Space station detector finds first clues to 'dark matter'

By CNN's Laura Smith-Spark

Nearly two years after it was sent up to the International Space Station, a giant particle physics detector has provided its first results in the search for the mysterious "dark matter" believed to be a major component of the universe.

The international team running the Alpha Magnetic Spectrometer released its initial findings Wednesday at the European Organization for Nuclear Research, known as CERN, in Switzerland.

The scientists are studying flux in cosmic rays, the charged high-energy particles that permeate space, for evidence of the invisible dark matter particles colliding with each other, leading to what is termed "annihilation."

Scientists: Particles appear to travel faster than light

Scientists in Switzerland say an experiment appears to show that tiny particles traveled faster than the speed of light - a result that would seem to defy the laws of nature.

The physicists say that neutrinos sent 730 kilometers (453.6 miles) underground between laboratories in Switzerland and Italy arrived a fraction of a second sooner than they should have, according to the speed of light.

The report was published Friday by a group of researchers working on the so-called Opera experiment, based at the European Organization for Nuclear Research (CERN) in Switzerland.
