-III to see anywhere from a few thousand antineutrinos (for something on the other side of the galaxy) to over ten million of them, all in the timespan of just 10-15 seconds!

Neutrino detectors from all over the world would see a flood of detections like this, all at the same time, all coming from the same direction. At that point, we'd have something on the order of two-to-three hours to identify the direction of origin of those neutrinos, and point our telescopes towards that direction to try and obtain an optical view of the supernova -- for the very first time -- from its very beginning!

The closest supernova since 1987 was this one from last year, which we managed to catch just half a day after ignition, which is remarkable.

We've gotten very close -- mostly by good fortune -- with a very intense hypernova back in 2002.

(Image credit: P. Ferrero et al., Astronomy & Astrophysics, 457, 857-864 (2006).)

Even so, we didn't get to first observe this one, SN 2002ap, until 3-4 hours after first ignition. If the supernova that eventually comes is a type Ia supernova -- which originates from a white dwarf -- we have no way of predicting where in the galaxy that will occur. White dwarfs are simply too abundant, and the locations of almost all of them are simply unknown, and thought to be distributed all over the galaxy.

But if this originates from a very massive star whose core collapses under its own gravity (i.e., a type II supernova), we have a number of really good candidates, and some outstanding places to look.

(Image credit: Hubble, Chandra, and Spitzer composite image.)

Most obvious is the galactic center, the location of the Milky Way's last known supernova, and also the location of the most massive stars ever discovered within our galaxy. We're certainly going to have many type II supernovae originating here over the next 100,000 years, but we have no way of knowing when we'll see the next one. As you look at the above picture, take a moment to appreciate that it's very likely already happened, and we're just waiting for the neutrinos (and then the light) to get here!

But there are closer candidates than the galactic center.

(Image credit: T. A. Rector & B. A. Wolpa, NOAO, AURA, retrieved here.)

Look inside one of the great, star forming nebulae in our galaxy, and you're going to find some of the hottest, youngest stars you're going to find anywhere in the Universe. This is where the ultra-massive stars live, and in particular, the Eagle Nebula, above, may be home to an extremely recent supernova. The Eagle Nebula, the Orion Nebula, and many other regions filled with new stars are all great places to anticipate the next supernova.

But what about known, individual stars? While there are many good candidates, we have two in particualr that we can't help but talk about.

(Image credit: Nathan Smith (University of California, Berkeley), and NASA.)

Eta Carinae, in the very last stages of its life, could literally go supernova at any second. But it may also live hundreds, thousands, or even tens of thousands more years before it does so. Still, if we get a flood of antineutrinos originating from anywhere near its position in space, this will be the very first place we point our telescopes!

But unlike all of these candidates that are many thousands of light-years away, we have one good one that's much closer. In fact, it's the closest supernova candidate we have!

(Image credit: A. Dupree, NASA.)

Say hello to Betelgeuse, a red supergiant just 640 light-years distant. Betelgeuse is so gigantic that it literally is the diameter of Saturn's orbit around the Sun! If Betelgeuse went supernova, our neutrino detectors around the globe would detect -- all told -- somewhere in the vicinity of a hundred million (anti)neutrinos, which is more neutrinos of any type than have ever been detected in the history of the world, combined.

But unless it's one of these known candidates that goes supernova, how will we tell whether it's a type Ia or a type II supernova?

(Image credit: Goddard Space Flight Center / NASA / Nick Short.)

We can always wait, I suppose. Supernovae of different types have very distinct light-curves, and how the light dies off after it's reached its peak brightness will tell us what type of supernova we had.

But if something this exciting happens, I'm not going to have that kind of patience. Luckily, I won't need it, because a supernova within our galaxy would likely be the very first detectable observation for the newest type of astronomy: Gravitational-Wave Astronomy!

(Image credit: Fermilab / SLAC / LIGO collaboration.)

Undisturbed by the presence of, well, anything, gravitational waves from a supernova explosion should pass through the intervening star, any gas, dust, or matter completely undisturbed, arriving at the same time the front end of the (anti)neutrino pulse arrives! The wonderful thing is that -- according to our best simulations of general relativity -- type II (core-collapse) and type Ia (inspiraling white dwarfs) should give vast different signals for gravitational waves!

If we have a type Ia supernova, we expect to see three separate regions to our signal.

(Image credit: Marc Favata / Cornell.)

The inspiral phase should give a periodic pulse that increases in frequency and magnitude as the white dwarfs reach their final stage of their separation. As the ignition occurs, there should be a spike in the signal, followed by a "ringdown" phase as the ripples go away. Very distinctive.

But if we have a type II supernova, from a super-massive collapsing star, we're only going to see two interesting things.

(Image credit: Harald Dimmelmeier, José A. Font, Ewald Müller, and Markus Rampp.)

Just a huge spike -- where the supernova itself occurs -- just a tenth of a second after the core collapses, followed by a very rapidly dying (within 0.02 seconds) ringdown. And so if we want to know what we saw, all we need to do is extract the telltale signal from gravitational waves!

And if the galaxy's next supernova were to happen today, this is what we'd see!

IQ Varies with Context [Greg Laden's Blog]

Posted: 25 Jan 2012 11:27 AM PST

In a very interesting way.

