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 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 Can investigators use household dust as a forensic tool?
(via sciencedaily.com) Original source It is possible to retrieve forensically relevant information from human DNA in household dust.
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 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 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.
Published Earth prefers to serve life in XXS and XXL sizes
(via sciencedaily.com) Life comes in all shapes in sizes, but some sizes are more popular than others, new research has found. A survey of body sizes of all Earth's living organisms has uncovered an unexpected pattern. Contrary to what current theories can explain, our planet's biomass -- the material that makes up all living organisms -- is concentrated in organisms at either end of the size spectrum.
Published Is it COVID-19 or the flu? New sensor could tell you in 10 seconds
(via sciencedaily.com) Have a cough, sore throat and congestion? Any number of respiratory viruses could be responsible. Today, scientists report using a single-atom-thick nanomaterial to build a device that can simultaneously detect the presence of the viruses that cause COVID-19 and the flu -- at much lower levels and much more quickly than conventional tests for either.
Published Research into birds killed in window collisions reveals their microbiomes
(via sciencedaily.com) Researchers collected the bodies of birds that crashed into buildings while migrating, and used these specimens to learn about the relationship between birds and the microbes living in their guts -- which appears to be wildly different from mammals and their microbiomes.
Published Team designs molecule to disrupt SARS-CoV-2 infection
(via sciencedaily.com) A team of scientists designed a molecule that disrupts the infection mechanism of the SARS-CoV-2 coronavirus and could be used to develop new treatments for COVID-19 and other viral diseases.
Published Human body a breeding ground for antimicrobial resistance genes
(via sciencedaily.com) The community of microbes living in and on our bodies may be acting as a reservoir for antibiotic resistance, according to new research.
