One of the most significant Etruscan discoveries in decades names female goddess Uni

Etruscan, stele, Uni, goddess, Poggio Colla, Italy, Gregory Warden, SMU, Mugello Valley ProjectArchaeologists translating a very rare inscription on an ancient Etruscan temple stone have discovered the name Uni — an important female goddess.

The discovery indicates that Uni — a divinity of fertility — may have been the titular deity worshipped at the sanctuary of Poggio Colla, a key settlement in Italy for the ancient Etruscan civilization, said archaeologist Gregory Warden at SMU, main sponsor of the archaeological dig.

Textbook theory of how humans populated America is “biologically unviable,” study finds

The established theory of how Ice Age peoples first reached the present-day United States is now challenged by an unprecedented study that concludes that entry route was “biologically unviable.”

The North American ice-free corridor, thought to have been used by the first colonizers, only became biologically viable 12,600 years ago — after they would have arrived. Researchers suggest a Pacific coast was the entry route.

Students grasp abstract math concepts after they demonstrate them with arm motions

Walkington, SMU, geometry, proof, arm motions Students who make relevant arm movements while learning can improve their knowledge and retention of math, research has shown.

Now researchers at Southern Methodist University, Dallas, and the University of Wisconsin-Madison have developed a model using geometry proofs that shows potential for wide adoption — a video game in which students make movements with their arms to learn abstract math concepts. Continue reading

Geohazard: Giant sinkholes near West Texas oil patch towns are growing — as new ones lurk

Two giant sinkholes that sit between two West Texas oil patch towns are growing — and two new ones appear to be lurking, say geophysicists at Southern Methodist University, Dallas. Satellite radar images reveal substantial ground movement in and around the infamous sinkholes near Wink, Texas — suggesting expansion of the two existing holes, with subsidence in two other nearby areas suggesting new ones may surface.

17 million-year-old whale fossil provides 1st exact date for East Africa’s puzzling uplift

Whale, fossil, kenya, Great Rift, Africa, Jacobs, WichuraUplift associated with East Africa’s Great Rift Valley and the environmental changes it produced have puzzled scientists for decades because the timing and starting elevation have been poorly constrained.

Now paleontologists have tapped a fossil from the most precisely dated beaked whale in the world — and the only stranded whale ever found so far inland on the African continent — to pinpoint a date when the mysterious elevation began. Continue reading

SMU analysis of recent North Texas earthquake sequence reveals geologic fault, epicenters in Irving and West Dallas

Locations of seismic instruments as of Jan. 30, 2015, with revised earthquake locations in dark red. (USGS)Initial results from the seismology team at Southern Methodist University reveal that a recent series of earthquakes near old Texas Stadium in the Dallas-Fort Worth area were relatively shallow and concentrated along a narrow two-mile line that indicates a fault extending from Irving into West Dallas. SMU and the United States Geological Survey have shared an interim report with the mayors of Dallas and Irving. Continue reading

Scientists issue call to action for archaeological sites threatened by rising seas, urban development

Western%20Site%20Margin%20400x300.jpgShould global warming cause sea levels to rise as predicted in coming decades, thousands of archaeological sites in coastal areas around the world will be lost to erosion.

With no hope of saving all these sites, an SMU archaeologist and others call for scientists to assess the sites most at risk.
