Phys.org / Physicist delineates limits on the precision of quantum thermal machines
Quantum thermal machines are devices that leverage quantum mechanical effects to convert energy into useful work or cooling, similarly to traditional heat engines or refrigerators. Thermodynamics theory suggests that increasing ...
Phys.org / The body's molecular mail revealed: Scientists decode blood's hidden messengers
Every second, trillions of tiny parcels travel through your bloodstream—carrying vital information between your body's cells. Now, scientists at the Baker Heart and Diabetes Institute have opened this molecular mail for ...
Medical Xpress / Lung cancer should no longer be defined by fear and stigma, experts say
For decades, lung cancer has been associated with stigma, anxiety, and loss. Advances in screening, therapeutics, and survivorship have created a new reality; lung cancer is treatable, survivable, and increasingly understood ...
Phys.org / Entanglement-enhanced optical lattice clock achieves unprecedented precision
Optical lattice clocks are devices that measure the passing of time via the frequency of light that is absorbed or emitted by laser-cooled atoms trapped in a repeating pattern of light interference known as optical lattice.
Phys.org / Rapid X-ray pulses enable 100-fold efficiency boost for photoionization
Speed matters. When an X-ray photon excites an atom or ion, making a core electron jump onto a higher energy level, a short-lived window of opportunity opens. For just a few femtoseconds, before an electron fills the void ...
Medical Xpress / Mini lung organoids made in bulk could help test personalized cancer treatments
A team of scientists have developed a simple method for automated manufacturing of lung organoids which could revolutionize the development of treatments for lung disease. These organoids, miniature structures containing ...
Phys.org / Diamond defects, now in pairs, reveal hidden fluctuations in the quantum world
In spaces smaller than a wavelength of light, electric currents jump from point to point and magnetic fields corkscrew through atomic lattices in ways that defy intuition. Scientists have only ever dreamed of observing these ...
Phys.org / Astronomers capture an exceptional gamma-ray flare from a blazar
Astronomers have performed very long baseline interferometry (VLBI) observations of a gamma-ray loud blazar known as TXS 2013+370. The observations, posted November 19 on the arXiv preprint server, resulted in the detection ...
Medical Xpress / Eye washing may ease hay fever ocular symptoms and improve quality of life
Hay fever, also known as allergic rhinitis, is the condition responsible for seasonal allergies or allergic reactions to other environmental allergens, like dust mites and animal dander. Estimates vary, but somewhere around ...
Tech Xplore / Humanoid robots reliably manipulate different objects with 87% success using new framework
Robotic systems that mirror humans both in their appearance and movements, also known as humanoid robots, could be best suited for tackling many tasks that are currently performed by human agents. These include household ...
Medical Xpress / Clinical use of nitrous oxide could help treat depression, major study shows
Patients with major depressive disorder, including those who have not responded to first-line antidepressants, may benefit from short-term nitrous oxide treatment, a major meta-analysis led by the University of Birmingham ...
Phys.org / Six strategies identified to help households cut down on food waste
Researchers from the Center for Food Policy at City St George's, University of London and Scotland's Rural College have set out six key areas for action that could help households cut down on food waste in a new comment article ...
