Omega-3 fatty acids and vitamin D may control brain serotonin

Although essential marine omega-3 fatty acids and vitamin D have been shown to improve cognitive function and behavior in the context of certain brain disorders, the underlying mechanism has been unclear. In a new paper published in FASEB Journal by Rhonda Patrick, PhD and Bruce Ames, PhD of Children's Hospital Oakland Research Institute (CHORI), serotonin is explained as the possible missing link tying together why vitamin D and marine omega-3 fatty acids might ameliorate the symptoms associated with a broad array of brain disorders.

Graphene shows potential as novel anti-cancer therapeutic strategy

University of Manchester scientists have used graphene to target and neutralise cancer stem cells while not harming other cells. This new development opens up the possibility of preventing or treating a broad range of cancers, using a non-toxic material. Writing in the journal Oncotarget, the team of researchers led by Professor Michael Lisanti and Dr Aravind Vijayaraghavan has shown that graphene oxide, a modified form of graphene, acts as an anti-cancer agent that selectively targets cancer stem cells (CSCs).

Safety and life-saving efficacy of statins have been exaggerated

Hailed as miracle drugs when they hit the market two decades ago, statins, the cholesterol-lowering drugs prescribed to prevent heart attacks, are not as effective nor as safe as we have been led to believe, say Dr. David M. Diamond, a professor of psychology, molecular pharmacology and physiology at the University of South Florida, and Dr. Uffe Ravnskov, an independent health researcher and an expert in cholesterol and cardiovascular disease.

New nanogel for drug delivery

Scientists are interested in using gels to deliver drugs because they can be molded into specific shapes and designed to release their payload over a specified time period. However, current versions aren't always practical because must be implanted surgically. To help overcome that obstacle, MIT chemical engineers have designed a new type of self-healing hydrogel that could be injected through a syringe.

New test to predict the effectiveness of cancer vaccines

Cancer vaccines are designed to turn the body's own immune system specifically against tumor cells. Particularly promising are vaccines that are directed against so-called neoantigens: These are proteins that have undergone a genetic mutation in tumor cells and, therefore, differ from their counterparts in healthy cells.
