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 / 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 / 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 / Universal surface-growth law confirmed in two dimensions after 40 years
Crystals, bacterial colonies, flame fronts: the growth of surfaces was first described in the 1980s by the Kardar–Parisi–Zhang equation. Since then, it has been regarded as a fundamental model in physics, with implications ...
Phys.org / SoCal's hybrid bees outsmart Varroa mites before they even hatch
Southern California is home to a flying black-and-yellow treasure. While commercial honeybee hives nationwide are collapsing under attack from deadly parasites, a unique hybrid bee found only in this part of the state has ...
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 / 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 / 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 / Rare Roman paint 'recipe' uncovered in Cartagena murals makes smart use of costly cinnabar
Roman painters commissioned at the end of the 1st century to decorate the walls of the Domus of Salvius in present-day Cartagena could hardly have imagined that their technical expertise would still attract attention twenty ...
