Commerically-viable optomechanical device enables more sensitive motion detection

Researchers have developed a new type of optomechanical device that uses a microscopic silicon disk to confine optical and mechanical waves. Described in Optics Express, the new device is customisable and compatible with commercial manufacturing processes, making it a practical solution for improving sensors that detect force and movement


Researchers measure vortex breakdown for first time with parrot flying through laser sheet

A study involving a parrot flying through a laser sheet has led to researchers demonstrating, for the first time, that the strong vortices left behind as animals fly are broken down as the bird flaps its wings. The conclusions of the research challenge three well-accepted theories for calculating lift.
