World's smallest computer makes a grain of rice look like a giant jellyfish.

Could be big news for implanted computers.

You thought your Raspberry Pi was dinky? Try taking a look at the latest miniscule computer created by the University of Michigan – if you can even see it, that is.

Wrestling the crown of smallest ever computer from engineers at IBM, the University of Michigan has created a temperature sensing computer measuring just 0.04 cubic millimeters. That makes it a tenth the size of the IBM's previous smallest-ever computer.

To put the size into to context, that's not a giant jellyfish in the image up top – that's actually the computer sat next to a single grain of rice.
