Dialog / Near a black hole, gravity changes a quantum circuit's readings, not its rules
Imagine holding one of our most precise quantum devices at a fixed position outside a black hole. A Josephson junction—two superconductors separated by an ultrathin barrier—can turn a voltage into a quantum oscillation with ...
Medical Xpress / Working memory rapidly updates its priorities after distractions, study finds
When humans tackle many everyday tasks, ranging from driving to completing household chores and work assignments, they rely heavily on working memory. This is the brain's ability to temporarily store and manipulate important ...
Phys.org / Gamma-ray pulsations reveal extreme 3.2-millisecond pulsar 3,900 light-years away
By analyzing the data from NASA's Fermi gamma-ray space telescope, Chinese astronomers have investigated a recently identified millisecond pulsar known as PSR J0435+3233. As a result, they found that the pulsar exhibits gamma-ray ...
Phys.org / A quantum heat engine that simultaneously provides work and refrigeration
The laws of thermodynamics state that heat naturally flows from hotter systems or regions to colder systems or regions until a state of thermal equilibrium is reached. This simple principle underpins the operation of numerous ...
Phys.org / Twisted laser light distinguishes mirror-image molecules by their fragment counts
Many molecules exist in two mirror-image forms—like left and right hands—that look identical but can behave very differently, especially in biological systems and pharmaceuticals. Distinguishing between these enantiomers ...
Phys.org / Angola's oldest burials, including its only known ancient cremation, uncovered at a 15th-century site doomed by a dam
As the construction of a hydroelectric dam loomed, archaeologists raced to uncover Angola's earliest dated burials and its only known cremation at a 15th-century settlement before it vanished beneath the water.
Phys.org / Forest productivity, not rapid warming, shapes Northern Eurasia's carbon sink
Northern Eurasia contains about 20% of the world's forests and plays a crucial role in mitigating climate change by absorbing atmospheric carbon dioxide, thereby acting as a major carbon sink. However, understanding the region's ...
Tech Xplore / 3D-printable material can heal the body, build better robots and recover critical minerals
A new type of 3D-printable material developed by researchers at The University of Texas at Austin mimics human tissue's ability to sort and filter, allowing certain molecules to pass through while keeping others out. This ...
Phys.org / Trace molecules emerge as chemical 'keystones' that steer life's communities
In nature, the rarest ingredient can be the one that holds everything together. In a new article published in Trends in Ecology & Evolution, Dr. Erika C. Freeman of the Leibniz Institute of Freshwater Ecology and Inland Fisheries ...
Medical Xpress / A tax on sugary drinks in Egypt could reduce disease and save US$1.8 billion in health care costs: Modeling study
Noncommunicable diseases—heart disease, stroke, diabetes, cancer—are no longer just a rich-country problem. Across Africa, they are becoming the leading cause of death, driven in part by a simple and overlooked culprit: what ...
Phys.org / When a teenager makes the 'stupid choice,' their brain is working exactly as designed
When an adult refuses to let an injustice pass—stands up to a bully or asserts their rights—we call it principle. When a 15-year-old retaliates to an insult thrown in a school corridor, risking detention, we call it a failure ...
Medical Xpress / Testosterone and combat readiness: What does the evidence really show?
Pete Hegseth, the U.S. defense secretary, recently announced plans to measure testosterone levels in U.S. soldiers with a promise of "ensuring you have the right testosterone levels to operate at your absolute best." Soldiers ...
