Scientists discover ancient enzymes evolve new tricks

Plants, herbivores, and pathogens are locked in a war for survival that is hundreds of millions of years old. Rooted in place and with no way to run, plants evolved complex, chemical-producing machinery in their cells to ...

How nitrogen-fixing bacteria sense iron

Researchers at the University of East Anglia have discovered how nitrogen-fixing bacteria sense iron—an essential but deadly micronutrient.

Regulation of Pom cluster dynamics in Myxococcus xanthus

Rod-shaped bacterial cells normally divide by constriction midway along their long axis. LMU physicists have developed a theoretical model to explain how Myxococcus xanthus localizes the plane of division to mid-cell.

MicroRNAs regulate the formation of mitochondria in cells

Muscles require a large amount of energy to function. This is provided primarily by mitochondria in cells that consume a lot of energy. We therefore find more of these powerhouses of the cell in muscle cells than in other ...
