NewsUnderground methane leaks may cultivate microbes that help consume them
Researchers have identified where naturally occurring soil microbes consume methane released from underground natural gas leaks. Methane-consuming microbes were most active in a narrow zone near the surface where methane rising from below meets oxygen entering from the atmosphere.

NewsAn enzyme with potential: New type of plastic-degrading enzyme discovered in bacteria
Researchers have identified a new enzyme that can not only degrade certain polyesters and bioplastics, but also might provide bacteria with resistance to antibiotics. The discovery raises hopes that microorganisms can adapt to plastic degradation more rapidly than previously thought.

NewsWhere do dissimilatory iodate-reducing microorganisms live in the ocean?
Scientists have discovered that dissimilatory iodate-producing microorganisms do not live above marine oxygen minimum zones (OMZs) as long predicted - instead thriving within the OMZs, converting iodate into iodide and promoting the release of marine iodine into the atmosphere.

NewsImmune drug anifrolumab linked to lower risk of infection and hospitalization for skin lupus
Preliminary results from an investigator-initiated single-site clinical study show that some people with chronic cutaneous lupus erythematosus are less likely to acquire life-threatening infections when taking the drug anifrolumab.

NewsBeneficial bacteria support tomato growth & suppress disease
A new study has identified bacterial strains that both treat tomato bacterial canker—some by delaying the onset of infection up to a week—and promote the growth of the plant.

NewsGut bacteria linked to key brain chemicals in first-of-its-kind human study
New research provides human evidence for a biological link between the gut microbiome and brain function.

NewsGoniothalamin as a dual-target medicinal chemistry candidate against antibiotic-resistant bacteria
A new computational study has found that goniothalamin — a natural plant compound — binds tightly to two critical bacterial proteins in drug-resistant Staphylococcus aureus and Escherichia coli, suggesting it could form the basis of a new class of antibacterial agents.

OpinionWhen do human-driven changes to wildlife microbiomes become a One Health concern?
Animals live in close partnership with communities of microbes that support digestion, immune development, and defence against pathogens, but human activities are changing those partnerships, says Katherine M. Lagerstrom.

NewsAntarctica is home to microbes found nowhere else on Earth
Researchers have found evidence that specific microbes in Antarctica’s soils are endemic — located on the continent and nowhere else on Earth.

NewsSwimming in rivers and lakes linked to higher risk of stomach bugs and rashes
Researchers have found that people swimming in rivers and lakes were more than twice as likely to develop skin problems, while higher levels of bacteria linked to faecal pollution were associated with an increased risk of stomach bugs.

NewsSurvival of the driest: Directed evolution boosts bacterial tolerance to industrial spray-drying by 1000-fold
Spray-drying is the preferred method for producing dry microbial inoculants for agriculture, offering low cost and easy transport. But many beneficial Gram-negative bacteria struggle to survive the rapid dehydration and heat involved.

NewsPropionate from gut bacterium Akkermansia mitigates liver fibrosis
A recent study has identified the gut commensal bacterium Akkermansia muciniphila as a potent modulator of liver fibrosis.
-
NewsTraditional Chinese medicine compound shows promise against ischemic stroke by targeting the gut-brain axis
Researchers have uncovered new evidence that a polysaccharide derived from the traditional medicinal herb Astragalus membranaceus (Huangqi) can protect against ischemic stroke by acting through an unexpected route: the gut.
-
NewsEven ancient bacteria possessed intercellular communication structures like humans today
Communication between cells in plants, animals and humans takes place via specialised connecting structures. Researchers have discovered how the regulation of very similar structures was already present in multicellular bacteria.
-
NewsA bacterial protein fragment drives tissue fibrosis, but antibody treatment can help
A bacterial protein fragment called corisin drives the process of pulmonary fibrosis by infiltrating and disrupting the cell’s quality-control system, researchers found in a new study. Meanwhile, blocking corisin with an antibody impeded the damage.
-
NewsMicrobiome signaling system could open new paths for treating IBS-related constipation
New research expands scientists’ understanding of how the gut microbiome communicates with the body, and how our gut bacteria work together to control intestinal movement.
-
NewsResearcher awarded two NIH grants to advance research on antibiotic-resistant infections
The research is focused on developing new strategies to combat two infectious diseases: catheter-associated urinary tract infections (CAUTIs) and invasive Group A Streptococcus skin infections, both of which are increasingly difficult to treat because of antimicrobial resistance.
-
NewsDietary tryptophan prevents sepsis
Dietary tryptophan protects against sepsis through gut microbiota-derived metabolites which enhance macrophage bacterial phagocytosis.
-
NewsImmune responses to urinary tract infection linked to birth outcomes
A new study shows that the increased risk of preterm pregnancies associated with urinary tract infection, is linked to the body’s immune response to the infection rather than to the bacteria themselves.

NewsFor Legionella bacteria, taking over a cell means playing by its rules
New research demonstrates how a protein produced by Legionella mimics the behavior of the host cell’s own proteins.
