Ministers from 55 countries attended talks in Washington aimed at reducing their reliance on China, which dominates the production and processing of the elements. Meanwhile, Japan hopes to revolutionize its own mineral supplies, becoming the first to retrieve deep-sea mud containing rare earth elements.

Musk vows to put data centers in space and run them on solar power but experts have their doubts

An agentic AI tool for battery researchers harnesses data from previous battery designs to predict the cycle life of new battery concepts. With information from just 50 cycles, the tool—developed at University of Michigan Engineering—can predict how many charge-discharge cycles the battery can undergo before its capacity drops below 90% of its design capacity.

It's often seen as a taboo subject. But a new study is finally lifting the lid on sexual fantasies - and what they might say about you.
