Low-energy solar particles from beyond Earth found near the Sun
by
•Scientists have identified low-energy particles lurking near the Sun that likely originated from solar wind interactions well beyond Earth orbit. NASA’s Parker Solar Probe is venturing closer to the Sun …read more Source:: Science
Micromotors push around single cells and particles
by
•A new type of micromotor — powered by ultrasound and steered by magnets — can move around individual cells and microscopic particles in crowded environments without damaging them. In one …read more Source:: Science
Microplastic drifting down with the snow
by
•Over the past several years, microplastic particles have repeatedly been detected in sea-water, drinking water, and even in animals. But these minute particles are also transported by the atmosphere and …read more Source:: Science
Schrödinger’s cat with 20 qubits
by
•Dead or alive, left-spinning or right-spinning — in the quantum world particles such as the famous analogy of Schrödinger’s cat can be all these things at the same time. An …read more Source:: Science
Scientists discover what powers celestial phenomenon STEVE
by
•The celestial phenomenon known as STEVE is likely caused by a combination of heating of charged particles in the atmosphere and energetic electrons like those that power the aurora, according …read more Source:: Science
Defying the laws of physics? Engineers demonstrate bubbles of sand
by
•A recent discovery explains a new family of gravitational instabilities in granular particles of different densities that are driven by a gas-channeling mechanism not seen in fluids. The team observed …read more Source:: Science
Robotic ‘gray goo’
by
•Researchers have demonstrated for the first time a way to make a robot composed of many loosely coupled components, or ‘particles.’ Unlike swarm or modular robots, each component is simple, …read more Source:: Science
Scientists levitate particles with sound to find out how they cluster together
by
•Scientists have used sound waves to levitate particles, revealing new insights about how materials cluster together in the absence of gravity — principles which underlie everything from how molecules assemble …read more Source:: Science
Ingredients for water could be made on surface of moon, a chemical factory
by
•When a stream of charged particles known as the solar wind careens onto the moon’s surface at 450 kilometers per second (or nearly 1 million miles per hour), they enrich …read more Source:: Science
