Elephants are known for their exceptional intelligence, empathy, and communication skills. A new study suggests they may have another remarkable ability: assigning individual "names" to each other. The mammals are the first non-human species to exhibit this unique capability....

The Thwaites Glacier in West Antarctica is the world's largest and widest glacier. The massive ice sheet stretches 80 miles (129 km) across, roughly the size of Florida. The glacier loses about 50 billion tons of ice annually and already accounts for about 4 percent of the planet's current sea level rise. If it were to melt completely, it could raise global sea levels by about two feet (61 cm). This would displace millions of people in coastal communities worldwide. It is no wonder the ice mass has been nicknamed "Doomsday Glacier."...

Orcas, also known as killer whales, are the largest members of the dolphin family. The mammals hunt in pods of up to 40 individuals. They are known for their coordinated attacks on marine animals. But the whales rarely pose a threat to humans....

Rising sea levels, fueled by global warming, are escalating at an alarming rate, putting coastal communities worldwide at risk. By 2050, experts predict that nearly 300 million people living in coastal areas will face annual flooding. Japan's N-Ark hopes to combat the impact of climate change with an innovative floating city....

Tornadoes can strike the United States year-round, but they are most active from March to July. While they occur nationwide, a region known as "Tornado Alley" is the most susceptible to the twisters.

Environmental scientists Shi-Mao Wu and Jiang-Yun Gao were in a rainforest in China's Yuan Province when they noticed mosquitos buzzing around some flowers. Upon looking closer, the researchers realized they were looking at a male and a female crab spider. They had come together to resemble a single flower. The male spider was disguised as the pistils and stamens, while the female looked like the flower's lighter petals....

Celebrated every April 22, Earth Day is an annual reminder of the urgent need to protect our planet. The global movement began on April 22, 1970, when US lawmaker Gaylord Nelson mobilized more than 20 million people to demonstrate support for environmental protection....

A new species of ragworm, likened to a living magic carpet, has been discovered in the methane seeps 30 miles (48 km) off the coast of Costa Rica. The rose-colored Pectinereis strickrotti (P. strickrotti) is one of 450 species found in the area since 2009. Forty-eight of them are new to science....

Every spring, many fish species migrate from the Vecht, a branch of the Rhine River, to the shallow waters of the Kromme Rijn River to spawn and reproduce. However, their journey often stops at the Weerdsluis lock in Utrecht, Netherlands. The manually operated lock, designed to maintain the canal's water levels, rarely opens in the spring months. But now, thanks to an interactive "fish doorbell," the marine animals are able to reach their destination with little or no disruption....

Earth Hour 2024 will occur on March 23 from 8:30 pm to 9:30 pm local time. The event, held annually toward the end of March, encourages individuals, communities, and businesses worldwide to turn off non-essential electric lights for one hour. The voluntary rolling blackouts are also observed by landmark structures such as the Eiffel Tower and the Empire State Building. They remind us of the urgent need to protect our planet....

Firefighters in Texas are battling a number of wildfires in the state's northernmost area called the Panhandle. The destructive blazes have scorched over a million acres, killed thousands of cattle, and charred crops. The fires have burned over 500 structures, melted lamp posts, and split power lines in half. Two residents have been killed, four firefighters injured, and thousands evacuated....

On February 27, 2024, biologists at San Francisco's California Academy of Sciences revealed that "Mirage," its resident titan arum, or corpse flower, had bloomed. The massive plants bloom once every seven to ten years. The flowers last just one to three days and emit a pungent odor reminiscent of rotting flesh. It is no wonder that titan arums are deemed the "world's stinkiest flower."...

California's Yosemite National Park is famous for its giant, ancient sequoia trees and impressive rock formations. They include El Capitan and Half Dome. But from mid to late February, the park's main attraction is Horsetail Fall, located at the edge of the eastern side of El Capitan. During this time, the setting Sun hits the seasonal waterfall at just the right angle, creating the illusion that it is on fire....

The world's largest iceberg is on the move after being stuck to the ocean floor for 37 years. A23a stretches almost 1,500 square miles (3,885 sq. km) wide, or about three times the size of New York City and its five boroughs. The massive slab of ice weighs over one trillion tons and stands 1,313 feet (400 m) tall. For comparison, the Empire State Building measures 1,250 feet (380 m) from top to bottom....

With heavy hearts, officials at the Smithsonian's National Zoo in Washington, DC, have bid farewell to its three resident giant pandas. Mei Xiang, 25, Tian Tian, 26, and their 3-year-old son, Xiao Qi Ji, left for China aboard a retrofitted Boeing 777 aircraft on November 8, 2023. Upon reaching Chengdu on November 9, 2023, the trio was whisked away to the Wolong Panda Center. After a 30-day quarantine, the mammals will be allowed to mingle with the 150 wild giant pandas at the nature reserve....

Plastic pollution gets a lot of attention. However, the ever-increasing pile of discarded electronics is not as well-publicized. In 2014, over 49 million tons of toxic "e-waste" ended up in landfills. This includes computers, smartphones, and televisions. If left unchecked, the number is expected to increase to 82 million tons by 2030. Envision Racing hopes to raise awareness about the urgent need to recycle and repurpose our gadgets with a racing car made entirely from e-waste....

This year's summer was the Earth's hottest since global record-keeping began in 1880. Large parts of the Northern Hemisphere – including areas of the United States, Europe, and Japan – experienced scorching heatwaves. Humans comfortably rode out the extreme weather inside air-conditioned homes and offices. However, the option was not available to most zoo animals. Here are some creative ways that zookeepers used to keep the animals safe in the heat....

The ocean is full of mysteries. But few have grabbed the attention of the scientific community and the public as the recently-found "golden egg." Researchers from the National Oceanic and Atmospheric Administration (NOAA) stumbled upon the shiny orb two miles (3.2 km) deep in the Gulf of Alaska on August 20, 2023....

Found in tropical waters worldwide, trumpetfish are elongated creatures with long snouts, which they use to swallow small fish and shrimp. The large fish are known to use a variety of tactics to avoid being detected by their prey. They include changing color to blend in with their surroundings and hiding amid the long branches of soft corals. Now, researchers have found that the crafty fish often deceive their prey by hiding behind larger, friendlier fish....

Instead, she has a plain brown coat. The zoo's officials believe she might be the "only solid-colored reticulated giraffe living anywhere on the planet."...

If this summer feels a little warmer than usual, you are not wrong. The global temperatures in June 2023 far exceeded the previous record set in June 2019. The sweltering weather intensified in July. On August 14, 2023, NASA reported that it was the hottest month since global temperature record-keeping began in 1880. Some experts believe July may have been the hottest month in 120,000 years. If the trend continues into the fall and winter, 2023 may surpass 2016 as the hottest year on record....

On June 21, 2023, the US Department of Agriculture (USDA) granted its first-ever approval of cell-cultured meat. The assent is restricted to products made by GOOD Meat and UPSIDE Foods. It was the final step the California-based startups needed to sell their lab-grown chicken in the US....

There are over 30 meteor showers annually. But few can compare to the spectacular Perseids. The "shooting stars" have been blazing through the sky at a rate of about a dozen an hour since mid-July and will continue until the end of August. But the best time to view them is when Earth passes through the area with the densest comet dust. That's when the meteors' pace increases to between 50 and 100 an hour. This year that will be during the pre-dawn hours of August 13....
