Aurora rails: In northern Norway, a new overnight train has been built with one goal in mind, letting passengers watch the Northern Lights while they travel. Instead of standard windows, the cars are wrapped in glass, including the ceiling, so the sky stays in view from every seat. The interior lighting is kept low to avoid reflections, making it easier to see faint movement outside. The route runs through areas already known for strong aurora activity, turning the journey itself into the main attraction. Designed as an alternative to daytime sightseeing, the train pairs slow travel with night skies. For travelers, it offers an immersive way to experience the aurora from a moving viewpoint.
Reef voices: Coral reefs are alive with clicks, pops, and low noises, but it’s been hard to tell which fish make which sounds. A new tool solves that by recording audio and video together, letting researchers match a sound to the fish seen making it. The system uses underwater microphones paired with a wide-view camera, so crowded reef scenes are easier to sort out. Early recordings showed that many fish make sounds scientists didn’t know about before. Those identified noises are added to a shared library for future study. Over time, the recordings can be checked without divers returning to the site. Researchers say listening this way could become a simple way to track reef activity and changes.
