Published Virtual reality better than video for evoking fear, spurring climate action
(via sciencedaily.com) Original source Depicting worst-case climate scenarios like expanding deserts and dying coral reefs may better motivate people to support environmental policies when delivered via virtual reality, according to a research team that studied how VR and message framing affect the impact of environmental advocacy communications. The study findings may help advocacy groups decide how best to frame and deliver their messages.
Published Opening new doors in the VR world, literally
(via sciencedaily.com) Original source Recreating the action of opening doors in the virtual world requires engineering ways in which to provide the equivalent haptic feedback and steer users away from walls in the real world. A research group has done just this; developing RedirectedDoors+, which employs door robots and rotation to create a more realistic experience.
Published Straightening teeth? AI can help
(via sciencedaily.com) Original source A new tool will help orthodontists correctly fit braces onto teeth. Using artificial intelligence and virtual patients, the tool predicts how teeth will move, so as to ensure that braces are neither too loose nor too tight.
Published Satellites for quantum communications
(via sciencedaily.com) Original source Through steady advances in the development of quantum computers and their ever-improving performance, it will be possible in the future to crack our current encryption processes. To address this challenge, researchers are developing encryption methods that will apply physical laws to prevent the interception of messages. To safeguard communications over long distances, the QUICK space mission will deploy satellites.
Published Natural history specimens have never been so accessible
(via sciencedaily.com) Original source Researchers have painstakingly taken computed topography (CT) scans of more than 13,000 individual specimens to create 3D images of more than half of all the world's animal groups, including mammals, fishes, amphibians and reptiles.
Published Angle-dependent holograms made possible by metasurfaces
(via sciencedaily.com) Original source Scientists unveil metasurface technology, allowing for angle-dependent holograms.
Published Plasma scientists develop computer programs that could reduce the cost of microchips and stimulate American manufacturing
(via sciencedaily.com) Original source Fashioned from the same element found in sand and covered by intricate patterns, microchips power smartphones, augment appliances and aid the operation of cars and airplanes. Now, scientists are developing computer simulation codes that will outperform current simulation techniques and aid the production of microchips using plasma, the electrically charged state of matter also used in fusion research. These codes could help increase the efficiency of the manufacturing process and potentially stimulate the renaissance of the chip industry in the United States.
Published Why insects navigate more efficiently than robots
(via sciencedaily.com) Original source Engineers have studied how insects navigate, for the purpose of developing energy-efficient robots.
Published Innovations in depth from focus/defocus pave the way to more capable computer vision systems
(via sciencedaily.com) Original source In an image, estimating the distance between objects and the camera by using the blur in the images as clue, also known as depth from focus/defocus, is essential in computer vision. However, model-based methods fail when texture-less surfaces are present, and learning-based methods require the same camera settings during training and testing. Now, researchers have come up with an innovative strategy for depth estimation that combines the best of both the worlds to solve these limitations, extending the applicability of depth from focus/defocus.
Published One person can supervise 'swarm' of 100 unmanned autonomous vehicles
(via sciencedaily.com) Original source Research involving has shown that a 'swarm' of more than 100 autonomous ground and aerial robots can be supervised by one person without subjecting the individual to an undue workload.
Published Swarming cicadas, stock traders, and the wisdom of the crowd
(via sciencedaily.com) Original source The springtime emergence of vast swarms of cicadas can be explained by a mathematical model of collective decision-making with similarities to models describing stock market crashes.
Published Bringing together real-world sensors and VR to improve building maintenance
(via sciencedaily.com) Original source A new system that brings together real-world sensing and virtual reality would make it easier for building maintenance personnel to identify and fix issues in commercial buildings that are in operation.
Published 'Smart glove' can boost hand mobility of stroke patients
(via sciencedaily.com) Original source This month, a group of stroke survivors in British Columbia will test a new technology designed to aid their recovery, and ultimately restore use of their limbs and hands. Participants will wear a new groundbreaking 'smart glove' capable of tracking their hand and finger movements during rehabilitation exercises.
