NewsPlants can tell beneficial bacteria apart — and dose matters
A study reports that melon plants perceive and respond differently to two phylogenetically similar Bacillus strains. Bacillus subtilis NCIB3610 and B. velezensis FZB42 — despite colonizing roots with similar efficiency — trigger fundamentally different host programs.

NewsBeyond antibiotics—a paradigm shift toward bacteria-control-centric therapies
A novel extracellular vesicle platform helps polymyxins kill multidrug-resistant gram-negative bacteria at lower and potentially safer doses.

NewsPartners in crime produce extreme antibiotic resistance
A study shows how environmental bacteria enter the lungs during an infection and transfer antibiotic resistance genes to disease-causing bacteria.

NewsIndustrial poultry farming is accelerating the spread of a major foodborne disease
A new study reveals that industrial poultry farming has led to more than 100-fold increase in the movement of Campylobacter, allowing strains that once circulated in wild birds to mix extensively in commercial poultry populations.

NewsAnaerobic dry processing unlocks flavor precursors in Arabica coffee beans
A research team has mapped how four post-harvest processing methods reshape flavor precursors in Arabica coffee beans, showing that anaerobic fermentation substantially increases key non-volatile metabolites linked to aroma, flavor, acidity, body, and balance.

NewsThe Great Barrier Reef has a microbiome too
A study documents over 800,000 microbial genomes, identifying over 500 new bacterial species and over 300,000 distinct viruses in the waters of the Great Barrier Reef.

NewsHow a pandemic detour helped researchers uncover clues to a mysterious disease
Researchers examined the environmental and human factors that influence the distribution of Buruli ulcer, a neglected tropical disease caused by the bacterium Mycobacterium ulcerans.

NewsRecycling food waste would bring huge benefits, but microplastics a challenge
A first nationwide look shows diversion of U.S. food waste from landfills could reduce related climate impacts by 89% and nutrient pollution by 50%, researchers say.

NewsGut microbiomes follow distinct trajectories during urbanization across South Asia
An international team of researchers studied communities across India and Sri Lanka to understand the impact of urbanization, local diets, and culture on the gut microbiome.

News A secret weapon against superbugs
A molecular library of potential adjuvants has been used to help restore the activity of vancomycin, a powerful antibiotic widely used to treat serious infections such as MRSA and Clostridium difficile (C. diff).

NewsHow the encephalomyocarditis virus hijacks host protein machinery
Researchers have used cryo-electron microscopy (cryo-EM) to decode how the encephalomyocarditis virus (EMCV) IRES hijacks the host’s protein synthesis machinery.

NewsMany countries overusing powerful antibiotics
Many countries are using too many powerful and inappropriate antibiotics, fuelling antibiotic resistance concerns, while millions lack access to the specific drugs they need. That is according to a major international study of antibiotic use.

NewsIs the licensed Zaire ebolavirus vaccine suitable to combat the current Bundibugyo ebolavirus outbreak?
Researchers provide evidence of possible cross-protection through an already licensed Zaire ebolavirus vaccine.

NewsResearchers find link between gut bacteria byproduct and irregular heart rhythm
A study shows a connection between elevated blood levels of TMAO (trimethylamine N-oxide) — a byproduct of gut bacteria digestion of nutrients found in red meat and other animal products — and a higher risk of atrial fibrillation.

NewsStudy uncovers new path toward fighting malaria
Researchers have discovered that the malaria parasite relies on a specific type of fat to survive and multiply within the human host, uncovering a previously unknown vulnerability that could help guide future treatments.

NewsNew open-access database maps pathogens and antibiotic resistance risks in coastal waters
A new global database brings together information on disease-causing microorganisms, antibiotic resistance genes, and virulence factors in coastal waters, offering a practical tool for assessing biological risks in estuaries and other nearshore environments.

NewsAntibiotic-tolerant bacteria rely on a hidden survival strategy
Scientists have uncovered how S. pneumoniae adapts to antibiotic exposure and immune pressures. Their findings reveal that changes in RNA regulation enable bacteria to enter a state of antibiotic tolerance.

NewsMultidisciplinary framework bridges earth science and environmental engineering to combat waterborne pathogens
Waterborne pathogens remain a leading cause of infectious disease globally, responsible for 24% of all deaths and over 10 million fatalities each year. Source: Zheng-Yang Huo, et al. Graphic Abstract Despite decades of progress in water treatment, conventional approaches have struggled to keep pace with the evolving ...

NewsResearchers find CRISPR-Cas coordinates layered bacterial defense network
A new study reveals that CRISPR-Cas plays a broader role in bacterial immunity. Rather than acting alone like a solitary sniper shooting at phages, it also serves as a central command center, directing a network of diverse innate immune systems.

NewsNew research identifies potential early indicator of Johne’s disease exposure in calves
New research has found that antibodies against Johne’s disease can be detected in the blood of newborn calves after they have received colostrum from their mothers. Antibody measurements could provide a way to determine when calves are first exposed to the disease.
