Scientists are trying something new—a massive effort to ward off extinction by releasing hundreds of sharks reared in tanks back into the sea.
In Indonesia, a 15-week-old zebra shark named Charlie is pioneering an attempt by aquariums to save fast-disappearing sharks. Experts say this effort might even work—and end up saving many other shark species, too. So which species are next?

Meet Kathlyn: At top, scientist Nesha Ichida releases a young female named Kathlyn into Indonesian waters just 20 minutes after Kathlyn’s sibling, Charlie, swam into the wild. Above, a female juvenile shark named Aubrey cruises a sea pen in Indonesia. The images were taken by Jennifer Hayes and Nat Geo Explorer David Doubilet. Read more.
Attitude, outlook, and longevity: Eating well and staying active have proven health benefits—and so does positive thinking, according to science. Like members of the Sun City Poms pictured above, those with positive mindsets about aging have better self-efficacy and self-mastery, and regulate their impulses in order to live a longer life, Fran Smithreports for Nat Geo.
Panda repopulation: Giant pandas used to roam freely in China, Myanmar, and Vietnam; they’re now found in maybe 1 percent of their historic range, Nat Geo reports — but they’re on the mend.
“Some local people say giant pandas have magic powers,” says Zhang Hemin aka Papa Panda (pictured), who directs many of China’s panda conservation efforts. “To me, they simply represent beauty and peace.”
Learn more about how China breeds these gentle giants—and the problems the bears face when they’re released into the wild.
