Powerful X-ray images are showing for the first time what happens inside a working battery as it discharges power, and it could lead to improvements for a new type of battery that promises better storage capacity at a lower cost.
In two separate studies, the world’s most powerful X-ray laser has been used to build the first atomic X-ray laser pulse, as well as to superheat and control a clump of 2-million-degree matter. The atomic laser could be used to watch biological molecules at work, while the creation of hot dense matter could be used to understand the processes of nuclear fusion.
Those physicists -- give 'em an inch, and they'll take a mile. Or 20 miles. Groundbreaking science is just beginning to emerge from the Large Hadron Collider, but physicists are already planning their next atom-smasher -- a $6.7 billion linear collider they hope to start building in 2012.
Physicists will meet in Paris this week for a conference on high-energy physics, and they're expected to discuss plans for an old-school linear particle accelerator. The 20-mile-long International Linear Collider (ILC) would be more than 10 times longer than the next-biggest linear accelerator, the SLAC linear accelerator at Stanford, built in 1962.

The call comes in from the control room. Stanford University's particle accelerator-one of the largest machines on Earth-has been shut down because of a failed magnet. This is bad news for the scientists I have traveled across the continent to see: Their experiment was designed to run 24 hours a day and the disruption will cost them reams of precious data. But me, I'm thrilled. Normally, the innards of the radiation-spewing accelerator are off-limits. But idle, it poses no danger.
