Interstellar Space Molecules That Help Form Basic Life Structures Identified (September 20, 2008) -- Scientists have succeeded in identifying naphthalene, one of the most complex molecules yet discovered in the interstellar medium. The detection of this molecule suggests that a large number of the key components in prebiotic terrestrial chemistry could have been present in the interstellar matter from which the Solar System was formed. ... > full story
Longevity, Cancer And Diet Connected: New Research In Worms Could Apply To Humans (September 20, 2008) -- Researchers have discovered a connection between genes that could hold the key to a longer, healthier life. Using worms that share similar genetics to humans, scientists have identified a previously unknown link between two genes -- one associated with aging, the other with certain types of cancer. ... > full story
Easier-to-hit 'Targets' Could Help Older People Make The Most Of Computers (September 20, 2008) -- Older people could make better use of computers if icons, links and menu headings automatically grew bigger as the cursor moves towards them. ... > full story
Stem Cells May Solve Mystery Of Early Pregnancy Breast Cancer Protection (September 20, 2008) -- The answer to why an early pregnancy seems to protect against breast cancer could rest with a decrease in stem cells found after animals have given birth, said researchers in a report in the journal Stem Cell. ... > full story

Emergence Of Agriculture In Prehistory Took Much Longer, Genetic Evidence Suggests (September 20, 2008) -- Researchers have found evidence that genetics supports the idea that the emergence of agriculture in prehistory took much longer than originally thought. ... > full story
Programmed Cell Death Contributes Force To Movement Of Cells (September 20, 2008) -- In addition to pruning cells out of the way during embryonic development, the much-studied process of programmed cell death, or apoptosis, has been newly found to exert significant mechanical force on surrounding cells. ... > full story
Prosthetic Vein Valve Designed To Direct Blood Flow Shows Promising Pre-clinical Results (September 20, 2008) -- Engineers have developed a prosthetic vein valve to help improve the lives of those suffering from a condition known as chronic venous insufficiency. The valve was designed to replace damaged, non-functioning valves. ... > full story
Sole Use Of Impaired Limb Improves Recovery In Spinal Cord Injury (September 20, 2008) -- A new study finds that following minor spinal cord injury, rats that had to use impaired limbs showed full recovery due to increased growth of healthy nerve fibers and the formation of new nerve cell connections. These findings help explain how physical therapy advances recovery, and support the use of rehabilitation therapies that specifically target impaired limbs in people with brain and spinal cord injuries. ... > full story
Optical Sensors Make MRI Scans Safer (September 20, 2008) -- Magnetic resonance scans will be safer for children and other patients needing anaesthesia, thanks to new kinds of optical sensors. ... > full story
Collaboration Helps Police Address Job Stress (September 20, 2008) -- Mangled bodies, gunfire, high-speed chases and injured children are just a few events witnessed by police officers and soldiers serving in dangerous hot spots around the world. These traumas take a high toll on the police officers and soldiers, who suppress human emotions to get the job done and can be reluctant to share their experiences in an effort to spare others from their ordeals, according to a September Police Quarterly article. ... > full story
