New Model Predicts A Glacier's Life (October 31, 2008) -- Researchers have developed a numerical model that can re-create the state of Switzerland's Rhône Glacier as it was in 1874 and predict its evolution until the year 2100. This is the longest period of time ever modeled in the life of a glacier, involving complex data analysis and mathematical techniques. The work will serve as a benchmark study for those interested in the state of glaciers and their relation to climate change. ... > full story
Extinct Sabertooth Cats Were Social, Found Strength In Numbers, Study Shows (October 31, 2008) -- The sabertooth cat, one of the most iconic extinct mammal species, was likely to be a social animal, living and hunting like lions today, according to new scientific research. The species is famous for its extremely long canine teeth, which reached up to seven inches in length and extended below the lower jaw of the cat. ... > full story
Over-use Of Organic Fertilizers In Agriculture Could Poison Soils, Study Finds (October 31, 2008) -- Excessive doses of organic residues in agricultural fields could be dangerous for plants, invertebrates and micro-organisms living in the soil. This is the finding of a new study that shows that the use of appropriate levels of fertilizers would prevent this toxic impact on the soil biota. ... > full story
By Imaging Live Cells, Researchers Show How Hepatitis C Replicates (October 31, 2008) -- The hepatitis C virus is a prolific replicator, able to produce up to a trillion particles per day in an infected person by hijacking liver cells in which to build up its viral replication machinery. Now new research -- in which scientists have for the first time used fluorescent proteins to image hepatitis C virus replication in live cells -- shows that the microscopic viral factories are a diverse mix of big, immobile structures and tiny replication complexes that zip zanily around inside the cell. ... > full story
In Decision To Grow, Bacteria Follow The Crowd (October 31, 2008) -- When it comes to the decision to wake up and grow, bacterial spores "listen in" to find out what their neighbors are doing and then they follow the crowd, according to a new report. ... > full story
'Living Fossil' Tree Contains Genetic Imprints Of Rain Forests Under Climate Change (October 31, 2008) -- A "living fossil" tree species is helping a researcher understand how tropical forests responded to past climate change and how they may react to global warming in the future. ... > full story
Grapes May Aid A Bunch Of Heart Risk Factors, Animal Study Finds (October 31, 2008) -- Could eating grapes help fight high blood pressure related to a salty diet? And could grapes calm other factors that are also related to heart diseases such as heart failure? A new study performed in animals suggests so. ... > full story
Evidence Of Tsunamis On Indian Ocean Shores Long Before 2004 (October 31, 2008) -- A quarter-million people were killed when a tsunami inundated Indian Ocean coastlines the day after Christmas in 2004. Now scientists have found evidence that the event was not a first-time occurrence. ... > full story
Pneumococcal Vaccine Could Prevent Numerous Deaths, Save Costs During A Flu Pandemic, Model Predicts (October 31, 2008) -- A new predictive model shows that vaccinating infants with 7 valent pneumococcal conjugate vaccine -- the current recommendation--not only saves lives and money during a normal flu season by preventing related bacterial infections; it also would prevent more than 357,000 deaths during an influenza pandemic, while saving billion in costs. ... > full story
Predicting Evolution’s Next Best Move With Simulator (October 31, 2008) -- Biologists today are doing what Darwin thought impossible. They are studying the process of evolution not through fossils but directly, as it is happening. Now, by modeling the steps evolution takes to build, from scratch, an adaptive biochemical network, biophysicists have gone one step further. Instead of watching evolution in action, they show that they can predict its next best move. ... > full story
Local Retail Meat Safe From Antibiotic-resistant Organisms, Study Suggests (October 31, 2008) -- Rhode Island Hospital researchers report that findings from a new study of retail meat in the Providence, RI area indicate little to no presence of antibiotic-resistant bacteria. The study, prompted by the identification of such organisms in retail meat in Canada, Europe and Asia, is among the first in this country to look at the possible spread of infection through retail meat. ... > full story
Mysterious Bat Disease Decimates Colonies: Newly Identified Fungus Implicated In White-nose Syndrome (October 31, 2008) -- White-nose syndrome in bats is a disease that is decimating bat populations in the northeast U.S. A previously undescribed, cold-loving fungus has been linked to white-nose syndrome, a condition associated with the deaths of over 100,000 hibernating bats in the northeastern United States. ... > full story
