(PhysOrg.com) -- A group of South Korean and American researchers has found studies of possible links between cell phones and brain tumors and other cancers vary in quality, and those suggesting there is little or no risk may have some bias. http://www.physorg.com/news174810947.html Medicine & Health Thu, 15 Oct 2009 07:36:26 EST news174810947 (AP) -- The cost of making phone calls has been dropping rapidly in the last few years. If you want take full advantage of that, you'll need to try some new things, because the phone companies aren't going to thrust savings on you. Here are 10 tips on how to cut the cost of your phone service. http://www.physorg.com/news173552258.html Technology Wed, 30 Sep 2009 18:10:01 EST news173552258 In a recent column, Dianne Dunlap, a customer support engineer specializing in wireless technology for Cisco Systems, gave a thorough breakdown of how to check whether wireless Internet connectivity problems are due to wireless card issues -- and how to fix them. http://www.physorg.com/news170616258.html Technology Fri, 28 Aug 2009 01:30:03 EST news170616258 A remarkable new invention from Tel Aviv University - a network of tiny sensors as small as dewdrops called "Smart Dew" - will foil even the most determined intruder. Scattered outdoors on rocks, fence posts and doorways, or indoors on the floor of a bank, the dewdrops are a completely new and cost-effective system for safeguarding and securing wide swathes of property. http://www.physorg.com/news157288786.html Technology Thu, 26 Mar 2009 12:20:30 EST news157288786 It seems like the ordinary is no longer acceptable when it comes to the ordinary things we attach to our computers these days. For example, I'll bet the computer mouse you are using is at the very least an optical, cordless model. I'm even willing to bet it's one of those sleek, ergonomic models that sport extra buttons that can fire off macros with a simple click. That screen you're staring at is probably a flat panel display that may even be capable of displaying high definition television images. http://www.physorg.com/news157228531.html Electronics Wed, 25 Mar 2009 19:36:08 EST news157228531 New research from Rice University and the University of Oulu in Oulu, Finland, finds that carbon nanotubes could significantly improve the performance of electrical commutators that are common in electric motors and generators. http://www.physorg.com/news155939264.html Nanotechnology Tue, 10 Mar 2009 21:28:08 EST news155939264 Major research initiatives are needed immediately to assess the possibility that using cellular phones may lead to an increased risk of brain tumors, according to an editorial in the November issue of the journal Surgical Neurology, published by Elsevier. http://www.physorg.com/news143712781.html Medicine & Health Mon, 20 Oct 2008 09:13:01 EST news143712781 This all new version has both its hardware and software upgraded.

It is based on a polymer electrolyte, which is - unlike the liquid electrolyte in conventional lithium-ion batteries - not inflammable. A test set-up for redox flow batteries will also be on display at the show. This makes it possible to compare different redox systems in a single test set-up. http://www.physorg.com/news127058927.html Technology Thu, 10 Apr 2008 15:08:47 EST news127058927 Securing evidence at the scene of a crime, measuring faces for medical applications, taking samples during production - three-dimensional images are in demand everywhere.
