The "Lance Armstrong effect" could become a powerful new weapon to fight cancer cells that develop resistance to chemotherapy, radiation and other treatments, scientists say in a report in the ACS journal Molecular Pharmaceutics.

It is well known that hard training can lead to degradation of muscle protein. A number of nutritional strategies have been developed to counter this but surprisingly there has to date been very little attention paid to the situation in sport horses. Preliminary data showing that nutritional supplements given after exercise may also help prevent muscle breakdown in horses are now provided by René van den Hoven and colleagues in the Institute of Animal Nutrition at the University of Veterinary Medicine, Vienna.
Ecologists are a step closer to understanding one of nature's most extraordinary sights – the 'arribada' or synchronised mass nesting of female olive ridley sea turtles. The new study, published today in the British Ecological Society's Journal of Animal Ecology, is the first to combine three different approaches – genetics, demography and behaviour, and the results should help conserve these vulnerable marine creatures.
Women with high blood pressure (hypertension) in the early stages of pregnancy are more likely to have babies with birth defects, irrespective of commonly prescribed medicines for their condition, finds new research published on bmj.com today.
The finding suggests that it is the underlying hypertension, rather than the use of antihypertensive drugs in early pregnancy, that increases the risk of birth defects.
Why did the approval ratings of President George W. Bush— who was perceived as indecisive before September 11, 2001—soar over 90 percent after the terrorist attacks? Because Americans were acutely aware of their own deaths.
Seattle, 18 October 2011 — First results from a large-scale Phase III trial of RTS,S, published online today in the New England Journal of Medicine (NEJM), show the malaria vaccine candidate to provide young African children with significant protection against clinical and severe malaria with an acceptable safety and tolerability profile. The results were announced today at the Malaria Forum hosted by the Bill & Melinda Gates Foundation in Seattle, Washington.

Smithsonian scientists have discovered two new, closely related bee species: one from Coiba Island in Panama and another from northern Colombia. Both descended from of a group of stingless bees that originated in the Amazon and moved into Central America, the ancestors of Mayan honeybees. The presence of one of these new species on Coiba and Rancheria Islands, and its absence from the nearby mainland, is a mystery that will ultimately shed light on Panama's history and abundant biodiversity.
CHAPEL HILL, N.C. — First results from a large-scale Phase III trial of RTS,S*, published online today in the New England Journal of Medicine (NEJM), show the malaria vaccine candidate to provide young African children with significant protection against clinical and severe malaria with an acceptable safety and tolerability profile. The results were announced today at the Malaria Forum hosted by the Bill & Melinda Gates Foundation in Seattle, Washington.
Genetic resistance to a parasitic nematode that infects sheep has been discovered by a team of scientists with the U.S. Department of Agriculture (USDA) and the International Livestock Research Institute (ILRI).
For better and for worse, human health depends on a cell's motility –– the ability to crawl from place to place. In every human body, millions of cells –are crawling around doing mostly good deeds ––– though if any of those crawlers are cancerous, watch out.
Scientists have successfully demonstrated that they can build some of the basic components for digital devices out of bacteria and DNA, which could pave the way for a new generation of biological computing devices, in research published today in the journal Nature Communications.
It's time for forgetting to get some respect, says Ben Storm, author of a new article on memory in Current Directions in Psychological Science, a journal of the Association for Psychological Science. "We need to rethink how we're talking about forgetting and realize that under some conditions it actually does play an important role in the function of memory," says Storm, who is a professor at the University of Illinois at Chicago.
Chronic obstructive pulmonary disease (COPD) leads to persistent inflammation of the airways and is typically managed with corticosteroids, a class of anti-inflammatory medication. However, corticosteroids do not improve survival nor alter the progression of COPD and may reduce lung symptoms as little as 20 percent.
Vampires on the "True Blood" television series are already enjoying the advantages of synthetic blood. While this may seem to be only the imagination on the big screen, the true benefits of blood manufactured from embryonic stem cells may be less than a decade away.
