I thought any of these experiments are carried out on two sets of cells. One normal and the other cancerous. Both exposed to the same test environment and treatment -- shear in this case. And when they claim "70% of cancerous cells died" they mean 70% more of the cancerous cells died than that of the normal cells, where "more" is defined in some acceptable standard.

Yes, but it is not what they say or show. And as long as they don't publish anything more you should be far more sceptical than those journalists were.
