Phys.org / Solid-state material turns visible light into high-energy UV at sunlight intensity, expanding solar energy potential
Two cups of warm water don't make one cup of boiling water. But in the quantum world, multiple low-energy photons can combine to produce a single, higher-energy photon.
Phys.org / Contact lenses can repair themselves with just one hour of UV light exposure
Contact lenses are a great vision correction option for many, but if one of them gets damaged, there is little to do other than throw it away. A team reporting in ACS Applied Polymer Materials has a solution: special polymer ...
Phys.org / Attitudes, not personality, may drive deepfake pornography creation
New research from Edith Cowan University (ECU) suggests attitudes, particularly those that excuse harmful behavior, may be a stronger predictor of willingness to create deepfake pornography than personality traits. The findings ...
Tech Xplore / Researchers find 'trap' hindering performance of hybrid perovskites
A new study from Cornell researchers has revealed an unexpected obstacle to improving charge transport in hybrid perovskites, a promising class of semiconductor materials used in energy conversion and electronic devices. ...
Medical Xpress / Recovering from an injury can be all-consuming. Researchers are using VR to make injury recovery less stressful
When Maria Chiu began her Ph.D. at Northeastern University in 2023, she never expected to become her own research subject. She also didn't anticipate undergoing her fourth knee surgery.
Medical Xpress / Spontaneous and voluntary laughter come from two different brain regions, researchers reveal
Laughter is a universal social signal that connects us with others, but the brain regions underlying laughter are not well understood, in part because it's hard to elicit genuine laughter in the lab.
Phys.org / Espresso 'pucks' stop behaving predictably above certain pressures
When a physics student asked baristas at the Warsaw Coffee Conference what their biggest question for scientists was, the baristas said they wanted to know how to stop channeling during brewing.
Phys.org / Corrected Pantheon+ analysis of supernovae challenges accelerating universe claim
Research led by the Tata Institute of Fundamental Research, Mumbai, along with Professor Subir Sarkar from the University of Oxford, questions the widely accepted argument that the expansion rate of the universe is accelerating ...
Phys.org / Amazon fish reveal a synchronized survival tactic that could transfer to drone swarms
Some fish swim in synchrony. Others, it turns out, breathe in synchrony. This is true for arapaimas, an obligate air-breathing species living in the Amazon. A new study in Communications Biology, led by the Leibniz Institute ...
Medical Xpress / New framework renders AI more trustworthy for cancer subtyping
Medical artificial intelligence (AI) faces a fundamental challenge: uncertainty quantification. Artificial neural networks are largely unaware of the limits of their training data and can become overconfident when confronted ...
Phys.org / Local species trends may flag global extinction risk, global study finds
New research from the University of St. Andrews has shown that higher extinction risk is associated with a higher frequency of decreasing local prevalence of species, in an analysis of one of the most comprehensive long-term ...
Medical Xpress / How privilege shaped families' ability to stay healthy during COVID-19
Money, social networks and access to information are resources that are frequently available to privileged groups or classes in society, helping them weather tough times and adversity. Drawing on interviews with families ...
