Facebook to showcase new look for newsfeed March 7

(Reuters) - Facebook Inc (FB.O) will unveil a new look for its popular "newsfeed" next week, the latest move by the Web company to revamp key elements of its 1 billion member social network.

Facebook will showcase the newsfeed makeover at a media event on March 7 at its Menlo Park, California headquarters, the company said in an emailed invitation to reporters on Friday.

The event will be Facebook's second high-profile product event this year, following the rollout of its social search feature in January.

Facebook's newsfeed, which displays an ever-changing stream of the photos, videos and comments uploaded from a user's network of friends, is one of the three "pillars" of the service, along with search and user profiles, Chief Executive Mark Zuckerberg has said.

Tomb Raider firm denies pressure to include more violence..

But Livingstone, who received a CBE in the New Year honours list, denied the success of shooter games such as Call of Duty and Grand Theft Auto had influenced the game's developers to include more fighting scenes.

U.S. May Face Inevitable Nuclear Power Exit.

In a 2012 report, the Obama administration announced that it was "jumpstarting" the nuclear industry. Because of the industry's long history of permitting problems, cost overruns, and construction delays, financial markets have been wary of backing new nuclear construction for decades. The supposed "nuclear renaissance" ballyhooed in the first decade of this century never materialized. And then came Fukushima, a disaster that pushed countries around the world to ask: Should nuclear power be part of the energy future? In the third and final issue in a series focused on nuclear exits, the Bulletin of the Atomic Scientists, published by SAGE, turns its attention to the United States and looks at whether the country's business-as-usual approach may yet lead to a nuclear phase-out for economic reasons.
