Tropics: Global warming likely to significantly affect rainfall patterns (February 28, 2010) -- Ocean temperature patterns in the tropics and subtropics will change in ways that will lead to significant changes in rainfall patterns, according to new research. ... > full story
Choking is a leading cause of injury and death among children (February 28, 2010) -- Choking is a leading cause of injury and death among children, especially those younger than 4 years of age. The majority of choking-related incidents among children are associated with food, coins and toys. ... > full story
New process yields high-energy-density, plant-based transportation fuel (February 28, 2010) -- A team of engineers has developed a highly efficient, environmentally friendly process that selectively converts gamma-valerolactone, a biomass derivative, into the chemical equivalent of jet fuel. ... > full story
Large Earthquake Hits Chile, Generates Tsunami Across Pacific (February 27, 2010) -- An 8.8 magnitude earthquake struck off the coast of central Chile early morning on Saturday, February 27, 2010, about 200 miles southwest of the Chilean capital of Santiago, killing several hundred people and exposing millions of people to strong shaking that toppled many buildings. In addition, a tsunami triggered by the earthquake reverberated through the entire Pacific Ocean. ... > full story
Dolphin cognitive abilities raise ethical questions, says Emory neuroscientist (February 27, 2010) -- Many modern dolphin brains are significantly larger than those of humans and second in mass to the human brain when corrected for body size, says a scientist. Some dolphin brains exhibit features correlated with complex intelligence, including a large expanse of neocortical volume that is more convoluted than that of humans, extensive insular and cingulated regions, and highly differentiated cellular regions. This has ethical and policy considerations. ... > full story
Fueling the future with fish tank residue: Scientist discusses use of algae as biofuel (February 27, 2010) -- As Americans demand new and cleaner ways to meet the country's energy needs, researchers are turning to algae as a promising new fuel source. The approach has the potential to significantly reduce the nation's reliance on imported oil while contributing to rural economic development and lowering greenhouse emissions. ... > full story
Climate change and coral reefs: Coral species has developed the 'skills' to cope with rising temperatures (February 27, 2010) -- Marine reserves are increasingly important for species that are being forced by climate change to move to a new home, adapt to new conditions or die. Biologists have now compared the relative benefits of large and small protected areas in perpetuating populations. Interestingly they have also found a coral species that has developed the "skills" to cope with rising temperatures. ... > full story
Flower power may reduce resistance to breast cancer drug tamoxifen (February 27, 2010) -- Combining tamoxifen, the world's most prescribed breast cancer agent, with a compound found in the flowering plant feverfew may prevent initial or future resistance to the drug, say researchers. The finding provides new insight into the biological roots of that resistance, and also tests a novel way to get around it. ... > full story
Malicious software: Hiding the honeypots (February 27, 2010) -- Armies of networked computers that have been compromised by malicious software are commonly known as Botnets. Such Botnets are usually used to carry out fraudulent and criminal activity on the Internet. Now US computer scientists reveal that the honeypot trap designed to protect computers from Botnets are now vulnerable to attack because of advances in Botnet malware. ... > full story
Threat to monkey numbers from forest decline (February 27, 2010) -- Monkey populations in threatened forests are far more sensitive to damage to their habitat than previously thought. Numbers closely related to the type of habitat found between forest fragments, rather than the distance that separates them. ... > full story
Intelligent energy management for the home (February 27, 2010) -- In order to save energy, consumers need to be able to obtain up-to-date information at any time about the energy consumption of their appliances, and be able to control them while away from home. Scientists have developed two new applications that help consumers manage their power use. ... > full story
Presence of snails points to forest recovery (February 27, 2010) -- Researchers have studied the changes in the make-up of animal populations following forest fires, and have concluded that malacological fauna are a good indicator of forest recovery. The conclusions of this study will help to ensure that post-fire forestry operations that do not harm these species of mollusks, which are sensitive to microclimatic conditions of the soil and vegetation structure. ... > full story
