Proteins perform a lot of different jobs within our cells. As proteins either age or mutate, they can begin to cause problems for the cells. The ubiquitin system, (present only in eukaryotic organisms - animals and plants), works to tag proteins that go bad. Proteins tagged by the ubiquitin system send a signal to proteasomes which then shred the bad protein, hence the expression “kiss of death.” Normally, a cell infected by a pathogen, (bacterium or virus), will undergo a process known as xenophagy, where an infected cell will kill itself to avoid becoming infectious to other cells around it. At the same time, the process of xenophagy kills the pathogens causing the infection. Even though pathogens don’t have a ubiquitin system, they have adapted their ability to survive by producing proteins that hijack the ubiquitin system of eukaryotic cells. Sebastian Kenny, PhD candidate the Department of Chemistry at Purdue University, explains the research he is doing to learn more about how pathogens are able to hijack the ubiquitin system.
Are there habitable planets outside of our solar system? Dr. Ravi Kopparapu, Planetary Scientist at NASA Goddard, explains that almost every star in our galaxy has a planet around it. This means there may be 100 billion planets in our Milky Way galaxy! Most of these planets range between the sizes of Earth and Neptune. Data available to exoplanet scientists is limited to what can be collected through remote observations with telescopes. Therefore, scientists tend to focus on terrestrial planets (similar to Earth), with suitable atmospheres (nitrogen and oxygen), that are able to maintain liquid water on the planet’s surface. A biological presence could interact and change the gas composition of the atmosphere, which could then be detected by remote telescopes and lead to potential discoveries of life.
What is medicinal chemistry? Delmis Hernandez, PhD candidate (focusing in organic chemistry) in the Department of Chemistry at Purdue University, describes the process of studying the skeletal structure of compounds in an effort to develop new medicines to fight cancer. Medicinal chemists identify the parts of a compound that are most effective as a medicine, but watch out for PAINS! These compounds can give false positive results that seem promising as a cancer drug when really the compounds might be toxic to both cancerous and healthy cells.
What might clouds on other planets, even planets outside our own solar system, look like? Alexandria Johnson, Assistant Professor of Practice and Research in the Department of Earth, Atmospheric and Planetary Sciences at Purdue University discusses the process of analyzing a few pixels of light, detected by telescopes, in order to study cloud formation on exoplanets. With a focus on sub-Neptune planets that could reach temperatures near 500K in their upper atmosphere, scientists believe there are clouds formed both from potassium chloride and zinc sulfide. On planets described as Hot Jupiters, which are thousands of degrees Kelvin in their upper atmospheres, there could be titanium oxide clouds and it may even rain rubies!
Brian Bates, owner of Bear Creek Organic Farm, suggests thinking about organic farming in terms of an overall broad system that includes biodiversity, soil health, and water quality. Over the last five years, organic food has accounted for the fastest growing segment in the food industry. The biggest challenge in American organic agriculture? We don’t grow enough organic food in America to satisfy the demand.

Dr. Monika Bleszynski, Research Scientist and Adjunct Professor at the University of Denver, discusses some of the harmful impacts of road salt along with potential alternatives. There are many negative impacts of the bioaccumulation of salt in environments near roadways, including damage to plant life, physiological drought, and the buildup of salt in our water reservoirs. By studying organisms with evolutionary adaptations to produce their own antifreeze proteins, Bleszynski has worked toward the development of safer alternatives to road salt with less harmful environmental consequences.

Ali has always been interested in space and did a variety of undergrad and grad projects. In this interview we discuss ice on Mars, what defines a planet, what types of planets are there, and the Earth’s tilt.
The flu and COVID-19 are both spread via respiratory droplets. While the science behind hand washing, mask wearing, and social distancing is very effective at preventing both flu and COVID-19, these precautions must be consistent. It only takes one time of forgetting a mask or not washing hands to become exposed to a virus. At this point, we haven’t stopped cases of COVID-19. Therefore we should still expect to see cases of the flu (beginning this October).

Hall explains that researching science questions generally leads to more questions. She shares that students need to reach out to others in order to discover more about careers they might be interested in exploring. She also tells us to explore other subjects in college to see what you might fall in love with. We discussed “Blue Holes” and Hall explains what they are and how they formed. Hall also explains what is involved with scientific diving and the process of becoming a technically certified underwater cave diver.
