Tardigrades, or water bears, are virtually indestructible. The eight-legged microscopic animals can withstand extreme temperatures, survive without food for decades, and even exist in a vacuum in space. But, despite being around for over 500 million years, they rarely appear on the fossil record. Their miniature size and lack of hard tissue make it hard for them to fossilize. Even when they do get preserved, the tiny creatures are hard to spot and often get overlooked. Over the years, only two tardigrade fossils have been found. Now, a third specimen — one of a new tardigrade species — has joined this exclusive group....

Every October, families rush to pumpkin patches to pick out the perfect gourds. Some use them to carve spooky jack-o'-lanterns, while others place them outside their homes as decor. Unfortunately, the fascination with the colorful fruit fades once Halloween ends, and most pumpkins end up in the trash....

A ruptured undersea oil pipeline off the coast of Huntington Beach, CA, has leaked thousands of gallons of oil into the Pacific Ocean, threatening fish and wildlife and causing numerous beach closures. The spill, caused by a 13-inch tear in a pipeline that transports crude oil from an offshore drilling platform to a pump station in Long Beach, CA, was first reported by locals on October 1, 2021. Experts are still trying to determine the amount of oil leaked before the pipeline was shut down on October 3, 2021. The estimates range anywhere from 25,000 gallons to 136,000 gallons....

Most seafood lovers — animal or human — would find it hard to resist a tasty shrimp morsel. However, not Kit, a mischievous sea otter that resides at California's Monterey Bay Aquarium. Rather than gulping down the tiny crustacean, Kit used it as a game piece to play what the aquarium officials dubbed "The Shrimp Game."...

When some curious summer campers at the Hamilton Junior Naturalist Club (Junats) set out on an expedition to Kawhia Harbour on New Zealand's North Island, they were just hoping to find some small crustacean fossils. Instead, they discovered a well-preserved skeleton of a new species of a giant penguin that inhabited the area between 27 to 30 million years ago....

La Palma, one of Spain's Canary Islands, has been feeling the wrath of the Cumbre Vieja volcano since September 19, 2021. The explosive volcano, which came to life shortly after 3:00 pm local time, has been spewing out large amounts of molten lava, sometimes up to 20 feet (6 meters) high. The slow-moving rivers of magma have destroyed nearly 400 homes, buried dozens of kilometers of roads, and consumed hundreds of acres of farmland....

The school day had just ended at Isaac Dickson Elementary School in Asheville, North Carolina. Most students had left, and the ones in the school's "supervised homework help" program were inside the campus. Fifth-grade teacher Betsie Stockslager Emry was also heading home when she noticed two playful black bears entering the empty playground. What happened next will bring a smile to your face....

The Sequoia National Park in California's southern Sierra Nevada mountains is best known for its namesake giant sequoias. The park boasts 40 groves of the massive trees, which occur naturally only on its western slopes. But the most beloved is the Giant Forest, a collection of 2000 trees that includes half of the Earth's largest and longest-living trees. This past weekend, the ancient wonders came dangerously close to being scorched by the KNP Complex Fire. But thanks to quick-thinking firefighters, the precious grove has been saved....

After years of intense public pushback, the now-shuttered Ringling Bros. and Barnum & Bailey Circus finally announced the retirement of their Asian elephant performers in 2016. While the decision was a resounding victory for animal lovers and activists, it raised a new issue. The mighty pachyderms were raised in captivity and lacked the skills to survive in the wild. Now, thanks to Florida-based White Oak Conservation, the animals have a new home — one where they can roam freely....

The western false asphodel — an herb-like plant found in abundance along North America's West Coast — has been known to science since 1879. But it is only recently that researchers from the University of British Columbia discovered the innocent-looking plant's penchant for insects. The finding is particularly exciting given that this is the first new predatory plant to be discovered in 20 years....

The Henan Province in central China is a treasure trove of dinosaur eggs. However, the odd-looking black orb with a blue tint, presented to Fenglu Han and Haishui Jiang by a farmer in 2018, was unlike any dinosaur egg the experts had encountered before. The paleontologists from the China University of Geosciences initially thought the egg might belong to a new species of the prehistoric giants....

The 2021 Atlantic hurricane season began with a bang for the residents of Louisiana. On August 29, 2021, the Gulf Coast state was battered by Hurricane Ida, a powerful Category 4 storm that officials believe was the strongest to hit the area in 165 years. To make matters worse, Ida arrived on the sixteenth anniversary of the devastating Hurricane Katrina and made landfall twice....

