The Chernobyl exclusion zone has become a unique wildlife refuge

The highly contaminated Chernobyl region suffers from reduced biodiversity

Although isolation and radiation have driven adaptations in some organisms, decades of radiation have caused ongoing harm to wildlife and vegetation, including population declines in birds and insects. Higher rates of deformities and tumors have also been seen compared with animals in surrounding regions.

The Chernobyl exclusion zone remains a region restricted to public access

It now spans beyond the initial 30-kilometer radius around the nuclear plant to include surrounding areas found to have significant radioactive contamination. Aside from a handful of elderly self-settlers, permanent residency is banned, and access remains tightly controlled due to lingering radioactive contamination.

The genetic diversity of dogs is greater within Chernobyl than in surrounding areas

A 2023 study identified that packs of dogs located just 16 kilometers (10 miles) apart within the exclusion zone were more genetically different from one another than from stray dogs hundreds of kilometers away. Rather than radiation, this is likely the result of inbreeding within isolated packs.

Dubbed 'stalkers,' some Ukrainian youth illegally explore Chernobyl's exclusion zone

A subculture of thrill-seekers, driven by a desire for rebellion and adventure, is representative of dark tourism in the region. Some stalkers sneak past militia posts to venture into abandoned ruins, risking radiation exposure while scavenging for ruins of the past.

About 1,200 'grandmothers' returned to their homes after the Chernobyl disaster

After the evacuation of the Exclusion Zone, about 1,200 mostly elderly women illegally went back to their ancestral villages and became known as the "babushkas of Chernobyl." Some have described the trauma of permanent relocation as less tolerable than potential radiation risks.

Explore illustrative depictions of Chernobyl in comic books

Pieces related to the location since the nuclear disaster have told stories about radioactive vampires and monsters, accounts of bureaucratic corruption and creed, and visual retellings of experiences those in the region lived through before and after the event.

Misleading measurements and fear-based reporting often exaggerate radiation risks

Daily exposure to radioactivity is common but occurs in low doses outside of locations near nuclear accidents like Chernobyl and Fukushima. Researchers have detected radiation in tuna, bananas, and the human body due to increasing instrumental sensitivity, not rising concentrations.

Polar bears find refuge in an abandoned Russian village

Russia's Wrangel Island hosts one of the world’s largest seasonal gatherings of polar bears. Hundreds of females come ashore to den and raise cubs, often entering abandoned homes for protection. See videos and pictures of the endangered species mingling on the island.

There is a nature preserve in Korea's DMZ

In almost every way, the Demilitarized Zone is a depressing place, a testament to humans' inability to make peace. There is one surprising upside: Keeping people away has allowed nature to thrive. Recently released images offer a 360-degree view of some of the hundreds of endangered species making a comeback in the DMZ, including white-naped cranes, mountain goats, musk deer, and golden eagles.

The 'Elephant's Foot' in Chernobyl is part of the largest documented mass of corium

The nuclear disaster produced around 200 tons of nuclear fuel that mixed with the surrounding melted reactor core materials. As of 2025, corium has been naturally formed four other times in history: once during the Three Mile Island accident and three times at the Fukushima Daiichi plant disaster.

A Florida nuclear power plant canal system hosts the highest density of crocodiles in North America

Biologists have become regular fixtures at Turkey Point Nuclear Plant, where crocodiles found refuge after Florida's population boom pushed them out of coves and mangrove swamps. Teams working on the plant have done their part to modify the land and help the species thrive.

Zoo animals have developed allergies, too

Although scientists do not know if allergies manifest among wild animals—and if animals can survive with them—in a zoo setting, veterinarians have observed zoo animals with common allergy symptoms, including itchiness, crusty skin, and runny eyes. Veterinarians have identified Asian elephants with pollen allergies and at least one jaguar with an allergy to fleas.

Cold-blooded reptiles seek heat, and that behavior may help combat fungal infections

This Radiolab podcast episode takes on the idea that though our human bodies are too warm for the majority of fungal species to effectively replicate inside our bodies, that's not the case for reptiles. Yet when those species warm their bodies by basking in the sun on rocks, they can soak up heat and may also help keep fungal infections in check.

A visualization of mycoremediation, where fungi extract toxic and radioactive pollutants from soil

As organisms such as mushrooms grow, they develop large networks of root-like structures called mycelium that spread underground and release enzymes that break down contaminants. By absorbing these chemicals, fungi limit the damage caused by these toxins and localize them within the organism for easier collection and disposal.

The fragility of the alpine tundra

This article takes readers into Rocky Mountain National Park's Alpine Tundra, an area above the tree line where only specially adapted plants can survive. One such plant is the cushion plant, which avoids strong winds by growing close to the ground...

See a wild bear observe fellow bears at the zoo

At the Sequoia Park Zoo in California, a wild bear visited the bear enclosure to see three bears in captivity. Zookeepers referred to him as a "polite visitor," adding, "He stayed on the boardwalk path, kept two feet on the ground, and didn't try to climb over the railings!"

Watch how viruses like Ebola can spill over from animals to humans—and vice-versa

More than 70% of all new infectious diseases originate in animals. Referred to as zoonotic diseases, these are diseases that originate in animals and occasionally spill over or jump from animals to humans. Bats, mosquitoes, and primates have all been linked to spillover events. As human populations push further into previously uninhabited wilderness, animal-human contact increases, and disease spillover is inevitable.

Biologists believe over 5,000 coyotes inhabit LA as of 2025

Panic and fear of coyotes spread in the 1980s after the first recorded instance of a human killed by the animal in American history, but LA and Chicago residents today are learning to live alongside the animal. Research shows that coyotes can even benefit urban ecosystems by helping to control populations of geese and deer, and by improving songbird survival through preying on cats.

Larger animals like giraffes, elephants, and blue whales have developed a unique defense against cancer, a phenomenon known as Peto's Paradox

Humans were forced to adapt to survive a supervolcano eruption 74,000 years ago

The Toba supereruption ejected 2800 cubic kilometers of ash, resulting in global cooling from blocked sunlight and acid rain. Archaeological sites show that humans developed bow-and-arrow technology to survive in arid conditions by fishing in seasonal waterholes.

A list of five everyday products that rely on radioactivity, including exit signs and gemstones

Like some glow-in-the-dark wristwatches, some exit signs contain sealed tubes of tritium—radioactive hydrogen gas—which emit low-energy beta particles that react with surrounding elements to produce light, making them visible without batteries. In smoke detectors, smoke particles disrupt the steady flow of ions generated by americium-241.

The CCZ is believed to harbor trillions of dollars of valuable minerals and thousands of undiscovered species

Located between Hawaii and Mexico and spanning an area larger than the European Union, the Clarion-Clipperton Zone is the world's region with the most contracts awarded to groups seeking to extract valuable metals by collecting polymetallic nodules. Conservative estimates suggest that 21.1 billion tons of polymetallic nodules exist in this abyssal plain, but about 90% of the species in the area are unknown to scientists.

Read a technical review of extremophile categories, including the habitats of each

Acidophiles can survive in environments with acidity greater than that of the human stomach, and some radiophiles can live in places with radiation exposure hundreds of times higher than what is lethal to humans. Piezophiles—formerly known as barophiles—have been found in the Mariana Trench, where pressures are over 1,000 times larger than those on Earth's surface.

Chief scientist for project admits dire wolves aren't back

After previously announcing the deextinction of dire wolves, Colossal Biosciences' chief scientist admits they haven't done so. In an interview, they admit to having made 20 gene edits to grey wolves and applied the outdated morphological species concept—if they look like dire wolves, that is what they are.
