In the 1920s, Soviet biologist Ilya Ivanov tried to create a "Humanzee," a human-chimpanzee hybrid. All experiments in Africa and the Soviet Union failed. Modern genetics confirmed this is impossible: humans have 23 chromosome pairs, chimpanzees 24.

In 2004, physicist Andre Geim discovered graphene by peeling scotch tape off graphite during a casual Friday evening experiment. This "dream nanomaterial"—200 times stronger than steel and 100 times more electrically conductive than copper—earned him the Nobel Prize in 2010.

The "photic sneeze reflex," nicknamed ACHOO syndrome, causes people to sneeze when suddenly exposed to bright light. It's surprisingly common—affecting 18–35% of Americans and about 25% of the Japanese population.

Pure water is an insulator. Electricity passes through water not because of the water itself, but because of dissolved ions. Tap water conducts electricity well because it contains ions like chlorine from disinfection.
