Take a bunch of fast-moving electrons, place them in orbit and then hit them with the shock waves from a solar storm. What do you get? Killer electrons. That's the shocking recipe revealed by ESA's Cluster mission. http://phys.org/news187527709.html Space & Earth Thu, 11 Mar 2010 11:02:12 EST news187527709 Physicians treating patients with shock should consider norepinephrine instead of dopamine as a tool for stabilizing blood pressure, according to an editorial in the March 4, 2010, issue of the New England Journal of Medicine (NEJM). http://phys.org/news186859245.html Medicine & Health Wed, 03 Mar 2010 18:20:01 EST news186859245 Researchers at Albany Medical College are releasing results of a study this week that they say will help refocus the search for new drug targets aimed at preventing or reversing the devastating tissue inflammation that results after heart attack and stroke. http://phys.org/news186584393.html Chemistry Mon, 01 Mar 2010 00:00:06 EST news186584393 A comparison of two strategies for treating severe sepsis or septic shock finds that using lactate levels measured in blood samples showed a similar short-term survival rate compared to a treatment regimen using central venous oxygen saturation measured using a specialized catheter, according to a study in the February 24 issue of JAMA. http://phys.org/news186168640.html Medicine & Health Tue, 23 Feb 2010 17:30:55 EST news186168640 Last week, on Feb. 11th, the Solar Dynamics Observatory (SDO) lifted off from Cape Canaveral on a five-year mission to study the sun. Researchers have called the advanced spacecraft the "crown jewel" of NASA's heliophysics fleet. SDO will beam back IMAX-quality images of solar explosions and peer beneath the stellar surface to see the sun's magnetic dynamo in action. http://phys.org/news185807988.html Space & Earth Fri, 19 Feb 2010 13:20:31 EST news185807988 Treating adults with septic shock with intensive insulin therapy to counter elevated blood glucose levels associated with corticosteroid therapy did not result in a reduced risk of in-hospital death, compared to patients who received conventional insulin therapy, according to a study in the January 27 issue of JAMA. The researchers also found that adding a 2nd corticosteroid to treatment did not significantly reduce the risk of death within the hospital. http://phys.org/news183750472.html Medicine & Health Tue, 26 Jan 2010 18:00:01 EST news183750472 (PhysOrg.com) -- Most people know that diamond is one of the hardest solids on Earth, so strong that it can easily cut through glass and steel. Surprisingly, very little is known about the strength of diamond at extreme conditions. But new research by Lawrence Livermore National Laboratory scientists shows that diamond becomes even stronger during rapid compression. http://phys.org/news183732789.html Physics Tue, 26 Jan 2010 12:53:41 EST news183732789 (PhysOrg.com) -- Police and military forces around the world may soon have a new non-lethal weapon at their hands. Called the Thunder Generator, the device is a cannon that fires shock waves that pass through people and objects. Although the shock waves are harmless, they give people the impression of standing in front of a firing squad, according to the cannon's developers. http://phys.org/news183142646.html Technology Tue, 19 Jan 2010 16:58:04 EST news183142646 A reduction in hospital mortality from severe sepsis and septic shock was associated with participation in the Surviving Sepsis Campaign performance improvement initiative, according to an article published simultaneously in the February issues of Critical Care Medicine and Intensive Care Medicine. http://phys.org/news182602208.html Medicine & Health Wed, 13 Jan 2010 10:50:26 EST news182602208 Marital status plays a significant role in how individuals cope economically with disability and health shocks, according to a working paper by University of British Columbia economists Giovanni Gallipoli and Laura Turner. http://phys.org/news181213250.html Medicine & Health Mon, 28 Dec 2009 09:20:08 EST news181213250 Scientists at VIB and Ghent University in Flanders, Belgium have found an unexpected ally for the treatment of septic shock, the major cause of death in intensive care units. By inducing the release of nitric oxide (NO) gas in mice with septic shock, researchers Anje Cauwels and Peter Brouckaert discovered that the animal's organs showed much less damage, while their chances of survival increased significantly. That's contrary to all expectations, since it is generally assumed that nitric oxide is responsible for the potentially lethal drop in blood pressure in septic shock. http://phys.org/news180096790.html Medicine & Health Tue, 15 Dec 2009 11:20:03 EST news180096790 It's the stuff of a Hollywood disaster epic: A comet plunges from outer space into the Earth's atmosphere, splitting the sky with a devastating shock wave that flattens forests and shakes the countryside. http://phys.org/news179994144.html Space & Earth Mon, 14 Dec 2009 06:23:19 EST news179994144 The Voyager spacecraft are now in the outermost layer of the heliosphere, traveling toward interstellar space - the first man-made spacecraft to travel such a vast distance from Earth. http://phys.org/news177092513.html Space & Earth Tue, 10 Nov 2009 16:40:01 EST news177092513 Living with pain is stressful, but a surprisingly short investment of time in mental training can help you cope. http://phys.org/news177058708.html Medicine & Health Tue, 10 Nov 2009 07:20:02 EST news177058708 Nokia, the world's biggest mobile phone maker, issued on Monday a global recall for 14 million faulty chargers made by a subcontractor this year. http://phys.org/news176969488.html Electronics Mon, 09 Nov 2009 06:12:40 EST news176969488 Patients experiencing septic shock who receive inappropriate therapy may have a fivefold reduction in survival, shows a new study. Researchers from the University of Manitoba, Winnipeg, MB, Canada, retrospectively reviewed the cases of 5,715 patients with septic shock to determine the appropriateness of initial antimicrobial therapy, clinical infection site, and relevant pathogens. http://phys.org/news176623517.html Medicine & Health Thu, 05 Nov 2009 16:10:02 EST news176623517 A team of physicists has directly observed a reverse shock wave of light in a specially tailored structure known as a left-handed metamaterial. Although it was first predicted over forty years ago, this is the first unambiguous experimental demonstration of the effect. The research is reported in Physical Review Letters and highlighted with a Viewpoint in the November 2 issue of Physics. http://phys.org/news176397143.html Physics Mon, 02 Nov 2009 15:14:10 EST news176397143 (PhysOrg.com) -- Like yoga for office drones, cells do have coping strategies for stress. Heat, lack of nutrients, oxygen radicals - all can wreak havoc on the delicate internal components of a cell, potentially damaging it beyond repair. Proteins called HSPs (heat shock proteins) allow cells to survive stress-induced damage. Scientists have long studied how HSPs work in order to harness their therapeutic potential. http://phys.org/news176051015.html Medicine & Health Thu, 29 Oct 2009 16:20:01 EST news176051015 (PhysOrg.com) -- Every month, Sarah Stewart-Mukhopadhyay fires her 20-foot gun in the basement of Harvard's Hoffman Lab, sending shivers through the concrete and steel structure that can be picked up by seismometers upstairs. http://phys.org/news176050830.html Space & Earth Thu, 29 Oct 2009 16:01:07 EST news176050830 After decades of focusing on the management of respiratory failure, circulatory shock and severe infections that lead to extended stays in hospital intensive care units, critical care researchers are increasingly turning attention to what they believe is a treatable complication developed by many who spend days or weeks confined to an ICU bed: debilitating muscle weakness that can linger long after hospital discharge. http://phys.org/news175880057.html Medicine & Health Tue, 27 Oct 2009 16:54:26 EST news175880057 Positive social interactions exist within Drosophila: when in a group, Drosophila flies have better memory than when they are isolated. Thomas Preat's team at the Laboratoire de Neurobiologie (CNRS, France) has recently highlighted this phenomenon through olfactory memory tests. http://phys.org/news175279636.html Biology Tue, 20 Oct 2009 18:00:01 EST news175279636 (PhysOrg.com) -- Locally owned small businesses don't insulate communities from layoffs and closures in bad economic times.
