Nanomechanical resonators are miniature vibrating structures on chips that oscillate at frequencies ranging from a few kilohertz to gigahertz. They are used as ultrasensitive detectors of mass and force, temperature and pressure, and as components in radio frequency filters and o

New research reveals the unusual shape, size and pattern of the dermal denticles that cover basking sharks—thought to be unique to this species. Researchers propose that the shape and arrangement of the skin's scales protect the skin while also allowing for the stretchiness requi

Usually there's safety in numbers, but it doesn't always work that way. Fin whales (Balaenoptera physalus) filter-feed on immense shoals of krill, engulfing colossal mouthfuls of water containing up to 144 kg of the crustaceans. But then the mighty creatures expel the water by sq

K2-18b is one of the most promising worlds for the search for extraterrestrial life, so astronomers conducted an unusually powerful radio survey using both the VLA and MeerKAT telescopes. Advanced software analyzed millions of signals, filtering out Earth-based interference and o
