Mind-blowing science facts
Epigenetics is the study of how genes can be switched on or off without changing the underlying DNA code. Diet, stress, and environment can all leave chemical 'marks' on genes that can even be passed to future generations.
Fermat's Last Theorem stated that no three whole numbers can satisfy a particular equation involving cubes or higher powers. It took 357 years and hundreds of pages of advanced mathematics before Andrew Wiles finally proved it in 1995.
A chameleon's tongue accelerates faster than a Formula 1 race car. It can shoot out to twice the length of the chameleon's body in about a hundredth of a second.
The Moon is slowly drifting away from Earth at a rate of about 3.8 centimeters per year. Billions of years ago, the Moon was much closer and appeared far larger in the sky.
The spongy tissue inside your bones called bone marrow produces about two million new red blood cells every single second. Red blood cells only live for about 120 days before being broken down and recycled.
Bioluminescence — the ability to produce light using a chemical reaction — has evolved independently more than 50 times across different groups of animals. Over 76 percent of deep-sea creatures can produce their own light.
Dry ice is frozen carbon dioxide that skips the liquid phase entirely and goes straight from solid to gas — a process called sublimation. This makes it ideal for keeping things cold without any messy melting.
Einstein's famous equation E=mc² shows that mass and energy are two forms of the same thing. Even a tiny amount of mass contains an enormous amount of energy — one gram of matter contains as much energy as an atomic bomb.
Your brain contains about 86 billion neurons, each forming thousands of connections. Signals travel between neurons at speeds of up to 120 meters per second — about as fast as a Formula 1 car.
A day on Mars lasts 24 hours and 37 minutes — almost the same as Earth's 24-hour day. This is one reason scientists consider Mars the most Earth-like planet in our solar system.
