Welcome back to Cell Crunch, a newsletter about all things genetic engineering and synthetic biology. I’ve returned from hiatus and intend to keep this newsletter running far into the future.
This is the first edition of Cell Crunch Index. Every Monday, notable papers from the last week are compiled. Research explainers, Q&As and other journalism will be sent out on other weekdays. Thanks for reading.
