Protip: This is a really bad question to ask when visiting the National Mall. We have 8 buildings surrounding the Mall, and a total of 19 museums, 9 research centers and the National Zoo. A S.H.I.E.L.D agent should know better! 

(We think she means the Smithsonian’s National Museum of Natural History in this case.)  

I love that this is on the Smithsonian’s tumblr

Whoever does social media for the Smithsonian is awesome.

A different take on the typical plant cell diagram. I decided to emphasize the vast quatities of organelles inside just one cell, as opposed to most diagrams that show and label 1-2 of each organelle.

Map of the World by Natural Skin Color

i’m really dumbfounded that i never realized skin colour is literally just caused by being closer to or farther from the equator and the resulting sun exposure and skin darkening

actually, its an adaptation. natural selection. people with darker skin are selected for in areas near the equator, where the melanin that causes the darker color protects them from radiation and protects them from skin cancer and other health defects, and because they are healthier they can pass on that trait more. people near the poles have lighter skin because it allows them absorb more of the limited sunlight to convert to vitamin d. 

THIS IS THE THING SOME PEOPLE HATE OTHER PEOPLE OVER.Evolution of melanin levels based on geographical location.
