AAAS decries latest stem cell veto

...in vitro fertility treatments. Current U.S. policy limits such funding to fewer than 20 stem cell lines that had been created when the president first announced U.S. policy in 2001. "Our concern is that this action has the potential to delay development of important new therapies by cutting off a promisi...

Machine preservation may promote more organ sharing

...enter’s success transplanting kidneys at the outer limits of the ECD acceptance criteria, such as organs donated after cardiac death, preserved for more than 30 hours, or from donors over age 70. In previous studies with up to four years of follow-up data, Stratta has shown that success rates with these org...

Legal ruling may put endangered species in danger

...es that could be hurt by the new definition, which limits endangered species to those simply "at risk of extinction." The scientists and philosophers protesting the ruling say that the original law defined an endangered species as one "at risk of extinction throughout all or a significant portion of its ran...

Dealing deadly cancers a knockout punch

...to treat cancer with multiple agents, but toxicity limits these approaches. Since reovirus typically is not pathogenic in humans nor associated with severe toxicity in clinical studies, its co-administration is not expected to increase a treatment's overall toxicity. Dual Mechanism Reovirus works by ...

A new portable biosensor detects traces of contaminants in food more quickly and cheaply

...ople. The European Community has established upper limits for the presence of traces of pesticides and antibiotics in food, but the control of these limits is carried out in laboratories with expensive, slow and bulky equipment. The sensor developed by...

Executable biology -- Computer science sheds light on animal development

...rly static picture of cellular processes, and this limits understanding of the details involved. Biologists and computer scientists from the EPFL (Ecole Polytechnique Federale de Lausanne) and the University of Zurich have taken a new approach, using formal methods of computer science to translate this pict...

Gut research yields new anti-cancer approach

... High-dose PPARgamma inhibitors may overcome the limits of current treatment because the profile of molecules likely to be pumped out by drug efflux proteins is known, and at least one of the PPARgamma inhibitors does not match it. In addition, PPARgamma inhibitors do not bind to the standard tubulin-bind...

Action video games sharpen vision 20 percent

.... "These games push the human visual system to the limits and the brain adapts to it. That learning carries over into other activities and possibly everyday life." The improvement was seen both in the part of the visual field where video game players typically play, but also beyond—the part of your vision...

Carnegie Mellon University research shows how sensory-deprived brain compensates

...s plasticity, or adapt, in response to injury that limits bodily motion. This latest study is the first to show such an impressive enhancement of brain activity in an animal with sensory loss. Losing sight, hearing, taste, smell or touch are common disabling side effects of traumatic brain injury and stroke...

Researchers first to map gene that regulates adult stem cell growth

...ents face is stem cell loss after treatments. This limits the dosage amount and types of chemotherapy that can be given. But if Latexin were used to increase the stem cell count, patients would be able to receive increased doses of chemotherapy and be able to recover more quickly. Increased stem cell counts...

T-ray breakthrough could make detecting disease far easier

...of lenses and mirrors to focus the radiation. This limits the spot size of focused T-rays to a substantial fraction of a millimetre and this has made studies of small objects such as biological cells with high resolution are virtually impossible. But in their work the researchers found that although ord...

Nanoscale microscope sheds first light on gene repair

...s behave, however, biophysicists are expanding the limits of light microscopy, and one of the latest advances--the 4Pi microscope--provides never-before-seen views of cellular components, including structures within the nucleus. In a paper published in the Proceedings of the National Academy of Sciences...

Artificial cornea offers better results for infants, some blind patients

...they're ever going to see. While astigmatism often limits the quality of vision with traditional corneal transplant, this new device produces no astigmatism and a clearer image." Aquavella evaluated the recent progress in an unusual study, with himself serving as the common point as he compared the outco...

Giant insects might reign if only there was more oxygen in the air

Flu shot effective against drifted influenza, nasal spray vaccine less so

... systems," Ohmit said. The FDA approval of FluMist limits its use to people between age 5 and 49 years. In another paper in the same edition of the New England Journal of Medicine, FluMist was administered to school children and the children were followed to see if they and their families had been protect...

Paramecia adapt their swimming to changing gravitational force

... even higher, Valles and Guevorkian could test the limits of protozoan endurance. At about eight times normal gravity, the little swimmers stalled, swimming upward, but making no progress. At this break-even point, the physicists could measure the force needed to counter the gravitational effect: 0.7 nano-N...

Bacteria that use radiated water as food

...urprisingly little about the origin, evolution and limits for life on Earth," said IUB biogeochemist Lisa Pratt, who led IU Bloomington's contribution to the project. "Scientists are just beginning to study the diverse organisms living in the deepest parts of the ocean. The rocky crust on Earth is virtually...

Commercial fishing causes dangerous fluctuations in fish populations

...naged by governments setting total allowable catch limits (TACs), but a fixed TAC which doesn't take into account the variability of abundance over time, may mean that in some years it is completely incompatible with the population size. This means that fishing vessels could unwittingly overexploit the popu...
