Scientists from the University of Bristol have developed a soap, composed of iron rich salts dissolved in water, that responds to a magnetic field when placed in solution. The soap's magnetic properties were proved with neutrons ...

(Phys.org)—Scientists have demonstrated that pinwheel-shaped microgears floating on a liquid surface can rotate at speeds of up to 300 r.p.m. when illuminated by an ordinary LED. This light-driven motion, which arises because ...
Scientists have solved the riddle behind one of the most recognisable, and annoying, household sounds: the dripping tap. And crucially, they have also identified a simple solution to stop it, which most of us already have ...

A recent feature cover photo on Science portrayed a bubble in mid-collapse, based on a study conducted by Alexandros T. Oratis et al. The research team in mechanical engineering, mathematics and aerospace engineering at Boston ...
Sometimes in shallow water, a type of wave can form that is much more stable than ordinary waves. Called solitons, these phenomena emerge as solitary waves and can travel long distances while maintaining their shape and speed, ...
A decade ago a new idea was brought into the general scientific community—shedding water from condensers was more efficient by using surface tension to make microscopic water droplets "jump" off the surface. The idea took ...