As a regular reader of this blog, you know that IQ and similar measures are determined by a number of factors, and for most "normal" (modal?) individuals, one's heritage (genes) is rarely important. Putting it another way, variation across individuals in IQ and other measures have been shown again and again to be determined by things like home environment, diet and nutrition, and even immediate social context. Here's another finding supporting this:

Well, the BSB (that's the Big Sudoku Book) has now received its first review. It comes from Ed Pegg Jr., who runs an excellent website about mathematical games and puzzles and is very well-known among those interested in recreational mathematics. Did he like the book?

Along with Sudoku Masterpieces and Mutant Sudoku, this is one of the best Sudoku books ever written. And I do mean written/crafted -- too many Sudoku books are computer generated. This book shows a lot of careful craftsmanship.

He did! Go check out the rest of the review. Then go buy multiple copies before they are all gone and you are left feeling silly for not having bought one when you had the chance...

A Toy Model of the Arrow of Time [Uncertain Principles]

Posted: 25 Jan 2012 01:22 PM PST

The toy model of statistical entropy that I talked about the other day is the sort of thing that, were I a good computational physicist, I would've banged out very quickly. I'm not a good computational physicist, but by cargo-culting my way through some of the VPython examples, I managed to get something that mostly works:

The graph at the bottom of that window is the entropy versus "time" for a lattice of 20 sites with a 25% hopping probability (either left or right). The window with the colored balls at the upper left is a graphical representation-- red dots are "occupied" sites, white "unoccupied." The VPython code to do this is here: entropytestN2.py, from which you can see that I'm not much of a computational physicist, let alone a programmer (there are some really kludgey initialization steps that exist because it kept throwing strange errors when I did simpler things that should've worked, and I didn't have the patience to figure out the underlying problem).

It is, as I expected, kind of fun to play around with. I think there might be some bias built in that ends up pushing things to the right, but I'm not sure whether that's real or just my inability to recognize randomness. As expected, for small numbers of sites, you see frequent fluctuations down to zero, and as you increase the number of sites, significant decreases in entropy become much rarer.

I haven't attempted to do anything quantitative with this, because I don't know how to write data out from VPython into a form that any of my other analysis programs might use. If I think of a good way to do it, I might try to quantify this a little more, but for now, I'm happy just to have a working toy.

There could be H2O ice on Vesta [Greg Laden's Blog]

Posted: 25 Jan 2012 12:29 PM PST

Vesta is the second biggest asteroid in the famous asteroid belt between Mars and Jupiter. It has generally been thought that Vesta would get enough sun over its entire surface that water would not survive, but a recent survey of the surface indicates that deeply buried water has a chance of remaining on the asteroid near the poles, or possibly at the bottom of some deep craters.

Vesta Up Close (image by NASA)

This is interesting, in part, because of questions about the role of water in the early formation of the solar system. One of the main objectives of the Dawn spacecraft mission is to examine water (or the lack of water) on Vesta and Ceres (another asteroid).

Dawn is looking for water using the gamma ray and neutron detector (GRaND) spectrometer, which can identify hydrogen-rich deposits that could be associated with water ice. The spacecraft recently entered a low orbit that is well suited to collecting gamma ray and neutron data.
"Our perceptions of Vesta have been transformed in a few months as the Dawn spacecraft has entered orbit and spiraled closer to its surface," says Lucy McFadden, a planetary scientist at NASA Goddard and a Dawn mission co-investigator. "More importantly, our new views of Vesta tell us about the early processes of solar system formation. If we can detect evidence for water beneath the surface, the next question will be is it very old or very young, and that would be exciting to ponder."

The modeling done by Stubbs and Wang, for example, relies on information about Vesta's shape. Before Dawn, the best source of that information was a set of images taken by NASA's Hubble Space Telescope in 1994 and 1996. But now, Dawn and its camera are getting a much closer view of Vesta.

"The Dawn mission gives researchers a rare opportunity to observe Vesta for an extended period of time, the equivalent of about one season on Vesta," says Stubbs. "Hopefully, we'll know in the next few months whether the GRaND spectrometer sees evidence for water ice in Vesta's regolith. This is an important and exciting time in planetary exploration."

Opportunity Mars Rover Still Working After Eight Years [Aardvarchaeology]

Posted: 25 Jan 2012 05:20 AM PST

Dear Reader, remember the remote-controlled Mars rovers, Spirit and Opportunity? How long is it since the last time you thought of them? Opportunity landed on Mars eight Earth calendar years ago today, and it still works fine! It's mate Spirit was mobile on the Red Planet for over five years and then functioned as a stationary science platform for another year before getting killed off by a Martian winter it couldn't avoid. Amazing engineering that keeps working year after year without a technician so much as touching it.

Oppy is now at Endeavour crater and will spend the Martian winter in a sunny spot (good for battery charging), studying an interesting outcrop (image above) named Greeley Haven after planetary geologist Ronald Greeley (1939-2011). Check out the project's web site for news! And meanwhile, the Curiosity rover is cruising on towards Mars...

