20:18 ScienceDaily.com Mirror-image peptides form ‘rippled sheet’ structure predicted in 1953

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.

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.

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.

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.

22:49 ScienceDaily.com Brain study on how to slow down climate change

When it comes to climate-friendly behavior, there is often a gap between what we want and what we actually do. Although most people want to see climate change slowed down, many do not behave in an appropriately sustainable way. Researchers have now used brain stimulation to demonstrate that the ability to sympathize with the future victims of climate change encourages sustainable behavior.

19:06 Phys.org Robots use fear to fight invasive fish

The invasive mosquitofish (Gambusia holbrooki) chews off the tails of freshwater fishes and tadpoles, leaving the native animals to perish while dining on other fishes' and amphibians' eggs. In a study published December 16 in the journal iScience, researchers engineered a robot to scare mosquitofish away, revealing how fear alters its behavior, physiology, fertility—and may help turn the tide against invasive species.
