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.

The globe warms, and the Arctic starts to burn. If warming causes fires that release carbon dioxide, the primary greenhouse gas, will this accelerate further warming? A new study measures carbon releases from the largest tundra fire in North America.

New instruments are giving a better view of how those astonishingly strong lightning bolts form inside clouds – and we are also getting a better picture of the many ways that lightning can harm us.

Humans and cats have enjoyed each other’s company for millennia, but scientists have discovered some troubling secrets of free-roaming felines that have wildlife and health experts worried. A new study reveals what free-roaming cats do all day, and The Why Files investigates some implications of their outdoor habits.

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?

With three nuclear reactors and three pools of spent fuel teetering on the edge of meltdown, Japanese technicians struggled to throttle the nuclear demons after the gigantic tsunami. Is Fukushima closer to Chernobyl or Three Mile Island? How will the disaster affect plans for a renaissance of nuclear power?

After earthquakes caused horrific tsunamis in Sumatra and Japan, we wonder where tsunamis get their power, how warning systems work, and what’s left after the cataclysm.

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.

Are extreme heat, wicked cyclones and record rainfalls signs of climate change, or just more changes in the weather? Will warming eliminate record cold days? Will hurricanes get bigger?
