Harvard scientists have manipulated stem cells already present in the brains of mice to induce the birth of new neurons, an advance once considered impossible by most scientists.
They induced the birth of new cells by killing nearby neurons in mice, which set off a cascade of events that led to stem cells, producing new neurons in the cerebral cortex. If scientists can turn this into a therapy for humans, it would mean that patients could literally heal themselves with stem cells already present in their brains.

Australian commenters are very very strongly advised to publish anonymously. Sydney alone has more defamation actions than the entire USA and UK. Nearly double that of the UK in fact.
