Scientists have uncovered how DnaA, the master key to DNA replication, opens the door to bacterial growth. This breakthroughpaves the way for new antibiotics to combat the rising tide of antibiotic ...

E. coli divides faster than it can replicate its genome, while simultaneously expressing its genes. Scientists recently revealed the intricate molecular coordination that makes this possible. “It’s as ...

Colibactin is a powerful toxin produced by Escherichia coli and other bacteria living in the human gut. This highly unstable bacterial product causes mutations in DNA that have been linked to ...

An analysis of the bones and teeth of ancient mammoths (Mammuthus) has identified some of the microorganisms that lived in the animals’ mouths and bodies more than one million years ago. The study, ...

Transposons are critical drivers of bacterial evolution that have been studied for many decades and have been the subject of Nobel Prize winning research. Now, researchers from Cornell University have ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American DNA is important stuff. It's present in all ...

The microbial toxin colibactin has just the right shape to snuggle up to DNA — but its embrace is unfortunately more cancerous than cozy. Colibactin is produced by bacteria in the gut and causes ...

Pushing into a new chapter of technologically advanced biological sensors, scientists from the University of California San Diego and their colleagues in Australia have engineered bacteria that can ...
