Controlling ion transport for a blue energy future: Research highlights the potential of nanopore membranes

Posted by in categories: energy, sustainability

Blue energy has the potential to provide a sustainable alternative to fossil fuels. In simple terms, it involves harnessing the energy produced when the ions in a salt solution move from high to low concentrations.

Simulations demonstrate potential mechanisms of intermediate-mass black hole formation in globular clusters

Posted by in category: cosmology

Joint research led by Michiko Fujii of the University of Tokyo demonstrates a possible formation mechanism of intermediate-mass black holes in globular clusters, star clusters that could contain tens of thousands or even millions of tightly packed stars.

Data-driven model generates natural human motions for virtual avatars

Posted by in category: robotics/AI

Humans can innately perform a wide range of movements, as this allows them to best tackle various tasks in their day-to-day life. Automatically reproducing these motions in virtual avatars and 3D animated human-like characters could be highly advantageous for many applications, ranging from metaverse spaces to digital entertainment, AI interfaces and robotics.

Researchers at Max Planck Institute for Intelligent Systems and ETH Zurich recently developed WANDR, a new model that can generate natural human motions for avatars. This model, to be introduced in a paper presented at the Conference on Computer Vision and Pattern Recognition (CVPR 2024) in June, unifies different data sources under a single model to attain more realistic motions in 3D humanoid characters. The paper is also posted to the arXiv preprint server.

“At a high-level, our research aims at figuring out what it takes to create able to behave like us,” Markos Diomataris, first author of the paper, told Tech Xplore. “This essentially means learning to reason about the world, how to move in it, setting goals and trying to achieve them.

Scientists achieve giant magneto-superelasticity in metal crystal

Posted by in category: futurism

Recently, a research group developed a giant magneto-superelasticity of 5% in a Ni34Co8Cu8Mn36Ga14 single crystal. This was achieved by introducing arrays of ordered dislocations to form preferentially oriented martensitic variants during the magnetically induced reverse martensitic transformation.

Violence and aggression against educators grew post-pandemic, survey says

Posted by in categories: biotech/medical, education

While threats and violence against pre-K to 12th-grade teachers and other school personnel in the United States declined during the pandemic, after the restrictions were lifted, incidents rebounded to levels equal to or exceeding those prior to the pandemic, according to research published in American Psychologist.

As a result, the percentage of teachers expressing intentions to resign or transfer rose from 49% during the pandemic to 57% afterward, the researchers found.

“Aggression and violence against educators and are major concerns that affect the well-being of school personnel and the students and families they serve. This study highlights a growing crisis in our schools that needs to be addressed nationally,” said lead author Susan Dvorak McMahon, Ph.D., of DePaul University, chair of the APA Task Force on Violence Against Educators and School Personnel. The conducted two surveys in collaboration with national education and related organizations.

New device precisely controls photon emission for more efficient portable screens

Posted by in categories: computing, mathematics, nanotechnology, quantum physics

Recently, a team of chemists, mathematicians, physicists and nano-engineers at the University of Twente in the Netherlands developed a device to control the emission of photons with unprecedented precision. This technology could lead to more efficient miniature light sources, sensitive sensors, and stable quantum bits for quantum computing.