Don Robison seed administrator for the Office of Indiana State Chemist discusses seeds from China. The U.S. and other countries are getting unknown seed packets that vary in types. These seeds can be very dangerous to the U.S. agriculture and economy if planted. Don tells us that throwing them away is the same as planting them. He explains the 3 possible issues with these seeds. Don, tells Indiana residents to send the seed packets to the USDA APHIS (https://www.aphis.usda.gov/aphis/newsroom/stakeholder-info/sa_by_date/sa-2020/sa-07/seeds-china).
Don discusses the impacts of various noxious weeds and invasive species. Indiana is in the top five states in corn, soybeans, popcorn, field-grown tomatoes, duck production, egg production, and chicken production. He discusses what it takes to become a certified seed analyst and the roles that a seed analyst might have. Discussions in the differences in hemp and marijuana, the history of hemp in the U.S., the uses and regulations of hemp.
Mohit Verma is an Assistant Professor of Agricultural and Biological Engineering at Purdue University. Verma’s group has been busy working on developing a better test for COVID-19 with the goals of both simplifying the current test and providing faster results to patients. Traditionally, when patients are tested for COVID-19, they provide a deep nasal swab sample which is then analyzed for the presence of the virus. Verma’s group is hoping to develop a simpler testing procedure for patients that would instead analyze a sample of their saliva. Verma anticipates the new test could be completed from either the doctor’s office or eventually from the patient’s home. Over the past several years, Verma’s group had been developing a procedure for a similar test used with animals to detect bacterial infections. Verma explains the difference between both DNA and RNA, and the processes of transcription and translation. He then discusses the process his group is using to distinguish themselves from other COVID-19 tests that have been developed.
Dan Dawson is an Assistant Professor of Atmospheric Science in the Department of Earth, Atmospheric, and Planetary Sciences at Purdue University. Dawson researches the dynamics of severe thunderstorms and tornadoes. He analyzes output from different computer simulations to help better understand different aspects of both storm and tornado behavior. He also uses observational data collected in the field and has participated in a number of field programs to chase severe thunderstorms and tornadoes with instruments for collecting data from these storms. Two of the larger, multi-institutional field programs in which Dawson has participated include the Verification of the Origins of Rotation in Tornadoes Experiment (VORTEX2) and VORTEX Southeast (VORTEX-SE) programs. Dawson speaks about the three-dimensional structures of these storms that produce tornadoes and stresses that scientists need data both within and surrounding these storms, specifically wind flow patterns that surround severe thunderstorms, to best understand severe thunderstorms and tornadoes. The best instruments that scientists can use for obtaining high resolution data over the entire storm system is a Doppler radar. Doppler radar can either be in a fixed site like the XTRRA radar at Purdue. In this case, scientists have to wait for the storms to come to them. Mobile radar is another option in which Doppler radar instruments are installed on trucks that drive near the storms to collect data. Multiple trucks carrying multiple radars, and travelling at different angles to a storm, can synchronize their scans in order to provide scientists with full two-dimensional and three-dimensional views of the winds associated with a storm. Dawson’s particular niche has been the use of in situ precipitation stations designed to collect data from inside a storm. These probes are unique because they include a disdrometer which is a device used to measure the raindrop sizes in a severe thunderstorm. Dawson is interested in understanding raindrop size distribution because it can potentially be used to predict whether a tornado might develop within a severe thunderstorm. Dawson also explains the science behind weather fronts (synoptic or national scale), which he defines as boundaries between air masses with different characteristics. He further explains the difference between synoptic fronts and gust fronts which occur on a more local scale. If you are a student who would like to study storms or meteorology, Dawson recommends setting yourself up for success by taking as many math, physics and computer programming classes as possible.

