Neanderthals 'Not Fully Extinct'

Most of us have a speck of caveman, studies show

(Newser) - The latest big finding on Neanderthals : Some 20% of caveman DNA made its way into the human genome thanks to mating between humans and Neanderthals, though people today typically have only 1% or 2% of the stuff. (People have different parts of the DNA, which collectively represent what's left...

Study: It's Not McDonald's Fault Our Kids Are Fat

It's the fatty, sugary foods they're eating the rest of the time that's to blame: study

(Newser) - Fast food isn't making your kids fat—not really. What's truly behind the trend of childhood obesity are the sodas, frozen pizzas, and cookies consumed at home, school, and whenever kids aren't in a McDonald's or Burger King booth—a "Western diet" high in saturated...

Not So Funny? Comedians Have Psychotic Traits

90% of Old Scientific Data May Be Lost

Thanks in part to outdated devices, email addresses

(Newser) - Scientists rely on raw data to reproduce studies and power new research—it's a foundation of the scientific method. But as much as 90% of data is lost within 20 years, according to a new study that puts at least some of the blame on old technology. Researchers emailed...

Jets have power to spew iron and nickel, study finds

(Newser) - For years, astronomers have wondered what exactly black holes spew into our universe—and now they know. Iron and nickel have been found shooting from the relativistic jets of a black hole several times larger than our sun, but the finding is more surprising than it may seem. It shows...

Big Meteor Strikes Way More Common Than Thought

Chelyabinsk-size strike happens every 30 years or so

(Newser) - A meteor strike like the one in Chelyabinsk, Russia , earlier this year might seem like a once in a lifetime event, but a new study in Nature says that isn't the case. Using data from sensors around the world, researchers found that big asteroids have hit Earth's atmosphere...

Breast Milk Protein May Ward Off HIV

That's why babies breastfed by infected moms usually don't catch it

(Newser) - Scientists think they've found a promising new avenue for an HIV treatment in an unlikely place: the breasts of moms. Public health officials have long noticed that infants breastfed by HIV-positive moms rarely contract the virus themselves—even though the virus is definitely inside the milk.

Bogus Study Fools 157 Science Journals

Author says it shows huge flaws in 'open-access' system

(Newser) - An investigation into the world of so-called "open-access" scientific journals has turned up, well, not much scientific credibility. Inspired by colleagues who'd come across some dodgy-looking journals, John Bohannon made up a study describing the anticancer properties of a chemical, then shipped it to 304 open-access journals.
