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.

Researchers propose a new framework for how satellite DNA, sometimes called “genomic junk,” is essential in the organization of chromosomes in cells. They suggest this quickly-evolving DNA is one reason different species are unable to successfully interbreed.

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.

Researchers at Whitehead Institute propose a new model for how the stem cells in aquatic worms called planarians commit to a specific fate. Instead of a long, slow process that occurs over many generations, the researchers suggest that the transition from “blank” stem cells to specialized cells could happen in a single division.

Ann Boija is a senior researcher in Whitehead Institute Member Richard (Rick) Young’s lab studying the role of cellular structures called condensates in gene regulation. We sat down with Boija to learn more about her and her experiences in and out of the lab.

If we imagine the cell as an orchestra, with many musicians who each have a small part to play, then what conducts all of these musicians and keeps them organized and harmonized as they play a symphony?

Whitehead Institute scientists investigate germ cells — the cells that never cease to exist