Dan Cziczo, Professor of Atmospheric Science and head of the Department of Earth, Atmospheric, and Planetary Sciences at Purdue University. His group specializes in the study of aerosol particles in the atmosphere. Aerosol particles act as the seeds on which water, clouds, and ice crystals form within the atmosphere. The presence of these particles in the atmosphere scatter sunlight and cause hazy atmospheric conditions. Aerosols also influence the outgoing radiation from Earth to space, thereby making them a complex player in the energy balance of the Earth. One of the instruments used by Cziczo is a single particle mass spectrometer. His group has deployed this instrument on various NASA research aircraft and several years ago they were able to collect data from a base in Florida that was scheduled to fly through a Saharan dust storm. From this mission, Cziczo’s group was able to collect and analyze the chemical fingerprints of dust particles within that storm. Cziczo explains that Saharan dust storms are very common and have happened frequently for thousands of years during the summer. They are part of the trade winds and occur when material gets picked up off the arid regions of the Sahara and moves from east to west, where it ends up over either the Caribbean or Amazon. Occasionally, these storms will make their way over the continental United States. The most recent dust storm (Summer 2020) was a larger than normal storm and one that Cziczo classifies as a 50 year event. Small bits of this recent storm made it as far north as Minnesota and Canada. Cziczo mentions that aerosol particles can circle the globe several times before finally settling and he provides links (below) for listeners to be able to look up satellite imagery of these particles. While air quality (hazy conditions, pollution, pathogen transport) can be negatively impacted by the particles transported during dust storm events, they can also have a positive impact such as providing fertilization for the Caribbean islands, coral reefs, and even the Amazon rainforest. Cziczo mentions that ultimately, these dust storms
are an important part of our global system.

Buster Dunsmore is an Associate Professor of Computer Science who both researches and teaches software engineering at Purdue University. While computer programming can be accomplished by one person, software engineering requires a team of people. Software engineering is a current need for industries. There is not as much of a demand on individual programmers because software engineering teams can create a software package in a much shorter time, 2-3 months versus 1 year if only one person tried to create the same software package. Dunsmore relates the teamwork aspect of software engineering to putting together a big puzzle. Some of the best skills a person can bring into this field of study are good problem solving and communication skills. Dunsmore mentions a collaborative platform, GitHub (https://github.com/ ), which is a software repository used by many freshmen at Purdue that allows students to access and test each other's software. He also tells us not to worry if you are unable to take a coding class in high school. Not only does Purdue not require incoming freshmen to have taken a programming class in high school, but Purdue offers Introduction to Coding classes for students with no experience. Dunsmore was inspired to become a professor/teacher based on his own experiences as a student. When the opportunity came up, he volunteered to teach a freshman level course. He made a vow to himself that if he was ever in a position to teach a freshmen level computer science course, he would make improvements so future students could have a better experience than him.
Dr. Dunsmore's interest areas include software engineering, software architecture, agile methods, software metrics, Java, C++, C, JavaScript, cgi software, object-oriented design and programming, and information Systems. He has been a recipient of the awards Outstanding Teacher in the College of Science and Charles B. Murphy Outstanding Undergraduate
Teacher Award for Purdue University. He was chosen as a Founding Fellow of the Purdue Teaching Academy. Dr. Dunsmore has extensive legal and industrial consulting experience. He has written several technical articles and is coauthor of two books.
Herman Sintim, Drug Discovery Professor of Chemistry in the Department of Chemistry at Purdue University, has worked to develop a potential drug compound for treating an aggressive form of leukemia known as acute myeloid leukemia (AML). Leukemia is one of several different types of blood cancers. While there are a number of different drugs approved by the Food and Drug Administration (FDA) currently on the market for treating leukemia, patients treated with these drugs often experience a relapse with cancer. Chemists have the ability to study proteins that “go rogue,” or initiate cancer within a cell, and develop molecules (drugs) that are able to bind to such proteins and stop the cancer process. Sintim’s potential drug has tested very well with an animal model, and the next step is to answer the question: “Will it work in humans?” KinaRx LLC, a startup company co-Founded by Sintim, was recently awarded a grant from the National Cancer Institute that will help answer this question. Sintim explains that when a potential drug makes it to “clinical trials,” this is the first time the drug is administered to patients and evaluated to see whether it works. A small human population is used in Phase 1 of clinical trials. If the drug produces results indicating that it is working, the use of that drug is expanded to larger groups of patients in Phases 2 and 3. Finally, statisticians look at the results from these phases to see whether the data that has been collected indicates that the drug actually works. All of this takes place before the FDA provides approval for the drug to be administered to a larger human population and can take up to 15 years or more. Sintim follows with a great explanation of how timelines for moving both drugs and vaccines to clinical trials can become drastically shorter depending on the interest level related to development. With one group working on developing one drug or vaccine, the timeline is significantly longer than if many groups are focusing their efforts on the development of that same drug or vaccine. Sintim advises students to always follow their passions. By pursuing something that you find interesting, you will likely put more energy into your pursuits and find that you will excel.
