Session 2f Bees At The Table: Ecological And Cultural Connections Between African American And Native American Cuisines, Soleil Culley Apr 2021

Session 2f Bees At The Table: Ecological And Cultural Connections Between African American And Native American Cuisines, Soleil Culley

The Youth Environmental Alliance in Higher Education

What are the ecological and cultural connections between squash bees, African American, and Native American food cultures? Two subfamilies (Peponapis and Xenoglossa) were identified as bees of interest because their host plants (Cucurbita) could be connected to food cultures. Cucurbita was found to be a common host squash species found throughout North and South America. Searches in academic literature databases connected cultural and ecological knowledge to agricultural history of the Trans-Atlantic slave trade. Skilled slave labor and products were not the only trading goods; various plants were transplanted during the Trans-Atlantic slave trade.Throughout history squash became more integrated in food …

Session 1g Online Purchasing Environmental Impacts, Grace Turner Apr 2021

Session 1g Online Purchasing Environmental Impacts, Grace Turner

The Youth Environmental Alliance in Higher Education

Online purchasing has negative effects on the environment. Some effects can include ocean pollution with plastic and other wastes and then the additional waste that comes from shipping products. According to a research done in 2013 found that the traditional shopper tends to have alower CO2 footprint, at least when it’s compared to many different types of online shoppers. When it comes to online shopping people who order express delivery should be made aware of the impact they will make. Also, packaging should be made more efficient and include less plastics that would eventually end up in the ocean.

Session 2f The Benefits Of Nature On Human Health During The Covid-19 Pandemic, Erica Eason, Zoe Goldenberg, Emily Hayden, Kennedy Little, Madeline Moss, John Schalk

The Youth Environmental Alliance in Higher Education

Throughout the COVID-19 pandemic and resulting lockdown, human experiences in nature became increasingly prevalent. Studies have concluded that these experiences and encounters with nature have had a significant benefit on human health both physically and psychologically. One study conducted on the use of greenspace during lockdown found “...consistent positive associations between frequency of greenspace use and the five measures of mental health outcomes” (Soga et al., 2020). We aim to analyze the findings of other research studies in an attempt to fully describe the total benefits of nature within the context of current pandemic life, including Covid-related compliance.

Session 2c Increased Sanitation Due To Covid-19 Poses A Dilemma For Waste Management, Sydney Castellanos Apr 2021

Session 2c Increased Sanitation Due To Covid-19 Poses A Dilemma For Waste Management, Sydney Castellanos

The Youth Environmental Alliance in Higher Education

Among the many changes that have come with COVID-19 has been the shockingly increased production of personal protective equipment. The increased disposal of such products calls for the development of novel management plans to prevent public health from being to the detriment of environmental health. Medical waste was found to have a 350% increase during the pandemic (Sarkodie & Owusu, 2020). Management of this issue will need to consider the sustainable alternatives to some of the readily available products currently in production and novel ways of recycling or repurposing these waste materials.

Session 2f Daily Nature Activities For School Children In The Covid-19 Era, Ryann Hartung Apr 2021

Session 2f Daily Nature Activities For School Children In The Covid-19 Era, Ryann Hartung

The Youth Environmental Alliance in Higher Education

Kindergarten through grade twelve programs need to have more nature based recreation programs in their daily lesson plans. This would encourage kids to take control of their own relationship with nature. It could also encourage kids to choose different career paths that they would like to do. I think using recess time to goon nature hikes or doing nature therapy techniques would be more beneficial than doing sport games or playground activities. This would also be more sanitary and adhere to COVID-19 recommended guidelines. They could be masked, distanced and have a more educational experience while still having fun.

Session 2f Edible Forests: Addressing Urban Heat Islands Through Food Security, Amanda D'Agostino Apr 2021

Session 2f Edible Forests: Addressing Urban Heat Islands Through Food Security, Amanda D'Agostino

The Youth Environmental Alliance in Higher Education

Urban Heat Islands are built environments that retain heat and lack green spaces which absorb heat, causing cooler temperatures. According to Jenerette et al. (2011), there is a correlation between lower income and lack of greenspaces in the neighborhood, segregating those with lower financial power. An example of this is the 1995 heatwave in Chicago that killed 700 people, often elderly or lower income residents. Developing and maintaining edible forests will help cool the neighborhood and help feed the community with locally grown nutritious food in areas of food insecurity. Partnerships with local farmers, volunteers, community members, and municipalities should …

Strontium-90 Radioactivity Variation With Earth-Sun Distance Resulting In Severe Nuclear Accidents, Jessica Solomon Apr 2021

Strontium-90 Radioactivity Variation With Earth-Sun Distance Resulting In Severe Nuclear Accidents, Jessica Solomon

