Nanosheet-based electronics could be one drop away

Scientists at Japan's Nagoya University and the National Institute for Materials Science have found that a simple one-drop approach is cheaper and faster for tiling functional nanosheets together in a single layer. If the process, described in the journal ACS Nano, can be scaled up, it could advance development of next-generation oxide electronics.

Using the SYK model to examine the fast-charging process of quantum batteries

The Sachdev-Ye-Kitaev (SYK) model, an exactly solvable model devised by Subir Sachdev and Jinwu Ye, has recently proved useful for understanding the characteristics of different types of matter. As it describes quantum matter without quasiparticles and is simultaneously a holographic version of a quantum black hole, it has so far been adopted by both condensed matter and high-energy physicists.

A model that can create unique Chinese calligraphy art

Over the past few years, computer scientists have developed increasingly advanced and sophisticated artificial intelligence (AI) tools, which can tackle a wide variety of tasks. This includes generative adversarial networks (GANs), machine-learning models that can learn to generate new data, including text, audio files or images. Some of these models can also be tailored for creative purposes, for instance, to create unique drawings, songs or poems.

Entangling electrons with heat

A joint group of scientists from Finland, Russia, China and the U.S. has demonstrated that temperature difference can be used to entangle pairs of electrons in superconducting structures. The experimental discovery, published in Nature Communications, promises powerful applications in quantum devices, bringing us one step closer to applications of the second quantum revolution.

High-speed atomic force microscopy visualizes cell protein factories

Ribosomes are the complexes of ribonucleoproteins at the heart of protein synthesis in cells. However, in the absence of conclusive evidence, how these complexes operate has been open to debate. Now, Hirotatsu Imai and Noriyuki Kodera at Kanazawa University, alongside Toshio Uchiumi at Niigata University in Japan, show visualizations of the structural dynamics and factor pooling that take place at ribosome stalk proteins as they build new proteins.

Uber and Lyft increase average vehicle ownership in urban areas

The landscape of individual transportation has changed drastically since the rise of rideshare apps like Uber and Lyft. Where before, getting from A to B required you to either take public transportation, locate a taxi, or own your own private vehicle, being able to call yourself a ride with the push of a button has made going through life without owning a car much more feasible—and in some cases, even desirable.

New analysis highlights importance of groundwater discharge into oceans

An invisible flow of groundwater seeps into the ocean along coastlines all over the world. Scientists have tended to disregard its contributions to ocean chemistry, focusing on the far greater volumes of water and dissolved material entering the sea from rivers and streams, but a new study finds groundwater discharge plays a more significant role than had been thought.

Engineers find antioxidants improve nanoscale visualization of polymers

Reactive molecules, such as free radicals, can be produced in the body after exposure to certain environments or substances and go on to cause cell damage. Antioxidants can minimize this damage by interacting with the radicals before they affect cells.

Bats with white-nose syndrome prefer suboptimal habitats despite the consequences

Since 2006, a fungal disease called white-nose syndrome has caused sharp declines in bat populations across the eastern United States. The fungus that causes the disease, Pseudogymnoascus destructans, thrives in subterranean habitats where bats hibernate over the winter months.
