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 / 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 / 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 / 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 / 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 / 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 / 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 ...
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 / 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 / Tiny insect brain discovery offers a blueprint for faster and more efficient AI and robots
The secret behind insects' lightning-fast reactions could offer a blueprint for more energy-efficient robots and self-driving cars, according to a new study challenging our understanding of how brains process information. ...
Phys.org / Planet 9 volunteers double known population of brown dwarfs
A new paper from NASA's Backyard Worlds: Planet 9 project announces that volunteers have essentially doubled the number of known brown dwarfs, with over 3,000 new discoveries made over the past 10 years since the project ...
Phys.org / Dog training choices may reflect owners' ethical views on animals
Whether a dog owner rewards their dog with a treat or corrects it by pulling on the leash is not simply a matter of what they believe to be the most effective training method. According to the study, owners' choice of training ...
