HHMI scientists have designed a revolutionary “3D printer” for small molecules that could open the power of customized chemistry to many.

Origami inspired vacuum-based muscles that are cheap to make (out of a compressible skeleton of metal or plastic and air or fluid encased in a flexible skin) and capable of lifting 1000x their own weight.

Developing the technology for a “bioprinting” industry where printers lay down layers of living cells.

Technology innovation firm Cambridge Consultants has successfully completed initial trials of the world’s first fully digital radio transmitter – a turning point in wireless design and a real enabler for the ‘Internet of Things’ (IoT) and 5G technology. It’s a radio built purely from computing power.
