Population & Community Ecology
Cascade Sorte, University of California-Irvine
Students in a Population and Community Ecology class participate in coastal marine research focused on understanding factors determining population sizes and community interactions, particularly in the context of species that appear to be shifting their ranges with climate change. Students participate in all aspects of the research from making observations and collecting data in the field to defining questions, stating hypothesis, designing and completing statistical analysis, and interpreting and presenting results. The outcomes are a research proposal, research paper, and poster presentation. All are intended to be at a level appropriate for use as a writing sample or presentation at undergraduate conferences. Results are incorporated into the ongoing research project led by the course instructor and graduate student teaching assistant.

An Arabidopsis Mutant Screen CURE for a Cell and Molecular Biology Laboratory Course
Jinjie Liu, Michigan State University
This CURE is designed from a crucial component of a chloroplast lipid signaling research project and has been implemented for a cell and molecular biology laboratory course at Michigan State University. The research laboratory generated an engineered plant line producing a lipid-derived plant hormone and mutagenized this line. The research question is "what transporters or receptors are involved in the hormone signaling transduction or perception processes?". Students form research hypotheses based on the research model, design experiments, perform experiments, collect and analyze data, make scientific arguments, and share their findings with the learning community. Specifically, the students culture the mutagenized plant population and select the desired mutant phenotypes, followed by genotyping the mutants and characterizing the mutants by basic biochemical approaches. Mathematics is also integrated into the course design. As the students studied the relevant genetic, molecular and biochemical concepts during this CURE, they use the core idea of information flow and data they generate in the lab to make claims about their mutant plants and support these claims with evidence and reasoning.

Biomass conversion into highly useful chemicals
SAPNA JAIN, Alabama State University
This is CURE based course that aims at bridging the gap between theoretical knowledge in chemistry and its practical applications at solving real-world problems. It gives students an opportunity to construct and synthesize their knowledge and skills by learning to apply theoretical knowledge to practice by the laboratory research. The purpose of this course is to acquaint students with the fundamental concepts of chemistry, synthetic methods and techniques. The emphasis will be on novel catalysts synthesis and evaluating their activity towards biomass conversion to liquid fuel and useful chemicals. Students will design synthesize, deduce identities of the biomass conversion products from chemical and spectral clues, and predict reaction products.

Characterizing the Aging Process Using Caenorhabditis elegans and Reverse Genetics
Joslyn Mills, Bridgewater State University
Using gene silencing (RNAi) in the nemotode C. elegans, students will identify genetic modifiers of proteins with roles in aging by reverse genetics. Specifically, students will analyze the effect of knocking down genes on the level of aging-related proteins tagged with fluorophores (GFP, RFP, etc.). Each group of students will use function-specific RNAi libraries (transcription factors, kinases, etc) already established in our lab. Furthermore, students will evaluate the effect of genetic modifiers on proteostasis and lifespan. In addition to becoming familiar with C. elegans work and appreciating the use of model organisms, the students will master microscopy, genetic crosses, gene silencing, and molecular and biochemical readout assays such as qPCR and immunoblotting.

Molecular Parasitology
Swati Agrawal, University of Mary Washington
In Spring 2021, we piloted a mini-CURE where student groups from University of Mary Washington and Georgia State University collaboratively completed research projects as part of a research-intensive course on Molecular Parasitology. The benefits of this approach were immediately obvious as students interacted across institutions, learned from each other's disciplinary expertise while informing their own research with data collected by their collaborators.

Community Flood Risk Assessment from Rising/Surging Seas Project
Kevin Kupietz, Elizabeth City State University
Globally 634 million people, 10% of the world's population, live in coastal areas less than 10 meters above sea level. According to 2010 census data, 123 million people, 39% of the United States population, live in coastal counties with an estimated increase to this number by 8% in the 2020 census. As natural disasters have been seen to increase in frequency and severity in the past five years coupled with expected sea rises from climate change it is important that anyone involved with the safety and resiliency planning of their organization/community have an understanding of how to scientifically assess risk from flooding in order to mitigate and recover from the effects. This project allows students the ability to develop skills to utilize computer modeling systems and to apply the data to real world communities in examining risk to structures as well as different groups in the community.

A Bioinformatic Look at Iron Uptake in Insects
Emily Ragan, Metropolitan State University of Denver
Students will perform BLAST searches, make phylogenetic trees, identify putative orthologs, and investigate secondary structure elements of 5' untranslated regions (UTRs). The sequences used will be related to iron uptake in insects.

The Art of Microbiology: an Agar Art Microbiology Lab CURE
Jeffrey Morris, University of Alabama at Birmingham
Students use agar art made with freshly isolated microbes as a source for developing their own novel research projects.

Synthesis of the Intermediate of a Catalytic Reaction: An NHC-Stabilized, First-Row Transition Metal Complex
Meng Zhou, Lawrence Technological University
The advanced synthesis laboratory course object allows students to study the synthesis, purification, and characterizations of a new diamagnetic organometallic complex of a first-row transition metal. The air-stable complex is stabilized by an N-heterocyclic carbene spectator ligand. It also bears an actor ligand and therefore, is potentially a reactive intermediate of a catalytic reaction. The synthesis of a reactive intermediate is the key to elucidate the mechanism of catalysis. The instructor chooses the first-row transition metal and the actor ligand based on his or her interests. The CURE starts from an NHC-ligated complex that does not bear this actor ligand but is otherwise similar. In our CURE, an anion ligand-replacement reaction was used to install the actor ligand, but an instructor may choose other approaches. The students will evaluate their results by standard spectroscopic analyses using UV-vis, FT-IR, and proton NMR (60 MHz or above) analysis.

The HICA project
In this CURE, inspired by the work of Hoffmann, et al., students prepare mutant Haemophilus influenzae carbonic anhydrase (HICA) proteins. Using PyMOL to visualize the three-dimensional structure of the HICA protein, students choose one or more surface amino acid residues to mutate to histidine residues in order to create a surface histidine cluster that will allow the mutant protein to bind to a nickel affinity column. Using site-directed mutagenesis, recombinant plasmids are constructed and are then used to transform an E. coli expression vector. The mutant HICA protein is overexpressed, cells are lysed, and students load the cell lysate onto Ni-NTA columns and determine the imidazole concentration required to elute the mutant protein. The construction of a library of mutant proteins will allow the development of a general method in which specific surface histidine residues of any protein can be mutated in order to facilitate affinity purification. The Haemophilus influenzae bacterium described herein is a respiratory pathogen that causes meningitis (in its encapsulated form) and mucosal infections such as otitis media, sinusitis and conjunctivitis (in its unencapsulated form). A recent study showed that the carbonic anhydrase enzyme is absolutely required for pathogenesis. Furthermore, expression of the HICA enzyme allows the pathogen to survive in host immune cells (Langereis, et al.). These observations make the study of HICA itself particularly attractive, in addition to the overall goal of contributing to a body of work that will allow the minimal histidine character required for nickel affinity to be ascertained.
