How to design a lightsail that won't tear or melt on an interstellar voyage

Breakthrough Starshot plans to send microscopic probes to Alpha Centauri using lightsails. Previous conceptions of these structures have imagined them being passively pushed by light from the sun, but Starshot's laser-based approach requires rethinking the sail's shape and composition so it won't melt or tear during acceleration to relativistic speeds.

3D-printed graphene oxide soft robots (w/video)

Researchers report the preparation of a moisture sensitive graphene oxide soft robot by combining direct ink writing and constrained drying. To do so, they realized a uniform 3D macrostructure with graphene oxide nanosheets highly aligned and compacted inside.
