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 pollen ...

Tyrannosaurus rex may have been a much slower grower than scientists realized. A new study of 17 tyrannosaur fossils found that the giant predator likely took about 40 years to reach its full size of roughly eight tons, extending previous estimates . ...

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 ...

Despite centuries of study, scientists are still finding new details and even overlooked structures within the human body. As researchers explore anatomical differences between individuals, it's becoming clear that the body is far more complex--and . ...

A surprising new study suggests the earliest primates didn't originate in tropical forests but in cold, dry parts of North America. Some may have even survived seasonal Arctic conditions by slowing their metabolism or hibernating. Researchers found . ...

Scientists found that thawing permafrost can trigger increased rock weathering, a natural process that absorbs CO2 from the atmosphere. In some regions, this carbon uptake was strong enough to fully offset -- or even surpass -- river greenhouse gas . ...

Animals from different species often rely on surprisingly sophisticated communication to work together, whether finding food, cleaning parasites, or gaining protection. New research suggests these interspecies "conversations" are flexible, evolved, . ...

A new biomaterial made from jackfruit latex, pomegranate peel, and simvastatin could transform the treatment of severe gum disease. Early tests suggest it not only combats infection and inflammation but may also help rebuild lost bone and tissue ...

Researchers have created a new way to reconstruct the evolutionary history of complex plant genomes by analyzing genetic traces left by transposable elements. The technique revealed that modern strawberries were assembled through multiple ancient ...

A new study suggests Southern California's major fault system is more stressed than at any point in the last 1,000 years. Researchers found that the Cajon Pass, where the San Andreas and San Jacinto faults meet, could act as an "earthquake gate" that ...
