NewsResearch forecasts global antimicrobial resistance threats for the next two decades
New research has analysed antimicrobial resistance (AMR) on a global scale to predict how resistance patterns could evolve by the year 2050, identifying around 210 resistance traits that could pose the greatest future risk.

NewsStudy reveals 45 new toxins produced by bacteria associated with foodborne infections
Researchers have discovered 45 new toxins produced by Salmonella bacteria, some of which are associated with foodborne infections. The study shows that these substances primarily act in the competition among microorganisms for space and resources.

NewsA gut bacteria molecule may calm intestinal inflammation by turning down cellular energy
A new study suggests enterobactin, a molecule produced by gut bacteria, could offer a new pathway for treating inflammatory bowel disease.

NewsHow exercise fights implant infections: Muscle hormone “musclin” unveiled as a key defender
A new study reveals how the exercise-induced myokine musclin reprograms macrophage metabolism to clear dead cells and treat periprosthetic joint infections.

NewsGut bacteria linked to osteoporosis risk in primary hyperparathyroidism
Researchers studying primary hyperparathyroidism, a common endocrine disorder characterized by excessive secretion of parathyroid hormone, have identified Bifidobacterium longum as a potential microbial driver of bone loss through immune-mediated mechanisms.

NewsCapacity of certain unicellular organisms to stick together may be key to animal evolution
Researchers have found that after feeding a specific bacteria to a certain unicellular relative of animals, the single cells began to stick to one another, revealing a possible mode by which our ancestors began to evolve into animals billions of years ago.

NewsResearchers investigate the underlying causes of post-treatment Lyme disease syndrome
With an estimated one million Americans afflicted with post-treatment Lyme disease syndrome, newly funded research seeks to determine whether the condition is triggered by a persistent autoimmune response, and if a test can be devised to pinpoint who is more likely to develop it.

NewsStudy deploys DNA to track infectious bacteria from raccoons via rivers to humans
The emerging infectious bacterium Escherichia albertii has caused outbreaks of severe food poisoning and hospitalized people through contaminated water and foods, such as salad ingredients. A new study suggests a pathway by which invasive raccoons transmit infections to humans.

NewsThousands of young people to be offered two-dose MenB vaccine ahead of autumn
Thousands of young people across England will get protection against meningococcal B disease (MenB) through a one-off vaccination programme launching ahead of the 2026 academic year.

NewsGenomic analysis redefines the origin of eukaryotic cells
A new genetics study using the MareNostrum supercomputer redefines the genetic origin of the last common ancestor of all eukaryotes, highlighting the contribution of novel bacteria and even giant viruses in the emergence of eukaryotic cells.

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.
