My interview with @nature.com

“A new direction in our work is to understand the microbial inhabitants of the atmosphere. Is it just a dispersal mechanism for dormant cells, or does it harbour active microbes that grow and divide?”

Cryptic genetic variation shapes the fate of gene duplicates in a protein interaction network - Nature Communications

Over time, paralogous genes accumulate changes in their sequences that do not affect their function, which is called cryptic variation. Using paralogous myosins, this study shows how cryptic variation...
