Archaeologists have found a trio of extraordinary stone carvings while charting the phenomenon of prehistoric rock markings in Northumberland, close to the Scottish border in the United Kingdom.

Records and examples of over 950 prehistoric rock art panels exist in Northumberland, which are of the traditional ’cup and ring’ variety, with a typical specimen featuring a series of cups and concentric circles pecked into sandstone outcrops and boulders.

However, archaeologists at the U

Maps are tools to show you where you are going, but they can also show you where you came from. That principle drives the work of Roberto Rodríguez and Patrisia Gonzales, who study ancient maps, oral traditions and the movement of domesticated crops to learn more about the origins of native people in the Americas.

“How do you bring memory back to a people that were told not to remember?” asks Rodríguez. As longtime scholars and syndicated columnists, Gonzales and Rodríguez explore this issu

’Big Bonanza’ and the Comstock Lode

Remember the burning Ponderosa map at the beginning of the long-running TV show “Bonanza”? It’s up in flames before you can read all the place names.
Now a geologist at Washington University in St. Louis has replaced that map with one of the famous ore site known as the Comstock Lode, a part of which is the “Big Bonanza.”

Did the Earth form with water locked into its rocks, which then gradually leaked out over millions of years? Or did the occasional impacting comet provide the Earth’s oceans? The Ptolemy experiment on Rosetta may just find out…

The Earth needed a supply of water for its oceans, and the comets are large celestial icebergs – frozen reservoirs of water orbiting the Sun.

Did the impact of a number of comets, thousands of millions of years ago, provide the Earth with its supply of water

Old fish bones can tell scientists about more than what people used to eat. They can also provide clues to the climate in which those people lived. In the scientific journal Quaternary Research, a team led by three University of Maine scientists reports using fish bones from an archaeological site in Peru to describe the timing of Pacific Ocean climate cycles linked to El Nino.

The report provides new evidence for a theory stating that biological cycles in the world’s oceans reflect su

For years, researchers have examined climate records indicating that millennial-scale climate cycles have linked the high latitudes of the Northern hemisphere and the subtropics of the North Pacific Ocean. What forces this linkage, however, has been a topic of considerable debate. Did the connection originate in the North Pacific with the sinking of oxygen-rich waters into the interior of the ocean during cool climate intervals, or did it originate
