Characterizing the Aging Process Using Caenorhabditis elegans and Reverse Genetics
Joslyn Mills, Brown 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.

Resequencing of Commercial Microorganisms
Jessica Kaufman, Endicott College
Students choose a probiotic pill or product with labeling that indicates the species and strain of bacteria in the product. Products are chosen so that a high quality reference genome sequence is available on NCBI. After DNA isolation and library preparation, high-quality student samples are pooled for next-gen sequencing on an Illumina MiSeq. The following semester, students in the required bioinformatics course will analyze the FASTQ files from the NGS run with a simple variant call workflow on usegalaxy.org. Then, each student will use a R Shiny app developed for this CURE to convert the VCF output from Galaxy to a FASTA file for an assigned gene in the resequenced genome. Students will complete their research experience by submitting the FASTA file to the NCBI Nucleotide Database.

The Effect of Silver Nanoparticles on Plant Growth and Herbivory
Erin Rehrig, Fitchburg State University
In this CURE, students will conduct experiments to determine the effects of silver nanoparticles on plant growth and insect herbivory. Students will synthesize their own nanoparticles and treat Arabididopsis plants with them. After 5 weeks, insects (Pieris rapae, caterpillars) will be placed on plants and insect herbivory will be assessed across treatments. Insects will be weighted before and after feeding assays. Plant growth rates and insect herbivory measurements will be done using digital photography and image analysis using MathLab.

Spicing things up: Implementation of a CURE to investigate the antimicrobial properties of spices on six bacterial species
Heather Townsend, Community College of Rhode Island
I issue students six bacterial species for use. I have students start the semester understanding primary literature and how to find sources, plagiarism, and how to use citations. They must then pick a spice (one per group) using literature, meaning they have to research that a particular spice has been shown to have antimicrobial properties. Once selected they do a series of dilutions and finally test the dilutions on the six bacterial species. All groups must use the entire class data in their discussion along with the historical data from previous semesters. They end in designing a poster which they finally present at a poster presentation open to the college.

Lexical density and diversity in people using augmented communication
Kay Chen, SUNY College at Fredonia
For this assignment, students are to form small groups (3 persons) and experience the process of conducting a group-design study from the initial study design and preparation, data collection, data analysis, and result interpretation.

Squirrels in the City: Urbanization in a Changing World
Christopher Thawley, University of Rhode Island
Our planet is undergoing a variety of changes due to human activity, including the expansion of cities across landscapes. However, urban environments are not wastelands but functioning ecosystems where organisms encounter a variety new conditions and potential challenges. One way that animals can respond to living in cities is by changing their behaviors. In this course, we will conduct an original research project exploring whether squirrels that live in urban habitats have changed their behaviors in predictable ways.

Types of Probiotic strains and their concentrations
Luda Bard, Howard Community College
In this CURE, students are going to research what types of probiotics are found in the probiotics that are available in grocery stores for purchase. They will investigate the concentration of those probiotics depending on expiration date.

Biochemistry of Crithidia fasciculata
Amy Greene, Albright College
Students in my second-semester biochemistry lab will study the biochemistry of the flagellated parasite Crithidia fasciculata. Students in Paul Ulrich's CURE at Georgia State generate C. fasciculata cell lines overexpressing putatively mitochondrial proteins with GFP tags. The goal of my CURE is for students to design experiments study the biochemistry of these cell lines, giving us more information about the structure and function of mitochondrial proteins in this poorly-studied parasite.
