In the future, signs will be instantly rewritable and walls will change color at the flip of a switch. A research team at the University of California at Riverside has created a new magnetically activated, instantly and reversibly color-changing material with potentially groundbreaking applications. The technology is based on that used by colorful birds, beetles, and butterflies: instead of static pigments, the material employs "structural color," which depends on the interference effects of light.

At press time, no new launch date had been set, but if you’re following Swift closely or have an insatiable love for exotic astrophysical phenomena, you might enjoy a little tune written and performed by an a cappella group known as the Chromatics. Here’s an excerpt from the aptly titled “Swift Song,” concerning the function of the observatory:
Swift is the satellite that swings/ Onto those brightly bursting things/ To grab the multi-wavelength answer to what makes them glow.
