‘Anomalies’ discovered in Metro track control circuit
Transportation investigators Wednesday discovered "anomalies" in an essential control circuit of a track where a fatal crash between two Washington subway trains killed nine people. Each section of the transit system’s track contains a circuit that transmits and receives signals that generate speed commands for trains, said Debbie Hersman of the National Transportation Safety Board. She said the circuits are “vital providing information to the operators and the train itself when on automatic.” Investigators found no problems in five of the six circuits on the 740-foot-long stretch of track in the crash area
Egypt shock Italy in Confederations Cup
A 40th-minute header from Mohamed Homos gives Egypt a shock 1-0 Confederations Cup victory over Italy at Ellis Park, Johannesburg, to leave the world champions’ qualification hopes in the balance. Homos — who replaced 35-year-old captain Ahmed Hassan, the country’s most capped player, in the only change to the Egyptian side beaten 4-3 by Brazil — rose powerfully to nod a corner from Mohamed Aboutrika past Italian goalkeeper Gianluigi Buffon. Egypt and Italy are now level on three points in Group B, behind Brazil who have won both their matches, with the Pharoahs favorites to go through to the semifinals.
High-altitude wind machines could power NYC
The wind blowing through the streets of Manhattan couldn’t power the city, but wind machines placed thousands of feet above the city theoretically could. The first rigorous, worldwide study of high-altitude wind power estimates that there is enough wind energy at altitudes of about 1,600 to 40,000 feet to meet global electricity demand a hundred times over.
NASA scrubs Saturday launch of space shuttle Endeavour
A gaseous hydrogen leak on the space shuttle Endeavour forced NASA to cancel Saturday’s planned launch, the space agency said. NASA halted fueling of the shuttle after detecting the leak on a vent line that leads from the ground umbilical carrier plate to the launch pad and to the “flare stack” where vented hydrogen is burned off, the space agency said.
Fantasy features of an Apple tablet
Apple is rumored to be working on something bigger than an iPod Touch, but smaller than a MacBook. Past patent applications filed by the company and whispers from contract manufacturers point to a midsize gadget with a screen of 7 to 8 inches in the works, perhaps scheduled to debut early next year. It’s been variously described as a tablet-like device, a “media pad,” and an iPod Touch on steroids
