From fruit flies to robots, from radio waves to moving continents—five groundbreaking discoveries show how STEM continues to shape every part of our world.
Every great leap in human history begins with a spark of curiosity. A scientist asks why, an engineer asks how, and together they redefine what’s possible. The discoveries behind the first industrial robot, the APGAR newborn test, the theory of plate tectonics, FM radio, and even the humble fruit fly experiment all prove one thing: innovation lives at the heart of STEM. These breakthroughs didn’t just change their fields—they changed the world [1].
1. The Fruit Fly That Rewrote the Rules of Life
It’s hard to imagine that one of biology’s biggest discoveries began with a jar of fruit flies. In the early 1900s, geneticist Thomas Hunt Morgan and his team at Columbia University’s “Fly Room” used these tiny insects to explore how traits are passed from one generation to the next. What they found changed science forever: genes live on chromosomes, and mutations in those genes drive evolution and diversity.
The fruit fly became a superstar of genetics. Its short life cycle and simple DNA made it the perfect model for studying everything from inherited diseases to behavior. A century later, fruit flies are still used in cutting-edge research, from understanding cancer to exploring how the brain works. Who knew such a tiny creature could open the door to understanding what makes us who we are?
2. The APGAR Score: Five Simple Steps That Save Lives
When a baby takes its first breath, there’s no room for hesitation—every second matters. In 1952, Dr. Virginia Apgar, an anesthesiologist with a passion for newborn health, devised a five-part test that would transform delivery rooms forever.
The APGAR Score, named after its creator, evaluates a newborn’s Appearance, Pulse, Grimace, Activity, and Respiration—all within a minute of birth. Doctors could now instantly assess whether a baby needed urgent care or was doing fine. Before this innovation, many newborns who could have been saved were lost simply because there was no clear way to measure distress.
More than seventy years later, the APGAR Score is still used in hospitals around the world. It’s a reminder that not every life-saving invention needs to be complex—sometimes, it’s the simplest scientific ideas that leave the greatest mark.
3. FM Radio: The Invention That Tuned the World
Imagine the 1930s: crackling static, distorted voices, and fading music on the radio. Then came engineer Edwin H. Armstrong, who refused to accept the noise. His invention of Frequency Modulation (FM) radio replaced the old amplitude system, bringing clear, rich sound to listeners everywhere.
FM radio didn’t just improve sound—it changed how people connected. It carried the voices of presidents, the songs of generations, and the news that shaped the modern world. And the technology behind it didn’t stop there. The same principles that power FM radio live on in Wi-Fi, Bluetooth, and satellite communication.
Armstrong’s fight for clarity turned into a revolution that made the world sound better—and stay more connected than ever.
4. Plate Tectonics: The Earth That Moves Beneath Us
For centuries, people believed continents were fixed. Then, in the mid-1900s, researchers at Columbia University’s Lamont-Doherty Earth Observatory started piecing together a different story. With data from seafloor mapping and magnetic field studies, they uncovered the stunning truth: Earth’s crust is alive, divided into giant plates that drift, collide, and reshape the planet.
This theory of plate tectonics became one of the greatest scientific revolutions of the 20th century. It explained earthquakes, volcanoes, and the creation of mountain ranges. It also united the fields of geology, oceanography, and geophysics into one grand framework.
Beyond its scientific impact, plate tectonics changed how we see our world—not as a static rock, but as a dynamic system in constant motion. It’s science that literally shifted the ground beneath our feet [2].
5. Unimate: The Robot That Started It All
In 1961, on a General Motors assembly line, a mechanical arm named Unimate quietly began to change the world. Created by George Devol and Joseph Engelberger, Unimate was the first industrial robot, built to handle repetitive and dangerous tasks that humans once did.
At first, people were skeptical—could machines really do human work? The answer, as history shows, was a resounding yes. Unimate’s success sparked the robotics revolution, paving the way for today’s automated factories, medical robots, and even artificial intelligence.
From the car industry to space exploration, the legacy of Unimate lives on. It wasn’t just a machine—it was the first step toward a future where humans and technology work hand in hand to build a safer, smarter world.
STEM: The Future Is Built on Discovery
Each of these stories—fruit flies, APGAR scores, FM radio, plate tectonics, and Unimate—began with a question. Why does this happen? How can this be improved? What if…? Those questions are the heartbeat of STEM.
STEM isn’t just about formulas, circuits, or experiments. It’s about solving real problems and pushing boundaries. It’s how we unravel DNA, design self-driving cars, predict earthquakes, or develop vaccines in record time. Whether it’s a scientist decoding genes, an engineer programming robots, or a geologist mapping the Earth’s future, the same spirit drives them all—curiosity and creativity powered by science.
Whether it’s in a lab, a delivery room, a radio tower, a factory, or deep beneath the Earth’s crust, one truth always stands: science leads the way.
