Phys.org / Astronomers examine nuclear star cluster of nearby galaxy Messier 74
By analyzing the data from the PHANGS-MUSE survey, an international team of astronomers has inspected a nuclear star cluster of the nearby large spiral galaxy Messier 74. The new study presented Dec. 3 on the arXiv pre-print ...
Phys.org / Ear piercings marked one of the earliest Maya rites of passage, research shows
In a recent study, Ph.D. candidate Yasmine Flynn-Arajdal studied iconographic representations of children in the Classic (ca. 250–950 AD) and Post-classic (ca. 950–1539 AD) imagery, as well as in ethnohistoric and ethnographic ...
Phys.org / Tiny optical modulator could enable giant future quantum computers
Researchers have made a major advance in quantum computing with a new device that is nearly 100 times smaller than the diameter of a human hair.
Phys.org / Polar bears may be adapting to survive warmer climates, says study
New research reveals a link between rising temperatures and changes in polar bear DNA, which may be helping them adapt and survive in increasingly challenging environments.
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 / 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 / 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, ...
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 / Biphenomycin biosynthetic pathway decoded, opening door to new antibiotic development
Biphenomycins, natural products derived from bacteria, show excellent antimicrobial activity, but have long remained out of reach for drug development. The main obstacle was the limited understanding of how these compounds ...
Phys.org / Enhancing machine-learning interatomic potentials for advanced materials modeling
Machine learning is transforming many scientific fields, including computational materials science. For about two decades, scientists have been using it to make accurate yet inexpensive calculations of interatomic potentials, ...
Phys.org / Break the mold: Who defines the 'real' chemist?
The perception of a chemist varies. Some might imagine the "mad scientist" from old cartoons—a white-haired older man working with beakers in his lab—but as that cliche fades, the reality of what constitutes a chemist's ...
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.
