Published Unlocking the secrets of quasicrystal magnetism: Revealing a novel magnetic phase diagram
(via sciencedaily.com) Original source Non-Heisenberg-type approximant crystals have many interesting properties and are intriguing for researchers of condensed matter physics. However, their magnetic phase diagrams, which are crucial for realizing their potential, remain completely unknown. Now, a team of researchers has constructed the magnetic phase diagram of a non-Heisenberg Tsai-type 1/1 gold-gallium-terbium approximant crystal. This development marks a significant step forward for quasicrystal research and for the realization of magnetic refrigerators and spintronic devices.

Published Translating nuclear waste site data into microbial ecosystem insights
(via sciencedaily.com) Original source A flagship seven-year study that explores how environmental stresses influence different ecological processes shaping the composition and structure of microbial communities in groundwater has now been published.
Published New potato-threatening pathogens reported for first time in Pennsylvania, US
(via sciencedaily.com) Original source As the home of many beloved snack companies, Pennsylvania values its potatoes. Tasty tubers across the state may face the threat of newly identified pathogen strains, though, according to researchers who made the finding and aim to develop management strategies.
Published Ancient 'chewing gum' reveals stone age diet
(via sciencedaily.com) Original source What did people eat on the west coast of Scandinavia 10,000 years ago? A new study of the DNA in a chewing gum shows that deer, trout and hazelnuts were on the diet. It also shows that one of the individuals had severe problems with her teeth.
Published Efficiently moving urea out of polluted water is coming to reality
(via sciencedaily.com) Original source Researchers have developed a material to remove urea from water and potentially convert it into hydrogen gas. By building these materials of nickel and cobalt atoms with carefully tailored electronic structures, the group has unlocked the potential to enable these transition metal oxides and hydroxides to selectively oxidize urea in an electrochemical reaction. The team's findings could help use urea in waste streams to efficiently produce hydrogen fuel through the electrolysis process, and could be used to sequester urea from water, maintaining the long-term sustainability of ecological systems, and revolutionizing the water-energy nexus.
Published HIV antibodies protect animals in proof-of-concept study
(via sciencedaily.com) Original source Three different HIV antibodies each independently protected monkeys from acquiring simian-HIV (SHIV) in a placebo-controlled proof-of-concept study intended to inform development of a preventive HIV vaccine for people. The antibodies -- a human broadly neutralizing antibody and two antibodies isolated from previously vaccinated monkeys -- target the fusion peptide, a site on an HIV surface protein that helps the virus fuse with and enter cells.
Published Nearly dead plants brought back to life: Keys to aging hidden in the leaves
(via sciencedaily.com) Original source Scientists have known about a particular organelle in plant cells for over a century. However, scientists have only now discovered that organelle's key role in aging.
Published Chemists create a 2D heavy fermion
(via sciencedaily.com) Original source Researchers have synthesized the first 2D heavy fermion. The material, a layered intermetallic crystal composed of cerium, silicon, and iodine (CeSiI), has electrons that are 1000x heavier and is a new platform to explore quantum phenomena.
Published Higher measurement accuracy opens new window to the quantum world
(via sciencedaily.com) Original source A team has developed a new measurement method that, for the first time, accurately detects tiny temperature differences in the range of 100 microkelvin in the thermal Hall effect. Previously, these temperature differences could not be measured quantitatively due to thermal noise. Using the well-known terbium titanate as an example, the team demonstrated that the method delivers highly reliable results. The thermal Hall effect provides information about coherent multi-particle states in quantum materials, based on their interaction with lattice vibrations (phonons).
Published Study throws our understanding of gene regulation for a loop
(via sciencedaily.com) Original source To function properly, the genetic material is highly organized into loop structures that often bring together widely separated sections of the genome critical to the regulation of gene activity. Scientists now address how these loops can help repress or silence gene activity, with potentially far-reaching effects on human health.
Published Machine learning reveals sources of heterogeneity among cells in our bodies
(via sciencedaily.com) Original source A team of scientists discovered the secrets of cell variability in our bodies. The findings of this research are expected to have far-reaching effects, such as improvement in the efficacy of chemotherapy treatments, or set a new paradigm in the study of antibiotic-resistant bacteria.
Published Let it glow: Scientists develop new approach to detect 'forever chemicals' in water
(via sciencedaily.com) Original source Researchers have created a new way to detect 'forever chemical' pollution in water, via a luminescent sensor.
Published Glowing COVID-19 diagnostic test prototype produces results in one minute
(via sciencedaily.com) Original source Cold, flu and COVID-19 season brings that now-familiar ritual: swab, wait, look at the result. But what if, instead of taking 15 minutes or more, a test could quickly determine whether you have COVID-19 with a glowing chemical? In a new study, researchers describe a potential COVID-19 test inspired by bioluminescence. Using a molecule found in crustaceans, they have developed a rapid approach that detects SARS-CoV-2 protein comparably to one used in vaccine research.
Published New insight into frictionless surfaces is slippery slope to energy-efficient technology
(via sciencedaily.com) Original source Scientists have made an insight into superlubricity, where surfaces experience extremely low levels of friction. This could benefit future technologies by reducing energy lost to friction by moving parts.

(via sciencedaily.com) Original source Scientists have successfully demonstrated new technologies that can obtain preserved tissue and high-resolution 3D images within minutes of encountering some of the most fragile animals in the deep ocean.
Published Tests can reveal whether an antibody can turn into a killer
(via sciencedaily.com) Original source A promising antibody failed testing. This is good news for developing a broad-spectrum antidote against the world's most dangerous snake venoms.
Published Study reveals a reaction at the heart of many renewable energy technologies
(via sciencedaily.com) Original source Chemists have mapped how proton-coupled electron transfers happen at the surface of an electrode. Their results could help researchers design more efficient fuel cells, batteries, or other energy technologies.
Published Unraveling the role of supersulfides in regulating mitochondrial function and longevity
(via sciencedaily.com) Original source Supersulfides, many of which are produced by cysteinyl-tRNA synthetase (CARS), are essential compounds across many different lifeforms.
