NewsMaldives is first country to achieve ‘triple elimination’ of mother-to-child transmission of HIV, syphilis and hepatitis B
The World Health Organization has validated the Maldives for eliminating mother-to-child transmission of hepatitis B, while maintaining its earlier validation for EMTCT of HIV and syphilis. This makes the Maldives the first country in the world to achieve ‘triple elimination’.

NewsWHO warns of widespread resistance to common antibiotics worldwide
One in six laboratory-confirmed bacterial infections causing common infections in people worldwide in 2023 were resistant to antibiotic treatments, according to a new World Health Organization (WHO) report.

NewsMeasles immunity 90% in BC’s Lower Mainland
In British Columbia’s Lower Mainland, 90% of people have detectable antibodies against measles, indicating high vaccine coverage and population protection, according to a new study.

NewsTwo-dose recombinant shingles vaccine is effective even accounting for prior receipt of live shingles vaccine
A target trial emulation was conducted to assess the effectiveness of recombinant zoster vaccine (RZV) accounting for prior receipt of live zoster vaccine (ZVL) and immunocompetence. The results suggest individuals vaccinated with ZVL should be revaccinated with two doses of RZV.

NewsPioneering gut health testing with a simple finger prick
Zinzino, the Scandinavian health and wellness company, has announced the launch of its innovative Gut Health Test. With a simple at-home finger prick, this is the first commercial test to measure what gut bacteria produce and how the body responds.

NewsToxoplasmosis: how the pathogen exploits its own envelope
Researchers have developed a novel imaging technique that allows reliable visualization of the process of endocytosis in Toxoplasma for the first time. The material enters the pathogen through a micropore in its cell membrane.

NewsSped-up evolution may help bacteria take hold in gut microbiome
A genetic mechanism inserts mutations into key DNA hotspots that enable bacteria to adapt to new environments, a new study finds.

NewsClimate change may increase the spread of neurotoxin in the oceans
Climate-driven oxygen loss in the Black Sea thousands of years ago triggered the expansion of microorganisms capable of producing the potent neurotoxin methylmercury. That is shown in a new study which suggests that similar processes could occur in today’s warming oceans.

NewsRevolutionizing bioplastics: a microbial platform for fully bio-based long-chain polyesters
Researchers have developed a scalable, end-to-end microbial process transforming plant oils into sustainable polyesters comparable to petroleum-based plastics.

NewsScientists develop safer and more sustainable antimicrobials to prevent infection of cow udders
A new study has unveiled an alternative class of potent antimicrobial compounds that could be used in the agriculture industry to combat multi-drug-resistant bacteria that cause bovine mastitis.

NewsExpanding the genetic toolkit: nitrogen-response promoters developed for Bacillus licheniformis
Promoters are crucial expression elements in synthetic biology, and Bacillus licheniformis serves as an excellent chassis cell for industrial production, but is restricted by a lack of nitrogen source-responsive promoters.

NewsMolecular bodyguard helps infections persist
Researchers have identified a key molecular player that helps bacteria survive the hostile environment inside the body. Their study reveals how the protein RfaH acts as a protective shield for bacterial genes — and points to new strategies for fighting persistent infections.

NewsEarth’s oxygen boom: a fresh perspective for a billion-year-old problem
A new study examines nickel and urea in early microbial habitats, showing how ancient cyanobacteria adapted to their chemical surroundings. By recreating Archean conditions in the lab, researchers uncovered clues about the delicate balances that shaped early cyanobacterial life.

NewsHow microbial strain variations influence neurobehavior
Microbial single nucleotide variations influence host cognitive behavior by regulating metabolism, a new study of merino sheep reveals.

NewsResearchers map correlations between gene variants and proteomes
Scientists have discovered a way to predict the effects of numerous mutations in yeast - a valuable tool for better understanding molecular mechanisms. Key to this discovery was a detailed analysis of the proteome – the collection of all proteins inside a cell.

NewsFrom glucose to gourmet: engineered bacteria churn out key food additive
Researchers used E. coli as the chassis to produce inosinic acid (IMP), a popular umami enhancer. By reprogramming the metabolic flux network of E. coli and introducing amino acid mutations in the key enzymes in the synthesis pathway, the yield was significantly increased.

NewsStudy finds HEPA purifiers alone may not be enough to reduce viral exposure in schools
In a secondary analysis of a study of 200 classrooms, researchers found respiratory viral exposures were still high in those with HEPA purifiers, suggesting additional interventions are needed.

NewsPoultry growers: Have you checked your water lines lately?
Water quality could impact the kind of microbial populations in poultry drinking water lines and lead to the buildup of a biofilm that can harbor pathogenic bacteria like Salmonella, according to a new study.

NewsTiny architects, titanic climate impact: scientists call for coccolithophores to get their own day
Five European research organisations have launched an initiative to make 10 October International Coccolithophore Day, highlighting their crucial role in regulating the planet’s carbon balance, producing oxygen, and sustaining the ocean ecosystems that underpin all life.

NewsProtein condensates determine a cell’s fate, yeast study reveals
To ensure they have all the information they need, molecules from throughout a cell gather and form aggregates that can have different consistencies: regions called “condensates”. Researchers have discovered how condensates contribute to cellular information exchange in yeast cells.
