NewsDecoding the chemical messengers: Gut microbes talk to the whole body through metabolites
A comprehensive review systematically maps how bacterial metabolites shape immune responses and diseases across organs.

NewsEngineered enzyme breakthrough offers sustainable solution for polyurethane plastic recycling
A research team has elucidated, for the first time, the catalytic mechanism by which the esterase Aes72 hydrolyzes urethane bonds in polyurethane (PU), and by engineering the enzyme to further enhance its catalytic efficiency.

NewsScientists develop therapeutic, nasally delivered DNA vaccine for tuberculosis
Research shows the vaccine — in combination with drug therapy — accelerated a relapse-free TB cure in mice, improved activity of a drug-resistant TB regimen and stimulated immune responses in nonhuman primates.

NewsA study links armed conflict in Colombia with higher tuberculosis cases and mortality
Areas with the highest intensity of conflict between 2008 and 2019 recorded a higher disease burden, highlighting the need for control strategies tailored to each territory.

NewsViruses ‘eavesdrop’ on each other – but it can backfire
Viruses can “eavesdrop” on each other using chemical signals – but it can backfire for the eavesdropper, new research shows. Scientists studied chemical communication by phages, viruses that infect bacteria.

NewsSimple blood test for gut bacteria metabolites could spot dementia years earlier
Scientists have discovered that subtle changes in the blood may reveal the earliest signs of cognitive decline long before symptoms become obvious.These changes are caused by chemicals produced by gut bacteria - reinforcing the idea that the gut–brain connection plays an important role in early memory changes.

NewsIntroducing environmental microbiota to urban homes shifts the indoor microbiome
Introducing forest soil on an entryway doormat shifted the indoor microbiome of Finnish homes closer to bacterial profiles found outdoors, with less contribution from human-associated bacteria, a new study shows.

NewsThesis confirms algae have strong wound-healing, skin-protective, and immune-supporting properties
New research demonstrates that polysaccharides extracted from various seaweeds and freshwater cyanobacteria possess remarkable bioactive properties and can accelerate wound healing, reduce inflammation, and protect skin cells from UV-induced damage.

NewsWorld-first discovery of noma-linked bacteria opens path to early diagnosis and prevention
Researchers have identified a bacterium strongly associated with noma disease, marking a major step towards earlier diagnosis and more effective treatment. They uncovered a previously undescribed species of Treponema bacteria, which may be responsible for the disease.

NewsUnexpected potential bacterial symbiosis found in fungus that causes angular leaf spot
Scientists have uncovered an unexpected microbial relationship that could help explain differences in the severity of a major disease affecting common beans. The discovery sheds light on how the pathogen evolves and may point to new strategies.

NewsBiochar–microbe partnership unlocks soil phosphorus and boosts tomato yields
A new study reveals that combining biochar with beneficial soil bacteria can significantly improve phosphorus availability, reshape plant development, and increase crop yields in greenhouse-grown cherry tomatoes.
-
NewsHow plants fight back against bacteria that promote waterlogging in leaves
Researchers clarify a humidity-driven plant defense against bacteria that limits water buildup, with potential implications for future crop protection strategies.

NewsMissing gut bacteria may prevent some people with celiac disease from fully benefiting from high-fiber supplements or diets
Many people with celiac disease are advised to eat more fibre to support digestion and manage symptoms, either through diet or prescribed fibre supplements. New research shows that the benefits of that fibre may depend on whether the right bacteria are present in the gut to break it down.

NewsBiochar from peanut shells boosts soil health and crop quality over the long term
A long-term field study across major agricultural regions in China has revealed that biochar made from peanut shells can significantly improve soil fertility and enhance crop quality by reshaping soil microbial communities.

NewsGetting a glimpse of viral dances in the dark in the Sargasso Sea
In a new study of viral abundance over a short time frame in the Sargasso Sea, researchers found that almost all viruses with cyclical changes in abundance were most active at night – a somewhat surprising find.
-
NewsResearch cracks genetic code of growing bacterial threat
Scientists have discovered that a fast‑rising strep bacterium comes in more forms than expected, including ones that may lead to life-threatening infections. Streptococcus dysgalactiae subspecies equisimilis (SDSE) was originally considered rare and was believed to mostly infect people who already had other health issues.

NewsStopping algae blooms with bacteria-busting buoys
Algae blooms make a pond’s surface shine in mesmerizing green hues. But if the microorganisms responsible are cyanobacteria, they can also release toxins that harm humans and wildlife alike. So, a team reporting in ACS ES&T Water has designed a “set it and forget it” system for distributing algaecide using ...

NewsCopper-loaded starch nanoparticles can target bacteria in microbial communities
Researchers have developed copper-loaded starch nanoparticles that can be broken down by specific bacteria to release antibacterial copper molecules. They hope that these nanoparticles can be used to target biofilms, which account for 50-70% of healthcare-associated infections.

NewsHow bacteria outsmart the immune system: Two-pronged strategy revealed
A team has uncovered how a common bacterial pathogen uses a single protein to quietly undermine the human immune system, by both shutting down key warning signals and blocking the cell’s ability to restore them.

NewsSoil bacteria break down toxic chemicals in the environment
Soil bacteria can help to break toxic aromatic compounds down. For one of these, Rhodococcus opacus 1CP, researchers have analyzed the genome and identified many potential metabolic pathways that the bacterium can employ to act as a ‘clean-up specialist’.
