(PhysOrg.com) -- The Georgia Tech Research Institute (GTRI) demonstrated two cargo container security systems at a recent event sponsored by the U.S. Department of Homeland Security (DHS). http://www.physorg.com/news171564788.html Technology Mon, 07 Sep 2009 18:20:01 EST news171564788 In cancer research, as in most other biomedical sciences, they are playing a key role: living cells, kept in sterile plastic containers with red culture media populating incubators in laboratories around the world. But do researchers always know what is really living in their culture dishes? Under the microscope, different cell lines are almost impossible to distinguish from each other. When these important research objects stop growing without apparent reason - is it because of the manipulations by the scientists or because of an invisible viral or bacterial infection? http://www.physorg.com/news168180807.html Biology Thu, 30 Jul 2009 14:20:04 EST news168180807 Research suggests a new level of regulation for cellular export process by molecules previously assumed to be dedicated to import activities. http://www.physorg.com/news165152678.html Biology Thu, 25 Jun 2009 12:45:06 EST news165152678 (AP) -- Chicago on Wednesday became the first U.S. city to adopt a ban on the sale of baby bottles and sippy cups containing the chemical BPA. http://www.physorg.com/news161505893.html Medicine & Health Thu, 14 May 2009 07:45:36 EST news161505893 In computer simulations, the researchers have demonstrated an approximate cloaking effect created by concentric rings of silicon photonic crystals. The mathematical proof brings scientists a step closer to a practical solution for optical cloaking. http://www.physorg.com/news133613541.html Physics Wed, 25 Jun 2008 11:52:21 EST news133613541
