Quantum Leap for Speed Limit Bounds
Source: Rice University
Nature’s speed limits aren’t posted on road signs, but Rice University physicists have discovered a new way to deduce them that is better — infinitely better, in some cases — than previous methods. In a study published today in the American Physical Society journal PRX Quantum, Hazzard and Rice graduate student Zhiyuan Wang describe a new method for calculating the upper bound of speed limits in quantum matter.

Future wireless networks of the 6th generation (6G) will consist of a multitude of small radio cells that need to be connected by broadband communication links. In this context, wireless transmission at THz frequencies represents a particularly attractive and flexible solution. Researchers at Karlsruhe Institute of Technology (KIT) have now developed a novel concept for low-cost terahertz receivers.

New Glove-Like Device Mimics Sense of Touch
Source: University of New South Wales What if you could touch a loved one during a video call – particularly in today’s social distancing era of COVID-19 – or pick up and handle a virtual tool in a video game? UNSW engineers have invented a soft wearable device which simulates the sense of touch and has wide potential for medical, industrial and entertainment applications.

Experiments Reveal Why Human-Like Robots Elicit Uncanny Feelings
Source: Emory Health Sciences Androids, or robots with humanlike features, are often more appealing to people than those that resemble machines — but only up to a certain point. Many people experience an uneasy feeling in response to robots that are nearly lifelike, and yet somehow not quite “right.” The feeling of affinity can plunge into one of repulsion as a robot’s human likeness increases, a zone known as “the uncanny valley.”
