Published A 'quantum leap' at room temperature



Scientists have achieved a milestone by controlling quantum phenomena at room temperature.
Published Interactions between flu subtypes predict epidemic severity more than virus evolution



Researchers have shed new light on how viral evolution, population immunity, and the co-circulation of other flu viruses shape seasonal flu epidemics.
Published How ancient sea creatures can inform soft robotics



Fossils of a marine animal that lived 500 million years ago, combined with computer simulations, informed the design of a new soft robot.
Published The hidden rule for flight feathers -- and how it could reveal which dinosaurs could fly



Scientists examined hundreds of birds in museum collections and discovered a suite of feather characteristics that all flying birds have in common. These 'rules' provide clues as to how the dinosaur ancestors of modern birds first evolved the ability to fly, and which dinosaurs were capable of flight.
Published Researchers show classical computers can keep up with, and surpass, their quantum counterparts



A team of scientists has devised means for classical computing to mimic a quantum computing with far fewer resources than previously thought. The scientists' results show that classical computing can be reconfigured to perform faster and more accurate calculations than state-of-the-art quantum computers.
Published How teachers make ethical judgments when using AI in the classroom



A teacher's gender and comfort with technology factor into whether artificial intelligence is adopted in the classroom, as shown in a new report.
Published Dinosaurs' success helped by specialized stance and gait, study finds



Dinosaurs' range of locomotion made them incredibly adaptable, researchers have found.
Published Microfluidic environments alter microbe behaviors, opening potential for engineering social evolution



A research group explored how the social evolution of microbes can be manipulated by tuning the physical parameters of the environment in which they live.
Published New species of Jurassic pterosaur discovered on the Isle of Skye



A new species of pterosaur from specimens found on the Isle of Skye, Scotland, has been announced.
Published One person can supervise 'swarm' of 100 unmanned autonomous vehicles



Research involving has shown that a 'swarm' of more than 100 autonomous ground and aerial robots can be supervised by one person without subjecting the individual to an undue workload.
Published Smells like evolution: Fruit flies reveal surprises in chemical sensing



New study reveals how gene expression shapes the diverse smelling and tasting abilities of different fly species. Most genes are surprisingly stable, but thousands have evolved to create unique olfactory landscapes. Sex differences in sensing are widespread and involve specific cell types in key tissues. The study provides insights into the evolution of sensory systems in general, with potential implications for understanding human olfaction.
Published How food availability could catalyze cultural transmission in wild orangutans



The proverb "necessity is the mother of invention" has been used to describe the source from which our cultural evolution springs. After all, need in times of scarcity has forced humans to continually invent new technologies that have driven the remarkable cumulative culture of our species. But an invention only becomes cultural if it is learned and spread by many individuals. In other words, the invention must be socially transmitted. But what are the forces that drive social transmission?
Published Rare 3D fossils show that some early trees had forms unlike any you've ever seen



In the fossil record, trees typically are preserved with only their trunks. They don't usually include any leaves to show what their canopies and overall forms may have looked like. In a new study, researchers describe fossilized trees from New Brunswick, Canada with a surprising and unique three-dimensional crown shape.
Published AI learns through the eyes and ears of a child



Researchers have been skeptical that recent AI advances can tell us much about human learning and development. To address this, a team training an AI model, not on massive data, but on the input that a single child receives. Their findings showed that the model could learn a substantial number of words and concepts using limited slices of what the child experienced.
Published Plant receptors that control immunity and development share a common origin



Researchers have traced the origin and evolutionary trajectory of plant immune receptors. Their discovery will make it easier to identify immune receptor genes from genomic information and could help in the development of pathogen-resistant crops.
Published Scientists pinpoint growth of brain's cerebellum as key to evolution of bird flight



Evolutionary biologists report they have combined PET scans of modern pigeons along with studies of dinosaur fossils to help answer an enduring question in biology: How did the brains of birds evolve to enable them to fly?
Published 'Genomic time machine' reveals secrets of our DNA



Researchers reveal a novel method to uncover bits of our genetic blueprint that come from ancient genetic parasites, offering fresh insights into human evolution and health.
Published How did humans learn to walk? New evolutionary study offers an earful



A new study, which centers on evidence from skulls of a 6-million-year-old fossil ape, Lufengpithecus, offers important clues about the origins of bipedal locomotion courtesy of a novel method: analyzing its bony inner ear region using three-dimensional CT-scanning. The inner ear appears to provide a unique record of the evolutionary history of ape locomotion.
Published How does a 'reverse sprinkler' work? Researchers solve decades-old physics puzzle



For decades scientists have been trying to solve Feynman's Sprinkler Problem: How does a sprinkler running in reverse work? Through a series of experiments, a team of mathematicians has figured out how flowing fluids exert forces and move structures, thereby revealing the answer to this long-standing mystery.
Published Researchers map genome for cats, dolphins, birds, and dozens of other animals



Researchers mapped genetic blueprints for 51 species including cats, dolphins, kangaroos, penguins, sharks, and turtles, a discovery that deepens our understanding of evolution and the links between humans and animals. The researchers developed novel algorithms and computer software that cut the sequencing time from months -- or decades in the case of the human genome -- to a matter of days.