Gouri Prabhakar is an Assistant Professor of Practice in the Department of Earth, Atmospheric, and Planetary Sciences at Purdue University. While the majority of her time is spent teaching both graduate and undergraduate students, she also researches both physical and chemical processes of the atmosphere that lead to change in the concentrations of various air pollutants. Prabhakar's research involves a combination of both data analysis and experimental work. She has participated in many field campaigns where she has collected samples of air, using instruments on aircraft, and analyzed them for pollutants. One of the goals of Prabhakar’s research is to better understand the chemical pathways that pollutants undergo in the atmosphere. By understanding the processes that various pollutants depend on, scientists can better understand and predict what the concentrations of pollutants will be in the future. One application of this research is to study the influence of pollutants on both the physical and chemical properties of clouds. When pollutants are added to the atmosphere, the surface area from which clouds can form increases because there are many more particles present. An increase in surface area leads to the development of many smaller droplets of water which creates a brighter cloud. The types of pollutants can also lead to the development of acid rain from the clouds. Prabhakar has been involved with several campaigns where data was collected from the eastern Pacific Ocean. The coast of central California was chosen as a setting for these campaigns because of the busy ports in this location. Prabhakar explains that the persistent deck of clouds located in this region, known as stratocumulus clouds, provide the perfect meteorological and anthropogenic setting where scientists can study the influence of the emissions from ships on clouds. The stratocumulus clouds combined with the stable boundary air below them creates an ideal, natural lab setting. Prabhakar encourages interested students to email professors doing research in an area of science that they find interesting. She suggests that many times students may find there are ways they can get involved either with looking at data or with various opportunities for summer projects. It is also important for high school students to develop a solid foundation in science and mathematics to help prepare them for a career in science.
Patrick Taylor is a climate scientist at NASA Langley. He discusses the interactions of Earth’s systems (atmosphere, ocean, land, humans, etc.) in impacting climate. Patrick’s research focuses on the impact of clouds and how clouds influence the energy balance of our planet. We discuss how the Earth emits energy upward, which escapes at the top of the atmosphere. This is the primary way that the Earth is cooled. Clouds impact how energy flows around the planet. Clouds both reflect energy from sunlight and insulate energy being emitted from the Earth. Over the last 40 years, NASA has observed a tremendous amount of decline in arctic sea ice. This has been brought about by increased CO2 emissions and have led to warming temperatures in the arctic (temperatures in the arctic have warmed more than twice as fast as the rest of the globe). In the arctic, with more sea ice melting, it was thought that more of the ocean would be exposed. Scientists hypothesized that with more exposed ocean, more clouds should form due to an increase in atmospheric water vapor. With more clouds, more sunlight would be reflected back to space. Therefore, it was believed that an increase in clouds would slow down the rate of arctic sea ice loss. However, data from both CloudSat and CALIPSO indicate that this hypothesis is incorrect. Patrick explains that due to the interconnectedness of our planet, atmospheric circulation (wind) moves carbon dioxide emissions from high populated areas to the arctic which then impacts the rate that sea ice melts.
Briony Horgan, Professor of Planetary Science at Purdue University, joins us to discuss the Mars 2020 Perseverance Rover Mission. Perseverance will launch in July 2020 (link below) and is scheduled to land on Mars at the Jezero crater in February 2021. How does NASA decide where to send the next Rover? Horgan was part of a team of scientists that evaluated Jezero crater as one of the candidate landing sites. She used satellite data to help think about the science that Perseverance could conduct at Jezero crater. Horgan explains that some of the best science you will see occurs as candidate landing sites are evaluated by scientists. Every participating scientist is invested in defending their landing site and many have very strong opinions. Perseverance follows Spirit and Opportunity, which were previous rovers searching for evidence of water on ancient Mars. The Mars Science Laboratory Curiosity Rover Mission followed up with the findings from Spirit and Opportunity by analyzing the chemistry of rocks at those ancient watery environments to determine whether that water could have supported life. Curiosity found evidence of a long-lived, habitable lake environment at Gale crater. Now that we know Mars had a habitable body of water, the Perseverance Rover Mission will be searching for signs of ancient microbial life on Mars. Jezero crater was selected because it seems to be the best example for evidence of an ancient crater lake on Mars. Horgan explains the complicated process, (Mars Sample Return), of collecting samples retrieved by the Perseverance rover and sending those samples back to Earth. Another point that Horgan makes is that NASA is concerned with planetary protection. The idea of planetary protection involves the consideration that we should avoid returning samples from another planet that could be potentially harmful to Earth. Also, contaminating other planets with Earth life should be avoided in order to reduce complications related to the understanding of the evolution of extraterrestrial life. One of the consequences of planetary protection is that NASA will not send missions to places where there may be even a slight chance that life may be living today. NASA also will not send anything nuclear powered to places where subsurface ice exists. In the event of a crash, there is concern that a nuclear powered spacecraft could melt subsurface ice and create a refuge for Earth life that would contaminate the extraterrestrial environment. A future mission idea might involve sending a rover to the Mars polar caps to collect ice core samples so that climate change on Mars can be better studied. This would help us refine our climate and atmospheric models for Earth systems.

