Postbiotic could reduce the risk of brain damage after a concussion

18/08/2026 - Giving mice a byproduct produced by gut bacteria reduced their risk of severe brain damage and cognitive difficulties after a traumatic brain injury

Global transmission architecture of VIM carbapenemases reveals host-specific dissemination strategies

17/08/2026 - Carbapenemase-producing Gram-negative bacteria carrying Verona integron-encoded metallo-β-lactamase (VIM) pose a persistent global threat, yet the mechanisms driving their worldwide dissemination...

The bacteria that make cheese taste so good may also benefit your gut

17/08/2026 - Scientists studying three artisan British cheeses found that the microbes responsible for their distinctive flavors may also offer surprising benefits for gut health. As the cheeses matured, helpful...

When seeps give ANME-SRB the cold shoulder: putative role of denitrification mediated methane oxidation in an Antarctic Cold Seep

10/08/2026 - Antarctica represents a significant, unresolved, and unstable source of methane to the atmosphere. To advance our understanding of the biological filter of methane in Antarctica, here we identify the...

Found in translation: CCA-adding enzymes reveal bacterialization of Asgard archaea prior to eukaryogenesis

10/08/2026 - CCA adding enzymes are essential for transfer RNA (tRNA) maturation and translation among all domains of life. A long standing dogma holds that archaea encode exclusively class one CCA adding enzymes...

Postbiotic supplement boosts body’s own GLP-1 and weight loss

07/08/2026 - A small trial suggests a supplement containing dead bacteria could offer a cheaper alternative to weight-loss drugs such as semaglutide, but further evidence is needed

Scientists discover bacteria that lock toxic uranium into a stable form

09/08/2026 - Deep underground, bacteria may be capable of doing something remarkable: trapping toxic uranium before it spreads. When researchers fed microbes in uranium-contaminated mine water with glycerol,...

Scientists find unexpected life on Ötzi the Iceman’s 5,300-year-old body

07/08/2026 - More than 5,000 years after his death, Ötzi the Iceman is still hosting a remarkable mix of ancient and modern microorganisms. Researchers separated microbes that lived in his body during his...

A method for comparing inferred evolutionary accumulation dynamics across covariates and model structures

- In this note we describe a method for comparing inferred dynamics in evolutionary accumulation models (EvAMs). These models involve the acquisition of multiple, potentially codependent, binary...

Cancer-fighting chewing gum cuts HPV levels by up to 93%

04/08/2026 - A specially engineered chewing gum reduced HPV by up to 93% and nearly eliminated two bacteria linked to head and neck cancer. The treatment preserved beneficial mouth bacteria, raising hopes for a...

Naturally cysteine-less LOV domains from halophilic archaea exhibit magnetic field effects on their fluorescence

02/08/2026 - Magnetic fields can modulate the function of certain flavoproteins through the radical pair mechanism, in which they influence the spin evolution of a coherent pair of radicals. This process can...

Field persistence of entomopathogenic fungi and network-level associations within the soil microbial community as biocontrol agents

28/07/2026 - The effects of entomopathogenic fungi (EPF) on native soil microbiota are not well understood. Here, we investigated the persistence of Metarhizium brunneum and Beauveria bassiana as preventive...

Scientists revive a powerful antibiotic that superbugs had defeated

22/07/2026 - Scientists have found a way to revive vancomycin, a powerful antibiotic that some dangerous bacteria have learned to resist. Instead of creating an entirely new drug, researchers paired vancomycin...

Scientists found mystery bacteria inside one of the ocean’s most elusive whales

21/07/2026 - Scientists studying decades of pygmy sperm whale strandings have uncovered three previously unknown types of Helicobacter bacteria hiding in the animals’ stomachs. All four infected whales showed...

Supplement that binds to microplastics may remove them from our body

17/07/2026 - A supplement comprised of dead bacteria seems to remove microplastics, and prevent their absorption into cells, by attracting them to the bacteria's rough surfaces

Scientists tested 39 sweeteners and found unexpected gut effects

17/07/2026 - A large laboratory study found that many commonly used sweeteners can directly change the growth of gut bacteria. Researchers identified more than 100 cases in which sweeteners behaved differently...

New “living plastic” self-destructs in just 6 days without leaving microplastics

16/07/2026 - Researchers have created self-destructing living plastic that uses engineered bacteria to completely break itself down when activated. The material degrades in just six days without creating...

Higher-Order Cell Tracking Transformer

- Reconstructing lineages from live-imaging microscopy requires linking cell detections across time, including through cell divisions. A common approach is to construct a candidate graph and associate...

Phenotypic expression of the gene‐for‐gene interaction in plant pathogenic bacteria: An implication for resistance to bacterial diseases by plants

13/07/2026 - Plant pathogenic bacteria cause massive losses in agriculture and damage to natural plant habitats. Bacterial pathogens not only reduce crop production, but they also reduce crop quality by releasing...

Differential proteomics of bacteria grown in vitro and in planta reveals functions used during growth on maize roots

12/07/2026 - Microbes are ubiquitous in the rhizosphere and play crucial roles in plant health, yet the metabolisms and physiologies of individual species in planta remain poorly understood. In this study, we...

Infant acquisition of Stickland-metabolizing bacteria prevents Clostridium botulinum infection

12/07/2026 - Infant botulism is caused by intestinal colonization with Clostridium botulinum , whereas healthy adults are resistant. Although the gut microbiota has long been implicated in protection against C....
