Smithsonian: Ancient Volcanoes May Have Shifted the Moon’s Poles

moon_poles_shift.jpg__800x450_q85_crop_upscaleScience reporter Danny Lewis with Smithsonian covered the research of SMU planetary scientist and research assistant professor Matthew Siegler and a team of scientists who discovered the moon wandered off its axis billions of years ago due to a shift in its mass most likely caused by volcanic activity.

The article, “Ancient Volcanoes May Have Shifted the Moon’s Poles,” published March 24. A report on the discovery of the rare event was published today in Nature: that Earth’s moon slowly moved from its original axis roughly 3 billion years ago. Continue reading

NASA data leads to rare discovery: Earth’s moon wandered off axis billions of years ago

Ancient lunar ice indicates the moon’s axis slowly shifted by 125 miles, or 6 degrees, over 1 billion years. Earth’s moon is now a member of solar system’s exclusive “true polar wander” club, which includes just a handful of other planetary bodies. Planetary scientist Matt Siegler at Southern Methodist University, Dallas, and colleagues made the discovery while examining NASA data known to indicate lunar polar hydrogen. Continue reading

Good news! You’re likely burning more calories than you thought

Counting calories burned is popular, but leading standardized equations used to predict or estimate calories burned while walking assume that one size fits all. They’ve been in place for close to half a century and were based on data from a limited number of people.

A new SMU study found that under firm, level ground conditions, the leading standards are relatively inaccurate and have significant bias — predicting too few calories burned in 97 percent of cases researchers examined.

New look at Pizarro’s conquest of Inca reveals foot soldiers were awed by empire’s grandeur

Spanish conquistador Francisco Pizarro’s 1532 attack on the Inca empire during a two-day conflict in Cajamarca, Peru is an infamous episode in history.

Long-term daily contact with Spanish missions triggered collapse of Native American populations in New Mexico

New research in the Southwest U.S. has resolved long-standing debates on the timing and magnitude of American Indian population collapse in the region.

The severe and rapid collapse of Native American populations in what is now New Mexico didn’t happen upon first contact with Spanish conquistadors in the 1500s. Nor was it as gradual as others had contended. Continue reading
