Improving the manipulation of microparticles by sound

A simple but accurate theory of how sound interacts with small particles has been developed by theoretical physicists at RIKEN. This advance will help to improve the manipulation of microparticles by sound.

Designing lasers based on quantum physics

A five-country research team coordinated by Germán J. de Valcárcel Gonzalvo, Professor of Optics at the University of Valencia, has developed a new theory —the coherent master equation— that describes the behavior of ...

New model shows how crop rotation helps combat plant pests

A new computational model shows how different patterns of crop rotation—planting different crops at different times in the same field—can impact long-term yield when the crops are threatened by plant pathogens. Maria ...

A new mathematical model predicts a knot's stability

In sailing, rock climbing, construction, and any activity requiring the securing of ropes, certain knots are known to be stronger than others. Any seasoned sailor knows, for instance, that one type of knot will secure a sheet ...
