Sometimes you watch Bones, a TV show, and google every new thing the characters get excited about. These are called Lore-Drops. Because 9 out 10 times, it's an actual real-life exciting discovery!!

Rainbow Eucalyptus Trees
Eucalyptus deglupta is a species of tall tree, commonly known as the rainbow eucalyptus, Mindanao gum, or rainbow gum that is native to the Philippines, Indonesia, and Papua New Guinea. It is the only Eucalyptus species that usually lives in rainforest, with a natural range that extends into the Northern Hemisphere. It is characterized by multi-colored bark which starts with bright green patches that will gradually transform into orange, maroon, and blue hues.

Shortest math paper ever.
And with so much impact! It just disproved a widely accepted theorem from the year 1769 in 5 rows!!!
I'll never publish anything even remotely badass like this! But I want it so much!!!

This is like imagination training session and it is so cool! To imagine how many prehistoric species we'll never even learn about existing because i.e. they were too soft to leave a fossil. To imagine how bizarre and monstrous we would see animals of today if we only judged by their skeletons as we do with dinosaurs. And to imagine triceratops' mating dance😉

I still think the most insane coincidence that's ever happened to me was one time I was in a group of three people in a science lab doing basic color stuff where you look through a special thing and mark off where the color spectrum ends. We were supposed to be able to see from 400 to 700 nm or smthn like that, but me and one of the other guys could see 390-710, so we figured the machine was broke a lil bit. Other guy could see exactly what he was supposed to.
We spent about 20 minutes arguing about it before we finally called the teacher over and he looked, laughed, and said "yeah color vision is a spectrum, I usually get about one student a year who can see a little bit into ultraviolet and infrared. Been teaching this class for 30 years and I've never had two students in the same class do that tho" and then just walked away like he hadn't subtly shifted our whole understanding of human biology.
I feel so bad for the one normal guy tho, for about 20 minutes he was getting absolutely gaslighted to hell about something he could clearly see. I think he thought he was going insane.

Crash Course Anatomy & Physiology Notes, Tissues, Part 1
every cell in the body has its own specific job related to maintaining homeostasis
cells are the most basic building blocks in the hierarchy of complex structures
tissues are the fabric of the body
when 2 or more tissues combine, they form organs
type of tissue defines its function
there are 4 primary tissues
nervous tissue provides control and communication
muscle tissue gives movement
epithelial tissue lines the body cavities and organs and cover and protect the body
connective tissue provides support
histology - the study of tissues
carmine - a red dye derived from the scales of crushed-up cochineal insects, used to highlight different cell structures
nervous tissue forms the nervous system which regulates and controls the body's functions
nervous tissue senses stimuli and sends electrical impulses through the body in response to those stimuli
nervous tissue is made up of two types of neurons and glial cells
neurons sense stimuli and send messages to your brain
neurons are made up of the cell body (soma), dendrites, and the axon
cell body (soma) is the cell's life support, it has all the necessary parts like a nucleus, mitochondria, and DNA
dendrites are bushy and look like the trees that they're named after, they collect signals from other cells to send back to the soma
axon is long and rope-like, it's the transmission cable and it carries messages to other neurons and muscles and glands
glial cells provide support, insulation, protection and tether to blood vessels
muscle tissues can contract and move
the three types of muscle tissue are skeletal, cardiac, and smooth
skeletal muscle tissue attaches to all the bones in your skeleton, it pulls on the bones or skin when they contact to make your body move
skeletal tissue is made up of multinucleate and striations
cardiac muscle tissue cells are generally uninucleate meaning one nucleus, have striations
smooth muscle tissue lines the walls of the blood vessels and hollow organs, don't have striations

Plasma cleaning of Petri dishes
We pump out the air from the chamber and let in only a low amount of highly ionized gas. The ionized gas has this beautiful color you see. The Petri dishes will be now sterile, perfectly clean, and adhesive for my samples for measurements.

Scorpions are fluorescent! That means that they take uv light (which we can't see) and their skin re-emits it at a wavelength we can see!! That's so darn cool! Scorpions look like they glow but they don't their skin is just really neat!!!
