Phys.org / A thermodynamic approach to gravity could explain cosmic acceleration without dark energy
Gravity, the force that attracts objects toward each other, is currently framed by Albert Einstein's theory of general relativity. This framework describes gravity as the curvature of spacetime, the invisible four-dimensional ...
Medical Xpress / A species of gut bacteria could ease anxiety and diarrhea-predominant IBS
Irritable bowel syndrome (IBS) is a condition characterized by abdominal pain, bloating and changes in bowel movements, estimated to affect between 10% and 15% of people worldwide. Past studies suggest that in many cases ...
Phys.org / Quantum waves reveal one-sided motion marking elusive critical states
Sound waves, light waves and other types of waves, generally spread freely through space and over time. In 1958, physicist Philip W. Anderson first described a phenomenon via which irregularities or other sources of disorder ...
Phys.org / Artificial DNA tiles could deliver drugs and monitor neurons non-disruptively
Living cells constantly exchange ions (i.e., charged particles) via the thin barrier that surrounds their interior, known as the outer membrane. Neuroscientists and medical researchers have long been trying to devise effective ...
Phys.org / Interlayer self-doping could unlock room-temperature multiferroics in atom-thin materials
Multiferroics are materials that exhibit more than one prominent "ferroic" property, such as ferromagnetism and ferroelectricity. One of their most advantageous features is that they allow engineers to control their magnetic ...
Tech Xplore / Brain-inspired AI architecture could compute faster while using far less power
Spiking neural networks (SNNs) are artificial intelligence (AI) models inspired by how biological neurons communicate with each other. While biological neurons exchange information in the form of electrical impulses, SNNs ...
Phys.org / Horizon edge states gain finite description in string theory calculation
Modern physics theories highlight the key role of horizons—boundaries beyond which information cannot reach an observer—in a variety of cosmological and gravitational phenomena. Two renowned examples of these boundaries are ...
Medical Xpress / Coordinated brainstem slow waves may determine when it's time for REM sleep
Sleep is one of the most widely studied states of consciousness, known to play a role in physical recovery, the processing of memories and the regulation of immune functions. During sleep, the brain transitions between light ...
Phys.org / Marmoset monkeys adapt their voices to sound more like their social partners, study finds
Many animal species that live in groups are known to adjust their behavior to strengthen their social bonds or increase their coordination with others around them. For instance, humans and some other animals exhibit vocal ...
Medical Xpress / Clues to psilocybin's epigenetic effects on people with alcohol use disorder
Some psychedelics, psychoactive substances that alter people's mood, perceptions and mental processes, were recently found to be promising alternative treatments for some mental health disorders. The substance that has attracted ...
Medical Xpress / Three genes may link six mental disorders through shared biomarkers
Different neuropsychiatric and neurodevelopmental conditions, such as schizophrenia, bipolar disorder, attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD), are characterized by highly distinct ...
Phys.org / Tiny objects swimming in a superfluid of light move against the flow
Superfluids are intriguing states of matter in which particles behave like a giant collective wave, allowing them to flow without any friction. When this fluid flows past a fixed obstacle at a velocity below a specific threshold, ...
Tech Xplore / Drones learn to squeeze through narrow gaps using onboard AI control
Unmanned aerial vehicles (UAVs), commonly known as drones, are now widely used for various purposes, ranging from filmmaking and aerial photography to industrial inspection, precision farming and reaching obstructed areas ...
Medical Xpress / People consciously recognize the meaning of words they can no longer see, study finds
When humans are awake, they are typically aware of specific sounds, movements, objects and other stimuli in their surroundings. Most of these are stimuli that they can see, hear or perceive with any of their other senses.
Tech Xplore / Spin-orbit torque hardware creates random keys and reveals unauthorized access attempts
The information exchanged by modern devices is typically protected by cryptographic techniques, approaches that convert readable data into scrambled, unreadable code that can only be deciphered by authorized parties or devices. ...
