Published Researchers create artificial cells that act like living cells
(via sciencedaily.com) Original source Researchers describe the steps they took to manipulate DNA and proteins -- essential building blocks of life -- to create cells that look and act like cells from the body. This accomplishment, a first in the field, has implications for efforts in regenerative medicine, drug delivery systems and diagnostic tools.
Published Study compares salmonella rates in backyard, commercial poultry farm samples
(via sciencedaily.com) Original source Researchers find less Salmonella on backyard poultry farms. But concerns remain about the prevalance of multidrug-resistant bacteria on both large and small farms.
Published Odor-causing bacteria in armpits targeted using bacteriophage-derived lysin
(via sciencedaily.com) Original source A research team has synthesized a lysin that during in vitro experiments targets bacteria responsible for producing odors in human armpits.
Published Dengue fever infections have negative impacts on infant health for three years
(via sciencedaily.com) Original source Dengue infections in pregnant women may have a negative impact on the first years of children's lives, new research has found.
Published The spiciness of mustard may depend on soil microbes
(via sciencedaily.com) Original source New study finds microbes may influence the taste of mustard seeds.
Published AI tool creates 'synthetic' images of cells for enhanced microscopy analysis
(via sciencedaily.com) Original source Researchers have developed a method to use an image generation AI model to create realistic images of single cells, which are then used as 'synthetic data' to train an AI model to better carry out single-cell segmentation.
Published AI can improve Alzheimer's treatment through the 'gut-brain axis'
(via sciencedaily.com) Original source Researchers are using artificial intelligence to uncover the link between the gut microbiome and Alzheimer's disease. Previous studies showed that Alzheimer's disease patients have changes in their gut bacteria as the disease develops. The study outlines a computational method to determine how bacterial byproducts called metabolites interact with receptors on cells and contribute to Alzheimer's disease.
Published Scientists discover the cellular functions of a family of proteins integral to inflammatory diseases
(via sciencedaily.com) Original source In a scientific breakthrough, researchers have revealed the biological mechanisms by which a family of proteins known as histone deacetylases (HDACs) activate immune system cells linked to inflammatory bowel disease (IBD) and other inflammatory diseases.
Published Switching off the light to see better
(via sciencedaily.com) Original source Researchers used structured light and switchable fluorescent molecules to reduce the background light from the out-of-plane regions of microscope samples. This method allowed for the acquisition of images that surpassed the conventional resolution limit, and it may be useful for further study of cell clusters and other biological systems.
Published Protein network dynamics during cell division
(via sciencedaily.com) Original source An international team has mapped the movement of proteins encoded by the yeast genome throughout its cell cycle. This is the first time that all the proteins of an organism have been tracked across the cell cycle, which required a combination of deep learning and high-throughput microscopy.
Published The enemy within: How pathogens spread unrecognized in the body
(via sciencedaily.com) Original source Some pathogens hide inside human cells to enhance their survival. Researchers have uncovered a unique tactic certain bacteria use to spread in the body without being detected by the immune system. In their study, they reveal the crucial role of a bacterial nanomachine in this infection process.
Published Magnetic with a pinch of hydrogen
(via sciencedaily.com) Original source Magnetic two-dimensional materials consisting of one or a few atomic layers have only recently become known and promise interesting applications, for example for the electronics of the future. So far, however, it has not been possible to control the magnetic states of these materials well enough. A research team is now presenting an innovative idea that could overcome this shortcoming -- by allowing the 2D layer to react with hydrogen.
Published More economical and sustainable rechargeable batteries
(via sciencedaily.com) Original source Lithium salts make batteries powerful but expensive. An ultralow-concentration electrolyte based on the lithium salt LiDFOB may be a more economical and more sustainable alternative. Cells using these electrolytes and conventional electrodes have been demonstrated to have high performance. In addition, the electrolyte could facilitate both production and recycling of the batteries.
Published New copper-catalyzed C-H activation strategy
(via sciencedaily.com) Original source Inspired by what human liver enzymes can do, chemists have developed a new set of copper-catalyzed organic synthesis reactions for building and modifying pharmaceuticals and other molecules. The new reactions are expected to be widely used in drug discovery and optimization, as well as in other chemistry-based industries.
Published New research defines specific genomic changes associated with the transmissibility of the monkeypox virus
(via sciencedaily.com) Original source Scientists have located and identified alterations in the monkeypox virus genome that potentially correlate with changes in the virus's transmissibility observed in the 2022 outbreak.
Published Key protein regulates immune response to viruses in mammal cells
(via sciencedaily.com) Original source Researchers have revealed the regulatory mechanism of a specific protein, TRBP, that plays a key role in balancing the immune response triggered by viral infections in mammal cells. These findings could help drive the development of antiviral therapies and nucleic acid medicines to treat genetic disorders.
Published Development of organic semiconductors featuring ultrafast electrons
(via sciencedaily.com) Original source Collaboration has led to the successful observation of these ultrafast electrons within conducting two-dimensional polymers.
Published Accelerating the discovery of new materials via the ion-exchange method
(via sciencedaily.com) Original source Researchers have unveiled a new means of predicting how to synthesize new materials via the ion-exchange. Based on computer simulations, the method significantly reduces the time and energy required to explore for inorganic materials.
Published Energy scientists unravel the mystery of gold's glow
(via sciencedaily.com) Original source EPFL researchers have developed the first comprehensive model of the quantum-mechanical effects behind photoluminescence in thin gold films; a discovery that could drive the development of solar fuels and batteries.
Published Light show in living cells
(via sciencedaily.com) Original source Observing proteins precisely within cells is extremely important for many branches of research but has been a significant technical challenge -- especially in living cells, as the required fluorescent labeling had to be individually attached to each protein. The research group has now overcome this hurdle: With a method called 'vpCells,' it is possible to label many proteins simultaneously, using five different fluorescent colors.