Dolphins might be able to learn new language [Life Lines]

Posted: 25 Jan 2012 07:38 PM PST

Researchers have discovered that dolphins might be able to learn a new language! Four captive bottlenose dolphins in Port-Saint-Pere, France have repeatedly heard recorded whale sounds during their various performances at the aquatic park. When researchers recorded the dolphins talking in their sleep, they found that the animals actually made whale-like noises as opposed to dolphin sounds. It was suggested that the dolphins might actually be practicing their performances during their sleep and might have the ability to learn a new language if studies can confirm that the sounds are in fact whale language.

Still more evidence that Morgellons disease is most likely delusional parasitosis, 2012 edition [Respectful Insolence]

Posted: 26 Jan 2012 12:00 AM PST

It's been nearly a year since I last discussed a most unusual malady. Part of the reason is that the opportunity to discuss it hasn't occurred recently; usually I need some spark or incident to "inspire" me to write about something, and there just hasn't been any Morgellons news that's caught my eye since 2010. However, another part of the reason, I must admit, is that writing about this particular condition almost always brings sufferers out of the woodwork, castigating me the way antivaccinationists like to castigate me for challenging the scientific basis of their preferred pseudoscience. I catch enough hostility from the antivaccine contingent. Before I'm reading to leap into a fray that's likely to bring more hostility--who knows? I might even be graced by a visit from a certain particularly loony advocate of this condition--my way from an entirely different contingent of woo-meisters. On the other hand, sometimes I need a change of pace, a new area to look at the application of science-based medicine to health and disease.

I'm referring, of course, to Morgellons disease. To recap (for those of you who are familiar with the condition) or to provide some background (for those of you who are not), people suffering (or claiming to suffer) from this condition complain of an intense itching, and the condition is characterized by a number of primary symptoms. These include:

Sponanteously Erupting Skin lesions
Sensation of crawling, biting on and under the skin
Appearance of blue, black or red fibers and granules beneath and/or extruding from the skin
Fatigue
Short-term memory loss
Attention Deficit, Bipolar or Obsessive-Compulsive disorders
Impaired thought processing (brain fog)
Depression and feelings of isolation

Perfluorinated Compounds (PFCs) in the bloodstream can interfere with vaccine response [erv]

Posted: 25 Jan 2012 09:00 AM PST

Non-stick pans, water-proof clothing, stain-proof carpet, pizza boxes, microwave popcorn bags, the air outdoors, the air indoors-- if youve ever been exposed to these things, you have been exposed to 'Perfluorinated Compounds' (PFCs).

Because the most common PFCs have a relatively long half-life (~4 years!), and because weve basically all been exposed, you can find PFCs in the blood of about 90% of us here in the US. Its ubiquitous. And, like with a lot of things, 'some' isnt that big of a deal, but 'more' can cause problems. The questions are where that 'some' to 'more' threshold is, and what kinds of problems can emerge.

A rather unexpected correlation emerged today in JAMA:

Serum Vaccine Antibody Concentrations in Children Exposed to Perfluorinated Compounds

Previous research indicated that PFCs had a negative impact on the immune systems of mice. How can we find out if they have a negative impact on humans? We cant inject humans with PFCs and cut out their spleens to study their white blood cells. But mice arent humans-- maybe what they saw was an artifact of 'mice' and PFCs have no impact on humans.

'Maybe' isnt good enough. So, this group of scientists went to a place where the folks eat a lot of fish (a common source of PFCs, so, if youve eaten fish, welcome to the 90%). Then they did two things:
1-- Looked at the immune response of kids (5 years old) to tetanus and diphtheria vaccines, and correlated it with the blood PFC concentration of their moms in pregnancy.
2-- Looked at the memory antibody response (aka how much the kids were protected from the pathogen) two years later (7 years old), and correlated it with their blood PFC concentration.

The higher the PFC concentration, the worse the kids reacted to the vaccines.

Enter media circus, stage left. And some of the circus was fuels by the lead author of this study himself, Dr. Philippe Grandjean.

"When the PFC concentration increases in the body, the immune system gets more sluggish and is less capable of maintaining a defense mechanism against microorganism"

You dont have data to support that statement in your paper. And wtf is 'immune system gets more sluggish'? That is a meaningless phrase. Talk like a grown up, people are not stupid.

Although the findings don't prove the chemicals themselves are harming the immune system, Grandjean said he thought that is "very likely" to be the case.

And Judy Mikovits thought XMRV was 'very likely' to cause CFS. We dont say things to the public without evidence to back it up, Grandjean.

"I don't feel comfortable with the compounds for myself and my family and would rather eliminate them," he told Reuters Health.

*frown*

He added that parents might want to avoid microwave popcorn, and treatment of furniture, carpets and clothing with stain repellants to reduce their family's exposure to PFCs.

*double-frown-all-the-way*

Say it with me everyone: Correlation does not equal causation.

What Grandjean has is a very interesting observation. The biochemical and physiological ins-and-outs of that observation are still unknown. He did not do studies with microorganisms-- he did studies with vaccines. Maybe there is some genetic quirk that has a negative effect on processing PFCs that also disturbs immune function. Maybe exposure to PFCs interferes with vaccine adjuvents (it seems PFCs and alum are in the same size range). Maybe there is something else about eating more fish that is negatively effecting vaccine responses (MERCURY!!!!!WARBLEGARBLE!!!), and PFCs are just a proxy measure that have no direct effect on the phenotype. An innocent correlation without causation, while the real culprit goes unrecognized.

