NewsNew study reveals cyanobacteria may help spread antibiotic resistance in estuarine ecosystems
Scientists have discovered that cyanobacteria may play a major role in spreading antibiotic resistance genes in coastal environments. The findings highlight a previously overlooked link between natural nutrient cycling and the global challenge of antibiotic resistance.

NewsTaxiing through the gut: Formic acid in the microbiome
Scientists have found that the gut bacterium Blautia luti produces formic acid (formate) instead of carbon dioxide (CO₂) and hydrogen, with hydrogen bound to CO₂. In this case, formic acid is the electron taxi, allowing the energetically costly production of hydrogen to be bypassed.

NewsLarge-scale study analyses the impact of climate on Legionnaires’ disease in Catalonia
A study has analysed the relationship between climatic conditions, the presence of Legionella in water systems and cases of Legionnaires’ disease in Catalonia. The link between these different factors highlights the need to adapt prevention and surveillance strategies in the context of climate change.

NewsNew study reveals a minimalist bacterial defense that disrupts viral assembly
Researchers describe how a single protein named Rip1 recognizes bacteriophages, the viruses that infect bacteria, and cause infected bacteria to die prematurely, thereby ending the chain of transmission.

NewsA mint idea becomes a game changer for medical devices
Researchers have developed a high‑performance coating made from peppermint essential oil that can be applied to the surfaces of many commonly used medical devices, offering a safer way to protect patients from infection and inflammation.

NewsGreen chemistry: Friendly bacteria can unlock hidden metabolic pathways in plant cell cultures
Co-culturing plant cells with harmless bacteria can expand the diversity of obtainable plant-derived compounds for pharmaceuticals, cosmetics, and agrochemicals, a new study shows.
-
NewsSugar molecules point to a new weapon against drug-resistant bacteria
Researchers have developed a powerful new way to target deadly, drug-resistant bacteria by designing antibodies that recognise a sugar found only on bacterial cells – an advance that could underpin a new generation of immunotherapies for multidrug resistant hospital-acquired infections.

NewsGut microbe–derived butyrate activates immune cells to enhance vaccine efficacy
Researchers have uncovered a new mechanism showing how butyrate—a short-chain fatty acid produced by gut commensal bacteria—enhances T follicular helper (Tfh) cell activity to promote antibody production and strengthen mucosal vaccine efficacy.

NewsPlants influence the composition and function of their surrounding microbiome to suit their needs
An investigation into plant–microbe interactions at the genetic, metabolic and physiological levels revealed that 203 bacterial gene sequences were strongly shaped by the host plant, for example through their metabolic products. One bacterial genus was found to enhance root development even in nitrogen-limited soils.

NewsClinical data gaps keeping life-saving antibiotics from children
Antibiotics that could treat severe infections in babies and children aren’t accessible due to a lack of data around safety and dosage. Of 12 antibiotics recommended for serious bloodstream infections caused by a harmful, Gram-negative bacteria, only six were licensed in children aged under 12 and just three in babies.

NewsScientists fight superbugs with nets, light switches - and egg white
A new gel could combat resistant bacteria in wounds and around implant sites, while also supporting healing. The hydrogel, which is inspired by natural immune defences, has produced highly promising results in animal models.

NewsRisk for Lyme disease in Ohio is equal to Connecticut, study shows
The risk for being bitten by a tick infected with bacteria that cause Lyme disease is as high in Ohio as it is for those living in Northeast states that have dealt with Lyme disease for over 50 years, according to a new study.

NewsGenes from corn’s wild ancestor change soil microbial community, improve sustainability
Corn bred with genes from wild relatives can reshape soil microbial communities and reduce nitrogen loss — with no yield reduction, according to new research. It’s the first time corn’s genetic makeup has been linked with inhibition of nitrifying and denitrifying bacteria.

NewsCommon bacteria discovered in the eye linked to cognitive decline
Chlamydia pneumoniae can linger in the eye and brain for years and may aggravate Alzheimer’s disease. Research suggests this bacterium can amplify Alzheimer’s disease and points to potential interventions including inflammation-limiting therapies and early antibiotic treatment.

NewsHow brick-building bacteria react to toxic chemical in Martian soil
Researchers investigated how bacteria that can mould Martian soil into brick-like structures fare in the presence of perchlorate, a toxic chlorine-containing chemical discovered in Martian soil. It slows down bacterial growth - but surprisingly leads to the formation of stronger bricks.
-
NewsHow bacteria learned to target numerous cell types, revealed
A new study shows how bacteria adapted a virus-derived injection system to recognize and attach to many different types of cells. By identifying thousands of rapidly evolving receptor-binding proteins, the researchers explain how these systems can be retargeted in nature by swapping the part that binds to cells.

NewsGenetic system makes worker cells more resilient producers of nanostructures
Researchers report the development of a new genetic regulatory system to improve cell viability during the production of gas vesicles.

NewsPediatric investigation study reports significant shifts in post-COVID respiratory infection trends in children
To explore how the pandemic changed respiratory infection trends in children, researchers examined data from 73,096 pediatric patients hospitalized with acute respiratory tract infections in two coastal cities in eastern China with similar climates.

NewsOne of Earth’s most abundant organisms is surprisingly fragile
A group of ocean bacteria long considered perfectly adapted to life in nutrient-poor waters may be more vulnerable to environmental change than scientists realized. The bacteria, known as SAR11, dominate surface seawater worldwide and can make up as much as 40% of marine bacterial cells.

NewsNew research finds crosstalk inside cells helps pathogens evade drugs
Biologists have uncovered a new mode of communication inside cells that helps bacterial pathogens learn how to evade drugs. Their findings describe how these mechanisms drive antimicrobial resistance in Listeria monocytogenes, the foodborne bacteria that causes listeriosis.
