China has eclipsed its own - and the US - record, building a monster underground hypergravity centrifuge that can model scenarios with 1,900 times the real-world gravitational force of Earth, bending space and time with unprecedented power.

In northwestern Greenland, researchers working on the GreenDrill project have cored through a 500-meter-thick ice dome. They found something startling: the dome completely disappeared 7,000 years ago. And it might do it again.
