Medical Xpress / Large MRI analysis uncovers brain-region thinning tied to depression
Major depressive disorder (MDD) is a psychiatric condition characterized by persistent feelings of sadness, a loss of interest in everyday activities, altered sleeping and/or eating patterns, low energy, and difficulty concentrating ...
Phys.org / Primate evolution kept aging rates stable for 25 million years despite lifespan gaps
Biologists group animals with similar traits into broad categories called orders. Despite their similarities, animal species in the same order can have very different average lifespans.
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 ...
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. ...
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 / 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 ...
