(PhysOrg.com) -- A fruit fly's immune system can tell time -and how hard it punches back against infections depends on whether the fly is snoozing or cruising. The discovery by medical school researchers could have implications for human health, too. http://www.physorg.com/news150651380.html Biology Thu, 08 Jan 2009 15:36:20 EST news150651380 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 Scientists have identified mutations in a gene that predict a high likelihood of relapse in children with acute lymphoblastic leukemia (ALL). Although the researchers caution that further research is needed to determine how changes in the gene, called IKZF1 or IKAROS, lead to leukemia relapse, the findings are likely to provide the basis for future diagnostic tests to assess the risk of treatment failure. By using a molecular test to identify this genetic marker in ALL patients, physicians should be better able to assign patients to appropriate therapies. http://www.physorg.com/news150571442.html Medicine & Health Wed, 07 Jan 2009 17:24:02 EST news150571442 (PhysOrg.com) -- As people age, memory and the ability to carry out tasks often decline. Scientists looking for ways to lessen that decline often have focused on the "gray matter" -- the cortical regions where high-level functions such as memory are located. http://www.physorg.com/news150562618.html Medicine & Health Wed, 07 Jan 2009 14:56:58 EST news150562618 When babies develop a fever high enough or abrupt enough to cause a seizure, frightened parents often rush them to the emergency room, where their workup frequently includes a lumbar puncture (spinal tap) to rule out bacterial meningitis. Now, in the largest study to date, researchers at Children's Hospital Boston find that this uncomfortable procedure is probably not necessary in well-appearing children who have had a simple febrile seizure. Findings are published in the January issue of Pediatrics. http://www.physorg.com/news150483552.html Medicine & Health Tue, 06 Jan 2009 16:59:12 EST news150483552 (PhysOrg.com) -- Astronomers have turned to an unexpected place to study the evolution of planets -- dead stars. Observations made with NASA's Spitzer Space Telescope reveal six dead "white dwarf" stars littered with the remains of shredded asteroids. This might sound pretty bleak, but it turns out the chewed-up asteroids are teaching astronomers about the building materials of planets around other stars. http://www.physorg.com/news150394045.html Space & Earth Mon, 05 Jan 2009 16:07:25 EST news150394045 One part of the prenatal brain that may be particularly sensitive to alcohol's effects is white matter, nerve fibers through which information is exchanged between different areas of the central nervous system. A recent study has demonstrated that alcohol consumption during pregnancy can alter the microstructural integrity of developing fetal cerebral white matter in the frontal and occipital lobes of the brain. These anomalies may help to explain the executive dysfunction and visual processing deficits that are associated with gestational alcohol exposure. http://www.physorg.com/news148927034.html Medicine & Health Fri, 19 Dec 2008 16:37:14 EST news148927034 (PhysOrg.com) -- Duke University and United States Army scientists have found that a cheap and nontoxic sunburn and diaper rash preventative can be made to produce brilliant light best suited to the human eye. http://www.physorg.com/news148830246.html Nanotechnology Thu, 18 Dec 2008 13:44:06 EST news148830246 A new study of college freshman suggests that African Americans may obtain higher grades if they live with a white roommate. A detailed study of students at a large, predominantly-white university revealed that while living with a white roommate may be more challenging than living with someone of the same race, many Black students appear to benefit from the experience. http://www.physorg.com/news148578200.html Other Sciences Mon, 15 Dec 2008 15:43:20 EST news148578200 (PhysOrg.com) -- A team of German and American astronomers present far-ultraviolet observations of white dwarf KPD 0005+5106 and reveal that it is among the hottest stars ever known with a temperature of 200 000 K at its surface. Astronomy & Astrophysics is publishing this discovery, which was made through spectroscopic observations with NASA's space-based Far-Ultraviolet Spectroscopic Explorer (FUSE). http://www.physorg.com/news148315351.html Space & Earth Fri, 12 Dec 2008 14:42:31 EST news148315351 Is race defined by appearance, or can a person also be colored by socioeconomic status? A new study finds that Americans who are unemployed, incarcerated or impoverished today are more likely to be classified and identified as black, by themselves or by others, regardless of how they were seen -- or self identified -- in the past. http://www.physorg.com/news147980419.html Other Sciences Mon, 08 Dec 2008 17:40:19 EST news147980419 (PhysOrg.com) -- It is a truth universally acknowledged that quantum computing must have entanglement. http://www.physorg.com/news147698804.html Physics Fri, 05 Dec 2008 11:26:44 EST news147698804 (PhysOrg.com) -- Scientists peered at the brains of people with a baffling chronic pain condition and discovered something surprising. Their brains looked like an inept cable guy had changed the hookups, rewiring the areas related to emotion, pain perception and the temperature of their skin. http://www.physorg.com/news146922947.html Medicine & Health Wed, 26 Nov 2008 11:55:47 EST news146922947 For the first time, scientists have been able to map the disruption in neural circuitry of people suffering from congenital prosopagnosia, sometimes known as face blindness, and have been able to offer a biological explanation for this intriguing disorder. http://www.physorg.com/news146840077.html Medicine & Health Tue, 25 Nov 2008 12:54:37 EST news146840077 The initial evaluation and management of injured patients from minority ethnic groups nationwide appears to be similar to that of non-Hispanic white patients, according to a report in the November issue of Archives of Surgery, one of the JAMA/Archives journals. http://www.physorg.com/news146164099.html Medicine & Health Mon, 17 Nov 2008 17:08:19 EST news146164099 A research paper, by Dr Stuart Fraser of Warwick Business School at the University of Warwick, has found that many Ethnic Minority owned Businesses (EMBs) in the UK struggle to obtain credit in comparison to White owned businesses. Black and Bangladeshi owned businesses are the most likely to be refused credit, facing up to four times as many refusals as white owned businesses. http://www.physorg.com/news146145251.html Other Sciences Mon, 17 Nov 2008 11:54:11 EST news146145251 Young and healthy African-American men have higher central blood pressure and their blood vessels are stiffer compared to their white counterparts, signs that the African American men are developing hypertension early and with little outward sign, according to a new study. While the study found that central blood pressure -- the pressure in the aorta, near the heart -- was higher in the African-American men, the study found no difference in brachial blood pressure -- measured on the arm -- between the two groups. http://www.physorg.com/news146115498.html Medicine & Health Mon, 17 Nov 2008 03:38:18 EST news146115498 (PhysOrg.com) -- Scientists have discovered a way to potentially restore colour to white hair, new research in the British Journal of Dermatology reveals this month. http://www.physorg.com/news145811279.html Medicine & Health Thu, 13 Nov 2008 15:07:59 EST news145811279 A new American Cancer Society study finds that recent progress in closing the gap in overall cancer mortality between African Americans and whites may be due primarily to smoking-related cancers, and that cancer mortality differences related to screening and treatment may still be increasing. The study, appearing in the November issue of Cancer Epidemiology Biomarkers and Prevention, is the first to analyze racial and ethnic differences between the two broad categories of disease. http://www.physorg.com/news145182323.html Medicine & Health Thu, 06 Nov 2008 08:25:23 EST news145182323 Both first- and second-generation immigrants to the United Kingdom appear to have a higher risk of psychoses than white British individuals, according to a report in the November issue of Archives of General Psychiatry, one of the JAMA/Archives journals. http://www.physorg.com/news144950125.html Medicine & Health Mon, 03 Nov 2008 15:55:25 EST news144950125 (PhysOrg.com) -- The grid`s huge communication and computation capacities could let scientists gather data and run remote experiments anywhere in the world.
