Denial of science, science of denial Tobacco and cancer. CFCs and ozone. Vaccines and autism. And evolution through natural selection, acid rain and global warming. Why do the facts get lost in a cacophony of argument, falsehood and outright denial? A conference looks at why the media get taken for a ride, and how they can improve.

Should “wastewater” be wasted?

Population growth, climate change and development are all focusing attention on water shortages. Theoretically, water can be recycled forever, but can we possibly clean sewage to make it drinkable? Yes, and a number of projects around the country are doing exactly that. Bottoms up!

Flying robots

Compared to regular airplanes, radio-controlled craft are safer, cheaper, and easier to use for observing wildlife and environmental conditions. Where are these robots being used? What are they finding? And as prices continue to fall, what stands in the way of much broader use?

Amphibian anxiety

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.

Civil war: Changing a stuck mind

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.

Bats under attack

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?

I robot. Aye science!

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.

Methane on the menu in the Gulf of Mexico?

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?

Life in the oceans

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?

Biofuel advance

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.
