Question #1: CRISPR ()[edit]

Sorry if you've already talked about this in your latest show (I just saw that a new one came out and I didn't have time to listen to it yet). Last week in science or fiction there was an item about >1500 off-target mutations in CRISPR-Cas9 treated mice. Science Friday podcast also covered this (http://www.sciencefriday.com/episodes/june-9-2017/ at t-26:55). tl;dl: It seems this finding is controversial: the statistics are shaky, and so is the editing technique used. On top of that, the article is a Letter-to-the-Editor, which does not go through peer-review. So maybe not all is lost with CRISPR-Cas9, and even if there are more off-target mutations than previously thought, CRISPR remains a revolutionary gene-editing tool as compared to other techniques like zinc-finger nucleases. I'm sure Bob is relieved to hear this. Cheers, Marc Züst

Science or Fiction ()[edit]

Item #1: Vienna has a population of 1.8 million, which is the same as its population in 1900, and represents over one quarter of the entire population of Austria. Item #2: Both the snow globe and the Pez dispenser were invented and first sold in Vienna. Item #3: Schönbrunn palace, the summer home of the Hapsburgs, was modest by European standards, containing 74 rooms. Item #4: In the old markets of Vienna it was common to find monkey grooming services, to pay to have a monkey remove lice and fleas from your head.
