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

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...

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...

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.

Study Links Women's Height to Cancer

Taller women at greater risk

(Newser) - Good news, short women: you may not be able to reach the top shelf without a chair, but you might be less likely to get cancer. A new study of nearly 145,000 post-menopausal women found a strong correlation between height and cancer risk—stronger even than the correlation for...
