Plant–hummingbird interactions are considered a classic example of coevolution, a process in which mutually dependent species influence each other's evolution. Plants depend on hummingbirds for pollination, whereas hummingbirds rely on nectar for food. As a step towards understanding coevolution, this review focuses on the macroevolutionary consequences of plant–hummingbird interactions, a relatively underexplored area in the current literature. We synthesize prior studies, illustrating the origins and dynamics of hummingbird pollination across different angiosperm clades previously pollinated by insects (mostly bees), bats, and passerine birds. In some cases, the crown age of hummingbirds pre-dates the plants they pollinate. In other cases, plant …

Visual Parsing Algorithms For An Equitable Augmented Reality Learning System, Pushpita Saha '25, Matthew L. Furber Mfa, Paul W. Bible

Annual Student Research Poster Session

Giving instructions for a character to navigate around a scene provides a simple analog for the planning needed in computer programming. While many children’s navigation games exist, most require the child to use a combination of input devices such as keyboard, mouse, and controllers for play. Children under the age of five may struggle to use a mouse, but they can easily construct the plans needed for such a game. This research explores layout and graph connectivity algorithms to connect tactile game pieces for a navigation game. A web camera identifies the position of action cards and numerical modifiers (card: …

Avoidance Behavior Of Oppia Nitens (Oribatid Mites) To Herbicide: Glyphosate Compared To Microplastics In Standard Artificial Soil., Thi Doan '27, Philips Akinwole

Annual Student Research Poster Session

Despite growing public interest in environmental issues, awareness of contaminants affecting soil organisms remains broadly lacking, despite decades of research. This study investigated the impacts of a common herbicide; glyphosate, (Roundup), on the avoidance behavior of Oppia nitens - a soil mite species used as an indicator of soil health, and soil moisture content. The study involved exposing O.nitens to standard artificial soil treated with glyphosate concentrations ranging from 47.8 to 501.6 mg/kg. Avoidance behavior was assessed by observing mite distribution between treated and untreated soil over a 48-hour period. Results demonstrated clear avoidance behavior at higher glyphosate concentrations (501.6 …

The Origins Of The Major Questions Doctrine, Rachel Rothschild

Indiana Law Journal

In a series of recent cases, the Supreme Court has invoked the newly named “major questions doctrine” to strike down agency regulations that protect public health and the environment. Several Justices have argued that while the name “major questions” may be new, these decisions are simply the latest iteration in a longstanding effort of the courts to curtail the explosive growth of the administrative state since 1970. The first paradigmatic example of this line of cases is the 1980 “Benzene” case, in which the Supreme Court set aside the Occupational Safety and Health Administration (OSHA)’s new workplace standards for the …

After spending two full months living on a remote island off the coast of Maine, I had a difficult time adjusting to mainland life again; the noise, the people, the lack of birds a shock to my system after getting used to such a different way of living. In this piece, I wanted to capture the feeling of becoming part of Petit Manan island, trying to learn the language of the land and the birds, and then the feeling of loss and change once I left. I hope readers can experience the feeling of falling in love with the island …

How Did The Deer Cross The Road? Reducing Habitat Fragmentation And Wildlife-Vehicle Collision Deaths Through Connective Conservation In The South Mountain Region, Pennsylvania, Jack B. Joiner, Emily R. Kreider, Thomas H. Manning, Madison E. Rowell

Student Publications

While some deleterious effects of road networks and the vehicles that travel them– such as pollution, fossil fuel extraction, and carbon emissions– are widely recognized, their significant role in causing an estimated one million wildlife deaths per day (Shilling et al., 2021) and contributing to habitat loss and degradation, the leading causes of global biodiversity decline (Pinto et al., 2023), has garnered less attention. Connective conservation policies, such as designating wildlife corridors and constructing wildlife crossings on roadways, have been proposed as a means of mitigating these repercussions. This study proposes a connective conservation plan addressing the logistics of a …

The Stockholm Resilience Centre has concluded that the number of "planetary boundaries" we are crossing has increased from three in 2009, when the Centre's researchers first introduced the concept, to six in 2023. Crossing these boundaries means humans are changing basic attributes of planetary systems to the point of risking the future of civilization. And the distinction between "safe" and "just" planetary boundaries raises questions regarding how to conceptualize the "good life." In this latest in a biannual series of essays, members of the Environmental Law Collaborative explore conceptions of the "good" as well as the various elements necessary to …

Unpacking English Language Teachers’ Perceptions And Practices Of Translanguaging: A Case Study Of Secondary Schools In China, Yuling Chen, Fan Fang, Weilei Zhang

Journal of English and Applied Linguistics

Translanguaging has gained prominence as a viable tactic to assist the language learning of L2 learners due to the increasing variety of classrooms globally. Translanguaging pedagogy has been recently studied in diverse contexts. However, most of the research on translanguaging, especially in the Chinese context, is focused on higher education. Limited attention has been paid to secondary school. Therefore, this qualitative case study aims to fill this gap by investigating how language educators employ translanguaging in their English teaching in secondary schools. Data was collected from 4 Chinese EFL teachers across 2 secondary schools through classroom observation and semi-structured interviews, …

