Researchers have uncovered an unexpected antiviral defense system in sea anemones that works very differently from the one humans use. The discovery suggests evolution developed multiple ways to combat viruses, challenging long-held ideas about how ...
A new study reveals that goldfish can do far more than survive in the wild—they can fundamentally reshape freshwater ecosystems. Researchers found they cloud water, damage food webs, and hurt native fish populations, sometimes triggering major ...
A giant black coral estimated to be 300–400 years old has been discovered deep in Fiordland, New Zealand, astonishing researchers with its enormous size—about 4 meters tall and 4.5 meters wide. ...
Trees planted to protect farmland from wind may not be the biodiversity boost many assume. In Japan’s wetland farming landscapes, shelterbelts benefited some birds but sharply reduced grassland and wetland species that need open space. Researchers ...
Scientists discovered that Heliconius butterflies have evolved an extraordinary lifespan, living several times longer than closely related species. Even more surprising, some show little sign of physical decline as they age. Their unusual ...
Freshwater lakes across North America and Europe are becoming noticeably browner, reducing underwater visibility and reshaping fish populations. Research found that several popular sport fish, including trout, bass, perch, and whitefish, tend to ...
Scientists have digitally preserved the world’s most endangered marine mammal by creating highly detailed 3D models of a vaquita skeleton using advanced imaging technology. The virtual archive provides an unprecedented look at the species and ...
A surprising new discovery suggests that tiny microbes living inside fish may be helping shape the chemistry of the world’s oceans. Scientists found evidence that bacteria in the guts of marine fish work alongside their hosts to produce calcium ...
Scientists have uncovered an astonishing new chapter in humpback whale migration: two whales were found to have traveled between breeding grounds in Australia and Brazil, crossing more than 14,000 kilometers of open ocean. One whale shattered ...
Scientists exploring deep underwater canyons off the coast of Western Australia uncovered a hidden world packed with bizarre and elusive marine life — including signs of the legendary giant squid. By analyzing traces of DNA floating in seawater ...
Researchers created a special kind of algae that can grab microscopic plastic pollution out of water almost like a magnet. The algae produce limonene, an orange-scented oil that helps them bind to water-repelling microplastics, forming ...
Beneath the beauty of coral reefs lies a hidden universe of microbes unlike anything scientists expected. Each coral species supports its own specialized microbial partners, many of which have never ...

A hidden crater in South Korea may hold clues to one of the biggest turning points in Earth’s history: the rise of oxygen. Scientists discovered fossil-like stromatolites — layered structures ...

Scientists revisiting mysterious 540-million-year-old microfossils from Brazil have overturned a major idea about early animal life. What were once thought to be trails left behind by tiny worm-like ...

Fur seals may look like they’re simply resting after exhausting hunting trips at sea, but their bodies are secretly working overtime. Scientists discovered that hours after returning to land, the ...

Scientists have peered inside the skull of a 380-million-year-old Antarctic fish that was closely related to the first animals to walk on land, revealing surprising clues about how life began its ...

Giant, fearsome octopuses may have once ruled the ancient seas, according to new research that flips the script on their evolutionary past. By uncovering exquisitely preserved fossil jaws hidden ...

A mysterious “golden orb” found more than two miles deep in the Gulf of Alaska left scientists baffled for over two years, sparking wild speculation about its origins. After an intensive ...

A vivid green pitviper hiding in Sichuan’s misty mountains has been revealed as a completely new species. Scientists had overlooked it for decades, assuming it was a common snake—until DNA ...

Crabs’ famous sideways walk may trace back to a single evolutionary moment 200 million years ago. Researchers found that most modern crabs inherited this trait from one ancestor—and never looked ...

Some of the ocean’s fastest and most fearsome predators—like great white sharks and tuna—are running hotter than expected, and it’s costing them dearly. New research shows these warm-bodied ...

A badly mangled dinosaur skull, once forgotten in a drawer, turned out to be a rare and important discovery. Reconstructed by a Virginia Tech student, it revealed a new species of early carnivorous ...

In the Arizona desert, scientists have uncovered a bizarre and almost unbelievable partnership between ants: tiny cone ants acting as “cleaners” for much larger harvester ants. Instead of ...

Gray whales are beginning to break their long-established migration patterns, venturing into risky new territory like San Francisco Bay as climate change disrupts their Arctic food supply. But this ...

Dragonflies may see the world in a way that pushes beyond human limits—and surprisingly, they do it using the same molecular trick we evolved ourselves. Scientists discovered that these insects can ...

Scientists found that storing mangoes at 54°F dramatically slows ripening and keeps the fruit fresh far longer than typical tropical temperatures. The cooler conditions helped mangoes stay firm, ...

Asteroid impacts may have helped kick-start life on Earth by creating hot, chemical-rich environments ideal for early biology. These impact-generated hydrothermal systems could have lasted thousands ...

A remarkable fossil discovery in southwest China is rewriting the story of how complex animal life began, showing that many key animal groups appeared millions of years earlier than scientists once ...

Scientists have finally cracked a long-standing mystery about squid and cuttlefish evolution by analyzing newly sequenced genomes alongside global datasets. The research reveals that these bizarre, ...

Ancient Earth once buzzed with enormous dragonfly-like insects, and scientists long thought high oxygen levels made their size possible. A new study overturns that idea, revealing insect flight ...

A sweeping global report finds that migratory freshwater fish are in steep decline, with populations down roughly 81% since 1970. These species depend on long, connected rivers, but dams and human ...

In a remarkable deep-sea breakthrough, researchers have discovered 24 new species of amphipods in the Pacific’s Clarion-Clipperton Zone—including a rare, entirely new superfamily. The findings ...
