- A new integrated photonic tensor-core unit is proposed that uses wavelength-division multiplexing, 2-ps optoelectronic delays, and phase-change-material memory to reach 2 POPS throughput—yielding 10–100× higher energy efficiency than electronic tensor cores for 4-bit precision (AIP Advances paper, DOI 10.1063/5.0001942).

- UC Davis researchers unveiled “Cosmo,” a CRISPR-edited bull calf carrying an extra SRY gene on chromosome 17; offspring that inherit the edit will develop as phenotypic males regardless of sex-chromosome complement, promising ~75 % male calves for beef production efficiency.

- The U.S. Office of the Comptroller of the Currency followed Wyoming’s lead and will allow national banks to custody digital assets, a regulatory shift expected to accelerate mainstream crypto adoption and help the U.S. regain competitiveness in digital-asset infrastructure.

- diyhpluswiki added a transcript of Christopher Allen’s 2018 talk on “smart signatures,” covering advanced cryptographic signature schemes and their role in blockchain protocol security engineering.

- Channel members highlighted the conceptual distinction between genetic sex (presence of Y chromosome) and phenotypic sex (expression of SRY gene), underscoring the nuance in Cosmo’s breeding strategy.
