Phys.org / Scientists observe Einstein's gravity in the quantum world
An international team including Nobel Prize-winning physicist Professor Sir Roger Penrose has observed a long-predicted effect of gravity on a falling quantum object for the first time. The result shows that a fundamental ...
Dialog / A black hole as light as 40 tons can exist inside a star if dark matter helps
In 1974, Stephen Hawking made a prediction that transformed our understanding of black holes. Black holes, he showed, are not truly black: They slowly lose energy through a quantum process now known as Hawking radiation. ...
Phys.org / Some disagreement makes groups more trustworthy, mathematical framework finds
When humans are making decisions, they are known not to rely solely on their own considerations and the evidence available to them. Past behavioral science and psychology studies have shown that people are often also influenced ...
Phys.org / FAST finds two mysterious hydrogen clouds with no visible stars
Astronomers have found two clouds of hydrogen near the Whirlpool galaxy that appear to contain almost no stars. The clouds, discovered with China's FAST radio telescope, each contain roughly 3 million times the mass of the ...
Phys.org / Why doesn't Venus have a moon? A new study may have the answer
Venus is one of the solar system's most unusual planets. It may sometimes be called "Earth's twin" because of its similar size and density, but it rotates on its axis in the opposite direction of most planets, has surface ...
Phys.org / Levitated magnet opens new frontier in search for ultraheavy dark matter
Rice University researchers have used a magnetically levitated particle to search for ultraheavy dark matter, extending the hunt for some of the heaviest possible forms of the invisible matter thought to hold galaxies together. ...
Tech Xplore / Iron could make high-energy sodium-ion batteries last longer
Lithium-ion batteries (LiBs), which charge and discharge by moving lithium ions between two electrodes known as the cathode and anode, remain the most widely used rechargeable batteries worldwide. Over the past decades, however, ...
Medical Xpress / Scientists uncover shared biology behind profound fatigue in five major illnesses
A shared biological mechanism that helps explain chronic exhaustion in conditions including long COVID and PTSD has been identified by researchers at the University of East Anglia and Oxford BioDynamics. The paper, published ...
Phys.org / Betelgeuse's atmosphere is becoming spotty and asymmetric—and a nearby companion could be shaping the pattern
For the first time since its dramatic dimming in 2020, a team of astronomers has observed the inner atmosphere of Betelgeuse using the Atacama Large Millimeter Array (ALMA). Led by Bill Dent at the University of Manchester, ...
Medical Xpress / Study identifies key driver of inflammation, opening door to potential new treatments
Researchers at Johns Hopkins Medicine have uncovered a critical biological mechanism that helps explain how inflammation is triggered and sustained in a wide range of diseases—highlighting a promising avenue for future therapeutic ...
Phys.org / Interstellar travel V: Warp drives, wormholes, and halo drives
Welcome back to our series on Interstellar Travel, where we look at the many proposals made for sending missions to the stars since the dawn of the Space Age. In our first installment, we examined how Cold War-era developments ...
Medical Xpress / How cannabis legalization affects substance use
The legalization of cannabis affects substance use, with the potential for both negative and positive effects on public health, a new McGill-led study found.
