Anthropic has launched Claude Science, a new AI product that supports scientific research, particularly in computational biology and drug development. This move signals the company’s focus on AI for science and will be used in its own research on rare diseases. The US has also lifted restrictions on Anthropic’s Mythos and Fable models. Meanwhile, California’s carbon offsetting program is under scrutiny for its effectiveness in reducing pollution. Why it matters: these developments highlight the growing role of AI in scientific research and the need for effective climate policies.
