NewsMicrofossils interpreted as animal traces were actually algae and bactéria
A reexamination of microfossils found in Brazil shows that the marks previously interpreted as traces of worms or other small oceanic animals are actually communities of fossilized microscopic bacteria and algae.

NewsFrom ocean to gut: The bacteria that shape both human health and marine carbon cycling
A group of researchers has discovered that Akkermansia bacteria are not unique to our guts, but can also be found in the ocean. In both habitats they use similar skills to ensure their survival and success. They seem to carry an old and widespread survival toolkit.

NewsSelf-renewing bacteria offer new hope for heavy metal cleanup
Scientists have revealed a powerful bacterial defense strategy against Cd toxicity. The team found that Stenotrophomonas sp. H225 sheds Cd-laden cell wall fragments and rebuilds new protective layers through a process involving the mtgA gene.

NewsIntestinal stem cells can fight back against salmonella scientists discover
Researchers have shown that intestinal stem cells can directly sense intracellular Salmonella enterica bacteria and activate an inflammasome-dependent response. Following infection, the stem cells differentiate into antimicrobial Paneth cells, which secrete molecules that help limit bacterial persistence in the intestinal crypt.

NewsSwansea spin-out Bionema Group receives second King’s Award for Enterprise
Bionema Group Ltd, a Swansea University spin-out specialising in biological crop protection and sustainable agriculture, has been awarded the King’s Award for Enterprise: Sustainable Development 2026. It highlights Bionema’s contribution to developing environmentally sustainable alternatives to synthetic pesticides.

NewsCRISPR system inhibits hepatitis E virus
Researchers have developed a novel antiviral concept - using the CRISPR/Cas13 system, they were able to specifically suppress the replication of the hepatitis E virus in human cells.

NewsResearchers develop next-generation CRISPR biocontainment technology for controlling microbial survival without DNA cleavage
Researchers have employed a CRISPR-dCas9-based base editing system capable of introducing precise nucleotide changes without inducing DNA double-strand breaks. The researchers targeted the start codons of essential genes and irreversibly disrupted their function, permanently blocking cell survival.

NewsThawing Arctic soil awakens only half of soil microbes, new study reveals
A study shows that even after months of thawing, around half of the microorganisms in High Arctic soils remain dormant. This challenges the assumption that warming uniformly boosts microbial activity and carbon release from thawing permafrost.

NewsGut microbiota plays a role in metabolic health after bariatric surgery
Changes in gut microbiota after bariatric surgery are strongly linked to altered metabolic health and sustained improvement in type 2 diabetes. A study shows changes in gut bacterial composition and function are associated with metabolic improvements, including insulin release and blood sugar control.

NewsInvisible smart bug fights gum disease
Current treatments for periodontitis often fail because they cannot simultaneously eliminate stubborn bacterial biofilms and calm the runaway inflammation that follows. Now researchers have engineered a living bacterium that does both, in the right order.

NewsIron minerals help decide whether dissolved organic matter becomes microbial food or long-term carbon
A new study shows how iron oxide minerals can reshape dissolved organic matter before microbes begin to break it down. The research focuses on goethite, and reveals that mineral adsorption does not simply remove organic matter from water.

NewsExpanded tuberculosis screening does not speed up treatment initiation or improve survival in hospitalized patients with HIV
According to the EXULTANT trial, adding molecular tests on sputum, urine and stool samples does not appear to outperform the standard WHO-recommended diagnostic approach.

NewsHow soil bacteria help plants defend themselves against disease
A study reveals the mechanism by which surfactin, a molecule produced by beneficial soil bacteria, activates plants’ immune defences. This mechanism, distinct from the classical paradigm of immune recognition, relies on direct interaction with the plant cell membrane.

NewsAnti-CRISPR stops the protein assembly line in bacteria
Bacteria fend off invading viruses with molecular scissors that slice up viral DNA, but viruses can fight back with a molecular trick that stops the scissors from ever being made. A viral “anti-CRISPR” protein sits on the ribosome and jams it as a CRISPR protein named Cas12 begins to form.

NewsMouse study suggests high-fat diets during pregnancy worsen severe GI illness in preterm babies
A new mouse study suggests a link between a high-fat prenatal diet and induction of potentially deadly symptoms of necrotizing enterocolitis (NEC) in premature babies.

NewsHow bacteria ‘chat’ their way to carbon-neutral water treatment
Global climate goals demand that wastewater treatment plants transform their operations. A new review reveals that quorum sensing (QS), the chemical communication system bacteria use to coordinate behavior, could be the key.

NewsScientists discover how gut bacteria toxin invades colon cells to trigger cancer
A common gut bacterium, Bacteroides fragilis, drives colon tumor formation, potentially leading to colorectal cancer, by secreting a toxin that damages the lining of the colon. Researchers have now shown that the B. fragilis toxin BFT must first bind host receptor claudin-4 before it can cause damage.

NewsTuberculosis risk: promising approaches for screening and prediction
It is currently difficult to detect TB in its early stages, or predict who will go on to have TB, and therefore preventive treatment is not widely used. Researchers assessed whether a blood-based 3-gene host-response test can detect active tuberculosis and help predict future disease.

NewsHead impacts associated with altered gut microbiome in football players
Non-concussive head impacts—hits to the head that don’t cause clinically detectable symptoms—are correlated with subsequent changes to the gut microbiome in a small sample of US collegiate football players, according to a new study.

NewsMembrane complex aids rock-eating microbes in converting carbon dioxide to biomass
So-called rock-eating microorganisms obtain their energy to convert carbon dioxide (CO2) from inorganic sources. Using electron microscopy and infrared spectroscopy, researchers investigated the structure of DAB2 in the sulfur bacterium Halothiobacillus neapolitanus.
