NewsNon-living processes in rice paddies as significant as microbes in CO2 emissions
Scientists have shown that natural processes, especially reactions involving certain reactive oxygen species, play a big role in how paddy soils release CO2.

NewsCOVID vaccination before infection strongly linked to reduced risk of developing long covid
Unvaccinated individuals are almost four times as likely to be diagnosed than those vaccinated before first infection, new research shows.

NewsSophisticated swarming: bacteria support each other across generations
When bacteria build communities, they cooperate and share nutrients across generations. Researchers have demonstrated this for the first time using a newly developed method that enables the tracking of gene expression.
-
NewsBacteria store memories and pass them on for generations
Scientists have discovered that bacteria can create something like memories about when to form strategies that can cause dangerous infections in people, such as resistance to antibiotics and bacterial swarms.
-
NewsSkin bacteria weapons can battle AMR and save lives
Researchers have found a new bacteriocin, in a very common skin bacterium. Bacteriocin inhibits the growth of antibiotic-resistant bacteria that are often the cause of disease and can be difficult to treat.

NewsLaser-powered ‘tweezers’ reveal universal mechanism viruses use to package up DNA
A study using optical tweezers reveals new insights into the roles of specific DNA motor proteins in packaging up viral genomes.
-
NewsResearchers create molecule to tackle antimicrobial resistance
Researchers at Maynooth University, working as part of an international team, have created a new molecule that could help in the fight against drug-resistant bacteria. Source: Ella Maru Studios Researchers have created a new molecule to fight drug-resistant bacteria Antimicrobial resistance (AMR) occurs when bacteria, viruses, fungi ...

NewsFeeding dogs raw meat increases the risk of antibiotic-resistant E. coli
Feeding dogs raw meat increases their risk of excreting E. coli that cannot be killed by a widely used antibiotic - ciprofloxacin - researchers have found from a study of 600 healthy pet dogs.
-
NewsBacteria lay the foundations for their descendants
Researchers investigating a sea anemone microbiome found that the bacterial community is primarily controlled by the host organism during the early stages of life, while bacteria-bacteria interactions play the lead role in subsequent development.
-
NewsResearchers develop new approaches in the fight against drug resistance in malaria
Researchers have combined the anti-malaria drug artemisinin with coumarin, which, like artemisinin, is also found in plants, and developed an auto-fluorescent compound from both bioactive substances.
-
NewsSimulation suggests mutant strains of COVID-19 emerged in response to human behavior
Using artificial intelligence technology and mathematical modeling, researchers have has revealed that human behavior, such as lockdowns and isolation measures, affect the evolution of new strains of COVID-19.
