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 ...
Tech Xplore / New Mn-rich cathode could improve sustainability and stability of high-energy Li-ion batteries
Lithium-ion batteries (LiBs) remain the most widely used rechargeable batteries worldwide, powering most portable and consumer electronics. LiBs are also used to power most electric and hybrid vehicles, which are predicted ...
Phys.org / Hybrid metasurface modulates light at low voltages for energy-efficient optics
Metasurfaces are two-dimensional (2D), nanoengineered surfaces that interact strongly with electromagnetic waves and can control light with remarkable precision. These ultra-thin layers can be used to develop a wide range ...
Phys.org / Simplified Sachdev-Ye-Kitaev model simulated on trapped-ion quantum computer
The simulation of strongly interacting many-body systems is a key objective of quantum physics research, as it can help to test the predictions of physics theories and yield new valuable insight. Researchers at Quantinuum, ...
Phys.org / Algorithm precisely quantifies flow of information in complex networks
Networks are systems comprised of two or more connected devices, biological organisms or other components, which typically share information with each other. Understanding how information moves between these connected components, ...
Tech Xplore / Promising medium can capture and convert carbon dioxide, while regenerating itself for reuse
Over the past decades, energy researchers have developed various promising solutions to limit the emission of greenhouse gases and source fuels or other chemicals more sustainably. These solutions include so-called carbon ...
Tech Xplore / 3D-printed microrobots adapt to diverse environments with modular design
Microrobots, small robotic systems that are less than 1 centimeter (cm) in size, could tackle some real-world tasks that cannot be completed by bigger robots. For instance, they could be used to monitor confined spaces and ...
Medical Xpress / Preventing overhydration: Study uncovers a neural circuit that prompts mice to stop drinking
Identifying the neural mechanisms that support the regulation of vital physiological processes, such as drinking, eating and sleeping, is a long-standing goal within the neuroscience research community. As the disruption ...
Phys.org / Ultrasensitive sensor maps magnetization textures in rhombohedral graphene
Graphene, which is comprised of a single layer of carbon atoms arranged in a hexagonal lattice, is a widely used material known for its advantageous electrical and mechanical properties. When graphene is stacked in a so-called ...
Tech Xplore / Low-power MoS₂-based microwave transmitter could advance communications
To further advance wireless communication systems, electronics engineers have been trying to develop new electronic circuits that operate in the microwave frequency range (1–300 GHz), while also losing little energy while ...
