During astronaut Scott Kelly's year in space, scientists will compare his physiology with that of his twin brother, Mark, to study the effect of prolonged space flight on the human body.
An official investigation into an accident last February at the Waste Isolation Pilot Plant has concluded that cat litter is the culprit. Organic material in the litter caused a drum to burst.
The shrinking of ice at the ocean's edge in the West Antarctic has increased by 70 percent over the past decade, an analysis of satellite images suggests.
Writer Gabrielle Glaser challenges the usefulness of Alcoholics Anonymous in April's issue of The Atlantic. The program's tenets aren't based in science, she says, and other options may work better.
Colorado's food and ag industries have been growing two to four times faster than the state's economy overall. Economists are getting ever more hopeful about cornering the market on ag innovation.
Many people have worried that Ebola could evolve into a more deadly virus — or start spreading through the air. A study published Thursday alleviates these concerns.
A single genetic mutation might decide who ends up in bed with the sniffles and who heads to the hospital, because it shuts down immune system molecules called interferons.
In South Florida, the world's two most destructive termite species could be mating because of climate change. Researchers say if the hybrids colonize, they could pose an even greater economic threat.
When malaria parasites infect blood, they manufacture odor molecules that smell sweet to mosquitoes, scientists report. So how do these odors get from the bloodstream to the insects?
Six years ago, husband-and-wife scientists used gene therapy to cure colorblindness in monkeys. Now they're trying to make it work for the millions of people with faulty color vision.
Researchers were surprised by what they found when they sandwiched a drop of water between two layers of an unusual two-dimensional material called graphene.
Researchers in Colombia have created new types of beans that can withstand high heat. Many of these "heat-beater" beans resulted from a unique marriage, 20 years ago, of tradition and technology.
Figuring out the penalty for not signing up for health insurance is just one complication. Tax filers who made more money last year than they anticipated may have to pay back some of their subsidy.
A new coating makes ketchup slide out of the bottle and toothpaste slip out of a tube, right down to the last drop. So why not put the slick surface on an Ebola suit so the virus doesn't stick?
Current tests require growing anthrax in the lab, which isn't the best option for labs in Afghanistan. So engineers have come up with a credit-card-sized test that could make the world a safer place.
Engineers have come up with a credit-card-sized test for the presence of anthrax bacteria. They believe the new test will make it harder for terrorists to get their hands on the deadly bacteria.
A respected scientific group says that glyphosate, also known as Roundup, is "probably carcinogenic to humans." Yet the actual risks — which are mainly to farmers, not consumers — remain uncertain.
Should the government recommend lean meat as part of a healthy diet? That's emerged as a political flashpoint. The panel working on federal guidelines says the evidence on lean meat is muddled.
Early efforts to test legal marijuana are finding that it's got lots of buzzworthy THC. But it can also have fungus, chemical residue and bacteria. What that means for health and safety isn't clear.
For some people who discover a sudden drop in their investments, social science research offers a surprising explanation. When a hedge fund manager gets divorced, they underperform by 7.4 percent.
