NewsVaccine for Lyme disease one step closer with promising six-month results
A vaccine for Lyme disease is one step closer after Pfizer Inc and Valneva SE reported positive results in their antibody persistence data six months after completing a three-dose or two-dose schdule in children and adults with vaccine candidate VLA15.

NewsGut microbiomes of mouse pups change for good when nursing mothers fed low-fibre diet
Researchers have found that when nursing mouse mothers are fed a low-fibre diet, their offspring’s microbiome is permanently altered, leading to gut inflammation and obesity.

NewsNew technique reveals marine microbes’ outsized role in carbon cycle
A small fraction of marine microorganisms are responsible for most of the consumption of oxygen and release of carbon dioxide in the ocean, new research suggests.

NewsLiquid-coated air filter inspired by carnivorous plant can improve early capture of airborne pathogens
Researchers have designed a new liquid-coated air filter that allows for improved early detection and analysis of airborne bacteria and viruses, including the one that causes COVID-19.

NewsNew contamination detection tool Squeegee targets low microbial biomass microbiomes
Researchers have developed a new contamination detection tool that can distinguish between a potential environmental contaminant and a genuine microbiome signal in low biomass studies – studies that contain little microbial DNA like breastmilk, placenta or amniotic fluid.

NewsResearchers find new viral entryway into host cells for Covid-19
A University of Ottawa-led team has found a new viral entry for SARS-CoV-2, suggesting it may be able to use proteins to infect a wider range of cells.

NewsImmune response discovery solves mystery of why colds are more common when it’s cold
Scientists say a newly discovered immune response inside the nose is suppressed by colder temperatures, offering evidence for why colds, flu and COVID-19 are more common in cooler months.

NewsPathogen capture method speeds up ID in children with bloodstream infections
Researchers have developed a fast and highly efficient engineered pathogen capture method which shortcuts the accurate detection of pathogens in small blood samples, potentially saving lives.

NewsCOVID-19 infection disrupts gut microbes, especially with antibiotics
Acute infection disrupts a healthy balance between good and bad microbes in the gut, especially with antibiotic treatment, researchers have found.

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.
