NewsResearchers reveal why viruses like SARS-CoV-2 can reinfect hosts and evade immune response
Using a tool called VirScan, Brigham investigators found that people produced shared antibody responses to certain regions of the virus, likely leading to selective pressure and new variants that can repeatedly escape detection by prior immunity.

NewsMicrobes that “eat together” may benefit from a shared immunological memory
A new study examines viruses that infect microbes in the deep sea and finds evidence that viruses interact with a far more diverse set of hosts than was previously thought.

NewsBumblebee superfood battles gut pathogen - and boosts queen bee production
Two new papers show that the spiny pollen from plants in the sunflower family (Asteraceae) both reduces infection of a common bee parasite by 81–94% and markedly increases the production of queen bumble bees.

NewsNewly discovered probiotic could protect Caribbean corals threatened by deadly disease
Researchers have discovered the first effective bacterial probiotic for treating and preventing stony coral tissue loss disease (SCTLD), a mysterious ailment that has devastated Florida’s coral reefs since 2014 and is rapidly spreading throughout the Caribbean.

NewsHolographic 3D microscope shows potential as red tide warning system
A new study is the first to utilize holography to characterize red tide in the field and breaks new ground for monitoring harmful algal blooms (HABs) and tackling limitations associated with current methods used to monitor these blooms.

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.

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.

NewsOcean warming intensifies viral outbreaks within corals
A groundbreaking three-year study has found that viruses may increase their attacks on the symbiotic algae within corals during marine heat waves.

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.
-
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.

NewsFirst steps driving antibiotic resistance uncovered in new study
Researchers have revealed the crucial and surprising first steps that promote resistance to ciprofloxacin, one of the most commonly prescribed antibiotics.

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.

NewsFruit fly gut remodels itself to create home for beneficial microbiome species
The digestive tract of fruit flies remodels itself to accommodate beneficial microbiome species and maintain long-term stability of the gut environment, according to new research.

NewsResearchers solve the cell structure responsible for travellers diarrhoea
Researchers have found that pili used by enterotoxigenic Escherichia coli to attach to host intestinal epithetlia are fine-tuned for their preferred microenvironment, such as the gut or the urinary tract.
