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 To find life in the universe, look to deadly Venus
(via sciencedaily.com) Original source Despite surface temperatures hot enough to melt lead, lava-spewing volcanoes, and puffy clouds of sulfuric acid, uninhabitable Venus offers vital lessons about the potential for life on other planets, a new paper argues.
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 Weather prediction models can also forecast satellite displacements
(via sciencedaily.com) Original source Researchers have found that modern weather models can accurately predict the energy that Earth emits and reflects into space, which directly affects the movements of low Earth-orbiting (LEO) satellites. By leveraging these models, the researchers gained insights into how LEO satellites respond to weather events below, such as tropical cyclones with tall and reflective clouds.
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 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.
Published Why can zebrafish regenerate damaged heart tissue, while other fish species cannot?
(via sciencedaily.com) Original source A heart attack will leave a permanent scar on a human heart, yet other animals, including zebrafish, can clear cardiac scar tissue and regrow damaged muscle as adults. Biologists sheds new light on how zebrafish heal heart tissue by comparing how this species responds to heart injury with medaka, a fish species that cannot regenerate cardiac tissue.
Published Potential new treatment path for lasting Lyme disease symptoms
(via sciencedaily.com) Original source Researchers have identified a potential new treatment for persistent neurological symptoms of Lyme disease, commonly seen even after antibiotic use. The study found that fibroblast growth factor receptor inhibitors, previously studied in cancer, significantly reduced inflammation and cell death in infected brain and nerve tissues.
Published Metabolic health before vaccination determines effectiveness of anti-flu response
(via sciencedaily.com) Original source The annual influenza vaccine has become less effective on average over time. One reason may be reduced vaccine efficacy in people with obesity than those with a healthier body mass index (BMI), while the number of people with high BMI grows. Findings showed switching mice to a healthy diet four weeks before influenza vaccination protected 100% from a later flu exposure, despite still having a high BMI.
Published Marine microbial populations: Potential sensors of the global change in the ocean
(via sciencedaily.com) Original source Animal and plant populations have been extensively studied, which has helped to understand ecosystem processes and evolutionary adaptations. However, this has not been the case with microbial populations due to the impossibility of isolating, culturing and analyzing the genetic content of the different species and their individuals in the laboratory. Therefore, although it is known that populations of microorganisms include a great diversity, this remains largely uncharacterized.
Published RNA's hidden potential: New study unveils its role in early life and future bioengineering
(via sciencedaily.com) Original source The origin of life continues to remain a matter of debate. The ribonucleic acid (RNA) world hypothesis proposes that 'ribozymes' which store genetic information and possess catalytic functions may have supported the activities of early life forms. Now, researchers explore how RNA elongation is regulated allosterically, shedding light on its impact on early life processes and offering insights into the fabrication of arbitrary RNA nanostructures with various modern applications.
