In this video, Whitehead Member Jing-Ke Weng's graduate student, Olesya Levsh, outlines her journey to Whitehead, which personified a commitment that is at the very heart of our mission: guiding and nurturing the next generation of scientists. Weng also described how he uses a muliple "-omics" platforms -- genomics, metabolomics, proteomics, and more -- to learn about the medicinal components found in some plants.

Researchers at Whitehead Institute have uncovered how small changes in the fish Argonaute (Ago) protein, an RNA slicing protein, that happened in its lineage an estimated 300 million years ago greatly diminished the efficiency of RNAi in these animals, while another ancestral feature, in a critical pre-microRNA, was retained that enabled the microRNA to still be produced despite the fish’s impaired Ago protein.
