Not really current despite the 2019 byline:

> This article was originally published in our “Dark Matter” issue in August, 2015.

See the home page of laboratory[1] and their list of publications[2].

One particular publication[3] appears to give substance to the posted article. However to a cursory read, it does not address what would seem to me to be a blatantly obvious problem with the "toaster oven" experimental setup: contamination! If you are looking for the formation of RNA, how in the world can you be sure that the RNA you find didn't wander in on a dust mote? The present world is saturated with biochemicals, and I don't see how any open substrate can avoid be contaminated by them.

Thanks, we've added 2015 above. I wish Nautilus would stop doing that.

Nearly all molecular biology labs have toasters and Waring blenders. It's Waring because an experiment in the 40s or 50s used one really!
