A vast, ancient crater in the western United States may be home to one of the most significant mineral discoveries of the century. Published in the journal Science Advances, researchers have identified a geological formation beneath this site that could dramatically reshape the global landscape for clean energy technology. A Supervolcano’s Legacy Becomes a Resource Powerhouse The McDermitt Caldera, measuring 45 by 35 kilometers, was formed 16.4 million years ago following a catastrophic volcanic eruption. Over time, a lake developed inside the caldera, collecting thick layers of volcanic ash and mineral-rich sediments. These conditions gave rise to lithium-bearing clay minerals,...

Monkeys in modern-day Thai forests create stone artifacts uncannily similar to those crafted by early humans — challenging the established narrative of human cultural evolution. A new study published on Friday in Science Advances suggests the possibility that a critical hallmark of human tool use happened by accident — potentially blurring the line between tool use by early humans and our primate relatives. - snip - In an abandoned oil palm plantation on a national park site, the monkeys would create nut-cracking ‘stations’ beneath the feral trees. There they break open the palm fruit’s oil-rich pit between hand-wielded hammer rocks...

Researchers at Columbia Engineering report that they have built what they say is the world's smallest single-chip system, consuming a total volume of less than 0.1 mm3. The system is as small as a dust mite and visible only under a microscope. In order to achieve this, the team used ultrasound to both power and communicate with the device wirelessly. The study was published online May 7 in Science Advances. “We wanted to see how far we could push the limits on how small a functioning chip we could make,” said the study’s leader Ken Shepard, Lau Family professor of...
