Small hairy balls hide foul-tasting healthful enzymes (November 28, 2009) -- A Dutch researcher has discovered a new way to package enzymes by causing charged polymers to form a 'ball of hair' around them. Her approach significantly increases the utility of the enzymes. For example, healthy enzymes with a foul taste can be packaged in such a way that they are released in the stomach without being tasted. ... > full story
New treatment more than doubles survival for high risk childhood leukemia (November 28, 2009) -- Phase 2 study results show high-dose imatinib plus chemo more than doubled survival for high risk type of childhood leukemia. ... > full story
Volunteers wanted for simulated 520-day Mars mission (November 28, 2009) -- Starting in 2010, an international crew of six will simulate a 520-day round-trip to Mars, including a 30-day stay on the martian surface. In reality, they will live and work in a sealed facility in Moscow, Russia, to investigate the psychological and medical aspects of a long-duration space mission. ESA is looking for European volunteers to take part. ... > full story
Common herbicides and fibrates block nutrient-sensing receptor found in gut and pancreas (November 28, 2009) -- Certain common herbicides and lipid-lowering fibrate drugs act in humans to block T1R3, a nutrient-sensing taste receptor also present in intestine and pancreas. These compounds were not previously known to act on the receptor, which influences glucose homeostasis and energy metabolism. The effect is specific to humans and not revealed during animal testing. ... > full story
Control of mosquito vectors of malaria may be enhanced by a new method of biocontrol (November 28, 2009) -- Biopesticides containing a fungus that is pathogenic to mosquitoes may be an effective means of reducing malaria transmission, particularly if used in combination with insecticide-treated bednets, according to a modeling study. Results of the study show that incorporating this novel vector control technique into existing vector management programs may substantially reduce malaria transmission rates and help manage insecticide resistance. ... > full story
Obese patients' reaction to diet can be predicted, study finds (November 28, 2009) -- The presence of increased body fat, and therefore higher levels of inflammatory substances in the blood, hinders the loss and maintenance of body weight, as shown by new research from Spain. ... > full story
With first neutrino events, physicists closer to answering why only matter in universe (November 27, 2009) -- Physicists have just announced that they have detected the first neutrino events generated by the newly built neutrino beam at the J-PARC accelerator laboratory in Tokai, Japan. Neutrino oscillations, which require neutrinos to have mass and therefore were not allowed in previous theoretical understanding of particle physics, probe new physical laws and are of great interest in the study of the fundamental constituents of matter. ... > full story
Nano-scale drug delivery developed for chemotherapy (November 27, 2009) -- Bioengineers have developed a simple and inexpensive method for loading cancer drug payloads into nano-scale delivery vehicles and demonstrated in animal models that this new nanoformulation can eliminate tumors after a single treatment. ... > full story
Study pits man versus machine in piecing together 425-million-year-old jigsaw (November 27, 2009) -- Reconstructing ancient fossils from hundreds of thousands of jumbled up pieces can prove challenging. A new study tested the reliability of expert identification versus computer analysis in reconstructing fossils. The investigation, based on fossil teeth from extinct vertebrates, found that the most specialized experts provided the most reliable identifications. ... > full story
Drug therapy more cost-effective than angioplasty for diabetic patients with heart disease, study suggests (November 27, 2009) -- Many patients with diabetes should forego angioplasties for heart disease and just take medicine instead, a new study suggests. ... > full story
Plasma-in-a-bag for sterilizing devices (November 27, 2009) -- The practice of sterilizing medical tools and devices helped revolutionize health care in the 19th century because it dramatically reduced infections associated with surgery. Through the years, numerous ways of sterilization techniques have been developed, but the old mainstay remains a 130-year-old device called an autoclave, which is something like a pressure steamer. Now researchers in the Netherlands are developing a new way to sterilize medical devices by sealing them inside plastic bags and then using electromagnetic fields to create plasmas -- partially ionized gasses that contain free electrons and reactive ions. ... > full story
Comforted by carpet: How do floors and distance affect purchases? (November 27, 2009) -- Consumers who stand on carpeted flooring feel comforted, but they judge products close to them to be less comforting, according to a new study. ... > full story