Absolutely, if scientists can turn this observation into a causation, we would then know to keep an eye on PFC exposure and PFC waste in our environment. Of course. But screaming 'WOLF!!!!' when you find a dead goat that may or may not have died from a wolf attack helps no one, and can in fact be a snipe we waste time and money chasing if it turns out the wolf had nothing to do with it. I know youre excited, but be more careful with your statements, Grandjean.

If there's one thing about homeopaths, it's that they're indefatigable in their dedication to their unique brand of pseudoscience. They're also endlessly protean in their ability to induce their explanations for how homeopathy is supposed to "work" to evolve into endless forms not so beautiful. If it's not the claim that "like cures like" is some sort of immutable law of nature or that diluting a remedy somehow makes it stronger, it's pivoting to the claim that water has "memory." If it's not that, then homeopaths and homeopathy apologists invoke quantum entanglement that somehow works at the macro level, that "nanocrystalloids" are involved, hilariously off-base explanations of energy, or that there's somehow a quantum gyroscopic interaction between practitioner and patient. They also seem to have a hard time understanding that explaining exactly what homeopathy is, why it's pseudoscience, and why it's quackery is not a "misinformation campaign," as homeopath Dana Ullman has characterized it.

So when a reader e-mailed this little gem entitled Scientists investigate water memory, I couldn't help but take a look, particularly since there's this spiffy video to go with it:

HIV Snake Oil 'cure' leads to arrests in Uganda [erv]

Posted: 24 Jan 2012 09:00 AM PST

We in the skeptic community like to make fun of naturopaths and homeopaths and all the snake oil salesmen out there. While its a good ol laugh here in the West, if not nostalgic, the damage these charlatans can do in other parts of the world is not funny at all.

Long-time readers of SciBlogs might remember someone named Matthias Rath

In the battle of science versus woo...
The Dr. Will Sue You Now - A stolen chapter from Ben Goldacre's book Bad Science

Homeboy got rich taking advantage of desperate HIV/AIDS patients in Africa. Gave them some 'magic potion' of Vitamin C to ~~cure HIV/AIDS~~ HE TOTALLY DIDNT SAY IT WOULD CURE HIV/AIDS (except when he did). Men, women, children, he didnt care.

The Guardian described a case in which a pregnant woman newly diagnosed with HIV was visited at home by Rath Health Foundation employees and convinced to stop taking her antiretroviral medication in favor of Rath's vitamins; she died 3 months later.

Yes, Gary Null taking megadoses of his stupid supplements and getting sick is funny. A pregnant woman dying from AIDS complications because some quack told her to take (supposedly, could have been water) Vitamin C? Not funny.

The good news is, it appears as if African officials are becoming more aware of quackery and are cracking down on their local charlatans. From a few days ago:

Uganda's National Drug Authority recently arrested sales representatives of a company selling a drug that purports to cure HIV; the firm's owners are not licensed to sell medicine and are being sought by the police.

The drug, known as Virol ZAPPER, was being sold in 37-milliliter liquid doses, each costing about US$210; patients were advised to take 10 drops daily. It was being advertised on local radio and TV stations as a miracle cure for HIV.

$210. $210. I couldnt afford that. Disgusting.

What I really like about that second link though is that the author put together a 'trail of tears' quacks have created in Africa over the years (including Rath). A few examples:

Uganda - In 2006, the Ugandan government banned the use of a popular anti-AIDS herb remedy known as "Khomeini" , after tests found it provided no cure. Iranian Sheikh Allagholi Elahi claimed the drug - which contained olive oil and honey and cost $1,650 per dose - could cure HIV/AIDS and TB in three weeks.

Gambia - In 2007, President Yahya Jammeh was roundly denounced by AIDS activists when he said he had found a cure for HIV/AIDS and began treating citizens. Shortly after his announcement, Jammeh expelled the most senior UN official in the country for questioning his "cure".

Tanzania - In 2011, tens of thousands of people from all over East Africa flocked to the tiny village of Loliondo in Tanzania seeking a cure for several diseases, including diabetes, tuberculosis and HIV. Ambilikile Mwasapile, a former Lutheran pastor, was charging 500 Tanzanian shillings - about $0.33 - for a cup for his concoction.

Remember this the next time you are laughing at some rich, fundamentally healthy individual mindlessly repeating bullshit about homeopathy or herbal medicine or naturopathy or whatever. Disgusting.

Time to opt out of Google? [Greg Laden's Blog]

Posted: 24 Jan 2012 01:52 PM PST

Google will now follow you around the internet, as you use e-mail, search, YoutTube, and so on and so forth, as you use web browsers or your Android phone, and you can't opt out. This starts March 1st.

I'm not sure if this is a bad thing or not. It depends on exactly what they are doing. It will certainly make the Google experience a bit creepier: As you search for YouTube videos on some topic, Google may make suggestions based on information on your Google Calendar, or if you have a business trip to a certain city on your Calendar, Google may suggest which of your circled contacts on Google+ might like to know you'll be in town.

