Camp Century, a top-secret US military base, was built under the ice sheets of Greenland in 1960 to house missiles. Built under the cover of climate research, it housed 200 people and was powered by the world’s first portable nuclear reactor. Denmark didn’t uncover the base’s existence until 1995. 00

Math and Nature Inspired This Artist’s Mesmerizing Spiral Sculptures
You don’t need to be a math expert to appreciate John Edmark’s “Blooms.” When photographed with a short shutter speed or under a strobe light, the rotating sculptures take on an otherworldly energy. But knowing the numbers behind Edmark’s designs makes them even more impressive.
Edmark, an artist and professor at Stanford University, uses the Golden Angle when sculpting his spirals. The Golden Angle is derived from the Golden Ratio, which (as Edmark describes it) is when “the smaller is to the larger, as the larger is to the whole.” In a circle, that angle comes out to roughly 137.5°. This number appears all over the place in nature, from the spiraling sequence of leaves in succulents to the arrangement of seeds in sunflowers.
John Edmark recreates this perfect pattern in his studio. To see how his does it, check out the video from SciFri below.

Scientists Decode the Secret of Glowing Mushrooms
We’re just going to come right out and say it: mushrooms are weird. They pop up without warning and they can change the weather. Many of them can also glow in the dark, and we don’t know why. Now, at least, we might know how, as researchers writing in the journal Science Advances reveal the bizarre, “promiscuous” process of fungal bioluminescence.
Lots of animals light themselves up, glowing or flashing to send messages, find prey, or flirt with potential mates. And scientists have a pretty good understanding of how that happens. When a pair of enzymes called luciferin and luciferase combine with energy and oxygen, the resulting chemical reaction makes a compound called excited oxyluciferin. But excitation is not sustainable, so the oxyluciferin releases its fizzy energy in the form of light.
Scientists hypothesized that fungi were probably doing something similar (although really, with fungi, anything is possible).
To learn more, an international team of researchers analyzed extracts from two glowing mushrooms, Brazil’s Neonothopanus gardneri and Vietnam’s poisonous Neonothopanus nambi.
They found that both species were sticking with the traditional luciferin-luciferase playbook … kind of. They were definitely making their own proprietary blend similar to excited oxyluciferin.
But the luciferase that the mushrooms were using was, in the scientists’ words, “promiscuous”—that is, it was happy to mix and mingle with multiple types of luciferin. And while the only bioluminescent fungi we know about all glow green, the researchers write that the luciferase’s indiscriminate approach could lead to a rainbow of lights in different colors and intensities.
“Future work on the isolation, characterization, and heterologous expression of the luciferase will stimulate the development of fungal bioluminescence–inspired applications,” the authors write. In other words, hey, we know about this bizarre thing now. We might as well use it.

Why Do Our Bodies Need Electrolytes?
Sports drinks like Gatorade are marketed as a source of body-boosting electrolytes, which begs the question: What exactly is an electrolyte, and why are they so important? The short answer is that they’re dissolved salts, which break down into positively and negatively charged ions that conduct electricity and water. These charges control nerve impulses and the flow of water in our cells.
Electrolytes are lost from the body through sweat—but seeing as how we get plenty from food, should we really guzzle sugary athletic beverages after a tough workout? The American Chemical Society weighs in with their latest Reactions video:

How a Pelican Survives a 40-Foot Drop Into the Ocean With No Broken Bones
Pelicans dive into the ocean all the time. They hunt by spotting fish from high in the air before zeroing in and dropping down into the water dozens of feet below. While they make it look like no big deal, it’s a dangerous maneuver. From 40 feet up, if they hit the surface of the water wrong, it’s like slamming into a brick wall.
PBS’s video series Deep Look recently took a dive into how brown pelicans manage to pull this off without breaking their necks, going blind, or otherwise maiming themselves. Part good form, part physiology, it’s an impressive feat. The muscles around their back tighten to protect their spine, a membrane flashes over their eyes to protect their vision, and their sword-shaped bill slices through the water.
And once they hit, they’ve got a built-in life vest that keeps them floating along the surface of the water instead of plunging down into deeper waters. When the pelican takes a deep breath as it dives, air rushes into special sacks under their skin and in their bones, called pneumatic foramina, that act like a cushion against the water. Their signature gular pouch doesn’t just hold fish, either. It acts like a parachute to slow the bird down, only inflating with liquid instead of air (it catches up to three gallons of water in the process).
Watch the full video to find out more.
If you’re really into pelicans, you can also experience a GoPro view of a pelican learning to fly.
