Utah launches AI program for acne prescriptions
Nolla Health launched a Utah AI program for mild-to-moderate acne, using facial scans and health information to recommend approved medications. During the year-long program, doctors will approve the first 100 prescriptions, retrospectively review the next 400 each week, and then assess at least 10% per month.
A Utah healthcare startup launched an acne-treatment program in which AI recommends prescriptions while physician oversight is gradually reduced.
OpenSSH 10.6 was released with security fixes and new features. The version disables compression to mitigate a side-channel attack that could extract secrets by exploiting the shared LZ77 dictionary in SSH channels. The team says it will release versions more frequently following reports assisted by AI.
OpenSSH 10.6 has been released with security fixes and new features, including measures to reduce a compression-related side-channel risk.

Polars 2.0 makes streaming its default engine
Polars 2.0 uses the streaming engine by default when `collect` is called on a LazyFrame; supported operations can spill to disk at around 80% of RAM usage. The company reports the fastest result on most TPC-H and TPC-DS measurements, but some operations do not preserve row order, and small queries may slow down with multiple cores.

AI agents identify two magnetic semiconductor candidates for spintronics
Simulations predict magnetic order above room temperature for YBaMnFeO₅, though producing the useful atomic arrangement may be difficult. A KV[Cr(CN)₆] sample synthesized in 1999 retained magnetic order up to 376 K; however, its band gap and spin splitting have not yet been measured.
Agents’ quantum-mechanics simulations identified two Luttinger-compensated semiconductors as spintronics candidates: one newly designed, the other made in 1999.
