A 3D mesh is a three-dimensional object representation made of different vertices and polygons. These representations can be very useful for numerous technological applications, including computer vision, virtual reality (VR) and augmented reality (AR) systems.

Researchers at Florida State University and Rutgers University have recently developed Wi-Mesh, a system that can create reliable 3D human meshes, representations of humans that can then be used by different computational models and applications. Their system was presented at the Twentieth ACM Conference on Embedded Networked Sensor Systems (ACM SenSys ‘22), a conference focusing on computer science research.

“Our research group specializes in cutting-edge wi-fi sensing research,” Professor Jie Yang at Florida State University, one of the researchers who carried out the study, told Tech Xplore. “In previous work, we have developed systems that use to sense a range of human activities and objects, including large-scale human body movements, small-scale finger movements, sleep monitoring, and daily objects. Our E-eyes and WiFinger systems were among the first to use wi-fi sensing to classify various types of daily activities and finger gestures, with a focus on predefined activities using a trained model.”

Despite decades of innovation in fabrics with high-tech thermal properties that keep marathon runners cool or alpine hikers warm, there has never been a material that changes its insulating properties in response to the environment. Until now.

University of Maryland researchers have created a that can automatically regulate the amount of heat that passes through it. When conditions are warm and moist, such as those near a sweating body, the fabric allows (heat) to pass through. When conditions become cooler and drier, the fabric reduces the heat that escapes. The development was reported in the February 8, 2019 issue of the journal Science.

The researchers created the fabric from specially engineered yarn coated with a conductive metal. Under hot, , the strands of yarn compact and activate the coating, which changes the way the fabric interacts with infrared . They refer to the action as “gating” of infrared radiation, which acts as a tunable blind to transmit or block heat.

A Quebec hospital adopts a novel use of VR to help patients with anxiety, phobias and pain.

In a newswire release today, the Fondation de l’Hôtel-Dieu d’Alma (the Alma Hospital Foundation) announced the launch of a virtual reality (VR) project aimed at improving the mental health of those experiencing increasing anxiety. The Alma Hospital is a regional health centre for the area of Lac St. Jean and the Saguenay River valley to the north of Quebec City.

Jean Lamoureux, the hospital’s Executive Director states, “The number of requests for mental-health consultations is estimated to have increased by 30 to 40 percent during the pandemic. These needs are urgent…and, thanks to the innovation of Paperplane Therapeutics and TELUS, we will transform the way health services are delivered, while having a significant positive impact on patient well-being through technology.”

Human civilization has achieved some incredible things during its short reign on this planet. Technological development over the past 5,000 years of human civilization has led our species to dominance of life on Earth and placed us on a pathway to achieving a Type I civilization.

To reach even the basic level of a “Kardashev Type 1 civilization” we must do two things:
Develop more advanced technology and share it with all responsible nations.
Make renewable energy accessible to all parts of the world.

Five hundred years ago, the Aztec civilization believed that the sun and all its power was sustained by blood from human sacrifice.
Today, we know that the sun, along with all other stars, is powered by a reaction called nuclear fusion.
Scientists and engineers have studied the Sun’s fusion process in hopes of developing a way to harness energy from fusion in machines on Earth.

What exactly is nuclear fusion, and how does it work in terms of producing electricity?
