Building better DNA editors: Retrons raise the bar for gene research
Within bacterial cells, specialized immune systems known as retrons fend off viral attacks. But that's not all they can do. Scientists, including Seth Shipman, Ph.D., at Gladstone Institutes, have shown that retrons also ...

Do bacteria age?
Any organism that lives, grows and reproduces must also age. People often think of aging in the physical sense—gray hair, slowed movements and wrinkles—but aging fundamentally occurs on a molecular level, inside of cells.
