U.S. Treasury Secretary Bessent said the Treasury is communicating with every country to convey its expectations.

Researchers at the Transient Optics Laboratory, Xi'an Institute of Optics and Precision Mechanics (Chinese Academy of Sciences), led by Liu Hongjun, published in Laser & Photonics Reviews a demonstration extending nonlocal metasurface control to continuous‑wave nonlinear mid‑infrared frequency upconversion imaging. The technique enables compact, low‑cost, high‑sensitivity mid‑IR detection with on‑chip integration potential; cited application areas include gas detection, environmental monitoring, biomedical imaging and integrated photonic sensing.

Japan's finance minister Katayama said he has received various views on a retail-focused JGB issuance scheme.
