title: Polyketide synthase-derived sphingolipids mediate microbiota protection against a bacterial pathogen in C. elegans

description: Mass spectrometry imaging data for the study Peters et al. <br><br>Abstract: Protection against pathogens is a major function of the gut microbiota. Although bacterial natural products have emerged as crucial components of host-microbiota interactions, their exact role in microbiota-mediated protection is largely unexplored. We addressed this knowledge gap with the nematode Caenorhabditis elegans and its microbiota isolate Pseudomonas fluorescens MYb115 that is known to protect against Bacillus thuringiensis (Bt) infection. We find that MYb115-mediated protection depends on sphingolipids (SLs) that are derived from an iterative type I polyketide synthase (PKS), PfSgaAB, thereby revealing a non-canonical pathway for the production of bacterial SLs as secondary metabolites. SL production is common in eukaryotes but was thought to be limited to a few bacterial phyla that encode the serine palmitoyltransferase (SPT) enzyme, which catalyses the initial step in SL synthesis. We demonstrate that PfSgaB encodes a pyridoxal 5'-phosphate-dependent alpha-oxoamine synthase with SPT activity, and find homologous putative PKSs present across host-associated bacteria that are so far unknown SL producers. Moreover, we provide evidence that MYb115-derived SLs affect C. elegans defence against Bt infection by altering SL metabolism in the nematode host. This work establishes SLs as structural outputs of bacterial PKS and highlights the role of microbiota-derived SLs in host protection against pathogens.

title: Effects of the Breast Tissue Microenvironment on the Progression of Breast Cancer

description: Breast cancer is the second most common cancer in women. The breast tumor will remodel its surrounding environment to make it more permissive to invasion and eventual metastasis through alterations of the extracellular matrix (ECM), cells, and secretions. Examining these changes proves important as they give possible targets for therapeutics. There are multiple different risk factors for breast cancer and they all can cause changes in the normal breast environment. These changes in the normal breast microenvironment are critical to investigate as they can allow for the progression of breast cancer.
In this dissertation, first we examined the normal breast structure of mice groups with different generations of obesity. These matrices showed differences in the collagen structure, namely collagen curvature, that breast cells responded with increased migration and invasion when seeded on the ECM from mice with a high-fat dam. We then investigated if an increase in leptin concentration caused alterations in collagen curvature. Next, we investigated 3D tumor models and created a 3D bioprinted human obesity breast tumor model. After being characterized, both 2D breast cancer cell culture and our 3D tumor spheroid model were treated with different extracellular vesicle (EV) groups where we saw an increase in cell migration and invasion for those constructs treated with EVs from fibroblasts closer to the tumor. Finally, we examined the impact of chemotherapeutics on normal breast fibroblast ECM production. Those fibroblasts treated with doxorubicin had increased reactive oxygen species production and the ECM they generated had a curvier collagen structure, which caused breast cancer cells to have increased migration and invasion when seeded onto the generated ECM. Overall, through these studies we were able to show how different changes in collagen structure or proximity to a tumor can affect the progression of breast cancer cells to be more motile and invasive.

title: CoastBench: A global training dataset for coastal classification using satellite imagery and elevation data

description: CoastBench is a global training dataset for coastal classification using satellite imagery and elevation data. It contains approximately 1,800 expert-labeled samples from coastlines around the world. Each sample includes labels for four coastal attributes across the cross-shore coastal profile: sediment type, coastal type, presence/absence of built environment, and presence/absence of human-made coastal defenses.

Labels were assigned via a custom web interface using high-resolution satellite imagery. All samples are spatially anchored to the Global Coastal Transect System (GCTS) grid.

title: “Genie Replication Package: Resolution of Kryptos K4 via Berlin Clock Route and Substitution Funnel”

description: Research DescriptionThis work presents a replication-ready implementation of the <b>Genie Engine</b>, an algorithmic framework designed to evaluate candidate solutions for the final section (K4) of the <i>Kryptos</i> sculpture at CIA Headquarters. The Kryptos sculpture, created by artist Jim Sanborn in 1990, contains four encrypted panels; the first three have been solved, while K4 (97 characters) has remained unsolved for over three decades.The Genie framework operationalizes a set of structured constraints drawn from both artistic and statistical cues:<b>Berlin Clock Route Hypothesis</b>The ciphertext is arranged in bands (4–4–11–4), cycling in a boustrophedon pattern inspired by the Berlin Clock.An offset of 21 aligns cribs with cipher windows.Substitution alphabets vary according to a periodic state schedule (k mod 3).<b>Crib Anchoring</b>Known plaintext fragments revealed by the artist (“EASTNORTHEAST”, “BERLINCLOCK”) are enforced as anchors.Bucket consistency ensures that the same ciphertext symbol maps to the same plaintext character within the same row-state.<b>Evaluation Metrics (Genie Match Test)</b><b>Motif Hits</b>: Rewards coherent instructional motifs (BEARING, DEGREES, GRID, etc.).<b>Tail Repeat Alignment</b>: Rewards repeated ciphertext symbols mapping consistently at the tail (with emphasis on E/R/S letters).<b>MDL Proxy</b>: Encodes a minimum-description-length bias favoring reuse of common English letters (E, R, S, T, N, O, G) while penalizing rarities.Final score = 3·H(P) + 2·T(P) + M(P).<b>Empirical Validation</b>The assembled plaintext reads:<br><i>“TO SET THE EAST-NORTHEAST HOUR BY BEARING BERLIN CLOCK DEGREES GRID POINT NORTHWEST TO FIND GROSSER STERN.”</i>Across 10,000 randomized decodes (under the same structural constraints), no candidate matched or exceeded the Genie baseline score (p ≤ 0.0001).Comparative testing shows “GROSSER STERN” closure yields superior alignment and compression relative to alternatives (e.g., “VICTORY COLUMN”).ContributionsProvides a <b>self-contained Python package</b> enabling independent replication and stress-testing of the solution.Demonstrates a statistical pathway for ruling out random coincidence, offering a strong empirical argument for solution validity.Frames the K4 plaintext not merely as an arbitrary phrase, but as a coherent <i>instructional directive</i> consistent with the sculpture’s prior panels.Broader ImpactThe Genie Package offers a transparent methodology for cryptanalysis of constrained historical ciphers. Its approach balances structural hypothesis (Berlin Clock route), empirical crib-seeding, and statistical validation, bridging artistic interpretation and computational cryptography. This contributes both to the cultural-historical record of Kryptos research and to broader questions of how cryptographic artifacts may encode layered meaning.
