This is SCIENCE FRIDAY, I'm Ira Flatow. Of course we'll be keeping you up to date this hour on the shooting spree that's been going on in Newtown, Connecticut. But first something different. When Alan Alda was 11, he asked one of his teachers: What is a flame? The answer he got back was oxidation. Accurate, yeah, but not very helpful.

Though we hear about them every holiday season in that famous song, chestnuts – whether roasting on an open fire or otherwise – have been noticeably absent from many American tables for decades, thanks to a deadly fungus that decimated the species near half a century ago. But a small army of determined growers have been on a seemingly quixotic quest to put chestnuts back on the American table, and they're just starting to see results.
There are more species of insects than pretty much anything else in the world. And scientists know there are millions they haven't even identified yet. Now, in a tropical rainforest in Panama, a multinational team of scientists has just completed the first ever insect census.
Scott Miller, an entomologist at the Smithsonian who worked on the Panama, shows off one of the species from the survey that's at the National Museum of Natural History's insect zoo in Washington, D.C.

Sputnik 1 just beeped. China's first satellite, launched more than a decade later, simply radioed a communist anthem back to Earth. So far, North Korea's first satellite appears to be less accomplished.
And that shouldn't be a surprise.
Given the history of first orbital space shots, North Korea's apparent struggle with its mission is fairly typical, says David Akin, an associate professor of aerospace engineering at the University of Maryland.
