Phys.org / JWST pins down the origins of a planetary odd couple
Across the Milky Way galaxy, a planetary odd couple is circling a star some 190 light years from Earth. A normally "lonely" hot Jupiter is sharing space with a mini-Neptune, in a rare and unlikely pairing that's had astronomers ...
Phys.org / Physics-based weather models more accurate than AI at predicting extreme weather
Weather forecasting is another aspect of modern life that artificial intelligence is transforming. Models like GraphCast, Pangu-Weather, and Fuxi are already better than traditional physics-based climate models at predicting ...
Phys.org / Three billion years ago, Earth's life relied on a rare metal
A collaborative team of scientists has discovered that life on Earth over three billion years ago relied on the metal molybdenum, which was incredibly scarce in the environment at the time. The study, published in Nature ...
Phys.org / Why isolated human groups speak more diverse languages even as genetic diversity shrinks
Languages and human DNA both capture aspects of human diversity. But how are they related? A new international study led by the University of Zurich finds a clear but counterintuitive pattern: regions with high genetic diversity ...
Phys.org / Unraveling the evolution of an extraordinary photosynthesis in a tropical tree species
Plants use sunlight to convert water and carbon dioxide into energy-rich sugars and oxygen in various ways (photosynthesis). Drought is a major challenge in this process. A research team led by Wolfram Weckwerth at the University ...
Phys.org / Carnivorous plants and wasps blur the line between friend and food
Acid-filled pitchers complete with fangs. Labyrinthine chambers decorated with bristles. Leaves that snap shut in less than a second. Employing strategies like these, carnivorous plants have a reputation as fearsome predators, ...
Phys.org / Watch as NASA's Curiosity Rover frees its drill from a rock
This series of images shows NASA's Curiosity Mars rover as it got a rock stuck to the drill on the end of its robotic arm, and—after waving the arm and running the drill a few times—finally detached the rock. The imagery ...
Phys.org / Inexpensive material compresses light, paving the way for photonic microcircuits in the terahertz range
A two-dimensional lamellar crystal composed of atomically thin layers of lead iodide (PbI2) could be used to manufacture a new generation of circuits that use light and mechanical vibrations (rather than electrons) to transmit ...
Phys.org / What if the brain came first? Scientist rethinks the Cambrian Explosion
For decades, scientists have sought to explain the so-called "Cambrian Explosion," a pivotal period over 500 million years ago when a remarkable diversity of animal life appeared in the fossil record. But rather than a sudden ...
Phys.org / As sargassum floods Florida beaches, researchers uncover new use as food-grade ingredient
As record-breaking amounts of sargassum seaweed drift toward Florida's shores, researchers at Florida International University are exploring how the coastal nuisance could become a valuable ingredient in everyday foods.
Phys.org / CPR simulator for space use tracks the differences of blood flow in reduced gravity
The new focus on manned missions to the moon and Mars presents countless pressing challenges, including keeping humans alive in hostile environments. What happens when an astronaut or space tourist has a cardiac emergency ...
Phys.org / A skull full of surprises: Discovering the evolutionary secrets of fish brains
A new study in Proceedings of the Royal Society B reveals the surprising neurological landscape of fish brains. Harvard researchers map the internal structures of ray-finned fishes' brains in 3D detail, discovering brain ...
