From special pens to earwax evaluations, a plethora of emerging diagnostics could one day be a major boon for people with the debilitating disease.
Hair, nails, and horns, all made up of keratin, are some of the hardest and most resilient structures in animals. Inside zebrafish cells, keratin plays a distinct role, giving them the strength they need to move together as a coherent tissue while modulating the driving forces
Generative AI (GenAI) is a type of artificial intelligence that creates new content—like text, images, or ideas—by learning patterns from existing data. GenAI, particularly through large language models (LLMs) such as ChatGPT and DeepSeek, is rapidly becoming part of everyday
Black holes are regions in space where gravity is so strong that nothing, even light, can escape. Einstein's theory of general relativity breaks down inside black holes, either by the presence of a so-called "curvature singularity" or "Cauchy horizon."
This year’s expected El Niño could hamper hurricanes in the Atlantic but boost them in the central and eastern Pacific
Digital culture is reshaping people's experiences of fear, curiosity and belonging, according to new findings from Lancaster University. Researchers have explored why online environments like the "Backrooms"—mysterious empty spaces resembling uncharted office blocks, basements
A new study shows that apparently erratic or "sloppy" behavior in strategic situations is not necessarily a mistake. Under certain conditions, being less sensitive to one's own gains can become a long-term advantage.
Strong relationships between overseas staff and local colleagues are central to the success of global assignments, according to a new study by the University of Portsmouth and Reutlingen University which aims to advise multinational companies on how they can avoid costly
