New research could improve the safety of drone shows, warehouse robots, and self-driving cars. By Jennifer Chu, MITDrone shows are an increasingly popular form of large-scale light display. These shows incorporate hundreds to thousands of airborne bots, each programmed to fly in paths that together form intricate shapes and patterns across the sky. When they go as planned, drone shows can be spectacular.

By Rhiannon Koch, University of AdelaideScientists in Australia and their international team members have mapped the forces acting inside a proton, showing in unprecedented detail how quarks, the tiny particles within, respond when hit by high-energy photons. The research team includes experts from the University of Adelaide who are exploring the structure of sub-atomic matter to try and provide further insight into the forces that underpin the natural world.

Engineers at MIT have demonstrated the first fully 3D-printed, droplet-emitting electrospray engine. The device, which would be ideal for enabling small satellites to make in-orbit maneuvers, can be produced for a fraction of the cost of traditional thrusters.