From the Washington Post:

Privacy advocates say Google's changes betray users who are not accustomed to having their information shared across different Web sites.
A user of Gmail, for instance, may send messages about a private meeting with a colleague and may not want the location of that meeting to be thrown into Google's massive cauldron of data or used for Google's maps application

Click through to the Washington Post piece if you want to participate in a poll regarding your reaction to this. So far 53% of respond ants plant to cancel their Google accounts because of this policy, 22% will not cancel, and 26% are not sure.

It's Coming Right For Us!!! [Starts With A Bang]

Posted: 24 Jan 2012 11:33 AM PST

"Events are the ephemera of history; they pass across its stage like fireflies, hardly glimpsed before they settle back into darkness and as often as not into oblivion. Every event, however brief, has to be sure a contribution to make, lights up some dark corner or even some wide vista of history... illumined by the intermittent flare of the event." -Fernand Braudel

The spectacular event of the day, however, isn't something that started on Earth. Rather, 93 million miles away, it was our Sun, early yesterday morning (about 38 hours ago as I write this), that had a brief... shall we say... outburst. NASA's Solar Dynamics Observatory got the best view of this event as it happened, looking in extreme ultraviolet (13.1 nanometer) light, and collapsed the one-hour flare into a meager seven seconds.

What you just witnessed was a relatively powerful Solar Flare, at class M8.7. (M is the second highest class, behind only X.) While it's nothing compared to the biggest ones we've recently seen, Solar Flares can occasionally spell trouble for us here on Earth.

(Image credit: NASA / SOHO.)

Why's that? Because Solar Flares are often accompanied by Coronal Mass Ejections (CMEs), as shown above in this 2002 SOHO image.

So what's so special about yesterday's Solar Flare?

(Image credit: NASA/SDO and the AIA consortium. Edited by J. Major, retrieved here.)

This Solar Flare produced a CME directed towards Earth, and since it's moving at around a whopping 1,000 miles per second, that means it's arriving... right around... NOW!

That's right, the largest solar storm since 2005 is going to hit Earth today/tonight, particularly right at the edge of the Northern Hemisphere! Here are a bunch of time-lapse views of the flare from the Sun from a number of different satellites, courtesy of space.com.

As you can see from the blue video (NASA's SOHO Satellite), there was a coronal mass ejection, followed by intense speckling on the satellite. (Did you notice that?) It turns out that that is the reason we really care about this!

A coronal mass ejection is when this heated plasma stream of electrons, protons, and heavy ions gets launched out of the Sun in a random direction in space. This charged radiation can totally do some damage to electronics; that's what the speckling you saw was! (There's a nice explanation and video by Phil, here.) What about you, you may ask?

You are fine. Know why? Because of this.

(Image credit: NASA/Goddard Space Flight Center, retrieved from SWRI.)

The Earth's magnetosphere protects us from this radiation! The magnetosphere bends the charged particles that would strike most regions of the Earth away from the equatorial regions, and funnels them only around the polar areas. As the particles come down towards Earth, they interact with the atmosphere, which does an excellent job of stopping them before they ever make it to the surface. In fact, this particular CME will mostly miss the Earth (remember, Earth is tiny on the scale of the Solar System), flying over the North Pole. Still, our magnetic field will bend some of these charged particles into the Earth's atmosphere! Know what that produces?

(Image credit: Bjørn Jørgensen; today's Astronomy Picture of the Day!)

The Aurora Borealis, or the Northern Lights! (If the flare had been below the South Pole, we'd have gotten the Southern Lights, or Aurora Australis, instead.) Anyone with clear skies in the Northern Hemisphere should go and look for them tonight; we don't know how far South they'll be visible, but even places that very rarely get aurorae might be in luck tonight!

You know who's going to get the best view?

(Video Credit: NASA, retrieved from YouTube user isoeph.)

Astronauts on board the International Space Station! You might be worried that the astronauts on board would not be shielded by the magnetosphere, and so would be in grave danger from a coronal mass ejection like this. After all, at 240 miles above the surface, there's no atmosphere to protect them by absorbing all the protons, ions and electrons!

So what does that mean; do the astronauts absorb this radiation directly?

(Image credit: NASA, retrieved from Paul Floyd's article.)

No, the ISS has a hull designed to shield them from this type of radiation. As this Universe Today article details, everyone and everything on board the ISS will be totally safe. In fact, any well-designed satellite will have shielding against the radiation from CMEs; the only pitfall is that most of them -- including GPS satellites -- were built cheaply, and don't have this type of shielding. That's the only type of danger from a flare / CME like this.

Yes, it's true that tremendous solar storms can be problematic, particularly for large power lines, plants, and grids, but this is not that storm. But the coming aurorae?

(Video credit: The Aurora by TSO Photography / Terje Sørgjerd.)

As Teri Hatcher would say, "they're real, and they're spectacular." Get out there tonight if you've got clear skies and have a look. Good luck!

How to implement IT role changes [Greg Laden's Blog]

Posted: 24 Jan 2012 08:21 AM PST

Free-Dos Fearless Leader and IT Manger Jim Hall has a post at Almost Diamonds that some of you will be interested in.

