Using EMP To Punch Holes In Steel 165

angrytuna writes "The Economist is running a story about a group of researchers at the Fraunhofer Institute for Machine Tools and Forming Technology in Chemnitz, Germany, who've found a way to use an EMP device to shape and punch holes through steel. The process enjoys advantages over both lasers, which take more time to bore the hole (0.2 vs. 1.4 seconds), and by metal presses, which can leave burrs that must be removed by hand."

Research at Northwestern University has shown that a combination of nanotechnology and biology may enable damaged tissues and organs to heal themselves. In a dramatic demonstration of what nanotechnology might achieve in regenerative medicine, paralyzed lab mice with spinal cord injuries have regained the ability to use their hind legs six weeks after a simple injection of a purpose-designed nanomaterial.

An anonymous reader writes "A new device devised by Amsterdam graduate student Melanie Rieback is designed to serve as a portable firewall for RFID tags. The portable battery-powered RFID Guardian uses an access control list to filter RFID queries, blocking queries that aren't approved. Rieback, who is also known for being the first researcher to develop a proof of concept RFID virus, hopes to offer version 3.0 of the RFID Guardian to the public at cost."

According to the Government Accountability Office, there are now some 48,000 employees of private military companies in Iraq. These not-quite G.I. Joes, working for Blackwater and other major U.S. firms, can clear in a month what some active-duty soldiers make in a year. "We got 126,000 contractors over there, some of them making more than the secretary of Defense," said House Defense Appropriations Subcommittee Chairman John Murtha.
