While the CRISPR-Cas9 gene editing system has become the poster child for innovation in synthetic biology, it has some major limitations. CRISPR-Cas9 can be programmed to find and cut specific pieces of DNA, but editing the ...

Unparalleled inventory of the human gut ecosystem

An international team of scientists has collated all known bacterial genomes from the human gut microbiome into a single large database, allowing researchers to explore the links between bacterial genes and proteins, and ...

Exploring the role of gut bacteria in digestion

They congregate in the environments that suit them best; some prefer the dry, desert-like conditions of our forearms while others thrive in the Amazon-style humidity of our feet.

Biomedical engineers teach bacteria to count

Biomedical engineers at Boston University have taught bacteria how to count. Professor James J. Collins and colleagues have wired a new sequence of genes that allow the microbes to count discrete events, opening the door ...
