Sweden says it found the largest deposit in Europe of rare earths — ingredients in a host of technologies from e-vehicles to wind turbines. Mining and processing them is another story.
Geologists rely on tiny crystals of the mineral zircon to understand the timing of key events in Earth's early days, like the rising of continents and the emergence of oceans.
NASA's Apollo missions already sent astronauts to the moon from 1969 to 1972. But scientists say there's still lots of good science to do there. The moon also could be an ideal stepping stone to Mars.
Scientists on five continents are hunting for geological evidence to pinpoint exactly when humans became a major force shaping life on Earth. But settling on the date could unleash a larger debate.

Studying active volcanoes can be dangerous, which is why a group of scientists from around the world came together to simulate volcanic blasts. What they're learning will help them at a real eruption.
A new analysis of what were initially thought to be microbial fossils in Greenland suggests they might instead just be mineral structures created when ancient tectonic forces squeezed stone.
A 16-year-old in southwestern Minnesota drove into an unexpected cleft that had opened up in the earth; he escaped safely by crawling out of the back window of his car.
When scientists got their hands on a collection of the world's biggest gem diamonds, they found something surprising inside — clues about what sits hundreds of miles beneath our feet.
