Phys.org / Rare 567‑million‑year‑old fossils refine our understanding of early animal evolution
From butterflies to blue whales, corals and worms, Earth is home to an incredible diversity of animals. How all of these animals evolved from earlier, simpler ancestors is one of the most exciting stories in the history book ...
Medical Xpress / Handwriting speed may be a sign of cognitive decline in older people
Handwriting requires a combination of fine motor control and a complex set of mental skills, such as selecting, organizing, and interpreting sensory information, making it a cognitively challenging task. Because of its high ...
Phys.org / How climate change is destroying Arctic cultural heritage sites
Climate change is rapidly destroying cultural heritage sites across the Arctic, as exemplified in a 17th century "whalers' graveyard" which provides invaluable insights into early whalers' way of life, according to a study ...
Phys.org / AI not yet good enough to grade university essays, rewarding 'style over substance'
Researchers have used top Generative AI models to grade hundreds of undergraduate essays and found that AI only matched human-awarded degree classification around half the time, with AI often failing to accurately assess ...
Phys.org / Rising seawater heat may collapse coral oxygen flow before bleaching appears
Tropical coral reefs support the highest levels of biodiversity in the ocean. This vital ecosystem depends on reef-building corals, which form colonies of thousands of tiny coral animals that secrete calcium carbonate skeletons, ...
Tech Xplore / Watching the detectors: Researchers probe efficacy—and danger—of AI detection tools
Patrick Traynor, Ph.D., has questions. When the professor and interim chair of the University of Florida Department of Computer & Information Science & Engineering saw reports in the media positing that scientific literature ...
Medical Xpress / Strong genetic mutation overrides female protective effects in autism, researchers discover
Autism spectrum disorder affects males far more frequently than females, with diagnoses occurring roughly four times more often in boys. Scientists have long suspected that females may possess biological protective mechanisms ...
Phys.org / Long-serving CEOs may weaken innovation, study finds
A new study from the University of East London has found that companies led by long-serving chief executives may become less innovative over time unless challenged by strong independent boards. The research examined 215 FTSE ...
Phys.org / Genes without borders: Coral babies can travel vast distances across the Pacific Ocean
The offspring of a common coral branching species set up a new home up to 100 kilometers or more from their parents in one of the longest dispersal distances ever measured, according to new international research.
Phys.org / Why some water fleas suddenly grow helmets: Key receptors reveal how predator warnings trigger defense
Daphnia, commonly known as water fleas, are tiny crustaceans that live in freshwater ponds and lakes. When they sense predators in their surroundings, these small organisms can swiftly move away or adapt their body shape, ...
Phys.org / AtLAST, a telescope that could reveal the missing half of the universe
A new European-led telescope could map the dusty, hidden half of the universe, all without using fossil fuels. If you have ever seen the Milky Way in the night sky, you probably noticed that it looks cloudy. That is because ...
Phys.org / Insects in the city: Flowers alone may not be enough to sustain them
What renders a city garden attractive to insects such as solitary bees, bumblebees and hoverflies? And how well do they pollinate plants in urban areas? A study by the Federal Research Institute for Forest, Snow and Landscape ...
