Cray employees put the finishing touches on Titan at the Department of Energy's Oak Ridge National Laboratory in Tennessee. The supercomputer may be the world's fastest. It's designed to do 20 petaflops — or 20,000 trillion calculations — each second. It consumes enough electricity to power a small city of 9,000 people.
The world's fastest supercomputers have come back to the U.S. In June, the title was claimed by a machine named Sequoia at Lawrence Livermore Labs. Monday, at the Department of Energy's Oak Ridge National Laboratory, what could be an even faster computer comes online. It's called Titan and it would not have been possible were it not for the massive market for video games.
Just some of the food labels a Danish government group is evaluating.
Wherever you look these days, it seems labels that strive to send a message about our food are on the table. In California, there's a vote coming up on whether genetically modified foods should be labeled. A few weeks ago, the U.S. Federal Trade Commission updated its guidelines for "green" labeling.

Science and religion alike grapple with some of our deepest questions: What is the purpose of life? Why is the natural world just so? Why does the biological world strike us as so exquisitely designed?
Here are a few reasons government forecasters at the National Hurricane Center and emergency management officials are so concerned about Sandy:
1. Sandy is one of the largest hurricanes ever to strike the U.S. Sandy's winds cover an area of more than 1,000 miles in diameter. That's enormous by hurricane standards. So instead of affecting an area a couple of hundred miles across, Sandy will cut a huge swath. That means many millions of people are probably going to be exposed to high winds, heavy rains, and, for those on the coast, powerful storm surge.
It is autumn, and where I live the leaves are peaking; there is a riot of them everywhere, narrow ones, broad ones, droopy ones, crunchy ones. Leaves come in so many shapes, hues, textures — the closer you look, the more differences you see. Botanists have names for every leaf type, and clumped together, says writer Robert Dunn, they sound like free verse poetry ...
