Hi-Sci-Fi

According to the US-based Argonne National Laboratories, these self-assembled magnetic “snakes” very much emulate biological life, and do follow Markovnikov’s rule:

“Nickel particles float peacefully in a liquid medium until a giant snake seems to swim by and snatch several particles up, adding to its own mass. The self-assembled “snakes” act like biological systems, but they are not alive and are driven by a magnetic field. The research may someday offer some insight into the organization of life itself.”
