Phys.org / How Earth's mantle locked away vast amounts of water in early magma ocean
Some 4.6 billion years ago, Earth was nothing like the gentle blue planet we know today. Frequent and violent celestial impacts churned its surface and interior into a seething ocean of magma—an environment so extreme that ...
Phys.org / Record-breaking cosmic explosion challenges astronomers' understanding of gamma-ray bursts
Astronomers at the University of North Carolina at Chapel Hill have helped uncover new clues about the longest-lasting cosmic explosion ever observed, a gamma-ray burst that lasted nearly seven hours. The event, known as ...
Phys.org / Chip-scale magnetometer uses light for high-precision magnetic sensing
Researchers have developed a precision magnetometer based on a special material that changes optical properties in response to a magnetic field. The device, which is integrated onto a chip, could benefit space missions, navigation ...
Phys.org / Quantifying unknown quantum states: Study explores effectiveness of existing methods
Reliably quantifying and characterizing the quantum states of various systems is highly advantageous for both quantum physics research and the development of quantum technologies. Quantifying these states typically entails ...
Phys.org / Graphene membranes offer efficient, low-cost option for industrial CO₂ capture
Carbon capture is becoming essential for industries that still depend on fossil fuels, including the cement and steel industries. Natural-gas power plants, coal plants, and cement factories all release large amounts of CO₂, ...
Tech Xplore / Transistor 'design limitation' actually improves performance, scientists find
What many engineers once saw as a flaw in organic electronics could actually make these devices more stable and reliable, according to new research from the University of Surrey and Joanneum Research Materials.
Phys.org / Dual substitution induces room-temperature ferromagnetism and negative thermal expansion in BiFeO₃
Using a dual-cation substitution approach, researchers at Science Tokyo introduced ferromagnetism into bismuth ferrite, a well-known and promising multiferroic material for next-generation memory technologies. By replacing ...
Phys.org / DNA confirms modern Bo people are descendants of ancient Hanging Coffin culture
In a recent study, researcher Dr. Hui Zhou and his colleagues conducted a genetic analysis of the genomes of individuals associated with the ancient Hanging Coffin tradition in Southeast and Southern Asia. In addition, they ...
Phys.org / Small galaxies may buck the black hole trend, Chandra finds
Most smaller galaxies may not have supermassive black holes in their centers, according to a recent study using NASA's Chandra X-ray Observatory. This contrasts with the common idea that nearly every galaxy has one of these ...
Phys.org / Unlocking the sun's magnetic secrets: AI-powered mapping reveals intricate 3D details
Researchers at the University of Hawaiʻi Institute for Astronomy (IfA) are helping reshape how scientists study the sun. The UH-led team has developed a new artificial intelligence (AI) tool that can map the sun's magnetic ...
Phys.org / Astronomers challenge 50-year-old quasar law
Compelling evidence that the structure of matter surrounding supermassive black holes has changed over cosmic time has been uncovered by an international team of astronomers.
Medical Xpress / Plant used in folk medicine has anti-inflammatory anti-arthritic effects, study confirms
In Brazil, researchers from the Federal University of Grande Dourados (UFGD), the State University of Campinas (UNICAMP), and São Paulo State University (UNESP) have conducted a study that confirmed the safety and anti-inflammatory, ...
