Tech Xplore / Soft magnetoelastic sensor measures fatigue from eyeball movements in real-time
Over the past few decades, electronics engineers have developed increasingly sophisticated sensors that can reliably measure a wide range of physiological signals, including heart rate, blood pressure, respiration rate and ...
Medical Xpress / Genetic deletion in cerebellum impedes hemisphere formation, study finds
The cerebellum, a brain region located at the back of the head that has long been known to support the coordination of muscle movements, has recently also been implicated in more sophisticated mental functions. Purkinje cells ...
Phys.org / QROCODILE experiment advances search for dark matter using superconducting nanowire single-photon detectors
Over the past decades, many research teams worldwide have been trying to detect dark matter, an elusive type of matter that does not emit, reflect or absorb light, using a variety of highly sensitive detectors. Ultimately, ...
Medical Xpress / Distinct psilocybin-induced oscillations observed in rat medial prefrontal cortex, with effects lasting days
Psychedelics, a class of psychoactive drugs that typically induce peculiar mental states and hallucinations, are still prohibited for recreational use in most countries worldwide. In recent years, some neuroscientists and ...
Phys.org / Physicists demonstrate controlled expansion of quantum wavepacket in a levitated nanoparticle
Quantum mechanics theory predicts that, in addition to exhibiting particle-like behavior, particles of all sizes can also have wave-like properties. These properties can be represented using the wave function, a mathematical ...
Tech Xplore / Rolling soft electronics yields 3D brain probes for precise neuron mapping
To shed new light on the contribution of different brain regions and neural circuits to specific mental functions, neuroscientists and medical researchers rely on advanced imaging techniques and neural probes. These are electronic ...
Medical Xpress / Theory proposes key role for cortex layer 6b in attention and advanced mental functions
A layer deep in the cerebral cortex, which is the innermost layer of the mammalian brain, has recently been found to play a role in the regulation of brain states associated with wakefulness and attention.
Phys.org / The Hofstadter butterfly: Twisted bilayer graphene reveals two distinct strongly interacting topological phases
Magic-angle twisted bilayer graphene (MATBG) is a material created by stacking two sheets of graphene onto each other, with a small twist angle of about 1.1°. At this "magic angle," electrons move very slowly, which can lead ...
Medical Xpress / New insights into the epigenetic processes via which neuroinflammation causes memory loss
Neuroinflammation, a prolonged activation of the brain's immune system prompted by infections or other factors, has been linked to the disruption of normal mental functions. Past studies, for instance, have found that neuroinflammation ...
Phys.org / Gold-enhanced TiO₂ catalyst enables efficient and selective flow synthesis of propane from methane
Methane (CH₄), the colorless and odorless gas that makes up most natural gas on Earth, has so far been converted into useful fuels and chemicals via energy-intensive processes that need to be carried out at high temperatures. ...
Phys.org / Polaritons enable tunable and efficient molecular charge transfer across broader spectrum of light
Polaritons are quasiparticles emerging from strong interactions between light particles (i.e., photons) and matter excitations (e.g., excitons). Over the past few years, researchers have found that these quasiparticles can ...
Medical Xpress / Pancreatic insulin disruption triggers bipolar disorder-like behaviors in mice, study shows
Bipolar disorder is a psychiatric disorder characterized by alternating episodes of depression (i.e., low mood and a loss of interest in everyday activities) and mania (i.e., a state in which arousal and energy levels are ...
Medical Xpress / Dopamine signaling in nucleus accumbens may shape confidence in decision-making
Decision-making, the process through which humans choose between different available options, has been the topic of countless neuroscience, psychology and behavioral science studies. This process does not only include the ...
Medical Xpress / Comprehensive molecular atlas of human hippocampus maps cell subtypes and organization
The hippocampus is an important brain region known to support various cognitive (i.e., mental) processes, including the encoding and retrieval of memories, learning, decision-making and the regulation of emotional states. ...
Medical Xpress / People's brain structure linked to their genetic risk of major depression, study finds
Depression is among the most widespread psychiatric disorders, experienced by an estimated 3.8% of the global population. It is characterized by persistent low mood and a loss of interest in most activities, as well as possible ...
