Steve Rowland (Geoscience) recently published "Early Adaptation to Eolian Sand Dunes by Basal Amniotes is Documented in Two Pennsylvanian Grand Canyon Trackways" in PLOS One. The study confirmed the oldest vertebrate tracks in the Grand Canyon. The two sets of fossilized tracks are approximately 313 million years old and are lying in view on the park's Bright Angel Trail. The tracks are among the oldest tracks on Earth of shelled-egg-laying animals, such as reptiles, and the earliest evidence...

Simon Jowitt (Geoscience) was featured in an Ars Technica article on the rare earth elements, covering demand for these elements that are critical for modern technology, green energy, and defense. The article highlights recent UNLV geoscience research on the geology and potential recycling of the rare earth elements, and how developments in this area may be able to better enable us to meet demand for these vital commodities.

Jesse Barnes (Public Policy & Leadership) and Michael Nicholl (Geoscience) recently had their article "Mildly hydrophobic biobased mulch: A sustainable approach to controlling bare soil evaporation" published in Vadose Zone Journal. This article was adapted from Barnes's thesis project from his master's degree in UNLV's water resources management program. Barnes is currently a doctoral student in public affairs.

Min Li (Physics and Astronomy) will have a new study appear in the Monthly Notices of the Royal Astronomical Society — a major international astronomy journal. She and her collaborators, UNLV's Jason Steffen, Zhaohuan Zhu (both Physics and Astronomy), and Shichun Huang (Geoscience), as well as Misha Petaev at Harvard, combined simulations of a planet-forming disk with software that calculates the chemical compounds that form from an initial array of chemical elements. With this, Li , a...

Jason Steffen (Physics and Astronomy), Shichun Huang (Geoscience), and Zhaohuan Zhu (Physics and Astronomy) were awarded a $550,000 research grant from the National Science Foundation for "Modeling Dust Condensation in Protoplanetary Disks". This program will combine UNLV's expertise in geochemistry and in planet formation to calculate the composition planet-forming material both in the solar system and in planetary systems that orbit distant stars.

Simon Jowitt (Geoscience) and colleagues from Hefei University of Technology and Uppsala University recently published a paper on the use of magnetite compositions to determine the processes that formed major mineral deposits in eastern China. The paper, "In situ LA–ICP–MS Trace Element Analyses of Magnetite: Genetic Implications for the Zhonggu Orefield, Ningwu Volcanic Basin, Anhui Province, China," was published by Mineralium Deposita.

Arya Udry and Chris DeFelice (both Geoscience), along with Zoe Wilbur, '18 BS Geology; Rachel Rahib, '15 BS Geology and '18 MS Geoscience; and Logan Combs, '18 MS Geoscience, co-authored the manuscript "Reclassification of Four Aubrites as Enstatite Chondrite Impact Melts: Potential Geochemical Analogs for Mercury" in the Meteoritics and Planetary Science Journal. This study, in collaboration with NASA Johnson Space Center, Rutgers, and the University of New Mexico, focuses on the geochemistry...

Five College of Sciences faculty exhibited posters at the UNLV Best Teaching Practices Expo Jan. 29. Gabriel Judkins (Geosciences) and Rex Suba: "Embedding Accessibility in Course Development" Elana Paladino (Sciences): "Mentoring meetings increase student performance on 'high stakes' projects in STEM" Viktoria Savatorova (Mathematical Sciences): "Active Learning and Transparency in Teaching Gateway Mathematics Courses" Alison Sloat (Sciences): "Pre-tests Improve Students’ Critical Thinking"...

Arya Udry (Geoscience) co-authored the manuscript "Martian Magmatism from Plume Metasomatized Mantle," which was recently published in Nature Communications. This study shows that the two main types of Martian meteorites (shergottites and nakhlites) could have formed from the same volcanic processes that create volcanoes in Hawaii as demonstrated by the meteorite chemical data.

Arya Udry (Geoscience), was awarded two NASA program grants. One is a three-year, $330,540 NASA Solar System Working Program grant titled, "Petrogenesis of Poikilitic Shergottites and Implications for Martian Geochemical Reservoirs." This grant is to study a comprehensive suite of Martian meteorites called the poikilitic shergottites. These meteorites are exceptional because they record the evolution of the magma from the mantle to the surface of Mars. They also provide significant information...
