Canadian scientists have managed to use tiny gas-filled bubbles to get chemotherapy drugs past the brain's protective layer. The technique is being used in six humans who will undergo a trial at Sunnybrook Health Sciences Centre. It is hoped such techniques could be used to treat other diseases like Alzheimer's and Parkinson's. The work comes after a decade of research in many different animal models.

A new vaccine has managed to significantly lower cholesterol levels in mice and macaque monkeys. The vaccine targets the PCSK9 protein, which make it harder for cholesterol to be flushed out of the body. People without this protein have reduced risk of heart disease.
