Scientists Question Faster-Than-Light Neutrinos

Last night, in response to a worldwide surge in interest, the OPERA experiment released a paper that describes the experiments that appear to show neutrinos traveling faster than the speed of light. And today, CERN broadcast a live seminar in which one of the work’s authors described the content of the paper. Both of those emphasized the point of our initial coverage: figuring out whether anything is traveling beyond the speed of light requires incredibly accurate measurements of time and distance, and the OPERA team has made an extensive effort to make its work as accurate as possible.

Can Neutrinos Move Faster Than Light?

If it’s true, it will mark the biggest discovery in physics in the past half-century: Elusive, nearly massive subatomic particles called neutrinos appear to travel just faster than light, a team of physicists in Europe reports. If so, the observation would wreck Einstein’s theory of special relativity, which demands that nothing can travel faster than light.

Unique Gait Can Give Crooks Away

The way we walk could be used as an accurate way of identifying us, according to an international team of bioengineers who analyzed the foot pressure patterns created by 104 subjects. They found they were able to identify individuals with a 99.6 percent accuracy.

Astronomers Plead for Space Telescope’s Life

NASA officials and leading astronomers say the James Webb Space Telescope, successor to the Hubble Space Telescope, should still fly despite mounting criticism, cost increases, and disagreements within the astronomy community.
