Deep Dives — In-Depth Analysis

NASA's Nancy Grace Roman Space Telescope has seen starlight for the first time, tested a 300-megapixel camera and may now have fuel for at least 22 years of science.

Regulators confine stem cell therapy for autism to approved trials, psychedelic programs remain unproven, and AI reaches cancer clinics as a check on clinician oversight.

Europe's FTSE 100 rose 0.9% and most Asian benchmarks gained as investors welcomed US-China optimism and an 11-day low in oil, even as France's debt strain deepens.

AI-linked stocks fell across Asia, Europe and the US after OpenAI, Anthropic and Google DeepMind leaders endorsed slowing frontier AI development — a selloff that hit memory chipmakers hardest.

Anthropic confirmed real attacks, lawmakers demanded oversight, and lab leaders asked for a slower race — while the AI buildout kept accelerating.

The FDA's August 2026 cancer approvals centered on Rasonque, a pancreatic cancer pill that nearly doubled median survival. Access, and a Bayer lung cancer expansion, are the next chapters.

A gamma-ray burst led James Webb to the most distant supernova ever seen, a star that died at cosmic dawn. A second burst's photon survived a trip physics said should have destroyed it.
