Science has many uses for donated bodies.
When you donate your body to science, it can be used as a crash test dummy, a cadaver for medical training, specimen for forensic research, or a donor for organ transplants.
Marie Curie is the only person to win Nobel prizes in two different sciences.
Marie Curie is the only scientist in history to be awarded Nobel prizes in two different categories: she was awarded her first Nobel Prize in Physics in 1903 for her work on radiation, and a Nobel Prize in Chemistry in 2011 for her discovery and work on radium and polonium.
Banana peels have almost no friction.
Banana peels have felled many cartoon characters, Mario Kart players, and average people alike. However, what makes it so slippery in the first place? To answer this, four Japanese scientists measured the amount of friction between a shoe, a banana skin and the floor. Turns out, the friction coefficient was at an almost nonexistent 0.07 – walking with the banana peel was 6 times slippier than normal friction between a shoe and the floor.
More than half of your body is bacteria.
Human cells make up only 43% of the body’s total cell count. The rest are bacteria, viruses, and fungi – the greatest amount of these microbes are in our bowels.
The human eye has a 576 megapixel resolution.
When our eyes send visual signals to the brain, it has enough capacity to process images in 576 megapixels. However, we only see at about 150dpi, since that is more than enough visual stimuli for us to see objects.
Laika was the first animal in space.
Two months after Sputnik 1, the Soviet Union launched its second spacecraft, Sputnik 2 with its first passenger: a small dog named Laika. With this voyage, Laika became the first animal to orbit Earth, but died 7 hours into orbit.
2 is the only even prime number.
A prime number is a special number that is only divisible by 1 and itself. 2 is a prime number that is divisible by 1 and 2. The remaining even numbers cannot be prime numbers as they are always divisible by 2. Don’t believe us? Try it yourself!
Feldspar is the most common mineral on Earth.
Feldspar is a group of tectosilicate minerals that form rocks and make up 41% of the Earth’s crust.
Hot water freezes more quickly than cold water.
The principle of hot liquids freezing faster than cold ones is called the Mpemba effect. This phenomenon was discovered by a Tanzanian student when he realized that hot ice cream mix freezes faster than a cold mix in the early 1960s. Although it has been attempted, no one has successfully explained why hot water would freeze faster than cold water.
It takes 6 minutes for brain cells to react to alcohol.
A 2009 study proved that drinking alcohol can alter brain cells in just 6 minutes. During an experiment, they found that alcohol consumption decreased the levels of creatine and choline in the brain. This could explain the long-term brain damage observed in alcoholics.
Most dinosaurs are known from just a single tooth or bone.
Given that dinosaurs were alive 65 million years ago, complete fossils are extremely rare. Instead, archaeologists study traces such as loose teeth, bones, tracks, or dung in order to identify the dinosaurs we read about in books now.
Nuclear power plants are safer work environments compared to offices.
So far, there has been no record of worker casualties in the entire 50-year history of nuclear power in the U.S.
Helium changes our voice because of its density.
Helium is much less dense than oxygen. Typically, we breathe in nitrogen and oxygen. Since helium is less dense than oxygen, the sound of our voice travels faster through our vocal cords. Therefore, helium makes our voice sound weird because the sound is traveling over two times faster than usual.
Tooth enamel is stronger than bones.
The lining of our teeth is the hardest substance in the human body.
The father of electricity lived his childhood in poverty.
Michael Faraday had to work at the age of 13 to sustain himself, since his father was sickly and could not do so. However, he still went on to contribute to what we know about electricity today.
Humans haven't stop evolving.
If you look at the evolution of life, you’d think we’ve come a long way from the ape-like Homo erectus. However, this is not our final form, yet. Researchers tracking eight million mutations found that defective genes – such as ones that influence disease – are slowly being filtered out of our DNA.
Scientists weigh planets through its gravitational pull.
You may wonder how we have all these measurements for planets when it seems impossible to measure objects in space, much less objects as massive as the planets. However, things changed with Lord Henry Cavendish’s experiment in 1797. Through his findings, scientists now calculate a planet’s weight by the time it takes for objects to orbit the planet and the distance of those objects from the planet.
Cavendish set up an experiment with two 150 kg lead balls (planets) and two smaller spheres (moons). He measured the gravitational pull between these elements. Through his experiment, Cavendish discovered the missing piece of Newton’s gravitational puzzle, which was the value of G – the amount that relates the gravitational force between two bodies to their masses and distance. With the new value of G, Cavendish was also the first man to attempt weighing a planet. He used Newton’s equation with the value of G to calculate that the Earth’s mass is six billion trillion tonnes.
