Nathan Shotwell, a teacher at Holman Middle School in Glen Allen, Virginia, has been named the 2013 recipient of the Edward C. Roy Jr. Award for Excellence in K-8 Earth Science Teaching. Shotwell, who earned his Master's degree in Education from Virginia Commonwealth University, has spent his career challenging middle- and junior-high school students with what he calls "authentic problems" and inquiry-based learning in the Earth sciences.

The idea of a moon-forming collision is not new: The Giant Impact Theory put forth in the 1970s suggested that the moon resulted from a collision with a protoplanet approximately half the size of ancient Earth. But the physics underlying such a collision implied that the moon should be made up of debris mostly from the protoplanet. Since then we've discovered the moon is instead very chemically similar to Earth. Now, scientists have come up with two new models that explain how an impact could have resulted in a moon formed from Earth material.

Throughout history, humanity has steadily increased its dependence upon technology. Although technology has vastly improved the quality of life for billions of people, it has also opened us up to new risks and vulnerabilities. Terrorism and natural disasters might be at the forefront of the minds of policymakers and the U.S. population, but a significant threat lurks over our heads: the sun. A massive solar storm, the size last seen a century and a half ago, could easily leave hundreds of millions of people in the dark for days, weeks or even months.

Dr. Wayne D. Pennington, AGI Past-President, recently concluded a successful tour for the new Science, Technology and Innovation Expert Partnership (STIEP) speaker series. Part of the U.S. Department of State's Targets of Opportunity Program, the STIEP speaker series promotes science diplomacy abroad by connecting traveling scientists with local embassies and other community networks in the region. Participants have the opportunity to exponentially increase the reach of their research while simultaneously promoting key issues for science diplomacy, including the importance of innovation, the scientific peer review process, and promoting women in STEM fields. Pennington was one of the first speakers to participate in the series.

The size and type of earthquakes a given fault system may produce remain poorly understood for most major fault systems. Recent superquakes, such as the March 2011 magnitude-9 off Japan and the December 2004 magnitude-9-plus off Sumatra, have been far larger than what most scientists expected those faults to produce. The problem is that current models rely on short historical records, and even shorter instrumental records. Today, scientists are working to rewrite these models based on new paleoseismic and paleotsunami data to create a more comprehensive picture of earthquake activity through time. What they're finding might alarm you.
