Another Look Into The ~950-Year-Old Glass Mountain Rhyolite Tephra: New Insights Into Volume, Eruption Column Height, And Geochemistry, Bodhi Merrill

IdeaFest 2026

This study examines the ~950-year-old Glass Mountain rhyolite tephra at Medicine Lake Volcano (MLV) in northeastern California. I use field observations and mapping of the dispersal of erupted material to estimate the total volume of tephra erupted, the maximum height of the eruption column during the explosive phase, and how the eruption evolved over time in terms of mass flux, vent erosion, and magma supply. In addition, I use the petrologic and geochemical properties of samples to offer insights into the pre-eruptive storage conditions of the erupting magmas. MLV is designated as a "high-threat volcano" by the USGS highlighting the …

Genetically Driven Lipid Dysfunction And Neuroinflammation: An Agent-Based Model Of Alzheimer's Disease, Anthony Wolfe, Mack Kona, Sela Raisl, Enrique Lopez, Kamila Larripa

IdeaFest 2026

Microglia are immune cells in the brain that switch phenotypes to maintain neural health, but disruptions in this regulation may contribute to Alzheimer’s Disease (AD). We developed an agent-based model to link cell mechanisms to tissue-level patterns, incorporating both individual cell responses to localized signaling and the effects of APOE and TREM2 variants on microglial metabolism and clearance. Through computational experiments, we simulate how impaired lipid clearance and sensing lead to a pro-inflammatory microglial population and chronic inflammation. Our framework offers insight into how local dysfunction progresses to persistent neuroinflammation and promotes conditions like AD.

Built By Community: How Serving Others Has Inspired My Future, Naomi Garcia

IdeaFest 2026

As a College Corps Fellow, I served at Centro Del Pueblo (CDP). The projects and work I was a part of allowed me to serve Indigenous, Migrant, and Latinx families and communities throughout Humboldt. Through advocacy, cultural preservation, and decolonial practices, I was able to experience the elements of creating and collaborating on community-led initiatives, as well as learn how to be in service of others as an aid, artist, translator, educator, organizer, and human.

Everybody Was Kung Fu Fighting!, Robert Broadway

IdeaFest 2026

Kung Fu has an unrivaled ability to motivate children to exercise. I believe that providing a martial arts manual offers the most effective path to achieving accessibility and inclusion in Physical education. The manual will help the martial arts program by offering step-by-step instructions that can be adapted to meet individual needs. The manual's cover will be designed to look like a traditional martial arts manual while the inside resembles a colorful children’s book.

Lightning-Driven Wildfire Risk And Forest Loss In Six Rivers National Forest, Jonathan David Juarez, Dr. Rachel Torres

IdeaFest 2026

Forest ecosystems support biodiversity, stabilize soils, and regulate water but face increasing threats from wildfire and drought under climate change. Six Rivers National Forest in Humboldt County, California, is vulnerable due to dense biomass, dry summers, and dominant species like coastal redwood, Douglas fir, and tanoak. This study combines CAL FIRE wildfire records (1950-2025) with remote sensing (2014-2024) to assess wildfire-forest loss relationships. Hansen Global Forest Change and MODIS data, along with NDVI and PDSI, show strong overlap between wildfire and forest loss, with rising lightning-caused ignitions after 2000, suggesting climate-driven fire dynamics.

Black Humboldt, Bailey Linares

IdeaFest 2026

This project explores my work as a College Corps fellow with Black Humboldt, a nonprofit supporting Black residents in Humboldt County. Through community events, outreach, and relationship-building, I contributed to creating safe, inclusive spaces in an underrepresented region. This work addresses issues of visibility, isolation, and access to culturally relevant resources. By translating concepts of equity and representation into practice, the project highlights how grassroots efforts can strengthen community connection, belonging, and support.

