Genetics + Genomics

Scientists turned cutting-edge CRISPR and single-cell sequencing tools on human cytomegalovirus, which affects around half of all adults, illuminating interactions between viral and host genes and adding to the list of possible drug targets. 

A new screening method from the labs of Whitehead Institute Member Jonathan Weissman, Britt Adamson at Princeton University, and Editas Medicine provides a deeper look at how cells repair DNA damage. The method could help researchers assess the action of new gene editing methods. 

Some of the most important tools in researchers’ toolkits are the model organisms they use to study biological questions. How do researchers decide which species, out of the millions that exist, to develop as models? Whitehead Institute researchers have had a hand in establishing and promoting the use of several model organisms over the years.

The new system streamlines the process of fermenting plant sugar to fuel by helping yeast survive industrial toxins.

Researchers in Whitehead Institute Director Ruth Lehmann’s lab have discovered that swarm cells, a previously enigmatic cell type, help primordial germ cells time their transformation during development so that the ovary can successfully assemble for egg production. 

A paper from the lab of Whitehead Institute Member Rudolf Jaenisch suggests that the genetic material of SARS-CoV-2 can integrate into the host cell genome and be expressed in some patient-derived tissues.

Melissa Pamula is a postdoc in Whitehead Institute Director Ruth Lehmann’s lab studying the cells that make and become eggs and sperm. We sat down with Melissa to learn more about her and her experiences in and out of the lab.
