Orangutans count on stats for survival (November 20, 2010) -- Orangutans threatened with extinction could be brought back from the brink with help from an Australian statistician, who is part of a study to guide efforts for saving the Indonesian primate. ... > full story

Microorganisms in the ground don’t slack off in winter (November 20, 2010) -- It is known that soil microorganisms can maintain some activity during the cold winter months. Scientist have now shown that the microorganisms in frozen soils are much more viable than previously anticipated and also has large potential for growth. ... > full story

Designing more effective anti-HIV antibodies (November 20, 2010) -- Although people infected with HIV produce many antibodies against the protein encapsulating the virus, most of these antibodies are strangely ineffective at fighting the disease. A new study suggests why some of the most common of these antibodies don't work: they target the protein in a form it takes after the virus has already invaded the cell, when it's too late, report researchers. ... > full story

In fending off diseases, plants and animals are much the same, research shows (November 20, 2010) -- Contrary to long-held beliefs, plants and animals have developed remarkably similar mechanisms for detecting microbial invasions. This holds promise for the future treatment of infectious diseases in humans. ... > full story

Faster water flow means greater diversity of invertebrate marine life (November 20, 2010) -- On the rocks just beneath the tides, the faster the water is moving in an area, the greater the variety of invertebrate creatures that will live there. Understanding that water flow is a strong predictor of diversity could be a huge boon to efforts to manage coastal ecosystems. ... > full story

Detroit's urban farms could provide a majority of produce for local residents (November 20, 2010) -- Transforming vacant urban lots into farms and community gardens could provide Detroit residents with a majority of their fruits and vegetables. As city officials ponder proposals for urban farms, a new study indicates that a combination of urban farms, community gardens, storage facilities and hoop houses -- greenhouses used to extend the growing season -- could supply local residents with more than 75 percent of their vegetables and more than 40 percent of their fruits. ... > full story

Busy microbial world discovered in deepest ocean crust ever explored (November 19, 2010) -- The first study to ever explore biological activity in the deepest layer of ocean crust has found bacteria with a remarkable range of capabilities, including eating hydrocarbons and natural gas, and "fixing" or storing carbon. ... > full story

Pomegranate juice reduces damage to tissues, inflammation and infections, study suggests (November 19, 2010) -- Studies in recent years have claimed multiple health benefits of pomegranate juice, including that it is a good source of antioxidants and lowers both cholesterol and blood pressure, especially in diabetic and hypertensive patients. A preliminary study now suggests that it can ward off a number of complications in kidney disease patients on dialysis, according to new study. ... > full story

E. coli infection linked to long-term health problems (November 19, 2010) -- People who contract gastroenteritis from drinking water contaminated with E coli are at an increased risk of developing high blood pressure, kidney problems and heart disease in later life, finds a new study. ... > full story

New disease-resistant food crops under development (November 19, 2010) -- Researchers have uncovered the genetic basis of remarkable broad-spectrum resistance to a viral infection that, in some parts of the world, is the most important pathogen affecting leafy and arable brassica crops including broccoli, cauliflower, cabbage, kale, swede and oilseed rape. They have tested resistant plants against a range of different strains of the virus taken from all over the world and so far, no strain has been able to overcome the resistance. ... > full story

Paw prints and feces offer new hope for saving tigers (November 19, 2010) -- How many tigers are left in the wild can now be monitored accurately from their paw prints and scat (feces), ecologists have shown for the first time. The new technique at last gives conservationists a low-cost and reliable way of assessing tiger numbers, information that is crucial to saving the species from extinction in the wild. ... > full story

Chemicals' study pinpoints threat to workers' lungs (November 19, 2010) -- Tiny particles used in a range of everyday products from computers to shampoo can adversely affect the lungs in very different ways, a study has shown. Research suggests that industrial manufacturers using nanoparticles should be aware of the risks that different types of nanoparticles pose to workers who handle them. ... > full story
