A wide swath of the Middle East suffered Internet outages after two undersea cables in the Mediterranean were damaged, government officials and Internet service providers said. TeleGeography, a U.S. research group that tracks submarine cables around the world, said the severed lines account for 75% of the capacity connecting the Middle East to Europe. The disruption could last a week or more. It was not clear what severed the cables.

Electronic voting was widely embraced -- with the help of the federal government -- as the cure for inaccuracies in vote counting that roiled the 2000 presidential election. But eight years later, the fix has spawned a new round of bitter controversy. Uncertainty, legal challenges and, in some cases, chaos are gripping voting offices as they contend with allegations that the electronic machines are ridden with defects and vulnerable to manipulation.

Federal inspectors are investigating the failure of an emergency generator at the San Onofre Nuclear Generating Station during three tests in late December. The diesel generator is one of two that provide electricity to safety systems in the event of a power outage at the plant. Emergency generators are tested monthly. Inspectors from the U.S. Nuclear Regulatory Commission arrived at San Onofre on Tuesday and will spend several days looking at what caused the failure and how plant managers responded.

Plagued by troublesome fuel sensors in the space shuttle's main propellant tanks, NASA officials Sunday decided to postpone the launch of Atlantis until Jan. 2 at the earliest. For the second time in two launch attempts last week, at least one of the four engine cutoff sensors failed when technicians were fueling the craft on its launch pad. Two sensors failed during fueling Thursday, and a third failed while the tank was being emptied.

NASA called off Thursday's launch of the space shuttle Atlantis after a pair of fuel gauges in its big external tank failed to work properly, a recurring problem since the 2003 Columbia disaster. Shuttle managers said the next launch attempt would be no earlier than Saturday. Preliminary indications were that the problem might be with an open circuit rather than the gauges themselves -- perhaps a spliced line or a bad connector -- which would be easier to fix.

An electrical breakdown snarled traffic on the Northeast rail corridor for hours, delaying trains arriving at New York's Penn Station from Philadelphia and Boston. Damage to overhead wires halted a passenger train about 8:30 a.m., initially blocking New Jersey Transit service and stranding passengers on one northbound train for nearly 2 1/2 hours.

NASA managers have extended the mission of space shuttle Discovery by a day so that the astronauts can take a closer look at a problem discovered over the weekend with the solar arrays powering the International Space Station. The decision to perform what the space agency called "exploratory surgery" was made Monday after spacewalking astronauts from Discovery found what appeared to be metal shavings inside a joint that rotates to allow the solar panels to track the sun.

Last week, the Food and Drug Administration and heart device maker Medtronic told doctors to stop using a particular component -- the wire lead -- of Medtronic's latest generation of implanted heart defibrillators. Cardiologist Dr. William Maisel, a consultant to the FDA, explains what these devices do and what went wrong. What are these implantable heart devices? Implantable heart devices come in two types. The more common device, a pacemaker, is designed for hearts that beat too slowly.

As many as 10,000 Metrolink commuter rail passengers endured delays of up to about 90 minutes Wednesday night because of a breakdown of a train-switching system at Union Station in downtown Los Angeles, officials said. The mechanical problems also delayed four Amtrak trains, carrying about 950 passengers to and from Los Angeles, for more than an hour each. Denise Tyrrell, a spokeswoman for Metrolink, said the switching system breakdown occurred at 4:50 p.m.

Communications equipment failed at a regional air-traffic control center, shutting down all airline traffic within 250 miles of Memphis and causing a ripple effect across the country that grounded dozens of passenger and cargo flights. The problem started when a major telephone line to the Memphis center went out. The Federal Aviation Administration said air-traffic control operations were back to normal about three hours later.
