20 incredible facts that people recently tweeted
This Twitter thread may provide all the education a person needs.
- A simple question on Twitter resulted in an avalanche of mind-blowing answers.
- What else are we supposed to do with all of these stray bits of information?
- Sciency, helpful, and ridiculous — we've got 'em all.
On January 27, educator, organizer, and writer Brittany Packnett Cunningham tweeted a simple question: "What's the most random fact you know?" It turns out people know a lot of random things — the replies have been stunningly informative, amazing, and ridiculous. Here are 20 of the best facts shared:
1. A tarantula's best friend
The Colombian tarantula keeps tiny frogs as pets to protect their spider eggies from pests aka the froggies are lil spider pups— Ashley (@aNippz) January 28, 2020
So many thoughts. Interspecies slavery? Frog mills?
2. The snap
When you snap the sound comes from your finger hitting your palm— Jacqueline (@DacolinDudley) January 28, 2020
This might make you feel better if you're one of the many people incapable of doing the African Finger Snap once explained and demonstrated by Lupita Nyong'o.
Mind = blown. Did her folks do this on purpose?
4. Blood stains
If you get a drop of blood on clothing, you can remove it spitting on it. Only works if it’s your blood and your spit, though, because the enzymes need to match. Just a little bit of Professional Seamstress trivia.— Megan #wwdd? Odett (formerly Kidical Mass DC) (@Megan2Wheels) January 28, 2020
This is both amazing and cool. Custom-coded saliva just for your own personal use.
5. Not to worry
The stickers on fruit are made to be edible, just in case.— Tammy Howe (@thowe555) January 28, 2020
Are we the only ones who worry about this? Also, if you don't remove the label before washing the fruit, good luck getting it off.
6. In the event of alligator
If you are attacked by a gator and your arm is in its jaws, push, don't pull. If you can push the flap open at the back of its throat, water rushes in and it starts to drown and will open jaws, hopefully releasing you.— Anika Noni Rose (@AnikaNoniRose) January 28, 2020
7. Listen carefully
When you hum a song, the sounds comes out of your nose— Jared Palmer (@jaredpalmer) January 28, 2020
Hmmm, mmm, mmm. Whaddya know!
8. The nipple rule
most mammals have twice as many nipples as their species' average litter size (e.g. humans mostly have 1 kid at a time, but 2 nipples), this is colloquially referred to as the 'half nipple rule'— Anarcho-Bobcat (@AnarchoBob) January 28, 2020
except opossums, which for some reason have an odd number of nipples
Today is not the day nature stops being weird.
9. Your final sensation in space
If you were ever ejected into space, the last thing you’d feel before losing consciousness is the saliva on your tongue beginning to boil— Jay Kristoff (@misterkristoff) January 29, 2020
(The boiling point of liquids is lower when air pressure is lower. In vacuum, your body heat is enough to boil the spit in your mouth)
Grim, but fascinating. Let's not do this.
10. Dotting your “i”
The dot above an i is called a tittle.— ηєωт, GIFmeister General (@newtnewtriot) January 28, 2020
Because of course.
11. Not who you think they are
Roly poly bugs/pillbugs aren’t insects, they’re crustaceans, more specifically isopods, the only ones likely to be anywhere near your average North American backyard. They have giant sea-floor cousins that can grow up to a foot and a half long but look basically the same.— Megan Romer (@meganromer) January 28, 2020
12. Vegans beware
Artificial raspberry and strawberry flavoring comes from the anal glands of a beaver.— Stephanie ”I Need ❄️” Nelson (@stephanienels) January 28, 2020
While this is true, the resulting flavoring is so expensive to produce that it rarely gets used in foods. Check the label for castoreum. While you're there, keep an eye out for carmine, which is commonly used as a red coloring for food. It's made from crushed beetles.
13. Stand back or run away
Male dolphins can ejaculate as far as 10' and with such force it can kill a human if that human was foolish enough to attempt zoophilic relations with dolphin.— dr. kittens not kids (@kittensnotkids) January 28, 2020
Marine researchers must be very dedicated.
