While traffic jams are a common occurrence on our highways, high density traffic has completely different effects for ants traveling on trails. As a new study has found, ants don't have traffic jams. Rather, as ant traffic density increases, the traffic maintains the same average velocity as at low densities. http://www.physorg.com/news157627187.html Biology Mon, 30 Mar 2009 10:20:19 EST news157627187 (AP) -- A recent e-mail from Eastman Kodak Co. didn't lead to a Kodak moment for Vanessa Daniele.

However, the systems proposed so far generally require a much greater energy input than the energy they produce, making them impractical for energy generation. Now, a recently revived system may be able to cheaply generate a small amount of power. http://www.physorg.com/news156596965.html Physics Wed, 18 Mar 2009 12:09:57 EST news156596965 Q. I have a lot of e-mails in separate folders of my Microsoft Outlook program, and I want to take some of them off my Windows XP computer and save them on CDs. How can I do that? http://www.physorg.com/news156066884.html Technology Thu, 12 Mar 2009 08:55:33 EST news156066884 Rapid growth of cancer cells and their frequent divisions have their price: Cancer cells need considerably more energy than healthy cells. Their metabolism runs at full speed and requires large amounts of micronutrients, particularly iron. However, high levels of iron in the cell lead to the production of extremely harmful free radicals. To protect itself from these, the cell inactivates free iron by binding it to what are called iron storage proteins. http://www.physorg.com/news155983349.html Medicine & Health Wed, 11 Mar 2009 09:58:28 EST news155983349 Rights groups called on Google, Yahoo! and Microsoft on Friday not to censor their Web search engines one day next week to help protest cyber censorship. http://www.physorg.com/news155574479.html Technology Fri, 06 Mar 2009 15:08:29 EST news155574479 (PhysOrg.com) -- A new approach to wireless communication will guarantee the reachability of emergency services in a better way.

A research team headed by Hans-Dieter Martin and Wilhelm Stahl at the University of Düsseldorf has now synthesized and characterized one of these carotenoids in the lab. As they report in the journal Angewandte Chemie, this compound is characterized by outstanding antioxidative and photoprotective properties. http://www.physorg.com/news148544053.html Chemistry Mon, 15 Dec 2008 06:14:13 EST news148544053 (PhysOrg.com) -- In a few short months, the Linac Coherent Light Source will start operation as the world's first hard X-ray free electron laser, pushing SLAC National Accelerator Laboratory to the frontier of photon science. Using SLAC's linac to drive a free electron laser, or FEL, the LCLS will generate X-rays an eye-popping 10 billion times brighter than the current cutting-edge technology, while simultaneously providing pulses lasting less than one millionth of one billionth of a second. http://www.physorg.com/news147708604.html Physics Fri, 05 Dec 2008 14:10:04 EST news147708604
