Scientists at the Stanford University School of Medicine have found a way to light up cells as they die. Physicians will potentially be able watch tumor cells committing a form of programmed suicide called apoptosis. The ability to observe the tumor cell behavior could prove helpful in more quickly picking the most effective treatment.
INDIANAPOLIS -- A new study by researchers from the Automotive Safety Program at Riley Hospital for Children and Indiana University School of Medicine published online July 13, 2009 in the journal Pediatrics reports that the parents of children with special health care needs are doing a good job with the selection of the appropriate child car seat but still need help in using it correctly.
Waste material from discarded televisions could be recycled and used in medicine, according to new research by scientists at the University of York.
The chemical compound polyvinyl-alcohol (PVA) is widely used in industry and is a key element of television sets with liquid crystal display (LCD) technology. When these sets are thrown away, the LCD panels are usually incinerated or buried in landfill sites.
Superconductivity appears to rely on very different mechanisms in two varieties of iron-based superconductors. The insight comes from research groups that are making bold statements about the correct description of superconductivity in iron-based compounds in two papers about to be published in journals of the American Physical Society.
KEYSTONE, CO (Saturday, July 11, 2009) – Knee injuries are a common problem in collegiate and professional football, often hindering an individual's career length and future. A study presented at the American Orthopaedic Society for Sports Medicine's Annual Meeting in Keystone, Colorado suggests that anterior cruciate ligament (ACL) reconstruction versus a simple meniscus repair may predict a longer professional career in those that have suffered knee injuries.
They've been dubbed "grassoline" – second generation biofuels made from inedible plant material, including fast-growing weeds, agricultural waste, sawdust, etc. – and numerous scientific studies have shown them to be prime candidates for replacing gasoline to meet our transportation needs. However, before we can begin to roll down the highways on sustainable, carbon-neutral grassoline, numerous barriers must be overcome, starting with finding ways to break lignocellulosic biomass down into fermentable sugars.
A team of researchers from the University of Huelva has developed an environmentally-friendly lubricating grease based on ricin oil and cellulose derivatives, according to the journal Green Chemistry. The new formula does not include any of the contaminating components used to manufacture traditional industrial lubricants.
Dental disease may be a wake-up call that your diet is harming your body.
"The five-alarm fire bell of a tooth ache is difficult to ignore," says Dr. Philippe P. Hujoel, professor of dental public health sciences at the University of Washington (UW) School of Dentistry in Seattle. Beyond the immediate distress, dental pain may portend future medical problems. It may be a warning that the high-glycemic diet that led to dental problems in the short term may, in the long term, lead to potentially serious chronic diseases.
BERKELEY, CA – Researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have demonstrated a way to fabricate efficient solar cells from low-cost and flexible materials. The new design grows optically active semiconductors in arrays of nanoscale pillars, each a single crystal, with dimensions measured in billionths of a meter.
