NewsHow cells fight back after bacterial toxins break through
Understanding how epithelial cells rapidly repair toxin-induced membrane injuries is important for understanding how tissues withstand bacterial attacks. Researchers have uncovered a lipid signaling pathway that helps epithelial cells respond to membrane injury.

NewsScientists use bacteria to produce muconic acid from plants
Researchers have engineered a soil bacterium to synthesize muconic acid, a valuable chemical in the manufacturing industry, from plant matter.

NewsStaphylococcus aureus is highly resistant and virulent in milk
Staphylococcus aureus is frequently found in human and veterinary infections. Its ability to withstand antibiotic treatment makes it a major clinical challenge. To better understand the factors underlying this resistance, the scientists investigated the growth of the bacterium in two environments relevant to infection: milk and serum.

NewsBacterial immunity—or a form of sex?
Researchers have found that, under starvation stress, E. coli can use bacteriophages and CRISPR-Cas immunity to transfer and incorporate DNA, accelerating genetic reshuffling. The process resembles a primitive form of sexual reproduction and may help bacterial populations adapt to changing conditions.

NewsStudent earns competitive fellowship for research on corn’s defense against bacteria
New funding has been awarded for research focused on understanding how plants protect themselves against pathogens. Peyton Sorensen looks specifically at corn and two of its bacterial pathogens: Xanthomonas and Clavibacter, which cause bacterial leaf streak and Goss’s bacterial wilt and blight, respectively.

NewsHeel-prick blood samples from newborns could provide important insights into protection against serious infection
Heel-prick blood samples from newborns can be used to measure antibodies against Group B Streptococcus, according to a new study. In the longer term, the method could contribute to the development of vaccines designed to protect infants against serious infections.

NewsHow gut bacteria can shape the brain’s response to stroke
How much damage a stroke causes in the brain depends strongly on how quickly blood flow can be restored. The patient’s own immune response that follows the stroke also plays an important role. Researchers have identified a specific bacterial signal that shapes this immune response and influences stroke outcome.

NewsCRISPR nanodroplet technology offers a new strategy for rapid, multiplexed, species-level identification of mycobacteria
In a new commentary, researchers discuss the clinical and technological potential of a CRISPR-assisted nanodroplet platform, highlighting its ability to combine broad-range amplification, species-specific CRISPR recognition, fluorescence encoding, and microfluidic droplet pairing within a single diagnostic architecture.

NewsResearch uncovers how bacteria fight viruses, opening the door to better virus-based antibiotics
New research has revealed that bacteria detect viruses when a viral enzyme cuts an important sensor molecule in the bacterium, kicking off the immune response. The discovery paves the way for development of better phage therapies that can evade the bacterial immune system.

NewsSugar amplifies damage done to gut health by antibiotics
Eating sweets while taking antibiotics may worsen the harm done by the drugs to the normal community of bacteria in the gut, a new study has found. The study of hospitalized cancer patients found an additional 21% reduction in the variety of helpful bacterial species present for every 100 grams of sugar consumed in the 48 hours before treatment.

NewsFrom silent killer to cellular fuel: chemist unlocks nature’s carbon monoxide sensors
While carbon monoxide (CO) is widely feared as an odorless, deadly household hazard, nature views it quite differently. In the microscopic world, carbon monoxide serves as an essential cellular messenger and a vital lifeline of energy for microbes thriving in harsh environments.

NewsGel and water reveal bacteria’s hidden world
What if the answer to seeing beyond the limits of a microscope was simply to make the bacteria bigger? Scientists have used gel and water to physically expand tiny cells, revealing structures that conventional optics struggle to resolve. The technique gave researchers a clearer view of Chlamydia and new insight into how its DNA is organised.

NewsWater transformed into a weapon against antibiotic-resistant bacteria
Engineers have developed a new approach for turning ordinary water into a weapon against antibiotic-resistant bacteria, according to a study that hinges on a new kind of crystal made from titanium dioxide. These crystals transform the normal oxygen molecules in water into a special molecule known as “singlet” oxygen.

NewsCell by cell: New machine-learning-based method reveals what can make bacteria dangerous
A new method detects fluorescently labelled bacteria inside human cells and uses machine learning to analyse microscopy images. This allows researchers to measure, in the same experimental system, how efficiently bacteria enter cells, how strongly they accumulate inside them, and what kind of DNA damage they induce.

NewsIn African lakes, microbes living on algae reduce a powerful greenhouse gas
Lakes emit as much methane as agriculture. Researchers have shown that, in 79 African lakes, bacteria living on the surface of microalgae act as a natural filter. The greener the water becomes, the more these methanotrophs break down this powerful greenhouse gas.

NewsWHO reports latest global trends in cholera, meningitis and plague
Cholera deaths increased by 30% in 2025, despite fewer cases being reported to the World Health Organization (WHO). In 2025, 47 countries reported 451 499 cholera cases and 7870 deaths to WHO, the highest number of annual cholera deaths reported to WHO since 1999.

News Distinct gut microbiome patterns found in 5 cancer groups and in early-onset cancers
Researchers have discovered distinct gut microbiome patterns in adults 50 or younger with colorectal and breast cancers compared with those diagnosed later in life — one of several findings from an analysis of stool samples from 1,364 patients with cancer across cancer types, stages and treatments.

NewsOne Health model links spillover, microbiomes and governance to global risk
Global health risks continue to emerge where people, animals and the environment meet. A new review highlights that managing these threats requires more than reacting to individual outbreaks: health systems need to monitor the biological, ecological and institutional conditions that allow risks to build.

NewsResearch illuminates the bustling molecular communities inside bacterial cells
Scientists have often thought of cells as small bustling cities with parts that resemble factories, power grids, and shipping systems. Past research hasn’t had the tools to probe more deeply into how those different components interact, but researchers have now deployed cryo-electron tomography to visualise how different cellular processes are connected.

NewsResearchers develop AI tool that reveals hidden clues in the gut microbiome
Researchers are using artificial intelligence to uncover hidden clues among the trillions of bacteria living in the human gut, including changes that could one day help scientists detect diseases earlier.
