NewsThe nitroplast revealed: a nitrogen-fixing organelle in a marine alga
A nitrogen-fixing bacterial endosymbiont of marine algae is evolving into a nitrogen-fixing organelle, or nitroplast, thereby expanding a function that was thought to be exclusively carried out by prokaryotic cells to eukaryotes.

NewsScientists discover new phage resistance mechanism in phage-bacterial arms race
Sscientists exploring the complex interactions of microbes in the oral microbiome discovered a new player influencing the phage-bacterial arms race – ultrasmall bacterial parasites, called Saccharibacteria or TM7.
-
NewsScientists link certain gut bacteria to lower heart disease risk
Researchers have identified specific species of bacteria that consume cholesterol in the gut and may help lower cholesterol and heart disease risk in people.
-
NewsProcess discovered to undermine bacterial viral Salmonella infection
Study results provide a new understanding of how mammalian hosts defend against pathogenic organisms, as well as implications for better treating Salmonella.
