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 / Quantum experiment shows events may have no fixed order
For the first time, a team of physicists in Austria has carried out an experiment that appears to verify the principle of indefinite causal order: an idea that suggests that timelines of events can exist in multiple orders ...
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 / 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 / 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 / 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 / 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 / Why cells respond 'incorrectly' in old age
Some of the signs of aging in human cells originate in the cell nucleus, because the packaged form of DNA changes with age. This has now been demonstrated by PSI researchers. It means that older cells can no longer react ...
Phys.org / Study finds 40% of European gas stoves leak cancer-causing benzene while turned off
Benzene, a compound linked with leukemia and other blood cancers, is leaking from gas stoves in Europe, a new study finds. According to the World Health Organization, there is no safe level of exposure to benzene, a compound ...
Phys.org / Sediment core reveals 10,800 years of precipitation history in the Sahara
The analysis of a sediment core from an oasis lake in Chad provides new insights into the history of precipitation in the Sahara. The study, led by the University of Cologne, shows that a prolonged wet phase, which lasted ...
