Giant clouds of lead glimpsed on distant dwarf stars
A lead balloon may be a metaphor for something unpopular, but real life clouds of lead glimpsed in the atmosphere of two stars are having the opposite effect. The giant clouds - thought to be 100 kilometres thick - are helping to boost a theory of stellar evolution.
Biggest extinction in history caused by climate-changing meteor
It's well known that the dinosaurs were wiped out 66 million years ago when a meteor hit what is now southern Mexico but evidence is accumulating that the biggest extinction of all, 252.3m years ago, at the end of the Permian period, was also triggered by an impact that changed the climate.
When Ambulances Can’t Get There in Time, the Nimble Ambucycle Saves Lives
Congestion kills. That's not hyperbole, it's a fact. In dozens of cities across the world, heavy traffic, construction, and poorly maintained roads keep first responders from getting to patients in time. That's where the Ambucycle comes in.
