This is most probably one of the latest editions SteemSTEM distilled before the fork, as can be read from many places already now. Anyways, @lemouth is still there to cook up this distilled of the best SteemSTEM posts of last week.

This week we shed light on this post from @loveforlove where the work from Kohler and Goodall on chimps, in the context of learning and the associated complex responses, is discussed. Topics like habituation and conditioning are approached, as well as more involved social behaviours and observational learning.
We are happy to share with you, week after week, another medical procedure depicted in its greatest details thanks to @anaestrada12. This week, she discusses paracentesis that is a common practice in emergency services to diagnose peritonitis and for therapeutic purposes in cases of stress ascites.
