SCIENTISTS have a happy habit of stumbling upon crazy facts. You could even say it's their job.
But it's hard for people with regular IQs - us, for example - to keep up with every amazing discovery.
So we've compiled a list with ten of the more surprising facts uncovered by science in recent years.
1. PLANTS HAVE FAMILIES
They have no memory, but plants can recognise their close relatives and work alongside them. Plants grow less aggressively when surrounded by "family members", helping each other instead of competing fiercely as they would with "strangers".
2. YOUR BODY IS A POWER SOURCE
The average human produces about 100 watts of power while resting, and that number can rise to 2000 watts during intense exercise. Some of this energy is wasted, escaping the body as heat. Scientists have been working on a way to harness that energy for a while, and they're making some strides, so stay tuned.
3. MALE SEAHORSES CAN GET PREGNANT
Seahorse sex is the ultimate role reversal. The males have "brood pouches", where females deposit their eggs before leaving the guys to give birth. We reckon a few human men would benefit from a pregnancy or two as well.
4. A HANDSHAKE TRANSFERS MORE GERMS THAN A KISS
Noble boyfriends and girlfriends, take note. There's no point in refusing to kiss your partner when you have a cold unless you keep your hands away from them as well. "People avoid kissing each other when they have a cold, but in fact they are more likely to pass on an infection by shaking someone's hand," hygiene expert Professor Sally Bloomfield says.
5. THIS JELLYFISH IS IMMORTAL
If the Turritopsis nutricula is injured, it turns itself into a blob and starts a process called transdifferentiation. The creature's cells revert to their earliest form and grow again, effectively regenerating. The jellyfish can be killed by predators, but otherwise it won't die.
6. WE'RE CLOSELY RELATED TO MUSHROOMS
Humans share a common ancestor with practically everything, but it turns out we're more closely related to mushrooms than we used to think. Think of the difference between sharing a grandfather and sharing a great-great-grandfather. Surprisingly, mushrooms are more closely related to humans than they are to plants.
7. THE UNIVERSE IS 13.82 BILLION YEARS OLD
Say you live to the ripe old age of 100. Multiply that lifespan by 138,200,000 and you'll get the age of the universe, give or take a hundred million years. Makes you feel pretty young, doesn't it? Incidentally, Earth is a spritely 4.54 billion years old.
8. YOUR HAIR CAN SUPPORT 12 TONNES
Well, not if you're half bald. But a full head of hair can hold the weight of two elephants combined. We'd advise against trying to test that theory at home though. Stick to a Rapunzel re-enactment.
9. CHICKENS DON'T NEED THEIR HEADS
Don't take this the wrong way. Chickens would much prefer to keep their heads. But one famous chook managed to live for 18 months after having his lopped off. "Mike the Headless Chicken" retained enough of his brain stem to keep going, and he ended up touring the United States. What a star.
10. OUR SUN WILL BECOME A HUGE DIAMOND
The blandly named star BPM 37093, otherwise known as "Lucy", puts every engagement ring on the planet to shame. It's basically a massive diamond of 10 billion trillion trillion carats, according to the BBC. Scientists expect our sun to crystallise into a diamond itself in about seven billion years.
