Too Little Sleep Is Same for Brain as Too Much Booze

UCLA study zeros in on how individual cells slow down during sleep deprivation

(Newser) - When you don't get enough sleep, parts of your brain are going to take catnaps the next day, even while you're ostensibly up and awake, a new study suggests. The results can have real-world consequences, says lead researcher Itzhak Fried of UCLA, who uses the example of a...

Scientist thinks they may have been used for powerful slashing

New research in the Lancet finds patients who undergo morning heart surgery are twice as likely to suffer heart issues and other complications as patients who have surgery in the afternoon, per the BBC . It'...

One Whiff of Blood Molecule Separates Hunters, Hunted

Scent of E2D triggers widely different reactions in animals, including humans

(Newser) - Scientists have zeroed in on a molecule in blood whose very scent triggers alarm in humans but also beckons predators. In fact, one whiff of the E2D molecule causes animals of all kinds to act in "diametrically opposite" ways, suggesting that it's been around for eons and responses...

Alligator experts thought James Nifong was kidding when he asked if it was possible

(Newser) - As far as research goes, it sounds pretty intense: pumping the stomachs of 500-plus alligators—"live and alert" ones at that. It was part of James Nifong's study on whether American alligators on the Atlantic and Gulf coasts eat sharks, and the answer might surprise you: yes. The...

No Proven Benefits, Several Risks to Eating Placenta

Placenta capsules may carry bacteria, heavy metals: study

(Newser) - The trend of eating placenta after childbirth "borders on cannibalism" and is only lining providers' pockets, rather than offering any benefit to women or their newborns. That's according to researchers of a study published in the American Journal of Obstetrics & Gynecology, which finds "no known scientifically...

Yellowstone's Supervolcano Could Erupt in a 'Geologic Snap'

Eruption process could take just decades, rather than centuries

(Newser) - Should it ever erupt, a supervolcano beneath Yellowstone National Park could blanket North America in an ash cloud, wipe out communications, and alter the climate. Given that eruptions of supervolcanoes buried on our planet—and there are several—are thought to occur every 100,000 years or so, however, the...

Why Today's Teens Don't Act Their Age

'Helicopter parenting' is one factor, researchers say

(Newser) - Compared to a generation ago, today's young people are dawdling when it comes to experiencing behaviors traditionally seen as precursors to adulthood: drinking, driving, having sex, and joining the workforce. As a result, they're often called "lazy"—but that's not exactly accurate. According to researchers,...

A new study found that after a person gets a tat, nano traces of the ink containing preservatives and contaminants work their way into the...

There's Not Much Evidence That Drinking While Pregnant Is Bad

But you shouldn't do it anyway, researchers say

(Newser) - Researchers say up to 80% of pregnant women in the UK, Ireland, Australia, and New Zealand have had an alcoholic beverage during their pregnancies—some due to the fact that they didn't realize they were pregnant when they threw one back, the Guardian notes. But getting that "positive"...
