Of 16 gray whales spotted in San Francisco Bay this year, seven have died — several from ship strikes. Climate change is shrinking their Arctic food supply, driving them into the bay on their 12,000-mile Mexico-to-Alaska migration. A coalition of scientists and officials installed a thermal camera on a bay island that detects whale exhalations, screens alerts with AI, and notifies the U.S. Coast Guard in real time.

Des caméras thermiques signalent aux navires la présence de baleines grises à San Francisco

NPR

Sur 16 baleines grises aperçues cette année dans la baie de San Francisco, sept sont mortes — plusieurs heurtées par des navires. Le changement climatique réduit leurs ressources alimentaires en Arctique et les détourne vers la baie lors de leur migration de 20 000 km entre le Mexique et l’Alaska. Une coalition de scientifiques a installé une caméra thermique qui détecte les souffles, filtre les alertes par IA et prévient les garde-côtes en temps réel.

A new type of smart glasses displays real-time captions of spoken conversation directly in the lens as a small green overlay, using directional microphones and AI noise filtering — and no camera. The glasses run two days per charge, support live translation, and fit prescription lenses, making them a discreet daily option for people with hearing difficulties.

A Cornell University political scientist has statistically debunked two decades of influential U.S. research claiming politicians ignore ordinary voters. The flawed studies used selective data and triggered Simpson's paradox. The real gap in political influence, the new analysis finds, lies between the general public and the ultra-wealthy — not between middle- and upper-income groups.

We've told you about the satellite tagging study of 70 whale sharks in Indonesia that revealed previously unknown migration routes, feeding grounds, and a nursery — the data are now being used to establish the country's first whale shark-specific marine protected area in Saleh Bay, Sumbawa, as it's a permanent home, not a seasonal stop.
