Science facilities are terran structures responsible for conducting advanced research into new weapons and defensive technologies. During the Great War, it was rumored that protoss technology was researched in such structures, a study that continued well into the End War.
The science facility researches the upgrades for science vessels, and allows research of tier 2 and 3 armor and weapon upgrades.
Reduces shield and energy to 0 for all enemy or allied units within the blast radius. Particularly useful against protoss units and buildings.

Reduces the hit points of biological units near the targeted unit (and the targeted unit itself if it is biological) by 250 over 30 seconds. Mechanical units are immune, but biological units passing near an irradiated mechanical unit will still be affected.
The science facility can add a physics lab to itself, enabling production of battlecruisers and researching abilities and upgrades for them. This prevents the science facility from building a covert ops.

Science facilities appear in the mission Infested in Heart of the Swarm. Placing a creep tumor next to them infests the structure as a bonus objective, each one granting a bonus Kerrigan level.
Science facilities appear in Brothers in Arms in Legacy of the Void where they are under attack by Moebius Corps. Destroying all enemies near them frees units to support the player and their allies, and earns five solarite as a bonus objective.
In Left 2 Die, the science facility is the responsible for unlocking new units and structures (or upgrades for them) researched using biomass. On the map, it possesses a radar ability similar to the sensor tower.
