New cancer drug to begin trials in multiple myeloma patients

Scientists at Imperial College London have developed a new cancer drug which they plan to trial in multiple myeloma patients by the end of next year. In a paper published in the journal Cancer Cell, the researchers report how the drug, known as DTP3, kills myeloma cells in laboratory tests in human cells and mice, without causing any toxic side effects, which is the main problem with most other cancer drugs.

Bio-inspired 'nano-cocoons' offer targeted drug delivery against cancer cells

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.

Chemical derived from broccoli sprouts shows promise in treating autism

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.

Mechanism that repairs brain after stroke discovered

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.
