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 / 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 / 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 / It's complicated: New research reveals more about the social networks of baboons and African monkeys
Like people, nonhuman primates live in groups that vary in size and shape depending on the species. Some primate groups are small and simple; others are large and more layered. Over the decades, primatologists have observed ...
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 / Magnetic fields can 'revive' superconductivity in nickelates, research reveals
A research team led by Professor Denver Li Danfeng, Associate Dean (Research and Postgraduate Education) of the College of Science and Associate Professor in the Department of Physics at City University of Hong Kong (CityUHK), ...
Phys.org / Polar vortex forecasts gain months of lead time with new climate-based method
Florida State University researchers have discovered how to accurately predict winter weather forecasts months in advance, affording sectors such as agriculture, water management, energy use and public health a longer lead ...
Phys.org / Tiny eggs may explain why ammonites vanished while nautiloids survived asteroid aftermath
Some of the most beautiful creatures to grace the ancient seas, the ammonites, disappeared in the end-Cretaceous mass extinction that finished off the dinosaurs 65.5 million years ago. "It's a tragic story, because this incredibly ...
Phys.org / Understanding how lasers can rapidly magnetize fusion plasmas
The mechanism that can cause a rapidly expanding plasma—the superhot state of matter harnessed in fusion energy systems—to spontaneously generate its own magnetic fields was identified through a new set of simulations. This ...
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 / 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 / Timor green pigeon 'likely to go extinct' without urgent action, according to scientists
The Timor green pigeon, which is under pressure from hunting and habitat loss, is at serious risk of extinction and should be uplisted to Critically Endangered, according to a new study from researchers at Charles Darwin ...
