Passive Integrated Transponders: An Effective Marking Technique For Individual Identification Of Anaxyrus Fowleri?, Emily Haner

Steeplechase: An ORCA Student Journal

With the rise of fungal disease such as Chytridiomycosis causing massive population declines for many species of frogs and toads (order Anura), specific conservation strategies are needed now more than ever. In many cases, being able to mark and identify individuals is a necessary step in developing an effective conservation plan. Individual identification allows researchers to obtain accurate population estimates, which are needed to test the progress and validity of conservation management decisions. However, due to their unique life history, including cutaneous respiration, Anurans are among the most difficult wildlife species to effectively mark for individual identification. In a mesocosm …

Intelligence Without An 'I': "I Think, Therefore I Am", Darshan Shah

Osmosis Magazine

From Billie Eilish hits to corny Pinterest tattoos, Rene Descartes’ famous dictum is embedded in modern Western consciousness. But, like all philosophy, it operates within a paradigm of assumptions about the world that remain open to challenge. Over centuries of Cartesian influence, these assumptions have become invisible in our philosophies and sciences, informing the very questions we ask about intelligence and where we search for it in the world.

Campus As A Living Lab At Ur: What’S Working & What’S Next, Jack Dupuy

Osmosis Magazine

Living labs—real-world experimental environments where diverse stakeholders ranging from local communities and businesses to universities and governments can collaboratively develop, test, and refine solutions—have become an increasingly popular method for tackling complex societal challenges in areas such as energy, urban planning, and environmental sustainability. Unlike controlled laboratory settings, living labs leverage real-world conditions to test innovations in authentic contexts, fostering systemic change by aligning research with local needs.

Droughts, Destruction, And Displacement: How Climate Change Exacerbates Violence In The Sahel, Stevi Dugas

Osmosis Magazine

February 2023 through January 2024 marked the first 12- month period that global average temperatures exceeded the 1.5°C benchmark proposed in the Paris Climate Agreement, indicating early signs of coming dangerously close to exceeding a permanent 1.5°C increase in global average temperatures. Permanently exceeding the 1.5°C benchmark is expected to lead to increasingly frequent and dangerous extreme weather events such as droughts and wildfires, while also increasing the risk of climate tipping points such as collapse of coral reef systems (UN, n.d.). Though no place is safe from the effects of climate change, few places on Earth will be hit …

What should you do? Will changing your choice increase your chances of winning the car - or or does it make no difference at all?

Myth Or Fact: Does Teethwhitening Really Work?, Garrett Mayover

Osmosis Magazine

Teeth whitening has rapidly gained popularity as one of the most sought-after dental cosmetic procedures today. Once an exclusive treatment performed primarily by dental professionals, it has now expanded into the mainstream market, with store shelves stocked full of “natural” alternatives and “affordable” whitening strips. But the pressing question remains: do these strips actually work, or are they just a marketing gimmick? This article aims to uncover the truth. We will first explorethe science behind teeth whitening and then delve into the effectiveness andpotential drawbacks of these popular over-the-counter products.

The Science Behind Covid Testing, Zion Kim

Osmosis Magazine

On March 11, 2020, the World Health Organization (WHO) officially declared a COVID-19 pandemic (“CDC…”, 2024). We all remember the days we had to wear masks, shove cotton swabs into our noses and mouths, and quarantine ourselves from others after being infected by the COVID-19 virus. We take this test all the time and trust their accuracy, but we never stop to ask how they work. We all know that a double line indicates an infection of COVID-19, but why?

It’s a simply iconic scene from a simply iconic movie; in the cult classic film The Princess Bride, the protagonist Westley faces off against the scoundrel Vizzini in a battle of wits to rescue his true love. The challenge is simple: each man is given a chalice, one of them containing poisonous iocane powder. Colorless, odorless, tasteless, and soluble in water, Vizzini must choose the unpoisoned chalice off wits alone. However, he chooses wrong, dying instantly.

Not Human Enough: The Origins Of The Uncanny Valley, Franklin Young

Osmosis Magazine

Why do we feel creeped out when we see something almost human—like a lifelike robot or a bad CGI character? This phenomenon, known as the uncanny valley, describes the uncomfortable emotional response humans experience when encountering entities that appear nearly, but not quite, human. First introduced by Japanese robotics professor Masahiro Mori in 1970, the concept suggests that as objects become more humanlike in appearance, our emotional response to them becomes increasingly positive —until reaching a point where subtle imperfections trigger strong feelings of revulsion.

Identifying The Factors Affecting The Survival Of Trauma Patients Using Logistic Regression Analysis, Maggie Smith

Steeplechase: An ORCA Student Journal

Numerous predictors affect the clinical outcomes such as survival status, a binary outcome variable, of patients with physical trauma. Logistic regression is one of the widely used methods to analyze relationships between a set of predictors with a binary outcome variable. In this study, we built a logistic regression model for a binary outcome variable, Hospital Discharge Status (HDS). Predictors included in this analysis are arrival time, age, trauma level, injury severity score, arrival heart rate, arrival blood pressure, length of hospital stay, time from injury to arrival at the BC, patient transfer or direct admittance, mode of transfer, time …

Design And Evaluation Of Geopolymer Composite As A Potential Sorbent Of Heavy Metals From Water, Ebtesam Mohammed Alghafri

Thesis/ Dissertation Defenses

Reducing the levels of heavy metals in water is crucial, given their severe environmental and health impacts. Various methods exist for heavy metals removal. Yet, they mostly come with multiple drawbacks, such as costly treatments and limited efficiency. Previous studies have found geopolymer to be a promising sorbent because it is synthesized using by-product materials, making it an eco-friendly and economically sustainable alternative. Limited studies explored the sorption potential of fly ash-slag blended geopolymers; none examined the effect of mix design factors synergically on sorption, mechanical properties, and durability, and few considered solution characteristics and operating conditions simultaneously. Therefore, this …
