"T-rays" may make X-rays obsolete as a means of detecting bombs on terrorists or illegal drugs on traffickers, among other uses, contends a Texas A&M physicist who is helping lay the theoretical groundwork to make the concept a reality. In addition to being more revealing than X-rays in some situations, T-rays do not have the cumulative possible harmful effects. http://www.physorg.com/news180352656.html Physics Fri, 18 Dec 2009 10:30:01 EST news180352656 (PhysOrg.com) -- Evidence for a thin veil of carbon has been found on the neutron star in the Cassiopeia A supernova remnant.

Although the galaxy is over 100,000 light-years in size, nearly 10% of all of its molecular gas lies in the CMZ. Astronomers know that regions of dense gas and dust tend to produce new stars as the material coalesces and heats up under the influence of gravity. http://www.physorg.com/news170687664.html Space & Earth Fri, 28 Aug 2009 14:15:25 EST news170687664 GOES-14, formerly GOES-O, has achieved another significant milestone with the release of the first formal Solar Image from the Solar X-Ray Imager (SXI). http://www.physorg.com/news169819906.html Space & Earth Tue, 18 Aug 2009 13:50:01 EST news169819906 (PhysOrg.com) -- A study published in the July 17 issue of the journal Science details how sandfish -- small lizards with smooth scales -- move rapidly underground through desert sand.

The unsightly infection was caused by the varicella zoster virus and was responsible for nearly 4 million cases each year, according to the Centers for Disease Control (CDC), until a vaccine introduced in 1995 reduced that number by 83 percent. Yet, if you were among those that suffered from chicken pox, the varicella zoster virus may still be present in your body and could lead to serious (and irreversible) oral health problems such as herpes-type lesions and severe bone damage to the jaws. http://www.physorg.com/news154202240.html Medicine & Health Wed, 18 Feb 2009 17:58:53 EST news154202240
