Perhaps I should have. Perhaps I would have learned a few things about how people can treated like boxes in a warehouse. All these years later, that man’s tattoo spells out the theory and practice of dehumanisation for me better than any textbook.

They have successfully attached several biofunctionalized polysilicon barcodes to the outer surface of the egg. The labels are injected into a space between the cell wall and the zona pellucida, a membrane that surrounds an egg. During normal reproduction, a fertilised embryo will shed this outer layer along with the barcodes.
Here is their enthusiastic description of the process:
