Physicists create time-reversed optical waves

Optics researchers from The University of Queensland and Nokia Bell Labs in the US have developed a new technique to demonstrate the time reversal of optical waves, which could transform the fields of advanced biomedical ...

Shining a light on the mechanics of embryo development

In 1922, French physicist Léon Brillouin predicted an interesting phenomenon—when light is shone on a material, it interacts with the naturally occurring thermal vibrations within it, exchanging some energy in the process. ...

Understanding rogue waves of the Eastern Mediterranean Sea

The eastern Mediterranean Sea, a large basin surrounded by ancient cultural sites, is also a climatology hot spot. However, the region has received comparatively little attention when it comes to understanding the extreme ...

Low-cost disease diagnosis by mapping heart sounds

Aortic valve stenosis occurs when the aortic valve narrows, constricting blood flow from the heart through the artery and to the entire body. In severe cases, it can lead to heart failure. Identifying the condition can be ...

Halting a wave in its tracks

Topological ideas have recently taken the center stage of modern electromagnetics. Typical topological photonic systems are based on nonreciprocal materials, a class of materials that enables asymmetric light–matter interactions. ...
