‘Watch them die’: Bird flu is ravaging a Utah mink farm, killing 80% of the herd. State agriculture officials have no clear plan.
It’s the first documented outbreak of bird flu in captive mink in the U.S., and an advocacy group is raising concerns about Utah’s response.

Ignore for a moment the question about whether Anthropic trains on user sessions. I am I right in reading this as saying that Anthropic's "never-before-discovered" reverse transcriptase was *patented* three years ago?
Dr. Mestre first encountered the enzymes in jumbo phages in 2022 while searching for new reverse transcriptases. He worked briefly as a consultant for ReNegade Therapeutics, which filed a patent in 2023 on a number of reverse transcriptases, including the ones Dr. Mestre found. He is listed as a co-inventor on the patent filing.
