NewsGenetics: Oldest-known evidence of plague outbreaks in prehistoric communities
Plague outbreaks dating back to around 5,500 years ago documented in hunter-gatherer communities from southeast Siberia are described in a paper. The findings, based on an analysis of ancient DNA, may be the oldest known evidence of the plague and could shed light on its origins.

NewsMicrobes frozen in ancient rubbish heaps help reconstruct ancient Greenlanders’ farms, seal hunts, and toilets
The microbiome of ancient middens in Greenland sheds new light on the daily life of Paleo-Inuit and old Norse communities. Researchers say the middens in the cold Arctic acted like long-term natural experiments, with human- and animal-associated bacterial signals remaining detectable many centuries later.

NewsThe hidden danger of cat lick – a case report with reconstruction
Capnocytophaga canimorsus is a bacterium found in the mouths of dogs and cats. It can cause severe sepsis, and in some cases leads to purpura fulminans (PF), a condition that triggers rapid tissue necrosis.

NewsRNA barcoding approach reveals previously unknown virus-host relationships
Researchers have uncovered previously unknown relationships between bacteriophages and their bacterial hosts. They found a previously unreported group of bacterial hosts for the well-studied bacteriophage P1 and examine how subtle changes in viral structure influence which microbes a phage can target.

NewsRice husk biochar catalyst breaks down antibiotic pollutant in minutes
A new biochar supported cobalt oxide catalyst rapidly removes levofloxacin from water while revealing a key reaction mechanism for cleaner wastewater treatment.

NewsStudy reveals how bacteria assemble their envelope
Researchers have discovered a key process for how the outer membrane of gram-negative bacteria attaches to the cell wall, advancing the understanding of how these bacteria frequently manifest resistance to antibiotics.

NewsEffects of polystyrene nanoplastics and organophosphorus flame retardants on salamander gut-liver axis
New research reveals the effects of polystyrene nanoplastic and the organophosphorus flame retardant exposure on the gut-liver axis of salamanders.

NewsPlant viruses open new routes for gene editing
A new study has developed potyvirus-derived vectors for delivering CRISPR RNA (crRNA) guides in Lachnospiraceae bacterium ND2006 Cas12a (LbCas12a)-expressing plants, expanding virus-induced gene editing from tobacco rattle virus (TRV) to tobacco etch virus (TEV), turnip mosaic virus (TuMV), and lettuce mosaic virus (LMV).

NewsResearchers produce biodegradable bioplastic from potato starch using a modified bacterium
A new study has produced a biodegradable bioplastic from unprocessed potato starch in a single 24-hour step, establishing that the bacterium Bacillus subtilis is a robust platform of great industrial interest for producing polyhydroxybutyrate from a low-cost agricultural by-product.

NewsPathogens survive conditions on extraterrestrial locations
Microorganisms from our planet could survive on celestial bodies where water is present, such as Mars, reveals a study focusing on simulated space conditions. Our immune system reacts less effectively to pathogens that have undergone such a simulated space journey.

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.
