Nematodes, microscopic worms, are making engineers look twice at their ability to exhibit the "Cheerios effect" when they move in a collective motion.
These parasites will actually stick together like Cheerios swimming in milk in a cereal bowl after a chance encounter "due to capillary force." This observation has made Virginia Tech engineers speculate about the possible impacts on the study of biolocomotion.
Heikenfeld is part of an internationally prestigious UC team that specializes in research and development of e-devices.
Coming later this year:
University of Granada scientists and the Spanish Higher Institute for Scientific Research (CSIC) have made significant progress in understanding lipid membranes, which are extensively employed in the development of cosmetic and drug products, and which have potential application in the field of nanotechnology.
Rhizanthella gardneri is a cute, quirky and critically endangered orchid that lives all its life underground. It even blooms underground, making it virtually unique amongst plants.
Last year, using radioactive tracers, scientists at The University of Western Australia showed that the orchid gets all its nutrients by parasitising fungi associated with the roots of broom bush, a woody shrub of the WA outback.
Now, with less than 50 individuals left in the wild, scientists have made a timely and remarkable discovery about its genome.
Park Ridge, IL (February 8, 2011) – According to new nutrition data from the United States Department of Agriculture's Agricultural Research Service (USDA-ARS), eggs are lower in cholesterol than previously thought. The USDA-ARS recently reviewed the nutrient composition of standard large eggs, and results show the average amount of cholesterol in one large egg is 185 mg, 14 percent lower than previously recorded. The analysis also revealed that large eggs now contain 41 IU of vitamin D, an increase of 64 percent.
Post-traumatic stress disorder can affect soldiers after combat or ordinary people who have undergone harrowing experiences. Of course, feelings of anxiety are normal and even desirable – they are part of what helps us survive in a world of real threats. But no less crucial is the return to normal – the slowing of the heartbeat and relaxation of tension – after the threat has passed. People who have a hard time "turning off" their stress response are candidates for post-traumatic stress syndrome, as well as anorexia, anxiety disorders and depression.
DETROIT ¬– A Henry Ford Hospital study has found that a pharmacist-directed anticoagulation service improves the way medication is managed for patients with heparin-induced thrombocytopenia (HIT), a common but life-threatening thromboembolic disorder.
Researchers found that patients treated by the anticoagulation service had a favorable response to alternative anticoagulant drugs three times faster and were 32 percent more likely to receive proper dosage than patients who were treated with the same drugs by the patient's primary medical team.
New research from Warwick Medical School published today in the European Heart Journal shows that prolonged sleep deprivation and disrupted sleep patterns can have long-term, serious health implications. Leading academics from the University have linked lack of sleep to strokes, heart attacks and cardiovascular disorders which often result in early death.
Toronto – Faster approval times for generic drugs will get them into consumers' hands quicker, but may not make the price any better, a pricing and marketing researcher has found.
A mathematical model created by Andrew Ching shows that fewer firms enter the marketplace because the chances of getting there first and commanding the best profits are dramatically smaller when drug approval times are shorter. Ching is an associate professor of marketing at the University of Toronto's Rotman School of Management.
CORVALLIS, Ore. – The air pollution control measures that were put in place in Beijing during the 2008 Olympic Games – if continued – would cut almost in half the lifetime risk of lung cancer for the area's residents from certain inhaled pollutants, a new study concludes.
This might translate to about 10,000 fewer lifetime cases of lung cancer in this large metropolitan area, scientists said, which is only one of several in China that have unhealthy levels of air pollution, largely from the burning of coal, biomass and automobile exhaust in a rapidly growing economy.
Up to three quarters of hospital tests are not being followed up, suggests a systematic review of international evidence, published in BMJ Quality and Safety.
This failure can have serious implications for patients, including missed or delayed diagnoses and even death, the study shows.
The authors base their findings on a systematic review of evidence published in English between 1990 and 2010, and available on reputable research databases.
STANFORD, Calif. — The root causes of complex diseases such as type-2 diabetes and obesity have been difficult to identify because the diseases are, well, complex. They occur at the dicey biological intersection of genes and environment, and, because they arose in our relatively recent past, it's not easy to simply compare DNA sequences from "then" and "now" to pinpoint likely genetic culprits.
Never before has a therapy proven more beneficial for women than men in preventing heart disease – until now.
A new study, published today in the Journal of the American College of Cardiology, found that women receive a significantly greater benefit – a 70 percent reduction in heart failure and a 72 percent reduction in death – from cardiac resynchronization therapy with defibrillator (CRT-D) than men.
Use of medical, mental health and case management services for young adults with an autism spectrum disorder appears to decline after high school, according to a report in the February issue of Archives of Pediatrics & Adolescent Medicine, one of the JAMA/Archives journals.
Berkeley – New experiments at the University of California, Berkeley, may one day lead to anti-viral treatments that involve swallowing Salmonella bacteria, effectively using one bug to stop another.
