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.

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.
NASA wants you and your smartphone to help it address global problems. On Sept. 20, the agency announced the International Space Apps Competition asking scientists, engineers, and ordinary citizens to develop apps that use publicly released scientific data to study things like weather-related hazards and other pressing issues.
