A major study shows complex cells evolved gradually in an oxygen-poor world, challenging long-held assumptions about life’s ...

Conventionally, the moon is thought to have formed during one big impact, but a three-impact model might make more sense ...

The explosive supernova deaths of nearby massive stars may have played a significant role in triggering at least two mass extinction events in Earth's history, according to new research. As some of ...

Earth held a deep ocean of magma beneath its surface in its early history, new research finds, potentially explaining odd anomalies seen in the mantle today. This basal magma ocean has been hotly ...

Researchers have made a new discovery that changes our understanding of Earth's early geological history, challenging beliefs about how our continents formed and when plate tectonics began. A study ...

A new analysis of computer simulations of Earth’s magnetic field suggests that its behavior was different early in Earth’s history, resulting in greater stability and fewer reversals of the magnetic ...

A rocky outcrop in a remote corner of northern Quebec appears serene in its eerie isolation on the eastern shore of Canada’s Hudson Bay. But over the past two decades, this exposed remnant of ancient ...

A new study traces a 120-million-year-old 'super-eruption' to its source, offering new insights into Earth's complex geological history. Geologists led by the University of Maryland and the University ...

(THE CONVERSATION) If pollen allergies are getting to you, you are not alone. Every year, plants release billions of pollen grains into the air, specks of male reproductive material that many of us ...

Our species likes it cold. Homo sapiens evolved in — and still inhabits — one of Earth’s rare and fragile ice ages, periods distinguished not by an abundance of saber-toothed cats and woolly mammoths ...

For National Snail Day, museum research fellow Melissa Betters explores the mollusks’ notable nature Melissa Betters A shell from the Cuvier tropid snail, a terrestrial species native to Madagascar, ...

Modern continental rocks carry chemical signatures from the very start of our planet's history, challenging current theories about plate tectonics. Researchers have made a new discovery that changes ...
