Phys.org / Mystery of massive aurora in Arctic skies in December 2022 solved by astronomers
A small team of astronomers affiliated with several institutions in Japan, working with a pair of colleagues in the U.S., has solved the mystery of the unusually smooth aurora that appeared in the Arctic sky in December of ...
Phys.org / New organoid culture method can verify human toxicity of nanomaterials
The Korea Research Institute of Standards and Science (KRISS) has developed the world's first organoid culture method capable of accurately assessing human toxicity of nanomaterials. Overcoming the limitations of the conventional ...
Phys.org / Geologists expect Chang'e-6 lunar surface samples to contain volcanic rock and impact ejecta
On June 25, China's Chang'e-6 (CE-6) lunar probe is set to return to Earth, carrying the first surface samples collected from the farside of the moon. In anticipation of this historic event, scientists from the Institute ...
Phys.org / Hydrothermal vents on seafloors of 'ocean worlds' could support life, new study says
We've all seen the surreal footage in nature documentaries showing hydrothermal vents on the frigid ocean floor—bellowing black plumes of super-hot water—and the life forms that cling to them. Now, a new study by UC Santa ...
Phys.org / New mathematical proof helps to solve equations with random components
Whether it's physical phenomena, share prices or climate models—many dynamic processes in our world can be described mathematically with the aid of partial differential equations. Thanks to stochastics—an area of mathematics ...
Phys.org / Secrets of salt drop stains unveiled: New research decodes chemical composition from simple photos
Imagine zooming in on a dried drop of salt solution—each pattern a unique masterpiece, reminiscent of abstract art, yet no larger than the size of a penny.
Phys.org / Space radiation can damage satellites—next-generation material could self-heal when exposed to cosmic rays
The space environment is harsh and full of extreme radiation. Scientists designing spacecraft and satellites need materials that can withstand these conditions.
Phys.org / Researchers develop tuneable anti-counterfeiting material
Counterfeiters are becoming increasingly more sophisticated in forging everything from diplomas and currency to medications and artwork. While protective measures such as luminescent markings (which glow under ultraviolet ...
Phys.org / AI-based approach matches protein interaction partners
Proteins are the building blocks of life, involved in virtually every biological process. Understanding how proteins interact with each other is crucial for deciphering the complexities of cellular functions, and has significant ...
Phys.org / Rare Sāmoan discovery offers clues to origins of inequality
The discovery of ancient rock walls and high mounds and ditches in dense jungle in the Falefa Valley on 'Upolu Island in Sāmoa holds valuable clues to the origins of ancestral land and social hierarchy in Polynesian society, ...
Phys.org / Researchers develop RNA-targeting technology for precisely manipulating parts of human genes
Researchers at the University of Toronto have harnessed a bacterial immune defense system, known as CRISPR, to efficiently and precisely control the process of RNA splicing. The technology opens the door to new applications, ...
