A simple adjustment to a powerful gene-editing tool may be able to improve its specificity. In a report receiving advance online publication in Nature Biotechnology, Massachusetts General Hospital (MGH) investigators describe how adjusting the length of the the guide RNA (gRNA) component of the synthetic enzymes called CRISPR-Cas RNA-guided nucleases (RGNs) can substantially reduce the occurrence of DNA mutations at sites other than the intended target, a limitation the team had previously...

Single cell analysis captures a genomic phenomenon that fuels the complexity and diversity of living things A Ludwig Cancer Research study has uncovered a phenomenon that alters prevailing views of how the genome is expressed to make and sustain the life of mammals. Published in the journal Science, the paper helps explain why genetically identical animals are sometimes so different in their biology and appearance, and why some inherited disorders caused by a shared set of aberrant genes...
