Phys.org / Large-scale eDNA survey reveals hidden factors that affect regional fish communities
As climate change and human activities continually ramp up, fish are forced to find ways to adapt. As fish move around to find more suitable habitats as ocean conditions shift, regional fish distributions change—which can ...
Phys.org / What gives stevia its sweetness? Scientists uncover the genetic secret
Stevia is a widely used sweetener, but why do some stevia varieties taste cleaner and more sugar-like than others? Recent research conducted at the University of Toyama shows that stevia's sweetness is genetically linked ...
Tech Xplore / Co-designed robots reveal what health care staff and patients actually need
As robots enter hospitals and care facilities, questions remain about whether they actually make care easier for the people who give and receive it. A new Cornell Tech-led study approaches that challenge by inviting health ...
Tech Xplore / A single real-world data point may stop AI model collapse, analysis suggests
New work explaining the inner workings of artificial intelligence could provide a way around the threat of AI "model collapse," potentially averting growing numbers of AI hallucinations in the future.
Phys.org / Sex-related differences in hoverfly eyes give insight into their aerodynamic powers
Many male hoverflies have bigger eyes than females, giving them the advantage of better optics and faster photoreceptors in high-speed pursuits to find a preferred partner to breed.
Phys.org / We keep thanking machines and forests for one strange reason, and it is reshaping human bonds
Whether it's artificial intelligence programs or the Amazon rainforest, people often experience gratitude or protectiveness toward non-human entities because they perceive these entities as having good intentions, according ...
Phys.org / Meltwater flushed methane from Greenland seabed during ice-sheet retreat, researchers reveal
An international team of scientists has discovered that methane hydrates beneath the northwest Greenland continental shelf became rapidly destabilized by meltwater, releasing large stores of methane during ice-sheet retreat ...
Medical Xpress / Your voice changes when you're tired or exerting effort, and machines may soon use that signal
The "talk test" is often used as a low-tech way to measure exercise intensity: If you can easily talk or even sing, your workout is fairly light, but if conversation is difficult, you are exercising vigorously.
Tech Xplore / Designing better quantum circuits with AI
Researchers from the group of theoretical physicist Hans Briegel have collaborated with NVIDIA to develop an AI method that automatically generates efficient quantum circuits, a key bottleneck in making quantum computers ...
Tech Xplore / Signal-folding design helps neuromorphic chip slash AI energy use
Artificial intelligence systems, such as large language models (LLMs) and convolutional neural networks (CNNs), can analyze large amounts of data and rapidly generate desired content or identify meaningful patterns. However, ...
Medical Xpress / Fear memories fade faster when brain immune cells engage key neurons, study suggests
Post-traumatic stress disorder (PTSD) and anxiety disorders are often characterized by fearful responses in specific situations that the mind learns to view as threatening. These fearful responses typically emerge following ...
Science X / The ultimate viral stowaways: A Trojan Horse story
Forget hitchhiking; some tiny viruses are playing viral "Trojan Horse," literally sneaking inside other viruses to invade new species and even our brains. It's a microscopic masterclass in stealth infection.
