World aides series : advances in research in prevention of mother-to-child HIV-1 transmission
'Although substantial progress has been made in preventing mother-to-child HIV-1 transmission in the past decade, critical research questions remain. Two perinatal epidemics now exist. In more-developed countries, integration of prenatal HIV-1 counselling and testing programmes into an existing antenatal infrastructure, availability of effective... view more... (2000-06-22)
Screening for complex genetic interactions
In a report published online ahead of the January 15th print edition, Dr. David Amberg (SUNY Upstate Medical University) and colleagues have developed a large-scale reverse genetic screen to identify complex haploinsufficient interactions in S. cerevisiae. view more (2006-12-28)
A novel explanation for a floral genetic mystery
Scientists at the University of Jena, Germany have put forth a novel explanation of the evolutionary driving force behind a genetic switching circuit that regulates flower development and survival. view more (2009-01-16)
Genetic engineering of plants: nature was first
Queen Mary and Westfield College scientists studying resistance to infection in plants have discovered by chance that a natural form of genetic engineering has already brought foreign genes into their genetic make-up. view more (1998-09-01)
More findings on gene involved in childhood asthma
Asthma researchers have found that a gene variant known to raise the risk of childhood asthma in European children plays a similar role in white American children, but not in African American children. view more (2008-09-16)
DNA testing may unlock secrets of medieval manuscripts
Thousands of painstakingly handwritten books produced in medieval Europe still exist today, but scholars have long struggled with questions about when and where the majority of these works originated. view more (2009-01-12)
New method for HIV testing holds promise for developing world
A new technique that detects the HIV virus early and monitors its development without requiring refrigeration may make AIDS testing more accessible in sub-Saharan Africa. view more (2009-07-22)
Human Genetic Research: House Of Lords Debate
As the second main item of business on Tuesday 15 January (starting between about 5pm and 6pm), the House of Lords is to debate the Science and Technology Committee's recent report Human Genetic Databases: challenges and opportunities together with the Government's response. The debate will be opened by Lord Oxburgh (Ron Oxburgh, the former Rector... view more... (2002-01-09)
Mayo Clinic finding may double genetic screening effectiveness for sudden death heart condition
Currently that genetic test correctly detects HCM only 40 percent of the time. But coupled with imaging information, the detection power of the test nearly doubles, to 79 percent, says Steve Ommen, M.D., director of Mayo's HCM Clinic and co-lead investigator of the Mayo Clinic research team. view more (2006-04-20)
Pointing a finger at the source of fecal bacteria
Excessive levels of fecal bacteria were to blame for almost 60 percent of Nebraska streams deemed impaired by federal and state environmental laws in 2004. view more (2007-05-24)
Imaging study links key genetic risk for Alzheimer's disease to myelin breakdown
A new UCLA imaging study shows that age-related breakdown of myelin, the fatty insulation coating the brain's internal wiring, correlates strongly with the presence of a key genetic risk factor for Alzheimer disease. view more (2006-01-03)
Nanowire generates power by harvesting energy from the environment
As the sizes of sensor networks and mobile devices shrink toward the microscale, and even nanoscale, there is a growing need for suitable power sources. Because even the tiniest battery is too big to be used in nanoscale devices, scientists are exploring nanosize systems that can salvage energy from the environment. view more (2007-09-28)
Gene testing doesn't increase anxiety, depression in children of people with Alzheimer's
Adult children of people with Alzheimer's disease were satisfied and unharmed by the experience of genetic risk assessment, even when results suggested they might be at risk, according to new findings presented by Robert C. Green at the recent International Conference on the Prevention of Dementia, sponsored by the Alzheimer's Association. view more (2005-06-24)
Special issue on cystic fibrosis in The Journal of Pediatrics
Cystic fibrosis is a common, fatal genetic disease in which a gene causes the body to produce abnormally thick, sticky mucus. view more (2005-10-04)
Study: Genetic risk for substance use can be neutralized by good parenting
A genetic risk factor that increases the likelihood that youth will engage in substance use can be neutralized by high levels of involved and supportive parenting, according to a new University of Georgia study. view more (2009-02-11)
Trial Seeks 'Genetic Fingerprint' for Predicting Drug Effectiveness
University of Cincinnati (UC) physician-scientists believe identifying a genetic "fingerprint" could help predict which specific therapies will be most effective for patients with gastric cancer. view more (2007-10-04)
New research may overturn conventional wisdom on drug-resistant tuberculosis
A newly released study suggests that the majority of cases of drug-resistant tuberculosis (TB) among patients undergoing treatment for the disease may be due to new infections, not acquired resistance. view more (2007-02-21)
In a bug-eat-bug world, researchers are using a unique Chinese import to battle soybean aphids
University of Minnesota scientists are field testing a beneficial insect, a stingless wasp from China also known as Binodoxys communis, that kills soybean aphids. A successful field test would be a major breakthrough in controlling a damaging crop pest. view more (2007-07-25)
Safety checks for GM foods must be better, says Royal Society
Safety assessments should be improved before a greater variety of foods made from genetically modified plants are declared fit for human consumption, a Royal Society report warns today (4 February 2002). The report concludes that there is no reason to doubt the safety of foods made from GM ingredients that are currently available, nor to believe... view more... (2002-02-04)
Health benefits of Chlamydia screening programmes 'might have been overestimated'
The benefits and cost effectiveness of Chlamdyia screening programmes "might have been overestimated," suggest researchers in the journal Sexually Transmitted Infections. view more (2006-05-25)
