With the help of directed evolution, scientists inch closer to developing viral vectors that can cross the human blood-brain barrier to deliver gene therapy.

Scientists have genetically modified isolated microbes for decades. Now, using CRISPR, they intend to target entire microbiomes.

Biofilms are home to millions of microbes, but disrupting their interactions could produce more effective antibiotics.

Bacteria cooperate to benefit the collective, but cheaters can rig the system. How is the balance maintained?

A device dubbed the “mother machine” enables real-time observation of mutagenesis in single bacterial cells.  

The finding that a bacterium within a bacterium within an animal cell cooperates with the host on a biosynthetic pathway suggests the endosymbiont is, practically speaking, an organelle.

The versatility of geometric shapes made from the nucleic acid are proving useful in a wide variety of fields from molecular computation to biology to medicine.

Bacteria-infecting viruses affect the composition and behavior of microbes in the mammalian gut—and perhaps influence human biology.
