Warming across the U.S. is far more uneven than it looks at first glance. While only about half of states show rising average temperatures, most are heating up in specific ways--like hotter highs or warmer lows. These hidden shifts vary by region, .. ...

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 of years--long enough for life's building blocks to ...

Saturn's magnetic field isn't the smooth, symmetrical shield scientists see around Earth. Instead, it's noticeably skewed, and researchers now think they understand why. By analyzing years of data from the Cassini spacecraft, scientists found that a ...

What started as routine fossil cleaning turned into a major scientific surprise when researchers uncovered a tiny claw in a 500-million-year-old specimen where no claw should exist. That detail revealed Megachelicerax cousteaui, the oldest known ...

Thousands of years ago in a cave on Hispaniola, an unusual chain of events left behind a rare scientific treasure: bees nesting inside fossilized bones. After giant barn owls repeatedly brought prey like hutias into the cave, their remains ...

A puzzling wrinkled rock formation in Morocco has led scientists to rethink where ancient microbes could live. Instead of shallow, sunlit waters, these microbes may have thrived deep in the ocean, fueled by chemicals delivered by underwater ...

Hundreds of millions of years ago, Earth's magnetic field behaved in a way that has long baffled scientists, showing wild and seemingly chaotic shifts unlike anything seen before or since. A new study suggests this chaos may actually hide a deeper .. ...

More than 12,000 years ago, Native American hunter-gatherers were already making and using dice--thousands of years before similar tools appeared elsewhere. These bone "binary lots" acted like primitive coins, producing random outcomes for games of . ...

A mysterious Greek inscription found beneath the Great Mosque of Homs could pinpoint the long-debated location of an ancient sun temple. Scholars now think the mosque sits atop a sacred site that transitioned from pagan worship to Christianity and .. ...

High in a South American rainforest canopy, scientists have discovered a bizarre new termite species that looks strikingly like a miniature sperm whale. Named Cryptotermes mobydicki, this tiny insect has an elongated head and concealed mandibles that ...
