Background:

Volcán Popocatépetl, whose name is the Aztec word for smoking mountain, towers to 5426 m 70 km SE of Mexico City to form North America’s 2nd-highest volcano.  The glacier-clad stratovolcano contains a steep-walled, 250-450 m deep crater.  The generally symmetrical volcano is modified by the sharp-peaked Ventorrillo on the NW, a remnant of an earlier volcano. 
At least three previous major cones were destroyed by gravitational failure during the Pleistocene, producing massive debris-avalanche deposits covering broad areas south of the volcano.  The modern volcano was constructed to the south of the late-Pleistocene to Holocene El Fraile cone.  Three major plinian eruptions, the most recent of which took place about 800 AD, have occurred from Popocatépetl since the mid Holocene, accompanied by pyroclastic flows and voluminous lahars that swept basins below the volcano.  Frequent historical eruptions, first recorded in Aztec codices, have occurred since precolumbian

The Department of Mechanical & Materials Engineering (engineering.unl.edu/mme) at the University of Nebraska-Lincoln (UNL) invites applications for a tenure-track faculty position at the Assistant Professor level. Successful candidates are expected to develop a world-renowned research program in the general areas of dynamics, vibrations, and acoustics (broadly construed) with an emphasis on mechanical metamaterials and metastructures. A research program that leverages AI/ML in a principled way, and/or involves autonomous (“self-driving”) labs for design, discovery, and characterization will be considered a significant strength. We seek innovative and inspirational scholars with a commitment to excellence in teaching, research, service, and engagement.

The Department of Mechanical & Materials Engineering (MME) consists of approximately 29 tenured/tenure-track faculty, more than 800 undergraduate students, and 120 graduate students. Recent investments in the College of Engineering include a new ~$80M research building and a new $120M teaching and learning building. The University

In-brief analysis

November 7, 2025

The United States produced 104 billion cubic feet per day (Bcf/d) of natural gas, 75% more than the world’s second-largest natural gas producer, Russia, in 2023, the most recent year for which we have comprehensive worldwide data on natural gas production. The United States has been the world’s largest producer of natural gas since 2009. More recently, U.S. natural gas production has increased further, averaging 106 Bcf/d for the first half of 2025 (1H2025). Three regions in the United States are among the top 10 natural gas-producing areas in the world when ranked independently against other natural gas-producing countries: The Appalachia region, in the northeastern United States, encompasses the Marcellus and Utica shale plays and ranked as the second-largest producer with 33 Bcf/d in 2023. More recently, production from the region
