Phys.org / Changes to cougar diets and behaviors reduce their competition with wolves in Yellowstone, study finds
A new study shows that interactions between wolves and cougars in Yellowstone National Park are driven by wolves stealing prey killed by cougars and that shifts in cougar diets to smaller prey help them avoid wolf encounters. ...
Phys.org / Hearing angry or happy human voices is linked to changes in dogs' balance
In a small study, dogs experienced both stabilization and destabilization of their balance upon hearing angry or happy human voices, but angry voices were linked to the biggest destabilizing effects. Nadja Affenzeller and ...
Phys.org / From stellar engines to Dyson bubbles, alien megastructures could hold themselves together under the right conditions
New theoretical models have strengthened the case that immense, energy-harvesting structures orbiting their host stars could exist in principle in distant stellar systems. With the right engineering precautions, calculations ...
Phys.org / Amazon Leo satellites exceed brightness limits, study finds
Seeing a satellite zip across the night sky can be a fascinating sight. However, what may be spectacular for people on the ground is becoming a major problem for astronomers. A new study published on the arXiv preprint server ...
Phys.org / Pesticides significantly affect soil life and biodiversity, study finds
Seventy percent of soils in Europe are contaminated with pesticides. A Europe-wide study co-led by researchers of the University of Zurich now shows that their effects on soil life are substantial, as pesticides suppress ...
Phys.org / The Great Mongolian Road: Japanese Imperial Army maps reveal first detailed documentation
In a study published in the Journal of Historical Geography, researchers Dr. Chris McCarthy and his colleagues have documented, for the first time, the Great Mongolian Road, a major yet understudied east-west caravan route ...
Phys.org / AI model forecasts severe thunderstorms 4 hours ahead with higher accuracy
In a critical advance for climate resilience, researchers from The Hong Kong University of Science and Technology (HKUST) have developed an AI model that can predict dangerous convective storms—including Black Rainstorms, ...
Tech Xplore / AI can generate a feeling of intimacy that exceeds human connections
People can develop emotional closeness to artificial intelligence (AI)—under certain conditions, even more so than to other people. This is shown by a new study conducted by a research team led by Prof. Dr. Markus Heinrichs ...
Medical Xpress / Statins emerge as potential cancer immunotherapy boosters
Cancer immunotherapy has transformed modern oncology by harnessing the body's own immune system to combat malignant disease. Immune checkpoint inhibitors targeting the PD-1/PD-L1 pathway have produced durable responses in ...
Phys.org / Rare fossils reveal 91 new species that survived ancient mass extinction
Almost a hundred new animal species that survived a mass extinction event half a billion years ago have been discovered in a small quarry in China, scientists revealed Wednesday.
Phys.org / Chip-sized optical amplifier can intensify light 100-fold with minimal energy
Light does a lot of work in the modern world, enabling all types of information technology, from TVs to satellites to fiber-optic cables that carry the internet across oceans. Stanford physicists recently found a way to make ...
Phys.org / Jurassic amphibian with a projectile tongue named as a new species
A new species of amphibian that lived 150 million years ago has been discovered in Portugal. The tiny animal was one of the earliest species belonging to a mysterious group of amphibians that lived from the time of the dinosaurs ...
