Australia’s salt lakes present in a kaleidoscope of colors. Some are luminescent yellow, some are persimmon-orange, and some—the ones with the most extreme conditions—are neon pink. That pink color is the product of a pair of extremophiles: Dunaliella salina, a type of microalga, and Salinibacter ruber, a halophilic bacterium. When exposed to sunlight, these organisms produce beta-carotene—the same pigment that gives carrots, crayfish, and flamingos their distinctive color. Over the last 20 years, two of Western Australia's most iconic pink lakes have lost their distinctive color due to climate change and resource over-extraction. Yet experts believe the lakes can bloom pink once again. Find out what scientists recommend at the link in bio. Photographs by Daniela Tommasi (@daniela_tommasi_photography)

New fossilized footprints may offer the first real evidence that different dinosaur species traveled together. Discovered in Canada's Dinosaur Provincial Park, the 76-million-year-old footprints suggest a small group of horned dinosaurs may have been joined by an armored ankylosaur and a small two-legged theropod. And like many of your favorite adventure stories, this band of travelers may have been stalked by fearsome foes: a pair of large carnivorous tyrannosaurs. Not all scientists agree on the interpretation, but the finding could reshape what we know about prehistoric social dynamics.

A tornado made of boiling plasma that can rotate at speeds up to 186,000 miles (299,338 km) an hour might seem like an extraordinary phenomenon, but there are thousands of them on the sun at any given moment.

The great outdoors offers so much excitement and adventure, but it’s important to slow down and appreciate the quieter moments as well. That’s what Nat Geo photographer @jodymacdonaldphoto was reminded of on her trip to Oregon. “We’re wired to keep moving. But nature rewards patience. When I take the time to stop, stay quiet, and simply observe, I notice how much I’ve been overlooking. Some of my favorite photos have come from simply being still long enough to see them. The more I pay attention, the more I realize what I’ve been missing.” | @ToyotaUSA #4Runner is your window to the wild #ToyotaPartner

For centuries, humans have lived underground. Today, that ancient practice is under dire threat—even as cave life makes more sense than ever in a warming world. National Geographic Explorer Tamera Merino has traveled the world searching for some of Earth’s last remaining cave societies to document. From Turkey to Australia, Spain, Tunisia and beyond, she found shelter from heat and hardship, as well as enduring traditions shaped by resilience and ingenuity. As modernization spreads, these ancient cave societies are quietly disappearing—along with the lessons they hold about sustainable living and what it means to adapt without erasing the past.
