NewsLouse-borne relapsing fever: How the pathogen evades the immune system
A research team has now identified and characterized five closely related proteins that are crucial for the survival of Borrelia recurrentis in the human body. These so-called Chi proteins appear to have evolved from a common ancestor and are therefore considered homologous.

NewsGLP-1s may alleviate depression in mice through the microbiome
Some people taking GLP-1 drugs for diabetes and obesity experience mental health benefits. In a mouse model study, researchers report that these improvements appear to result from gut microbiome changes that lead to an abundance of a microbe strain known to have a favorable effect on neurons related to stress.

NewsWhen motion prevents order: scientists probe self-organising activity
Pack enough string-like objects together, and they will begin to align with one another. But replace the strings with worms or bacteria living in your gut, and this self-organisation becomes much more difficult. Researchers have demonstrated that activity can fundamentally alter one of the most important phase transitions in soft matter physics.

NewsScientists probe antiviral molecules in bacteria that target bacteriophages
Researchers have examined the antiviral molecule daunorubicin, produced by Streptomycetes, and decoded its mode of operation against viruses. They now describe this mechanism, which primarily targets a specific group of viruses – namely bacteriophages.

NewsChina’s psittacosis knowledge gap: A scoping review calls for coordinated action
Psittacosis—a bacterial pneumonia transmitted from birds to humans—is experiencing a notable resurgence in China. A new review presents a sobering picture: psittacosis is epidemiologically substantive, clinically serious, and chronically underserved by institutional resources and public health infrastructure.

NewsTwo types of biochar help alfalfa survive salty soils
A new study shows that carefully designed biochar can guide plant metabolism and reshape beneficial microbial communities around the roots to help reduce stress from saline-alkali soil.

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.

NewsNew antibiotic attacks bacteria in never-before-seen way
Scientists have discovered a new antibiotic that works in a never-before-seen way and may be the next frontliner in the fight against drug-resistant superbugs.

NewsThe evolution of individual species can shape entire species communities
A study demonstrated that the evolution of a single species can alter the composition of an entire species community. The study monitored a microbial community composed of 23 bacterial species for four years. Researchers analysed the community’s species composition and changes in bacterial genomes.

NewsStudy finds common infection does not increase risk of recurrent preterm birth
A new study has found that the common sexually transmitted infection, Mycoplasma genitalium, also known as MGen, does not appear to increase the risk of recurrent preterm birth. Earlier research suggested that certain Mycoplasma species might contribute to preterm labor, but those studies were limited.

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.

NewsFrom pest to useful tool: How wax moth larvae can help reduce animal testing in research
A new study indicates greater wax moth larvae show great potential as a robust and ethically acceptable in vivo model for studying pathogenic bacteria.

NewsAntibiotics drive resistance in waterways - even after they break down
Antibiotics continue to drive resistance to bacteria, even after they are broken down in wastewater treatment plants and discharged into rivers and seas, new research published on World Oceans Day has shown for the first time.

NewsDigital model guides cleaner biohydrogen production
A research team has developed an enzyme-aware digital model that explains why hydrogen-producing microbes often struggle to grow fast and generate hydrogen efficiently at the same time. The study reveals how limited enzyme resources shape the balance between cell growth, by-product formation, and hydrogen generation.

NewsShiga-producing E. coli infections are becoming more resistant to antibiotics
A new study indicates resistance to antimicrobial agents is rising among human infections with Shiga toxin–producing Escherichia coli bacteria.

NewsResearch team awarded NIH grant to study early immune determinants of human tuberculosis infection
A research team was awarded a 5-year, $3.8 million grant to study early immune responses in the lung and how they influence tuberculosis infection outcomes. The program focuses on how lung immune cells called macrophages influence the earliest stages of tuberculosis infection.

NewsHow are chloroplasts communicating with the nucleus? Bacterial enzymes show the way
By utilizing bacterial enzymes that cleave heme molecules at different sites, researchers have developed a method to dissect phytochrome-dependent light and heme retrograde signaling pathways in plants, which have previously been difficult to discuss separately.

NewsDrug-resistant bacteria found in homes from sewage overflow
A new study shows that sewage overflows in homes can expose people to bacteria that can make them sick, including antibiotic-resistant and multidrug resistant bacteria which can make infections difficult to treat.

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.

NewsFever and chills can make respiratory diseases more contagious
A new study reveals that when the difference between body temperature and the ambient temperature is greater, the clouds of particles generated by coughing or sneezing disperse more and maintain a higher concentration.
