Phys.org / North Sea 'lost world' had habitable forests during the last Ice Age, study shows
Forests were growing on the now-submerged landmass of Doggerland thousands of years earlier than previously believed, according to a major new sedimentary ancient DNA (sedaDNA) study led by the University of Warwick. The ...
Phys.org / Friendly fungi hijack plant regulator to promote symbiosis
Plants are constantly on guard. Their roots are equipped with molecular alarm systems that detect invading microbes and trigger immune responses. Yet beneficial soil fungi routinely enter living root cells and establish close ...
Phys.org / Bromacker deposit is 4 million years older than previously thought, new dating reveals
Analysis of a volcanic ash tuff layer, only a few millimeters thick and discovered during excavations in 2024, revealed that the fossil-bearing Bromacker rocks are 294 million years old—four million years older than previously ...
Phys.org / New African species confirms evolutionary origin of magic mushrooms
A long-standing debate about the evolutionary origin of the world's most widely cultivated "magic mushroom"—Psilocybe cubensis—may now have been settled by scientists from southern Africa and the United States.
Phys.org / Acoustic driving enables controlled condensation of light and matter on chip
An international research team led by Alexander Kuznetsov at the Paul Drude Institute for Solid State Electronics (PDI) in Berlin has demonstrated a fundamentally new way to control the condensation of hybrid light-matter ...
Medical Xpress / The timing of rewards plays a key role in learning, study finds
For almost a century, psychology and neuroscience researchers have been trying to understand the processes via which humans and other animals acquire new skills or learn to deal with specific situations. One well-known and ...
Medical Xpress / Why street layouts may matter for aging brains: Brain scans link walkability to memory
The simple act of crossing a road could help shield the brain from dementia and other cognitive conditions, according to new research from the Australian Catholic University and UNSW Sydney's Center for Healthy Brain Aging ...
Tech Xplore / AI assistants can sway writers' attitudes, even when they're watching for bias, experiments indicate
Artificial intelligence-powered writing tools such as autocomplete suggestions can definitely change the way people express themselves, but can they also change how they think? Cornell Tech researchers think so.
Phys.org / Trouble swallowing? A nanogel tweak may keep therapeutic stem cells alive longer
Swallowing is a fundamental human function that supports nutrition and communication. Damage to swallowing muscles can reduce quality of life and even lead to aspiration pneumonia or malnutrition. Many patients suffer from ...
Phys.org / Precisely measuring quantum signals in large spin ensembles
Quantum mechanical effects are known to be easily disrupted by disturbances from the surrounding environment, commonly referred to as noise. To minimize these disturbances, physicists often study these effects in small and ...
Tech Xplore / Brain-inspired device could lead to faster, more energy-efficient AI hardware
A team led by engineers at the University of California San Diego has developed a new brain-inspired hardware platform that could help computer hardware keep pace with the explosive growth of artificial intelligence. By combining ...
Phys.org / What primate faces reveal about empathy: Humans mirror emotions across species
Humans perceive emotional expressions displayed by non-human primates and spontaneously mimic these expressions, according to a study published in the open-access journal PLOS One by Ursula Hess from Humboldt University of ...
