Imagine you’re in Antarctica. It’s cold. You’re cold. Your joints ache, old wounds are reopening to ooze pus, and your teeth loosen, threatening to fall out one or two at a time. What do you feel like eating? How about ”a piece of beef, odiferous cod fish and a canvas-backed duck roasted together in a pot, with blood and cod-liver oil for sauce?”
If this sounds delicious, then your stomach serves you well. That’s how famous polar explorer Frederick Cook described the taste of penguin meat, and that is how you cure yourself of scurvy in Antarctica when fresh vegetables are nowhere to be found. Fresh meat—lightly cooked or raw—contains vitamin C, whose deficiency causes scurvy and the delightful symptoms described above.
Unfortunately for turn-of-the-century Antarctic explorers, most expedition leaders were not as enlightened as Cook and many a man succumbed to scurvy. Unfortunately for Antarctica’s penguins, they were also easy prey for the men who did eat them. “Long lines of curious penguins marched across the ice and right into camp, which almost always meant death as dog food, human food, or fuel for the boiler. A stew of penguin heart and liver became a crew favorite,” describes Jason C. Anthony in a paper on Antarctic cuisine in the Heroic Age in Endeavour.
It should come as no surprise that scientists have spent many hours contemplating new tortures for the chocolate-addicted. After all, how else will science know how much, say, boredom, will affect chocolate intake? Or stress? Or watching a psychologist unwrap a chocolate bar? These are the important things, people.
The latest edition of this research addresses a question close to many a cubicle drone’s heart: will exercise reduce the amount of chocolate you eat while at work? (more…)
It’s almost Thanksgiving here the US. Before you tuck into your stuffing, pumpkin pie, and cranberry sauce, save a little room for a big helping of science. Here are a few of our favorite Thanksgiving science stories from around the Internet, detailing the research behind fattening turkeys, giving thanks, post-holiday shopping, and more: (more…)
Making a living as a writer is tough, but if you can drink your words, everything will start looking up. A maker going by the handle Morskoiboy has built a typewriter with syringes for keys that does just that: each syringe sucks up a different fluid for each letter, runs the fluid through a microfluidic-style screen to display the letter, then drains the fluid, which can be any booze or mixer you like, into a glass.
For those of us for whom multitasking is a high art, a South Korean retail experiment combining grocery shopping with commuting looks like a godsend.
In a bid to boost online sales, grocery retailer Tesco covered the walls of a Korean subway station with photos of its merchandise arranged on store shelves. Each item was endowed with a QR code, those black-and-white squares recognized by smartphones, and commuters on their way in to work could snap pictures of the codes with phones to fill a virtual shopping cart. They paid for their items via an app, and the food was delivered to their homes after they got home from work.
No after-work grocery shopping crush, no squeaky-wheeled carts, no post-apocalyptic check-out lines. Just a little less time devoted to playing Angry Birds on the platform.
Have you ever eaten a single potato chip or French fry that sent you spiraling into nearly uncontrollable gluttony? Scientists are now saying that these sober binges are actually quite similar to pot smokers’ notorious bouts of the munchies: fatty foods cause your body to release marijuana-like chemicals called endocannabinoids, and this likely compels you to continue stuffing your face.
“Advertising for monkeys” is just too good a phrase to pass up.
Even since ads created for a study investigating whether monkeys respond to billboards debuted at the Cannes Lions ad conference, the headlines have been flowing freely. We learn Yale primatologist Laurie Santos and two ad executives came up with the idea at last year’s TED, after Santos gave a talk on her experiments showing that monkeys that learn to use money are as irrational about it as we are.
Ad firm Proton has now developed two billboards to hang outside capuchin monkeys’ enclosures, and the researchers plan to see whether they will prefer one kind of food, or “brand,” over another when it is shown in close proximity to some titillating photos, including a “graphic shot” of a female monkey exposing her genitals and a shot of the troop’s alpha male with the food.
Congratulating yourself on that calorie-conscious salad might just make you feel hungrier, scientists are now finding—better to close your eyes, take a bite, and pretend you’re eating ice cream.
We’ve already heard in recent years that eating imaginary M&Ms or cheese cubes can give you some of the satiety of the real thing: In a 2010 paper, researchers found that contrary to popular belief, imagining eating such foods in vivid detail actually made subjects eat fewer M&Ms, cheese chunks, and so on. Now, scientists have found that if you believe a shake is low in calories, you’ll feel less satisfied than people who think the shake was an indulgence, even when you’re both drinking the same shake. What gives?
Human Chorionic Gonadotropin (hGC), a hormone produced during pregnancy, is isolated from the urine of pregnant women and used to treat infertility. Since the 1950s, however, it’s also been used as a weight-loss aid—and still is, even though there’s no solid evidence showing it works.
But taking hCG could be worse than just ineffective: A new study shows that doses of the hormone can transmit prions, the misfolded proteins that cause mad cow disease and its human equivalent, Creutzfeldt-Jakob disease, an invariably fatal form of dementia that riddles the brain with holes (photo).
That’s right: There’s a potential risk of contracting deadly, brain-destroying illness by injecting yourself with proteins taken from other people’s urine—and you won’t even lose weight.
Picture yourself as one of England’s majestic Bewick’s swans, about to take off on your annual long-distance flight to Arctic Russia, when out of nowhere a scientist grabs you and methodically gropes and measures your butt. It’s all for your own good: Researchers are hurriedly sizing up as many round rumps as they can lay their hands on, in a bid to understand what’s wiping out their population.
Smaller than the more common mute swans, which stay in Britain yearlong, Bewick’s swan has seen its population in Europe decline from 29,000 to 21,000 between 1995 and 2005, and researchers at UK’s Wildfowl and Wetlands Trust (WWT) in Slimbridge, Gloucestershire, are willing to fondle the birds to save them.
They’re sizing up swans to test whether changes in the their habitat are to blame for their decline: The size of swan keesters indicated whether they have enough fat to survive their over-2,000-mile journey. Basically, if the birds are plump, then that rules out the possibility that they aren’t getting enough food, and opens the playing field for other culprits, such as power line collisions, lead poisoning, and hunting.