Sensors And Smart Food Packaging For Supply Chains: Bridging Expiration Dates And Actual Perishability, Muhammad Umar Azam, Jolina Rodrigues, Mohamed Hamid Salim, Sarath Haridas Kaniyamparambil, Khalid Askar, Imane Belyamani, Blaise L. Tardy, Nouha Alcheikh

All Works

The food supply chain is undergoing critical changes to minimize environmental hazards, such as those associated with packaging, and reduce food waste and loss. One of the critical components of the latter is associated with the high variance in the perishability of individual foodstuffs. Herein, we review the state of the art in smart sensor systems and emphasize the critical role they could play in addressing the mismatch between “batch” based expiry dates and individual food products’ time-dependent responses to spoilage. Following a brief overview of food shelf life and associated legislation, a subsequent section summarizes the development of sensors …

Source & Solidarity, Sari Mazzurco

Michigan Law Review

Trademark law has become the new frontier of unionbusting. Companies like Trader Joe’s, Starbucks, and Medieval Times have brought unprecedented suits against their employee unions for trademark infringement in relation to their organizing activities. This sort of litigation puts courts in the difficult position of reconciling trademark protection with unionization rights. Their attempts to apply standard trademark doctrines in this context reveal a deeper problem: Current trademark law is incoherent when applied to labor unions.

This incoherence stems from a disconnect between current trademark law and the original purpose behind its application to labor unions. This Article recovers that basis …

Blue Carbon Ecosystems As Climate Solutions: Sequestration Across Coastal And Marine Environments, Allison K. White, Richard J. Kline, Md. Saydur Rahman

School of Earth, Environmental, & Marine Sciences Faculty Publications

Blue carbon ecosystems (BCEs) such as mangroves, salt marshes, and seagrasses, sequester significant amounts of CO2 from the atmosphere. These ecosystems capture and store carbon in biomass and sediments over long periods. Other marine ecosystems, including the open ocean, kelp forests, bivalve reefs, and coral reefs, have been excluded from the BCEs, but they have the potential to serve as crucial blue carbon sinks or to support adjacent BCEs. Climate change, however, poses severe threats to these ecosystems. Rising sea levels, increasing temperatures, and ocean acidification can lead to habitat loss, reduced biodiversity, and impaired carbon sequestration capacity. Consequently, anthropogenic …

A Review Of Natural Hydrogen Generation From Iron-Rich Rocks: Mechanisms, Influencing Factors, Techniques, And Knowledge Gaps, Kaveh Moghanirahimi, Lionel Esteban, Marina Pervukhina, Muhammad Arif, Stefan Iglauer, Alireza Keshavarz

Research outputs 2022 to 2026

Natural hydrogen has emerged as a promising clean energy resource with significant potential for large-scale subsurface production. Among the various geological sources, water–rock interactions involving iron-bearing rocks are among the most extensively studied pathways for natural hydrogen generation. This study provides a comprehensive review of hydrogen production from iron-rich lithologies, including mafic and ultramafic rocks, iron oxides, iron carbonates, and peralkaline granites. The fundamental mechanism involves the reduction of water coupled with the oxidation of ferrous iron to ferric iron under anoxic conditions. Key processes, including serpentinization, magnetite alteration, and siderite decomposition, are critically evaluated using experimental and modelling data. …

Decoding Surface Chemistry Effects On Polystyrene Nanoplastic Fouling In Plasma-Grafted Pes Membranes With Distinct Functional Groups, Mohadeseh Najafi, Javad Farahbakhsh, Ebrahim Mahmoudi, Michael Johns, Masoumeh Zargar

Research outputs 2022 to 2026

Nanoplastic (NP) fouling remains a key challenge for ultrafiltration (UF) membranes, yet systematic, controlled comparisons of how membrane functional groups govern NP-membrane interactions are still limited. Here, the role of membrane surface chemistry was systematically investigated using a controlled comparative framework based on plasma-grafted polyethersulfone (PES) UF membranes tailored with structurally comparable methacrylate monomers bearing distinct terminal functionalities, including mono-2-(methacryloyloxy)ethyl succinate (MMES, -COOH), N-[3-(dimethylamino)propyl] methacrylamide (DMAPMA, -N(CH3)2), and [2-(methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)ammonium hydroxide (SBMA, zwitterionic). Comprehensive characterisations supported successful surface grafting while preserving the membrane substructure. Fouling and separation were assessed using polystyrene (PS) NPs having different surface chemistries, i.e., PS, PS-COOH and …
