(PhysOrg.com) -- The creation of long platinum nanowires at the University of Rochester could soon lead to the development of commercially viable fuel cells. http://www.physorg.com/news156003211.html Nanotechnology Wed, 11 Mar 2009 15:14:29 EST news156003211 The experimental drug fampridine (4-aminopyridine) improves walking ability in some individuals with multiple sclerosis (MS). That is the conclusion of a multi-center Phase 3 clinical trial, the results of which were published today in the journal The Lancet. http://www.physorg.com/news154938328.html Medicine & Health Fri, 27 Feb 2009 06:26:14 EST news154938328 By studying how mice fight off infection by intestinal worms - a condition that affects more than 1 billion people worldwide - scientists have discovered that the immune system is more versatile than has long been thought. The work with worms is opening a new avenue of exploration in the search for treatments against autoimmune diseases like diabetes and asthma, where the body mistakenly attacks its own tissues. http://www.physorg.com/news154879979.html Medicine & Health Thu, 26 Feb 2009 14:13:30 EST news154879979 New research expands our understanding of how a type of immune cell called a B lymphocyte enables the immune system to mount a successful defense against an intestinal parasite. The study, published by Cell Press online in the journal Immunity on 26 February, provides some intriguing insight into the variety of mechanisms implemented by B cells to protect the host from infection. http://www.physorg.com/news154876355.html Medicine & Health Thu, 26 Feb 2009 13:13:13 EST news154876355 A layer of "dark cells" in the retina that is responsible for maintaining the health of the light-sensing cells in our eyes has been imaged in a living retina for the first time. http://www.physorg.com/news154869888.html Medicine & Health Thu, 26 Feb 2009 11:26:58 EST news154869888 Researchers have found a way to block the ability of white blood cells to sprint toward the sites of infection when such speed worsens the damage done by sepsis, the often fatal, whole-body bacterial infection, according to a study published today in the journal Blood. The results recommend existing drugs as potential new treatments against sepsis, and suggest improvements in the current treatment that would increase its effect while eliminating a treatment-related risk for internal bleeding. http://www.physorg.com/news154712115.html Medicine & Health Tue, 24 Feb 2009 15:37:00 EST news154712115 Children with high blood pressure are not as good at complicated, goal-directed tasks, have more working memory problems and are not as adept at planning as their peers without hypertension, according to recent research. If they are both hypertensive and obese, they are also more likely to have anxiety and depression. http://www.physorg.com/news154696066.html Medicine & Health Tue, 24 Feb 2009 11:08:15 EST news154696066 Measuring kidney function in children can be expensive, time-consuming for clinicians, and tedious for children, who may be exposed to radioactivity and subjected to a large number of blood draws. A new calculation eliminates many of these obstacles, relying instead on various blood tests that can be performed in a clinical setting to offer an accurate estimate of a child's kidney function. http://www.physorg.com/news154694617.html Medicine & Health Tue, 24 Feb 2009 10:44:15 EST news154694617 Some of the most breathtaking objects in the cosmos are the jets of matter streaming out of stars, but astrophysicists have long been at a loss to explain how these jets achieve their varied shapes. Now, laboratory research detailed in the current issue of Astrophysical Review Letters shows how magnetic forces shape these stellar jets. http://www.physorg.com/news153415816.html Space & Earth Mon, 09 Feb 2009 15:30:42 EST news153415816 A gene that helped one species split into two species shows evidence of adapting much faster than other genes in the genome, raising questions about what is driving its rapid evolution. http://www.physorg.com/news153066101.html Biology Thu, 05 Feb 2009 14:22:11 EST news153066101 Urban children with asthma engage in an average of an hour more of screen time daily than the maximum amount American Academy of Pediatrics (AAP) recommends. This is the first study to examine screen time among children with asthma. http://www.physorg.com/news152975897.html Medicine & Health Wed, 04 Feb 2009 13:18:45 EST news152975897 (PhysOrg.com) -- Quantum entanglement, a type of correlation peculiar to quantum objects, has been found to disregard completely the "half-life" rule that is obeyed by all natural processes, such a radioactive decay. http://www.physorg.com/news152899335.html Physics Tue, 03 Feb 2009 16:02:40 EST news152899335 In Arctic Canada, a team of geologists from the University of Rochester has discovered a surprise fossil: a tropical, freshwater, Asian turtle. The find strongly suggests that animals migrated from Asia to North America not around Alaska, as once thought, but directly across a freshwater sea floating atop the warm, salty Arctic Ocean. http://www.physorg.com/news152720213.html Other Sciences Sun, 01 Feb 2009 14:17:17 EST news152720213 Measuring a child's kidney function has traditionally been time-consuming, costly, and difficult to perform, but a new equation that uses parameters collected at routine office visits can effectively accomplish this, according to a study appearing in the March 2009 issue of the Journal of the American Society Nephrology (JASN). The formula could prove useful for measuring kidney function when young patients are given antibiotics, chemotherapy, and other drugs that could potentially injure the kidneys. The equation could also be valuable for monitoring kidney function in children with kidney disease. http://www.physorg.com/news151781179.html Medicine & Health Wed, 21 Jan 2009 17:27:11 EST news151781179 The next time a loved one brandishes a virtual shotgun in their favorite video game, take heart. That look of glee, says a new study, likely stems from the healthy pleasure of mastering a challenge rather than from a disturbing craving for carnage. http://www.physorg.com/news151307342.html Medicine & Health Fri, 16 Jan 2009 05:49:02 EST news151307342 A study released this month confirms and quantifies what many medical school deans and financial administrators have long understood: Basic science research can be an expensive luxury. The study, which was conducted by the University of Rochester School of Medicine and Dentistry, found that the school had to add 40 cents to every dollar of external grant support received by newly recruited scientists in order to achieve financial equilibrium. This is in contrast to support required for established scientists, which is considerably less. http://www.physorg.com/news150993162.html Medicine & Health Mon, 12 Jan 2009 14:32:42 EST news150993162 Bladder cancer is much more likely to be deadly for women and African-Americans, but the reasons long believed to explain the phenomenon account for only part of the differences for such patients compared to their white and male counterparts, according to results published in the Jan. 1 issue of the journal Cancer. http://www.physorg.com/news150646734.html Medicine & Health Thu, 08 Jan 2009 14:18:54 EST news150646734 Researchers at the University of Rochester have shown that the human brain -once thought to be a seriously flawed decision maker -is actually hard-wired to allow us to make the best decisions possible with the information we are given. The findings are published in today's issue of the journal Neuron. http://www.physorg.com/news149345120.html Medicine & Health Wed, 24 Dec 2008 12:45:20 EST news149345120
