A large-scale, long-term double-blind study found that low testosterone levels were far, far lower than previously suspected, and showed that taking testosterone supplements didn't confer most of its reputed benefits -- no memory improvement and no physical vitality.

All lies lead to the truth. For over 20 years, Snopes.com has been the Web's primary bullshit detector and debunker, from death by Pop Rocks to political lies. We need Snopes more than ever. For a Webby Awards exclusive feature, I commissioned talented journalist Rob Walker to explore the history of Snopes and founder David Mikkelson's relentless obsession with, of all things, the truth. From the article:

In the heat of the Republican presidential primary, Jerry Falwell Jr. appeared on The Sean Hannity Show to talk about the Donald Trump he has gotten to know—a man defined by “stuff the public never hears.” So he shared an anecdote about the time the billionaire’s limousine broke down, and a random passing couple stopped to help. Later, these Good Samaritans got some surprising news: As a gesture of thanks, Trump had paid off the their home mortgage. “Pretty impressive,” Hannity declared.
But wait a second. Who exactly were these people, and why couldn’t the limo driver just call AAA? Impressive as this anecdote sounds, is it true? Well, what does Snopes say? Founded more than two decades ago, Snopes.com was originally devoted to researching all manner of just-so tales and urban folklore sourced to a friend of a friend, or to no source at all. These days, when readers “submit a rumor” they’d like confirmed or debunked, it’s likely to be a tale tied to current events. And yes, Snopes founder David Mikkelson recognized that “impressive” Trump anecdote immediately.
“That same story had been told for years,” he says.
Paul Dawson, a professor of Food Science at Clemson University, investigated the history of the "Five Second Rule" and ran experiments to see how much bacteria actually transfers from the floor onto dropped food. Read the rest

The Skinner Box, as applied to human infants, was not what you think it was. Psychologist B.F. Skinner did not raise his daughter inside a box without human contact. Nor did she later grow up to be crazy and commit suicide because of said lack of contact. In fact, just a few years ago, Deborah Skinner Buzan wrote a column for The Guardian debunking those powerful urban legends herself.
Instead, what Skinner did was build his daughter the sort of crib that you might expect a scientist raised in the era of mid-20th-century Popular Science-style scientific futurism and convenience to build. He called it the "Air-Crib" and it was designed to maintain a perfectly comfortable temperature, provide baby Deborah with built-in toys to keep her entertained, be simple to clean, and make it easier to stick to the "cry it out" and heavily regimented feeding/sleeping schedules that were, at the time, standard parenting advice.

Turns out, whether or not you are a ginger is not determined by the simple genetics of a single gene. In fact, the pigment that causes red hair is likely present in many brunettes. What matters more seems to be how much of the ginger-hiding brunette pigment you have — and the genetics that determine that are a lot more complicated. Which, frankly, makes the brunette-guy-with-red-beard phenomenon make a whole lot more sense. Read the rest
Dry quicksand was a mythical substance — normal-looking sand that could swallow you in a flash. That is, until 2004, when scientists made the stuff in a lab. (Mark told you about that development.)
In this video, geologist Matt Kuchta explains how dry quicksand is different from both wet quicksand and stable sand. Hint: Think "Jenga". Read the rest
We're going about this feud all wrong says Matt Novak, who blogs about techno-history at Paleofuture. "The question is not: Who was a better inventor, Edison or Tesla? The question is: Why do we still frame the debate in this way?" Novak asked in a talk yesterday at SXSW. He's got a damn fine point. The myth of one guy who has one great idea and changes the world drastically distorts the process of innovation. Neither Tesla nor Edison invented the light bulb. Instead, the light bulb was the result of 80 years of tinkering and failure by many different people. Novak's point (and one I tend to agree with): When we buy into the myth, it gets in the way of innovation today. I've only been able to find a couple of small bits from this talk — a write-up by Matthew Van Dusen at Txchnologist and a short video from the Q&A portion where Novak talks about Tesla, Edison, and the Great Man Myth with The Oatmeal's Matthew Inman. But, rest assured, this is something you'll see more of at BoingBoing soon. Read the rest
In 1990, researchers investigated the stories of 58 people who had had a near-death experience during surgery. Turns out, 30 of those people were never actually near-death, at all. They just thought they were. Read the rest
Somewhere around the late 1990s, blaming tryptophan consumption for post-Thanksgiving lethargy became as much of a holiday tradition as the food itself.
