High-energy particles in radiation belts can look as if they are spreading randomly even when their underlying motion remains predictable. A moving spacecraft can lose sight of fine particle ...

Landslides are one striking example of erosion. When the bonds that hold particles of dirt and rock together are overwhelmed by a force — often in the form of water — sufficient to pull the rock and ...

Scientists have observed a unique particle that moves easily one way, yet resists at 90 degrees. These semi-Dirac fermions were observed using their energy signature in a topological metal. Particles ...

If you've ever watched a flock of birds move in perfect unison or seen ripples travel across a pond, you've witnessed nature's remarkable ability to coordinate motion. Recently, a team of scientists ...

Landslides are one striking example of erosion. When the bonds that hold particles of dirt and rock together are overwhelmed by a force—often in the form of water—sufficient to pull the rock and soil ...

In the supplemental material the experimental setup is shown (see top image), which is designed to make the individual iron-coated polymer particles rotate. The particles are called Janus particles ...

Science is built on making assumptions and then testing those assumptions, and sometimes the testing part has a bit of a ...

Hundreds of microscopic particles suspended in liquid can work together as a computer, using their collective motion to ...

Scientists didn’t understand why independently oscillating microscopic particles suddenly begin moving in perfect sync when grouped together. Researchers showed that fluid-driven hydrodynamic ...

It is commonly assumed that tiny particles just go with the flow as they make their way through soil, biological tissue, and other complex materials. But a team of Yale researchers led by Professor ...
