Can you solve the virus riddle?
by Mark Frauenfelder from on (#2JE08)
"Your research team has found a prehistoric virus preserved in the permafrost and isolated it for study. After a late night working, you're just closing up the lab when a sudden earthquake hits and breaks all the sample vials. Will you be able to destroy the virus before the vents open and unleash a deadly airborne plague?"
A fun Ted-Ed puzzle by Lisa Winer.
