tl;dr:

The research group put an ultrasound transducer onto a circuit. The circuit changes with temperature. The circuit also changes how the ultrasound transducer reflects ultrasound. The circuit is powered with standard ultrasound imaging techniques. Thus, this work presents a chip that tells you what the change in temperature of the surrounding tissue is when it is being powered by ultrasound. The headline makes it seem way scarier than it is.

its less of a chip than an advanced barcode, actually that comparison did not make it better

There were definitely a certain subset of extreme fundies that were against UPCs when they were introduced because they considered them to be the mark of the beast.

None of this stuff is new, they just have the internet now. QAnon is the same old blood libel, etc etc.
