That push involves building more AI-accelerating chips, more data centers, and even new nuclear plants to power those data centers, in some cases. Along those lines, Microsoft, BlackRock, Global Infrastructure Partners (GIP), and MGX announced a massive new AI investment partnership on Tuesday called the Global AI Infrastructure Investment Partnership (GAIIP).

X's revival was enabled by the company switching to a different network provider, namely Cloudflare, but Cloudflare reportedly made changes that allow ISPs to resume their blocking of X. "When X was shut down in Brazil, our infrastructure to provide service to Latin America was no longer accessible to our team," X's Global Government Affairs account said last night.

One way to bridge that gap is building biohybrid robots that merge synthetic machinery with biological components like animal muscles, bacteria, or plants. But living muscles are very hard to keep alive in a machine, bacteria have a very short lifespan, and plants tend to react to things a bit slowly, like Ents in The Lord of the Rings.

(credit: BMW) Battery recycling company Redwood Materials gained a new automaker partner today. It has agreed to a deal with BMW of North America to recycle lithium-ion battery packs from BMW's electrified vehicles and will eventually use recycled material from Redwood in battery packs for BMWs built in North America as the automaker works toward a closed-loop supply chain. "Our partnership with BMW of North America ensures responsible end-of-life battery management that will improve the environmental footprint of lithium-ion batteries, help decrease cost and, in turn, increase access and adoption of electric vehicles," said Cal Lankton, chief commercial officer at Redwood Materials. Redwood was founded by former Tesla CTO JB Straubel in 2017, and in recent years, the startup has signed partnerships with Ford, Volvo, Volkswagen, and more recently General Motors.
