cancer cure: Scientists in Germany are considering developing a new drug for neuroblastoma, a tumour of the nervous system in children.

They studied geometric characteristics using head scans of 3,000 patients. "The next step will be to find out how the differences translate into head impact response of male and female, and then we can design the countermeasure for head protection," says a researcher.
