Published Mosquito saliva can weaken body's defenses against deadly dengue viruses, scientists discover
(via sciencedaily.com) Original source With dengue on the spread, the new discovery helps explain why dengue viruses are so easily transmitted. The finding could also lead to new ways to prevent infection.
Published Study to decode microbe-gut signaling suggests potential new treatment for IBD
(via sciencedaily.com) Original source Fresh insights into how our bodies interact with the microbes living in our guts suggest that a two-drug combination may offer a new way to treat inflammatory bowel diseases such as Crohn's disease and ulcerative colitis.
Published Antibiotic consumption and resistance 'two-way street' between animals and humans
(via sciencedaily.com) Original source Scientists have demonstrated that, globally, the association between antibiotic consumption and antimicrobial resistance (AMR) between human and animals goes both ways.
Published A new measurement could change our understanding of the Universe
(via sciencedaily.com) When it comes to measuring how fast the Universe is expanding, the result depends on which side of the Universe you start from. A recent study has calibrated the best cosmic yardsticks to unprecedented accuracy, shedding new light on what's known as the Hubble tension.
Published Ocean warming intensifies viral outbreaks within corals
(via sciencedaily.com) Original source A groundbreaking three-year study in the South Pacific has found evidence that ocean warming can trigger outbreaks of 'dinoflagellate-infecting RNA viruses' that attack symbiotic algae inside corals. Coral reef viruses have gained greater attention since being implicated in 2021 as a possible cause of stony coral tissue loss disease that has decimated Florida and Caribbean reefs for almost a decade.
Published Researchers assemble pathogen 'tree of life'
(via sciencedaily.com) Original source Researchers provide open-access tool to capture new data on a global plant destroyer, Phytophthora.
Published Galaxy clusters yield new evidence for standard model of cosmology
(via sciencedaily.com) Original source A new study probing the structure and evolution of galaxy clusters shows good agreement with the predictions of standard cosmological models.
Published New research shows that bacteria get 'hangry,' too
(via sciencedaily.com) Original source Researchers have discovered, using a recently developed technology, that genetically identical cells within a bacterial community have different functions, with some members behaving more docile and others producing the very toxins that make us feel ill.
Published Rising temperatures alter 'missing link' of microbial processes, putting northern peatlands at risk
(via sciencedaily.com) Researchers show that rising temperatures in northern regions may damage peatlands: critical ecosystems for storing carbon from the atmosphere -- and could decouple vital processes in microbial support systems.
Published Wastewater more potent breeding ground for antibiotic resistance than previously known
(via sciencedaily.com) Wastewater is a more potent environment for antibiotic resistance to evolve than previously known. A study shows that wastewaters have unique characteristics, allowing resistance genes to start their journey from harmless bacteria to those that cause disease.
Published Engineered E. coli delivers therapeutic nanobodies to the gut
(via sciencedaily.com) Original source Researchers have succeeded in developing an E. coli-based 'smart microbe' that secretes therapeutic payloads, including antibodies, into the gut. The genetically modified beneficial strain of bacteria blocks intestinal inflammation in a preclinical model of inflammatory bowel disease and has the potential to treat intestinal-based diseases.
Published Scallop eyes as inspiration for new microscope objectives
(via sciencedaily.com) Original source Neuroscientists have developed innovative objectives for light microscopy by using mirrors to produce images. Their design finds correspondence in mirror telescopes used in astronomy on the one hand and the eyes of scallops on the other. The new objectives enable high-resolution imaging of tissues and organs in a much wider variety of immersion media than with conventional microscope lenses.
Published Scientists observe flattest explosion ever seen in space
(via sciencedaily.com) Original source Astronomers have observed an explosion 180 million light years away which challenges our current understanding of explosions in space, that appeared much flatter than ever thought possible.
Published Form is (mal)function: Protein's shape lets bacteria disarm it
(via sciencedaily.com) Shigella bacteria can infect humans but not mice. A team can now explain why. Their findings may explain the multifariousness of a key weapon of our immune system.
Published Boosting the body's anti-viral immune response may eliminate aging cells
(via sciencedaily.com) Original source Aging cells express a protein that is produced by human cytomegalovirus and is targeted by certain immune cells in the body. Harnessing the immune response to this protein could have multiple health benefits during aging.
Published White-tailed deer blood kills bacteria that causes Lyme disease
(via sciencedaily.com) Original source As tick season kicks in across the country, scientists have completed research that offers a promising lead in the fight against Lyme disease.
Published How plants cope with the cold light of day -- and why it matters for future crops
(via sciencedaily.com) New research has discovered a cold 'coping' mechanism that is under the control of the plant biological clock and could offer solutions to breeding more resilience into crops less suited to cold climates.
Published New details of SARS-COV-2 structure
(via sciencedaily.com) Researchers used computational modeling to reveal finer details surrounding the outer shell of the COVID-19 virus. The work expands the scientific community's understanding of SARS-COV-2, and could lead to more refined antiviral therapies and better vaccines.
Published Astronomers witness the birth of a very distant cluster of galaxies from the early Universe
(via sciencedaily.com) Original source Astronomers have discovered a large reservoir of hot gas in the still-forming galaxy cluster around the Spiderweb galaxy -- the most distant detection of such hot gas yet. Galaxy clusters are some of the largest objects known in the Universe and this result further reveals just how early these structures begin to form.
Published How the gut creates a cozy home for beneficial microbiome species
(via sciencedaily.com) Original source The digestive tract of fruit flies remodels itself to accommodate beneficial microbiome species and maintain long-term stability of the gut environment, according to new research.
