A study in Current Biology has found that artificial light spilling into coastal waters can disrupt sleep in coral reef fish, change their nighttime behavior and leave biological signs linked to brain health. The research, led by scientists at Bar-Ilan University, shows how the glow from cities, ports, roads and hotels can reach below the…

Researchers at the University of California, Los Angeles used computer models to test a hotter view of the solar system’s two outer planets. Their arXiv study, submitted to The Astrophysical Journal, proposes that Uranus and Neptune may contain enormous hydrogen-rich magma oceans below their familiar blue clouds. The idea could reshape how scientists picture these…
A study in Biological Reviews has found that freshwater browning is reshaping fish communities in northern lakes. The research links darker water with slower growth in many fish and with major differences in which species become more common. In many unstocked lakes, that shift could mean fewer trout, bass, perch and whitefish. It could also…
A study in Nature has uncovered a hidden Arctic chain reaction: debris-filled icebergs are carrying rocks away from melting glaciers and dropping them onto the deep seafloor, where they can become rare footholds for bottom-dwelling life. The work links changes in land ice to changes in deep-sea biodiversity hundreds of kilometers from the glaciers where…
