Split gene-editing tool offers greater precision

To make a gene-editing tool more precise and easier to control, Rice University engineers split it into two pieces that only come back together when a third small molecule is added.

Weaker transcription factors are better when they work together

Bioengineers can tailor the genomes of cells to create "cellular therapies" that fight disease, but they have found it difficult to design specialized activating proteins called transcription factors that can throw the switch ...
