Doing it from the inside out, knocking away the most-closely-held, innermost electrons first, is an even rarer feat. But the brilliant X-ray pulses of the Linac Coherent Light Source have done just that, in the successful first test of the unprecedented X-ray laser with its first scientific instrument. The result demonstrates the machine's unique capabilities -with the world's brightest and shortest X-ray laser pulses -and marks the first of two milestones in readiness for the launch of LCLS scientific user experiments this October. http://www.physorg.com/news172503425.html Physics Fri, 18 Sep 2009 15:00:04 EST news172503425 Thanks to a new analytical method employed by researchers at the University of Delaware, scientists can now pinpoint, at the millisecond level, what happens as harmful environmental contaminants such as arsenic begin to react with soil and water under various conditions. http://www.physorg.com/news172255125.html Chemistry Tue, 15 Sep 2009 17:39:14 EST news172255125 (PhysOrg.com) -- John Spence, a physicist at Arizona State University, is a longtime user of the Advanced Light Source at Lawrence Berkeley National Laboratory, where he has contributed to major advances in lensless imaging.
