The three human figures and two animals that make up the Blythe Geoglyphs - or Blythe Giant Intaglios - are enormous. So big in fact, that they can’t be fully appreciated from the ground. But the figures were carved into the earth long before air travel was invented. So who made them...and why?

Jinkyu “JK” Yang sees endless possibilities in a single sheet of paper. The aeronautics and astronautics professor at the University of Washington uses origami as a creative way to design foldable structures. The resulting shapes could inform new designs for a rocket’s landing gear, medical devices, or solar panels — all while pushing the boundaries of where art and science meet.

Hurricanes are the most powerful and destructive storms on the planet. And 2020 surpassed all expectations, becoming the most active hurricane season on record. Have you ever wondered how they form? Or how climate change is affecting them? And, what can we learn from a lab that creates hurricane-force wind and rain to test the strength of houses?
Weathered is a show hosted by meteorologist Maiya May and produced by Balance Media that helps explain the most common natural disasters, what causes them, how they’re changing, and how we can prepare.

Vikram Baliga studies anatomy and movement of animals in the Department of Zoology at the University of British Columbia. He examines how birds use their wings to generate force and carry them through the sky. Truly understanding the mechanics requires hands-on study — so Baliga sources bird cadavers from museum collections at the Beaty Biodiversity Museum. It sounds morbid, but with a closer look, humans can learn how to build better aircraft or automobiles, using superior natural design informed by millions of years of bird evolution.

Wild horses made their home on the islands of North Carolina centuries ago, supposedly descendants of horses brought by shipwrecked colonizers. Today, they are celebrities on these islands, creating a tourist frenzy and drawing thousands of people every summer to the northern beaches of North Carolina.
But the situation is complicated. The horse population needs to be managed because they can cause serious damage to the ecosystem. How can we respect these horses and keep them wild while protecting the islands?

Though the creatures can't “say” how they feel, exactly, Bonnie uses data to translate their behavior into something we can understand and respond to. Are the giraffes happy? Do penguins get too hot? Can the sheep get a good night’s sleep? As the zoo’s animal welfare scientist, Baird answers these questions and more to help keep the animals healthy and content.

The octopi’s sophisticated nervous systems and sensitive suckers allow it to do incredible things like escape aquariums — but Sivitilli is learning how each of an octopus' eight arms might actually have a mind of its own.

There are a LOT of trees in the Blue Ridge Mountains, and they’re responsible for that dreamy blue haze on the horizon.
Trees produce fine mists of volatile organic compounds (VOCs), which scatter blue light waves. But these compounds are also a key ingredient in ground-level ozone, and in the mid-90s the area had serious air quality issues. Not only was it dangerous to breathe, but the hazy blue was also disappearing from the horizon.
But it wasn’t just the tree's fault. Here’s what happened...

Finding — and filming — penguins was hosts Caitlin Saks and Arlo Pérez’s top priority during their month-long stay at McMurdo Station. With four species of penguin living in Antarctica, including the Adélie, the most widely-distributed penguin species in the world, tracking down these waddling wonders might sound simple.
To find Adélies, Caitlin and Arlo set out on a quest to Cape Royds, home to the southernmost Adélie penguin colony in the world. There, they meet with expert Jean Pennycook to learn about why people love these black and white birds and how Antarctica’s penguin populations are indicators of climate change. But non-ideal conditions and gusting winds put a damper on their plans (and the penguins they do come across seem to be either busy pooping or getting busy with each other). Caitlin and ...

Antarctica is an otherworldly land of extremes. But perhaps nothing there is as extreme as Mount Erebus, one of Antarctica’s two active volcanoes and the southernmost active volcano on Earth. Conveniently, Erebus’ summit is a mere 25 miles from McMurdo Station, Antarctica’s largest research base.

At altitude in -30° F conditions, they embark on foot and see firsthand how breathtaking (literally) Erebus is — and why an active volcano in a land of ice is a scientific wonder.

Generally, an adult human consumes around 1,600 to 3,000 calories daily. But in colder climates, people need to eat more: Keeping our warm-blooded bodies warm requires a lot of energy. It’s so cold in Antarctica that the average person needs to consume 3,200 to 5,000 calories a day (watch out, Michael Phelps). And because the continent is frozen, no food grows there naturally.
So how do the hundreds of scientists and support personnel who visit Antarctica’s McMurdo Station each year stay fed?

To discover Antarctica’s dazzling hidden underbelly, host Arlo Pérez meets with Steve and his fellow Antarctic diver Rob Robbins, while host Caitlin Saks explores the McMurdo Aquarium with evolutionary physiologist Chi-Hing Christina Cheng. Arlo and Caitlin learn that the Antarctic marine realm is not only spectacular to see, but fascinating for scientists to study. The water is so cold that fish inhabiting it should freeze like an icicle, a phenomenon that evolutionary biologist Paul Cziko uses supercooled water, snow, and fish guts to demonstrate.

People have been visiting Antarctica for over a century—and hosts Caitlin Saks and Arlo Pérez can actually see what living there used to be like, because some of the early explorers left all their stuff! Ernest Shackleton’s ill-fated ship Endurance was only recently rediscovered, but the 1910-1913 expedition led by Robert Falcon Scott (more commonly known as the Terra Nova Expedition) left its “home-base” hut still intact, and it’s now a museum.
