NewsMicrobiome in wood warbler’s gut driven by evolution rather than diet
Scientists have found that differences among the microbes that live within wood warblers’ digestive tracts are not primarily driven by diet diversity, contrary to a recently proposed hypothesis.

NewsDisease-resistant corals can rescue their more vulnerable neighbours
Disease-resistant corals can be used to help “rescue” corals that are more vulnerable to disease, according to a study from the University of California, Davis, that monitored a disease outbreak at a coral nursery in Little Cayman, Cayman Islands.

NewsVibrio toxins force key proteins to build ‘roads to nowhere’
Toxins released by a type of bacteria that cause diarrhoeal disease hijack cell processes, forcing important proteins to abandon jobs that are key to proper cell function and assemble into ’roads to nowhere’, a new study has found.

NewsCommon fungus eradicates toxic mercury from soil and water
Researchers have found that the fungus Metarhizium robertsii removes mercury from the soil around plant roots, and from fresh and saltwater, and have genetically engineered the fungus to amplify its mercury detoxifying effects.

NewsFrequencies cloaked within song could trick systems into triggering deadly pathogen release
Researchers have shown how that the safe operation of a negative pressure room – a space in a hospital or biological research laboratory designed to protect outside areas from exposure to deadly pathogens – can be disrupted by an attacker armed with little more than a smartphone.

NewsAntibiotic resistant microbes in gut make C difficile more infectious
Scientists have found that Enterococcus – an antibiotic-resistant, opportunistic pathogen – works together with Clostridioides difficile in the human gut, reshaping and enhancing the metabolic environment in the gut so that C. difficile can thrive.
-
NewsBacteria behind biblical disease have potential to regenerate livers
Scientists have discovered that the bacterium that causes leprosy can reprogramme cells to increase the size of a liver in adult animals without causing damage, scarring or tumours.
-
NewsProbiotic ‘backpacks’ could treat inflammatory bowel diseases
Researchers have devised specialised nano-particles that can neutralise molecules linked to inflammatory bowel disease (IBD), and can be attached to beneficial probiotic bacteria targeting the gut.

NewsRestoring the gut biome after antibiotics could lead to better outcomes for ovarian cancer patients
Antibiotics routinely used in ovarian cancer care indiscriminately kill gut bacteria, leading to faster cancer progression and lower survival rates, according to recent Cleveland Clinic research.
-
NewsGut parasites could aid the spread of respiratory bugs in rabbits
Researchers have found that co-infection with one or more gut parasites increases shedding of Bordetella bacterium and could increase onward transmission.
-
NewsViruses deploy CRISPR system to thwart bacterial defences
Researchers have shown that viruses engineered with a CRISPR-Cas system can thwart bacterial defenses and make selective changes to a targeted bacterium – even when other bacteria are in close proximity.
-
NewsMonkeypox mutations cause virus to spread rapidly and dodge vaccines
Researchers at the University of Missouri have identified the specific mutations in the monkeypox virus that contribute to its continued infectiousness.
-
NewsCarnivore gut microbes can predict health of wild ecosystems
Gut microbes of wild marten (Martes americana) that live in relatively pristine natural habitat is distinct from the gut microbiome of wild marten that live in areas that are more heavily impacted by human activity, researchers have found. The finding highlights an emerging tool that will allow researchers and ...

NewsNew monkeypox study increases fear of potential escalation in central Africa
A new study of monkeypox infections in a remote area of the Democratic Republic of the Congo (DRC) shows transmission rates rising closer to the point where outbreaks are likely to be larger and more frequent.
-
NewsBacteria can be programmed as fast-responding pollution sensors
Scientists and engineers at Rice University have engineered living bioelectronic sensors based on bacteria that can quickly sense and report on the presence of a variety of contaminants.

NewsGut microbes drive brain circuit pruning for social development in zebrafish and mice
Gut microbes encourage specialized cells to prune back extra connections in brain circuits that control social behavior, new UO research in zebrafish shows

NewsInstitut Pasteur and UCSF QBI team up to create centre of excellence
The Institut Pasteur and UC San Francisco Quantitative Biosciences Institute (UCSF QBI) have announced a new partnership for the joint establishment of the Institut Pasteur-UCSF QBI Center of Excellence in Emerging Infectious Diseases, with planned operations in San Francisco and Paris.

NewsCOVID-19 virus increases risk of other infections by disrupting normal mix of gut bacteria
Infection with Covid-19 can reduce the number of bacterial species in a patient’s gut, with the lesser diversity creating space for dangerous microbes to thrive, a new study has found.

NewsSpores emit potassium ions to monitor their environment while in deep lethargy
A team of scientists have discovered how cells in deep lethargy decide while they sleep whether or not to return to life.

NewsExperimental monoclonal antibodies take the fight to Epstein-Barr virus
Researchers have discovered a panel of investigational monoclonal antibodies (mAbs) targeting different sites of the Epstein-Barr virus (EBV) blocked infection when tested in human cells in a laboratory setting.