Barbara Cohen is a Planetary Scientist at NASA Goddard Space Flight Center. Her interest lies in impact events across the Solar System. Barbara’s work includes laboratory geochronology (time and earth) to determine when rocks formed. Because she is not able to travel to places like the Moon and Mars, Barbara instead relies on robots that can travel to these places and perform investigations. She has participated in NASA missions that include Mars Exploration Rover, Spirit, Opportunity, Curiosity, and the current Perseverance mission. Rovers from each of these missions have collected samples and returned them to scientists back on Earth. Barbara is hopeful that the United States will eventually send a robot to the Moon to collect samples. Plans for travel to the Moon include a possible mission (hopefully in 2021) called Lunar Flashlight, where a very small satellite will shine a laser on some of the Moon’s darkest craters in an attempt to look for ice hidden at the Moon’s South Pole. Lunar Flashlight will also serve to collect information related to the record of bombardment in our Solar System. All of the comets and asteroids that have been hitting the Earth and the Moon leave traces of themselves behind that can be used as a time capsule. Barbara is also working on sending a mass spectrometer to the moon that will travel on a commercial lunar lander (hopefully in 2021). Barbara explains how mass spectrometry works. The mass spectrometer will look at molecules in the lunar exosphere and provide data that Barbara can use to do geochronology on the Moon. Barbara is also interested in improving imagery to allow people on Earth a better virtual reality experience for what it’s like on the surfaces of both the Moon and Mars.
David Thompson is a professor in the Purdue University Department of Chemistry with a courtesy appointment in the Department of Biomedical Engineering. His group uses organic chemistry, which makes and breaks bonds to create new compounds. They work to create compounds both for new pharmaceuticals and to help with better drug delivery. Thompson explains that the photos you see online of the COVID-19 virus are actually reconstructions of images taken using an electron microscope. The electron microscope helps us get precise enough images to do a better job of designing drugs in order to improve human health. The goal of imaging a virus, or any other submicroscopic object, is to create an atomically precise picture of that object. For example, knowing the exact shape of a virus allows us to better select a compound that can inhibit that virus from infecting a cell. Pharmaceutical companies specializing in drug discovery will have libraries of up to 4 million different compounds, with information related to the shape and size of each of them. Thompson explains compounds and enzymes. He also explains how students work through the design, build, test, and analyze process for testing hypotheses and answering research questions. It is important to work towards developing good questions that will give clear answers during the analysis of the research results. When designing experiments, it is also important to create both positive and negative controls. Both the positive and negative controls should be completed before the real test in order to avoid getting a false positive.
David Sanders, Associate Professor in the Department of Biological Sciences at Purdue University, works on introducing genes, or nucleic acids (DNA and RNA), into cells with the hope of producing a therapeutic benefit to treat disease. Using the virus as a shell, David can manipulate different properties of a virus. One modification involves changing the proteins on the outside of the virus. The modified virus can then be used as a delivery vehicle for introducing genes into particular targeted cells. Different viruses target different types of cells: some viruses want to go into white blood cells, liver cells, brain cells, or cells in the respiratory tract. Gene therapies are probably best known for their use in treating genetic diseases such as sickle cell anemia and cystic fibrosis. However, gene therapy can also be used to treat cancer and, of current interest, to generate an immune response against coronaviruses. Viruses have perfected the technique of bringing nucleic acids into cells. Instead of having viruses transmit their own nucleic acids, David modifies them to transfer preferred genes. David refers to these as “mix and match viruses” because they take certain traits from different viruses to make an ideal combination for delivering gene therapy. One safety modification used in his lab is to fix the viruses so that they can’t reproduce themselves. David’s group has worked on a virus that acts like a retrovirus on the inside. Retroviruses go backward from RNA to DNA, meaning the gene a retrovirus delivers becomes permanently incorporated into the target cell. The protein on the outside of the virus that David’s group studies was replaced with a protein found on the outside of the Ebola virus. This allowed his group to target cells found in the lung airway epithelium where it would be ideal to target gene delivery in order to cure cystic fibrosis.
