Name that UFO (Unidentified Floating Object)

In which we ask our enlightened readers to solve a household mystery. Scene: The Check-Hayden kitchen. Erika (opens the refrigerator): Hm, this apple juice has been in here for a while. I should probably just finish it off.

Valentine’s Day Tips from the Animal Kingdom

I’m not a big fan of Valentine’s day, but I love the ads. They are so utterly, transparently awful that they cross the line from crassly offensive into entertaining. Business Insider just did a brilliant roundup of the worst offenders of all time. They have a certain evolutionary-psychology simplicity to them — if you present […]

Improve Your Memory With Reverse Peristalsis

I’m not in the habit of feeling sorry for members of the British royal family. But last month, when the press reported that a pregnant Kate Middleton had been hospitalized with hyperemesis gravidarum, my stomach lurched in sympathy. Pregnancy-related hyperemesis is usually described as “severe morning sickness,” but that doesn’t capture the suffering it involves. […]

Guest Post: The Wine Grapes of Westeros

Thanks to HBO’s Game of Thrones, I’ve become engrossed by George R. R. Martin’s remarkable setting that sometimes feels more like medieval historical fiction than fantasy. It’s the first time I’ve admired a fantasy setting in years. Its gray-shaded characters and the complex society of Westeros, where most of the story takes place, brings a relatable […]

Although no single factor is responsible for the nation’s weight gain, soda seems to be at least partly to blame. A decades-long study published earlier this month found that […]

The Sweetness of Human Evolution

Quite by accident last week, I came across something, an ethnographic detail really, that captured my imagination, and that has clearly delighted and puzzled anthropologists and even contributed to a new theory of human evolution. The detail concerned the Hadza, 1000 or so modern hunter-gatherers who speak an ancient click language and who live in […]

Kitchen Catalysts

The other day I was sitting in the bathroom, lamenting the decline of my bathroom reading material. At its zenith, the back of my toilet was heavy with Nature. (I inadvertently impressed one of my grad school classmates, who didn’t know that I thought I was subscribing to a magazine with lots of photos of […]

The Baijiu Bender

During a recent reporting trip to central China, I went to a banquet honoring a group of visiting foreign scientists. I’d heard about these banquets: red tablecloths, elaborate dinnerware, a procession of courses long enough to turn eating into an athletic event. But what were these miniature wineglasses, filled so deftly with clear liquid? The […]
