Novel antibiotic compound shows promise against MRSA skin infections

The development of new antibiotics to treat superbugs and other bacterial infections is a global priority, with the rate of infections that cannot be treated with current antibiotics rising and presenting one of the biggest threats to human health.

Non-clinical safety assessment crucial for CRISPR-based gene therapies

The rapid evolution of CRISPR/Cas genome editing has redefined the possibilities of cellular and gene therapy, enabling precise correction, disruption, and regulation of disease-associated genes.

New technique finds bacteria to increase the vitamin B2 content of soya drinks

Researchers at DTU have developed a new method that can reduce the time needed to find new bacteria for fermentation.

Vibrio cholerae acquires antiviral defenses through horizontal gene transfer

Like most bacteria, Vibrio cholerae lives under constant attack from viruses. To survive, bacteria equip themselves with antiviral immune systems.

Korean skincare ingredient emerges as potential antibiotic candidate

Fans of Korean skincare may be familiar with 'hero ingredient' Madecassic acid for its skin-soothing properties, but researchers at the University of Kent have revealed its greater potential for use in the battle against antibiotic resistance.

Cola may quickly lower pH inside orthodontic clear aligners and shift oral bacteria within hours

Researchers found that cola exposure quickly lowered pH and altered the microbiome on the inner surface of clear aligners, with the greatest disruption observed when aligners were removed before drinking and then reinserted. In this small 24-hour study, wearing aligners during exposure appeared less disruptive than removing them, though the authors said the mechanism still needs further study.

Gut microbiota regulates intestinal epithelial cell function and plasticity

A research team led by scientists from the State University of Campinas (UNICAMP) in São Paulo, Brazil, has made significant progress in understanding the relationship between gut microbiota and intestinal cells.

Novel screening method boosts early diagnosis of leprosy

A new blood test combined with a standardized questionnaire and artificial intelligence may transform the way leprosy is diagnosed in Brazil. Researchers at the University of São Paulo (USP) tested the new test in Brazil using blood samples collected during a COVID-19 population survey.

How gut microbes may shape heart attack damage and recovery

This review argues that gut microbes and the metabolites they produce, especially SCFAs and TMAO, may shape how the heart responds to myocardial infarction through epigenetic pathways such as DNA methylation, histone modification, and non-coding RNAs. It also outlines potential intervention routes, including diet, probiotics, postbiotics, and metabolite-targeted therapies, while noting that much of the evidence remains translational and not yet clinically definitive.

AI helps researchers find antimicrobial peptides in Earth’s harshest habitats

Researchers built the Extreme Environment Microbiome Catalog from 78,213 genomes across global extreme habitats, revealing major taxonomic and biosynthetic novelty, including 32,715 representative species, nearly 4 billion non-redundant genes, and 163,693 biosynthetic gene clusters. They then used protein language models to identify 3,032 candidate non-toxic antimicrobial peptides, with 84 of 100 synthesized peptides showing antibacterial activity and low cytotoxicity in the 50 tested in mammalian cells.

Organ-on-chip model advances study of sexually transmitted infections

Sexually transmitted infections (STIs) not only impact an individual's health but also result in multibillion-dollar economic losses worldwide.

Study reveals how bacterial collagenase efficiently breaks down collagen

Collagen is an important protein that helps build the tissues of humans and animals. It is very strong because it is made of three protein strands twisted tightly together like a rope. Because of this sturdy structure, ordinary protein-cutting enzymes usually cannot break it down.

Pediatric experts say plain yogurt is safe from 6 months and belongs in a baby’s diet

An expert panel review says plain, whole yogurt with no added sugar or sweeteners can be introduced from 6 months as part of complementary feeding, provided it does not replace breast milk or infant formula as the main source of nutrition. It also explains that yogurt provides live microorganisms and key nutrients, is generally well tolerated, and helps address common myths about inflammation, mucus, acne, sugar, and safety.