Clothing made from synthetic materials, such as polyester and nylon, has many positive attributes. It is cheap to produce, lasts for a long time, and is comfortable to wear. However, the fabric, made from petroleum, has one major downside. The tiny polymer strands — or what we call lint — that shed from the textiles during each laundry cycle are big contributors to plastic pollution. Now, some scientists from Lithuania have found a way to recycle the textile waste into clean energy....

On August 8, 2021, the United Nations' Intergovernmental Panel on Climate Change (IPCC) released its first assessment of climate science since 2013. The news was not good. The report stated that this past decade was the hottest in 125,000 years and that the atmospheric carbon levels are the highest in at least 2 million years. Glaciers are melting faster than any time in over 2,000 years, and ocean levels are rising at twice the rate since 2006....

Antarctica is surrounded by icebergs. However, the finger-shaped chunk of ice that recently broke loose from the western side of the Ronne Ice Shelf — one of the world's most extensive ice platforms — is worthy of a mention. Measuring approximately 105 miles (170 km) long and 15 miles (25 km) wide, it boasts a surface area of 1,660 sq miles (4,300 sq km) and is currently the world's largest iceberg....

When Jennifer Johnson and her team embarked on their annual quest to survey the sturgeon population in the Detroit River in mid-April 2021, they had fully expected to find some super-sized specimens. However, the U.S. Fish and Wildlife Service biologists had never anticipated luring in the granddaddy of all sturgeons — a massive, 240-pound, 6-foot, 10-inch long fish that they estimate is at least a century old!...

The annual 3-to 4-millimeter rise in sea levels is expected to impact many coastal communities in the coming decades. However, few are as vulnerable as the Republic of the Maldives, a collection of more than a thousand picturesque islands in the Indian Ocean. NASA researchers believe that parts of what is "arguably the lowest-lying country in the world" will become uninhabitable by 2050, due to wave-driven flooding and limited freshwater. To combat the inevitable, the government recently unveiled plans for the world's first "true" floating island city....

British sculptor Jason deCaires Taylor has made it his mission to use his talent to conserve our ecosystems by creating underwater museums. Over the years, the environmentalist has submerged over 850 massive artworks in numerous site-specific "sculpture parks" worldwide. On February 1, 2021, Taylor unveiled his latest endeavor — The Underwater Museum of Cannes....

Regeneration, or the ability to regrow body parts, is a fairly widespread phenomenon in the animal kingdom. However, the skill is usually restricted to growing a new tail or a new limb. Now, researchers have found two species of sacoglossan sea slugs — Elysia atroviridis and Elysia marginata — that deliberately detach their heads from their original bodies and grow brand new ones!...

Fifteen US states, including New York, Illinois, Georgia, Virginia, Maryland, New Jersey, as well as Washington D.C., will soon be buzzing with billions, and perhaps even trillions, of cicadas. The noisy, red-eyed members of Brood X, which have been hibernating underground for the past 17 years, will emerge unannounced as soon as the conditions are right: the soil is 64 degrees, and on a night that's humid enough but free of wind and rain....

Though it is not unusual to find marine animals thriving under the Antarctica seafloor, researchers had always assumed that all life would become less abundant farther away from open water and sunlight. However, the discovery of filter-feeding organisms — 160 miles (260 km) away from the open ocean, with temperatures of −2.2°C and under complete darkness — suggests that life in the world's harshest environment may be more adaptable and diverse than previously thought....

King penguins, the second-largest penguin species, typically sport a distinct black-and-white coat with a yellowish-gold dash of color on their collar. However, one young penguin in the South Atlantic appears to have missed the memo on the dress code. It decided to forgo the black feathers and retain just the bright yellow plumage....

In 2011, conservationists moved eight Rothschild's giraffes to Longicharo Island, a rocky peninsula on Lake Baringo in Western Kenya. The scientists hoped the isolated area would save the endangered animals from poachers and allow their numbers to multiply. However, intense rainfall in August 2020 caused the lake water levels to rise substantially, cutting the area off from the mainland and reducing the once lush, 100-acre habitat to about eight acres....

Madagascar, an island off the coast of Africa, is home to some of the world's most exciting and unique animal species — about 75 percent of which cannot be found anywhere else on the planet. These include the long-necked giraffe weevil, the colorful, cat-sized panther chameleon, and the bright orange-red tomato frog! The latest to join this impressive list of exotic creatures is a new reptile species small enough to perch on the tip of a finger!...
