Summer 2019 Research Opportunities

Specific ISRA opportunities will be canceled if enrollment minimums are not met. Should this occur, students will be given the chance to move to an opportunity with open seats or have their money refunded.

Biology

Molecular Neuroscience with Dr. Andrés Vidal-Gadea, Professor of Molecular Neuroethology

Projects in our lab look at the molecular and cellular basis of behavior using the model system C. elegans. Three ongoing projects will welcome students this summer: 1)  Duchenne muscular dystrophy  (DMD). This incurable disease affects 1 in 3,500 boys. Students will work to identify targets that can help slow down or halt the progression of this disease. 2)  Molecular mechanisms of magnetotransduction . Although it is known that many animals orient to the magnetic field of the earth, how this sensory feat is accomplished remains one of the holy grails of sensory neuroscience. Students will work to identify genes that are necessary for magnetic field detection and orientation. 3)  Biological effects of Mars’ magnetic field . Many organizations are working to place humans on Mars within the next couple of decades. Travel outside of earth’s magnetic field will expose humans to conditions never before encountered by any terrestrial life form. Students will assess the potentially detrimental effects of development under low magnetic field conditions. Developing animals will be raised under terrestrial or Martian field conditions, and effects on development and health will be evaluated. For each of these projects, students will learn about experimental design, hypothesis testing, and will conduct experiments involving microscopy, behavioral analysis, molecular techniques, data analysis, and presentation. (Minimum = 6 high school students and maximum = 16 high school students)   

worm

C. elegans  worm expresses a calcium indicator molecule in its muscles. When muscles contract and calcium is released, this molecule (called GCaMP) binds to it and emits light.

Chemistry
Chemistry of Gold Nanoparticles with Dr. Jeremy Driskell, Associate Professor of Analytical Chemistry

Gold nanoparticles have the potential to positively impact many aspects of modern medicine. These medical applications require a detailed understanding of how biological molecules, such as proteins, interact with gold nanoparticles. Students will be introduced to the unique properties and many uses of gold nanoparticles. With guidance, each participant will synthesize and characterize gold nanoparticles using state-of-the-art instruments. Each participant will then be assigned a different protein and conduct experiments to measure its adsorption onto the gold nanoparticles. Students will then search for information on the protein, such as molecular weight, charge, function, etc. As a team, students will share their findings and look for correlations between protein properties and adsorption behavior. (Minimum = 3 high school students and maximum = 8 high school students)

Biochemistry with Dr. Marjorie A. Jones, Professor of Biochemistry

Students will learn to grow Leishmania tarentolae, a one-celled organism, which is a pathogen for reptiles but not humans, so it can safely be used as a model system. Students will learn how to grow cells using sterile technique and measure cell growth using several enzyme assays. Students will also help perform spectroscopy assays to measure how additions of various compounds affect the cells. The long-term goal of this research is to propose new pharmaceutical drugs to treat human Leishmania diseases, which infect more than 20–25 million people worldwide and for which there are few good treatments. (Minimum = 4 high school students and maximum = 14 high school students)

Protein Biochemistry with Dr. Chris Weitzel, Assistant Professor of Biochemistry

Proteins fulfill countless functions. For example, they catalyze the multitude of reactions that are carried out within our bodies, provide structural support to cells, and are critical components of our immune system. Simply put, proteins are polymers of small molecules called amino acids. In the first step of translation or protein synthesis, an amino acid is attached to its appropriate transfer RNA (tRNA). This so-called “charged” tRNA then delivers the amino acid to the ribosome for use in translation. Importantly, this reaction is catalyzed by the aminoacyl-tRNA synthetases (aaRSs) and is fundamental to the accurate decoding of the genetic code. Because the aaRSs are essential bridges, linking the worlds of nucleic acids and proteins, this family of up to twenty enzymes is found in virtually every biological organism. 

It is becoming increasingly clear that synthetases, through multiple mechanisms, are gaining function in addition to their classical functions in translation. One powerful mechanism clearly at play is the evolution of synthetase paralogs, or two proteins that evolved from a common ancestor gene. Over time, the genes for these two proteins can accumulate mutations leading to variations in amino acid sequence and potentially different, but often related functions. Remarkably, there are several examples within the third domain of life, the Archaea, where a second gene encoding a protein product with homology to leucyl-tRNA synthetase (LeuRS) has been maintained. The short-term goal of my research is to understand the functional significance of maintaining a second LeuRS-like protein within the Archaea. Specifically, we are investigating the cellular role of this second LeuRS (LeuRS-I) within Sulfolobus islandicus (S. islandicus), a member of this domain. 

Students will be introduced to the many techniques involved with generating a protein to be characterized in a laboratory setting. With guidance from current lab members, which include undergraduate and Master’s level biochemistry students, participants will clone the genes for proteins particularly interesting to the Weitzel lab. Students will also purify a protein, capitalizing on its physical characteristics (affinity for a resin, size, and charge), after overexpressing the target using non-pathogenic Escherichia coli (E. coli). Students will use polyacrylamide gel electrophoresis and Western blotting as a means to identify proteins of interest. Opportunities to identify protein interacting partners, grow an archaeal extremophile, and carry out protein localization studies within E. coli and S. islandicus cells using fluorescence microscopy will also be available. (Minimum = 3 high school students and maximum = 6 high school students)

Nanoscience and Materials Chemistry with Dr. Jun-Hyun Kim, Associate Professor of  Nanoscience and Materials Chemistry  
Nano-scale metal particles are highly attractive optical materials because of their large surface areas, tunable structural changes, and easy recyclability. The optical property of metal nanoparticles originates from the surface plasmon resonance (the collective oscillation of conducting electrons on a metal surface). Upon exposure to light, these nanoparticles can transition to an excited state and the resulting electrons can relax back into their ground state, releasing energy in the form of heat. This heating event allows for a temperature increase on the surface of the metal nanoparticles and/or a reaction medium that can be applied to photothermally-enhanced catalytic reactions, signal enhancements, and triggering components for delivery systems. Our ultimate research goal is designing nano-scale materials that respond to external stimuli (e.g., pH, temperature, and light).   (Minimum = 2 high school students and maximum = 8 high school students)

Information Technology

MIT App Inventor with Elahe Javadi & Rosangela Follmann, School of Information Technology
In this project, students will develop an Internet of Things (IoT) mobile app on MIT App Inventor (appinventor.mit.edu/) to communicate with an Arduino device. We start with a basic app that turns on/off a light using a cell phone , then monitor our heartbeats on the app, and can advance the app depending on the interest of the participants.  Participants are encouraged but not required to carry an Android phone with them. (Minimum = 2 high school students and maximum = 6 high school students)
