"Why Are We Grossed Out by Women With Armpit Hair?"

I'm not sure the answer is right, but your mileage may vary.

The answer, it seems, is embedded deep in the evolutionary nature of disgust. And in the central role sex plays in the evolutionary story.

"How Understanding Randomness Will Give You Mind-Reading Powers"

I don't know about "mind-reading," but it will make you better informed than the average person.

More recently, psychologists Amos Tversky and Daniel Kahneman proposed the so-called Law of Small Numbers, a theory that accounts for human misunderstandings of randomness. Specifically, we wrongly expect small samples to behave like very large ones. So if you toss a coin five times, you assume that you'll get some variation of a pattern that includes two or three heads and two or three tails. If your coin lands on tails five times in a row, you tend to believe that it can't be a coincidence. But in fact, the odds of five tails in a row are 1 in 32—not especially common, but not terribly rare, either. "So we have all these sort of false positives where we figure there must be something wrong with that coin, or maybe the person's got some magic hot-hand in tossing coins," Poundstone says.

"Medical research: Treat ageing"

Absolutely! Column in Nature.

By 2050, the number of people over the age of 80 will triple globally. These demographics could come at great cost to individuals and economies. Two groups describe how research in animals and humans should be refocused to find ways to delay the onset of frailty
