Naturae makes mosaics. Scientist (developmental biologists) make mosaics (also)... Because cells (tiles) need to "talk" between them to "construct" (build) an organ with a "pattern". And we need to hear (listen) their conversation (talk). I made also Chimeras.

I Wonder:
-If the "positive affective contagion" works also between Drosophila, or even between flies and the researcher himself.
-I wonder also if we are aware that China Research become omnipresent in all fields.
-And our empathy towards them, as a consequence

It’s a lot easier to destroy something than it is to build it back up. It’s true of everything being dismantled in the U.S. right now. (f.i. : The Department of Education, and the East Wing). it will likely take generations to rebuild the things being broken right now.
