Finally we are seeing some encouraging results from high technology in the use of what might be called "cybernetic medicine". The article explores how researchers are using technology which places human cells in electronic test apparatus in order to use them in lieu of live animals for testing.
This is similar to how cow cells have been grown en vitro to produce something akin to meat (which still doesn't have the texture of say a steak, so there is still a long way to go before lab-grown meat could reasonably replace beef from cattle).
In this case, living cells are not being used for food, but for testing with drugs/chemicals for toxicity. The goal of the primary researcher is to replace animal testing (in this case, on canines) with this technology so that dogs can be free to do what they do best - bite militant fundie muzz and criminals.
