Phys.org / Yellowstone's magma plumbing mainly shaped by tectonic forces—not deep mantle plume
A lot of research goes into determining how to best predict the next eruption of the Yellowstone supervolcano. Part of this involves pinning down how the magma migration system functions and evolves over time. The exact mechanism ...
Phys.org / Archaeological survey at Gnith reveals new details about pearl millet's westward expansion
A study published in Azania: Archaeological Research in Africa sheds new light on the westward spread of pearl millet (Pennisetum glaucum) agriculture in prehistoric West Africa. A recent survey documented its earliest known ...
Phys.org / Dual-frequency Paul trap shows potential for synthesizing antihydrogen outside of CERN
A new type of radiofrequency trap can capture particles with extremely different requirements and could theoretically hold both types of particles at the same time. Researchers in the group of Professor Dmitry Budker from ...
Phys.org / Yellowstone's magma source may be closer than thought, reshaping hazard models
Supereruptions are extremely large volcanic eruptions that eject more than 1,000 cubic kilometers of magma, rock and ash. They are among the most hazardous geological events on Earth and have profound impacts on the environment, ...
Phys.org / Peculiar core-collapse supernova breaks the mold with a long, dim plateau
Astronomers from the Chinese Academy of Sciences (CAS) have employed the Lijiang 2.4-m telescope to perform optical photometric and spectroscopic observations of a core-collapse Type IIP supernova designated SN 2024abfl. ...
Phys.org / Back-to-back Amazon droughts trigger record forest stress
Two back-to-back droughts in 2023 and 2024 caused the most severe decline in forest moisture and biomass (the total mass of living vegetation such as leaves, trunks and branches) in the Amazon since 1992, according to a study ...
Phys.org / From teeth to thorns: Coincidences shape the universal form of nature's pointed tips
We thought it was evolution, but an experiment with pencils shows that tips like teeth and thorns may owe their rounded shape to mechanical wear. Most of us have been stung by a bee, bitten by an animal, or scratched by a ...
Phys.org / Search for dark matter intensifies as leading detector reaches milestone
Deep underground in a Canadian mine, a refrigerator nearly 1,000 times colder than outer space has just reached its target temperature—a milestone that brings scientists one step closer to potentially detecting dark matter, ...
Phys.org / SNIPE bacterial defense system shreds phage DNA before infection can begin
What if the Trojan horse had been pulled to pieces, revealing the ruse and fending off the invasion, just as it entered the gates of Troy? That's an apt description of a newly characterized bacterial defense system that chops ...
Phys.org / Parachutes: A vital part of Artemis II's trip home
As the Orion spacecraft hurtles home, friction caused by reentry into Earth's atmosphere will drastically decrease its speed from a potential 25,000 miles per hour (40,000 kilometers per hour).
Phys.org / Subaru Telescope sheds light on Jupiter Trojan asteroids' color mystery
Observations conducted with the Subaru Telescope and its first-generation wide-field camera, Suprime-Cam, have revealed new insights into the relationship between the color and size of Jupiter Trojan asteroids.
Phys.org / Scientists discover f-block metals yield new oxygen-binding chemistry
Iron and oxygen bind together throughout the body. Most famously, iron binds dioxygen, or two oxygens paired with each other, in hemoglobin that transports oxygen through blood. But iron-oxo compounds, as they're called, ...
