1. CRISPR came from basic research on bacteria. 2. Optogenetics started with a discovery in algae. 3. The GFP protein comes from jellyfish. The biggest breakthroughs all trace to scientists following their curiosity, and this is one huge reason why we must keep funding basic research!

Sex is often handled as a nuisance variable, something to hold constant or to average out. Our results say it is a variable in its own right, and one that responds to the environment. Using both sexes is not a box to tick. It is where the biology is.

Here is the part I would like people to take away. Had we studied males only, we would have written: low protein stunts growth. Females only: low protein delays puberty. Both true. Neither is the finding. The finding is the distance between them.