Some time ago, I posted an online poll to survey the relative importance of four qualities at various levels in an IT organization. With the help of other bloggers, and through retweets, we got the word out to as many IT folks as possible. We received responses from all across the globe (though most were from the U.S.) representing private industry, higher education, and government. The poll was up for about two months, but most of the responses came within the first few weeks. I'd like to share the results with you.

Simple Video Editing Software? [Uncertain Principles]

Posted: 24 Jan 2012 07:24 AM PST

So, back when How to Teach Physics to Your Dog was coming out, I did a few "dramatic readings" of bits of the book, such as this one on the Quantum Zeno Effect:

This was made with Windows Movie Maker, because it was free (came with the computer) and dead simple. However, Movie Maker on my new computers is hopelessly broken-- I've made a couple of attempts to do the same sort of thing with my laptop, but I've never managed to get more than a couple of steps in before it crashes. (To be fair, this is one of only two things that are worse under Windows 7 than Vista, and the only one that's Microsoft's fault...)

For that reason, I'm looking for an alternative: I need some non-Movie Maker software package that will let me do the same sort of thing I did in that video: record an audio track of me reading a bit of the book, and put together video to go with it out of still photos and maybe short video clips. I could, of course, simply Google this, but I value the opinions of my wise and worldly readers more than random reviewers on some other site, so if you know of a good (and preferably cheap) program that will let me do this, leave a recommendation in the comments.

Warning Will Robinson: There Is No Evidence of Life on Venus [Greg Laden's Blog]

Posted: 24 Jan 2012 07:32 AM PST

There is a story going around that there is evidence of life on Venus. The evidence would be very convincing if some descriptions of it were true: Scorpion or crab like creatures walking around on the surface sounds a lot like life to me! And, the research is published in a peer reviewed journal put out by one of the big publishing houses, and the paper is by a mainstream Russian scientist who's done a lot of work. But is seems to be very wrong.

The research is by Leonid Ksanfomaliti, and looks at photographs from the 1980s period landing probe. What looks a lot like a crab seen in two separate photographs is actually two fragments of lens caps that fell off of the probe's cameras (I assume they were supposed to do that). Other objects are also explained as artifacts or tricks of light.

This really wouldn't be interesting enough to mention here were it not for the fact that the version of the story where there really might be life on Venus is getting some traction, despite the widespread story of how there is no life on Venus.

This is from Yahoo, and This is from MSNBC.

Google to Address Ad Heavy Web Sites [Greg Laden's Blog]

Posted: 23 Jan 2012 08:03 PM PST

People look at Fox News and wonder how the heck it manages to be taken seriously. Most of what is done on that station is not news, and it isn't even commentary by any reasonable journalistic standards. Fox News is much of the time a mouthpiece for the Right Wing and the Republican Party. The rest of the timt, Fox News, astonishingly, seems to be giving the Right Wing and the Republican Party its marching orders. It seems to me that we can have news agencies that range across the liberal-conservative spectrum that also carry out their activities in a professional manner. In the old days, the FCC and various other agencies and organizations seemed to have some influence, even control, in these manners. Years ago I was the editor of a newspaper, and I remember learning that newspapers were classified into different categories based on percentage of advertising vs. content. In order to have credentials (i.e., your reporters get press passes, etc.) you had to be for real. If you were a rag with all ads, or a real estate handout or the pennysaver (or the newspaper I edited!) you were not for real, and you could not get press passes, or other things real journalistic enterprises get.

But that does not seem to be true any more. You can be Fox News and have a chair in the White House press room. This is preposterous.

Google has made an announcement that bears on this in an interesting way. According to Google's Webmaster Central Blog, web sites will not be penalized in the Google Search Algorithm if they have too many ads.

If you click on a website and the part of the website you see first either doesn't have a lot of visible content above-the-fold or dedicates a large fraction of the site's initial screen real estate to ads, that's not a very good user experience. Such sites may not rank as highly going forward.
We understand that placing ads above-the-fold is quite common for many websites; these ads often perform well and help publishers monetize online content. This algorithmic change does not affect sites who place ads above-the-fold to a normal degree, but affects sites that go much further to load the top of the page with ads to an excessive degree or that make it hard to find the actual original content on the page. This new algorithmic improvement tends to impact sites where there is only a small amount of visible content above-the-fold or relevant content is persistently pushed down by large blocks of ads.

This algorithmic change noticeably affects less than 1% of searches globally.

The entire memo to the webmasters is here.

Now, if only we could get Google to not count Fox outlets in the "News" category in searches. Perhaps they can add a new category for entities like fox. "Clown" would work.

What do you think?

Notes Toward a Toy Model of the Arrow of Time [Uncertain Principles]

Posted: 23 Jan 2012 09:25 AM PST

I'm fairly certain somebody has already done this, because it's such an obvious idea. It's a little beyond my cargo-cult VPython skills right at the moment, though (I can probably learn to do it, but not right now), and I none of the applets I Googled up seemed to be doing this, so I'm posting this sketchy description because I've spent some time thinking about it, and might as well get a blog post out of the deal.

