Foxes are described as “dog hardware running cat software.” These animals are incredible problem solvers, build extremely detailed mental maps of their environment, and can recognize individuals. Over the last 70 years, some foxes were selectively bred to be friendly to humans, and these descendants behave completely differently than their wild counterparts.

The Cascadia Subduction Zone is a sleeping monster lurking just off the Northwest coast of the United States. It extends 600 miles between Northern California and Vancouver B.C. and experiences a massive megathrust earthquake every 250 years on average. The last one happened 321 years ago and scientists say there is a 30% chance we’ll see another in the next 50 years. It’s expected to rival the 9.0 quake that shook Japan for 6 minutes, which was the most destructive natural disaster in human history. It unleashed a tsunami that reached 100 feet in some areas, caused an estimated $360 billion in damages and claimed some 16,000 lives.

We know animals are intelligent, but what we don’t know is how to compare the intelligence of one animal to another. Our Animal IQ Rubric helps us measure five domains of intelligence to finally answer the question: how smart are Earth’s animals?
For generations, humans have wondered if other creatures think the way we do. Scientists devise tests, experiments, and devices to probe the cognition of our fellow fauna. Researchers use puzzle boxes, hidden cameras, brain scans, and mirror tests to suss out social skills, learning ability, vocalization, memory, and even collaboration.

The Ouray Ice Park is the world’s premier location for ice climbing and attracts visitors from around the world. Nobody has ever attempted to create anything on this scale. How do they do it?
The people who make this place every winter call themselves ice farmers. They rely on a complicated system of above-ground plumbing and intimate knowledge of ice to build this frozen marvel. But even ice farmers get surprised by the behavior of ice and water. The water molecule is one of the strangest on the planet, and there’s so much more for scientists to learn about it.

American prairies were once home to as many as 60 million bison. But when ranching and agriculture displaced elk and bison from the prairies, America’s grasslands all but disappeared. Now, the Nature Conservancy manages the largest remaining protected tract of tallgrass prairie in the entire world, the Joseph H. Williams Tallgrass Prairie Preserve in northeastern Oklahoma.
This 40,000-acre expanse is much more than grass. It is a biologically rich habitat that harbors a diverse collection of plant and animal species—more than 750 species of flora and 80 different mammals. This prairie is also a vital component in nature’s fight against climate change. The key to keeping the prairie healthy? Bison.

Landslides occur in mountainous areas all over the world. One of the most devastating in US history struck on January 9, 2018, when 1,000,000 cubic tons of mud, boulders, and uprooted trees barreled into the sleeping town of Montecito, CA, claiming 23 lives and causing around $1 billion in damage.

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.

Antarctica is home to McMurdo Station, the U.S. Antarctic Program’s base of operations, and a handful of other research stations. These stations are occupied by scientists and other staffers, all of whom generate a whole lot of waste. And every scientist and staffer, like everybody else on Planet Earth, poops. (If you didn’t know this, maybe give “Everyone Poops” a read after you watch this episode.)
Under the Antarctic Treaty System, an international agreement to protect the continent, waste of any kind—garbage, human poop, you name it—can’t be left on the continent. So what happens to it? To find out, Caitlin and Arlo embark on their most peculiar Antarctic quest yet.
At McMurdo Station, as Caitl...

Icefin is testing technologies designed for exploring Jupiter’s icy moon Europa. But before its successors go into space, this robot has a serious job on Earth: taking measurements from under a glacier so researchers like Georgia Tech astrobiologist Britney Schmidt can better understand how climate change is affecting Antarctica’s vulnerable ice. NOVA’s Caitlin Saks and Arlo Perez meet with Britney and her team of young scientists and engineers on the 8-mile-long Erebus Ice Tongue to discover how this robot is gathering data before its “grandkids” leave our planet.
Then, Britney, her team, and Icefin head to the Florida-sized Thwaites Glacier on the West Antarctic Ice Sheet. Thwaites is one of the most remote places on Earth, but this so-called “Doomsday Glacier” is on the front line ...

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. Inside one finds all the trappings of early Antarctic life: seal blubber, science experiments, and of course a desiccated penguin.
Today, living in Antarctica is a bit different. But still, an eclectic band of scientists and support personnel are drawn to the continent and, every year, a crew makes their home on ...

Five stories high and emerging from the Taylor Glacier in the Dry Valleys of Antarctica, Blood Falls seeps into an ice-covered body of water called Lake Bonney. It’s one of the continent’s most enigmatic natural features and has fascinated scientists for decades. What makes it red? Does it always flow? And can anything actually survive near it? To find out—and see just how bizarre Blood Falls is with their own eyes—Caitlin and Arlo travel to the Dry Valleys, about 60 miles from McMurdo Station. There, they meet with microbiologist Jill Mikucki and hydrogeologist Peter Doran to investigate why this glacier looks the way it does, what lives there (spoiler: CHARISMATIC MICROBES!), and what clues it holds for finding and understanding life on other planets and moons in our solar system, like Mars, Ju...

Inhabiting the Ross Sea—as far south as McMurdo Sound—Weddell seals (Leptonychotes weddellii) have the most southerly distribution of any mammal on Earth. Scientists began studying a breeding population of Weddell seals in 1968 and quickly found out these pinnipeds don’t always have it easy. Giving birth and raising young is particularly challenging in Antarctica’s extreme conditions, forcing Weddell moms and pups to bear sub-zero temperatures and prevailing winds. How do they manage to do it so gracefully? (OK: they’re admittedly way more graceful in the water than on land.) To find out, NOVA hosts Caitlin and Arlo travel to...
