New clues to how the brain and body communicate to regulate weight Posted: 26 Oct 2012 12:37 PM PDT Researchers describe new findings that help explain the neurocircuitry underlying the fat-burning properties of brown fat.

Solving stem cell mysteries Posted: 26 Oct 2012 12:36 PM PDT The ability of embryonic stem cells to differentiate into different types of cells with different functions is regulated and maintained by a complex series of chemical interactions, which are not well understood. Learning more about this process could prove useful for stem cell-based therapies down the road. New research zeroes in on the process by which stem cells maintain their proper undifferentiated state.

Drug shows promise in animal model of Alzheimer's and Parkinson's with dementia Posted: 26 Oct 2012 11:33 AM PDT New research demonstrates the role of the investigational compound IRX4204 in alleviating cognitive decline in animal models of Alzheimer's disease.

Progress in ultrasound-guided surgery may improve breast cancer treatment Posted: 26 Oct 2012 11:32 AM PDT Scientists are developing an alternate means of precisely tagging breast cancer tumors for removal or targeted destruction.

New materials may help prevent infections by blocking initial bacterial attachment Posted: 26 Oct 2012 11:32 AM PDT Recently a team of British researchers has discovered a new class of materials that resists bacterial attachment.

Immune system fighters speak in patterns of proteins, prefer squishy partners Posted: 26 Oct 2012 11:32 AM PDT Researchers have discovered two new conditions for immune system communication that may help scientists one day harness the power of T-cells to fight diseases such as cancer.

Drug used to treat glaucoma actually grows human hair Posted: 26 Oct 2012 09:51 AM PDT If you're balding and want your hair to grow back, then here is some good news. A new research shows how the FDA-approved glaucoma drug, bimatoprost, causes human hair to regrow. It's been commercially available as a way to lengthen eyelashes, but these data are the first to show that it can actually grow human hair from the scalp.

Bean used in Chinese food could protect against sepsis Posted: 26 Oct 2012 09:51 AM PDT Researchers have discovered that a bean commonly used in Chinese cuisine protects against the life-threatening condition sepsis.

Autism early intervention found to normalize brain activity in children as young as 18 months Posted: 26 Oct 2012 09:50 AM PDT An intensive early intervention therapy that is effective for improving cognition and language skills among very young children with autism also normalizes their brain activity, decreases their autism symptoms and improves their social skills, a nationwide study has found. The researchers said the study is the first to demonstrate that an autism early intervention program can normalize brain activity.

Magnetic brain stimulation treats depression independent of sleep effect Posted: 26 Oct 2012 09:50 AM PDT While powerful magnetic stimulation of the frontal lobe of the brain can alleviate symptoms of depression, those receiving the treatment did not report effects on sleep or arousal commonly seen with antidepressant medications, researchers say.

New options for ease and accuracy in extraction of rare cells or separating blood Posted: 26 Oct 2012 09:50 AM PDT Using something called "inertial microfluidics," researchers are able to continuously and selectively collect rare cells, such as circulating tumor cells, based on their size vs. other biomarkers. This could reduce analysis time and increase selectivity while reducing reliance on antibody-based testing in clinical tests.

Watching the cogwheels of the biological clock in living cells Posted: 26 Oct 2012 09:50 AM PDT Most physiological functions in mammals are controlled by a daily internal time-keeping system, termed the circadian clock. The transcription of many genes producing detoxifying enzymes is regulated by DBP, a protein that is itself expressed in a highly rhythmic fashion. Scientists have now deciphered the molecular basis of how the circadian clock controls the rhythmic production of DBP protein in individual living cells.

Dietary supplements can cause liver injury, says hepatologist Posted: 26 Oct 2012 09:48 AM PDT Niacin, comfrey, Kava and even green tea in high doses can cause liver injury, according to an expert.

Sickle cell anemia: Maps and newborn estimates released Posted: 26 Oct 2012 08:01 AM PDT In 2010 around 300,000 babies were born with sickle cell anemia, a serious blood disorder which can be fatal if untreated, and 5.5 million newborns inherited the sickle cell gene, a new study suggests.

Elevated formaldehyde levels found in day care centers Posted: 26 Oct 2012 07:09 AM PDT A study of 40 child-care facilities in California found that most had levels of formaldehyde and a few other contaminants that exceeded exposure guidelines. The study is the first to provide a detailed analysis of environmental contaminants and exposures for children in day care centers.

Measuring molecules with the naked eye: Chemists' innovation may be a better model for disease diagnostic kits Posted: 26 Oct 2012 07:09 AM PDT A new "lab on a chip" reveals the presence of ultra-low concentrations of a target molecule to the naked eye. This model for diagnostic testing could mean point-of-care results displayed visually for diseases that involve very subtle shifts in the bloodstream.

Diabetes raises levels of proteins linked to Alzheimer's features, study finds Posted: 26 Oct 2012 07:09 AM PDT Growing evidence suggests that there may be a link between diabetes and Alzheimer's disease, but the physiological mechanisms by which diabetes impacts brain function and cognition are not fully understood. In a new study published in Aging Cell, researchers at the Salk Institute for Biological Studies show, for the first time, that diabetes enhances the development of aging features that may underlie early pathological events in Alzheimer's.

New tools developed to better treat ADHD patients in early stages Posted: 26 Oct 2012 07:08 AM PDT Researchers have developed a method to get better input from parents and teachers of children who are being diagnosed with ADHD for the first time -- allowing for more effective treatment upon the first consultation. Researchers also showed how a tool can help clinicians better diagnose and treat children who have both ADHD and oppositional defiance disorder.

High-risk carotid artery plaque formation is increased in older COPD patients Posted: 26 Oct 2012 05:46 AM PDT Older patients with chronic obstructive pulmonary disease are at increased risk for carotid artery plaque formation and for the presence of vulnerable plaques with a lipid core, according to a new study.

Smoking takes 10 years off life expectancy in Japan, not 4 as previously thought, experts warn Posted: 25 Oct 2012 04:36 PM PDT Smoking reduces life expectancy by ten years in Japan, but much of the risk can be avoided by giving up smoking, a new paper shows.
