A new nanostructured carbon design lets fuel-cell catalysts use tiny amounts of platinum while remaining remarkably stable and efficient. The breakthrough could help hydrogen fuel cells become a more practical way to power data centers, vehicles, and other energy-intensive techno

Scientists have discovered incredibly tiny plasma whirlpools swirling across the Sun’s surface, some just 20 kilometers wide. These previously invisible vortices may twist magnetic fields and help build up the energy released in small solar eruptions called nanoflares. They may a

Dinosaurs conquered the land at enormous sizes, but strangely, they almost never evolved into truly tiny animals. New research suggests that physiology alone can’t explain this missing miniature end of the dinosaur spectrum—and that early mammals may have been partly responsible.

A tiny greenish, nocturnal frog that thrives in coffee plantations has been discovered in Costa Rica's central Pacific region, where it also faces risks from agrochemicals used in farming. Mais do que repetir a manchete, o ponto aqui e entender o que essa mudanca revela e por que

People in communities thousands of miles apart have described the same strange experience after eating a mysterious mushroom: vivid visions of tiny humans moving through and interacting with the physical world around them. Known as Lilliputian hallucinations—a reference to the 6-

Nanoscience, which studies small objects, has a big problem. According to a team of scientists at the National Institute of Standards and Technology (NIST), the field confronts a pervasive data analysis error that can give misleading insights into how these tiny objects' properti