Undergraduate Research Competition

Strontium-90 is the most common radioactive man-made isotope. It is much like calcium in that it relates closely to the bone and teeth. Exposure to Strontium-90 radiation can increase cancer rates in the bone or may result in the needed removal of an area. The danger is the isotope's half-life of 28.9 years meaning an increase in radiation. Two Geiger Muller (GM) detector systems consisted of NATS-1510/1520g tube connected to a NATS-EDUC-1510 single-channel analyzer were used in detecting Sr-90 radiation level. The radioactive sources used for these detectors were 0.09270.018 mCi of Sr-90. The Sr-90 detector system had a plateau …

Myoglobin Mutations In Varying Altitudes, Taylor Hackett Apr 2021

Myoglobin Mutations In Varying Altitudes, Taylor Hackett

Undergraduate Research Competition

Myoglobin is an oxygen carrying protein in muscle that allows adaptation to environmental stress regulation of hypoxia, which is the loss of oxygen in tissues to sustain proper function. Studies have indicated that muscles with higher myoglobin expression have enhanced ability to obtain oxygen in situations where hypoxic conditions occur. Building upon the study by Ma et al. (2013) focusing on high-altitude Tibetan antelope and low altitude sheep, myoglobin sequences were compared to determine if there were any significant mutations that led to change in taxa's ability to bind oxygen. This project phylogenetically analyzes seventeen additional sequences of the myoglobin …

The Early History Of Dark Matter, Luke Ignell Apr 2021

The Early History Of Dark Matter, Luke Ignell

Undergraduate Research and Engagement Symposium

Dark matter is a popular topic right now in physics. There are several prominent theories with respect to dark matter and its formation. One theory involves the WIMPs, or weakly interacting massive particles. The prediction is that these particles decoupled from equilibrium early in the universe after the “freeze-out” and now remain in high abundance. Another theory is the forbidden dark matter framework which describes dark matter as a thermal relic that annihilates into heavier states. A third theory describes a “freeze-in” mechanism; this scenario involves a feebly interacting massive particle, or FIMP, which never attains thermal equilibrium.

A Study Of The Internal Correlations Of Protein Sequences Using Non-Alignment Methods: Application Of The Burrows-Wheeler Transform, Joseph Buccinna Apr 2021

A Study Of The Internal Correlations Of Protein Sequences Using Non-Alignment Methods: Application Of The Burrows-Wheeler Transform, Joseph Buccinna

Undergraduate Research and Engagement Symposium

It is of long-standing interest to investigate the correlations within protein primary structures. Approaches across decades have looked primarily to alignment and database algorithms. We elect a different path by applying the Burrows-Wheeler transform (BWT) to archetypal proteins that include insulin, myoglobin, and lysozyme. We construct information-conserving transforms of protein sequences expressed by organisms placed at different points of the evolutionary tree. The transforms illuminate molecular evolution properties that are otherwise obscure in the sequences.

Synthesis Of A Folate-Mediated Photodynamic Therapy Agent And Application In Zebrafish Embryos, Aishah Kothawala, Allison Monterastelli, Phuong Pham Apr 2021

Synthesis Of A Folate-Mediated Photodynamic Therapy Agent And Application In Zebrafish Embryos, Aishah Kothawala, Allison Monterastelli, Phuong Pham

Undergraduate Research and Engagement Symposium

This project investigates the use of folate for targeted delivery of photosensitizers to tumors in photodynamic therapy. A photosensitizer, chlorin e6, produces toxic singlet oxygen through excitation by light, causing apoptosis. However, lack of selective targeting in PDT remains a challenge in cancer treatments. Folate, an essential vitamin, is used to serve as targeting agent since rapidly dividing cancerous cells over-express folate receptors. Folate is conjugated to Ce6 on a bovine serum albumin carrier and brought into the cell by endocytosis. The treatment is applied to zebrafish embryos because the embryonic cells possess an ortholog to the human FOLR1 receptor.

Subcloning Of Flag-Stn1-Flag From Pbabe-Puro To Pcl-Flag-Myc-Puro To Test Relationship Between Stn1 And Chemotherapeutic Agents, Anita Nasseri Apr 2021

Subcloning Of Flag-Stn1-Flag From Pbabe-Puro To Pcl-Flag-Myc-Puro To Test Relationship Between Stn1 And Chemotherapeutic Agents, Anita Nasseri

Undergraduate Research and Engagement Symposium

STN1 is a subunit of the CTC1-STN1-TEN1 (CST) protein complex. The CST complex is a highly conserved single-stranded DNA binding protein, that plays an important role in telomerase maintenance and promoting DNA replication under replication stress. Telomeres are regions at the end of the chromosomes that protect our DNA and maintain genome stability. Genome instability is one of the main causes of cancer and aging-related diseases. The activity of the STN1 component of the CST complex has been tied to rescuing genome stability under conditions of replication stress, and STN1 dysfunction has been associated with cancer and apoptosis. Therefore, further …

