The Web extra at https://youtu.be/aQV_BkOL4vA is a video showing how students from North Carolina State University designed a collar to keep elephants away from farms and villages. In this field test in South Africa, a buzzing sound from the collar causes an elephant to turn away from the protected area. Video by Emma Besaw.
