The most potent gamma rays, the so-called VHE (very high energy) gamma rays, pack energies a billion times this, or even more. Astronomers think that VHE gamma rays are produced in the environment of the winds or jets of the compact, ultra-dense remnant ashes of massive stars left behind from supernova explosions. http://www.physorg.com/news173104115.html Space & Earth Fri, 25 Sep 2009 13:29:49 EST news173104115 (PhysOrg.com) -- A new research project at Idaho National Laboratory and Argonne National Laboratory will use an innovative approach to learn how to get more use from nuclear fuel. http://www.physorg.com/news173025081.html Physics Thu, 24 Sep 2009 15:50:01 EST news173025081 The National Institute of Standards and Technology has issued a new ruler, and even for an organization that routinely deals in superlatives, it sets some records. Designed to be the most accurate commercially available "meter stick" for the nano world, the new measuring tool -- a calibration standard for X-ray diffraction -- boasts uncertainties below a femtometer. That's 0.000 000 000 000 001 meter, or roughly the size of a neutron. http://www.physorg.com/news172862033.html Nanotechnology Tue, 22 Sep 2009 18:40:01 EST news172862033 (PhysOrg.com) -- A West Virginia high-school student analyzing data from a giant radio telescope has discovered a new astronomical object -- a strange type of neutron star called a rotating radio transient. http://www.physorg.com/news172860368.html Space & Earth Tue, 22 Sep 2009 17:49:46 EST news172860368 (PhysOrg.com) -- Scientists at the Naval Research Laboratory Space Science Division and a team of international researchers have positively identified cosmic sources of gamma-ray emissions through the discovery of 16 pulsating neutron stars. http://www.physorg.com/news172858253.html Space & Earth Tue, 22 Sep 2009 17:12:47 EST news172858253 (PhysOrg.com) -- A dramatic new vista of the center of the Milky Way galaxy from NASA's Chandra X-ray Observatory exposes new levels of the complexity and intrigue in the Galactic center.

These markers, called isotopes, can tell scientists where the molecules that compose a substance are from, where they traveled, and what happened to them along the way. But doing these analyses has been complex and costly. Now, Stanford chemists have developed a new method to make isotopic analysis easier and less expensive. http://www.physorg.com/news165515832.html Chemistry Mon, 29 Jun 2009 18:40:01 EST news165515832 (PhysOrg.com) -- A new calculation clarifies the complicated relationship between protons and neutrons in the atomic nucleus and offers a fascinating resolution of the famous NuTeV Anomaly. http://www.physorg.com/news165500651.html Physics Mon, 29 Jun 2009 13:25:10 EST news165500651 (PhysOrg.com) -- NASA's long-lived Mars Odyssey spacecraft has completed an eight-month adjustment of its orbit, positioning itself to look down at the day side of the planet in mid-afternoon instead of late afternoon. http://www.physorg.com/news164909297.html Space & Earth Mon, 22 Jun 2009 17:09:00 EST news164909297 Astronomers at the University of California, Santa Cruz, have developed a new technique to determine the ages of millisecond pulsars, the fastest-spinning stars in the universe. http://www.physorg.com/news163781369.html Space & Earth Tue, 09 Jun 2009 15:50:13 EST news163781369
