Mushroom forays present unparalleled opportunities to record macrofungal biodiversity in a place and time. The 2024 NAMA annual foray at the Cispus Center near Randle, Washington was the first mass barcoding activity performed by the NAMA DNA Sequencing Committee (DNAMA). The workflows and methods utilized are presented along with planned improvements. Ultimately, 803 ITS barcodes were generated (83.7% of those attempted) for 513 unique taxa belonging to 209 Genera. Of these, 18 novel putative species-level operational taxonomic units (OTUs) were discovered as well as 28 new distribution reports at state level or above. Methods and suggestions for replicating and improving mass barcoding at forays are discussed.

Minos-mediated transgenesis in the pantry moth
Transposon-mediated transgenesis has been widely used to study gene function in Lepidoptera, with piggyBac being the most commonly employed system. However, because the piggyBac transposase originates from a lepidopteran genome, it raises concerns about endogenous activation, remobilization, and silencing of transgenes , thus questioning its suitability as an optimal tool in Lepidoptera. As an alt...

Integrative analysis of pooled CRISPR screens provide functional insights into AD GWAS risk genes
Emerging research has implicated Alzheimer\'s disease (AD) pathology with dysregulation of many key pathways in microglia, including lipid transport and metabolism, phagocytosis of plaques, and lysosomal function. However, the exact mechanisms underlying these pathways remain poorly understood. Leveraging high-throughput CRISPR screens to understand the interplay between these pathways may enable ...

rbfox1 LoF mutants show disrupted bdnf/trkb2 and crhb/nr3c2 expression and increased cortisol levels during development coupled with signs of allostatic overload in adulthood
Mutations in the RBFOX1 gene are associated with psychiatric disorders but how RBFOX1 influences psychiatric disorder vulnerability remains unclear. Recent studies showed that RBFOX proteins mediate the alternative splicing of PAC1, a critical HPA axis activator. Further, RBFOX1 dysfunction is linked to dysregulation of BDNF/TRKB, a pathway promoting neuroplasticity, neuronal survival, and stress ...

Nucleosome Positioning Shapes Cryptic Antisense Transcription
Maintaining transcriptional fidelity is essential for precise gene regulation and genome stability. Despite this, cryptic antisense transcription, occurring opposite to canonical coding sequences, is a pervasive feature across all domains of life. How such potentially harmful cryptic sites are regulated remains incompletely understood. Here, we show that nucleosome arrays within gene bodies play a...

LIPL-1 and LIPL-2 are TCER-1-regulated Lysosomal Lipases with Distinct Roles in Immunity and Fertility
Reproduction and immunity are fundamental, energy intensive processes that often compete for resources, leading to trade-offs observed across diverse species. Lipid metabolism plays a crucial role in integrating these processes, particularly during stressful conditions such as pathogenic infections. Yet the molecular mechanisms governing this integration remain poorly understood. TCER-1, the C. el...

What can Y-DNA analysis reveal about the surname Hay and the Hay noble lineage of Scotland?
The family name Hay (plus associated spelling variants) is a prominent Anglo-Norman-in-origin surname that has been well-documented as a Scottish noble lineage since the 12th century CE. Their historical significance, linked to the rise of the Anglo-Norman era (1093-1286 CE) in Scotland, and the historical complexities of surname adoption post-Norman conquest of England, justifies the need for a c...

The mini yet mighty stapes: a comparison of ancient DNA yields among ossicles and the petrous bone
The petrous bone is considered the most efficient source of endogenous DNA across skeletal tissues in ancient DNA research as well as in forensic work. Recently, ancient DNA (aDNA) in auditory ossicle bones was shown to be comparably well-preserved as in the petrous, although no attempt was made to distinguish among the three ossicle bones. In this study, we used a total of 114 human ossicle- and ...

Population-scale sequencing resolves correlates and determinants of latent Epstein-Barr Virus infection
Epstein-Barr Virus (EBV) is an endemic herpesvirus implicated in autoimmunity, cancer, and neurological disorders. Though primary infection typically resolves with subclinical symptoms, long-term complications can arise due to immune dysregulation or viral latency, in which EBV DNA is detectable in blood for decades. Despite the ubiquity of this virus, we have an incomplete understanding of the hi...

Huntington's disease LIG1 modifier variant increases ligase fidelity and suppresses somatic CAG repeat expansion
Huntington\'s disease (HD) is a fatal neurodegenerative disorder caused by inheriting an expanded CAG repeat tract in the huntingtin gene (HTT) that further expands in somatic cells over individual\'s lifetime. Genome-wide association studies have provided critical insight into factors that modify the course of disease. These include DNA repair genes that alter the rate of somatic expansion and ot...
