Scientists Are Getting Better and Better at Levitating Objects With Sound Waves

Researchers have come up with a new and improved way to levitate objects using sound waves alone, an impressive feat of mixed-reality technology that could pave the way for some seriously futuristic hologram-like displays.

As seen in a new video, the researchers were able to levitate individual polystyrene beads and water particles inside a special enclosure, making them move in three dimensions by adjusting the output of hundreds of small speakers, set up in a grid.

In one demonstration, they were even able to float a tiny piece of fabric in midair, on which they projected a movie of a leaping rabbit.

Silence for Thought: Special Interneuron Networks in the Human Brain

Summary: Human cortical networks have evolved a novel neural network that relies on abundant connections between inhibitory interneurons.

The analysis of the human brain is a central goal of neuroscience. However, for methodological reasons, research has largely focused on model organisms, in particular the mouse.

Robotic Armband Shows Promise for Advanced Dexterity

AZoRobotics speaks with Dr. Erik Enegberg from Florida Atlantic University about his research into a wearable soft robotic armband. This could be a life-changing device for prosthetic hands users who have long-desired advances in dexterity.

Typing on a keyboard, pressing buttons on a remote control, or braiding a child’s hair has remained elusive for prosthetic hand users. How does the loss of tactile sensations impact limb-absent people’s lives?

Losing the sensation of touch has a profound impact on people’s lives. Some of the things that may seem simple and a part of everyday life, such as stroking the fur of a pet or the skin of a loved one, are a meaningful and fundamental way to connect with those around us for others. For example, a patient with a bilateral amputation has previously expressed concerns that he might hurt his granddaughter by accidentally squeezing her hand too tightly as he has lost tactile sensation.

Beating NASA, China Set To Become 1st Country To Get Martian Sample Back On Earth — Chinese Expert

The space race has been silently intensifying with the geopolitical battle raging on the ground. With the United States having delayed its Mars mission to bring back samples to Earth, China could beat its rival in achieving that milestone. 4th Failure? NASA’s Artemis Rocket ‘Leaks’ During Pre-Launch Test As US Aims To Land Humans On […].
