Phys.org / Scientists discover a hidden RNA 'aging clock' in human sperm
Increasing paternal age has been linked to elevated health risks for the next generation, including higher risks of obesity and stillbirth. But what drives this increased risk remains unknown.
Phys.org / Pūkeko birds combine sound elements to create complex call sequences for communication, study reveals
Pūkeko use sound elements to create calls and combine them to create complex call sequences in order to expand the range of options for expressing themselves—these are the findings of an international team including Konstanz ...
Phys.org / Get ready for smokier air: Record 2023 wildfire smoke marks long-term shift in North American air quality
A new analysis of air quality data from the past 70 years shows that Canada's record wildfire smoke in 2023 is part of a broader, continent-wide trend toward smokier skies across North America.
Phys.org / Water makeup of Jupiter's Galilean moons set at birth, new study finds
While Io, the most volcanically active moon in the solar system, appears completely dry and devoid of water ice, its neighbor Europa is thought to harbor a vast global ocean of liquid water beneath its icy crust. A new international ...
Phys.org / ChatGPT found to reflect and intensify existing global social disparities
New research from the Oxford Internet Institute at the University of Oxford, and the University of Kentucky, finds that ChatGPT systematically favors wealthier, Western regions in response to questions ranging from "Where ...
Phys.org / Beyond chemistry: How mechanical forces shape brain wiring
During brain development, neurons extend long processes called axons. Axons link different areas of the brain and carry signals within it and to the rest of the body. Growing axons "wire up" the brain by following precise ...
Phys.org / Intricacies of Helix Nebula revealed with Webb
NASA's James Webb Space Telescope has zoomed into the Helix Nebula to give an up-close view of the possible eventual fate of our own sun and planetary system. In Webb's high-resolution look, the structure of the gas being ...
Phys.org / Previously unknown chemical pathway for air pollution particle formation uncovered
An atmospheric scientist at The University of Alabama in Huntsville (UAH), a part of The University of Alabama System, has helped uncover a previously unknown chemical pathway that plays a major role in the formation of air ...
Phys.org / Direct visualization captures hidden spatial order of electrons in a quantum material
The mystery of quantum phenomena inside materials—such as superconductivity, where electric current flows without energy loss—lies in when electrons move together and when they break apart. KAIST researchers have succeeded ...
Phys.org / Hot spring bathing doesn't just keep snow monkeys warm—it can disrupt lice distribution and reshape gut bacteria
Japanese macaques, colloquially referred to as snow monkeys, famously soak in steaming hot springs during winter. It's easy to see that this helps them stay warm in cold temperatures, but a team of researchers at Kyoto University ...
Phys.org / A century's worth of data could help predict future solar cycle activity
Research conducted by an international team of astronomers from Southwest Research Institute, Aryabhatta Research Institute of Observational Sciences in India and the Max Planck Institute in Germany could help predict upcoming ...
Phys.org / Seawater microbes offer new, non-invasive way to detect coral disease
Researchers at the Woods Hole Oceanographic Institution (WHOI), in collaboration with the University of the Virgin Islands have discovered that microorganisms in seawater surrounding corals provide a powerful indicator of ...
