Is the Five Second Rule real?


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

Two redheads can have a brunette child

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

What makes dry quicksand so deadly?

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

Tesla vs. Edison vs. The Myth of the Lone Inventor

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

Not-exactly-near-death experiences

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

Tired? You're not filled with tryptophan, but with food

Somewhere around the late 1990s, blaming tryptophan consumption for post-Thanksgiving lethargy became as much of a holiday tradition as the food itself.