So, as we said back in the holiday season, one of the most fundamental concepts in the modern understanding of thermodynamics and statistical physics is the notion of entropy. You can also argue that entropy is in some sense responsible for our perception of time-- that is, the reason we see time marching forward into the future, not backwards into the past is that entropy increases as we move forward, and it's the increase in entropy that determines the arrow of time.

We can define entropy using Boltzmann's formula:

which says that the entropy of a given arrangement of microscopic objects (atoms or molecules in a gas, say) is related to the number of possible ways that you can arrange those objects to produce states that are macroscopically indistinguishable. The more states that look the same on a coarse scale, the higher the entropy. This makes the arrow of time a sort of statistical property: entropy tends to increase because it's easy for a collection of stuff to randomly move toward a high-entropy state (which you can do lots of ways) but unlikely that a random motion will take you to a low-entropy state (which can only be made a few ways).

Boltzmann's idea is simple and powerful, but it can be a little hard to do anything more than qualitative hand-waving with it at the intro level. It's kind of hard to explain how you "count" microstates of things that are (classically) continuous variables, like the velocities of atoms in a gas, without getting infinite results.

So, here's my rough idea, that I might still try to code into a model for my timekeeping class this term: Rather than thinking about continuous variables, let's think about a lattice of points that may or may not contain an atom. It's easiest to picture in 1-d, where a low-entropy starting state might look something like this:

1 1 1 1 1 0 0 0 0 0

This represents all of the "atoms" being on one side of the lattice representing space.. Then you just allow each "atom" some probability of moving either left or right to an unoccupied space. So, for example, a few time steps later, the state might look like this:

Tactics and tropes of the antivaccine movement [Respectful Insolence]

Posted: 24 Jan 2012 12:00 AM PST

I've been an observer and student of the antivaccine movement for nearly a decade now, although my intensive education began almost seven years ago, in early 2005, not long after I started blogging. It was then that I first encountered several "luminaries" of the antivaccine movement, such as J.B. Handley, who is the founder of Generation Rescue and was its leader and main spokesperson; that is, until he managed to recruit spokesmodel Jenny McCarthy to be its public face, and Dr. Jay Gordon, who, although he swears to high heaven he is not antivaccine, sure could have fooled me. At the very minimum, he is a credulous apologist for the antivaccine movement. Then there were many more through the years: Barbara Loe Fisher, Sallie Bernard, various bloggers from the antivaccine crank blog Age of Autism, and even the new generation of antivaccine activists, such as Jake Crosby, who is, if anything, even more annoying than the old generation.

Why am I mentioning this? The reason is simple. Over the years, I think I've come to learn just about every antivaccine trope, canard, strategy, and argument there is. At least, I know all the major ones, many of the minor ones, and even quite a few of the obscure ones. I'm rarely surprised anymore, even when of late antivaccinationists have taken to referring to supporters of science-based medicine as "vaccine injury denialists," a term antivaccine activist Ginger Taylor notably used in "The Role of Government and Media," a chapter in the anti-vaccine book Vaccine Epidemic: How Corporate Greed, Biased Science, and Coercive Government Threaten Our Human Rights, Our Health, and Our Children, which was edited by Louise Kuo Habakus and Mary Holland, and now uses frequently on her blog. (That actually might be a topic for another post entirely.) So when I see people writing about the tropes and tactics favored by the antivaccine movement, I know I'm quite qualified to judge whether they know what they're talking about or not, as I've spent nearly a decade in the trenches on Usenet and in the blogosphere.

Anna Kata of McMaster University appears to know what she's talking about.

Kata is the author of a recent article in Vaccine entitled Anti-vaccine activists, Web 2.0, and the postmodern paradigm - An overview of tactics and tropes used online by the anti-vaccination movement. Her opening sets the stage:

Why, Charlie Brown, Why? [Pharyngula]

Posted: 23 Jan 2012 01:17 PM PST

Mondays are my long, long days — this is the day I get to spend 3 hours talking to students in small groups about cancer (they're young and invincible, so so far it hasn't been as depressing as I feared.) And they teach me stuff! Among the things I learned today is that there was a Peanuts special from the 1990s about cancer, titled "Why, Charlie Brown, Why". I was incredulous — it doesn't sound like the kind of thing I'd expect on Peanuts — but I looked it up, and there it was on YouTube. So I'll share. It's not bad.

The class is operating on a much higher level than this special — it doesn't mention oncogenes even once! — but the session today was a conversation about everyone's personal experiences with cancer, and yes, we did talk about television and movies and how they deal with the disease.

Antibodies in breast milk can interfere with vaccine response [erv]

Posted: 23 Jan 2012 09:00 AM PST

Readers of ERV know the basics of how breast feeding affects the immune system of breast-feeding babbies:

Fetuses (fetii?) and babbies are protected from pathogens, even though their own immune systems have not matured yet. How do they manage this feat? They steal antibodies from Mommy!

Remember yesterday I said the same antibody can have lots of different butt-ends? The same 'business end' that recognizes tetanus toxin or a variant of influenza, but different back-ends-- each different butt has a different skill set.

