One of the largest panoramic images ever taken with Hubble's cameras has been released to celebrate the 17th anniversary of the launch and deployment of the NASA/ESA Hubble Space Telescope. The image shows a 50 light-year-wide view of the tumultuous central region of the Carina Nebula where a maelstrom of star birth -- and death -- is taking place.

Findings described in a new study by Stanford scientists may be the first step toward a major revolution in human regenerative medicine -- a future where advanced organ damage can be repaired by the body itself. Scientists show that a human evolutionary ancestor, the sea squirt, can correct abnormalities over a series of generations, suggesting that a similar regenerative process might be possible in people.
