Phys.org / Simulating the Hawking effect and other quantum field theory predictions with polariton fluids
Quantum field theory (QFT) is a physics framework that describes how particles and forces behave based on principles rooted in quantum mechanics and Albert Einstein's special relativity theory. This framework predicts the ...
Phys.org / IceCube neutrino search sets first constraints on proton fraction of ultrahigh-energy cosmic rays
Neutrinos are subatomic particles with no charge and very little mass that are known to weakly interact with other matter in the universe. Due to their weak interactions with other particles, these particles are notoriously ...
Phys.org / A new method to measure ultrafast relaxation processes in single molecules
Quantum stochastic rectification is a process observed in some physical systems, which entails the conversion of random quantum fluctuations (i.e., quantum noise) and a small oscillating signal, such as a weak alternating ...
Medical Xpress / Study maps changes in brain's 'neural noise' from childhood to adulthood
For over a century, neuroscientists and psychologists have been trying to understand the neurophysiological mechanisms underpinning the human brain's development from birth to late adulthood. While past studies have shed ...
Phys.org / New approach to engineering crumpled GO membranes for separating hydrogen and other gases
The reliable separation of some gases from others could be highly advantageous for a wide range of applications. For instance, it could help to produce hydrogen (H2) for fuel cells and chemical applications or to capture ...
Phys.org / Researchers uncover a topological excitonic insulator with a tunable momentum order
Topological materials are a class of materials that exhibit unique electronic properties at their boundary (surface in 3D materials; edge in 2D materials) that are robust against imperfections or disturbances and are markedly ...
Medical Xpress / Human CLOCK gene enhances brain connectivity and mental flexibility in mice, study finds
Clock genes are a set of genes known to contribute to the regulation of the human body's internal 24-hour cycle, also known as the circadian rhythm. One of these genes is the so-called CLOCK gene, a protein that regulates ...
Tech Xplore / A human-inspired pathfinding approach to improve robot navigation
For robots to be successfully introduced in a wider range of real-world settings, they should be able to safely and reliably navigate rapidly changing environments. While roboticists and computer scientists have introduced ...
Phys.org / New scheme mitigates self-discharging in quantum batteries
Quantum batteries (QBs) are energy storage devices that could serve as an alternative to classical batteries, potentially charging faster and enabling the extraction of more energy. In contrast with existing batteries, these ...
Tech Xplore / New memristor-based system could boost processing of radiofrequency signals
The development of more advanced technologies to process radiofrequency signals could further advance wireless communication, allowing devices connected to the internet to share information with each other faster and while ...
Medical Xpress / Genetic variants linked with higher risk of developing bipolar disorder
Bipolar disorder is a mental health condition characterized by extreme mood swings, with alternating periods of depression and manic episodes. Past research suggests that bipolar disorder has a strong genetic component and ...
Medical Xpress / Electrical stimulation of facial muscles influences how people perceive others' emotions, study finds
Psychology research suggests that the human body, particularly the muscles on our face, plays a key part in the processing of others' emotions. For instance, past findings suggest that when we see another person smiling or ...
Tech Xplore / New reconfigurable memristor-based system enables in-memory data sorting
Organizing data in a specific order, also known as sorting, is a central computing operation performed by a wide range of systems. Conventional hardware systems rely on separate components to store and sort data, which limits ...
Phys.org / LUX-ZEPLIN experiment sets more stringent constraints on cosmic ray-boosted dark matter
Dark matter, a type of matter that does not emit, absorb, or reflect light, is predicted to account for most of the universe's mass. While theoretical predictions hint at its abundance, detecting this elusive matter has so ...
Tech Xplore / New scrubbing robot could contribute to automation of household chores
While the advent of robotic systems that can complete household chores has been widely anticipated, those commercially released so far are primarily robot vacuums that autonomously clean the floor. In contrast, robots that ...
