Shipping, construction work and other human activities are altering the acoustic conditions in our planet's seas. Sound pressure is often examined to determine the effects that this underwater noise has on marine organisms. ...
Four and a half billion years ago, Earth and Mars were born in the rotating cloud of gas and dust that would eventually become our solar system. Yet exactly how the planets formed remains one of the most disputed questions ...
Manufacturing modern medicines is a multistage process, and each step introduces the opportunity for contamination, which can be both deadly and expensive. Recently, epinephrine injections, used for severe allergic reactions, ...
Most magnets have two poles: north and south, or positive and negative, in a familiar arrangement called a "dipole." But researchers are increasingly uncovering more complex forms of magnetism.
Muons are constantly being created as cosmic rays collide with molecules in Earth's upper atmosphere. With their ability to penetrate far into dense, solid materials, these cosmic muons are often used to image the insides ...
Boats passing over smooth water form a pair of diffusion wakes behind them veering off at a certain angle. Turbulence occurs along the line directly behind the boat, but the two diffusion waves are at a theoretical angle ...
Photos taken using a microscope reveal the colorful, kaleidoscope-like crystal structure of a new NASA-made material that could be used for manufacturing during future space missions. Developed at NASA's Glenn Research Center ...
From the air, Wainwright, Alaska, looks like a perfectly stable band of homes and roads between the Chukchi Sea and a vast, flat tundra. But just below the surface, the frozen ground on which this town was built contains ...
A commercial mission to boost NASA's Neil Gehrels Swift Observatory ended without raising the spacecraft's orbit, but the agency and Katalyst Space gained experience that will benefit future in-space servicing programs.
Plastic pollution is a growing threat to marine environments, with discarded waste reaching from coastlines to the deepest parts of the ocean. Now, a six-year study has revealed how quickly debris can accumulate on a beach ...
