NewsTracking batch culture pinpoints moment when ‘silent’ biosynthetic gene clusters kick in
A team of scientists has mapped the times during a batch culture when core biosynthetic genes surged into action, showing that bursts of biosynthetic gene cluster (BGC) transcriptional activity correlated with surges in net production rates per cell of known natural compounds.

NewsWar in Ukraine pushes highly contagious infectious diseases to alarming levels
New research being presented at this year’s ECCMID reveals an extremely worrying picture of rising infectious disease cases and falling levels of childhood vaccination and case detection in Kharkiv, the scene of some of the most intense combat in 2022.

NewsResearchers find regulatory mechanism that keeps cancer-causing bacteria in check
Researchers have discovered an important mechanism that may have profound implications for how we prevent colorectal cancer.
-
NewsBacterial signalling across biofilm affected by surface structure
Researchers who examined how different structures affect biofilm growth and quoring signalling by the bacteria in the presence of antibiotics found structure does have an effect on QS in some strains of the bacteria.

NewsSARS-CoV-2 infection speeds up the progression of dementia, new study shows
All subtypes of dementia, irrespective of patients’ previous dementia types, behaved like rapidly progressive dementia following COVID-19.
-
NewsChemical warfare against competitors drives colonization success in plant microbiota
Two natural chemicals - produced by a single bacterium - not only affect the structural organization of the root microbiota, but also act in concert to give the bacterium an advantage in colonizing and dominating the root niche.
-
NewsNew shape-shifting antibiotics could fight deadly infections
Scientists have created a new weapon against these drug-resistant superbugs—an antibiotic that can shape-shift by rearranging its atoms.
-
NewsMosquito saliva can weaken body’s defenses against deadly dengue viruses
The saliva of mosquitoes infected with dengue viruses contains a substance that thwarts the human immune system and makes it easier for people to become infected with these potentially deadly viruses, new research reveals.

NewsAltered gut microbes may be linked to childhood ADHD susceptibility
New research suggests that the microbial composition of the gut may affect a child’s susceptibility to attention-deficit/hyperactivity disorder (ADHD).

NewsHuman case of tick-borne encephalitis virus acquired in the UK for first time
The first confirmed domestically-acquired case of tick-borne encephalitis virus (TBEV) has been identified in a man who was bitten by ticks in Yorkshire, and another probable human case has been detected in the Loch Earn area of Scotland.
-
NewsBats disturbed by humans are more frequently infected with coronaviruses
Bats in human-dominated ecosystems have a higher prevalence of coronaviruses, increasing the possibility that these could be transmitted to humans.
-
News‘Hangry’ bacteria pump out toxins, unlike their identical but well-fed colleagues
New study shows that genetically identical cells within a bacterial community have different functions, with some members behaving more docile and others producing the very toxins that make us ill.
-
NewsRising temperatures alter ‘missing link’ of microbial processes, putting northern peatlands at risk
Study finds that microbial processes in peatlands fall out of sync at higher temperatures, with Sphagnum moss cover plummeting as the mercury rises.
-
NewsScientists reveal how getting physical can tackle a key hurdle in synthetic biology
A team of scientists may have solved one of the biggest hurdles standing in the way of synthetic biology - the difficulty of transferring the resulting large DNA molecules into bacterial host cells.
-
NewsA healthy microbiome may prevent deadly infections in critically ill people
A study finds that gut microbiota and systemic immunity work together as a dynamic “metasystem,” in which problems with gut microbes and immune system dysfunction are associated with significantly increased rates of hospital-acquired infections.
-
NewsEngineered E. coli delivers therapeutic nanobodies to the gut
A genetically modified beneficial strain of bacteria blocks intestinal inflammation in a preclinical model of inflammatory bowel disease and has the potential to treat intestinal-based diseases.

NewsVaginal microbiome does not influence babies’ gut microbiome
New research is challenging a longstanding assumption that a baby’s gut microbiome is primarily shaped by their mother’s vaginal microbiome, while shedding new light on the factors that do influence its development.
