This week on Picks, we’ve got a great selection: the science (or pseudoscience?) of sleep apps, Nobel guinea pigs, “clean eating,” dinosaurs, the computer that smells and so much more…
Sleep Cycle App: Precise, or Placebo? by Jordan Gaines Lewis
Thanks to the Internet, it’s the age of self-diagnosis. People like to learn about (and treat) themselves through technology. Especially when pretty graphs are involved. As a sleep researcher, I was interested in my friends’ use of sleep-tracking apps, and I received a pretty positive response when I prompted them for their thoughts.
Keepers of the Oil: The Science of Fried by Rachel E. Gross
Larry Fyfe will not wait in line. But for 45 years, he’s made his living off people willing to wait in his lines. Fyfe runs four concession stands at the Iowa State Fair, most of which specialize in deep-fried foods on sticks. In 1999, Fyfe introduced the hordes to fried Twinkies. This year he served up nearly 10,000 fried Oreos. “I’m glad people aren’t like me,” Fyfe says. “I won’t stand in line for anything.”
Nobel guinea pigs by Ian Le Guillou
Although nearly 85% of Nobel Prizes in Physiology or Medicine have relied upon animal research, a few laureates have used themselves as guinea pigs. Below, UAR details some of these self-experimenters, who each took a risky step for their own reasons – bravery, desperation and hope.
The other selfie: a single case study experiment on “clean eating” by Kathleen Raven
Since I began routinely reading Scientific American comments online and in the magazine’s letters to the editor, I’ve encountered a recurring theme: Readers lament that the celebrated publication isn’t as scientific as it once was in the fifties or the nineties (depending on who is writing). Complaints pile up. Teeth gnash. But no disgruntled reader, to my knowledge, has offered solutions beyond complaints. Since commenters keep their arguments shallow, I don’t give them much credence.
That’s one small step for dinosaur-kind.. by Collin VanBuren
It seems that ever since the first dinosaur was mounted in a museum, palaeontologists have been curious about dinosaur limb posture and locomotion. The posture of the back legs was determined early on as being upright (completely vertical, like that of an elephant or a lion) as opposed to sprawling (splayed out to the side, like the limbs of crocodilians and most lizards). However, the jury’s still out on forelimb posture and mobility in dinosaurs.
What Do Your Hands Say About You? by Dana Smith
When I tell people that I ‘do psychology’ I typically get one of three reactions. 1) People ask if I can read their thoughts. No, unless you’re a drunken guy in a bar, in which case, gross. 2) They begin to tell me about their current psychological troubles and parental issues, to which I listen sympathetically and then make it clear that I got into experimental psychology because I didn’t want to have to listen to people’s problems (sorry). Or 3) they ask me a very astute question about the brain that 9 times out of 10 I can’t answer. This last option is by far the most preferable and I’ve had several very interesting conversations come out of these interactions.
Predicting what your food smells like just got easier by Adam Kucharski
Familiar everyday odours such as coffee and red wine are produced by a blend of different substances. Given that we know aroma is nothing but a mix of volatile chemicals, can we understand them enough to predict the smell they will produce? Our sense of smell is driven by an “olfactory system”, but scientists have remained puzzled as to exactly how it works. Being able to crack this nose code would help reveal how the brain processes scents. It may also bring riches to companies that can exploit such a technology.
