Parasites, Mercury, and the Universe's Fate

This chapter explores three captivating scientific topics, starting with the parasite Entamoeba histolytica that successfully evades the immune system by masquerading as a white blood cell. It also discusses the significant 70% drop in atmospheric mercury levels since 2000 and the skepticism surrounding its causes. Finally, the chapter considers a revised timeline for the universe's heat death, suggesting it may occur much sooner than previously anticipated, all while weighing the validity of these scientific claims.
