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
Peptide Ghrelin May Be Involved In Both Alcohol Dependence And Overeating (September 26, 2008) -- Ghrelin is a peptide found mostly in the stomach but also in the brain. Ghrelin is known to have an effect on food intake by increasing feelings of hunger and the urge to eat. New findings show that the ghrelin system may also be involved in addictive behaviors and brain reward. ... > 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
Social Class Dictates Cancer Risk (September 26, 2008) -- Cervical and lung cancer are more common in poor people while rates of breast cancer and melanoma are higher in the wealthy. A detailed analysis of the incidence of these four different kinds of cancer, carried out on more than 300,000 English cancer patients and published in BMC Cancer, describes the effects of socioeconomic group, region and age. ... > 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
Diffusion Caused Jupiter's Red Spot Junior To Color Up (September 26, 2008) -- A study has given new insights into why Oval BA, a giant anticyclone on Jupiter also known as Red Spot Junior, suddenly turned from white to red in a period of just a few months. ... > full story
Weight Loss Surgery May Be Associated With Bone Loss (September 26, 2008) -- Weight loss surgery may be linked to deficiencies in calcium and vitamin D and bone loss, according to a new study. ... > 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
Post-traumatic Stress Experienced By Family Members Months After Loved One's Stay In Intensive Care Unit (September 26, 2008) -- Family members may experience post-traumatic stress as many as six months after a loved one's stay in a hospital's intensive care unit (ICU), according to a new study. The study found that symptoms of anxiety and depression in family members of ICU patients diminished over time, but high rates of post-traumatic stress and complicated grief remained. ... > full story
