Phys.org / How big can a planet be? With very large gas giants, it can be hard to tell
Gas giants are large planets mostly composed of helium and/or hydrogen. Although these planets have dense cores, they don't have hard surfaces. Jupiter and Saturn are the gas giants in our solar system, but there are many ...
Phys.org / Quantum dots reveal entropy production, a key measure of nanoscale energy dissipation
In order to build the computers and devices of tomorrow, we have to understand how they use energy today. That's harder than it sounds. Memory storage, information processing, and energy use in these technologies involve ...
Phys.org / Can't tally love: Tracking favors may hurt relationship, research indicates
They say that love is a two-way street, but that may only hold true to a point. It turns out that couples who obsess over equal give-and-take may be sabotaging their relationship, suggests a study involving University of ...
Tech Xplore / Platforms that rank the latest LLMs can be unreliable
A firm that wants to use a large language model (LLM) to summarize sales reports or triage customer inquiries can choose between hundreds of unique LLMs with dozens of model variations, each with slightly different performance. ...
Phys.org / Friendly encounters and nature make international exchange students happy in Finland
Smooth everyday services, a safe environment, and small, friendly encounters with locals are key factors that increase the happiness of international students in Finland. This is shown by a recent study conducted at the University ...
Medical Xpress / Overlooked group of gut bacteria appears key to good health, global study finds
In a huge global study led by University of Cambridge researchers, a single group of bacteria—named CAG-170—has repeatedly shown up in high numbers in the gut microbiomes of healthy people. CAG-170 is a group of gut bacteria ...
Medical Xpress / New study reveals gaps in Apple Watch's ability to detect undiagnosed high blood pressure
In September 2025, the U.S. Food and Drug Administration cleared the Apple Watch Hypertension Notifications Feature, a cuffless tool that uses the watch's optical sensors to detect blood flow patterns and alert users when ...
Medical Xpress / Can medical AI lie? Large study maps how LLMs handle health misinformation
Medical artificial intelligence (AI) is often described as a way to make patient care safer by helping clinicians manage information. A new study by the Icahn School of Medicine at Mount Sinai and collaborators confronts ...
Medical Xpress / Obesity linked to one in 10 infection deaths globally
Just over one in 10 deaths from a wide range of infectious diseases can be attributed to obesity worldwide, finds a major new study led by a University College London (UCL) researcher. People with obesity face a 70% higher ...
