Effects Of Alk2 Deficiency On T Cell Fate And Regulatory T Cell Populations, Jalyn Reeves, Afia Salsabil Alam

Knowledge and Creativity Expo

Regulatory T cells (Tregs) are central to immune tolerance, and their lineage stability is established during thymic development and maintained in the periphery through tightly regulated signaling networks. Members of the BMP receptor family have been implicated in T-cell differentiation, yet the specific role of the type I receptor ALK2 in shaping cell fate and sustaining the regulatory program remains unclear. To examine how ALK2 contributes to T-cell development, we generated ALK2-knockout murine chimeras and analyzed lymphoid populations from the thymus, spleen, and peripheral tissues. Thymocytes and lymphocytes were isolated and stained with antibody panels to identify developmental subsets and …

Predator-Prey Responses Of The Clamworm Alitta Succinea To Direct Interaction With Crabs And Chemical Cues, Shyann Mcclain, Gloria M. Massamba N'Siala

Knowledge and Creativity Expo

Predator–prey interactions in marine benthic systems can have important indirect effects mediated through environmental signaling. Predators can reveal their presence through the release of chemical cues, influencing the activity and feeding rates of other potential prey through non-consumptive effects, which may ultimately shape energy allocation and survival in targeted populations. Along the Atlantic coast of the United States, predatory crabs overlap spatially with polychaete prey such as the clamworm Alitta succinea, creating consistent predation pressure. This study will set up the experimental system needed to examine the physiological responses of clamworms to both direct and indirect predation cues under controlled …

Seasonal Activity Pattern Of Ambrosia Beetles In Southeast Virginia, Umme H. Akter, Sajrim Chowdhury, Deborah A. Waller

Knowledge and Creativity Expo

Ambrosia beetles (Curculionidae: Scolytinae) are wood-boring insects that influence forest ecosystems through fungal symbioses, rapid host colonization, and invasive species dynamics. Despite their ecological importance, seasonal activity patterns remain poorly characterized in southeastern Virginia. This study integrates field trapping and statistical modeling to examine species-specific seasonal activity across two forested sites in Norfolk, Virginia. Beetles were monitored using ethanol and essential oil-baited bottle traps alongside ethanol-soaked bolt traps. Overall abundance peaked in April, indicating strong early-season emergence. Ethanol-baited traps captured 3-7 times more beetles than essential oil traps, and negative binomial generalized linear models confirmed bait type as a significant …

Protocol For Egg Mass Preservation And Its Efficacy In The Marine Annelids Ophryotrocha Labronica, Brennan Sinclair, Gloria Massamba-N'Siala

Knowledge and Creativity Expo

Accurate measurement of egg size is essential for understanding reproductive investment and developmental patterns in Ophryotrocha labronica, but standard protocols require imaging fresh eggs, limiting sample throughput. This study tested whether short‑term preservation in 4% formalin alters egg size and developed a workflow to support more efficient developmental observations. Egg masses were divided into subsamples and measured after 0, 2, and 7 days of preservation. Using a linear mixed‑effects model, we analyzed 224 eggs from 25 masses to evaluate the effect of preservation time while accounting for variation among clutches. Preservation time had no significant effect on egg size, …

Touching Lives With Empathy And Assurance In Medicine (Team): An Experiential Palliative Care Medicine Program For Medical Students, Kevin A. Barnes, Simone K. Schumaecker, Madeline L. Dunstan, Marissa C. Galicia-Castillo

Knowledge and Creativity Expo

Palliative Care Medicine (PCM) education presents unique challenges as core competencies like communication, response to grief, and engaging seriously ill patients are difficult to teach through classroom instruction. Despite didactics and modules, many medical students report feeling underprepared for end-of-life discussions. Emerging evidence suggests that experiential learning, particularly one-on-one interactions with patients, reduces learner insecurity and deepens understanding of serious illness. The Touching Lives with Empathy and Assurance in Medicine (TEAM) program at Lake Taylor Transitional Care Hospital was developed to address this gap through a structured, longitudinal PCM experience. This project analyzes the program’s design, implementation, and early participation …

Existential Isolation As A Barrier To Veteran Employment Satisfaction: Implications For Workplace Reintegration, Caleb Blanchard

Knowledge and Creativity Expo

Veterans’ reintegration into civilian society often involves recurring problems, particularly within workplaces. More specifically, 40% of veterans report that transitioning into civilian life is much harder than expected, and 80% report that other non-veterans do not understand their problems. Recent work also finds that veterans report feeling more existentially isolated (i.e., the perception that other people do not understand their experiences or worldview) than non-veterans, which may underly these issues with effective reintegration. In this longitudinal study, we examine whether reducing these feelings of existential isolation through “I-sharing” (i.e., the perception of sharing a subjective experience with another person) in …

Remediation Of Ammonium Perrhenate Via Tris(2,2’-Bipyridine)Ruthenium(Ii) Chloride, Kaylin L. Thomas, Sandra A. Abdellah, Alvin A. Holder

Knowledge and Creativity Expo

Pertechnetate (TcO₄⁻) is a persistent radioactive byproduct resulting from the decay of uranium-235 or plutonium-239 in the nuclear fuel cycle. Its high environmental mobility, long half-life, and significant beta radiation make TcO₄⁻ a critical contaminant. Structurally tetrahedral and water-soluble, TcO₄⁻ behaves similarly to the sulfate anion, facilitating its rapid introduction into ecosystems.

It bioaccumulates in lower-level organisms, propagating radioactive and toxic effects through food chains. In mammals, technetium-99 accumulates in the thyroid and may also impact fetal development. Its small charge, chemical stability, and solubility present significant challenges for effective remediation.

Current remediation methods often suffer from poor selectivity, dependence …

Reconstructing 5000 Years Of Hurricane Activity In Holyrood Pond Using Sediment Core Analysis, Jamie Mclaulin, Arielle Nogueira, Elizabeth Wallace

Knowledge and Creativity Expo

Hurricanes are hazardous and costly events that annually negatively impact people that live in coastal areas in North America.  The current observational record of hurricanes is short (1970- present) and does not offer insight into the effects of climate change on hurricane frequency.  One method of improving and extending our observational record of hurricanes is to reconstruct paleohurricanes using sediment cores.  These cores record hurricane activity in the form of coarse-grained overwash layers that are deposited when hurricanes move sand from beaches into backbarrier ponds.  In this project, we analyzed sediment cores from Atlantic Canada to locate coarse-grained storm layers …
