Self-oscillations (red and blue) guide sound waves (green, orange, purple) in only one direction through the circulator. (Xin Zou)Imagine three people arranged in a circle, where each can only hear one other directly. Scientists have created a device that directs sound waves in just this way, allowing them to travel in a single direction only.Developed...

The ultrasensitive robot 'finger' can perform routine physical examsUSTC/Hongbo WangResearchers have created an ultrasensitive robotic ‘finger’ that mimics human touch, capable of safely conducting routine physical exams similar to those performed by doctors. They believe this 'robodoctor' could soon appear in medical clinics.Doctors use their fingers as diagnostic tools to gather various insights about...
The hole-digging, seed-bomb-depositing, Plantolin pangolin-inspired robotUniversity of SurreyForaging pangolins naturally dig in the ground, so why not have them plant trees at the same time? Training them to do so would be quite challenging, which is why a high school student from California named Dorothy created a pangolin-inspired robot to handle the digging and...
