Washing Hands Properly Helps Stop Spread Of Contagious Diseases Posted: 08 Jun 2009 11:00 AM PDT We all know that coughs and sneezes spread diseases -- and that we should wash our hands to prevent passing on nasty viruses and bacteria. But how many of us just flick our hands under a dribbling tap and think that will do? Now hopeless hand washers will be caught -- not red-handed, but with glowing green fingers, by a new good hand washing test. |
Flexible Solar Power Shingles Transform Roofs From Wasted Space To Energy Source Posted: 08 Jun 2009 08:00 AM PDT A transparent thin film barrier used to protect flat panel TVs from moisture could become the basis for flexible solar panels that would be installed on roofs like shingles. |
New Lead For Autoimmune Disease From Chinese Medicine Posted: 08 Jun 2009 08:00 AM PDT A major challenge in treating autoimmune disorders has been suppressing inflammatory attacks on body tissues without generally suppressing immune function. Now, a drug from Chinese medicine shows potential for easing these disorders. In both mice and humans, it selectively inhibits development of Th17 cells, newly-recognized immune cells that were recently implicated in inflammatory bowel disease, rheumatoid arthritis, multiple sclerosis, type 1 diabetes, eczema and psoriasis. It also eased a multiple-sclerosis-like autoimmune disease in mice. |
Midge Keeps Invasive Mosquito In Check, Aiding Native Mosquitoes Posted: 08 Jun 2009 08:00 AM PDT The larvae of a tiny fly can influence the fate of native and invasive mosquitoes, with implications for human health. |
Stem Cell Protein Offers A New Cancer Target Posted: 08 Jun 2009 08:00 AM PDT Stem cell researchers have shown that a protein that keeps embryonic stem cells in their stem-like state, called LIN28, is also important in cancer. It offers a new target to attack, especially in resistant and hard-to-treat cases. |
New Center Aims To Improve Recovery Of Soldiers With Severe Injuries Posted: 08 Jun 2009 08:00 AM PDT When a soldier is wounded during combat, surgeons must focus on reducing infection and reconstructing damaged bone and tissues. Technologies that could improve the repair and regeneration processes are being developed in research laboratories across the country, but they are not being moved quickly enough into military trauma centers. Organizers of the recently established Georgia Tech Center for Advanced Bioengineering for Soldier Survivability want to change that. |
Asthma Rates And Where You Live Posted: 08 Jun 2009 08:00 AM PDT A new study shows how neighborhood characteristics play a significant role in childhood asthma. |
Fatty Foods -- Not Empty Stomach -- Fire Up Hunger Hormone Posted: 08 Jun 2009 05:00 AM PDT New research suggests that the hunger hormone ghrelin is activated by fats from the foods we eat -- not those made in the body -- in order to optimize nutrient metabolism and promote the storage of body fat. |
Brain Irradiation In Lung Cancer Posted: 08 Jun 2009 05:00 AM PDT Scientists have found that a course of radiation therapy to the brain after treatment for locally advanced non-small cell lung cancer reduced the risk of metastases to the brain within the first year after treatment. |
Skin Lesion Leads To More Cancer Types Than Once Believed Posted: 08 Jun 2009 05:00 AM PDT Dermatologists have found that sun-damaged rough patches on the skin known as actinic keratoses lead to more forms of skin cancer than previously thought. They also determined that lesions can become invisible and resurface over time. |
The Immune Response To Influenza Virus Isn't 'All Good' Posted: 08 Jun 2009 05:00 AM PDT How infection with influenza virus makes an individual sensitive to pneumonia-causing bacterial infections is clinically important but not well understood. New research now indicates that key mediators of the antiviral immune response initiated by infection with influenza virus impair the ability of mice to mount an adequate immune response to subsequent pneumonia-causing bacterial infection. These data might provide a new avenue of research for those developing ways to combat pneumonia following infection with influenza virus. |
3-D Structure Of Key Nuclear Pore Building Block Identified Posted: 08 Jun 2009 05:00 AM PDT New research into the molecular machine that filters all information traveling in or out of the cell nucleus contributes to an unfolding picture of cellular evolution that shows a common architecture for the nuclear pore complex and the vehicles that transport material between different parts of the cell. Scientists have for the first time glimpsed in three dimensions the subcomplex of the NPC that is its key building block. |
Risks Of Sharing Personal Genetic Information Online Need More Study, Bioethicists Say Posted: 08 Jun 2009 05:00 AM PDT With just $399 and a bit of saliva in a cup, consumers can learn about their genetic risk for diseases from breast cancer to diabetes. Now, thanks to social networking sites set up by personal genomics companies, they can also share that information with family, friends and even strangers on the Internet. Bonding over a similar genetic background sounds relatively harmless. But according to bioethicists sharing genetic information online raises a host of ethical questions. |
