Researchers build brain-like memory device for AI sensors that may improve energy efficiency — phototransistor device combines light sensing, memory, and processing to cut data movement

Oregon State University researchers have developed a brain-inspired phototransistor that combines light sensing, memory, and signal processing in one device. The hardware can electronically control how long optical memories persist or fade, potentially improving energy efficiency in future AI vis...

U.S. gov't asks court to dismiss NAACP lawsuit against Elon Musk's xAI over use of unpermitted gas turbines — DOJ says Grok model running at Colossus 2 ‘supports mission-critical operations’

The US government is seeking dismissal of a lawsuit from the NAACP, arguing that the Colossus 2 data center is crucial for national security. The data center runs the Grok Gov AI model, and the government claims a shutdown "directly threatens ongoing national security interests."
