By Elizabeth Landau, Senior Communications Specialist, NASASince the big bang, the early universe had hydrogen, helium, and a scant amount of lithium. Later, some heavier elements, including iron, were forged in stars. But one of the biggest mysteries in astrophysics is: How did the first elements heavier than iron, such as gold, get created and distributed throughout the universe?

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.
