- 1Chinese Stocks Fall to One-Year Low on Chip Slump▼Chinese Stocks Hit One-Year Low as Chip, Optical Firms Slide
Chinese equities dropped to their lowest level in a year, with semiconductor and optical technology companies leading the decline. The slide reflects mounting pressure on China's tech sector, particularly firms tied to chipmaking and optical components, which have been hit by weak demand and ongoing US export restrictions. Investors are watching closely for signs of further deterioration or policy support from Beijing to stabilise the market.
- 2Ultrafast Lasers Track Material Light Response at Electron Level▼Optica Ultrafast Lasers Reveal Material Light Response Down To The Electron
Researchers working under Optica's ultrafast laser research report that new laser techniques can reveal how materials respond to light down to the level of individual electrons. The advance gives scientists a more direct view of the electron dynamics that underpin light-matter interactions, with potential relevance for photonics, electronics and materials science, though detailed findings remain limited in available coverage.

Researchers report that hyperbolic wave attractors, structures that trap and concentrate light waves, could be used to build next-generation optical chips. By confining light more efficiently, the approach may improve photonic circuits used in computing and communications. Details of the research and its practical applications remain limited in the available reporting.
