Why are 20 tons of fossils being stored in the bell tower at the University of California at Berkeley? A look into the world's only paleontological collection that has its own carillon.

Scientists in California report they are using the rapidly reproducing organism to track evolutionary changes. The twist is that the new work on evolution has implications for human cancers.

Ants don't show road rage. In fact, some research shows they rarely get into traffic jams, able to maintain a steady speed even as their numbers swell. Can physics explain it?

Of course they don't, but they do have the genetic machinery to make fingers — something that shows how similar fish are to modern mammals.

NASA's next big space telescope costs $8 billion and is very heavy. New York scientists think they may have found the makings of a cheaper, lighter answer for future space scopes — in a crafts store.

Farmers want tomato varieties that yield more fruit. Consumers want tastier ones. How to resolve that tension? A new genetic toolkit could help growers maximize the best of both worlds.

Bryan Shaw showed it was possible to detect early signs of eye cancer from a family photo album. Now, he and his research team have made an iPhone app.
Monday, October 13, 2014
Jennifer Doudna used to worry that her science wasn't doing anything important. Then some basic research led her team to a discovery that could one day be crucial in healing some genetic diseases.

NASA's MAVEN spacecraft on Sunday night fired its six main rocket engines for 33 minutes. That slowed the probe down enough so it could be captured by the Red Planet's gravity.
