NewsTeen acne treatment can have knock-on impact on gut microbiome and maturing skeleton
Long-term use of systemic antibiotics to treat adolescent acne can perturb the gut microbiome, leading to altered profiles of circulating bile acids that reduce osteoblast function and bone mass accrual, researchers show.

NewsGenome studies uncover common ancestor for 600 scattered fungal species
About 600 seemingly disparate fungi that never found a good fit along the fungal family tree have been shown to have a common ancestor, according to a University of Alberta-led research team that used genome sequencing to give these peculiar lifeforms their own taxonomical grouping.

NewsHIV infection leaves memory that persists in cells even when virus is gone
A new study explains why people living with HIV may suffer from chronic inflammation, which can put them at an increased risk of developing comorbidities such as cardiovascular disease and neurocognitive dysfunction and how suppression or even eradication of HIV in the body may not resolve it. ...

NewsGene-delivering viruses cross into brain in step toward gene therapy for neurological diseases
A family of adeno-associated viruses (AAVs) has been developed that are capable of delivering gene therapies to the brain, a particularly challenging target tissue.

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.
