Researchers demonstrated the first fully 3D-printed, droplet-emitting electrospray engine. The low-cost device can be fabricated more quickly than traditional thrusters, potentially from on board a ...

Drawing inspiration from ancient art forms – kirigami (paper cutting) and origami (paper folding) – researchers have found a new way to create metamaterials. Artificially engineered ...

Instead of space-time’s three spatial dimensions and one of time, the physics of our world could be encoded into a set of odd geometrical shapes – and studying them may chart a new ...
