The D2D program is centered around an undergraduate-friendly protocol workflow that follows the design-build-test-learn engineering framework. This protocol has served as the scaffold for a successful undergraduate training program and has been further developed into courses that range from a 10-week freshman seminar to a year-long, upper-division molecular biology course. The overarching research goal of this CURE probes the current predictive limitations of protein-modeling software by functionally characterizing single amino acid mutants in a robust model system. The most interesting outcomes of this project are dependent on large datasets, and, as such, the project is optimal for multi-institutional collaborations.

Laser spectroscopy of atmospherically relevant molecules and clusters in helium nanodroplets
Paul Raston, James Madison University
Superfluid helium nanodroplets present an ideal medium for the study of chemical dynamics at the molecular level. Their low temperature, enormous heat conductivity, and weakly interacting nature allow for the investigation of various things, such as how molecular rotation is effected by a solvent, and how molecules interact with each other. These two topics will be addressed in the lab by (1) measuring the spectra of unexplored molecules in helium nanodroplets and determining their rotational constants; this data will then be used to test known models describing the interaction between the molecule and helium solvent, and (2) synthesizing and characterizing unexplored molecular clusters in an effort to better understand molecular solvation; students will solvate the "unexplored molecule" with an atmospherically relevant species (O2, N2, H2O), and investigate the resulting clusters with laser Stark spectroscopy.

Topography with Muons
Richard Lombardini, St. Marys University
Accuracy for 3D positioning is affected by surrounding media when using traditional techniques such as GPS. Other devices may need to be developed that produce readings unaltered by the conditions of the local environment (Tanaka 2020). The trajectory of highly energetic atmospheric muons experience very little change when traveling through different media, and the flux of particles is uniform and ubiquitous along surface of Earth. Using the TeachSpin muon detectors and theories of special relativity and quantum mechanics learned in class, students will determine the level of accuracy that they can achieve in the measurement of elevation at any location by directly measuring muon stopping rates.

Using CRISPR/Cas9 technology to investigate the molecular genetic basis of root traits in plants
Dong Wang, University of Massachusetts-Amherst
This CURE brings authentic research on plant molecular biology to undergraduate students in an advanced lab course. The experimental design investigates plant genes controlling root traits utilizing CRISPR/Cas9 technology in transgenic hairy roots. By cloning and delivering CRISPR/Cas9 constructs, students will acquire powerful skills in molecular biology such as Golden Gate cloning. By combining fast-growing hairy roots (a versatile system suitable for multiple plant species) with candidate root genes, students can advance genotyping to phenotyping in one semester. The outcome is a hands-on experience of the power to genome modification beneficial to the students' future career.
Investigating Neural Stem Cell Regulation in the Zebrafish Brain
Rolf Karlstrom, University of Massachusetts-Amherst
By now we have all heard about adult neural Stem Cells (nSCs) and the great promise they hold for treating neurological diseases, especially neurodegenerative diseases such as Parkinson's Disease or Alzheimer's Disease. We'll talk more about these cells in the course. In order to be useful in treating human disease, we must first learn what controls nSC division (proliferation), and what controls the types of neurons and glia that are produced (differentiation). Many labs around the world are working hard on these problems using a variety of lab animals; from worms to flies to fish to rodents to humans (using human induced Pluripotent Stem (iPS) cells). In this course we will take advantage of the experimentally accessible larval zebrafish to perform experiments designed to learn more about the regulation of nSCs and neurogenesis, the process of making new neurons and glial cells needed to make a functioning vertebrate brain.Why are new neurons (and glia, never forget glia) produced in the adult brain? One obvious answer is that this adult neurogenesis helps maintain the brain as it ages (e.g. replacing cells that die). While this may be true to some degree, especially for glial cells, we know that most cells in the brain simply aren't replaced when they die (a fact highlighted in neurodegenerative diseases) and it is not simple to replace functional neuronal connections. A relatively new idea is that new neurons and glia may be generated in parts of the brain as a normal part of the brains ability to function to guide behavior and respond to the environment. In this course students will learn about the regulation of stem cell proliferation and differentiation and we expore the idea that the generation of new neurons is part of normal brain function, helping zebrafish larvae to maintain internal physiology (homeostasis) in response to a changing environment. Students will become familiar with zebrafish embryonic and larval development, will design and implement experimental treatments of larvare, dissect larval brains, perform a chemical reaction to fluorescently mark proliferating cells, image larval brains using a fluorescent microscope, and count proliferating cells.
Random gene mutagenesis for gene identification linked to prodigiosin production in Serratia marcescens
Verena Carvalho, University of Massachusetts-Amherst
This lab course is designed to provide course-based undergraduate research experiences. You will learn how to prepare, execute, and interpret your own experiments. While all of you will conduct the same techniques in the course, each of you will create their own sets of mutant strains and study different features of your bacterium. We will study Serratia marcescens, an opportunistic, nosocomial pathogen, and is particularly linked to catheter-associated bacteremia, urinary tract infections, and wound infections. It is responsible for 1.4% of hospital-acquired infection cases in the United States. These bacteria are commonly found in the respiratory and urinary tracts of hospitalized adults, and in the gastrointestinal systems of children. Many strains of S. marcescens have a bright red colony color (a tripyrrole pigment called prodigiosin), while pigment production is often temperature-dependent. Prodigiosin is a secondary metabolite, and its expression is thought to be related to phosphate limitation. It was also identified as a natural bioactive substance with high potential for antibiotic and anti-cancer applications. It currently receives renewed attention for its wide range of potential applications, including activities as antimalarial, antifungal, immunosuppressant, and antibiotic agents. It is also prominently known for its capacity to trigger apoptosis of malignant cancer cells, and high activity against stationary phase Borrelia burgdorferi, the causative agent of Lyme disease, has been demonstrated. Given its diverse effects, the exact mechanisms are currently not elucidated, and may be highly complex, including phosphatase inhibition, copper mediated cleavage of double stranded DNA, or disrupting the pH gradient through transmembrane transport of H+ and Cl- ions. Clearly, prodigiosin is a highly promising drug candidate, and is currently in preclinical phase study for pancreatic cancer treatment. In this course, we will use the transposon Tn5 to generate random mutations in the chromosome of Serratia marcescens. The transposon will be provided by a plasmid hosted in a donor E. coli strain, and transferred into your test bacterium via conjugation. We will then first select for successfully transposed mutants by testing for antibiotic resistance, and screen for your mutants that are altered in their pigment production. To identify the gene where the mutation has happened, we will remove the chromosomal DNA from the mutant strains, perform restriction enzyme digest, and generate self-circulating DNA. These plasmids are transformed into an E. coli strain that can replicate the fragment of genomic DNA that contains the transposon, and we can sequence the insertion site with the transposon DNA as anchor. In summary, in this course you will gain hands-on experience with modern genetic and biotechnological techniques, you will gain insights into bioinformatics and into working with public databases, which are all essential skills in modern microbiological research.

The Most Luminous Galaxies in the Universe
Min Yun, University of Massachusetts-Amherst
My research group has found about 30 most luminous galaxies known in the early universe by analyzing a large data set produced by the NASA/ESA Planck cosmology probe. The goals of this research class is for the students to learn about these galaxies and their importance, how they are identified, and ultimately discovering many more such galaxies yet to be discovered from the parent candidate list.
