NewsLandmark study reveals ‘megacluster’ of bacterial genes behind arsenal of potent antibiotics
A newly discovered “megacluster” of genes in Streptomyces bacteria produces four new natural product antibiotics that work together to stop rival bacteria.

NewsBiofilm “scaffolds” protect bacterium responsible for food poisoning from antibiotics
Bacillus cereus, which is responsible for human infections and food poisoning, builds organized communities that act as a ‘shield’ against antibiotics, a new study reveals.

NewsSoil pH regulates the symbiosis between stink bugs and gut bacteria
A new study shows soil pH regulates the symbiosis between stink bugs and gut bacteria, revealing alternative strategies to pesticides in agricultural pest control.
-
NewsThe miracle microbes that could save crops from impact of rising sea levels
A new study reveals a previously unknown mechanism by which microbes help plants – including maize, tomato and rapeseed - survive in harsh environments, with major implications for agriculture worldwide.

NewsMicrobes rewrite the rules of cancer immunotherapy by triggering immunogenic cell death
A new study reveals that microbiota and their metabolites can effectively reprogram immunogenic cell death (ICD), a unique form of cell death that activates the body‘s immune system against tumors, transforming immunologically “cold” therapy-resistant tumors into “hot” responsive ones.

NewsLarge-scale microbiome study identifies robust colorectal cancer signature
Researchers have identified a robust microbial signature associated with colorectal cancer. The study also analysed 906 intestinal tissue samples to compare stool-based microbiome signals with microbes found directly in tumour tissue.

NewsA soil bacterium turns electricity and carbon dioxide into acetate
A new study shows that a soil bacterium can directly reduce Fe(III) minerals, exchange electrons with electrodes, and use electrode-derived electrons to convert carbon dioxide into acetate under autotrophic conditions.

NewsVeterinary review warns antibiotic resistance threatens vision in pets
A new review warns sight-threatening antibiotic-resistant eye infections are becoming a significant threat to vision in dogs, cats, and horses with multidrug-resistant bacteria becoming more common in referral veterinary settings.

NewsThe early immune clues that determine who develops TB
An early view of the immune response to bacteria in the lungs provides clues as to why some people keep TB in check, while others develop disease, suggesting new ways to intervene earlier and stop TB.

NewsNative litter jump-starts microbial recovery in mine soils
By applying litter collected from nearby native woodland to rehabilitated mine land, a study has shown increases in microbial diversity, enrichment of carbon- and nitrogen-cycling microorganisms, and stronger biochemical potential for soil organic matter decomposition and nitrogen mobilization.
-
NewsGlobal port microbiomes reveal hidden biosecurity signals
By analyzing more than 16 million 16S rRNA gene sequences from 1,045 port water samples collected in 23 cities across five continents, a study has found clear biogeographic patterns, a core set of dominant bacterial genera, and widespread potential pathogens.

NewsOrdinary enzyme evolves into a ‘control switch’ revealing a new weak spot in tuberculosis
A protein that acts as a ‘control switch,’ preventing Mycobacterium tuberculosis from accessing the energy sources it needs to survive, has been identified by researchers. The discovery points to a specific vulnerability in the bacterium that could be targeted by new TB treatments.

NewsResearchers aim to autonomously eliminate plant-killing bacteria from hydroponic farming systems
Three researchers have received a nearly $600,000 grant from the U.S. Department of Agriculture to develop a system that can autonomously detect and remove crop-killing microbes from hydroponic farms before they cause damage to plants.

NewsHow cyanobacteria developed photosynthetic membranes over the course of evolution
New research analyses hundreds of cyanobacterial genomes to understand the origin of thylakoids, the internal membranes involved in photosynthesis.
-
NewsSoil bacteria reveal hidden arsenic stress in brick kilns
Researchers collected soils from a shut-down brick kiln area. As arsenic levels increased, bacterial richness and diversity declined, while arsenic-tolerant groups became more abundant. The study also found that bacteria strengthened stress-response pathways and upregulated arsenic-resistance genes.

NewsTracking melanoidins to improve food-waste biogas recovery
Higher pretreatment temperatures in food-waste biogas recovery can promote Maillard reactions, generating melanoidins. A study shows that melanoidins increase with hydrothermal temperature and inhibit methane production by disrupting methanogenic microbial communities.
-
NewsCaught in the act: A gene jumps into the void
Self-splicing introns are a special group of jumping genes. It is more difficult for a gene to jump into another cell or another species. Until now, it had been assumed that, for this to happen, the jumping genes travelled as ‘hitchhiker’ in the genomes of plasmids or viruses, but researchers have made a surprising observation.

NewsUrgent hot tub health warning as Britain prepares to sizzle
As Britain prepares to sizzle with temperatures expected to reach 37°C in some areas over the next four days, water experts are warning that a potentially deadly disease can thrive in hot tubs, pools and other domestic water devices.
-
NewsReservoir of drug-resistant germs IDed in national surveillance collaboration
Researchers who screened more than 2,000 samples across 42 states say there is a rapidly evolving, plasmid-driven epidemic of community-associated multidrug resistant Klebsiella pneumoniae across the United States.

NewsSweeping product analysis reveals path to more effective probiotic supplements
Probiotic supplements in drugstores contain microbes sold for specific health purposes despite limited understanding of their connections to their marketed use. But scientists have assembled computer models that could lead to more effective products to shape our microbiomes to improve health.
