It could be they're hungry -- for each other Since ancient times, locust plagues have been viewed as one of the most spectacular events in nature. In seemingly spontaneous fashion, as many as 10 billion critters can suddenly swarm the air and carpet the ground, blazing destructive paths that bring starvation and economic ruin. Dying bats in the Northeast remain a mystery Investigations continue into the cause of a mysterious illness that has resulted in the deaths of thousands of bats since March 2008. At more than 25 caves and mines in the northeastern U.S, bats exhibiting a condition now referred to as "white-nosed syndrome" have been dying. Young people are intentionally taking drink and drugs for better sex Teenagers and young adults across Europe drink and take drugs as part of deliberate sexual strategies. Findings published today in BioMed Central's open access journal, BMC Public Health, reveal that a third of 16-35 year old males and a quarter of females surveyed are drinking alcohol to increase their chances of sex, while cocaine, ecstasy and cannabis are intentionally used to enhance sexual arousal or prolong sex. Model successfully predicts large river system fish diversity While scientists have developed methods to predict aspects of fish diversity in specific river locations, a model to understand what factors may drive a comprehensive suite of fish biodiversity patterns in a large and complex system of rivers has been elusive. Scientists demonstrate method for integrating nanowire devices directly onto silicon Applied scientists at Harvard University in collaboration with researchers from the German universities of Jena, Gottingen, and Bremen, have developed a new technique for fabricating nanowire photonic and electronic integrated circuits that may one day be suitable for high-volume commercial production. Scientists Identify Key Roadblock to Gene Expression A team of scientists has provided, for the first time, a detailed map of how the building blocks of chromosomes, the cellular structures that contain genes, are organized in the fruit fly Drosophila melanogaster. Hopkins researchers discover new link to schizophrenia Neuroscientists at Johns Hopkins have discovered that mice lacking an enzyme that contributes to Alzheimer disease exhibit a number of schizophrenia-like behaviors. Berkeley Researchers Identify Photosynthetic Dimmer Switch In a study of the molecular mechanisms by which plants protect themselves from oxidation damage should they absorb too much sunlight during photosynthesis, a team of researchers has discovered a molecular "dimmer switch" that helps control the flow of solar energy moving through the system of light harvesting proteins. TU Delft demonstrates for the first time how light squeezes through small holes How does light pass through a tiny hole" For the first time, Dr Aurele Adam and Prof. Paul Planken of Delft University of Technology, in conjunction with two South Korean and one German research groups, have succeeded in mapping this process properly. Racial discrimination has different mental health effects on Asians, study shows The first national study of Asians living in the United States shows that for some individuals, strong ties to their ethnicity can guard against the negative effects of racism. Study finds link between birth order and asthma symptoms Among four year-olds attending Head Start programs in New York City, those who had older siblings were more likely to experience respiratory symptoms including an episode of wheezing in the past year than those who were oldest or only children. New technique measures ultrashort laser pulses at focus Lasers that emit ultrashort pulses of light are used for numerous applications including micromachining, microscopy, laser eye surgery, spectroscopy and controlling chemical reactions. But the quality of the results is limited by distortions caused by lenses and other optical components that are part of the experimental instrumentation. University of Leicester to lead audit of adults with autism The University of Leicester is leading on a national study to calculate the number of adults with autism, it has been announced today. Phase III pivotal results presented of VYVANSE to treat ADHD in adults Shire plc (LSE: SHP, Nasdaq: SHPGY), the global specialty biopharmaceutical company, today presented the results of a phase III pivotal study in which VYVANSE demonstrated significant improvements in Attention Deficit Hyperactivity Disorder (ADHD) symptoms in adults and met all safety and efficacy endpoints. When statins aren't enough: New trial drug points to better management of coronary heart disease Despite widespread use of cholesterol-lowering drugs, a significant number of cardiac patients continue to suffer heart attacks and stroke. Researchers theorize that high levels of an enzyme found in coronary plaques may be to blame, by making plaques more likely to rupture and block blood flow. Previously unseen switch regulates breast cancer response to estrogen A tiny modification called methylation on estrogen receptors prolongs the life of these growth-driving molecules in breast cancer cells, according to research by scientists at Emory University's Winship Cancer Institute. New study shows how genes control blood proteins important to health A new study shows how genes control levels of many blood proteins implicated in disease. The findings are the result of an international collaboration between scientists at the University of Exeter, the National Institute on Aging, and the Tuscany and Florence Health Agencies. Magnet Lab researchers make observing cell functions easier Now that the genome (DNA) of humans and many other organisms have been sequenced, biologists are turning their attention to discovering how the many thousands of structural and control genes -- the "worker bees" of living cells that can turn genes on and off -- function. Improving anxiety treatment through the help of brain imaging: A potential future treatment strategy Wouldn't it be nice if our doctors could predict accurately whether we would respond to a particular medication" This question is important because research studies provide information about how groups of patients tend to respond to treatments, but inevitably, differences among groups of patients with the same diagnosis mean that findings about groups of patients may not apply to individuals from those groups. Skin flaps deliver cancer-fighting therapy, ASPS study reveals Using gene therapy, plastic surgeons have delivered cancer fighting proteins through skin flaps placed on cancerous tumors on rats with a 79 percent reduction in tumor volume. New cost-effective means to reconstruct virus populations Researchers from the United States and Switzerland have developed mathematical and statistical tools for reconstructing viral populations using pyrosequencing, a novel and effective technique for sequencing DNA. They describe their findings in an article published May 9th in the open-access journal PLoS Computational Biology. Risks for painkiller abuse do not outweigh benefits in chronic pain As controversy swirls about proper clinical use of opioids and other potent pain medications, research reported at the American Pain Society annual meeting shows that, contrary to widespread beliefs, less than 3 percent of patients with no history of drug abuse who are prescribed opioids for chronic pain will show signs of possible drug abuse or dependence. 6-month follow-up diagnostic mammograms recommended for women with probably benign lesions Radiologists can, with confidence, recommend a six-month follow-up diagnostic mammogram rather than an immediate biopsy for patients with "probably benign" breast lesions, a new study emphasizes. |
