Power-talkers with cell phones glued to their ears may be getting more than conversation. A 50-minute call boosts activity in brain regions near the ear where a phone is located, a brain-scanning study published February 22 in the Journal of the American Medical Association shows.

“This is the first paper that really shows there are changes in the brain,” says bioengineer Henry Lai of the University of Washington in Seattle, who coauthored an editorial published in the same issue of JAMA. Talking on a cell phone pressed to the ear, he says, “is not really safe.”

WASHINGTON: Fifty million "environmental refugees" will flood into the global north by 2020, fleeing food shortages sparked by climate change, experts warned at a major science conference that ended here Monday.

"In 2020, the UN has projected that we will have 50 million environmental refugees," University of California, Los Angeles professor Cristina Tirado said at the annual meeting of the American Association for the Advancement of Science (AAAS).

"When people are not living in sustainable conditions, they migrate," she continued, outlining with the other speakers how climate change is impacting both food security and food safety, or the amount of food available and the healthfulness of that food.
