MIT robot builds working laser cavity in 50 maneuvers under 30 minutes, self-corrects after disruption September 19, 2026 at 12:30AM

Massachusetts Institute of Technology researchers developed a robotic optics laboratory. This system autonomously assembles and aligns laser cavities with precision. The robot can also correct experimental setups after they are disturbed. This technology could accelerate testing for various optical devices and materials. Future applications envision remote interaction with these automated research environments.

California buried a gas pipeline and removed its final barrier; salmon returned after 70 years September 18, 2026 at 11:30PM

A decades-long barrier blocking fish migration in Alameda Creek was removed in 2025. This action reopened over twenty miles of upstream habitat for migratory fish. Chinook salmon were documented in the newly accessible area shortly after the construction. This marked the first access to this watershed section since the 1950s. The project is part of a larger, nearly thirty-year restoration effort.
