Despite years of hype, virtual reality headsets have yet to topple TV or computer screens as the go-to devices for video viewing. One reason: VR can make users feel sick. Nausea and eye strain can result because VR creates an illusion of 3D viewing although the user is in fact staring at a fixed-distance 2D display. The solution for better 3D visualization could lie in a 60-year-old technology remade for the digital world: holograms. ....

Robots can use eye contact to draw out reluctant participants in groups

Researchers at KTH Royal Institute of Technology published results of experiments in which robots led a Swedish word game with individuals whose proficiency in the Nordic language was varied. They found that by redirecting its gaze to less proficient players, a robot can elicit involvement from even the most reluctant participants. ....

Energy-efficient light-emitting diodes (LEDs) have been used in our everyday life for many decades. But the quest for better LEDs, offering both lower costs and brighter colours, has recently drawn scientists to a material called perovskite. A recent joint-research project co-led by the scientist from
City University of Hong Kong (CityU) has now developed a 2D perovskite material for the most efficient LEDs.
From household lighting to mobile phone displays, from pinpoint lighting needed for endoscopy procedures to light source to grow vegetables in Space, LEDs are everywhere. Yet current high-quality LEDs still need to be processed at high temperatures and using elaborated deposition technologies which make their production cost expensive. ....

Not-for-profit publisher makes big move toward open access science

E-Mail
Canadian Science Publishing (CSP) a not-for-profit publisher of peer-reviewed STEM journals is excited to announce a new transformative open access publishing agreement with the University of California (UC) that will offer unlimited open access publication for UC researchers publishing with its journals.
The transformative agreement is the first of its kind for a Canadian journal publisher and a pivotal first step for CSP and its international authors and readers. The Ottawa-based not-for-profit is exploring how to shift from subscription-based business models to models that make it easier and more affordable for researchers to publish their work open access.
Access to peer-reviewed science has never been more important. As a not-for-profit navigating the switch from subscription to open access, we see transformative models as a sustainable way to open up the scientific literature, says Suzanne Kettley, Chief Executive Officer at CSP. ....

Flexible and adaptive microelectronics is considered an innovation driver for new and more effective biomedical applications. These include, for example, the treatment of damaged nerve bundles, chronic pain, or the control of artificial limbs. For this to work, close contact between electronics and neural tissue is essential for effective electrical and mechanical coupling. In addition, potential applications arise from the production of tiny and flexible surgical tools. ....
