Phys.org / New framework suggests dark energy could be evolving—and may be linked to the Hubble tension
A team of cosmologists in China has introduced a mathematical framework that investigates two of the deepest mysteries in cosmology at the same time. Publishing their research in The Astrophysical Journal, Yun Chen and colleagues ...
Phys.org / Human sperm may get lost in space
Having a baby in space may require a bit more direction, with new Adelaide University research revealing the navigational abilities of sperm are negatively impacted by a lack of gravity. Researchers at the University's Robinson ...
Phys.org / Hubble detects first-ever spin reversal of tiny comet
Astronomers using NASA's Hubble Space Telescope have found evidence that the spinning of a small comet slowed and then reversed its direction of rotation, offering a dramatic example of how volatile activity can affect the ...
Phys.org / Dual-rail superconducting qubits generate high-fidelity logical entanglement, study finds
Quantum computers, systems that process information leveraging quantum mechanical effects, could outperform classical computers on some advanced tasks. These systems rely on qubits, the fundamental units of quantum information, ...
Phys.org / Nitrile and latex gloves may cause overestimation of microplastics in the lab
Nitrile and latex gloves that scientists wear while they are measuring microplastics may lead to a potential overestimation of the tiny pollutants, according to a University of Michigan study, published in Analytical Methods.
Phys.org / Giant virus DNA may help polar algae survive harsh environments
In the game of survival, you can't always go it alone. Tiny algae living in the harsh conditions of the world's polar oceans appear to be better able to withstand the cold, high salinity, and extreme UV radiation, thanks ...
Phys.org / Israel's 'Stonehenge' no longer stands alone: Satellite technology opens archaeological frontiers
For decades, the massive stone circles of Rujm el-Hiri in the Golan Heights were considered a singular, mysterious anomaly—often dubbed "Israel's Stonehenge." However, new research led by Ben-Gurion University of the Negev ...
Phys.org / Novel measurement confirms a 50-year-old prediction: Dark points are faster than light
A research group from the Technion-Israel Institute of Technology reports in Nature an unprecedented achievement in electron microscopy: the direct measurement of "dark points" within light waves. By doing so, the researchers ...
Phys.org / Independent measurement strengthens the case for toponium
A new independent measurement by the CMS experiment at the LHC is consistent with the existence of the most massive composite particle ever observed, the momentary union of a top quark and its antiquark
Phys.org / Medieval DNA reveals trans-Saharan connections, rapid genetic mixing and leprosy in Islamic Ibiza
Medieval Ibiza was far from a quiet Mediterranean backwater. New DNA evidence shows that the island was part of a dynamic world linking Europe, North Africa and even the Sahel zone, south of Sahara. An international research ...
Phys.org / Light-activated nanoparticles trigger copper overload to kill cancer cells
Cuproptosis was discovered in 2022. It was a previously unknown type of cell death caused by an excess of copper. The research group led by Professor Johannes Karges at Ruhr University Bochum, Germany, used this mechanism ...
Phys.org / Experimental evidence shows how photons spread across multiple paths in an interferometer
The nature of quantum particles has long puzzled scientists. While single-particle interference suggests that a photon can behave like a spread-out wave, a whole photon is only ever detected in one specific place. Traditional ...
