Instead of diffusing into the solution as they escape the needle, the viruses cling together, forming a wispy white fiber that's several centimeters long and about as strong as a strand of nylon. A gradu­ate student, Chung-Yi Chiang, fishes it out with a pair of tweezers. Then he holds it up to an ultra­violet light, and the fiber begins to glow bright red.
