China burns nearly as much coal as the rest of the world combined--and has 300 more coal plants in the works. But China also leads the world in solar panel exports and wind farms, and has a national climate change policy in place. Is the U.S. falling behind on climate? Ira Flatow and guests discuss how the world is tackling global warming--with or without us--and what it might take to change the climate on Capitol Hill.
To the long and growing list of risk factors known to increase the risk of obesity, scientists recently added a new one: scarcity.
People given subtle cues that they may have to confront harsh conditions in the near future choose to eat higher-calorie food than they might do otherwise, a response that researchers believe is shaped by the long hand of evolution.
Now for a surprising find from the insect world. The dung beetle, that insect known for sculpting little balls of animal feces that they roll around and later feast on. Well, it turns out that these beetles have a built-in cosmic GPS that helps them navigate around. Dung beetles use light - listen to this - use light from the Milky Way to orient themselves at night. It's all in a paper published earlier this month in the journal Current Biology.

The human neck is a delicate stem. Torque it a bit too much, and the carotid and vertebral arteries can rip, causing deadly strokes.

The grim headlines just keep coming. This week it's former NFL kicker Tom Dempsey. Age 66, Dempsey suffers from dementia. During his football career he endured three diagnosed concussions and, almost certainly, several undiagnosed ones. As The New York Times notes, his neurologist was "astonished by the amount of damage" visible on Dempsey's brain scans.
Arguments are often heard against big (read: expensive) scientific projects, especially those without an immediate pay off. "Why spend so much money building this machine or spacecraft, when there are so many pressing social issues we must deal with?"
