Octopuses are among the smartest marine animals. These intelligent cephalopods are known for using coconut shells as mobile homes and armor and changing colors on demand to evade predators. A new study by researchers at Germany's Max Planck Institute of Animal Behavior found that octopuses can also be strong leaders. They take charge of hunting packs and even discipline those who try to cheat....

In the wild, animals frequently use deceptive tactics to survive. For instance, some wasps turn spiders into "zombie" slaves to build intricate nests. Similarly, mouse-eared bats mimic hornet buzzes to avoid being preyed upon by owls. Now, a new study reveals that a crafty orb-weaver spider species has found a way to manipulate the mating signals of male fireflies to catch more prey....

Food waste is a major contributor to greenhouse gas emissions. As food decomposes in landfills, it releases methane and carbon dioxide. These potent gases accelerate global warming and climate change. Experts estimate that nearly a third of the world's food, about 1.3 billion tons, is wasted annually. This waste generates a staggering 3.3 billion tons of greenhouse gases each year. It accounts for 8 to 10 percent of global emissions....

Earthworms are well-known for their ability to enrich and improve soil. Yet, their precise impact on plant growth had remained a mystery. Now, two groundbreaking studies have found that these creepy crawlers not only boost crop yields but also protect plants from harmful microplastics....

On September 26, 2024, at 11:10 pm EST, Hurricane Helene made landfall near Perry, Florida, as a dangerous Category 4 storm.

Since 2020, juvenile orcas have been intentionally colliding with boats off the coasts of Spain, Portugal, France, and Morocco. The most recent incident occurred off Spain’s northwest coast on August 25, 2024. A pod of killer whales damaged the rudder of a sailboat named the Amidala, leaving its two passengers stranded. While this boat remained afloat, the orcas' attacks have caused at least seven vessels to sink in the past four years....

Carbon dioxide (CO2), released by burning fossil fuels like oil and coal, is a large contributor to global warming. Switching to renewable energy sources like solar panels and wind turbines can help reduce the harmful emissions. However, phasing out fossil fuels entirely will take time. Meanwhile, companies like Climeworks are developing innovative solutions to reduce atmospheric CO2 levels. On May 8, 2024, the Switzerland-based startup turned on Mammoth, the world's largest direct air capture (DAC) plant....

The Big Basin Redwood State Park in Santa Cruz, California, is home to some of the tallest and oldest redwood trees on Earth. The towering trees reach heights of over 300 feet (91 m) and have an incredibly thick bark. This natural armor usually protects their upper branches and needles from wildfire damage. However, the CZU Lightning Complex Fire that burned 97 percent of the park in August 2020 was so intense that it even scorched these ancient giants....

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. This includes parts of Texas, Oklahoma, Kansas, Nebraska, South Dakota, Indiana, Missouri, Iowa, and Ohio....

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....
