Small colonies of swimming magnetic particles can self-assemble into micro-machines that can manipulate other particles, scientists report.
The particles can be remotely controlled to grasp and move other objects, which could enable precise and delicate fabrication processes that were previously not possible with machines.
The Department of Energy is getting a 10-petaflop supercomputer to help scientists design efficient electric car batteries, understand climate change and unravel cosmic mysteries.
The IBM-built system, nicknamed "Mira," will be operational at Argonne National Laboratory next year. At 10 quadrillion calculations per second, it will be twice as fast as today's fastest supercomputer and 20 times faster than Argonne's current model. If every person in the United States performed one calculation every second, it would take almost a year for them to do as many calculations as Mira will do in one second, according to IBM.
China is moving factories, banning taxis, and even modifying the weather to clean up its dirty air in time for the 2008 Summer Olympics

At this time next year, the world's finest athletes will converge in Beijing for the 2008 Olympics. They will sprint, leap, and toss their way to gold-that is, if they can get a breath of clean air. China has some of the worst pollution in the world, and bad air kills 400,000 Chinese annually [see "China's Green Evolution." In anticipation of the Olympics, Beijing has launched a massive cleanup. Some 200 factories in the area will be relocated.
A house made of Styrofoam?
Sounds flimsy. But spray it with a new brick-like concoction called Grancrete, and it’s virtually indestructible. Invented by scientists at Argonne National Laboratory near Chicago and builders at Casa Grande, a construction firm
