By prodding a tiny brain region linked to consciousness, scientists caused anaesthetised monkeys to suddenly become awake and alert. This fascinating result is providing new clues about the brain and how it produces conscious awareness—insights that could potentially lead to therapies for patients trapped in a coma.
Scientists in China created piglets whose organs contained some monkey cells. The piglets all died within a week, illustrating the challenges ahead as researchers work toward the goal of growing human organs inside other animals.
The partially U.S. government-funded National Academy of Sciences removed a webpage with a video describing gene editing in ways that conflict with the organisation’s own ethical guidelines.
