Phys.org / Wave-like domain walls drive polarization switching in sliding ferroelectrics, study finds
Sliding ferroelectrics are a type of two-dimensional (2D) material realized by stacking nonpolar monolayers (atom-thick layers that lack an electric dipole). When these individual layers are stacked, they produce ferroelectric ...
Medical Xpress / Probe reliably records activity of large neuron populations in brains of non-human primates
To map the mammalian brain and its various functions with increasing precision, neuroscientists rely on high-resolution imaging techniques and other advanced experimental tools. These now include high-density silicon probes, ...
Phys.org / Using geometry and physics to explain feature learning in deep neural networks
Deep neural networks (DNNs), the machine learning algorithms underpinning the functioning of large language models (LLMs) and other artificial intelligence (AI) models, learn to make accurate predictions by analyzing large ...
Medical Xpress / More than a simple relay station: Thalamus may guide timing of brain development and plasticity
The brain is known to develop gradually throughout the human lifespan, following a hierarchical pattern. First, it adapts to support basic functions, such as movement and sensory perception, then it moves onto more advanced ...
Tech Xplore / Self-adaptive electrolytes expand stability for fast charging and high-energy batteries
To support the ongoing transition to electric vehicles and reduce greenhouse emissions, engineers have been trying to develop batteries that can store more energy, while also operating safely and lasting for long periods ...
Medical Xpress / New insights into how the visual system synchronizes visual information
The human brain builds mental representations of the world based on the signals and information detected via the human senses. While we perceive simultaneously occurring sensory stimuli as being synchronized, the generation ...
Tech Xplore / Robotic drummer gradually acquires human-like behaviors
Humanoid robots, robots with a human-like body structure, have so far been primarily tested on manual tasks that entail supporting humans in their daily activities, such as carrying objects, collecting samples in hazardous ...
Phys.org / LLMs can predict educational and psychological outcomes from childhood essays with remarkable accuracy
Large language models (LLMs), advanced artificial intelligence (AI) models trained to analyze and generate texts in different human languages, have become increasingly widespread over the past few years. Since the release ...
Tech Xplore / Maximizing direct methanol fuel cell performance: Reinforcement learning enables real-time voltage control
Fuel cells are energy solutions that can convert the chemical energy in fuels into electricity via specific chemical reactions, instead of relying on combustion. Promising types of fuel cells are direct methanol fuel cells ...
Tech Xplore / A low-cost catalytic cycle could advance the separation, storage and transportation of hydrogen
Hydrogen (H2) is an Earth-abundant molecule that is widely used in industrial settings and could soon contribute to the clean generation and storage of electricity. Most notably, it can be used to generate electricity in ...
Phys.org / Neutrino masses are not likely to originate from interactions with dark matter, study finds
Neutrinos are fundamental particles characterized by no electric charge and very small masses, which are known to interact with other matter via the weak force or gravity. While these particles have been the focus of numerous ...
Phys.org / Internal pair production could enable direct detection of dark matter
Dark matter (DM) is a type of matter estimated to account for 80% of the universe's total mass, but it cannot be directly detected using conventional experimental techniques. As DM does not emit, reflect or absorb light, ...
Tech Xplore / Freestanding hafnium zirconium oxide membranes can enable advanced 2D transistors
To further reduce the size of electronic devices, while also improving their performance and energy efficiency, electronics engineers have been trying to identify alternative materials that outperform silicon and other conventional ...
Tech Xplore / New strategy can directly pattern 2D materials into high-quality wafer-scale arrays
Two-dimensional (2D) semiconductors, materials that can conduct electricity and are only a few atoms thick, are promising alternatives to the conventional silicon-based semiconductors currently used to fabricate many electronics. ...
Medical Xpress / Brain scans reveal parahippocampal cortex thinning in those with depression and neuroticism
Depression is a mental health disorder characterized by a recurrent or persistent sadness and a loss of interest in activities that were previously deemed pleasurable, sometimes accompanied by changes in sleep, appetite and ...
