Bacteria prompt a new look at the dynamics of collective behavior

A study led by Princeton researchers has revealed how bacteria navigate obstacles to ensure cohesive group movement. The finding has implications for understanding the general processes of collective migration, from cancer ...

A never-before-seen way bacteria infect cells

Zombie bites and airborne transmission are some of the fictional and all-too-real methods that pathogens like bacteria and viruses use to infect new hosts. Biologists from San Diego State University have identified a new ...

Human gut bacteria have sex to share vitamin B12

Your gut bacteria need vitamin B12 just as much as you do. Though DNA is usually passed from parent to child, new research shows gut bacteria transfer genes through "sex" in order to take their vitamins.

New spheres of knowledge on the origin of life

The shape of a cell affects its physical and chemical properties. Different cell types have developed different shapes to enable effective functioning. But what shape were the very first cells, as life began to evolve?

Bacterial genome is regulated by an ancient molecule

We are all collections of cells, each cell containing the instructions—our DNA—to become any other cell. What differentiates a heart cell from a skin cell from a brain cell is the expression—or silencing—of genes.
