Cancer-like metabolism makes brain grow

The size of the human brain increased profoundly during evolution. A certain gene that is only found in humans triggers brain stem cells to form a larger pool of stem cells. As a consequence, more neurons can arise, which ...

Chemical probe to dissect role of potential cancer-causing proteins

Scientists have created a highly specific and well-characterised chemical probe which can switch off two important proteins implicated in cancer—shedding new light on the role these proteins play in driving cancer cell ...
