For one of our strangest science facts, bananas contain potassium, and since potassium decays, that makes them slightly radioactive. But this is one of those fun science facts you don’t need to worry about. You’d need to eat 10,000,000 bananas at once to die of radiation poisoning, Forbes reports.

The researchers who investigated the cause of the Mpemba effect made this discovery as well. They unsurprisingly named the phenomenon the inverse Mpemba effect.

A 2015 study from the University of Cambridge suggests that mankind may have evolved with genes that came from plants. Because of those findings, researchers accept that about 1 per cent of the human genome could have been acquired from plants, the Telegraph reports. So all those times your corny uncle called himself a “fungi”? He was actually sort of right.

But don’t worry – we have a lot of DNA

Scientists predict that there are over 3 billion base pairs of DNA in human genes and over 25,000 genes in the human genome. An entire copy of that genome exists in each of the 10 trillion cells in the human body. If all of that DNA were lined up, it would cover the distance between Earth and the sun 100 times.

Once you master these fun science facts, don’t miss these facts about animals you have all wrong.

Diamonds are definitely the Milky Way galaxy’s best friends. Studies have examined the potential that Neptune, Uranus, Jupiter, and Saturn have to produce diamonds. The atmospheres in all four planets have such extreme pressure that they can crystalise carbon atoms and turn them into diamonds. Scientists were able to create the correct conditions in a lab to prove this occurs on Neptune and Uranus. Separately, a different group of researchers speculates that it may rain as much as 2.2 million pounds of diamonds on parts of Saturn every year – this is definitely the richest of our science facts!

If you spin a ball when you drop it, it will fly through the air as it falls. This is called the Magnus effect, and it makes playing tennis and soccer a whole lot easier.

This is called the Triple Boil, and at that temperature, water exists as a gas, a liquid, and a solid simultaneously. It requires very specific conditions to achieve, so don’t even think about trying it at home.

Those mammals would be bats. While flying squirrels can jump from trees and glide, they can’t truly fly like bats can.

Helium can also work against gravity

When helium is cooled to extreme temperatures, just a few degrees away from absolute zero (-460˚F or -273˚C), it turns into a superfluid, meaning it can flow without friction. It can climb up and over the sides of a glass. It can leak through molecule-think cracks in a container. If it starts flowing like a fountain, it will never stop.

The energy they release is the equivalent of 100-megaton atomic bombs exploding at once. It’s a good thing the Earth’s atmosphere protects us from their radiation.
