Changes in DNA and gene function are the engines that drive evolution. These seemingly small modifications in an organism’s evolutionary journey ultimately dictate its fate —  deciding which traits will be safeguarded and transmitted through generations, and which new traits will emerge. Whitehead Institute researchers are studying how organisms sharing a common ancestor develop unique traits over time, diverging from one another. These traits — encoded in the genes — impact their chances of survival and reproduction.

Whitehead Institute Member Jonathan Weissman and colleagues used large-scale systematic genetic screens to identify the molecules and pathways that populate the mitochondrial surface with important and diverse signaling proteins. They deciphered the logic by which the cell ensures the proper delivery of these proteins. These findings may have important implications for understanding the impact on health and disease when these processes go awry.

In an increasingly interconnected and complex world, collaboration is more important than ever for progress in science. By coming together, scientists can share knowledge and ideas to solve complex problems, learn new skills, and advance their careers. Researchers at Whitehead Institute recognize the importance of collaboration when taking on big challenges in science.

To avoid widespread famine and malnutrition, the world must double current food production by 2050, and do so in the face of climate-driven pressures. That is why a key thrust of the Whitehead Initiative on Biology, Health, and Climate Change focuses on plant seeds, the source of more than two-thirds of calories currently consumed globally.

A new study reveals that the protein MTCH2, which is essential in a variety of cellular processes, is responsible for shuttling various other proteins into the membrane of mitochondria. The finding could have implications for cancer treatments and provides insight into a variety of MTCH2-linked conditions.

Single-cell RNA sequencing allows scientists to capture unique gene expression information in dozens, hundreds, or even hundreds of thousands of cells. Learn how Whitehead Institute scientists are applying this technology to a variety of model organisms to uncover a rich diversity of cells.
