Light robs galaxy of star-making gas

Sat, 2014-12-13 11:00
Stars form from clouds of hydrogen and other gases. Astronomers have found the light from newborn stars can drive off that gas. That action can starve a galaxy of the ingredients needed to make more stars.

Tiny — but mighty — food-cleanup crews

Wed, 2014-12-10 09:30
Discarded food wastes can turn city spaces into food courts for disease-carrying rats and pigeons. But a new study shows tiny cleanup crews — especially pavement ants — are doing their best to eliminate such wastes. This, in turn, makes cities less attractive to bigger pests.

Climate change brings new neighborhood birds

Tue, 2014-12-09 09:06
Climate change has made winters a little bit warmer. Many bird species are now wintering a lot farther north than they did a few decades ago, a new study finds.

Earth’s most common mineral finally gets a name

Sun, 2014-12-07 12:00
A half-century search for samples of Earth’s most abundant mineral has ended. This stuff forms only deep in the rocky layer surrounding our planet’s core. But scientists found bits of it in a meteorite that fell in 1879. And finally, this bridgmanite gets a name.

Why animals often ‘stand in’ for people

Thu, 2014-12-04 09:27
Rats, birds, fish — even flies and worms — can stand in for people in laboratory testing. This allows scientists to safely evaluate harmful chemicals as well as to identify and test potential new drugs. But such tests will never be a foolproof gauge of effects in people.

How ‘bugs’ in our bellies impact our health

Mon, 2014-12-01 12:59
Gut bacteria can play a powerful role in human health, new studies show. In one, bacteria turned a nutrient in red meat into a chemical that boosts the risk of a heart attack. Another study shows that our genes play a role in whether we are fat or thin, probably by affecting which bacteria prefer to live in our intestines.
