NewsDangerous E. coli strain blocks gut’s defense mechanism to spread infection
When harmful bacteria invade through the digestive tract, gut cells usually fight back by pushing infected cells out of the body to stop the infection from spreading. Scientists have discovered that a dangerous strain of E. coli can block gut this defense, allowing the bacteria to spread more easily.

NewsDusty air is rewriting your lung microbiome
Dust from California’s drying Salton Sea doesn’t just smell bad. Scientists found that inhalation of airborne dust collected close to the shallow, landlocked lake alters both the microbial landscape and immune responses in mice that were otherwise healthy.

NewsHow a pyrite-oxidizing microbe helps preserve atmospheric oxygen in sulfate
Research shows that O₂ in sulfate deposits, coupled with geochemical clues, could help identify microbial activity in Earth’s rock record and even in Martian sediments.

NewsBacteria deliver synthetic, animal-free way to grow organoids in 3D
Researchers have developed a completely animal-free gel to grow organoids, miniature three dimensional versions of organs. By combining the bacterial protein invasin with a synthetic gel, they created an environment in which organoids can grow and expand long-term.

NewsCommon source, common food vehicle: investigations of recurring Salmonella Strathcona outbreaks in Europe since 2011
Across 17 countries and over a time span of 14 years, 662 cases of the rare Salmonella type have been identified – and linked to small tomatoes from Sicily.

NewsArtificial ocean carbon recycling system converts seawater CO2 into valuable chemicals
Researchers have developed an artificial ocean carbon recycling system that captures CO2 from seawater and uses microbes to directly convert it into succinic acid.

NewsScientists develop a way to track donor bacteria after fecal microbiota transplants
Researchers have developed a new technology to track beneficial bacteria for up to 5 years after fecal microbiota transplants (FMT). The method allows scientists to distinguish even closely related bacterial strains and identify each one’s unique genetic “fingerprint.”

NewsDoes floral scent affect insect visitors and bacterial strains on flowers?
A new study reveals that high floral scent chemodiversity is associated with increased pollinator richness but reduced bacterial richness on flowers. The findings led the scientists to propose the ’Filthy Pollinator Hypothesis’.

NewsMicrobes at Red Sea vents show how life and geology shape each other
A new study led by King Abdullah University of Science and Technology (KAUST; Saudi Arabia) Professor Alexandre Rosado has revealed an unusual microbial world in the Hatiba Mons hydrothermal vent fields of the central Red Sea, a site first discovered by one of his co-authors and colleagues, Assistant Professor Froukje ...

NewsNew role of gut bacteria provides hope for a novel IBS treatment
Research clarifies the complex interaction between gut bacteria and IBS, identifying two bacteria that together can produce serotonin: Limosilactobacillus mucosae and Ligilactobacillus ruminis.

NewsUS funding cuts could result in nearly 9 million child tuberculosis cases, 1.5 million child deaths
A new study projects that US funding cuts to global health aid will have a catastrophic effect on pediatric TB, with children in Sub-Saharan Africa and Southeast Asia likely to experience a spike in preventable cases and deaths over the next decade.

NewsAre there living microbes on Mars? Check the ice, researchers say
By recreating Mars-like conditions in the lab, researchers demonstrated that fragments of the molecules that make up proteins in E. coli bacteria, if present in Mars’ permafrost and ice caps, could remain intact for over 50 million years.

NewsStudy reveals how bacteria in tumors drive treatment resistance in cancer
Researchers have uncovered a previously unknown way for microbes within tumors to contribute to treatment resistance in certain cancers. The study finds these microbes push cancer cells into a reversible resting state, allowing them to become resistant to certain chemotherapies.
