In order for researchers to understand the biology of living organisms, they must consider what is happening across the size scale. Interactions between molecules drive interactions between cells that affect traits and behaviors. Experiences and decisions made by the organism can lead to changes at the cellular and molecular level. In order to understand the full picture, Whitehead Institute researchers study everything from molecules to cells to whole organisms.

Whitehead Institute Director and Member Ruth Lehmann and colleagues have found that membrane-less compartments, called condensates, within germ cells not only store but also play an active role in the translation of specific mRNAs. This finding uncovers the possibility that other RNA-protein condensates can actively regulate protein production.

The Li lab recreates early developmental events in the Petri dish to study the building blocks of life. But this unique approach to biology carries implications that stretch past embryonic development.
