Phys.org / Ultraluminous X-ray source in Whale galaxy investigated for spectral and timing variability
Astronomers from Germany and Turkey have analyzed available data from various space telescopes to investigate an ultraluminous X-ray source designated X-4, which is located in the nearby galaxy NGC 4631. Results of the new ...
Phys.org / Pacific plate's rotation gave Alaska's Aleutian Islands a later-life lift
New research by Brown University geologists confirms that the Aleutian Islands, the archipelago stretching from Alaska to Russia's Kamchatka Peninsula, experienced a massive geological uplift between 5 million and 7 million ...
Tech Xplore / Dog-bone design helps 2D nanoribbon transistors stay fast and efficient as widths shrink
Transistors, small semiconductor-based switches that control the flow of electricity, are central components of all electronic devices, from computers to smartphones, wearables, sensors and smart appliances. Over the past ...
Tech Xplore / An AI model that thinks like we do offers new ways to peer inside the black box
When a standard large language model (LLM) is confronted with a problem, it tries to solve it by matching it to similar information it has seen before, and then give an answer based on those past patterns. But how it decides ...
Medical Xpress / New tool helps uncover rare genetic mutations in common diseases, including Parkinson's
Studies of genetics conducted in yeast cells, human neurons, mice or other model systems often reveal networks of genes that could contribute to complex diseases, such as breast cancer, type 2 diabetes and Parkinson's disease. ...
Medical Xpress / Some patient groups are far more vulnerable to near-perfect privacy attacks from medical AI
From detecting pneumonia on a chest X-ray to assessing whether a dark spot on the skin is benign or malignant, medical AI systems are playing an increasingly important role in clinical diagnosis. Unfortunately, the models ...
Tech Xplore / Artificial skin enables robots to simultaneously sense temperature and pressure like humans
A research team led by Prof. Seung Hwan Ko of Seoul National University College of Engineering's Department of Mechanical Engineering has developed an artificial skin technology that enables robots to sense temperature and ...
Medical Xpress / Serious statin muscle side effects are rare for most people, new calculator shows
Researchers at the Nuffield Department of Primary Care Health Sciences, University of Oxford, have developed a new calculator that estimates a person's risk of developing serious muscle disorders from statins. The tool could ...
Phys.org / Chemically primitive galaxy from 13 billion years ago reveals record-low oxygen
An international team of astronomers has used the James Webb Space Telescope (JWST) and a natural phenomenon known as gravitational lensing to achieve a definitive characterization of LAP1-B, an ultra-faint galaxy from 13 ...
Phys.org / Metal hydride molecule trapped with laser light opens path to ultracold hydrogen
Controlling and trapping molecules, units of a substance consisting of two or more chemically bound atoms, with laser light is significantly more challenging than trapping individual atoms. This is because molecules exhibit ...
Phys.org / European heatwave's unlikely accomplice: An ocean 'cold blob'
The heat wave battering Europe may have an unlikely partner in crime: a patch of cold ocean water south of Iceland and Greenland that can influence weather patterns over the continent.
Medical Xpress / Bioresorbable implant electrically stimulates organs, nerves and muscles then vanishes after treatment
To treat or manage various heart, gastrointestinal and neurological conditions, including arrhythmias, heart block, gastroparesis, epilepsy and some nerve injuries, doctors rely on a technique known as electrical stimulation. ...
