The U.S. Navy was on a secret mission to find two sunken nuclear subs.

Airing dirty laundry: Being more eco-friendly can start with how you do laundry—from the detergent you use to how you dry your clothes. A quick tip? “One household can cut 800 pounds of carbon pollution every year by washing four out of five loads of their laundry in cold water,” Nat Geo reports.
Role models: Nat Geo Explorer Tara Roberts (pictured above) has helped document the wreckage of slave ships—and reclaimed the stories and artifacts of African captives transported on them. Roberts and fellow Explorer and marine scientist Aliyah Griffith have been inspirations to aspiring divers everywhere, such as Halle Bailey, the star of The Little Mermaid. “It would be so cool,” Bailey told Nat Geo, “to work in marine life.”
Celebrating—and protecting—the seas: How can we safeguard the world’s most diverse ocean ecosystem? Nat Geo has launched a five-year expedition to explore remote reaches of the ocean—and to protect marine life and support local conservation efforts. The Global Expedition is part of Nat Geo’s broader Pristine Seas effort. (Above, a gray reef shark swims over corals in a sea of small reef fish.)
