Scientists have now figured out how to cool things to below absolute zero. BELOW absolute zero.
Let me just rephrase that. There’s a temperature in the universe that things can’t go below because heat is energy and at that temperature there’s literally no more energy left to lose. Going below absolute zero is like eating a cake that isn’t there. THERE IS NO CAKE, STOP TRYING TO EAT IT also all your molecules are inert and you can’t chew things okay this metaphor is breaking down.
Then scientists came by and said, “we’re gonna take some more energy out of it anyway because quantum” and I guess the universe said “oh, well, quantum” or something because now this happened.
There was a smart guy who once said that any sufficiently advanced science is indistinguishable from magic and clearly he was right because this shit is fucking sorcery.
Hair ice, also called silk frost, is a type of ice formation that looks like silky hair and seems to only appear on woody, barkless materials on the ground. The ice structures tend to grow out of a small pore in the wood, sort of like hairs on the human head. Hair ice, is ice that grows outward from the surface of the wood, as super-cooled water emerges from the wood, freezes and adds to the hairs from the base.
Introducing my favourite protein: Kinesin! It’s so cute and I really want it as a plushie.
Kinesin is the little orange-y thing that looks like two big feet, walking over a microtubule. The big blue ball it carries is a vesicle full of large molecules that were produced in the center of the cell. Kinesin is a motor protein that carries this vesicle to where the molecules are needed in the cell, e.g. at the membrane. Kinesin’s partner in crime is Dynein that walks the microtubules towards the center of the cell. Especially Kinesin is thought to play an important role in mitosis, meiosis, axonal transport and more.
This gif was made from the brilliant animation made by BioVisions for Harvard University. ‘The Inner Life of the Cell’ is amazing and I think everybody should have seen it at least once in their life to get a better idea how much of a miracle life really is.
