I believe that chapter 18 had the most compelling issue from the book thus far. In this chapter, a few of the revolutionary events that involved HeLa cells were discussed in good detail. First, culture cells were dying in the lab or quickly becoming cancerous. In one experiment, HeLa cells were sent into space with a Discoverer satellite to determine their propensity to continue living. They not only survived the trip, but also continued to divide at an accelerated rate. Around this time, other scientists began to report that their cell cultures were behaving normally, despite producing different byproducts when they consulted. This evoked a contamination within the cell cultures with the cause and extent unknown to the scientist. The most
