WHAT KIND OF WIZARD FISH IS THIS

DUDE THATS A BABY KAIJU

pew, pew!

SCIENCE SIDE OF TUMBLR URGENT

YOU CALLED!?
This fish is not actually spitting bioluminescent spit…it’s spitting out its bioluminescent food! Some clever scientist has put some bioluminescent ostracods in a tank with some little fish. When agitated, these ostracods (tiny shirmpthings) secrete chemicals that, when combined, emit light.
Why?
You’re seeing why right here. Just before the fish spits it out, those light chemicals are filling up the belly of the fish. Now, it isn’t poisonous or anything…but the fish wants NOTHING TO DO WITH IT because the fish has predators too. 
So yeah, if you’re a little fish and suddenly you’re FREAKING GLOWING, your lifespan has just gotten a lot shorter. 
As soon as the fish realizes that there’s light emanating from its belly, it pukes out the glowing juices (and the little shrimp). You can actually see the ostracod in this gif swimming away down toward the bottom of the tank happy as a clam…or a shrimp. 
Evolution is AWESOME.

Robert Sapolsky about his study of the Keekorok baboon troop from National Geographic’s Stress: Portrait of a Killer.

Thiiiiiiis, people, thiiiis!

1. Kill alpha male types
2. Achieve world peace

Got it.

I’ve actually read a lot of Sapolsky’s work.  He’s one of my favorite scientists in the neuro/socio world.

I just watched the documentary and there is so much more about the troop that isn’t in this photoset—not only does the troop have a culture of little aggression and greater cooperation, but any incoming jerk baboons learned within a few months that their shitty behaviour was in no way acceptable, that the troop only rewarded sociability, and they changed accordingly. 

If effin’ baboons can learn this there’s pretty much no reason to believe that our only option in dealing with assholes is to just ignore their behaviour and let it continue.

there really is no excuse.

"incoming jerk baboons" hahaha

OH before I  go to bed I should convey to you all the weirdest fact I learned today

I learned that when a caterpillar is metamorphosing into a butterfly within the cocoon, it is not, as I previously assumed, slowly growing wings and little antennae and whatever else. If we open a cocoon, apparently what we find is that the caterpillar has actually dissolved into a shapeless goo, from which the butterfly will be formed.

goo.

From which the butterfly is formed.

You can, of course, go the philosophical route with this: are they, then, the same creature, pre- and post- this complete reconstitution of the self? If the very brain, the nervous system, has been completely reassembled, how do we identify this as in any way the same?

So here’s the kicker.

Apparently one scientist figured he’d test this out by training a bunch of caterpillars to react negatively to a specific scent, which they would normally not react negatively to. This was all done prior to the cocoon stage.

And these butterflies. These post-goo, completely remade selves? They reacted negatively to the scent, too.

OKAY GOODNIGHT

Stunning photos of tears under a microscope vary by emotion

Follow policymic

"The project, called "The Topography of Tears," captures unique moments in human experience, but there’s also a scientific reason why every tear looks so different. There are three different types of tears: basal (lubricating), reflex (responding to stimuli) and psychic (triggered by emotion). Each type of tear contains different organic substances, and the molecular makeup depends on the causative agent. For instance, emotional tears contain the neurotransmitter leucine enkephalin, a natural painkiller that the body releases to mitigate stress."

Frozen Peas from SuckUK; a fantastic piece of design as metaphor (as well as a super convenient way to make a spherical ice “cube”.

If you truly love me you will buy this for me.

ALRIGHT TUMBLR PEOPLE LISTEN UP FOR FUN SCIENCE TIME!

Sphere basically take less energy to form because of SURFACE ENERGY. Sphere have a lower surface area to volume ratio. Because of this, ice sphere melt slower than your usual cubes. This is the reason at fancy fancy bars with those $30+ glass of bourbon or scotch may serve your drink using these instead of normal ice.

thank you nerd

IT’S LIKE EDAMAME ICE AAAAAAHHH
