Human-made microbeads don’t always go with the flow. Under certain conditions, the artificial particles can align themselves with a fluid’s flow and then swim upstream, researchers report May 1 in ...
But such measurements are notoriously challenging: the instruments used are themselves governed by quantum laws, and their interaction with particles can alter the very properties they are meant to ...
What if the Higgs boson found in 2012 is not alone but is the only sibling we have encountered so far? Scientists at CERN discovered the particle that year, and it was a major discovery because it ...
Atmospheric and climate scientists show that biological particles may induce rain events that could contribute to flooding and snowstorms, owing to their ability to precipitate ice formation in clouds ...
A study shows that similarly charged particles can sometimes attract, rather than repel. The team found that like-charged particles suspended in liquids can attract one another at long-range, ...
Scientists discovered microscopic magnetic particles in most bee species examined. This finding suggests a widespread ...
While science has a solid grasp on calculating drag and resistance on microscopic spherical objects, particles like dust, microplastics, and viruses are rarely spherical. A new study re-analyzes a ...
In new research, scientists find that flocks of birds may become ordered after a disordered start. The way flocks and other “collective motions” form has eluded scientists for a long time.
