The forecast is bright for future, long-term multiband monitoring of planets Imaging data from Japan’s Himawari-8 and -9 meteorological satellites have been successfully used to monitor temporal changes in Venus’ cloud-top temperature, revealing unseen patterns in the temperature structure of various waves. A team led by the University of Tokyo collated infrared images from 2015–25 to estimate brightness temperatures on day to year scales. The results demonstrate that meteorological satellites can serve as additional eyes to access the Venusian atmosphere…

Chipmunk and vole skulls from over 125 years reflect changes in diet and noise exposure In general, evolution is a long, slow process of tiny changes passed down over generations, resulting in new adaptations and even new species over thousands or millions of years. But when living things are faced with dramatic shifts in the world around them, they sometimes rapidly adapt to better survive. Scientists recently found an example of evolution in real time, tucked away in the collection…

Discovery reveals pulsing mantle plume beneath Ethiopia, where a new ocean is forming Research led by Earth scientists at the University of Southampton has uncovered evidence of rhythmic surges of molten mantle rock rising from deep within the Earth beneath Africa. These pulses are gradually tearing the continent apart and forming a new ocean. The findings, published in Nature Geoscience, reveal that the Afar region in Ethiopia is underlain by a plume of hot mantle that pulses upward like a…

Research shows these channels allow seawater and nutrients to flow in and out, helping to maintain reef health over millions of years. Volcanic islands, such as the islands of Hawaii and the Caribbean, are surrounded by coral reefs that encircle an island in a labyrinthine, living ring. A coral reef is punctured at points by reef passes — wide channels that cut through the coral and serve as conduits for ocean water and nutrients to filter in and out. These…
