As the Midwest sizzles through another heatwave, something unexpected is turning up the steam—millions of acres of cornfields. Known as "corn sweat," this quirky weather effect happens when corn plants release huge amounts of moisture into the air, enough to crank humidity up by 30 to 40 percent. This added moisture can make heatwaves more challenging—and dangerous—by reducing the body's ability to cool itself.

In the ruins of a Byzantine monastery, archaeologists uncovered a tomb containing the remains of a skeleton wrapped in a metal chain. Long thought to be a male religious hermit, new analysis reveals the remains belonged to a woman, reshaping assumptions about who practiced extreme forms of early Christian asceticism—practices undertaken with the firm belief that emulating the suffering of Christ would bring one closer to God.

Tadpoles develop inside a gelatinous mass that Filippo Carugati (@wildlais), a primate biologist, captured during fieldwork in Madagascar’s Maromizaha rainforest. “I went out nearly every night, checking plants above the temporary pools that form during cyclone season, looking for egg clutches,” says Carugati. “There were frogs everywhere, their croaks filling the night.”

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. Over the last few years, astrophotographer Miguel Claro has captured remarkably detailed footage of these solar twisters swirling above the sun's active surface.

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)
Limiting your sugar intake can have a pretty sweet and surprising impact on your life, according to new research. Reducing sugar, even just for a few days, comes with a number of benefits—better skin, improved stress levels, and more. But not all sugars are made equal.

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
