In an ideal world, science experiments can save lives and make the world a better place. Medical programs help us understand diseases and their causes and symptoms; thereby, researchers can figure out the most appropriate forms of practical and manageable side effects.
Successful studies lead to betterment in human (and animals) health. But we don’t live in an ideal world. Sometimes, in the name of science, researchers are motivated to discover a breakthrough and come up with inventions to the point where ethics never get in the way.
As a result, they devise questionable experiments in which subjects’ well-being is not even taken into consideration in the first place. When scientists violate ethical boundaries in their practices, horrific consequences happen.
What follows are some of the most horrible science experiments where the subjects were exposed to dangerous, in many cases life-threatening, and unnatural procedures with long-term adverse effects on their health and behaviors.
10 The Mouse With A Human Ear
A rodent with a human ear grown on its back certainly looks like something drawn on a cartoonist scrapbook, except this one is now a fictional illustration but a photograph of an actual mouse.
Known as the Vacanti Mouse, the animal was, in fact, a live rodent part of a study that began in 1989. The mouse was never genetically modified; its ear was made of sterile, biodegradable mold placed under the rodent’s skin.
Once inside, the mold was seeded with cartilage cells from a cow. After several months, the mold degraded, and the ear-like structure became the mouse’s natural organ.
9 The Soviet Surgeon And His Two-Headed Dog
Vladimir Demikhov was a Soviet scientist born just after the Russian Revolution. He was an accomplished doctor credited with many groundbreaking experiments that would later play a vital role in human organ transplantation studies.
One of the most notable was his successful attempt to graft two dogs together. Demikhov sewed the forearms and head of a small dog named Shavka to a larger dog called Brodyaga.
The procedure involved severing Shavka’s spinal column, aorta, and jugular vein, then linking her circulatory system to Brodyaga’s body. The two heads could eat and drink separately.
