Surgeons need rest days, weekends and vacations. But when they come back to work after a break, do they come back refreshed — or rusty?
Executions are carried out by people. When things go wrong, those involved experience stressful, chaotic scenes. And even when they go right, it can take a lasting toll.
When crops are surrounded by high levels of carbon dioxide, they produce more. But those crops have lower concentrations of some crucial nutrients, which could increase malnutrition in the future.
Andrea Turkalo spent 22 years in central Africa, studying rare forest elephants. Then civil war forced her to flee — and poachers killed many of the elephants she'd shared a life with.
Stanford says it will its divest holdings in coal companies over climate change concerns. It's the most prominent of the roughly one dozen colleges that have decided to sell off fossil fuel holdings.
DNA's instructions are written in a code of four molecular "letters," labeled A, C, T and G. For the first time, researchers have created and inserted two brand-new letters into a living cell.
Why is it that in thousands of portraits done all over the world, artists emphasize the left side of the subject's face? There's a bias here, and it's hiding in our brains.
Noah Shaw was diagnosed with a potentially fatal cancer when he was just 4 months old. That didn't shake his father's faith in God. But it did drive him to try to invent an early cancer test.
A new U.S. government report tells an unambiguous story: The planet is warming, climate change is driven primarily by people and it's already affecting Americans, through more frequent or intense heat waves, downpours and, in some regions, floods or droughts.
One chapter of the White House's new climate report focuses on the serious impact climate change has on human health — everything from heat-related illnesses to increased allergies and asthma due to changes in growing seasons and air quality. Melissa Block speaks with Brian Stone, director of the Urban Climate Lab at Georgia Institute of Technology, about the public health effects of climate change.
The National Climate Assessment report indicates that the increasingly erratic weather resulting from global warming has already lead to more flooding, wildfires and drought across the U.S. The report is rich in data about the cause and effects of climate change, just as past reports have been. So why has the public and political response to these dire warnings been so half-hearted? Robert Siegel talks to Bill McKibben, author of Oil and Home: The Education of an Unlikely Activist, about it.
Cotton balls laced with insecticide just might be the answer to a parasitic fly that has been killing off young finches in the Ecuadorian islands since 1997.
Chemistry is complicated; that includes ingredients in artificially flavored fizzy drinks. Soda makers bowed to pressure to drop brominated vegetable oil, but its safety hasn't been very well studied.
For decades, the speed of racehorses and dogs has stagnated. But humans keep getting faster. On the 60th anniversary of the first time a human ran a mile in under four minutes, we ponder why.
The parents of a young boy made a terrible discovery while looking through photographs they had taken of him as a baby. They noticed a white dot where a black pupil should have been.
Thanks to upwelling, an influx of marine and wildlife is taking place in one of the world's largest underwater canyons in California.
Adelie penguins, which breed in huge colonies on the rocky Antarctic Peninsula, harbor a version of the avian influenza virus. But this strain doesn't make humans or the birds sick.
The U.S. Geological Survey and its state counterpart issued a joint statement saying magnitude 3.0 temblors had increased by 50 percent since October.
Germany's famous Max Planck Society has opened a brain research institute in Jupiter, Fla. It's another move in the international competition to attract the best brain researchers.
Several factors are straining lime production in Mexico from heavy rains to a disease infecting trees. But criminal gangs are adding to the high prices by stealing from orchards and hijacking trucks.
