Sheep Shed Light On Personality Differences Posted: 26 Sep 2009 02:00 PM PDT Scientists recently completed a study showing the link between personality, survival and reproductive success in male bighorn sheep. In addition to being a significant advance in our knowledge of these mammals, the research offers insight into personality differences in animals and humans, from an evolutionary perspective. |
Diabetes Drug Shows Promise In Fighting Lethal Cancer Complication Posted: 26 Sep 2009 02:00 PM PDT Insulin resistance, the hallmark of type 2 diabetes and a condition often associated with obesity, is paradoxically also an apparent contributor to muscle wasting and severe fat loss that accompanies some cancers, according to new research. |
Spot Discovered On Dwarf Planet Haumea Shows Up Red And Rich With Organics Posted: 26 Sep 2009 02:00 PM PDT A dark red area discovered on the dwarf planet Haumea appears to be richer in minerals and organic compounds than the surrounding icy surface. |
Coronary Imaging Techniques Helps To Identify Plaques Likely To Cause Heart Attacks Posted: 26 Sep 2009 02:00 PM PDT Late-breaking results from the PROSPECT clinical trial shed new light on the types of vulnerable plaque that are most likely to cause sudden, unexpected adverse cardiac events, and on the ability to identify them through imaging techniques before they occur. |
Scientists Discover How To Send Insects Off The Scent Of Crops Posted: 26 Sep 2009 02:00 PM PDT Scientists have discovered molecules that could confuse insects' ability to detect plants by interfering with their sense of smell. This could reduce damage to crops by insect pests and contribute to food security. |
Use Of Statins Favors The Wealthy, Creating New Social Disparities In Cholesterol, Study Finds Posted: 26 Sep 2009 02:00 PM PDT Since the introduction of statins to treat high cholesterol, the decline in lipid levels experienced by the wealthy has been double that experienced by the poor. Statin use may have contributed to expanding social disparities in the treatment of cardiovascular disease, according to new research. |
Engineers Track Bacteria's Kayak Paddle-like Motion For First Time Posted: 26 Sep 2009 08:00 AM PDT Engineers have for the first time observed and tracked E. coli bacteria moving in a liquid medium with a motion similar to that of a kayak paddle. The findings will help lead to a better understanding of how bacteria move from place to place and, potentially, how to keep them from spreading. |
Toad Venom In Cancer Treatment: Traditional Chinese Medicine Is Well-tolerated, Study Shows Posted: 26 Sep 2009 08:00 AM PDT Huachansu, a Chinese medicine that comes from the dried venom secreted by the skin glands of toads, has tolerable toxicity levels, even at doses eight times those normally administered, and may slow disease progression in some cancer patients, say US researchers. |
Detailed Glimpse Of Chemoreceptor Architecture In Bacterial Cells Posted: 26 Sep 2009 08:00 AM PDT Using state-of-the-art electron microscopy techniques, researchers have for the first time visualized and described the precise arrangement of chemoreceptors -- the receptors that sense and respond to chemical stimuli -- in bacteria. In addition, they have found that this specific architecture is the same throughout a wide variety of bacterial species, which means that this is a stable, universal structure that has been conserved over evolutionary time. |
Ultrasound Can Predict Tumor Burden And Survival In Melanoma Patients Posted: 26 Sep 2009 08:00 AM PDT Researchers have shown for the first time that patterns of ultrasound signals can be used to identify whether or not cancer has started to spread in melanoma patients, and to what extent. The discovery enables doctors to decide on how much surgery, if any, is required and to predict the patient's probable survival. |
Fish Fend Off Invading Germs With An Initial Response Similar To One Found In Humans Posted: 26 Sep 2009 08:00 AM PDT A new study demonstrates that the same proteins produced by humans early during infection are also made by fish early after exposure to harmful germs. These proteins activate the fish immune system in a process that resembles that in humans. But unlike humans, the inflammatory response in young zebrafish is simple, making it easier to tease out the pathways involved in the fight against infection. |
Many Medical Schools Report Incidents Of Students Posting Unprofessional Content Online Posted: 26 Sep 2009 08:00 AM PDT A majority of medical schools surveyed report they have experienced incidents of students posting unprofessional content online, including incidents involving violation of patient confidentiality, with few schools having policies to address these types of postings, according to a new study. |
'Green' Roofs Could Help Put Lid On Global Warming Posted: 26 Sep 2009 02:00 AM PDT "Green" roofs, those increasingly popular urban rooftops covered with plants, could help fight global warming, scientists in Michigan are reporting. Their study is the first of its kind to examine the ability of green roofs to sequester carbon which may impact climate change. |
Enzyme Is Key To Clogged Arteries, Scientists Find Posted: 26 Sep 2009 02:00 AM PDT Scientists have made an important discovery in understanding what causes arteries to clog up. They have discovered that an enzyme called matrix metalloproteinase-8 plays a crucial role in raising blood pressure and causing abnormal build-up of cells in the arteries -- both of which increase the risk of heart disease. The scientists say that their research could lead to new drugs for treating high blood pressure and preventing heart disease. |
Plants' Response To Fire Tested Posted: 26 Sep 2009 02:00 AM PDT Researchers in Spain have developed a new method for identifying the flammability of plant species by using a device that measures how construction materials react to fire. The technique can be used to improve fire risk maps. |
Obesity Hinders Chemotherapy Treatment In Children With Leukemia Posted: 26 Sep 2009 02:00 AM PDT Obesity is an important factor contributing to chemotherapy resistance and increasing relapse rates among children with leukemia, according to recent findings. |
New Computing Tool Could Lead To Better Crops And Pesticides Posted: 26 Sep 2009 02:00 AM PDT A new computing tool that could help scientists predict how plants will react to different environmental conditions in order to create better crops, such as tastier and longer lasting tomatoes, is being developed by researchers. |
Social Background Weighs Heavily On Teenage Diet Posted: 26 Sep 2009 02:00 AM PDT Teenagers' attitudes to diet and weight are shaped by their social class, according to new research. Policymakers have long insisted on the importance of understanding young people's health and eating habits but this is the first study to show how everyday practices and perceptions of different social classes contribute to variation in the diet, weight and health of teenagers. |
Peruvian Glacial Retreats Linked To European Events Of Little Ice Age Posted: 25 Sep 2009 05:00 PM PDT A new study that reports precise ages for glacial moraines in southern Peru links climate swings in the tropics to those of Europe and North America during the Little Ice Age approximately 150 to 350 years ago. The study brings scientists one step closer to understanding global-scale patterns of glacier activity and climate during the Little Ice Age. |
Increased Risk Of Birth Defects After PCE Exposure Posted: 25 Sep 2009 05:00 PM PDT Exposure to tetrachloroethylene (also known as perchlorethylene, PCE) may cause congenital birth defects. A study of expectant women exposed to PCE in drinking water found an increased risk of oral clefts and neural tube defects in their children. |
Prototype Developed To Detect Dark Matter Posted: 25 Sep 2009 05:00 PM PDT A team of researchers from Spain has developed a "scintillating bolometer" -- a device that the scientists will use in efforts to detect the dark matter of the universe. |
