Moon Maybe Not as Old as Previously Thought

New research suggests it's 100M years younger

(Newser) - No wonder the moon has such a youthful complexion (well, it vaguely resembles a teenager's spotty face)—new research suggests it isn't quite as old as previously thought. The standard theory was that the moon formed some 4.56 billion years ago, after another planet slammed into Earth....

Parasite Makes Mice Fearless of Cats

In an adaptation that probably doesn't end well for the rodents

(Newser) - Good news for cats: Mice are no longer afraid of them—at least mice that have been infected with a parasite common in mammals. Not only does Toxoplasma gondii leave mice less afraid and thus more likely to venture into striking distance, the effects last after the parasite has cleared,...

US Teens Are Actually Getting Healthier

More veggies, more exercise, less TV—but still not enough

(Newser) - American teenagers may not be the junk food-scarfing, video game-addicted balls of lard the media likes to make them out to be—or at least, they may not be anymore. A new study has found teens in 2010 were eating more vegetables, getting more exercise, drinking less soda, and watching...

Scientists Record 800-Foot Undersea Wave

Skyscraper-size waves can take an hour to break: study

(Newser) - Amazing, terrifying, or some combination of both? Scientists have recorded an 800-foot wave breaking at the bottom of the ocean for the first time, Nature World News reports. That's the size of a skyscraper, and these waves can take as long as an hour to break. University of Washington...

Your Body Makes Its Own Mosquito Repellent

Cloaking compounds found on skin could be used to combat bites, disease

(Newser) - Bad news for bug spray is good news for just about everyone else: Scientists have discovered a mosquito repellent that makes humans pretty much invisible to the pesky blood suckers—and your body makes it on its own. When used in larger quantities, some 24 "cloaking compounds" found on...

Scientists Finally Know What's In Your Pee

Some 3K compounds from 230 chemical classes

(Newser) - Ever wondered what makes up your pee? OK, well, 20 researchers at the University of Alberta did, and they've spent the last seven years developing a urinalysis or—put simply—an encyclopedia of pee. They've made an interesting discovery, too; Medical textbooks may now need to add an...

Down Syndrome 'Reversed' in Mice

Researchers were able to affect the growth of the cerebellum

(Newser) - We'll start by tempering expectations: The breakthrough you're about to read about has "no direct link" to a human treatment, reports AFP , but it's noteworthy nonetheless. Scientists say they've identified a molecule that "reverses" the effects of Down syndrome in mice. The molecule is...

Right- or Left-Brained? There's No Such Thing

Study finds we have no preference for one side over the other

(Newser) - If you've long lauded your powerful right brain for providing you with your artistic prowess, some University of Utah researchers have bad news for you: The whole right-brain/left-brain thing isn't true. The neuroscientists analyzed 1,011 brain scans to come to their conclusion about whether people are indeed...

Scientists Uncover Clue to Jet Lag

Blame a protein called SIK1

(Newser) - The next time you're battling jet lag, go ahead and curse SIK1. That's the protein that apparently prevents our body clocks from resetting, according to a new study . Researchers studied some 100 genes that start working when they're exposed to light to help recalibrate one's body...

Being Poor Lowers Your IQ

Study suggests a 13-point drop for those in poverty

(Newser) - Poverty doesn't just take a physical toll—it actually lowers a person's IQ, suggests a new study in Science . Researchers found that the IQ of those under constant financial strain dropped as much as 13 points, about the same effect as a night without sleep, reports the Washington ...

Truth About Last Ice Age Found in Antarctic Ice

Study: Turns out warming happened around the same time everywhere

(Newser) - December 2011 saw the end of a five-year effort to recover the longest ice core ever drilled by the US. About half of the more than two-mile core, taken from the West Antarctic Ice Sheet Divide, has been now been analyzed, taking scientists back through 30,000 years of annual...

Study: It's easier to read about a 30-year-old man getting beaten than a puppy

(Newser) - What's harder to watch: An adult human kicking a puppy or an adult human kicking another adult human? Science says: the puppy. A new study has found abused dogs—both puppies and grown-ups—elicit more sympathy than abused adult humans. Abused human kids, however, are equally sympathetic as abused...

Humans Became Monogamous to Stop Infanticide

Study finds the origins of monogamy are not so romantic

(Newser) - Scientists believe they may have discovered the reason most humans, at least in theory, are so wedded to the idea of monogamy, and the answer ain't "true love." As a species, we became predominantly monogamous so other humans wouldn't kill our babies, according to a new...

Plastic Surgery Won't Make You Look Much Younger

Or much more attractive, according to strangers: study

(Newser) - Think plastic surgery will make you more attractive while shaving a decade off your appearance? A new study says that's bogus. Thanks to the honesty of strangers, researchers found plastic surgery makes a person look only 3.1 years younger on average, and only very slightly better looking, NBC...

Study: Teeth Can Be Made From Urine

Chinese scientists managed to grow teeth-like structures

(Newser) - It's a scientific feat equal parts fascinating and stomach-turning: Scientists have been able to grow "rudimentary teeth" from urine, reports the BBC . Suspend your disbelief, and read on: The Chinese team's process, as outlined in Cell Regeneration Journal, had researchers harvest cells from urine and then convert...

Study: Mosquitoes May Be Making Kids Fatter

Asian tiger mosquito is keeping kids inside and inactive

(Newser) - Blame for childhood obesity on too many cheeseburgers and ... mosquitoes? So says a new study from Rutgers University, which suggests the itch-inducing pests are so bothersome they're keeping kids indoors and inactive in summer. The study isn't an iron-clad one—researchers had a relatively small pool of about...

Scientists Give Mice Fake Memories

Study could help explain our own false memories

(Newser) - Congratulations, science: You have now advanced far enough to confuse mice. A team of researchers has managed to implant a false memory in mice, in an experiment that they hope will shed light on the unreliability of human memory.
