AI company Anthropic has filed a lawsuit against the U.S. Defense Department seeking to overturn a “supply chain risk” designation that effectively blocks the firm from Pentagon contracts.

Physicists induced superconductivity in gallium‑doped germanium at 3.5 K, a CMOS‑ready step toward hybrid quantum chips. Foundry‑compatible Ge can unify superconducting and classical logic on one wafer—promising advances in quantum circuits, sensors, and ultra‑low‑power AI compute.