Another interest of David’s involves the ethics surrounding the process of scientific publication and the peer review process. David comments on safeguards that can be used to help prevent bias within research science. It’s important for the scientists who first come up with an idea to be properly credited for their work.

Angeline Lyon, Assistant Professor of Biochemistry in the Departments of Chemistry and Biological Sciences at Purdue University, researches enzymes needed to maintain a healthy cardiovascular system. Specifically, her group studies Phospholipase C (PLC) enzymes which help trigger the release of calcium from inside the cell. Calcium oscillations drive body functions like muscle contractions, nerve impulses, and control how efficiently the heart beats. If calcium levels aren’t maintained, it can result in conditions such as irregular heartbeat, cardiac hypertrophy (abnormal enlargement, or thickening, of the heart muscle), or in severe cases it can lead to heart failure. Angeline’s lab uses multiple techniques to determine how proteins behave. X-ray crystallography is one method which helps her obtain “atomic snapshots” of proteins. This allows her to see where the amino acids are located within the proteins and consequently determine how those proteins work. Angeline also states that her lab is beginning to use electron microscopy which involves labeling proteins from a cell with a green fluorescent protein in order to track the movements of the labeled proteins within the cell. Additionally, her lab uses polymerase chain reactions (PCR) to help with protein mutations. Angeline offers advice to both undergraduate and high school students looking to get connected with opportunities to work in research labs.
Purdue University Chemical Engineering graduate, Caroline Kostak, worked as a flight controller with United Space Alliance out of college. After that she worked to help make buildings green in Houston, TX. She was inspired from the movie Inconvenient Truth to work with green buildings. For Earth Day 2020, Caroline suggests that students can do an energy audit of their home and she encourages kids to get their parents involved. Caroline now works as a Spacesuit Systems Engineer, with a team, designing a new spacesuit that astronauts will wear on the next Moon mission. There are many variables to consider when working to design a new spacesuit. Caroline discusses some of these challenges that she, along with a team of approximately 250 people, is working on. Caroline explains that a person's ability to work with others is the key to success. She further discusses the materials that go into the design of the new Spacesuit, issues with Moondust, possible NASA spinoffs, various suits that the astronauts need, and the space station Lunar Gateway.
Jeff Lucas, a professor in the Department of Biological Sciences, researches and teaches animal communication. Animal communication is the study of the interaction of living organisms. An important aspect of understanding communication is understanding how sound travels in different environments. This leads us to the complexity of vocal cords and social systems. The more dimensions of a social system, the more complex the communication needs to be. Jeff tells us about the very complex vocal system of the Chickadee. They have 15-20 different ‘letters’ in their language which produces thousands of different Chickadee calls. Jeff further explains that the complexity of the vocal system is seasonal, mixed-species flocks, changes in hearing, differences in birds hearing systems, and seasonality.
Assistant Professor of Earth and Space Sciences at West Chester University, Christopher Roemmele, teaches Science Education Methods classes (Secondary, Middle Grades, and Elementary) and Introductory Geology. Christopher was a classroom teacher before becoming a university professor. He supervises student teachers, runs committees, prepares lessons, presents at conferences, and publishes his research. He encourages science teachers to not just provide vocabulary and have students write definitions but to reflect on how they are teaching science skills. He encourages teachers to think about “What’s Your Story” when writing your lesson plan. Think about the lesson as a story with a beginning, middle, and end. Think about where you want students to go by the end of the story. He says to not worry about time break down for each part of the lesson when creating the lesson plan. Christopher discusses using demos to help students make connections. He encourages us to think of the story as a “Bridge of understanding from the known to the unknown”.
