Phys.org / When biology inspires mathematics: Hidden symmetries explain why widely used evolutionary methods can give false answers
Why do some groups of organisms contain thousands of species while others have only a handful? Evolutionary biologists have spent decades trying to answer this question using mathematical models that estimate how biological ...
Phys.org / Weak sea-surface temperature gradients may fuel stronger tropical cyclones
The fact that the ocean gets colder as you go deeper is fairly intuitive, but a similar gradient exists along the surface of the ocean, even at scales of 1 kilometer to tens of kilometers. A new study, published in the Proceedings ...
Phys.org / Sorry, this neutrino laser won't work, physicists say
Neutrinos are pervasive yet intangible particles that permeate the universe, streaming through whole planets, stars and our bodies by the trillions each second. The elementary particles are often described as "ghostly" for ...
Phys.org / Iguanodon shinbone growth may be first evidence of an infected skin ulcer in a dinosaur
Fossilized bones can reveal a wealth of details about animals, including their size, appearance, what they ate and any injuries they may have suffered. In a paper published in the journal Royal Society Open Science, researchers ...
Medical Xpress / Runner's high study finds cannabis-like signaling molecules rise over extreme distances
A marathon, 100 kilometers (62 miles) or even 230 kilometers (143 miles) in a single effort: Anyone running such distances puts enormous strain on their body. At the same time, levels of the body's own cannabis-like signaling ...
Tech Xplore / Personality pairing improves human-AI collaboration
While artificial intelligence (AI) is receiving increased attention for its potential to improve productivity and performance, results can vary widely across different tasks, industries and individuals. Developers can now ...
Phys.org / Young sunlike system reveals comets may carry water toward forming planets
Astronomers at Lund University in Sweden have found evidence of exocomets—comets in other solar systems—orbiting a young star similar to our sun. The observations point to a possible mechanism for how water might be transported ...
Phys.org / Whether you're an introvert or extravert may decide how you should use AI
More than a century ago, the Swiss psychiatrist Carl Jung made introversion and extraversion central to his theory of psychological types.
Medical Xpress / Understanding the neural processes underlying limb apraxia
Limb apraxia is a neurological disorder that can occur after damage to the brain's left hemisphere and is characterized by difficulty using tools despite normal motor control and cognition. It affects roughly a quarter of ...
Phys.org / Dolphin-feeding tourism contributes to predicted dolphin decline
A study published in the journal Oikos, titled "Forecasting the impact of food-provisioning and other stressors on a marine top-predator population," found that without protective management, the Indo-Pacific bottlenose dolphin ...
Medical Xpress / ECG-based AI algorithm could improve detection and prediction of heart diseases
Clinicians often use a medical test called a 12-lead electrocardiogram (ECG) to diagnose heart problems. It uses electrodes placed on the chest and limbs to record the heart's electrical activity. Artificial intelligence ...
Medical Xpress / Top US doctors offer updated flu and COVID vaccine recommendations, aiming to ease confusion
Leading U.S. medical groups are urging people to get updated flu and COVID-19 vaccinations this fall, banding together Wednesday to issue shot guidelines—and highlight the science behind them—saying they hope to ease confusion ...
