For the first time, Australian researchers have been able to see where helium atoms are trapped within individual mineral grains, leading to information that can help work out the geological history of the Earth's crust - and help with monitoring natural hazards like earthquakes and volcanic eruptions.

Over the weekend, the Chilean government ended a state of emergency enacted last month in response to the worst bushfire season in the nation's history. The fires, which now appear to be dying down, have torched more than 900,000 acres — roughly four times the area of New York City — since January 15.
"Lava viewing area" sounds like a feature of your favourite Super Mario game, but it's also a real thing in Hawaii, where you can watch the Kilauea shield volcano spew its fiery guts right into the ocean from a cliff. Or at least, you were able to do that, until the cliff in question crumbled into the ocean on New Years' Eve.
More than 100 small earthquakes have struck the Southern California-Mexico border since Saturday. But while "quake swarm" sounds like the term Morgan Freeman uses in the disaster movie right before Los Angeles cracks off into the ocean, real scientists say this particular event is nothing to worry about.
Seventy per cent of Earth's surface is covered by water, meaning if we were unfortunate enough to be struck by an enormous asteroid, it'd probably make a big splash. A team of data scientists at Los Alamos National Laboratory recently decided to model what would happen if an asteroid struck the sea. Despite the apocalyptic subject matter, the results are quite beautiful.
Over the summer in Tibet, two enormous avalanches struck the Aru Glacier back-to-back. Now, after several months of careful study, scientists think they have identified the cause of the first ice slide, which claimed the lives of nine nomadic herders. You'll be shocked to hear it has to do with climate change.
