Disease-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.

Hospitals are riskier than farms when it comes to superbug transmission - but beware your pet
A deadly drug resistant bacterium that rivals MRSA is found in livestock, pets and the wider environment, but is rarely transmitted to humans through this route, scientists have found.

Vibrio 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.

Common 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.

Frequencies 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.

Antibiotic 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.

Bacteria 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.

Duplicate genes play key role in formation of legumes’ nitrogen fixing structures
Researchers have found that a duplication of the genes plays a key role in the processes governing the formation of symbiotic structures between nitrogen-fixing bacteria and leguminous plants.

SARS-CoV-2 alters functioning of RNA in infected cells
Researchers have shown that infection by SARS-CoV-2, the virus that causes COVID-19, changes the functioning of host cell RNA.

Humps and bumps provide home for microbes jumpstarting soil formation in glacial moraine
Scientists have discovered how topographical irregularities in barren substrates exposed by a melting Himalayan glacier are driving the formation of a variety of pioneering microbial communities that will pave the way for soil formation.

Probiotic ‘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.

Good friendships may make for a healthier gut microbiome
Researchers have found that sociable monkeys have more beneficial gut bacteria and fewer harmful gut bacteria.

Restoring 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.

Gut 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.

News
Viruses 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.

Carnivore 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 ...
