Possible biological control discovered for pathogen devastating amphibians (August 27, 2011) -- Zoologists have discovered that a freshwater species of zooplankton will eat a fungal pathogen which is devastating amphibian populations around the world. It could provide a desperately needed tool for biological control of this deadly fungus. ... > full story

Novel control of Dengue fever (August 27, 2011) -- The spread of Dengue fever in northern Australia may be controlled by a bacterium that infects mosquitoes that harbor the virus, researchers report. ... > full story

Molecular chaperones traffic signaling proteins between cells in plant stem-cell maintenance pathway (August 27, 2011) -- Plant biologists have discovered that proteins called chaperonins are an indispensable factor in making possible cell-to-cell trafficking of signals that maintain stem cells and enable plants to grow. ... > full story

Wide gap in immune responses of people exposed to the flu (August 27, 2011) -- Why do some folks who take every precaution still get the flu, while others never even get the sniffles? It comes down to a person's immune system response to the flu virus, according to new research. In one of the first known studies of its kind, researchers used genomics to begin to unravel what in our complex genomic data accounts for why some get sick while others don't. ... > full story

Florida's reefs cannot endure a 'cold snap' (August 27, 2011) -- Florida's corals dropped in numbers due to unseasonably cold weather conditions in 2010. The chilly January temperatures caused the most catastrophic loss of corals within the Florida Reef Tract, which spans 160 miles (260 kilometers) from Miami to the Dry Tortugas and is the only living barrier reef in the continental U.S. ... > full story

Summer drought limits the positive effects of CO<sub>2</sub> and heat on plant growth in future climate (August 27, 2011) -- Summer drought limits the positive effects of carbon dioxide and heat on plant growth in future climate. Although the rain this summer has been pouring down over Denmark, most scientists agree that global temperature increases will intensify periods with summer drought already in 2075. ... > full story

Could new drug cure nearly any viral infection? Technology shows promise against common cold, influenza and other ailments, researchers say (August 26, 2011) -- Most bacterial infections can be treated with antibiotics such as penicillin, discovered decades ago. However, such drugs are useless against viral infections, including influenza, the common cold, and deadly hemorrhagic fevers such as Ebola. Now, in a development that could transform how viral infections are treated, a team of researchers has designed a drug that can identify cells that have been infected by any type of virus, then kill those cells to terminate the infection. ... > full story

Cars could run on recycled newspaper, scientists say (August 26, 2011) -- Here's one way that old-fashioned newsprint beats the Internet. Scientists have discovered a novel bacterial strain, dubbed "TU-103," that can use paper to produce butanol, a biofuel that can serve as a substitute for gasoline. They are currently experimenting with old editions of the Times Picayune, New Orleans' venerable daily newspaper, with great success. ... > full story

Adapting to climate change with floating houses? (August 26, 2011) -- Climate change is redefining the rules by which we live and at a pace we never expected. Because of rising sea level, several areas of the globe are in danger of vanishing from the map, disappearing under water. Society must adapt and maybe, one day, live in floating houses in floating cities. ... > full story

Biological communities studied at historical WWII shipwrecks along North Carolina (August 26, 2011) -- In the waters off the North Carolina coast, historically-significant World War II submarines and shipwrecks rest on the seafloor, a testament to a relatively unknown chapter in US history. According to a new report, the shipwrecks are not only important for their cultural value, but also as habitat for a wide diversity of fishes, invertebrates and algal species. Additionally, due to their unique location within an important area for biological productivity, the shipwrecks are potential sites for examining community change. ... > full story

Heat in chili peppers can ease sinus problems, research shows (August 26, 2011) -- Hot chili peppers are known to make people "tear up," but a new study found that a nasal spray containing an ingredient derived from hot chili peppers may help people "clear up" certain types of sinus inflammation. ... > full story

Earth-bound asteroids come from stony asteroids, new studies confirm (August 26, 2011) -- Researchers got their first up-close look at dust from the surface of a small, stony asteroid after the Hayabusa spacecraft scooped some up and brought it back to Earth. Analysis of these dust particles confirms a long-standing suspicion: that the most common meteorites found here on Earth, known as ordinary chondrites, are born from these stony, or S-type, asteroids. ... > full story
