A study looking at why clouds make the air near them glow more brightly suggests climate models may need to be revised.
Atmospheric scientists already account for the brighter air close to clouds, thanks to a 2007 study by Ilan Koren and his colleagues at the Weizmann Institute of Science in Rehovot, Israel. The team showed that cloud droplets, attached to dust and smoke particles, float in a halo kilometres wide around clouds, bouncing sunlight back out of the atmosphere. Seen from a satellite, that means air close to clouds looks brighter.

Researchers could cut the use of animals in their experiments by changing the way they analyze their results, according to a study by scientists based in Germany and the United States.
In a typical animal experiment, researchers will try to standardize factors such as the animals’ genetic backgrounds and laboratory conditions to make it as easy as possible for other researchers to reproduce their results later. Now, a team led by Hanno Würbel at the Justus-Liebig-University in Giessen, Germany, has reanalyzed a study of mouse behaviour by taking such genetic and environmental variations into account, and they got fewer spurious results, or false positives, than the initial study.

A French-Russian mathematician has won the Abel Prize today for his work on advanced forms of geometry.
The winner of the 6 million Norwegian kroner (US$920,000) prize, Mikhail Leonidovich Gromov, has held a permanent appointment at the Institute of Advanced Scientific Studies (IHES) outside Paris since 1982.

David Osterbur spent a decade pursuing an academic science career before tiring of the “never-ending cycle” of unfunded grant applications, he says. When his wife, like him a developmental biologist, accepted a job offer in Massachusetts, he took advantage of the change in location to weigh a change in career. He was considering a career in public health so he could continue using his science background, when his wife suggested he become a science librarian. “I had always enjoyed being in the library. In graduate school, people would always come to me when they couldn’t find something,” he says.
