Could new flu spark global flu pandemic? New bird flu strain seen adapting to mammals, humans Posted: 12 Apr 2013 04:24 PM PDT A genetic analysis of the avian flu virus responsible for at least nine human deaths in China portrays a virus evolving to adapt to human cells, raising concern about its potential to spark a new global flu pandemic.

Compact multipurpose scooter for crowded megacities Posted: 12 Apr 2013 11:38 AM PDT Researchers have unveiled an all-new multipurpose scooter prototype, codenamed VOI, at the 3rd Taiwan International Electric Vehicle Show. VOI gets its name from the Vietnamese word for elephant -- a symbol of a safe and intelligent mean of transport. It is a two-wheel concept vehicle.

New device could cut costs on household products, pharmaceuticals Posted: 12 Apr 2013 11:37 AM PDT A new procedure that thickens and thins fluid at the micron level could save consumers and manufacturers money, particularly for soap products that depend on certain molecules to effectively deal with grease and dirt.

Arctic nearly free of summer sea ice during first half of 21st century, experts predict Posted: 12 Apr 2013 11:28 AM PDT For scientists studying summer sea ice in the Arctic, it's not a question of "if" there will be nearly ice-free summers, but "when." And two scientists say that "when" is sooner than many thought -- before 2050 and possibly within the next decade or two.

Scientists map elusive 3-D structure of telomerase enzyme, key actor in cancer, aging Posted: 12 Apr 2013 10:24 AM PDT Like finally seeing the gears of a watch and how they work together, all components of an entire telomerase enzyme complex have been positioned into a three-dimensional structure for the first time. This first complete visual map of the telomerase enzyme complex, known to play a significant role in cancer and aging, is a breakthrough from biochemists.

Reactivating memories during sleep: Memory rehearsal during sleep can make a big difference in remembering later Posted: 12 Apr 2013 10:24 AM PDT Why do some memories last a lifetime while others disappear quickly? A new study suggests that memories rehearsed, during sleep or waking, can have an impact on memory consolidation and on what is remembered later. A new study shows that when the information that makes up a memory has a high value, the memory is more likely to be rehearsed and consolidated during sleep and remembered later.

Secrets of bacterial slime revealed Posted: 12 Apr 2013 10:24 AM PDT Scientists have revealed the mechanism that causes a slime to form, making bacteria hard to shift and resistant to antibiotics.

Scientists use 'the force' (atomic force microscopy) to decode secrets of our gut Posted: 12 Apr 2013 10:24 AM PDT A new technique based on atomic force microscopy was developed to help "read" information encoded in proteins that make up the mucus layer that lines our gut.

Clues to heart disease in unexpected places Posted: 12 Apr 2013 10:24 AM PDT A major factor in the advance of heart disease is the death of heart tissue, a process that a team of scientists think could be prevented with new medicines.

Alternative way to explain life's complexity proposed Posted: 12 Apr 2013 10:24 AM PDT Evolution skeptics argue that some biological structures, like the eye, are too complex for natural selection to explain. Biologists have proposed various ways that so-called "irreducibly complex" structures could emerge incrementally over time. But a new study proposes an alternative route.

Disappearing nannies force parents to accept their duties Posted: 12 Apr 2013 10:24 AM PDT Large helpers (nannies) in a cichlid fish allow the dominant male and female to reduce their personal contribution to their offspring and territory, according to new research.

Carbon dioxide removal can lower costs of climate protection Posted: 12 Apr 2013 10:24 AM PDT Directly removing carbon dioxide from the air has the potential to alter the costs of climate change mitigation. It could allow prolonging greenhouse-gas emissions from sectors like transport that are difficult, thus expensive, to turn away from using fossil fuels. And it may help to constrain the financial burden on future generations, a new study shows.

Teenage smoking behavior influenced by friends' and parents' smoking habits Posted: 12 Apr 2013 10:24 AM PDT The company you keep in junior high school may have more influence on your smoking behavior than your high school friends, according to newly published research.

