Workers sent from the country to Chinese factories describe enduring beatings and sexual abuse, having their wages taken by the state, and being told that if they try to escape they will be “killed without a trace.”
Disturbances on the sun may have the potential to devastate our power grid and communication systems. When the next big storm arrives, will we be prepared for it?
COVER STORIES
An ancient solar storm helps pinpoint when Vikings lived in the Americas, and using magnets to deftly move non-magnetic metals.

00:53 Pinpointing Viking presence in North America
It’s well-understood that Vikings went to North America around a thousand years ago. However, working out a precise date has proven difficult. Now, thanks to an ancient solar storm, researchers have been able to identify an individual year when Vikings were definitely living on the continent.
