NewsMarine viruses use ‘hijacked’ genes to take over bacteria and exploit their energy systems
Marine viruses deploy a sophisticated Trojan horse maneuver that enables them to dismantle the energy systems of ocean bacteria and use the breakdown products for self-replication, according to a new study.

NewsGut microbiome connects obesity to cancer, impacting public health
A new review highlights growing scientific evidence that imbalances in gut bacteria can influence metabolism, trigger inflammation, and increase cancer risk. These insights offer new possibilities for disease prevention, early detection, and personalized health care.

NewsHospital bug jumps from lungs to gut, raising sepsis risk
A hospital-acquired bacterium that causes serious infections can move from the lungs to the gut inside the same patient, raising the risk of life-threatening sepsis, new research reveals.

NewsFive new phages discovered in university’s Botanical Gardens
Five new bacteriophages have recently been discovered in the ponds of Lund University’s Botanical Gardens. Phages thrive wherever bacteria are found, which often means ponds and watercourses that are rich in organic material.

NewsEmerging human and canine leptospirosis in New South Wales shows separate transmission pathways
A geospatial study of leptospirosis outbreaks in New South Wales suggests that humans and dogs may have largely independent transmission pathways.

NewsNew collection of bacteria-eating viruses can tackle hospital superbug
An international team of researchers have comprehensively catalogued a new collection of bacteria-eating viruses called phages sourced, in part, from hospital wastewater. The phages have been shown to be effective against different strains of Klebsiella pneumoniae.

NewsNew super pest combines broad spectrum of microbes
Researchers investigating what role the reed leafhopper’s microbial flora might have played in its rapid spread as a pest found it hosts at least seven species of bacteria and appears to be completely dependent on three of these species, which inhabit specific organs.

NewsSnakebites: COVID vaccine tech could limit venom damage
The same technology used in COVID-19 vaccines could help prevent muscle damage from snakebites, according to scientists who say it could be even more useful for other conditions where toxins cause harm gradually, such as blocking harmful toxins produced by bacteria during infections.

NewsNatural, non-engineered bacterium selectively targets colorectal cancer
Scientists have demonstrated that the marine bacterium Photobacterium angustum exhibits potent antitumor effects against colorectal cancer. The natural bacterium requires no genetic modification yet selectively accumulates in tumor tissues with minimal impact on healthy organs.

NewsTeam discovers cyanobacteria activate different genes by day and by night
By analyzing gene expression in the cyanobacterium Nostoc punctiforme, scientists discovered that during daylight, the cells focus on metabolism. But under cover of darkness, they turn to the control of genome repair and activate various genetic elements.

NewsResearchers subvert plasmids to combat antibiotic resistance
Scientists have devised a way to track the evolution and spread of antibiotic resistance in individual bacteria by measuring competition among plasmids. Plasmids evolve independently but also help drive bacterial evolution, including the development of resistance to antimicrobial compounds. They are the primary way that resistance can jump from one type of bacteria to another.

NewsToxic gut bacteria may drive ulcerative colitis by killing protective immune cells
A toxin-secreting gut bacterium may fuel ulcerative colitis by killing protective immune cells that maintain intestinal homeostasis, according to a new study. The findings suggest potential for new treatment strategies.

NewsMicrobial nano-selenium breakthrough boosts tea quality and safety
Scientists developing selenium-enriched tea have identified a powerful selenium-reducing bacterium, Raoultella ornithinolytica S-1, capable of converting inorganic selenium into selenium nanoparticles (SeNPs) while simultaneously promoting plant growth.

NewsNew study finds higher levels of antimicrobial resistance (AMR) in surface water during winter
A new study has found that the levels of antimicrobial resistance (AMR) present in surface water increase during winter. Flooding, sewer overflows and agricultural run-off all contribute to a cocktail of pollutants that can increase AMR genes in surface water, potentially turning regular bugs into ‘superbugs’.

NewsDiphtheria toxin fragment harnessed to fuse lipid vesicles at neutral pH
Researchers have discovered a novel way to fuse lipid vesicles at neutral pH. By harnessing a fragment of the diphtheria toxin, the team achieved vesicle membrane fusion without the need for pre-treatment or harsh conditions, opening the door to new applications.

NewsScientists develop world’s first modular co-culture platform for the one-pot production of rainbow-colored bacterial cellulose
The team engineered Komagataeibacter xylinus for bacterial cellulose synthesis and Escherichia coli for natural colorant overproduction. A co-culture of these engineered strains enabled the in situ coloration of bacterial cellulose.

NewsScientists use computer model to improve hospitals’ ability to limit spread of drug-resistant infections
The computer model improves on traditional methods like contact tracing by inferring asymptomatic carriers in the spread of antibiotic-resistant infections.

NewsDrinking water people believe to be safe and clean often contain potentially dangerous bacteria
A study in Guatemala found the sources of drinking water people believe to be safe and clean often contain potentially dangerous bacteria. Bottled water sold in large refillable jugs was the most frequently contaminated with coliform bacteria – an indicator of fecal contamination.

NewsStudy unveils structure, identification and characterization of the RibD-enolase complex in Francisella
A study aiming to identify anti-tularemia drug targets determined the atomic structure and identified its components of the native RibD-enolase protein complex in Francisella novicida.

NewsNew nanogel technology destroys drug-resistant bacteria in hours
A novel technology shows over 99.9% effectiveness against Pseudomonas aeruginosa (P. aeruginosa). It centres on a heteromultivalent nanogel: a flexible particle made by crosslinking polymers and adding sugar residues (galactose and fucose) alongside antimicrobial peptides.