People used to believe the Earth was the center of the universe.
For a long time, people believed in geocentrism, which described the Earth as the center of the universe. It was only until 1543 that Nicolaus Copernicus proposed the concept of heliocentrism, or the sun being the center of the solar system, or the universe. Some years later, Galileo confirmed the theory.
50% of museum items are mislabeled.
About half of all the natural history specimens held in the world’s greatest institutions are wrongly labeled, according to experts from Oxford University and the Royal Botanic Garden. This is troubling since the whole point of museums is to preserve accurate records of the past. Errors in labeling specimens could potentially erase a species’ or peoples’ records from existence. Additionally, revising a museum label would cost around US$750. Given the amount of mislabelled specimen, how much would that end up costing?
Fast food restaurant ice is often dirtier than toilet water.
You may want to think twice about munching on that ice. In a 2016 study conducted in the U.K., major fast-food chains were revealed to have fecal bacteria in their ice. Starbucks was also among the list. It was (hopefully) not due to a case of tampering, but a lack of maintenance for their ice machines.
Swimmers sweat underwater.
Sweating is the biological function of the body to cool itself. During intense workouts, the body will perspire even in the water. However, it’s barely noticeable even to the swimmers themselves since the water washes the sweat off.
It is scientifically possible to die from drinking too much water.
It’s important to stay hydrated to keep our bodies functioning well. However, too much water can also be fatal. When a dehydrated person drinks too much water without the accompanying electrolytes, they can die from water intoxication and hyponatremia. In fact, forced water intake is even a known torture method.
Pure hydrogen can kill you.
Pure hydrogen gas acts as a chemical asphyxiant. If you walk into a room with no oxygen, you won’t be able to breathe, right? It’s one of the no-brainer science facts.
One of the greatest paleontologists did not go to school.
Mary Anning contributed greatly to paleontology, finding many major marine fossils throughout her life. However, Anning did not have the best upbringing. She was born in a family of 10 siblings, but only 2 reached adulthood, including her. She did not attend formal schooling, and yet she became one of the great names in science. How’s that for badass science facts?
The ocean contains 20 million pounds of gold.
Gold in the ocean waters is so dilute that it would be like looking for sugar grains in a gallon of unstirred coffee. Gold ores can also be found in the depths of the seafloor, but these deposits are encased layers upon layers of rock. Currently, there is no efficient way to retrieve these gold deposits from the ocean.
A 5th-grader accidentally created a new molecule in 2012.
During a class activity, 10-year-old Clara Lazen presented her teacher with a randomly-constructed molecule diagram. Instead of dismissing it, Mr. Kenneth Boer took a photo and sent it to a chemist for analysis. Turns out, it was a new, explosive molecule called Tetranitratoxycarbon.
Female animals can sometimes reject sperm.
For different species such as chickens, some animals practice sperm dumping to reject the sperm of mates they don’t like.

Scientists created a synthetic uterus for lamb.
On April 26, 2017, Physicians at the Children’s Hospital of Philadelphia created a uterus “biobag” capable of sustaining premature fetal lambs. After 105 days of development (the equivalent of 22 days for humans), the lambs were extracted from their mothers and sealed in the bags. Surprisingly, they developed in the synthetic wombs and even survived long after.
Thomas Edison electrocuted an elephant to death to prove a point.
To prove that his direct current was safer than Nikola Tesla’s alternating current, Thomas Edison conducted a public experiment on an elephant. In 1903, Edison filmed an elephant getting fried by alternating current in Coney Island. Luna Park Zoo offered Topsy the Asian elephant for the experiment, since she had killed 3 handlers throughout the years. Topsy wouldn’t be Edison’s only victim, since he recorded other animals being electrocuted as well.
Johann Conrad Dippel created Dippel’s oil and claimed it was elixir.
Johann Conrad Dippel was a scientist in the late 1600s who created Dippel’s oil: a stew made of animal bones and hide. He claimed his concoction could extend the lifespan of those who drink it. Definitely one of the science facts that are hard to stomach.
Isaac Newton believes the world will end after 2060.
Based on a Bible passage, Newton believed that the apocalypse will come some time after the year 2060.
Leucippus was the first scientist who proposed atoms.
