Bees Can Mediate Escape Of Genetically Engineered Material Over Several Kilometers (September 27, 2008) -- Bees have the potential to mediate the escape of transgenes (genetically engineered material) from crops to their wild relatives over several kilometers. The findings bear significant implications for the introduction of genetically modified crops in Africa. ... > full story
Mother Of A Goose! Giant Ocean-going Geese With Bony-teeth Once Roamed Across SE England (September 27, 2008) -- A 50 million year old skull reveals that huge birds with a 5 meter wingspan once skimmed across the waters that covered what is now London, Essex and Kent. These giant ocean-going relatives of ducks and geese also had a rather bizarre attribute for a bird: their beaks were lined with bony-teeth. ... > full story
From One Laying To Another, The Female Collembolan Adapts Its Eggs To Environmental Constraints (September 27, 2008) -- Reproductive plasticity -- the ability of individuals to modify their reproduction and the characteristics of their progeny according to environmental or social conditions -- is a crucial factor in the demographics of animal populations, including man. Scientists have now demonstrated the adaptive nature of the reproductive behavior of certain arthropods from one laying to another, in the same female. ... > full story
Captive Breeding Introduced Infectious Disease To Mallorcan Amphibians (September 27, 2008) -- A potentially deadly fungus that can kill frogs and toads was inadvertently introduced into Mallorca by a captive breeding program that was reintroducing a rare species of toad into the wild, according to a new study in the journal Current Biology. ... > full story
Want Better Mileage? Simple Device Which Uses Electrical Field Could Boost Gas Efficiency Up To 20% (September 26, 2008) -- A simple device which attaches to a vehicles fuel line near the fuel injector and creates an electrical field could boost gas efficiency as much as 20 percent. ... > full story
Animals Farmed For Meat Are The No. 1 Source Of Food Poisoning Bug, Study Shows (September 26, 2008) -- A study, based on DNA-sequence comparison of thousands of bacterial samples collected from human patients and animal carriers, found that 97 percent of campylobacteriosis cases sampled in Lancashire, UK, were caused by bacteria typically found in chicken and livestock. ... > full story
Australian Frog Species Chooses Not To Put Eggs In One Basket (September 26, 2008) -- A new study into the mating and nesting practices of a common Australian frog has found they partner up to eight males sequentially -- the highest recorded of any vertebrate. ... > full story
New More Efficient Ways To Use Biomass (September 26, 2008) -- Researchers have developed a new catalyst that directly converts cellulose, the most common form of biomass, into ethylene glycol, an important intermediate product for chemical industry. ... > full story
Earth's Magnetic Field Reversals Illuminated By Lava Flows Study (September 26, 2008) -- Earth's north magnetic pole is shifting and weakening. Ancient lava flows are guiding a better understanding of what generates and controls the Earth's magnetic field -- and what may drive it to occasionally reverse direction. Current evidence suggests we are now approaching a transitional state because the main magnetic field is relatively weak and rapidly decreasing, researchers say. While the last polarity reversal occurred several hundred thousand years ago, the next might come within only a few thousand years. ... > full story
Scientists Unmask Key HIV Protein, Open Door For More Powerful AIDS Drugs (September 26, 2008) -- Scientists have provided the most detailed picture yet of a key HIV accessory protein that foils the body's normal immune response. Based on the findings, the team is searching for new drugs that may someday allow infected people to be cured and no longer need today's AIDS drugs for a lifetime. ... > full story
Photonic Crystal Biosensors Detect Protein-DNA Interactions (September 26, 2008) -- Scientists have developed a new class of disposable, microplate-based optical biosensors capable of detecting protein-DNA interactions. Based on the properties of photonic crystals, the biosensors are suitable for the rapid identification of inhibitors of protein-nucleic acid and protein-protein interactions. ... > full story
Pigs Bred With Cystic Fibrosis Provide Model To Mimic Human Disease (September 26, 2008) -- Cystic fibrosis continues to be a lethal disease for humans despite the identification of the problematic gene two decades ago. Many humans born with CF -- the most common genetic disease in Caucasians -- often die because of a lung disease developed later. Scientists have been unable to develop an animal model that develops the fatal lung disease. Now, one researcher is producing pigs born with cystic fibrosis that mimic the exact symptoms of a newborn with CF. ... > full story
