However, when rapamycin blocks mTOR, 4E-BP1 is free to put the brakes on.

"Generally, the robot has been used to check up on patients in between when they would normally see a physician. During these visits, we ask them about how they are feeling, inspect their surgical sites to ensure they are healing properly, and answer any questions they have."
