Vicious storms smacked the Deep South and toppled trees like dominoes as tornadoes howled through towns, tossing a mobile home in Alabama nearly a quarter of a mile across a state highway, killing the man inside.

Combined with fatalities in Arkansas and Oklahoma, the death toll had risen to 10 by early Saturday — the deadliest storm of the season so far.

Nokia Corp. on Tuesday launched its first smartphones to run on the updated Symbian software with new icons, enhancements and a faster browser.

Kindergarten classes are supplementing crayons, finger paints and flashcards with iPads, a development that excites supporters but that detractors worry is wasted on pupils too young to appreciate the expense.

Japan raised the severity level of the crisis at its crippled nuclear plant Tuesday to rank it on par with the 1986 Chernobyl disaster, citing cumulative radiation leaks that have contaminated the air, tap water, vegetables and seawater.

Japanese nuclear regulators said the rating was being raised from 5 to 7 — the highest level on an international scale overseen by the International Atomic Energy Agency — after new assessments of radiation leaks from the Fukushima Dai-ichi plant since it was disabled by the March 11 tsunami.

Prime Minister Naoto Kan paid another visit to Japan's tsunami-devastated coast Sunday, promising officials in a fishing-dependent city that his government will do whatever it can to help.

Kan visited Ishinomaki, a coastal city of 163,000 people in Miyagi, one of the prefectures (states) hardest-hit by the March 11 earthquake and tsunami that killed as many as 25,000 people, destroyed miles of coastline and left tens of thousands homeless.

Eric Clapton fulfilled his childhood fantasy as he took a turn on the jazz side, collaborating with Wynton Marsalis and the Jazz at Lincoln Center Orchestra for a little bit of swing at the orchestra's annual gala benefit.

"I've never done anything like this in my life before," said Clapton during Thursday's concert, which saw the Rock and Hall of Famer use his guitar skills to play jazz classics like "Joe Turner's Blues," "Corrine, Corrina" and "Ice Cream."

A new, ultra-fast wireless Internet network is threatening to overpower GPS signals across the U.S. and interfere with everything from airplanes to police cars to consumer navigation devices.

The problem stems from a recent government decision to let a Virginia company called LightSquared build a nationwide broadband network using airwaves next to those used for GPS. Manufacturers of GPS equipment warn that strong signals from the planned network could jam existing navigation systems.
