If I was a protein I’d like to be non-homologous end-joining protein (NHEJ) so that I could have a pretty easy job and watch everyone else suffer through the chaos of my effects.

200X total magnification of Elodea in isotonic solution.
The dots are chloroplasts, the plant cell organelle devoted to the production of GTP and other forms of energy used by the cell.
Isotonicity refers to the relative concentration of solutes inside and outside the cell. Here, the solution is a low concentration of sucrose in ethanol. The concentration gradient (the amount of solutes distributed between the inside and outside of the cell) is at equilibrium in an isotonic environment.

Going to put this out there…

For those of you believing in the “fractal nature of the universe”…

Just because clusters of neurons slightly resemble certain galaxies,

or because microscopic images of the human iris look a little like spider webs,

or because we look at things with similar patterns and call them “fractals,”

doesn’t actually make them fractals,

or evidence of any kind of spiritual “connection with the Earth,”

or anything beyond coincidences.

I’m serious.

Take a real evolutionary science course and

STOP WITH YOUR HIPPIE BULLSHIT.

Thank you.

Sincerely,

Science

I was looking up the alkene formation of hexene from cyclohexanol and found this mechanism.

FUCK THE CHLORINE LET’S GO GUYS.

i love how tumblr likes to act like it is a bunch of really intellectual activists who understand politics, religion, sexuality, and literature better than most of the human population

when it is mostly hormonal teenagers and incredibly pretentious uninformed college students

Lungs breathing, creepy but cool


:O


I literally just spent five minutes staring in both horror and wonder at this holy everloving fuck
terrifying and gorgeous and REFERENCE MATERIAL




Actually my friends, this is entirely false. Lungs do not expand on their own because the lungs are NOT MUSCLES. Instead the lungs inflate upon voluntary raising of the diaphragm by use of the abdominal muscles. Air flows into the lungs to satisfy the new difference in air pressure. In this gif, the front of the ribcage is oddly fixed to the spinal cord and would break on impact instead of flexibly contorting to the center of force in a blow. Also the lungs would not inflate in this model, which concludes that this mechanical contraption was designed by some special effects student with insufficient knowledge of physiology.