14. Or maybe just swim as fast as you can
Maybe keep your horses away from the ocean.
15. The fine grain of time
No matter how fast our brain can process information, it can never be fast enough to experience the actual present moment. Everything we experience is in the past.— bioethics402 (@jacob_dahlke) January 28, 2020
Of course "now" is a difficult concept to really comprehend. The moment you notice it, it's gone, as the tweet suggests.
This brings to mind quantum entanglement. Maybe particles don't really exist in multiple states at a time, but our ability to capture "now" is just so coarse it seems that way. Our idea of simultaneity may actually be a series of fine-grained moments rounded off into a single "now" that's large enough for us to perceive. Thus, we perceive multiple particle states as simultaneous but they're really not. Just saying.
16. Million billion
A million seconds is 12 days— Dr. M (@MaaloufMD) January 28, 2020
A billion seconds is 31 years
You've wondered, right? A perfect fact for the next conversation lull you need to fill.
17. Nuts in nature
Cashews grow on the bottom of a cashew apple. The apple is too perishable to export, so we only ever see the nuts. pic.twitter.com/ScAXAKNk6g— Drew Barth (@drewbarth) January 28, 2020
Also, we only see the nuts because some of the discarded parts of the plant are toxic.
18. Orange carrots
Oh, another:— Lynne Up North 🕷️ (@AndOrNorLyn) January 28, 2020
Carrots are orange because of a political statement.
Originally carrots came in multiple colors, including white, yellow, and purple, but orange ones were selectively bred by the Dutch as support for William of Orange, who led the the struggle for Dutch independence.
Censored vegetables, for goodness' sake.
19. Angular numbers?
The numbers we use today are based on drawings done by Phoenician merchants. Many of them were illiterate, so they added angles to a straight line and counted them instead. This picture explains it nicely: pic.twitter.com/iM51BGMGrq— Damski (@TuftyBall) January 29, 2020
Some researchers are skeptical about this origin story, especially when it comes to the symbol for zero.
20. How long you’ll remember all this
Within one hour, people will forget an average of 50 percent of info presented; 24 hours, an average of 70 percent of new info;and within a week, an average of 90 percent of it.— 2019Families2Investigate MLK/X/JFK Deaths (@jjconceptsinc) January 28, 2020
What was the first fact on this list?
Emotional intelligence is a skill sought by many employers. Here's how to raise yours.
- Daniel Goleman's 1995 book Emotional Intelligence catapulted the term into widespread use in the business world.
- One study found that EQ (emotional intelligence) is the top predictor of performance and accounts for 58% of success across all job types.
- EQ has been found to increase annual pay by around $29,000 and be present in 90% of top performers.
Evolution doesn't clean up after itself very well.
- An evolutionary biologist got people swapping ideas about our lingering vestigia.
- Basically, this is the stuff that served some evolutionary purpose at some point, but now is kind of, well, extra.
- Here are the six traits that inaugurated the fun.