L-carnitine significantly improves patient outcomes following heart attack, study suggests Posted: 12 Apr 2013 10:23 AM PDT L-carnitine significantly improves cardiac health in patients after a heart attack, say a multicenter team of investigators in a study. Their findings, based on analysis of key controlled trials, associate L-carnitine with significant reduction in death from all causes and a highly significant reduction in ventricular arrhythmias and anginal attacks following a heart attack, compared with placebo or control.

Exercise or make dinner? Study finds adults trade one healthy act for another Posted: 12 Apr 2013 10:22 AM PDT American adults who prepare their own meals and exercise on the same day are likely spending more time on one of those activities at the expense of the other, a new study suggests.

Study on patients with disc prolapse: Same gene variant promotes pain in women, suppresses pain in men Posted: 12 Apr 2013 05:45 AM PDT More women than men develop chronic low back pain and sciatica. The explanation may lie with a gene variant that plays into the body's pain regulation.

Asbestos exposure, asbestosis, and smoking combined greatly increase lung cancer risk Posted: 12 Apr 2013 05:42 AM PDT The chances of developing lung cancer associated with asbestos exposure, asbestosis and smoking are dramatically increased when these three risk factors are combined, and quitting smoking significantly reduces the risk of developing lung cancer after long-term asbestos exposure, according to a new study.

Are human genes patentable? Posted: 12 Apr 2013 05:42 AM PDT On April 15, the Supreme Court of the United States will hear oral argument in Association for Molecular Pathology v. Myriad Genetics, a case that could answer the question, "Under what conditions, if any, are isolated human genes patentable?". Experts say the layered uncertainties make this case an unusually difficult case in which to predict the outcome.

Bad behavior in kids with hearing implants doesn't predict slowed language development Posted: 12 Apr 2013 05:42 AM PDT A new study is challenging a long held belief among speech therapists and audiologists that bad behavior in young children with hearing implants is an indicator of device failure and a predictor of poor language development.

Romantic comedies affect beliefs about relationships less strongly than expected Posted: 12 Apr 2013 05:42 AM PDT Romantic-comedy films are not a major source for developing unrealistic expectations about relationships among young adults, finds a new study to be published online this week in the National Communication Association's journal Communication Monographs.

Novel surface marker helps scientists 'fish out' mammary gland stem cells Posted: 11 Apr 2013 04:49 PM PDT It is now possible to profile normal and cancerous mammary stem cells at an unprecedented high degree of purity. This may help identify genes that should be investigated as the next breast cancer drug targets.

New research examines the spiritual, psychological and other under-appreciated effects of opioids on patients with sickle cell disease Posted: 11 Apr 2013 04:42 PM PDT Researchers sought to shed light on the biopsychosocial and spiritual effects of taking prescribed opioids to treat noncancer pain. Such questions have received little examination and impact the challenging decision of when and how to use opioids, the study authors said. They found that taking opioids had many and diverse consequences for patients in terms of biological, psychological, social and spiritual functioning.

Why do people with apple-shaped bodies have an increased risk of kidney disease? Posted: 11 Apr 2013 04:40 PM PDT People with apple-shaped bodies tend to have lower kidney function, lower kidney blood flow, and higher blood pressure within the kidneys than people with pear-shaped bodies. The findings may help explain why people with apple-shaped bodies are more likely than those with pear-shaped bodies to develop kidney disease.

Soy-based compound may reduce tumor cell proliferation in colorectal cancer Posted: 11 Apr 2013 04:40 PM PDT Scientists have developed a soy-based treatment for colorectal cancer, a promising agent in ovarian cancer, and a new drug target for advanced prostate cancer.

Pain improves during first year but mental-health problems linger in returning veterans with major limb injuries Posted: 11 Apr 2013 04:40 PM PDT Few studies document short- and long-term pain and behavioral health in combat-injured service members with major limb trauma.
