By mixing a small peptide with equal amounts of its mirror image, scientists have created an unusual protein structure known as a 'rippled beta sheet' and obtained images of it using x-ray crystallography. The rippled sheet is a distinctive variation on the pleated beta sheet, which is a well-known structural motif found in thousands of proteins, including important disease-related proteins. Linus Pauling and Robert Corey described the rippled beta sheet in 1953, two years after introducing the concept of the pleated beta sheet.

The human health is suffering from effluent containing heavy metal ions (such as Cr(VI)) and organic dyes (such as rhodamine B). Among numerous strategies to remove pollutants from water, photocatalysis has attracted extensive attention due to its low energy consumption, simple operation and environmental friendliness. Bimetallic sulfides are apt to form the heterointerfaces which is able to modify the surface properties of particles and enhance the stability and the photocatalytic performances. h-BN has been proved to be a prospective support for different composites because of its diversified sheet structure, higher surface area, chemical resistance, can effectively increase the accessible superficial area of loaded catalysts and supply abundant active sites.

A novel approach to testing for the presence of the virus that causes COVID-19 may lead to tests that are faster, less expensive, and potentially less prone to erroneous results than existing detection methods. Though the work, based on quantum effects, is still theoretical, these detectors could potentially be adapted to detect virtually any virus, the researchers say.

In this image, the NASA/ESA Hubble Space Telescope captures a side-on view of NGC 3568, a barred spiral galaxy roughly 57 million light-years from the Milky Way in the constellation Centaurus. In 2014 the light from a supernova explosion in NGC 3568 reached Earth—a sudden flare of light caused by the titanic explosion accompanying the death of a massive star. While most astronomical discoveries are the work of teams of professional astronomers, this supernova was discovered by amateur astronomers who are part of the Backyard Observatory Supernova Search in New Zealand. Dedicated amateur astronomers often make intriguing discoveries—particularly of fleeting astronomical phenomena such as supernovae and comets.

However, gaps remain in our understanding of the mechanisms that couple hole spins to electric fields. Here, the authors investigate the effect of unintentional strain on the spin state of a single hole confined in a metal-oxide-semiconductor (MOS) quantum dot. Results show that the metal electrodes produce a nonuniform strain profile, resulting in nanometer-scale variations in the heavy-hole–light-hole splitting. Therefore, local electric fields can

Mesocrystals are a class of solids formed by the regular arrangement of nanocrystals, which are tiny nanoparticles that have unique properties due to their small size. In mesocrystals, these take on a highly organized, superordinate form in a densely packed grid. A German-Swiss research team led by Professor Helmut Cölfen, a chemist from Konstanz, has now succeeded in synthesizing particularly complex mesocrystals with largely unknown chemical and physical properties and in shedding light on their structure.

The working memory is the brain's ability to process information for a short period of time in a retrievable state.

The scientists found that birds and monkeys—despite their different brain architecture—share the same central mechanisms and limits of working memory.

While they have long been a subject of academic study, social virtual reality (SVR) systems are now attracting increasingly large audiences on current consumer virtual reality systems. The design space of SVR systems is very large, and relatively little is known about how these systems should be constructed in order to be usable and efficient. In this paper we present Ubiq, a toolkit that focuses on facilitating the construction of SVR systems. We argue for the design strategy of Ubiq and its scope. Ubiq is built on the Unity platform. It provides core functionality of many SVR systems such as connection management, voice, avatars, etc. However, its design remains easy to extend. We demonstrate examples built on Ubiq and how it has been successfully used in classroom teaching. Ubiq is open source (Apache License) and thus enables several use cases that commercial systems cannot.
