Medical Xpress / Genetic underpinnings of substance use disorders in Europe, Africa and America identified, some previously unknown
Substance use disorders (SUDs) are mental health conditions characterized by the compulsive, uncontrolled and deleterious use of alcohol, tobacco, stimulants (e.g., cocaine or methamphetamines), opioids, cannabis and/or various ...
Tech Xplore / Three-layer microfluidic cooling device can remove heat from small electronics more efficiently
As electronic devices become increasingly powerful and compact, they can generate denser heat fluxes, or in other words, produce more heat in a smaller area. These heat fluxes raise the temperature of a device and can damage ...
Phys.org / How social norms evolved over time and differ across countries
When humans interact with each other and engage in everyday activities, they typically follow various undefined rules, also known as social norms. These rules include things like greeting acquaintances in specific ways upon ...
Tech Xplore / DeepMind introduces AI agent that learns to complete various tasks in a scalable world model
Over the past decade, deep learning has transformed how artificial intelligence (AI) agents perceive and act in digital environments, allowing them to master board games, control simulated robots and reliably tackle various ...
Medical Xpress / Astrocyte-derived vesicles could link stress to intestinal inflammation
Inflammatory bowel diseases (IBDs), such as Crohn's disease and ulcerative colitis, are chronic and autoimmune conditions characterized by the inflammation of the intestinal tract. This inflammation can cause nausea or vomiting, ...
Tech Xplore / Isotropic MOF coating reduces side reactions to boost stability of solid-state Na batteries
In recent years, energy engineers have been trying to design new reliable batteries that can store more energy and allow electronics to operate for longer periods of time before they need to be charged. Some of the most promising ...
Phys.org / Simulations hint at new strongly correlated states of matter in ultracold polar molecules
Bose-Einstein condensates (BECs) are fascinating states of matter that emerge when atoms or molecules are cooled to extremely low temperatures just slightly above absolute zero (0 K). In 2023, physicists at Columbia University ...
Medical Xpress / Family and peer conflicts predict teenage mental health issues, study finds
Identifying the factors that contribute to psychopathology and increase the risk of experiencing specific mental health conditions is a long-standing goal for many psychology researchers. While past studies have highlighted ...
Tech Xplore / Novel carbon nanotube-based transistors reach THz frequencies
Carbon nanotubes (CNTs), cylindrical nanostructures made of carbon atoms arranged in a hexagonal lattice, have proved to be promising for the fabrication of various electronic devices. In fact, these structures exhibit outstanding ...
Tech Xplore / New organic thin-film tunnel transistors for wearable and other small electronics
To meet the growing demands of flexible and wearable electronic systems, such as smart watches and biomedical sensors, electronics engineers are seeking high-performance transistors that can efficiently modulate electrical ...
Phys.org / Exploring how dark matter alters electron-capture supernovae and the birth of neutron stars
Electron-capture supernovae (ECSNe) are stellar explosions that occur in stars with initial masses around 8–10 times that of the sun. These stars develop oxygen-neon-magnesium cores, which become unstable when electrons are ...
Tech Xplore / Humans and LLMs represent sentences similarly, study finds
Psychologists and behavioral scientists have been trying to understand how people mentally represent, encode and process letters, words and sentences for decades. The introduction of large language models (LLMs) such as ChatGPT, ...
Phys.org / Graphene partially screens van der Waals interactions depending on layer thickness, study reveals
Two-dimensional (2D) materials, which are only a few atoms thick, are known to exhibit unique electrical, mechanical and optical properties, which differ considerably from the properties of bulk materials. Some recent studies ...
Medical Xpress / Study unveils mechanisms driving axonal accumulation of TDP-43 and associated nerve damage in ALS
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by progressive muscle wasting and limb paralysis. This neurodegenerative condition results from the gradual destruction of motor neurons, the ...
Medical Xpress / Grid cells create multiple local maps rather than single global system for spatial navigation, study finds
Grid cells are a class of specialized neurons in a brain region called the entorhinal cortex, which is known to support spatial navigation and some memory processes. Past neuroscience studies have found that as humans and ...
