Tobacco and poverty drive cancer in developing world
December 20, 2007 04:17 PM - By Maggie Fox, Health and Science Editor, Reuters

WASHINGTON (Reuters) - Rising tobacco use and poverty will fuel cancer across the developing world, more than doubling the number of new cases to 27 million by 2050, experts predicted on Thursday. Cancer is already the No. 2 cause of death globally, after heart disease and ahead of AIDS, malaria, tuberculosis and other causes. And as people live longer and adopt bad habits such as smoking, cancer cases will rise, said Dr. Nancy Davidson of Johns Hopkins University in Baltimore.

EU ministers stall new soil protection rules
December 20, 2007 12:38 PM - Reuters

BRUSSELS (Reuters) - European Union environment ministers put new rules to protect soil in the bloc on a backburner on Thursday after a coalition led by Britain and Germany blocked the adoption of a draft law. The bill had sought to prevent the soil's deterioration from industrial use and the effects of climate change. It would have obliged the EU's 27 nations to set up public inventories of sites where soil may be contaminated with dangerous substances and lay out ways to clean them up. "There was a blocking minority against the soil directive. Maybe we will return to it in the future, but it is unclear when," an EU diplomat said. The diplomat said advocates of the planned law had failed to muster a qualified majority to adopt it when Britain, Germany France, Austria and the Netherlands voted against.

City of Pasadena Greenlights The Pasadena EcoHouse
December 20, 2007 12:00 PM -

PASADENA, Calif. - The Pasadena EcoHouse is a step closer to reality today, after the City of Pasadena approved the homeowners' hillside building permit at last night's meeting. When completed, The Pasadena EcoHouse will be the first single-family, structural concrete insulated panel (SCIP) home in the nation to earn the coveted Platinum certification by the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) for Homes Green Building Rating System(TM), as well as the first LEED Platinum home in Pasadena. To earn the Platinum rating, The Pasadena EcoHouse will score points in several categories, including design, location, site impact, water and energy efficiency, indoor air quality, and green building awareness and education.

Squirrels use snake scent
December 20, 2007 09:42 AM - University of California - Davis

California ground squirrels and rock squirrels chew up rattlesnake skin and smear it on their fur to mask their scent from predators, according to a new study by researchers at UC Davis. Barbara Clucas, a graduate student in animal behavior at UC Davis, observed ground squirrels (Spermophilus beecheyi) and rock squirrels (Spermophilus variegates) applying snake scent to themselves by picking up pieces of shed snakeskin, chewing it and then licking their fur.

"Virgin" birth stem cells may offer tissue bank

WASHINGTON (Reuters) - Human egg cells can be tweaked to give rise to valued stem cells that match the tissue types of many different groups of people, U.S. and Russian researchers reported on Wednesday. They said the stem cells they have created from unfertilized human eggs look and act like embryonic stem cells. And they have been carefully tissue-matched in the same way as bone marrow donations to prevent the risk of rejection if they are transplanted into people.

MINNEAPOLIS / ST. PAUL - A new study looks at a poorly understood process with potentially critical consequences for climate change. Emma Sayer, postdoctoral fellow at the Smithsonian Tropical Research Institute, Jennifer Powers, an assistant professor in the University of Minnesota's department of ecology, Evolution and Behavior, and Edmund Tanner, researcher at Cambridge University, published the findings of their long-term study on the effects of increased plant litter on soil carbon and nutrient cycling in the Dec. 12 edition of PLoS ONE.

Experts: Pricy Oil Will Push Renewable Fuels Development
December 19, 2007 03:02 PM - Paul Schaefer, ENN

MINNEAPOLIS / ST. PAUL - researchers at the University of Minnesota has discovered a silver lining in the increasing cost of oil. Midwest experts in research, government, business and nonprofit sectors who attended the university’s E3 conference last month were surveyed on what they think will promote sustainable energy research within their geographic domain. Forty percent of the respondents said the cost of oil is the primary driver.

MINNEAPOLIS / ST. PAUL - A new Web-based software program is the latest tool University of Minnesota researchers are using to help fight the spread of HIV. A multidisciplinary team of researchers, are embarking on a clinical trial this month to test a software program that aims to reduce risk-taking behavior associated with the spread of HIV and other sexually transmitted infections.

Scientiosts find origin of “breathable” atmosphere half a billion years ago
December 19, 2007 12:46 PM - Ohio State University Newswire

COLUMBUS , Ohio -- Ohio State University geologists and their colleagues have uncovered evidence of when Earth may have first supported an oxygen-rich atmosphere similar to the one we breathe today. The study suggests that upheavals in the earth's crust initiated a kind of reverse-greenhouse effect 500 million years ago that cooled the world's oceans, spawned giant plankton blooms, and sent a burst of oxygen into the atmosphere. That oxygen may have helped trigger one of the largest growths of biodiversity in Earth's history.
