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

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

SMU 2015 research efforts broadly noted in a variety of ways for world-changing impact

SMU scientists and their research have a global reach that is frequently noted, beyond peer publications and media mentions.

It was a good year for SMU faculty and student research efforts. Here’s a small sampling of public and published acknowledgements during 2015, ranging from research modeling that made the cover of a scientific journal to research findings presented as evidence at government hearings. Continue reading
