Real-time Gene Monitoring Developed Posted: 27 Dec 2008 05:00 PM PST Imagine having GeneVision: the uncanny ability to view the activity of any chosen gene in real time through a specially modified camera. With GeneVision, military commanders could compare gene expression in victorious and defeated troops. Retailers could track genes related to craving as shoppers moved about a store. "The Bachelor" would enjoy yet one more secret advantage over his love-struck dates. A new study correlates real-time gene expression with movement and behavior for the first time.

New Anti-cancer Components Of Extra-virgin Olive Oil Revealed Posted: 27 Dec 2008 05:00 PM PST Good quality extra-virgin olive oil contains health-relevant chemicals, 'phytochemicals', that can trigger cancer cell death. New research sheds more light on the suspected association between olive oil-rich Mediterranean diets and reductions in breast cancer risk.

Ecosystem Changes In Temperate Lakes Linked To Climate Warming Posted: 27 Dec 2008 05:00 PM PST Unparalleled warming over the last few decades has triggered widespread ecosystem changes in many temperate North American and Western European lakes, say researchers.

Breathing Problems During Sleep Associated With Calories Burned At Rest Posted: 27 Dec 2008 05:00 PM PST Individuals with sleep-related breathing disorders appear to burn more calories when resting as their conditions become more severe, according to a new report.

Molecular Manual For Hundreds Of Inherited Diseases Developed Posted: 27 Dec 2008 05:00 PM PST Researchers have created a catalogue of tissue-specific processes involved in hundreds of inherited diseases. These results could help treat diseases such as breast cancer, Parkinson disease, heart diseases and autism.

Head And Neck Injury Risks In Heavy Metal: Head Bangers Stuck Between Rock And A Hard Bass Posted: 27 Dec 2008 05:00 PM PST Head banging increases the risk of head and neck injury, but the effects may be lessened with reduced head and neck motion, head banging to lower tempo songs or to every second beat, and using protective equipment such as neck braces, finds a new study.

Humans And Chimps Register Faces By Using Similar Brain Regions Posted: 27 Dec 2008 11:00 AM PST Chimpanzees recognize their pals by using some of the same brain regions that switch on when humans register a familiar face. The study -- the first to examine brain activity in chimpanzees after they attempt to match fellow chimps' faces -- offers new insight into the origin of face recognition in humans, the researchers said.

Killer Peptide May Offer New Therapy Against Influenza A Virus Posted: 27 Dec 2008 11:00 AM PST In a new study researchers identified what appears to be the first antibody-derived peptide that inhibits the activities of harmful microbes such as influenza A virus and HIV-1.

Warmer Temperatures Could Lead To A Boom In Corn Pests Posted: 27 Dec 2008 11:00 AM PST Climate change could provide the warmer weather pests prefer, leading to an increase in populations that feed on corn and other crops, according to a new study. Warmer growing season temperatures and milder winters could allow some of these insects to expand.

New Insight Into Birth Defect Characterized By Digit Duplication And Fusion Posted: 27 Dec 2008 11:00 AM PST Birth defects characterized by malformation of the limbs are relatively common. New insight into one form of the birth defect synpolydactyly, where individuals have 1 or more digit (finger or toe) duplicated and 2 or more digits fused together, has now been provided researchers in Germany who studied a mouse model of the condition.

Gesture Recognition Will Allow People With Disabilities To Interact More Easily With Computers Posted: 27 Dec 2008 11:00 AM PST A system that can recognize human gestures could provide a new way for people with physical disabilities to interact with computers. A related system for the able bodied could also be used to make virtual worlds more realistic.

Researchers Revisit Male Bisexuality Posted: 27 Dec 2008 11:00 AM PST While the Kinsey Scale has become a fixture in sexuality textbooks and even popular culture, the rating system and Alfred Kinsey's findings regarding male bisexuality and cultural influences on male sexuality in general have largely been overlooked by today's sex researchers.

New Titanium-glass Alloys Are Tough, Cheap And Light-weight Posted: 27 Dec 2008 05:00 AM PST Scientists have created a range of structural metallic-glass composites, based in titanium, that are lighter and less expensive than any the group had previously created, while still maintaining their toughness and ductility -- the ability to be deformed without breaking.

Phosphorus-lowering Drugs Linked To Lower Mortality In Dialysis Patients Posted: 27 Dec 2008 05:00 AM PST For patients on dialysis, taking medications to reduce levels of the mineral phosphorus in the blood may reduce the risk of death by 25 to 30 percent, reports a new study.

Just A Little Squeeze Lets Proteins Assess DNA Posted: 27 Dec 2008 05:00 AM PST To find its target, all a protein needs to do is give quick squeezes as it moves along the DNA strand, suggests new research. Scientists had thought DNA-binding proteins primarily used full-body hugs for accurate readings of the information coded in the DNA's sequence. Doing the quick squeezes that scientists call indirect readout probably works faster, the researchers said. The finding has implications for the development of designer drugs.

Colonoscopy Significantly Reduces Death From Left-sided Colon Cancer But Not From Right-sided Posted: 27 Dec 2008 05:00 AM PST A new study finds that colonoscopy is strongly associated with fewer deaths from colorectal cancer. However, the risk reduction appears to be entirely due to a reduction in deaths from left-sided cancers. According to the study, colonoscopy shows almost no mortality prevention benefit for cancer that develops in the right side of the colon.

No Quick Or Easy Technological Fix For Climate Change, Researchers Say Posted: 27 Dec 2008 05:00 AM PST Global warming can be reversed, some are arguing, with a "geoengineering" fix, such as flying a giant blimp and spraying liquefied sulfur dioxide in the stratosphere. But a professor in the UCLA Department of Atmospheric and Oceanic Sciences sees no evidence there is any quick or easy technological fix.

Fears Of Promiscuity Pose Barrier To Cervical Cancer Vaccinations Posted: 27 Dec 2008 05:00 AM PST The public's concerns about costs and increased promiscuity among teenagers appear to be hindering use of a vaccine against the human papilloma virus to prevent life-threatening diseases, according to a new study.
