The tiny worm Caenorhabditis elegans has a brain just about the width of a human hair. Yet this animal’s itty-bitty organ coordinates and computes complex movements as the worm forages for food. “When ...

Putting a computer inside someone’s brain used to feel like the edge of science fiction. Today, it’s a reality. Academic and commercial groups are testing “brain-computer interface” devices to enable ...

The human brain is more powerful and energy-efficient than any computer. Scientists are imitating the way it works to produce better computer chips and help deal with the growing amounts of data ...

Researchers are no longer just simulating brains in silicon, they are wiring living human neurons into machines and asking them to compute. Tiny clusters of brain cells, grown from stem cells and ...

It's a very nascent area; GPT-5 will certainly not be trained using human brain cells. But these natural computers are so incredibly efficient – up to a billion times more energy-efficient than ...
