The images in this article are awful: generic shots and captions of a machine shop; a (possibly empty) black box that's supposed to be a testing machine. Where are the actual machines doing the tests? Where's the science?
The main topic of the article is about how Theranos won't share any info about the science or about the machines. So that's probably all the NYT has to work with.
The photo of a couple adjacent "machinist" stations was puzzling. They were pegboards with some carpenter tools like a cordless drill, hammers, wrenches, etc. Not very confidence inspiring.
