Scientists using high-powered microscopes have made a stunning observation of the architecture within a cell – and identified for the first time how the architecture changes during the formation of gametes, also known as sex cells, in order to successfully complete the process.

Cellular automata are probably the closest things to machine life that most people have gotten an opportunity to experiment with in recent years. John Conway invented a piece of software titled the Game of Life in 1970. He carefully set up the rules to create a balanced world. While this might sound like old news, it has allowed scientists to actually simulate certain real world systems.

Living Architecture: How Synthetic Biology Can Remake Our Cities (TED) by Rachel Armstrong. iPad, Kindle, Barnes & Noble. Rooted in cutting edge biology and materials science, as well as contemporary art, Armstrong's account of how we'd build biological cities feels at first like a thought experiment but evolves into a plausible vision of tomorrow's cities.