Engineering Design Project: 8 Hour Masks For College Students, Lauren David, Adam Horwitz, Julia Burns, Madeline Bryan Apr 2021

Engineering Design Project: 8 Hour Masks For College Students, Lauren David, Adam Horwitz, Julia Burns, Madeline Bryan

Undergraduate Research and Engagement Symposium

Since the start of the COVID-19 pandemic, masks have become part of everyone's daily lives. The purpose of masks is to protect the wearer from airborne infectious particles that could lead to illness. There are laws mandating masks to be worn indoors and outdoors to protect oneself and everyone to prevent the spread of COVID-19. For college students, masks are required to be worn for approximately 8 hours a day, so our main concern for this design project was to find a mask that is effective and affordable, while also providing comfort and breathability.

Survival Of The Fittest In The Long-Term Evolutionary Experiment, Alexa M. Nicholson Apr 2021

Survival Of The Fittest In The Long-Term Evolutionary Experiment, Alexa M. Nicholson

Undergraduate Research and Engagement Symposium

Experimental evolution is the study of evolutionary processes occurring in experimental populations under controlled laboratory conditions. Our research studies fitness in a long-term evolution experiment that observes evolutionary ecological interactions between previously isolated populations. Fitness refers to which evolutionary strains have the highest levels of reproductive success. We used fitness measurements for individual E. Coli populations to predict the dynamics when eleven populations were grown together. The differences between our predictions and results suggest there are complicated interactions occurring between the populations. Understanding these interactions could lead to a better comprehension of evolutionary biology and advance future predictions of adaptations.

Neutrino Oscillation, Kiet Anh Nguyen, Zachary T. Long

Undergraduate Research and Engagement Symposium

A neutrino is a subatomic particle that is at the forefront of modern-day particle physics research. The standard model predicts that The Standard Model of particle physics accurately predicts the presence and nature of subatomic particles. However, there are some issues that exist within the standard model predictions and one such issue pertains to neutrino masses. Neutrinos can be classified into three different species and can oscillate between the three. Neutrino oscillation is the evidence that led to the conclusion that neutrinos are massive particles.

Temporal Trends In The Abundance Of Litter On Lake Michigan Beaches Using Datasets Generated By Volunteer Clean-Up Events Over 20 Years, Sarah Maguire, Maxwell Menconi Apr 2021

Temporal Trends In The Abundance Of Litter On Lake Michigan Beaches Using Datasets Generated By Volunteer Clean-Up Events Over 20 Years, Sarah Maguire, Maxwell Menconi

Undergraduate Research and Engagement Symposium

Anthropogenic litter (i.e., trash; AL) is accumulating in ecosystems worldwide with negative ecological and economic impacts. On beaches, cigarette debris and plastic litter (e.g., bags, bottles, straws) are a primary component of AL. Both categories are also subject to prevention and policy strategies to reduce their use. Thus, we expect that over long time scales (i.e., > 10 years), AL on beaches from cigarette butts and plastic bags may be declining. We analyzed data collected by the long-running Adopt-A-Beach Program (administered by the Alliance for the Great Lakes), where volunteers record litter collected during clean ups. We compared the total AL, …

Questioning The Mind/Body Dichotomy In Science Communication, Masha Bandouil Apr 2021

Questioning The Mind/Body Dichotomy In Science Communication, Masha Bandouil

Undergraduate Research and Engagement Symposium

The mind/body dichotomy established in Western society has created a form of knowledge acquisition based in the brain. However, rooted in human instinct, the body houses a language in itself that can be effective in communicating knowledge to others in a way that isn't based on level of education or access to specialized knowledge. This research explores the use of movement in communicating scientific knowledge and making it more accessible to the general public. Through a partnership with The Sarnoff Center of Genetics, I created a series of dance films illustrating genetic principles and diseases that disproportionately affect the Jewish …

A Quantitative Evaluation Of The Benefits Of Writing Tutoring In First-Year Writing Seminars, Allison Monterastelli Apr 2021

A Quantitative Evaluation Of The Benefits Of Writing Tutoring In First-Year Writing Seminars, Allison Monterastelli

Undergraduate Research and Engagement Symposium

Writing centers are a vital resource that offer support for various writing skills. Despite their importance, research on the benefits of writing tutoring has largely relied on anecdotal evidence. Further, attempts at quantified research have faced two barriers. First, student use of writing support depends on incentivization or voluntary involvement, which correlates with highly-grade motivated students. Second, evidence of improvement has relied on subjective measures such as professor assigned grades and student satisfaction surveys. Our study bypasses these limitations through mandatory participation across first-year writing seminars and the application of an objective rubric to quantify the benefits of writing tutoring.
