Today’s science news spans epic animal movement, new conservation technology, and the hazards of a restless planet. Researchers have documented humpback whales making the longest confirmed journeys ever recorded between verified sightings, with individuals traveling roughly 15,000 kilometers between Brazil and eastern Australia — a finding that reshapes understanding of how freely these giants cross ocean basins. At the same time, San Francisco Bay has launched an AI-powered whale detection network designed to spot blows and heat signatures in real time, helping ships avoid deadly strikes as gray whales appear in unusually high numbers. The day also brought a reminder of nature’s volatility: a magnitude 5.8 earthquake hit southern Peru late Tuesday, injuring 27 people and damaging buildings but causing no reported deaths. Together, the stories highlight both the vast scale of Earth’s living systems and the growing role of technology in monitoring and protecting them.
