Accurate Speedometer For Astronomy: Determining Velocities Of Stars And Other Celestial Bodies Posted: 14 Sep 2008 07:00 PM CDT There is now a new method for determining the velocities of stars and other celestial bodies which is a thousand times more accurate than previous methods.

Seeing Through The Skin: Optic-less Imaging Technology Could Beat Lens-based Imaging Devices Posted: 14 Sep 2008 07:00 PM CDT Feeling blue? According one researcher, humans may have an ability to "see" colors and shapes with their skin. His optic-less imaging model could lead to a new form of optical imaging technology that beats the limitations of today's lens-based imaging devices, and it may also explain how this controversial primordial instinct might have evolved over millions of years.

How Not To Gain The Dreaded 'Freshman Fifteen' Posted: 14 Sep 2008 07:00 PM CDT When fall classes at the University of California, San Diego begin on Sept. 25, freshmen will be on their own for the first time to spend endless hours on the computer, play video games and eat whatever they want, a recipe for weight gain. However, several UC San Diego wellness, weight-management and counseling programs will help students beat the dreaded "freshmen fifteen."

Say 'Goodbye' To Back Fat Rolls Posted: 14 Sep 2008 07:00 PM CDT A new study in Plastic and Reconstructive Surgery reveals a new back lift procedure that removes the unsightly bumps and bulges of back fat rolls while hiding the scar under the bra line.

Physicists Harness Effects Of Disorder In Magnetic Sensors Posted: 14 Sep 2008 07:00 PM CDT Scientists have discovered how to make magnetic sensors capable of operating at the high temperatures that ceramic engines in cars and aircraft of the future will require. The key to fabricating the sensors involves slightly degrading samples of a well-known semiconductor material, called indium antimonide, which is valued for its purity.

Immunity Traits May Be Involved In Mate Choice In Some Human Populations Posted: 14 Sep 2008 07:00 PM CDT Some human populations may rely on biological factors in addition to social factors when selecting a mate. Scientists have reported genomic data showing that immunity traits may be involved in mate choice in some human populations.

Old Growth Forests Are Valuable Carbon Sinks Posted: 14 Sep 2008 01:00 PM CDT Contrary to 40 years of conventional wisdom, a new analysis suggests that old growth forests are usually "carbon sinks" -- they continue to absorb carbon dioxide from the atmosphere and mitigate climate change for centuries.

Key Component Of Debilitating Lung Disease Identified Posted: 14 Sep 2008 01:00 PM CDT Antioxidant defense system could be new target for potential therapies for COPD. For the first time, researchers have demonstrated a close correlation between the decline in a key component of the lung's antioxidant defense system and the progression of chronic obstructive pulmonary disease (COPD) in humans.

Photos Reveal Myanmar's Large And Small Predators Posted: 14 Sep 2008 01:00 PM CDT Using remote camera traps to lift the veil on Myanmar's dense northern wild lands, researchers from the Wildlife Conservation Society have painstakingly gathered a bank of valuable data on the country's populations of tigers and other smaller, lesser known carnivores (see photo attachments). These findings will help in the formulation of conservation strategies for the country's wildlife.

Erectile Dysfunction Related To Sleep Apnea May Persist, But Is Treatable Posted: 14 Sep 2008 01:00 PM CDT For sufferers of sleep apnea, erectile dysfunction is often part of the package. New research indicates that ED in cases of obstructive sleep apnea syndrome may be linked to the chronic intermittent hypoxia -- oxygen deprivation -- that patients with OSAS experience during episodes of obstructed breathing.

Prototype Superconductor For Tokamak Fusion Reactor Proves Successful Posted: 14 Sep 2008 01:00 PM CDT Fusion for Energy (F4E) with the support of the European Commission, Japan Atomic Energy Agency (JAEA) and ITER Organisation have successfully tested a prototype superconductor for the ITER Poloidal Field coils made of Niobium(Nb)-Titanium(Ti) reaching a stable operation at 52 kA in a magnetic field of 6.4 Tesla. Poloidal Field coils will be used to maintain the plasma equilibrium and shape inside the ITER Tokamak reactor.

Illusion Vs. Reality: Age-related Differences In Expectations For Future Happiness Posted: 14 Sep 2008 01:00 PM CDT Albert Einstein once quipped, "Reality is merely an illusion, albeit a very persistent one." The famous scientist might have added that the illusion of reality shifts over time. According to a new study in the journal Psychological Science, age influences how we perceive the future.

New Cannabis-like Drugs Could Block Pain Without Affecting Brain, Says Study Posted: 14 Sep 2008 07:00 AM CDT A new type of drug could alleviate pain in a similar way to cannabis without affecting the brain, according to a new study in the journal Pain. The research demonstrates for the first time that cannabinoid receptors called CB2, which can be activated by cannabis use, are present in human sensory nerves in the peripheral nervous system, but are not present in a normal human brain.

Tuberculosis Drug Shows Promise Against Latent Bacteria Posted: 14 Sep 2008 07:00 AM CDT A new study has shown that an investigational drug, R207910, is quite effective at killing latent bacteria. This revelation suggests that R207910 may lead to improved and shortened treatments for this globally prevalent disease.

Photo Reveals Rare Okapi Survived Poaching Onslaught Posted: 14 Sep 2008 07:00 AM CDT A set of stripy legs in a camera trap photo snapped in an African forest indicates something to cheer about, say researchers from the Wildlife Conservation Society.

Osteoporosis: Calcium And Exercise To Strengthen The Bones -- Do You Get Enough? Posted: 14 Sep 2008 07:00 AM CDT A stumble, a fall -- a broken bone: many older people are afraid of this happening. The German Institute for Quality and Efficiency in Health Care has published information about how you can protect yourself. Research shows that regular adequate intake of calcium and exercise can strengthen the bones. But many people do not know whether they are getting enough calcium in their diets.

Closest Look Ever At Graphene: Stunning Images Of Individual Carbon Atoms From TEAM 0.5 Microscope Posted: 14 Sep 2008 07:00 AM CDT Hailed as the world's most powerful transmission electron microscope, TEAM 0.5 is living up to expectations. Using the microscope, researchers have produced stunning images of individual carbon atoms in graphene, the two-dimensional crystalline form of carbon that is highly prized by the electronics industry.

Making Snack Food Choices: Are Bad Intentions Stronger Than Good Intentions? Posted: 14 Sep 2008 07:00 AM CDT People who are asked whether they would choose between a "good" snack and a "bad" snack might not follow their intentions when the snacks arrive. Researchers found that there is a substantial inconsistency between healthful snack choice intentions and actual behavior.
