An intricate set of processes govern how cells know where to go and what to become during development. In this article, learn how Whitehead Institute researchers are investigating the various biological mechanisms that serve as the architects of life forms.

Multicellular organisms evolved over millennia into a dazzling array of differently adapted creatures. With each generation, tiny worms, lavishly plumed birds, and even humans must create themselves anew from a single cell. To do so, they require a plan. This multimedia story collection explores the myriad of ways in which an organism's development is orchestrated. Click the links below to read and watch.

A new Whitehead Institute study investigates the role a family of proteins called Sestrins plays in sensing the presence of the essential amino acid leucine, as well as adapting to its absence. The presence of Sestrin allows fruit flies to choose foods rich in leucine over foods without the nutrient.

Haley Licon is a postdoc in Whitehead Institute Member Sebastian Lourido’s lab studying how the parasite Toxoplasma gondii switches between stages during infection. We sat down with Haley to learn more about her and her experiences in and out of the lab.
