Phys.org / Nanoscale hairs may help gecko skin trap moisture and slow evaporation
In a dry shrubland, a gecko sprints toward shelter. Its greatest danger is not a predator, although hawks circle overhead and sand cats wait in ambush. Rather, its most pressing concern is dehydration. Its skin is paper-thin; ...
Phys.org / How chromosomes find their partners
For a long time, so-called satellite DNA was considered largely worthless. Now, ETH Zurich researchers have shown in fruit flies that these repetitive sections of genetic material act as a kind of barcode, enabling the correct ...
Tech Xplore / Who does AI consider an expert? New benchmark shows bias across 22 LLMs
AI chatbots powered by large language models (LLMs) are widely used as recommender systems. While accelerating access to information, AI can also give factually incorrect responses or propagate societal biases.
Phys.org / The hidden chemistry behind glow-in-the-dark art
Some of the world's brightest colors don't just reflect light; they create it. Scientists and museum conservators are now uncovering why these luminous pigments fade and how to preserve them for future generations. The findings ...
Medical Xpress / Mucus-coated tumor spheres reveal potential targets to curb colorectal cancer spread
Researchers from the University of Turku in Finland and Gustave Roussy Institute in France have discovered a molecular mechanism that regulates whether cells in an aggressive colorectal cancer are conventional or inverted ...
Phys.org / Why marine heat waves and acidification strike together
Marine heat waves and extreme ocean acidification events are each damaging on their own. But when both stressors hit simultaneously, their individual effects can be exacerbated.
Phys.org / Chatbots are making our writing more similar but losing the identity and personality behind it
Large language models (LLMs) are making writing styles more similar without changing the overall meaning, according to an analysis of more than 880,000 texts across different writing types published in Nature Human Behaviour. ...
Phys.org / LHC collisions reveal oxygen and neon's shifting nuclear geometry
Many people are aware that the Large Hadron Collider (LHC) at CERN smashes tiny subatomic particles together at nearly the speed of light to test foundational laws of physics and discover new fundamental particles, but some ...
Phys.org / Do customer loyalty programs actually work? The benefits are in the eye of the cardholder
Whether you love a loyalty discount at the supermarket or frequently forget your loyalty card, loyalty programs (LPs) can be an essential support for families and households amid growing cost-of-living pressures.
Medical Xpress / At least 1 in 4 former NFL players who died between 2016 and 2021 had CTE, study finds
In a new study from Mass General Brigham, Boston University (BU), and the Concussion & CTE Foundation, researchers found evidence that at least one in four former NFL players who died between 2016 and 2021 had chronic traumatic ...
Medical Xpress / Fundus images predict risk of hypertension and other systemic diseases
Researchers from Skoltech, the Z-union AI Technologies Consortium, Sber AI Lab and other research centers have proposed an artificial intelligence-based approach for the preventive screening of 15 diseases based on fundus ...
Medical Xpress / Research shows AI can fast track mental health care
Researchers have analyzed 1 million health-related Reddit threads to build an AI platform that can quickly identify mental health concerns in hopes that the findings will help fast-track and better personalize care.
