2) Scientists have to wear a lot of PPE when they do their lab work to prevent contamination.
3) I didn't know ultraviolet light could be used to sterilise laboratories.

It was interesting to learn that anything that touches a bone, even when it is in the ground can contaminate it. I also learned that it is impossible to tell human contamination from ancient DNA. ]]> 2021-12-08 07:54:52 UTC https://padlet.com/jwrigh56/enm2hkt3h1y0iglf/wish/1935329431