... Newborn Babbies steal Moms antibodies a different way! IgM and IgA antibodies have a superpower that lets them be secreted-- in tears, in saliva, in mucus, and in breast milk! As long as Babby is breastfeeding, it gets all of Mommys secreted antibodies! Yay!

So, if Mom has been properly vaccinated, she has antibodies to measles, mumps, chicken pox, etc etc etc, and those are transmitted to Babby and protect it, if Babby is directly exposed to a pathogen. If Mom is exposed, her antibodies probably keep the pathogen from replicating/establishing infection at all, so Fetus and Babby are safe if their contact is indirect too.

YAY!!!

Idiot, arrogant anti-vaxers, however, are not enslaved by reality, like you and I:

They came to the conclusion that breastmilk, which is packed with immune-building immunoglobulin A (IgA), lactoferrin, lysozyme, and various other important immune factors, inhibits the vaccine from working.

IgA is not 'immune building'. IgA from Mommy via breast milk to Babby is passive immunity. Its there for a while, but then it goes away.

And it actually turns out, Mommy-->Babby IgA might be the polar opposite of 'immune building': immune retarding:

Inhibitory effect of breast milk on infectivity of live oral rotavirus vaccines.

Again, readers of ERV will totally get this paper and what they were investigating.

Rotavirus infection causes severe diarrhea, thus severe dehydration in kids. In richer countries, those kids have access to hospitals and such where they get IV fluids and are (usually) fine. In lower income countries, those kids die, to a tune of over half a million a year.

The good news is we have vaccines for rotavirus infection!

The bad news is, it doesnt seem to be working as well in the lower income countries that *need* it to work the most. What the heck is going on? Why would a vaccine work almost perfectly in the US, and lose almost half its efficacy in Nicaragua? No sense.

Well, there is something else we have access to in 'rich' countries: Formula.

It seems that moms in low income countries breastfeed their babbies more and longer.

Do you see where this is going?

Babby gets the live attenuated rotavirus vaccine. Babby eats lunch from Mom. Moms anti-rotavirus IgA antibodies neutralize the rotavirus vaccine. Babby never makes its own antibodies to rotavirus, or doesnt make very good antibodies in response to the vaccine. Babby might not be protected from rotavirus when it stops breastfeeding.

The folks in this paper determined:

In conclusion, our findings indicate that the neutralizing activity of breast milk could be one of the many factors that might explain the lower observed immunogenicity and effectiveness of live oral rotavirus vaccines among children in developing countries. These data should encourage clinical trials to investigate whether delaying breast-feeding for a short period before and after giving the vaccine could reasonably improve the immune response and protective efficacy.

Its worth investigating whether giving Babby formula a little before/after the rotavirus vaccine will help protect Babby better. Maybe we can help save some more kids. YAY!

NO! NO YAY if you are an idiot antivaxer:

The paper goes on to say that, rather than remove vaccines so that breastmilk can do its job, women should instead remove the breastmilk to allow vaccines to do their job.

... Withholding breastmilk in order to accommodate the rotavirus vaccine, as the CDC researchers suggest, is an absolutely insane notion that will deprive children of vital nutrition and proper immune development.

... But it is ludicrous notions like these that are birthed from philosophies that view drugs and vaccines as being equal, or even superior, to natural food.

... This is how vaccine dogma works, though. The religion of vaccines does not have to offer any solid proof that a vaccine works, or that it is even safe. A vaccine can even cause the very thing it is touted as preventing, and vaccine apologists will say that it works and that it is necessary. And now in this case, these same psychopaths are suggesting that young babies be starved of real nutrition in order to improve the effectiveness of a vaccine.

Go ahead and enjoy that entire piece. Its almost funny its so stupid. But then you realize that what that asshole is saying can kill kids. And then you realize hes just some jackass bitching on the internet. He has no influence in Nicaragua or India. All he can do is write posts filled with indignant righteousness, hyperbolic vilification of his 'enemies', and such extreme idiocy Im assuming he wears velcro shoes, as there is no way someone who writes an article like that can handle shoelaces without harming himself and those around him. He is impotent.

In real life, there are real people doing real jobs actually working to make the world a better place.

And that pisses impotent idiots like Ethan A. Huff off, so he runs to the internet to BAAAAAAAAAAW to his equally impotent and equally idiotic comrades and they all pat themselves on the back and give each other blow-jobs because theyre all so smart and theyre the only ones who really care, you see (see comments).

Wow... If this doesn't tell you how obviously brainwashing agencies like the CDC, FDA, and pharmaceutical companies can be... I don't know what will?

Poor creatures if we parents dont stand up for our rigths and the rigths of our children no one will.

Too many people are so clueless because they've been busy watching Charlie Sheen implode or The Bachelor.

when we were kids people used to have their kids get infected quickly to gain permanent immunity as soon as possible such as measles parties. that was scientifically smart and devoid of all the scary side effects of todays ridiculous vaccines that burn out the immune systemm and overload it.

bottom line they don't give a crap about us at all, all they care about is pushing their poisons.

Refreshing to see so many people here with common sense.

Kids in India are 'poor creatures'. Nice. Jackasses.

But hey, thanks Ethan, for providing me with this teachable moment.
