Phys.org / Measuring chaos: Researchers quantify the quantum butterfly effect
For the first time, researchers in China have accurately quantified how chaos increases in a quantum many-body system as it evolves over time. Combining experiments and theory, a team led by Yu-Chen Li at the University of ...
Phys.org / Araish spiral galaxy observations uncover a 26,700-light-year radio jet
An international team of astronomers has performed multi-wavelength observations of the nearby Araish galaxy to investigate the origin of its radio emission. As a result, they detected an extended radio jet of this galaxy. ...
Phys.org / Ultra-stable lasers that rely on crystalline mirrors could advance next-generation clocks and navigation
Lasers, devices that emit intense beams of coherent light in specific directions, are widely used in research settings and are central components of various technologies, including optical clocks (i.e., systems that can keep ...
Medical Xpress / Recurrent prostate cancer: Two treatment strategies with uncertain outcomes compared
Imperial College London investigators compared focal therapy with prostate removal surgery for men with prostate cancer that returned after radiotherapy. Matched analyses estimated 10-year cancer-specific survival at 92% ...
Phys.org / How the humble silkworm could help us discover new anti-aging treatments
When scientists want to study aging and how to slow it down, they often turn to microscopic worms or lab mice among other models. The former are too different from humans, while the latter are expensive and take too long ...
Phys.org / Not all humans are 'super-scary' to wildlife, animal behavior study suggests
Humans have climbed to the top of the food chain by skillfully hunting, trapping, and fishing for other animals at scales that far exceed other predators, altering how the animals behave and earning the tag of a "super-predator." ...
Phys.org / The cooling system that lets bees beat the heat when hovering
To stay in the air when hovering over a flower, bumble bees continually flap their wings rapidly, a metabolic process that generates a massive amount of internal heat. Their flight muscles work so intensely that they can ...
Phys.org / Colonists dredged away Sydney's natural oyster reefs. Now, scientists know how best to restore them
New research has identified optimal design for artificial habitats to support restoration of oyster reefs, based on a detailed understanding of natural oyster reef geometry. Published in the global journal Nature, the Sydney-based ...
Phys.org / Antarctic ice melt can change global ocean circulation, sediment cores suggest
A new study shows that during the last two deglaciations, i.e., the transition from an ice age to the warm interglacial periods, meltwater from the Antarctic ice sheet intensified stratification in the Southern Ocean. The ...
Phys.org / How Indigenous ideas about nonlinear time can help us navigate ecological crises
It is common to think of time as moving in only one direction—from point A, through point B, to point C.
Medical Xpress / People prefer the empathy of humans, but rate 'fake' AI empathy higher
Artificial Intelligence (AI) agents, particularly the large language models (LLMs) underpinning the functioning of ChatGPT and other popular conversational platforms, are now used daily by millions of people worldwide. As ...
Tech Xplore / Personalization features can make LLMs more agreeable, potentially creating a virtual echo chamber
Many of the latest large language models (LLMs) are designed to remember details from past conversations or store user profiles, enabling these models to personalize responses. But researchers from MIT and Penn State University ...
