An international team of scientists said on Thursday they had recorded sub-atomic particles traveling faster than light

An international team of scientists said on Thursday they had recorded sub-atomic particles that travel faster than light.

A total of 15,000 beams of neutrinos — tiny particles that pervade the cosmos — were fired over a period of 3 years from CERN toward Gran Sasso 730 (500 miles) km away, where they were picked up by giant detectors. Light would have covered the distance in around 2.4 thousandths of a second, but the neutrinos took 60 nanoseconds — or 60 billionths of a second — less than light beams would have taken. “It is a tiny difference,” said Ereditato, who also works at Berne University in Switzerland, “but conceptually it is incredibly important. The finding is so startling that, for the moment, everybody should be very prudent.”

The rover Opportunity as seen from Mars orbit

Opportunity on Endeavour Crater rim

The image to the right was taken by Mars Reconnaissance Orbiter, with the white arrow showing the Mars rover Opportunity perched on the rim of Endeavour Crater.

The rover’s scientists hope that the rocks found on the crater rim, dredged up from deep below when the crater impact occurred, will be the oldest rocks so far touched on the Martian surface, and thus give them a peek at ancient Martian geology.

Philadelphia City Council looks to regulate satellite dish placement

We’re here to help you! The Philadelphia City Council wants to regulate the placement and color of residential satellite dishes.

On Thursday, Clarke is expected to offer final amendments to a bill requiring satellite companies to try to install dishes somewhere other than the front of a building. Roofs, rear or side yards, and backs of buildings all are acceptable, the bill says. The measure would also require some customers to paint their dishes to match the front of their buildings.