The plica semilunaris<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8xOTA5NjgwMS9vcmlnaW4ucG5nIiwiZXhwaXJlc19hdCI6MTYxMTgyMzg1NX0.ZY8qmhtoZfbRMAqrNnmbgyk7GLabglx_9lBq3PKcy7g/img.png?width=980" id="99882" class="rm-shortcode" data-rm-shortcode-id="68e8758894b0359c6ef61b2c158832b2" data-rm-shortcode-name="rebelmouse-image" />
The human eye in alarming detail. Image source: Henry Gray / Wikimedia commons<p>At the inner corner of our eyes, closest to the nasal ridge, is that little pink thing, which is probably what most of us call it, called the caruncula. Next to it is the plica semilunairs, and it's what's left of a third eyelid that used to — ready for this? — blink horizontally. It's supposed to have offered protection for our eyes, and some birds, reptiles, and fish have such a thing.</p>
Palmaris longus<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8xOTA5NjgwNy9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYzMzQ1NjUwMn0.dVor41tO_NeLkGY9Tx46SwqhSVaA8HZQmQAp532xLxA/img.jpg?width=980" id="879be" class="rm-shortcode" data-rm-shortcode-id="970e9c15f3c3d846dde05e2b2c6ebf12" data-rm-shortcode-name="rebelmouse-image" />
Palmaris longus muscle. Image source: Wikimedia commons<p> We don't have much need these days, at least most of us, to navigate from tree branch to tree branch. Still, about 86 percent of us still have the wrist muscle that used to help us do it. To see if you have it, place the back of you hand on a flat surface and touch your thumb to your pinkie. If you have a muscle that becomes visible in your wrist, that's the palmaris longus. If you don't, consider yourself more evolved (just joking).</p>
Darwin's tubercle<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8xOTA5NjgxMi9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY0ODUyNjA1MX0.8RuU-OSRf92wQpaPPJtvFreOVvicEwn39_jnbegiUOk/img.jpg?width=980" id="687a0" class="rm-shortcode" data-rm-shortcode-id="b38a957408940673ccc744f0f6828d18" data-rm-shortcode-name="rebelmouse-image" />
Darwin's tubercle. Image source: Wikimedia commons<p> Yes, maybe the shell of you ear does feel like a dried apricot. Maybe not. But there's a ridge in that swirly structure that's a muscle which allowed us, at one point, to move our ears in the direction of interesting sounds. These days, we just turn our heads, but there it is.</p>
Goosebumps<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8xOTA5NzMxNC9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYyNzEyNTc2Nn0.aVMa5fsKgiabW5vkr7BOvm2pmNKbLJF_50bwvd4aRo4/img.jpg?width=980" id="d8420" class="rm-shortcode" data-rm-shortcode-id="f735418322b34382dcd882299c9ccc48" data-rm-shortcode-name="rebelmouse-image" />
Goosebumps. Photo credit: Tyler Olson via Shutterstock<p>It's not entirely clear what purpose made goosebumps worth retaining evolutionarily, but there are two circumstances in which they appear: fear and cold. For fear, they may have been a way of making body hair stand up so we'd appear larger to predators, much the way a cat's tail puffs up — numerous creatures exaggerate their size when threatened. In the cold, they may have trapped additional heat for warmth.</p>
Tailbone<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8xOTA5NzMxNi9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYxMDMzMDc3N30.p9BEtkf3-PV3EtDSQMUGUeopsimiCHUagx97P4f8IBw/img.jpg?width=980" id="e8ab8" class="rm-shortcode" data-rm-shortcode-id="0063ce99bdd22fbebe1279244b87935c" data-rm-shortcode-name="rebelmouse-image" />
Coccyx. Image source: decade3d-anatomy online via Shutterstock<p>Way back, we had tails that probably helped us balance upright, and was useful moving through trees. We still have the stump of one when we're embryos, from 4–6 weeks, and then the body mostly dissolves it during Weeks 6–8. What's left is the coccyx.</p>
The palmar grasp reflex<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8xOTA5NzMyMC9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYzNjY0MDY5NX0.OSwReKLmNZkbAS12-AvRaxgCM7zyukjQUaG4vmhxTtM/img.jpg?width=980" id="8804c" class="rm-shortcode" data-rm-shortcode-id="45469ca5ee5f43433a782f7d4ac0a440" data-rm-shortcode-name="rebelmouse-image" />
Palmar reflex activated! Photo credit: Raul Luna on Flickr<p> You've probably seen how non-human primate babies grab onto their parents' hands to be carried around. We used to do this, too. So still, if you touch your finger to a baby's palm, or if you touch the sole of their foot, the palmar grasp reflex will cause the hand or foot to try and close around your finger.</p>

Are there innate differences between female and male brains?
People have searched for sex differences in human brains since at least the 19th century, when scientist Samuel George Morton poured seeds and lead shot into human skulls to measure their volumes.
