Pando is a giant aspen clone in central Utah that has been regrowing parts of itself for up to 80,000 years — but new threats mean the plant is now in decline.

Startup Clone Robotics has created an ultra-creepy humanoid torso with artificial muscles that are activated through a battery-powered hydraulic system and covered in ghostly-white "skin."

Vietnam's Son Doong cave is so large, you could squeeze 15 Great Pyramids of Giza inside it and fly a Boeing 747 airplane through some of its passages.

Global warming during the Last Interglacial period caused so much Arctic ice to melt that Atlantic currents collapsed — and scientists say these are the conditions we could be heading toward.

A new U.N. report has found the world will warm by twice the 1.5-degree-Celsius target adopted in the Paris Agreement by 2100 if countries fail to slash greenhouse gas emissions right now.

In a new peer-reviewed study, Ne'Kiya Jackson and Calcea Johnson outlined 10 ways to solve the Pythagorean theorem using trigonometry, including a proof they discovered in high school.

Population assessments have revealed that polar bears in Greenland are suffering from crippling wounds on their paws due to wet snow that gets stuck to the pads and freezes into blocks.

Icebergs and other glacial fragments regularly wash up on Iceland's southern Diamond Beach, making the sandy strip look like a field of gemstones.

Geoenvironmental scientist Hiroto Nagai used publicly available climate data from the North and South poles to compose an ominous-sounding chamber music piece.

A fiery meteor shot across the sky above the Great Lakes on Monday (Oct. 21) just after sunset, stunning witnesses from Michigan to New York, Kentucky and North Carolina.

Leading climate scientists ring alarm bell on key Atlantic Ocean current collapse in open letter

Carlsbad Caverns National Park in southeastern New Mexico is home to 119 known caves, including North America's largest cave chamber, the Big Room.

Researchers working with Colossal Biosciences have assembled a near-complete Tasmanian tiger genome and developed artificial reproductive technologies that could help de-extinct the species.

Researchers have discovered enormous tube worms and other creatures thriving in cavities beneath the seafloor on the East Pacific Rise, an ocean ridge near the Galápagos Islands.

Inside a basilica in Turkey, researchers have unearthed a bone-filled tomb that may have belonged to a Roman gladiator named Euphrates and was later repurposed for a dozen people.

Researchers created a seismic map of Earth's interior beneath the southeastern Pacific Ocean and discovered an ancient slab of oceanic crust that appears to be stuck midway through the mantle.

Scientists first described the flooded cave in 2016 but determined its extraordinary extent years later.

A new physical model suggests meltwater from thawing permafrost on Russia's Yamal Peninsula can unlock methane sources at depth, triggering explosions that open enormous craters at the surface.

Researchers found the carcass in August 2020 in Russia's Sakha Republic, and the discovery has revealed a never-before-seen characteristic of woolly rhinos: a fatty hump on the animal's back.

Researchers recently surveyed the bottom of Lake Michigan after spotting strange circles on the lakebed in 2022. New observations show the circles are craters, but how they formed remains unclear.

Every year, record-seeking surfers and spectators descend on the small Portuguese town of Nazaré for the "big wave" season, when water can surge up to 100 feet (30 meters) tall.

While exploring the Tonga Trench in the Southwestern Pacific Ocean, researchers captured extremely rare footage of a Magnapinna squid with arms several times the length of its body.

A boom in vegetation at the end of the last ice age may have created so much pollen, it blocked mammoths' sense of smell. A new study suggests this drove the beasts to extinction, but not everyone agrees.

The Antarctic ozone hole usually starts forming in early August, but rare warming events and a strangely elongated polar vortex this year may have delayed its arrival.
