NewsMicrobiome insights found in faeces help predict infections in liver transplant patients
In a new study, researchers at the University of Chicago were able to predict postoperative infections in liver transplant patients by analyzing molecules in their poop. Their analysis represents a key leap forward in exploring the connection between the gut microbiome — the bacteria that inhabit the human body — ...

NewsScientists reveal rare enzyme role change with bacterial defense system assembly
A never-before-seen phenomenon in a protein: alone, the enzyme processes DNA and RNA but, when bound to another protein as part of a defense system, interacts with a completely different type of compound to help bacteria commit suicide.
