A genome-editing strategy developed at Rice University can correct dozens of errors at the same time with high precision and efficiency, a possible breakthrough for those who suffer from diseases caused by a combination of mutations.

All-inorganic lead-free luminescent metal halide nanocrystals (NCs) are very important in optoelectronics, but their applications are limited by the low photoluminescence (PL) efficiency. It is an effective approach via ns2-metal ions doping for tailoring the optical properties of metal halide NCs and expanding their applications.

Ever since the discovery of the quantum Hall effect (Nobel Prize 1985), symmetry has been the guiding principle in the search for topological materials. Now an international team of researchers from Germany, Switzerland, and the U.S. has introduced an alternative guiding principle, "quasi-symmetry," which leads to the discovery of a new type of topological material with great potential for applications in spintronics and quantum technologies. This work has been published in Nature Physics.

In order to achieve a fusion power plant, it is necessary to stably confine a plasma of more than 100 million degrees Celsius in a magnetic field and maintain it for a long time. A research group led by Assistant Professor Naoki Kenmochi, Professor Katsumi Ida, and Associate Professor Tokihiko Tokuzawa of the National Institute for Fusion Science (NIFS), National Institutes of Natural Sciences (NINS), Japan, using measuring instruments developed independently and with the cooperation of Professor Daniel J. den Hartog of the University of Wisconsin, USA, discovered for the first time that turbulence moves faster than heat when heat escapes in plasmas in the Large Helical Device (LHD). One characteristic of this turbulence makes it possible to predict changes in plasma temperature, and it is expected that observation of turbulence will lead to the development of a method for real-time control of plasma temperature in the future.

It's difficult to ask, but how many fatalities should Australia accept from COVID in 2022?

In recent years, physicists have carried out extensive studies focusing on quantum technology and quantum many-body systems. Two out-of-equilibrium dynamical processes that have attracted particular attention in this field are quantum thermalization and information scrambling.

Companies should introduce ways of uncovering informal hidden cultures to create more inclusive workplaces, a social mobility expert has told parliamentarians.

Metamaterials—artificial media with tailored subwavelength structures—have now encompassed a broad range of novel properties that are unavailable in nature. This field of research has stretched across different wave platforms, leading to the discovery and demonstration of a wealth of exotic wave phenomena. Most recently, metamaterial concepts have been extended to the temporal domain, paving the way to completely new concepts for wave control, such as nonreciprocal propagation, time-reversal, new forms of optical gain and drag.

A new study provides a framework to boost crop growth by incorporating a strategy adopted from a fast-growing species of green algae. The algae, known as Chlamydomonas reinhardtii, contain an organelle called the pyrenoid that speeds up the conversion of carbon, which the algae absorb from the air, into a form that the organisms can use for growth. In a study published May 19, 2022 in the journal Nature Plants, researchers at Princeton University and Northwestern University used molecular modeling to identify the features of the pyrenoid that are most critical for enhancing carbon fixation, and then mapped how this functionality could be engineered into crop plants.

Based on an evaluation of over 500 academic articles, an international research team has traced the application of greening concepts in the context of Swedish planning and particularly in the Stockholm metropolitan region. The researchers, who include Professor Christian Albert's research lab Planning Metropolitan Landscapes at Ruhr-Universität Bochum (RUB), have drawn up recommendations for urban planning. One of their recommendations is to use scientific expertise and to focus on narratives that emphasize the importance of urban green spaces for human well-being. They argue that this is a way to gain momentum for ideas and action. The researchers published their findings in the journal Urban Forestry & Urban Greening on 26 April 2022.
