Biomedical engineering researchers have developed a drug delivery system consisting of nanoscale "cocoons" made of DNA that target cancer cells and trick the cells into absorbing the cocoon before unleashing anticancer drugs. The work was done by researchers at North Carolina State University and the University of North Carolina at Chapel Hill.

Results of a small clinical trial suggest that a chemical derived from broccoli sprouts - and best known for claims that it can help prevent certain cancers - may ease classic behavioral symptoms in those with autism spectrum disorders (ASDs). The study, a joint effort by scientists at MassGeneral Hospital for Children and the Johns Hopkins University School of Medicine, involved 40 teenage boys and young men, ages 13 to 27, with moderate to severe autism.

A previously unknown mechanism through which the brain produces new nerve cells after a stroke has been discovered at Lund University and Karolinska Institute in Sweden. The findings have been published in the journal Science. A stroke is caused by a blood clot blocking a blood vessel in the brain, which leads to an interruption of blood flow and therefore a shortage of oxygen.

New research shows probiotic yogurt can reduce the uptake of certain heavy metals and environmental toxins by up to 78% in pregnant women. Led by Scientists at Lawson Health Research Institute's Canadian Centre for Human Microbiome and Probiotic Research, this study provides the first clinical evidence that a probiotic yogurt can be used to reduce the deadly health risks associated with mercury and arsenic.

University of Utah biochemists have reported a new drug discovery tool against the Ebola virus. According to a study published in this week's online edition of Protein Science, they have produced a molecule, known as a peptide mimic, that displays a functionally critical region of the virus that is universally conserved in all known species of Ebola.

Type 2 diabetes affects an estimated 28 million Americans according to the American Diabetes Association, but medications now available only treat symptoms, not the root cause of the disease. New research from Rutgers shows promising evidence that a modified form of a different drug, niclosamide - now used to eliminate intestinal parasites - may hold the key to battling the disease at its source.

The Nobel Assembly at Karolinska Institutet has today decided to award The 2014 Nobel Prize in Physiology or Medicine with one half to John O'Keefe and the other half jointly to May-Britt Moser and Edvard I. Moser for their discoveries of cells that constitute a positioning system in the brain.
