New clues about how cancer cells grow

Scientists in Switzerland are uncovering new clues about how cancer cells grow - and how they can be killed - by studying stem cells, 'blank' cells that have the potential to develop into fully mature or 'differentiated' cells and other scientists in UK have made a breakthrough in understanding the cause of the most common form of childhood cancer, acute lymphoblastic leukaemia (ALL).

People with manic depression have a distinct chemical signature in their brains

People with manic depression have a distinct chemical signature in their brains, according to a new study. The research, published in the journal Molecular Psychiatry, may also indicate how the mood stabilisers used to treat the disorder counteract the changes in the brain that it appears to cause.
