...but it isn't. Beneath the Taiwan Strait, scientists have discovered an underwater geological formation that closely resembles a fortress wall. It's not Atlantis, either.

A landslide in northern Guatemala buried dozens of people Sunday. Between 40 and 60 people are still missing.

One frigid night in 1961, on a remote patch of desert about 65 kilometers east of Idaho Falls, a nuclear reactor exploded. Three men were killed in the nation’s only fatal nuclear accident.

Tiny nanoparticle-sized diamonds found in sediments dating to 13,000 years ago may hold a clue to why North America's mammoths disappeared about that time. The tiny gems suggest a cosmic impact, scientists say, that may have ultimately been behind the extinctions.

A series of minor earthquakes has shaken up Yellowstone National Park over the past week. Although scientists say the swarm probably doesn't foreshadow a volcanic eruption, they are keeping a close watch over the region.

At about 4,500 years old, Stonehenge is the world’s most iconic and mysterious prehistoric ruin, and archaeologists and geologists still wrangle over the origin of some of Stonehenge's stones: Did humans transport them hundreds of kilometers to southern England? Or were glaciers responsible, acting as a kind of natural conveyor belt?

Salt from Utah's Great Salt Lake makes for fluffier snow over Colorado's slopes.

After three and a half years of continuous eruption, the volcano has — for now — quieted.

Climate change policy isn't just about science — it has to consider economics, legal and social issues. By glossing over those, researchers say, scientists are having trouble getting their message across.

A new U.S. Climate Change Science Program report states that abrupt climate change is unlikely to happen over the next century, scientists announced Tuesday at the annual meeting of the American Geophysical Union. But the consequences could still be severe.

At the bottom of a geothermal well, engineers unexpectedly drilled straight into molten magma.

According to EIA's latest Short-Term Energy Outlook report, the global demand for oil dropped dramatically this year — but will plunge even further next year.

The Aborigines regard Australia’s unique, beautiful geological formations as sacred and mystical. But geologists can also take pleasure in the geological mysteries of the Land Down Under, each of which has its own story to tell.

In 1984, nearly half a million people in Bhopal, India, were exposed to a toxic gas that had leaked from a nearby Union Carbide pesticide plant. Thousands died. And as the effects of the poison linger in the groundwater, court cases against the company are still dragging on.

Taxonomist Linneaus applied his classification system not only to living creatures but also to minerals. Although counterintuitive — iron doesn't have genes! — scientists say Linneaus may have been on to something: Like living organisms, minerals have evolved considerably over the course of Earth’s history.
