So, I got the psionic virus. But this time, no research option. How do I get it?
I understand the cure requires a space station with a medical facility.

How do I check which world are infected or cured? Edit: found it: on the planet screen, check if there is any "icon" to the left of your flag, in the upper right corner. Although you get a message when a planet get infected, you get none if it is cured.
