Article discusses how, after one year of operation, the Ingenuity rotorcraft and the Perseverance rover continue their exploration missions on Mars. Succeeding the technology demonstration phase, by proving its flight capabilities, Ingenuity transitioned to a new mission stage to explore modes of flight exploration for future scouting missions. The author's research intends to analyze, using numerical simulations, the aerodynamic conditions such as those experienced by Ingenuity during its flight missions.

Article reports on a trace-based assessment of approaches to learning used by middle school aged children who interacted with NASA Mars Mission science, technology, engineering and mathematics (STEM) games in Whyville, an online game environment with 8 million registered young learners. Differences in approach to learning were found illustrating the potential value of the methodology to curriculum and game-based learning designers as well as other creators of online STEM content for pre-college youth.

Article describes how development of solid lubricant materials that render reliable performance in ambient conditions, are amenable to industrial size and design complexities, and work on engineered surfaces is reported. This report presents the holistic exploration and correlation of structure-property-processing pertaining to the advancement of solid lubrication science.

This report discusses research on cooperation of autonomous NXT robots using Bluetooth wireless technology. The research project consisted of using Bluetooth technology to coordinate movements between two agents. This research is part of Research Experiences for Teachers (RET) in Sensor Education, a National Science Foundation (NSF) funded grant project.

This article proposes a toe line tracking (TLT) method for the automated measurement of dune migration rate and direction using multi-temporal digital elevation models (DEM) derived from light detection and ranging (LiDAR) data to overcome a major limitation of the existing method of pairs of source and target points (PSTP).

Article describes how Li-CO2 batteries with a theoretical energy density of 1,876 Wh kg−1 are attractive as a promising energy storage strategy and as an effective way to reduce greenhouse gas emissions by CO2 reduction and the formation of discharge product Li2CO3 and carbon. This article provides critical perspectives on the development of Li-CO2 batteries as well as a description of current issues and challenges associated with cathode catalysts, electrolyte, and anode for Li-CO2 batteries.

Article is an introduction to Artnodes issue No. 26, “AI, Arts & Design: Questioning Learning Machines" which addresses the question: Does generative and machine creativity in the arts and design represent an evolution of “artistic intelligence,” or is it a metamorphosis of creative practice yielding fundamentally distinct forms and modes of authorship?

This column reviews the book "Private Space Travel" for inclusion in school libraries. This review includes recommendations for teachers, content subjects, and a recommended grade level.

Presentation on the University of North Texas Libraries’ implementation of Faceted Application of Subject Terminology (FAST) headings in their catalog. It was presented at the American Library Association's (ALA) Core Interest Group Week event which was held virtually on July 26-30, 2021.

This article discusses the expansion of Maillezais Abbey and the creation of its hydraulic infrastructure.

This report describes the results of test excavations at 23 prehistoric and 16 historic sites on the periphery of Lewisville Lake, Denton County, Texas. The purpose of this report is to summarize the character and significance of the archaeological sites that were test excavated and recommendations for mitigation at those sites determined eligible for the National Register.

This book discusses the liberation of humans, animals and nature from both a biological and philosophical approach. The authors include information about biological and cultural evolution, as well as the implications of the organic or organismic ecological model. The index begins on page 345.
