Teaching people game theory is good. Making them live it is even better, says UCLA professor Peter Nonacs. On test day for my Behavioral Ecology class at UCLA, I walked into the classroom bearing an impossibly difficult exam. Rather than being neatly arranged in alternate rows with pen or pencil in hand, my students sat in one tight group, with notes and books and laptops open and available. They

Superhero-Style Spacesuits Could Provide Vital Compression For Astronauts This new Spiderman-style suit may not win astronauts a spot in the fashion hall of fame, but it could help keep their bones intact during long spaceflights. Described in a new paper, prototype tests of the Gravity Loading Countermeasure Skinsuit, being developed by a research team at MIT’s Man-Vehicle Laboratory, show that t
In a new study, researchers report that bumblebees were able to figure out the most efficient routes among several computer-controlled "flowers," quickly solving a complex problem that even stumps supercomputers. Queen Mary, University of London We already know bees are pretty good at facial recognition, and researchers have shown they can also be effective air-quality monitors. Here’s one more re
My hand is like a red-hot poker to the liquid nitrogen, but an insulating layer of nitrogen gas forms- a phenomenon known as the Leiden-frost effect- keeping my hand safe and warm for a fraction of a second.

The Hayabusa spacecraft landed in the Australian outback on June 13, after a seven-year space journey. It is the hope of JAXA, Japan’s space agency, that the capsule Hayabusa is carrying contains a sample taken from asteroid Itokawa. If so, this will be the first sample of asteroid material ever returned to Earth by a space mission. Now, the process of opening the capsule to see what’s inside has
Japan Plans a Moon Base by 2020, Built by Robots for Robots America may have eighty-sixed its moon base ambitions, but the Japanese have no plans to let perfectly good lunar real estate go to waste. An ambitious $2.2 billion project in the works at JAXA, the Japanese space agency, plans to put humanoid robots on the moon by 2015, and now official backing from the Prime Minister’s office says the J
