  • Seeing the action: Novel device images minute forces, actions involved in cell membrane hemifusion
    Researchers have developed a novel device to image the minute forces and actions involved in cell membrane hemifusion. To capture real time data on the behavior of cell membranes during hemifusion, the researchers pressed together two supported lipid bilayers on the opposing surfaces of the SFA. These bilayers consisted of lipid domains -- collections of lipids that in non-fusion circumstances are organized in more or less regularly occurring or mixed arrangements within the cell membrane.

  • 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.
