Dozens of swallowtail butterflies are dancing in the air, and we pull the car over to watch. We’ve been on the road in Belize for nearly three hours with no shortage of sightseeing along the way. The drive from San Ignacio winds through San Antonio, a Maya town that is also the home of my tour guide, Israel Canto. We drive through the Mountain Pine Ridge Forest Reserve, and the deserted sustainable logging town next door. We take a pit stop to stretch our legs in a massive tunnel system–the Rio Frío Cave. Alas, we are on the final stretch, a few miles of dirt road leading to the largest Maya site in Belize–larger than its famous neighbor, Tikal in Guatemala. We are arriving at Caracol.

A laser-shooting eye in the sky has revealed the previously unappreciated size and complexity of ancient Maya civilization, both before and during its presumed heyday, scientists say.

Students in UNLV’s Magic, Witchcraft, and Religion class learn about mystical topics such as ritual magic, dream magic, vision quests and shamanism.

Ancient tools and bones unearthed in China suggest our early hominid ancestors left Africa and arrived in Asia 270,000 years earlier than previously thought.

The remains of 13 Chinese men who came to Nevada in the 1800s were reburied Tuesday after being exhumed more than two decades ago for archaeological study.

The remains of 13 Chinese men unearthed in northeast Nevada more than two decades ago will finally be reburied in the Carlin City Cemetery.

More than 1,000 years ago, the Ancestral Puebloans (also called Anasazi and Hisatsinom by the Hopi) who had thrived in the Moapa Valley area for centuries, gradually abandoned their homes and vanished into the sizzling, arid expanses southeast of Nevada.

First experts said eggs are bad for you, then they say it's OK to eat them. Is red wine good for your heart or will it give you breast cancer?
