Published New principle for treating tuberculosis
(via sciencedaily.com) Original source Researchers have succeeded in identifying and synthesizing a group of molecules that can act against the cause of tuberculosis in a new way. They describe that the so-called callyaerins act against the infectious disease by employing a fundamentally different mechanism compared to antibiotic agents used to date.
Published Scientists capture immune cells hidden in nasal passages
(via sciencedaily.com) Original source Scientists uncover 'striking' immune cell populations poised to fight SARS-CoV-2 in upper airway.
Published This protein does 'The Twist'
(via sciencedaily.com) Original source The NMDAR is involved in numerous cognitive functions including memory. Its movements are tightly coordinated like a choreographed dance routine. Scientists have now figured out how the protein performs a difficult 'Twist'-like dance move. The discovery could lead to new drug compounds that bind to NMDAR more effectively.
Published Unraveling a key junction underlying muscle contraction
(via sciencedaily.com) Original source Using powerful new visualization technologies, researchers have captured the first 3-D images of the structure of a key muscle receptor, providing new insights on how muscles develop across the animal kingdom and setting the stage for possible future treatments for muscular disorders.
Published Scientists discover entirely new wood type that could be highly efficient at carbon storage
(via sciencedaily.com) Original source Researchers undertaking an evolutionary survey of the microscopic structure of wood from some of the world's most iconic trees and shrubs have discovered an entirely new type of wood.
Published Super-black wood can improve telescopes, optical devices and consumer goods
(via sciencedaily.com) Original source Thanks to an accidental discovery, researchers have created a new super-black material that absorbs almost all light, opening potential applications in fine jewelry, solar cells and precision optical devices.
Published Researchers identify unique phenomenon in Kagome metal
(via sciencedaily.com) Original source A new study focuses on how a particular Kagome metal interacts with light to generate what are known as plasmon polaritons -- nanoscale-level linked waves of electrons and electromagnetic fields in a material, typically caused by light or other electromagnetic waves.
Published Injury dressings in first-aid kits provide a new technique to reveal shark species after bite incidents
(via sciencedaily.com) Original source Scientists have revealed that injury dressings found in first-aid kits can reliably be used to identify shark species involved in bite incidents by deploying medical gauze to gather DNA samples from aquatic equipment, such as surfboards.
Published Precise genetics: New CRISPR method enables efficient DNA modification
(via sciencedaily.com) Original source A research group has developed a new method that further improves the existing CRISPR/Cas technologies: it allows a more precise and seamless introduction of tags into proteins at the gene level. This technology could significantly improve research on proteins in living organisms and opens up new possibilities for medical research.
Published What shapes a virus's pandemic potential? SARS-CoV-2 relatives yield clues
(via sciencedaily.com) Original source Two of the closest known relatives to SARS-CoV-2 -- a pair of bat coronaviruses discovered by researchers in Laos -- may transmit poorly in people despite being genetically similar to the COVID-19-causing virus, a new study reveals. The findings provide clues as to why some viruses have greater 'pandemic potential' than others and how researchers might go about identifying those that do before they become widespread.
Published Organic nanozymes have broad applications from food and agriculture to biomedicine
(via sciencedaily.com) Original source Nanozymes are tiny, engineered substances that mimic the catalytic properties of natural enzymes, and they serve a variety of purposes in biomedicine, chemical engineering, and environmental applications. They are typically made from inorganic materials, including metal-based elements, which makes them unsuitable for many purposes due to their toxicity and high production costs. Organic-based nanozymes partially overcome some of these problems and have the potential for a broader range of applications, including food and agriculture, but they are still in the early stages of development. A new paper provides an overview of the current state of organic nanozymes and their future potential.
Published Platypus and chicken reveal how chromosomes balance between the sexes
(via sciencedaily.com) Original source Geneticists uncover new insights into how sex chromosome systems work in the platypus and the chicken -- which will lead to better understandings of our own sex chromosome evolution and gene regulation.
Published How researchers turn bacteria into cellulose-producing mini-factories
(via sciencedaily.com) Original source Researchers have modified certain bacteria with UV light so that they produce more cellulose. The basis for this is a new approach with which the researchers generate thousands of bacterial variants and select those that have developed into the most productive.
Published MicroRNA study sets stage for crop improvements
(via sciencedaily.com) Original source MicroRNAs can make plants more capable of withstanding drought, salinity, pathogens and more. However, in a recent study scientists showed just how much we didn't know about the intricate processes plants use to produce them.
Published Fetal brain impacted when mom fights severe flu: New mouse study explains how
(via sciencedaily.com) Original source New research using live mouse-adapted influenza virus improves upon previous mouse experiments to explain how maternal infection impacts fetal brain development. The study also indicates fetal brain changes are more likely once the severity of the mother's infection meets a specific threshold.
Published From genes to jeans: New genetic insights may lead to drought resilient cotton
(via sciencedaily.com) Original source Cotton is woven into the very fabric of our lives, from soft T-shirts to comfortable jeans and cozy bedsheets. It's the world's leading renewable textile fiber and the backbone of a global industry worth billions. As climate change intensifies, cotton farmers face increasing challenges from drought and heat. However, new research offers hope for developing more resilient varieties that can maintain high yields even under water-stressed conditions.
Published New progress in research into malignant catarrhal fever in cattle
(via sciencedaily.com) Original source A research team has published a groundbreaking study on malignant catarrhal fever (MCF). This disease is caused by the alcelaphine gammaherpesvirus 1 (AlHV-1), which infects its natural host, the wildebeest. This study sheds light on the mechanisms by which this virus, which is asymptomatic and latent in the wildebeest, causes an oligoclonal expansion of CD8+ T lymphocytes in cattle, leading to the development of MCF.
Published Researchers trap atoms, forcing them to serve as photonic transistors
(via sciencedaily.com) Original source Researchers have developed a means to realize cold-atom integrated nanophotonic circuits.
Published Healthy diet with less sugar is linked to younger biological age
(via sciencedaily.com) Original source Researchers have found a link between following a diet that is rich in vitamins and minerals, especially one without much added sugar, and having a younger biological age at the cellular level.
Published Researchers decipher new molecular mechanisms related to biological tissue regeneration
(via sciencedaily.com) Original source A study opens new perspectives to better understand how the molecular mechanisms involved in regenerative medicine work. The study focuses on tumor necrosis factor- (TNF- ) and its receptors TNFR, molecules of key interest in biomedicine due to their involvement in multiple diseases such as obesity related to type 2 diabetes mellitus, inflammatory bowel disease and several types of cancer.
