Limit of vision

the long version

"A team of scientists working in the high-security genetic laboratories of Equatorial Systems has made a radical breakthrough, the world's first artificial life form. Containing bioengineered neurons, the new organisms, nicknamed LoVs because they live at the limits of human vision, were originally designed to repair damaged brain tissue. But they soon demonstrated unforeseen attributes; the ability to form colonies, develop specialized functions, and even communicate with humans."--Jacket.
