Researchers in Japan have shown that a slime mold can design a network that is as efficient as one developed by humans over many years: the Tokyo rail system. Furthermore, the slime mold can build its network in a day. A slime mold is what scientists refer to as a single-celled amoeboid organism. When foraging for food, it spreads out as an amorphous mass and then builds tubular connections between the food sources.

The way fungus-like slime moulds grow could help engineers design wireless communication networks. Scientists drew this conclusion after observing a slime mould as it grew into a network that was almost identical to the Tokyo rail system.

Larry and Sergey founded Google because they wanted to help solve really big problems using technology. And one of the big problems we’re working on today is car safety and efficiency. Our goal is to help prevent traffic accidents, free up people’s time and reduce carbon emissions by fundamentally changing car use. So we have developed technology for cars that can drive themselves. Our automated cars, manned by trained operators, just...

Over a 1000-km run, superconducting cables can carry far more power than cables of a comparable size. Even taking into account the energy required to cool them, they lose just a third as much energy in transmission. Just as in the case of optical fibres, the technology has been quietly refined over the years and in some senses is ready to be deployed. This will be costly at first, but with tangible benefits that the wider market may just...