Mike Reppert, Assistant Professor of Chemistry at Purdue University, researches biophysics and spectroscopy with a focus on photosynthesis to better understand green plants, algae and cyanobacteria. Reppert’s group is interested in how sunlight interacts with chlorophyll pigments in photosynthetic proteins. Visible light includes the wavelengths of sunlight that plants and cyanobacteria use to produce chemical energy. By knowing how natural photosynthetic systems work, Reppert is hoping to learn how to design new systems that can be used to produce biofuels more efficiently. Reppert’s group is involved with molecular biophysics where physical principles are studied to understand how molecules interact with one another. Through studying molecular interactions at the biophysical level, Reppert is hoping to show improvement in light-harvesting from the photosynthetic organisms studied by his group.

Jani Sparks, Stable Isotope Specialist at the Purdue University Stable Isotope Facility, discusses the process of analyzing samples for Professors at Purdue University. To begin, isotopes can be thought of as chemical tracers. Carbon-14 is not a stable isotope, which makes it useful for radiocarbon dating. However, the Stable Isotope Lab looks for differences between stable isotopes over time, such as the relationship between Carbon-12 and Carbon-13. A variety of isotopes exist and common light, stable isotopes are referred to as “CHONS” - carbon, hydrogen, oxygen, nitrogen, and sulfur. Stable isotopes of these elements are the most common to be analyzed in the Purdue University Stable Isotope Facility. An Isotope Ratio Mass Spectrometer is the instrument used by Dr. Sparks to analyze gas samples. Applications of the Stable Isotope Lab include looking at food webs and determining trophic levels of different species. By analyzing bones or hair using carbon and nitrogen stable isotopes, Dr. Sparks can tell whether or not someone is a vegetarian. Archaeologists can analyze bones to determine where animals may have migrated from using various stable isotopes. Additionally, national labs like the FDA make use of stable isotopes to determine whether substances such as honey, lemon juice, and maple syrup are pure or adulterated. Dr. Sparks advises high school students to check out stable isotope facilities, either at Purdue or other large Universities, and recommends that interested students seek out a Stable Isotope courses.

Michelle Thompson, Assistant Professor of Planetary Sciences, looks at the building blocks of life in samples and dust from asteroids, comets, and meteorites. She tells us some clues to knowing if a rock is or is not a meteorite. Did you know that you can volunteer to go to Antarctica to search for meteorites for research? Michelle discusses what asteroids are and where they come from, the ‘new moon’ that the Earth has “friended”, and her career path which led to researching Planetary Science. Her recommendations to students include seeking out research opportunities and to “make them tell you no”. Several weeks ago, Michelle became one of the first 20 people in the world to examine and analyze a sample that was brought back from an Apollo mission.
Grey is a hydrologist who uses machine learning (advanced artificial intelligence) to get a better sense of where water is currently located on the Earth’s surface, and where it will be located in the future. Hydrologists monitor water around the world, create models to replicate the data they collect, and then use those models to make predictions about future events such as where flooding will occur. Grey has camped “in the middle of nowhere in Australia” where he tested soil moisture for the SMAP Cal/Val program. Grey recommends high school students learn how to write computer code and manage a GitHub repository (social media for computer programmers). A great beginning computer code for students to try is Python, and there are several online courses to help students get started. Grey also encourages students to maintain a strong foundation in mathematics.

Chris Andronicos started his adventure into science at Los Alamos where he found his passion for geology. He studies the evolution of the solid earth, particularly the continental and oceanic crust, and underlying mantle lithosphere. He discusses the concepts of ‘melt’, the geology of both Oman and Greece, and what an outcrop is. Chris has been part of groups that have discovered new minerals including rare alloys of copper and aluminum that only form in meteorites. The tools of the trade for this field geologist are primarily a Brunton compass and a petrographic microscope. Chris can look at a rock through a microscope and tell all kinds of things about the rock. However, he can often tell you what a rock is just by touching it, (before even looking at it)! Chris and his wife are both first-generation college grads and their advice to students is to be persistent.
Lisa Welp researches both carbon and water cycles, and how plants respond to extra CO2 in the atmosphere. She addresses the important building blocks of life: CHONPS (carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur). Lisa addresses the ocean’s role as a carbon sink (Henry’s law), removing CO2 from the atmosphere. As part of her research, Lisa’s group utilizes lasers to analyze isotope ratios in atmospheric samples. She has also been able to estimate the total amount of photosynthesis that occurs on the planet. She further explains that scientists can not prove things, they only support or disprove concepts.
