Celestial AI, a startup developing light-based AI accelerator chips, has raised $56 million in venture funding.

Efforts to mimic the brain in silicon—a field known as neuromorphic computing—have a long pedigree, and have seen significant investments from computing powerhouses like Intel and IBM. So far, most research has focused on replicating the functionality and connectivity of biological neurons and synapses in the hope of replicating the brain’s incredible learning efficiency.

One feature of neurons that has received less attention is the way they’re able to reorganize themselves in response to experience. This powerful capability allows the brain to change both its structure and function as it learns, optimizing its underlying hardware to new challenges on the fly.

Now though, a team led by engineers from Purdue University has demonstrated new circuit components whose functions can be reconfigured with simple electronic pulses. This allows them to seamlessly switch between acting as resistors, memory capacitors, artificial neurons, and artificial synapses. The breakthrough opens the door to creating dynamic neural networks in hardware that can rewire themselves as they learn—just like the brain.

CHICAGO, Feb 4 (Reuters) — A study in monkeys pitting the current Moderna Inc (MRNA.O) COVID-19 booster against an Omicron-specific booster showed no significant differences in protection, suggesting an Omicron-specific booster may not be needed, U.S. government researchers reported on Friday.

The study involved monkeys vaccinated with two doses of Moderna’s vaccine who were dosed nine months later with either the conventional Moderna booster or one specifically targeting the Omicron variant.

A Chinese satellite was spotted apparently clearing up space junk. But US officials are concerned the technology could be used against non-junk satellites.

Last month, a private satellite tracking company spotted a Chinese spacecraft apparently grabbing and throwing a dead satellite away into a “graveyard” orbit.

A Falcon 9 rocket is on a fatal trip to the Moon — and an Earth-based observatory just caught a sneak peek.

A Falcon 9 rocket is expected to crash land on the Moon in early March. An Earth-based observatory caught it on its way to the Moon.
