NewsRings of power – how bacteria use circadian clocks to colonise their world
A new study reveals how bacteria rely on circadian clocks to control the spread of their multi-cellular colonies.

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.

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.

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.

NewsMovement of “forever chemicals” through the Great Lakes
New analysis of 42 years worth of biological records from the Great Lakes, unveils how per- and polyfluoroalkyl substances (PFAS) or “forever chemicals” have moved across the region, contaminating a variety of wildlife.

FeaturesUnder the microscope: extremophiles of the Earth
Extremophiles are microbial organisms that live in extreme environments normally considered uninhabitable. Over the past few decades, extremophiles have been discovered in increasingly bizarre and unexpected environments around the globe, including within acid lakes, plastic recycling centres and even in radioactive sites such as Chernobyl.

NewsAlluring yeast species could yield new mosquito traps to combat malaria
An orange-colored yeast species isolated from a Baltimore sidewalk several years ago could be the basis of eco-friendly mosquito traps that reduce malaria transmission, according to a new study.

NewsBacteria organise themselves into diverse, coordinated communities in order to travel across large distances
A new study examined the migration of microbial communities over long distances, and found bacteria migrate not as solitary swimmers, but in diverse, coordinated communities that also contain viruses and “hitchhiking” microbes that cannot swim on their own.

NewsQ&A: Meet Letters in Applied Microbiology Junior Reviewer Md. Ekramul Karim
We caught up with Md Ekramul Karim, a Ph.D. candidate at the University of Houston, who is one of the newest Junior Reviewers with Letters in Applied Microbiology.

NewsDentistry researchers testing oral bacteria transplants to cure bad breath
To rebalance the oral microbiome and cure chronic halitosis, researchers are embarking on a first-of-its-kind experiment. These clinical trials transplant bacteria and other microbes from healthy donors into patients with halitosis. If successful, the healthy microbiota will crowd out the bad and patients’ bad breath will improve.

NewsResearcher investigates how a bioengineered peptide can break through harmful bacterial ‘fortresses’ and curb severe infections
A researcher is refining a powerful therapy for drug-resistant bacteria that pierces the gooey coating that anchors and protects such germs from the drugs we take to kill them. She has found that an antimicrobial peptide naturally found in cows weakens the biofilm defenses of Klebsiella pneumoniae bacteria and destroys it.

NewsWhy antibiotics fail against a common dental implant disease
A study of peri-implantitis found that bacteria corrode implants, causing them to shed microscopic titanium particles into the surrounding tissue. Those particles hijack the immune cells sent to clear the infection and lock them into a state of inflammation that destroys the jawbone they are supposed to protect.

NewsHidden small RNA determines if cholera bacterium can infect humans
Scientists have uncovered what gives Vibrio cholerae, the bacterium that causes cholera, the ability to colonize the human gut. They found that a small RNA embedded within another gene controls where cholera thrives, a discovery that could improve prediction and prevention strategies.

NewsHow bacteria ‘chat’ their way to carbon-neutral water treatment
Global climate goals demand that wastewater treatment plants transform their operations. A new review reveals that quorum sensing (QS), the chemical communication system bacteria use to coordinate behavior, could be the key.

NewsWhy antibiotics may soon fail to curb the plague bacterium - and where we can find new strategies
A new review shows that while most infections caused by the Yersinia plague bacterium can currently be treated with antibiotics, concerns about rising antimicrobial resistance mean that we need to come up with new ways to disarm the bacteria instead of killing them.

NewsScientists pinpoint the changes that happen when gut bacteria invade the bloodstream
Researchers have pinpointed genotypic and phenotypic changes that take place when colonising bacteria in a patient’s gut invade and infect the bloodstream. The team aimed to determine what changes occur within bacteria in a patient’s gut that enable them to become invasive bloodstream pathogens.

NewsViruses enhance sulfamethoxazole removal in wetlands by modulating bacteria-phage interactions
A new study examines the role of viruses in sulfamethoxazole (SMX) removal in constructed wetlands. The research demonstrates that the addition of phage-concentrated solutions (PCS) enhances the degradation of SMX by enriching SMX-degrading bacteria.

NewsStudy finds blood pressure drug effective for treating antibiotic-resistant bacteria
A new study reports that a drug used to lower blood pressure could also be the basis of a promising new treatment for methicillin-resistant Staphylococcus aureus (MRSA). Candesartan cilexetil not only killed MRSA bacteria at different growth stages, but also reduced the formation of biofilms.

NewsHow microbes survive in the plastisphere
Trillions of persistent plastic particles of varying sizes are scattered throughout the world’s oceans, where they often accumulate in ocean gyres known as ‘garbage patches’. Two of these regions were the focus of research expeditions.

NewsViruses ‘eavesdrop’ on each other – but it can backfire
Viruses can “eavesdrop” on each other using chemical signals – but it can backfire for the eavesdropper, new research shows. Scientists studied chemical communication by phages, viruses that infect bacteria.
