NewsKimchi-derived probiotic found to promote binding and excretion of intestinal nanoplastics
Scientists have announced that a lactic acid bacterium isolated from kimchi can help promote the removal of nanoplastics from the body by binding to them in the intestine.

NewsNeanderthals may have used birch tar for its anti-bacterial properties
Scientists extracted tar from modern birch tree bark, specifically targeting species known from Neanderthal sites. When exposed to different strains of bacteria, all tar samples were found to be effective at hindering the growth of Staphylococcus bacteria known to cause wound infections.

NewsDiet determines the bacteria present in microbial gardens cultivated by ants
Researchers studying leafcutter ants have demonstrated how bacteria in the colonies respond to different diets provided by ants to the fungi they cultivate. The study paves the way for a better understanding of how colonies function and may lead to the discovery of new molecules for biotechnological use.

NewsDigital early warning systems essential as old diseases like cholera resurge in global crisis zones
A new critical analysis examines how the convergence of climate change, economic collapse, and conflict is bringing back a preventable disease once thought to be under control.

NewsMulti-strain probiotic therapy shows promise in preventing bacterial vaginosis recurrence
A global team of experts has identified a promising new approach to prevent recurrence of bacterial vaginosis (BV). In a phase 1 randomized clinical trial, researchers found that a short course of a multi-strain probiotic restored protective bacteria to the vagina, significantly reducing disease recurrence.

NewsStudy shows breath test can confirm bacterial infection
A study shows how molecules that are only broken down by infecting bacteria, and not by gut bacteria, can be used to confirm infection. By enriching these molecules with a naturally occurring carbon isotope, the researchers found that carbon dioxide produced when they break down is easily detected in a breath test.

NewsNew drug candidate extremely effective against H. pylori bacterium
Researchers have discovered that metronidazole targets two central protective proteins of Helicobacter pylori: an enzyme responsible for detoxifying harmful reactive oxygen species and a protein that repairs damaged proteins.

NewsNovel biosensing platform enables fingertip blood-based micro-volume t-cell immune monitoring
A new platform, known as Tip Optofluidic Immunoassay Interferon-Gamma Release Assay (TOI-IGRA), could revolutionize how people monitor their immune health. The platform allows for the precise quantification of pathogen-specific T-cell responses using a mere 15-25 μL of fingertip blood.

NewsPrototype breath tests spot bacterial infections in minutes
Researchers have adapted the long-used breath test for Helicobacter pylori, a bacterium that causes a common stomach infection, expanding the technology’s capabilities to detect a broader range of bacterial infections.

NewsA newly identified disease of corn and sorghum may be mistaken for iron deficiency
A newly identified bacterial disease affecting corn and sorghum can closely resemble iron deficiency, potentially leading farmers to apply costly nutrient treatments that do not address the underlying problem.

NewsLong-term biochar use reshapes soil carbon storage through microbial pathways
A new long-term study reveals that biochar, a carbon-rich material derived from crop residues, can significantly enhance soil carbon storage, but its effectiveness depends strongly on land use and soil type.

NewsFantastic fungi found with ability to freeze water
An international group of researchers has discovered the identity of fungal proteins that can catalyze ice formation at high subzero temperatures. One potential application of this discovery could be to engineer weather.

NewsScientists discover a bacterium that protects against long Covid
Scientists have discovered the key role played by a bacterium, Dolosigranulum pigrum, that is naturally present in the respiratory microbiome. When present in greater numbers, these bacteria are associated with a reduction in the persistence of symptoms characteristic of long Covid.

NewsEngineered bacteria deliver cancer drug directly inside tumors in mice
New research suggests that Escherichia coli Nissle 1917 (EcN) may be engineered with anticancer agents to treat cancerous tumors in mice. Researchers used EcN as a base for synthesizing Romidepsin (FK228), an FDA-approved drug with anti-tumor agents.

NewsTrace levels of food pathogen do not always translate to health risk, says study
Ultra-sensitive food safety tests may drive food waste and unavailability with limited public health benefit, according to a study. These food safety measures and ultra-sensitive tests may drive edible food being thrown away, excessive packaging, and extra costs for consumers.

NewsNew single‑cell technique reveals how tuberculosis‑like bacteria alter human cells
Researchers have developed a new technique to measure the content of individual human cells infected with bacteria that model tuberculosis – and it is already revealing biological changes that conventional analysis would miss.
-
NewsStudy maps how tuberculosis bacteria power themselves
A new study provides the first detailed 3D structure of a protein called EtfD, which the bacterium Mycobacterium tuberculosis uses to extract energy from lipids (fats), along with the first laboratory test capable of directly measuring its activity.

NewsScientists discover ‘consortium’ of bacteria cooperating to eat phthalate plasticizers that single microbes can’t stomach
Researchers have discovered a synergistic ‘consortium’ of plastic-eating bacteria, which can eat phthalate esters (PAEs) – plasticizers which are often found in building materials, food packages, and personal care products, but have been implicated in hormonal, metabolic, and developmental disorders and some cancers.

NewsNew study fills research gap in food safety to better protect pregnant women from Listeria
Researchers developed new biologically plausible dose-response models — one for maternal infection and one for stillbirth — built on data from guinea pigs and gerbils, which share key biological traits with humans relevant to listeria pathogenesis.

NewsOcean bacteria team up to break down biodegradable plastic
Researchers uncovered the role of individual ocean bacteria in the breakdown of a widely used biodegradable plastic. They also showed the complementary processes microbes use to fully consume the plastic, with one microbe cleaving the plastic into its component chemicals and others consuming each chemical.
