Fish shed light on human melanoma Posted: 15 Jun 2012 05:46 PM PDT Zebrafish, a transparent member of the minnow family, are providing insight into human melanoma – a form of skin cancer – that may lead to new or repurposed drug treatments, for skin and other cancers.

Cancer's next magic bullet may be magic shotgun Posted: 15 Jun 2012 11:17 AM PDT A new approach to drug design promises to help identify future drugs to fight cancer and other diseases that will be more effective and have fewer side effects.

New surgery may reverse hand paralysis Posted: 15 Jun 2012 11:16 AM PDT A reconstructive neurosurgeon has pioneered a novel technique to restore hand function in patients with spinal cord injury. In a delicate four-hour procedure, he splices together tiny nerve endings, only one millimeter in width, to help restore hand mobility.

Genetic markers hope for new brain tumor treatments Posted: 15 Jun 2012 08:40 AM PDT Researchers have identified three sets of genetic markers that could potentially pave the way for new diagnostic tools for a deadly type of brain tumor that mainly targets children.

Active ingredient of cannabis has no effect on the progression of multiple sclerosis, study suggests Posted: 15 Jun 2012 07:39 AM PDT The first large non-commercial study to investigate whether the main active constituent of cannabis (tetrahydrocannabinol or THC) is effective in slowing the course of progressive multiple sclerosis shows that there is no evidence to suggest this; Although benefits were noted for those at the lower end of the disability scale.

BPA exposure effects may last for generations Posted: 15 Jun 2012 07:35 AM PDT Exposure to low doses of Bisphenol A (BPA) during gestation had immediate and long-lasting, trans-generational effects on the brain and social behaviors in mice, according to a recent study.

Persistence is learned from fathers, study suggests Posted: 15 Jun 2012 07:35 AM PDT A longitudinal study found that adolescents learn persistence through fathers who follow good parenting practices. As a result, these adolescents saw higher engagement in school and lower rates of delinquency.

Graphic warning labels improve smokers' recall of warning and health risks related to smoking Posted: 15 Jun 2012 07:35 AM PDT In a first of its kind study in the U.S., researchers have shown that the addition of graphic warning labels on cigarette packaging can improve smokers' recall of the warning and health risks associated with smoking.

Vitamin D with calcium shown to reduce mortality in elderly Posted: 15 Jun 2012 07:35 AM PDT A recent study suggests that vitamin D —- when taken with calcium —- can reduce the rate of mortality in seniors, therefore providing a possible means of increasing life expectancy.

Unexpected discovery highlights new role for cell death regulator Posted: 14 Jun 2012 03:27 PM PDT Scientists have already revealed the mechanism by which high alcohol intake can induce pancreatitis and its progression to pancreatic cancer. Now a new study reveals a hitherto unknown interaction between two well known molecules, which has important implications for our understanding of inflammation and cancer in the pancreas as well as other organs.

Training people to inhibit movements can reduce risk-taking Posted: 14 Jun 2012 10:09 AM PDT People can train their brains to become less impulsive, resulting in less risk-taking during gambling. The research could pave the way for new treatments for people with addictions to gambling, drugs or alcohol as well as impulse-control disorders, such as ADHD.

New report estimates nearly 18 million cancer survivors in the US by 2022 Posted: 14 Jun 2012 10:09 AM PDT The number of Americans with a history of cancer will grow to almost 18 million by 2022, according to a first-ever report by the American Cancer Society and the National Cancer Institute.

Scientists define the healthy human microbiome Posted: 13 Jun 2012 03:40 PM PDT Scientists have for first time mapped the normal microbial make-up of humans. Berkeley Lab's role in mapping the human microbiome revolves around big data, both analyzing it and making it available for scientists to use worldwide. The research will help scientists understand how our microbiome keeps us healthy. It'll also shed light on our microbiome's role in many diseases.

Improving high-tech medical scanners Posted: 13 Jun 2012 12:33 PM PDT A powerful color-based imaging technique is making the jump from remote sensing to the operating room. Scientists are working to ensure it performs as well when spotting cancer cells in the body as it does with oil spills in the ocean.

Predicting post-traumatic stress disorder before it happens Posted: 13 Jun 2012 12:33 PM PDT Using brain imaging and function techniques, scientists have developed an interdisciplinary method to identify pre-traumatic subjects. It's a novel approach to diagnosing and treating victims of PTSD -- and they say the findings can be used to monitor people at high risk for this disorder, including soldiers in combat units.

Normal bacterial makeup has huge implications for health Posted: 13 Jun 2012 11:54 AM PDT Scientists have mapped the normal microbial makeup of healthy humans.

More than one way to be healthy: Map of bacterial makeup of humans reveals microbial rare biosphere Posted: 13 Jun 2012 10:32 AM PDT New results confirm concept of "rare biosphere" of microbial life, originally discovered in ocean samples, and with many implications for human health.
