The beverage industry has been pushing the idea that you need to be drinking water and sugar water all day long, but according to Oakland University exercise physiologust Tamara Hew-Butler DPM, PhD, that's not true. "Our bodies already possess an extremely sensitive measure of dehydration," she says in this entertaining mythbusting video. "It's called thirst." Read the rest
The Morbid Anatomy Museum recently acquired a 19th-century phrenological death mask. Liza Young, a museum studies student at St. John's University, tracked down its history. Read the rest

The Mutter Museum — a freaky fantastic collection of medical curiosities — is trying to restore and preserve a collection of 139 skulls that were once used to debunk the pseudoscience of phrenology. You can help by adopting a skull for $200

It's not just that bad information on the "dangers" of vaccines is working to reduce the number of children getting vaccines — a fact that affects herd immunity. Now, there's evidence that the fake scares (and efforts to debunk them) are getting in the way of scientists publishing real evidence about actual problems with certain vaccines
. These aren't the kind of broad "vaccines are poison" claims you're familiar with. Instead, we're talking about legitimate science documenting side effects that are usually very rare, but still have an impact on certain subsets of the population and need to be addressed. Read the rest
Some pseudoscience is pretty obvious. I think most of us are comfortable saying that the world will probably not end this December, in accordance with any ancient prophecy. But distinguishing fact from fiction isn't always simple. In fact, "fact from fiction" might be too simple a way to even frame the question. In reality, we're sometimes tasked with spotting misapplication of real science. Sometimes, we have to tell the difference between a complicated thing that nobody understands yet very well but which is likely to be true and a complicated thing that nobody understands yet very well but which is not likely to be true.
Basically, it's messy.
Emily Willingham at Forbes has some helpful hints for how to make these distinctions. She offers ten questions that can serve as guidelines for approaching new topics you're skeptical of — questions that, taken all together, can help you see the patterns of pseudoscience and make informed decisions for yourself and your family.

3. What kind of language does it use? Does it use emotion words or a lot of exclamation points or language that sounds highly technical (amino acids! enzymes! nucleic acids!) or jargon-y but that is really meaningless in the therapeutic or scientific sense? If you’re not sure, take a term and google it, or ask a scientist if you can find one. Sometimes, an amino acid is just an amino acid. Be on the lookout for sciencey-ness. As Albert Einstein once pointed out, if you can’t explain something simply, you don’t understand it well.
At The Guardian, blogger GrrlScientist is passing out Nobel Prizes for Quackpottery in the fields of physiology
, and chemistry. The prizes are awarded to actual Nobel Laureates who have made deep and long-lasting contributions to undermining their own credibility by latching onto hypotheses they can't back up with evidence and then continuing to promote those hypotheses despite the lack of evidence. It's a nice reminder that scientists are human, and that even very, very smart people are not always rational people. Read the rest
Alexis Madrigal on the weird tape that Olympic athletes are sticking on themselves:
It's called kinesio (or just 'k') tape. Athletes use the tape as a kind of elastic brace that they say helps relieve pain. The tape and technique were developed by Kenso Kase thirty years ago in Japan. Since then, many companies have developed similar adhesive tapes and they are in something of a marketing war. Unfortunately, the evidence that k tape does much of anything is scant.
Huh, I never would have thought that athletes, trained to succeed at all costs and given a perfunctory education, would be so easily sold on quackery and the promise of biological shortcuts.

Over at Download the Universe, Ars Technica science editor John Timmer reviews a science ebook whose science leaves something to be desired. Written by J. Marvin Herndon, a physicist, Indivisible Earth presents an alternate theory that ostensibly competes with plate tectonics. Instead of Earth having a molten core and a moveable crust, Herndon proposes that this planet began its existence as the core of a gas giant, like Jupiter or Saturn. Somehow, Earth lost its thick layer of gas and the small, dense core expanded, cracking as it grew into the continents we know today. What most people think are continental plate boundaries are, to Herndon, simply seams where bits of planet ripped apart from one another.
The problem is that Herndon doesn't offer a lot of evidence to support this idea.

Once the Earth was at the center of a gas giant, Herndon thinks the intense pressure of the massive atmosphere compressed the gas giant's rocky core so that it shrunk to the point where its surface was completely covered by what we now call continental plates. In other words, the entire surface of our present planet was once much smaller, and all land mass.
I did a back-of-the-envelope calculation of this, figuring out the radius of a sphere that would have the same surface area as our current land mass. It was only half the planet's present size. Using that radius to calculate the sphere's volume, it's possible to figure out the density (assuming a roughly current mass). That produced a figure six times higher than the Earth's current density — and about three times that of pure lead.
Seriously. If you haven't figured out by now that the world is not ending and that any Mayan predictions claiming otherwise are largely fabricated pseudoarchaeology, then I'm not sure that I can help you. One last try, though. Please read this excellent FAQ
, written by actual archaeologist (and my former professor) John Hoopes. I did an interview with Dr. Hoopes last year about the 2012 as a phenomenon
, but the new FAQ covers, in detail, why a 2012 apocalypse is bunk, and what sources you can check out to find further accurate information about the confluence of ancient Mayan mythology and modern Western mythology. And that is all I have to say about this for the rest of the year. Coming in 2013, though: Lots of stories about Mayan archaeology

Ever wonder why some anime and video game character profiles tell you about the character's blood type? Check out this fascinating post at the Providentia blog about the use of blood types as horoscopes and personality tests in Japanese culture
. The practice has origins in early-20th century racist pseudoscience, and it can still negatively affect people today. For instance, somebody with Type B blood might have a hard time finding a job. (Via Jack El-Hai) Read the rest
