NewsNew technique reveals marine microbes’ outsized role in carbon cycle
A small fraction of marine microorganisms are responsible for most of the consumption of oxygen and release of carbon dioxide in the ocean, new research suggests.

NewsLiquid-coated air filter inspired by carnivorous plant can improve early capture of airborne pathogens
Researchers have designed a new liquid-coated air filter that allows for improved early detection and analysis of airborne bacteria and viruses, including the one that causes COVID-19.

NewsResearchers create simulation that paves way for electrogenetic toggle switch model
A team of scientists has developed a computer simulation that would allow them to create an electronic toggle switch, expanding what a synthetic gene network designed for biocomputations can do.

NewsToxic bacteria find floating homes on microfibres in the Mediterranean Sea
Almost 200 species of bacteria have colonized microfibres in the Mediterranean Sea, including one that causes food poisoning in humans, according to a new study.

NewsNew evidence that drug resistant bacteria can travel from gut to lung
A new study from the Department of Biology, University of Oxford, has found the first direct evidence of antibiotic resistant bacteria migrating from a patient’s gut microbiome to the lungs.

CareersAMI internship leads Zoe down path of antimicrobial resistance
Zoe Dunphy undertook a lab internship in 2020 in Trinity College Dublin’s microbiology department, funded by an AMI Summer Studentship Grant. She reveals how that experience has developed her work on AMR.

NewsHospitals are riskier than farms when it comes to superbug transmission - but beware your pet
A deadly drug resistant bacterium that rivals MRSA is found in livestock, pets and the wider environment, but is rarely transmitted to humans through this route, scientists have found.

NewsResearch team develops alginate hydrogels that can support bacterial cell growth
Researchers at the University of Illinois Urbana-Champaign have developed modified alginate hydrogels that can endure the growth of bacteria, allowing them to synthesize important enzymes.

NewsAntibiotic resistant microbes in gut make C difficile more infectious
Scientists have found that Enterococcus – an antibiotic-resistant, opportunistic pathogen – works together with Clostridioides difficile in the human gut, reshaping and enhancing the metabolic environment in the gut so that C. difficile can thrive.

NewsBacteria behind biblical disease have potential to regenerate livers
Scientists have discovered that the bacterium that causes leprosy can reprogramme cells to increase the size of a liver in adult animals without causing damage, scarring or tumours.

NewsDuplicate genes play key role in formation of legumes’ nitrogen fixing structures
Researchers have found that a duplication of the genes plays a key role in the processes governing the formation of symbiotic structures between nitrogen-fixing bacteria and leguminous plants.

NewsProbiotic ‘backpacks’ could treat inflammatory bowel diseases
Researchers have devised specialised nano-particles that can neutralise molecules linked to inflammatory bowel disease (IBD), and can be attached to beneficial probiotic bacteria targeting the gut.
-
NewsGut parasites could aid the spread of respiratory bugs in rabbits
Researchers have found that co-infection with one or more gut parasites increases shedding of Bordetella bacterium and could increase onward transmission.
-
NewsViruses deploy CRISPR system to thwart bacterial defences
Researchers have shown that viruses engineered with a CRISPR-Cas system can thwart bacterial defenses and make selective changes to a targeted bacterium – even when other bacteria are in close proximity.

NewsGold mine bacterium can clean arsenic-polluted wastewater within days
A bacterium found in a former gold mine in Poland can clean up industrial wastewater polluted with arsenic, selenium and metals within days, researchers have discovered.

NewsGram-negative bacteria build outer membrane into body armour-like structure
A new study has shed light on how Gram-negative bacteria like E. coli construct their outer membrane to resemble body armour, which has far-reaching implications for the development of antibiotics.
-
NewsGull droppings undermine efforts to control spread of colistin-resistance genes
Gull droppings at beaches in the Porto region of Portugal are riddled with bacteria that are resistant to the ‘last-resort’ antibiotic colistin, undermining efforts in the livestock sector to reduce colistin-resistance, according to a paper published in Environmental Microbiology, an Applied Microbiology International publication. Researchers at the ...

NewsBacteria can be programmed as fast-responding pollution sensors
Scientists and engineers at Rice University have engineered living bioelectronic sensors based on bacteria that can quickly sense and report on the presence of a variety of contaminants.

NewsNew method offers real time monitoring of gut microbiome
Researchers have found a simple and innovative way to examine the intestinal bacteria of the human small intestine to show how they support the digestive process by reacting dynamically to the human nutritional status.
