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 ...
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. ...
Medical Xpress / Blood test 'clocks' can predict when Alzheimer's symptoms will start
Researchers at Washington University School of Medicine in St. Louis have developed a method to predict when someone is likely to develop symptoms of Alzheimer's disease using a single blood test. In a study published in ...
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 ...
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 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.
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 / 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 / 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 ...
Medical Xpress / Low-field MRI is safe, feasible and more comfortable for breast screening, finds study
Researchers at Mass General Brigham have demonstrated the technical feasibility of using ultra-low field (ULF) magnetic resonance imaging (MRI) for breast imaging. With further refinement and evaluation, the technology could ...
Tech Xplore / Choosing experiments randomly can help scientists develop better theories, new model reveals
The race to develop a virtual scientist—an AI creation that conducts every stage of research, from idea to publication—has consumed researchers, start-up founders, and tech juggernauts alike.
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 ...
