A team of researchers lead by the University of Tsukuba have created a new theoretical model to understand the spread of vibrations through disordered materials, such as glass. They found that as the degree of disorder increased, sound waves traveled less and less like ballistic particles, and instead began diffusing incoherently. This work may lead to new heat- and … [Read more...] about Spreading the sound

In groundbreaking materials research, a team led by University of Minnesota Professor K. Andre Mkhoyan has made a discovery that blends the best of two sought-after qualities for touchscreens and smart windows -- transparency and conductivity. The researchers are the first to observe metallic lines in a perovskite crystal. Perovskites abound in the Earth's center, and barium … [Read more...] about Conductive nature in crystal structures revealed at magnification of 10 million times

It's not just to hide clutter anymore -- add "saving the planet" to the reasons you leave the camera off during your next virtual meeting. A new study says that despite a record drop in global carbon emissions in 2020, a pandemic-driven shift to remote work and more at-home entertainment still presents significant environmental impact due to how internet data is stored and … [Read more...] about Turn off that camera during virtual meetings, environmental study says: Simple tips to go green with your internet use during a pandemic

Researchers from the University of Cambridge, the University of Milan and Google Research have used machine learning techniques to predict how proteins, particularly those implicated in neurological diseases, completely change their shapes in a matter of microseconds. They found that when amyloid beta, a key protein implicated in Alzheimer's disease, adopts a highly disordered … [Read more...] about Following the hops of disordered proteins could lead to future treatments of Alzheimer’s disease

As the story goes, the Greek mathematician and tinkerer Archimedes came across an invention while traveling through ancient Egypt that would later bear his name. It was a machine consisting of a screw housed inside a hollow tube that trapped and drew water upon rotation. Now, researchers led by Stanford University physicist Benjamin Lev have developed a quantum version of … [Read more...] about New state of matter in one-dimensional quantum gas

Scientists tame photon-magnon interaction. Working with theorists in the University of Chicago's Pritzker School of Molecular Engineering, researchers in the U.S. Department of Energy's (DOE) Argonne National Laboratory have achieved a scientific control that is a first of its kind. They demonstrated a novel approach that allows real-time control of the interactions between … [Read more...] about Pivotal discovery in quantum and classical information processing

Physicists at Washington University in St. Louis have discovered how to locally add electrical charge to an atomically thin graphene device by layering flakes of another thin material, alpha-RuCl3, on top of it. A paper published in the journal Nano Letters describes the charge transfer process in detail. Gaining control of the flow of electrical current through atomically thin … [Read more...] about New way to control electrical charge in 2D materials: Put a flake on it

Compared to standard machine learning models, deep learning models are largely superior at discerning patterns and discriminative features in brain imaging, despite being more complex in their architecture, according to a new study in Nature Communications led by Georgia State University. Advanced biomedical technologies such as structural and functional magnetic resonance … [Read more...] about Deep learning outperforms standard machine learning in biomedical research applications

There are things in life that can be predicted reasonably well. The tides rise and fall. The moon waxes and wanes. A billiard ball bounces around a table according to orderly geometry. And then there are things that defy easy prediction: The hurricane that changes direction without warning. The splashing of water in a fountain. The graceful disorder of branches growing from a … [Read more...] about Studying chaos with one of the world’s fastest cameras

Scientists at the University of California, Irvine have developed a new deep-learning framework that predicts gene regulation at the single-cell level. Deep learning, a family of machine-learning methods based on artificial neural networks, has revolutionized applications such as image interpretation, natural language processing and autonomous driving. In a study published … [Read more...] about Researchers use deep learning to identify gene regulation at single-cell level: Novel ability could further understanding and treatment of diseases such as cancer
