Remnants of Earth's primordial crust found in Australia

Our planet was born around 4.5 billion years ago. To understand this mind-bendingly long history, we need to study rocks and the minerals they are made of. In a new study, evidence of rocks of a similar age were found in Australia.

AI Designs Radical Magnet Free of Rare-Earth Metals in Just 3 Months

We urgently need to move away from fossil fuels, but electric vehicles and other green technology can put their own pressures on the environment. That pressure could be eased with a new magnet design that was built with AI.