The Columns From “The Tomb Of Charlemagne” Between Aachen And The Louvre: A Modern Spoliation Saga, Brigitte Buettner

Art: Faculty Publications

In September 1794, the French army, after conquering much of Belgium and the Netherlands, marched into Aachen. This early campaign of military conquest turned into the first laboratory for the systematic plunder of cultural assets enacted by various post-revolutionary and Napoleonic regimes from 1794 to 1815. Works of art “liberated” from the tyranny of aristocratic and religious ownership were earmarked for the newly opened Musée Central des Arts (now the Louvre) to showcase the enlightened cultural supremacy of Paris. From Aachen, the conquerors took more than the usual loot of movable assets: they “extracted” some forty columns from Charlemagne’s famed …

Shocking Sentences, John B. Meixner Jr.

Indiana Law Journal

Harsh recidivist sentencing penalties, like three-strikes laws, have been criticized heavily among both academics and practitioners on a number of different grounds. Most arguments focus on how sentences arising from these penalties are disproportionate—that there is no sensible relationship between the wrong committed and the sentence imposed. Those critiques are valid, but there’s another important problem with recidivist sentencing penalties that has been overlooked: They lead to sentences that are totally unexpected—indeed, shocking—to the defendants who face them. Many recidivist sentencing penalties cause large leaps in sentencing exposure that amount to exponential growth when compared with a defendant’s prior sentences. …

Corporate Civil Disobedience, Susanna K. Ripken

Indiana Law Journal

Classic theories of civil disobedience endorse the right of individuals to commit illegal acts to protest unjust laws and policies. Acts of civil disobedience have historically played a central role in exposing injustice and producing vital legal and social change. The literature on civil disobedience is vast; political and legal theorists have long recognized the contributions of individual legal resisters in the ongoing pursuit of a just society. Little attention has been given, however, to intentional lawbreaking by organizational entities that seek to protest unjust, illegitimate, or discriminatory laws. This Article addresses that gap by exploring the prospect of corporate …

Endosomal Fusion Of Ph-Dependent Enveloped Viruses Requires Ion Channel Trpm7, Catherine A Doyle, Marta E Stremska, Louis-Marie Bloyet, Cassandra E Thompson, Paul W Rothlauf, Sean P J Whelan, Et Al.

2020-Current year OA Pubs

The majority of viruses classified as pandemic threats are enveloped viruses which enter the cell through receptor-mediated endocytosis and take advantage of endosomal acidification to activate their fusion machinery. Here we report that the endosomal fusion of low pH-requiring viruses is highly dependent on TRPM7, a widely expressed TRP channel that is located on the plasma membrane and in intracellular vesicles. Using several viral infection systems expressing the envelope glycoproteins of various viruses, we find that loss of TRPM7 protects cells from infection by Lassa, LCMV, Ebola, Influenza, MERS, SARS-CoV-1, and SARS-CoV-2. TRPM7 ion channel activity is intrinsically necessary to …

A Retrospective Analysis Of Sheep Generated By Somatic Cell Nuclear Transfer, Ying Liu, Rusty Stott, Misha Regouski, Zhiqiang Fan, Iuri Viotti Perisse, Tayler Patrick, Jacob Keim, Qinggang Meng, Irina A. Polejaeva

Animal, Dairy, and Veterinary Science Faculty Publications

Somatic cell nuclear transfer (SCNT) is one of the primary methods for production of genetically engineered sheep, which allows for gene editing or transgene introduction in somatic cells. The use of SCNT eliminates the risk of genetic mosaicism in embryos and animals that is commonly observed after zygote micromanipulations. This retrospective analysis of SCNT in sheep performed at Utah State University, spanning from 2016 to 2021, examined parameters that may impact pregnancy and full-term development, including donor oocytes (donor age), donor cell lines, SCNT parameters (time of oocyte activation following SCNT, number of transferred embryos, in vitro maturation and culture …

Deletion Of Tissue Factor Pathway Inhibitor Isoform Beta Or Gamma, But Not Alpha, Improves Clotting In Hemophilic Mice, Irem Eldem, Lilian Antunes-Heck, Renumathi Subramanian, Nina M Lasky, Katrina Ashworth, Jorge Di Paola, Thomas J Girard

2020-Current year OA Pubs

BACKGROUND: Tissue factor pathway inhibitor (TFPI) regulates tissue factor-triggered coagulation. Humans and mice express transcripts encoding for multidistributed (endothelial, platelet, and plasma) 3-Kunitz domain TFPIα and endothelial membrane-anchored 2-Kunitz TFPIβ. Mice express a third transcript, γ, that encodes plasma lipoprotein-associated 2-Kunitz TFPI. In humans, proteolysis of α and/or β produces plasma lipoprotein-associated 2-Kunitz TFPI at lower levels. In clinical trials, monoclonal antibodies that target all TFPI isoforms extend coagulation and correct bleeding in hemophilic patients but with some thrombosis risks.

OBJECTIVES: To determine the impact of TFPI isoform-specific deletions on promoting clotting in hemophilic mice.

METHODS: Engineered TFPI isoform-specific, hemophilic …
