| New Discovery Proves 'Selfish Gene' Exists Posted: 22 Jun 2008 07:00 PM CDT A new discovery provides conclusive evidence that the "selfish" gene does exist. In studying genomes, the word "selfish" does not refer to self-centered behavior but rather to the blind tendency of genes wanting to continue their existence into the next generation. Biologists have isolated a region on the honey bee genome that houses this "selfish" gene in female workers bees.  |
| Advance Towards Early Alzheimer's Diagnosis Posted: 22 Jun 2008 07:00 PM CDT An Australian research project has found a way to bring forward the detection of early stage Alzheimer's disease by up to 18 months. Alzheimer's disease is characterized by very high levels of a molecule called beta-amyloid in the brain.  |
| Sprinters Closest To Starter Pistol Have Advantage Over Those Farther Away, Says Study Posted: 22 Jun 2008 07:00 PM CDT "In sprint events, where hundredths of a second can make the difference between a gold medal and a silver, minimizing reaction time can be the key to an athlete's success. We suggest that procedures presently used to start the Olympic sprint events give runners closer to the starter the advantage of hearing the "go" signal louder; consequently, they react sooner than their competitors," says a researcher who has studied the question.  |
| Striving To Break The Link Between Obesity And Diabetes Posted: 22 Jun 2008 07:00 PM CDT Obesity and type 2 diabetes are inextricably linked, but biochemist and geneticist Ling Qi is working to break that connection. Finding just the right gene could do it, says one professor of nutritional sciences.  |
| Novel X-ray Source Could Be Brightest In The World Posted: 22 Jun 2008 07:00 PM CDT The future of high-intensity X-ray science has never been brighter now that scientists have devised a new type of next generation light sources. The oscillator is projected to increase the current brightness by millions of times.  |
| Addicted To Grief? Chronic Grief Activates Pleasure Areas Of The Brain Posted: 22 Jun 2008 07:00 PM CDT Most of us experience the grief associated with the loss of a loved one at some point in our lives. New research now suggests that people who never get over their loss, who never "let go," may be activating neurons in the reward centers of the brain, possibly giving these memories addiction-like properties.  |
| Birds Migrate Earlier, But Some May Be Left Behind As Climate Warms Rapidly Posted: 22 Jun 2008 01:00 PM CDT Many birds are arriving earlier each spring as temperatures warm along the East Coast of the United States. However, the farther those birds journey, the less likely they are to keep pace with the rapidly changing climate.  |
| Mom's High Fat Diet During Pregnancy May Be Key To Child's Weight Issues Posted: 22 Jun 2008 01:00 PM CDT The notion that you are what you eat may go back even farther -- to your mother, said a Baylor College of Medicine researcher in a report that appears in the current issue of the Journal of Molecular Endocrinology.  |
| Phoenix Mars Lander Delivers Soil Sample To Microscope Posted: 22 Jun 2008 01:00 PM CDT NASA's Phoenix Mars Lander Saturday beamed back images showing that Phoenix's Robotic Arm successfully sprinkled soil onto the delivery port of the lander's Optical Microscope.  |
| New Technology May Prevent Vitamin B12 Deficient Seniors And Vegetarians From Needing Injections Posted: 22 Jun 2008 01:00 PM CDT For those patients who receive the nearly 40 million intramuscular injections per year to treat their B12 deficiency, a new oral option may soon exist. According to the National Institutes of Health, vitamin B12 deficiency can lead to a wide spectrum of conditions, such as anemia, dementia and reduced cognitive functioning.  |
| Posted: 22 Jun 2008 01:00 PM CDT In many villages throughout Tibet, there are two ways to cook a meal. There's the traditional open fire, fueled by yak dung or the region's increasingly scarce wood. And then there are solar cookers, concentrating mirrors made of two-inch-thick concrete and covered with a mosaic of small glass mirrors.  |
| Poor Children More Likely To Develop Diabetes As Adults Posted: 22 Jun 2008 01:00 PM CDT Diabetes strikes harder at those who were poor as children, according to a new study that spans more than three decades. Participants who were disadvantaged in youth were more likely to develop diabetes than better-off peers were during the 34-year study time frame.  |
| Newly Born Twin Stars Are Far From Identical Posted: 22 Jun 2008 07:00 AM CDT The analysis of the youngest pair of identical twin stars yet discovered has revealed surprising differences in brightness, surface temperature and possibly even in size, suggesting that the stars formed at significantly different times rather than simultaneously as generally assumed.  |
| How Measles Virus Spreads: Discovery May Rewrite Textbooks Posted: 22 Jun 2008 07:00 AM CDT Measles, one of the most common contagious diseases, has been thought to enter the body through the surface of airways and lungs, like many other major viruses. Now, scientists say that's not the case, and some medical texts will have to be revised.  |
| Phoenix Mars Lander Confirms Frozen Water On Red Planet Posted: 22 Jun 2008 07:00 AM CDT Scientists relishing confirmation of water ice near the surface beside NASA's Phoenix Mars Lander anticipate even bigger discoveries from the robotic mission in the weeks ahead.  |
| Researchers See Alternative To Common Colorectal Cancer Drug Posted: 22 Jun 2008 07:00 AM CDT A compound that accumulates in cells more readily than a commonly used colorectal cancer drug may be just as useful in treating colorectal tumors, but with fewer side effects, researchers have found.  |
| Efficiency Experts Seek To Save Precious Minutes In Deploying Ambulances Posted: 22 Jun 2008 07:00 AM CDT Every extra second it takes an ambulance to get to its destination can mean life or death. But how, besides driving faster, can ambulances get emergency services to people in need as efficiently as possible, every day? It's a classic operations research question that three researchers are tackling in groundbreaking ways.  |
| Posted: 22 Jun 2008 07:00 AM CDT A researcher argues in Science that a basic tenet of economics -- that people always behave selfishly -- can be wrong, sometimes badly so. He points to new experimental evidence that people do often act against their own personal self-interest in favor of the common good, and they do so in predictable, understandable ways. Poorly-designed economic institutions fail to take advantage of intrinsic moral behavior and often undermine it.  |
| NASA Launches Ocean Satellite To Keep A Weather, Climate Eye Open Posted: 21 Jun 2008 11:00 PM CDT A new NASA-French space agency oceanography satellite launched today from Vandenberg Air Force Base, Calif., on a globe-circling voyage to continue charting sea level, a vital indicator of global climate change. The mission will return a vast amount of new data that will improve weather, climate and ocean forecasts.  |
