Drug shrinks brain tumors in children with tuberous sclerosis complex

A drug originally developed to prevent organ rejection has been shown to dramatically reduce a particular kind of brain tumor in patients with tuberous sclerosis complex (TSC). The study found that 35% of patients experienced at least a 50% reduction in tumor volume after treatment with everolimus.

Warming temperatures will change Greenland's face

Scientists predict that Greenland's ice sheet will lose more ice and snow to melting than it will accumulate over the next century due to warming temperatures. Basins on the southwest and north coasts will suffer the greatest losses, with temperatures only needing to increase by 0.6-2.16C for net loss.
