In the decade-long fight to control CRISPR, the super-tool for modifying DNA, it's been common for lawyers to try to overturn patents held by competitors. But now, in a surprise twist, the team that earned the Nobel Prize in chemistry for developing CRISPR is asking to cancel two of their own seminal patents, MIT Technology Review has learned. The request to withdraw the pair of European patents, by lawyers for Emmanuelle Charpentier and Jennifer Doudna, comes after a damaging August opinion from a European technical appeals board, which ruled that the duo's earliest patent filing didn't explain CRISPR well enough for other scientists to use it and doesn't count as a proper invention. The decision could have major ramifications regarding who gets to collect the lucrative licensing fees on using the technology.Read the full story. What's new: The Allen Institute for Artificial Intelligence (Ai2), a research nonprofit, is releasing a family of open-source multimodal language models, called Molmo, that it says perform as well as top proprietary models from OpenAI, Google, and Anthropic.

The significance: These emissions will add up quickly. The generative-AI boom has led big tech companies to integrate powerful AI models into many different products, from email to word processing. They are now used millions, if not billions, of times every single day. The bigger picture: The study shows that while training massive AI models is incredibly energy intensive, it's only one part of the puzzle. Most of their carbon footprint comes from their actual use.
