Infected bacteria fight back with ‘hidden’ genes that halt cell growth, slow viral spread
Researchers have uncovered a surprising way bacteria defend themselves: when a bacterium is infected, bacterial enzymes that copy genetic information from RNA into DNA synthesize genes whose protein products help shut down cell growth.

Marine algae use massive enzymes of unprecedented size to biosynthesize fish-killing toxins
Marine algae Prymnesium parvum use massive enzymes dubbed PKZILLAs – some of the largest proteins ever to be identified in nature – to make large and complex prymnesin neurotoxins responsible for mass fish kills during harmful algal blooms worldwide.

Multi-omics strategy reveals how insect parasite fungus ameliorates sepsis-associated acute kidney injury
Scientists have found that Cordyceps sinensis significantly ameliorates renal injury and inflammation in sepsis-associated acute kidney injury (S-AKI) by regulating mitochondrial energy metabolism and macrophage polarization.

Saliva indicates severity of recurrent respiratory infections in children
A saliva test can more accurately indicate the severity of recurrent respiratory infections in children than the standard blood test. If saliva contains too few broadly protective antibodies, a child is more likely to suffer from pneumonia episodes.

Fungi elude antifungal treatments by restructuring cell walls
A new multi-institutional study has characterized how fungi adapt to restructure their cell walls, effectively thwarting current antifungal medications. This new information opens opportunities to devise more effective use of antifungal drugs.

Scientists get to the bottom of COVID’s worst pediatric complication
Scientists investigating multisystem inflammatory syndrome in children (MIS-C) found their immune systems had latched onto a part of the coronavirus that closely resembles a protein found in their bodies, launching an attack on their own tissues.

Keto diet reduces friendly gut bacteria and raises cholesterol levels
The ketogenic diet raises cholesterol levels, particularly in small and medium sized LDL particles, and alters gut microbiome composition, decreasing beneficial bacteria often found in probiotics, a new study reveals.

Superbugs spread to family members of recently hospitalized patients
Family members of patients recently discharged from hospital may have a higher risk of getting an antibiotic-resistant infection, even if the patient was not diagnosed with the same infection, suggesting hospitals play a role in community spread of resistant bacteria.
