This Week: Reading magma, predicting giant eruptions
In the News: Superbowl or stuporbowl? What's the story on brain damage?
Amphibians are disappearing faster than any other animals. A new study looks at the effects of changes in climate, land use and disease. The picture isn’t pretty, but looking at three threats at once shows the true danger facing frogs, toads, salamanders and their relatives.
After six decades, the Palestine-Israel stalemate seems hopeless. But could that very hopelessness be blocking a solution? A new study of people on both sides of the struggle shows that learning about the peaceful resolution of other intractable conflicts can increase their willingness to compromise – a key to peace.
White nose syndrome has killed a million bats in the eastern U.S., and spread to Nova Scotia, South Carolina and Tennessee. Why is the fungus deadly here, but not in Europe? Can quarantines, anti-fungals or heated bat houses help our bats survive the onslaught?
Military technology supports atmospheric and ocean science! 1: a robot sub smart enough to find stuff in the deep ocean 2: a metal fish glides for weeks under the ice 3: an electric sinker-bobber that never needs recharging 4: a research jet that flies miles above airliners.
The BP spill released about 160,000 tons of methane into the Gulf of Mexico, but a new study shows that it was eaten by friendly bacteria. The seabed contains an astonishing amount of methane, a strong greenhouse gas. So can bacteria reduce the global warming hazard of massive methane releases?
Most of our planet is ocean, and now we have a better idea of what lives there. Marine creatures are much weirder than those on land. The Census of Marine Life looked at salmon migration, Arctic animals, and the uncountable variety of bacteria in the sea. Want to take a look?
Ethanol in gasoline now comes mainly from corn, a food crop. Cellulose, found in crop wastes, wood and switchgrass, could be a great source of ethanol, if only the yeast that makes ethanol could digest cellulose. A new genetic alteration forced yeast to break down cellulose, and then convert it into ethanol.
Urban farms are sprouting in the most unlikely places. Advocates say they help with nutrition, obesity and job training. They build community and help immigrants assimilate, cut energy usage, and cool the planet. But does the reality match the claims? Food is flowing, but what’s new with farming in the city?
We need more electricity. More alternative energy. Less greenhouse warming, and better ways to manage our power supply. Can the electric grid meet multiple challenges and help us survive prosperity? What good are smart meters? And what is this going to cost?
When big tech goes bad, we ask: How do engineers design fail-safe mechanisms for nuclear weapons, radioactive waste, spaceships?
