Scientists are different from most resources, as they are returned to the player after use and are never lost.
The player starts the game with one Scientist. New Scientists can be bought for Diamonds and one additional Scientist can be earned by researching the Doppelganger technology in the [[Black Hole#Dark Matter Institute| Dark Matter Institute]]. There is no limit to how many Scientists a player can have, but each consecutive purchase of a Scientist increases its price.
Scientists are required to produce resources, evolve Bacteria, irradiate Evolved Bacteria and Bacteria colonies,
and to clean the lab after Bacteria mutation.After researching the Quantum Leap technology at the Dark Matter Institute, each idle Scientist also doubles the player's [[BPS]].
Before Version 1.0.0, Scientists were called Laborants.
