A chip placed under the skin for more precise medicine
It's only a centimeter long, it's placed under your skin, it's powered by a patch on the surface of your skin and it communicates with your mobile phone. The new biosensor chip is capable of simultaneously monitoring the concentration of a number of molecules, such as glucose and cholesterol, and certain drugs.

Cocaine addiction, craving and relapse
One of the major challenges of cocaine addiction is the high rate of relapse after periods of withdrawal and abstinence. But new research reveals that changes in our DNA during drug withdrawal may offer promising ways of developing more effective treatments for addiction. Withdrawal from drug use results in reprogramming of the genes in the brain that lead to addictive personality, say researchers.

Study links better 'good cholesterol' function with lower risk of later heart disease
HDL, the 'good cholesterol' helps remove fat from artery walls, reversing the process that leads to heart disease. Yet recent drug trials and genetic studies suggest that pushing HDL levels higher doesn't reduce the risk of heart disease. Now, an epidemiological study shows that a person's HDL function -- the efficiency of HDL molecules at removing cholesterol -- may be a better measure of coronary heart disease risk and target for heart-protecting drugs.

Investigational immunotherapy treatment shows durable response in patients with metastatic melanoma
Advanced-stage melanoma patients have significant improvement in durable response rate when treated with a genetically-modified form of a herpes virus, whose native form causes the common cold sore, new research shows.

Changing diagnosis codes will challenge emergency medicine
Emergency medicine faces special challenges during this fall's changeover in how medical diagnoses are coded. Nearly a quarter of all ER clinical encounters could pose difficulties, authors of a new report state.

Future vaccine may help lower blood pressure long-term
A DNA vaccine helped lower blood pressure for up to six months, reduced tissue damage to the heart and blood vessels associated with hypertension in rats, investigators report. If future research shows the vaccine is a viable treatment option in humans, it could improve high blood pressure levels.

Moderate drinking in later years may damage heart
Moderate to heavy alcohol intake later in life may be associated with subtle changes in the structure and efficiency of the heart. Women may be particularly vulnerable to negative cardiac effects of alcohol at moderate to higher levels of consumption.

Study identifies possible role for carbon monoxide in treating hemorrhagic stroke
Carbon monoxide is typically associated with brain injury and neurological symptoms. But a new study suggests that when administered in small, carefully controlled amounts, CO may actually protect the brain from damage following hemorrhagic stroke.

Breakthrough measures Parkinson's progression in brain
A biomarker that shows the progression of Parkinson's disease in the brain has been identified by researchers, opening the door to better diagnosis and treatment of the degenerative disease.

On-demand X-rays at synchrotron light sources
Researchers have developed an 'X-rays on demand' technique in which ALS users can have access to the X-ray beams they want without affecting beams for other users.
