This will "ablate" or vaporize a microgram-sized piece of the target, generating a plume of ionized gas or plasma, which will be analyzed by spectrometers to identify the target's constituent elements. Future Mars rovers, however, will be able to do even more. Researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), in collaboration with Applied Spectra, Inc., have developed an advanced version of this laser technology that can also analyze a target's constituent isotopes. This expanded capability will enable future rovers for the first time to precisely date the geological age of Martian samples. http://phys.org/news249825214.html Space & Earth Thu, 01 Mar 2012 11:53:42 EST news249825214 By combining airborne laser technology, satellite mapping, and ground-based plot surveys, a team of researchers has produced the first large-scale, high-resolution estimates of carbon stocks in remote and fragile Madagascar.

Oftentimes these backups occur as the result of accidents and the resulting investigative work that goes on before cleanup can commence. Such work must be done in order verify what occurred during an accident for both legal and financial reasons, thus, there is little chance of simply doing away with some of them. There does appear to be hope of developing new ways to do that detective work though, as new technology is developed to help speed things along. One of these new technologies involves the use of laser equipped 3D cameras and computer technology, instead of old fashioned photography and legwork. http://phys.org/news244714580.html Technology Mon, 02 Jan 2012 08:16:46 EST news244714580 (PhysOrg.com) -- A research group led by ETH Zurich has now, for the first time, visualized the motion of electrons during a chemical reaction.
