(PhysOrg.com) -- A company that makes steel for bearings used in heavy trucks had a big problem. The trucks travel through harsh, perilous environments such as Siberia, and an unexpected bearing failure on a remote stretch could literally put the driver's life in danger. Knowing how long the steel would hold up under those conditions was beyond their ability to predict experimentally, so they turned to specialists at MIT. http://www.physorg.com/news175952830.html Technology Wed, 28 Oct 2009 12:48:04 EST news175952830 (PhysOrg.com) -- Scientists have a long and unsuccessful history of attempting to convert hydrogen to a metal by squeezing it under incredibly high and steady pressures. http://www.physorg.com/news173975824.html Physics Mon, 05 Oct 2009 15:38:07 EST news173975824 (PhysOrg.com) -- For the first time, IBM researchers in Zurich, Switzerland, have taken a 3D image of an individual molecule. Using an atomic force microscope, the researchers constructed a "force map" of pentacene, an organic molecule just 1.4 nanometers long. As the researchers explain, the technique is roughly analogous to how an x-ray machine images bones in the human body by looking through flesh. In this case, the scientists could look through the electron cloud and see the atomic backbone of the molecule. http://www.physorg.com/news170685108.html Nanotechnology Fri, 28 Aug 2009 13:34:27 EST news170685108 Ever since graphene was discovered in 2004, this one-atom thick, super strong, carbon-based electrical conductor has been billed as a "wonder material" that some physicists think could one day replace silicon in computer chips. http://www.physorg.com/news168251755.html Nanotechnology Fri, 31 Jul 2009 09:36:30 EST news168251755 Using devices millionths of a meter in size, physicists at the California Institute of Technology (Caltech) have developed a technique to determine the mass of a single molecule, in real time. http://www.physorg.com/news167490673.html Nanotechnology Wed, 22 Jul 2009 14:11:57 EST news167490673 (PhysOrg.com) -- You do two things at motorway services: fill up one tank and empty another. US chemists have combined refuelling your car and relieving yourself by creating a new catalyst that can extract hydrogen from urine. http://www.physorg.com/news165836803.html Chemistry Fri, 03 Jul 2009 10:47:26 EST news165836803 James Hagman, Ph.D., professor of immunology at National Jewish Health and his colleagues have identified two "molecular motors" that work in opposing directions to control the development of B cells in the immune system. http://www.physorg.com/news165146274.html Medicine & Health Thu, 25 Jun 2009 10:58:21 EST news165146274 (AP) -- The world's largest atom smasher will likely be fired up again in October after scientists have carried out tests and put in place further safety measures to prevent a repeat of the faults that sidelined the $10 billion machine shortly after startup last year, the operator said Saturday. http://www.physorg.com/news164735558.html Physics Sat, 20 Jun 2009 16:53:05 EST news164735558 By creating a model of the active site found in a naturally occurring enzyme, chemists at the University of Illinois have described a catalyst that acts like nature's most pervasive hydrogen processor. http://www.physorg.com/news161868806.html Chemistry Mon, 18 May 2009 12:33:46 EST news161868806 The most abundant material on Earth exhibits some unusual chemical properties when placed under extreme conditions. http://www.physorg.com/news156779157.html Chemistry Fri, 20 Mar 2009 14:46:43 EST news156779157 The enzyme DFPase from the squid Loligo vulgaris, is able to rapidly and efficiently detoxify chemical warfare agents such as Sarin, which was used in the Tokyo subway attacks in 1995. http://www.physorg.com/news152375661.html Chemistry Wed, 28 Jan 2009 14:35:02 EST news152375661 (PhysOrg.com) -- The nuclei of ordinary hydrogen atoms contain only a single proton. If a neutron is added, the hydrogen becomes deuterium. In principle, molecules that contain deuterium in place of hydrogen atoms are chemically identical. However, there can be significant differences. Thus `heavy water`, water with molecules that contain deuterium in place of hydrogen, is toxic because it disrupts highly sensitive biochemical processes in the body and leads to metabolic failure. http://www.physorg.com/news150561487.html Chemistry Wed, 07 Jan 2009 14:38:07 EST news150561487 (PhysOrg.com) -- Solar flares are the most powerful explosions in the solar system. Packing a punch equal to a hundred million hydrogen bombs, they obliterate everything in their immediate vicinity. Not a single atom should remain intact. At least that's how it's supposed to work. http://www.physorg.com/news148570868.html Space & Earth Mon, 15 Dec 2008 13:41:08 EST news148570868 Duke University chemists say they have developed a new way to measure temperature changes inside the body with unprecedented precision by correcting a subtle error in the original theory underlying Magnetic Resonance Imaging (MRI). http://www.physorg.com/news143383004.html Chemistry Thu, 16 Oct 2008 13:36:44 EST news143383004 (PhysOrg.com) -- "Ye canna change the laws of physics!" Scotty warned Captain Kirk on Star Trek.
