'Nanoball' batteries could recharge car in minutes - tech - 12 March 2009 - New Scientist

Researchers at MIT have developed a lithium battery that charges 100 times faster than current lithium battery designs. The trick is a cathose made up of tiny balls of lithium iron phosphate, 50 nm in diameter, that speed the lithium ion discharge process. They predict that a cell phone with this type of battery would charge in about 10 seconds, and a hybrid car in about 5 minutes.

Wireless Tasers extend the long arm of the law - tech - 11 March 2009 - New Scientist

The tiny dart shown here being fired from the gun is part of the Taser XREP system which involves a charged dart rather than wires leading back to the gun. As a result, the dart can be shot from a distance of 20 metres, increasing the range of this type of weapon.

Docs implement 3D journals

IBM's research arm in Zurich has developed a way to represent patient data by linking it to a 3D view of the body that is hoped to help doctors in better assessing a patient's status. The system allows doctors to rotate the body and zoom inon regions of interest. These regions are linked by arrows to relevant medical information.

Self-Healing Car Coating Repairs Scratches : Discovery News

University of Mississippi researchers have developed a polyurethane coating that is able to repairs scratches if left in the sun for a few hours. The key is a minuscule amount of chitosan, related to chitin which is found in lobster and crab shells. When the material is scratched, the chitosan reforms its bonds, pulling the polyurethane along. Within an hour the scratch is gone. They are now planning to conduct long-term testing so they can determine if it is commercially viable.

Technique Disables Plutonium's Use in Bombs: Discovery News

Israeli researchers have discovered that by doping plutonium with americium, a waste product from nuclear reactors, the result is a fuel that can burn but requires extensive processing to make it useful for nuclear weapons, with the exception of "dirty bombs".
