Science Facts You Never Learned in School Part: 2

Science Facts You Never Learned in School Part 2:

Bananas are radioactive :

For one of our strangest science facts, bananas contain potassium, and since potassium decays, that makes them slightly radioactive. But it’s nothing you need to worry about. You’d need to eat 10,000,000 bananas at once to die of radiation poisoning, Forbes reports.

Hot water freezes faster than cold water

This fact seems counterintuitive, but it’s called the Mpemba effect, after a Tanzanian student named Erasto Mpemba who told his teacher than a hot mixture of ice cream froze faster than a cold one. Scientists now believe this is because the velocities of water particles have a specific disposition while they’re hot that allows them to freeze more readily. If proven correct, this finding could also have implications in daily life, like cooling down electronic devices.

Cold water heats up faster than hot water

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

Humans are related to fungi

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 percent 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. Don’t miss these mysteries about the human body no one can solve.
