Protein that promotes cancer cell growth identified
— 01:43 GMT | HealthScientists at Burnham Institute for Medical Research (Burnham) have found that the Caspase-8 protein, long known to play a major role in promoting programmed cell death (apoptosis), helps relay signals that can cause cancer cells to proliferate, migrate and invade surrounding tissues. The study was published in the journal Cancer Research on 15 June…
Alternative agricultural practices combine productivity and soil health
— 01:38 GMT | EnvironmentThe progressive degradation of useful soils for agriculture and farm animal husbandry is a growing environmental and social problem, given that it endangers the food safety of an increasing world population. This fact prompted the Basque Institute for Agricultural Research and Development - Neiker-Tecnalia - to design a series of research projects in order to evaluate alternative agricultural practices, as a function of their capacity to combine the productivity of crops with the health of the soil…
Airway cells use 'tasting' mechanism to detect and clear harmful substances
— 01:33 GMT | HealthThe same mechanism that helps you detect bad-tasting and potentially poisonous foods may also play a role in protecting your airway from harmful substances, according to a study by scientists at the University of Iowa Roy J. and Lucille A. Carver College of Medicine. The findings could help explain why injured lungs are susceptible to further damage…
New drug may reduce heart attack damage
— 01:28 GMT | HealthA novel drug that targets a master disease-causing gene can dramatically reduce heart muscle damage after a heart attack and may lead to significantly improved patient outcomes, researchers at the University of New South Wales (UNSW) have shown…

Is RTA a new potential option for the treatment of hydatid cysts?
— 01:19 GMT | HealthCurrent treatment of cystic echinococcosis is surgery or percutaneous aspiration, injection and reaspiration (PAIR) using hypertonic saline or ethanol. It is aimed at causing permanent damage to the endocyst - the thin, delicate, and translucid inner membrane that produces the cystic fluid and generates new larval elements able to expand the infestation. Surgery and PAIR on liver and lung can result in biliary or bronchial fistulae, prompted by endocyst detachment; chemical cholangitis or pneumonia, due to passing of hypertonic saline or ethanol into the biliary or bronchial tree; and infection or abscess on the residual cyst cavity…
Ants more rational than humans
— 00:44 GMT | BiologyIn a study released online on 22 July in the journal Proceedings of the Royal Society: Biological Sciences, researchers at Arizona State University and Princeton University show that ants can accomplish a task more rationally than our - multimodal, egg-headed, tool-using, bipedal, opposing-thumbed - selves…
Improved air quality during Beijing Olympics could inform pollution-curbing policies
— 00:39 GMT | EnvironmentThe air in Beijing during the 2008 Olympics was cleaner than the previous year's, due to aggressive efforts by the Chinese government to curtail traffic, increase emissions standards and halt construction in preparation for the games, according to a Cornell study…
One in six public health workers unlikely to respond in pandemic flu emergency
— 00:34 GMT | HealthApproximately one in six public health workers said they would not report to work during a pandemic flu emergency regardless of its severity, according to a survey led by researchers at the Johns Hopkins Bloomberg School of Public Health. The findings are a significant improvement over a 2005 study conducted by the same research team, in which more than 40 percent of public health employees said they were unlikely to report to work during a pandemic emergency. The new study suggests ways for improving the response of the public health workforce. The results are published in the July 24 edition of the journal PLoS ONE…
Knee injuries may start with strain on the brain, not the muscles
