The Cost Of Affordable Food, Candice L. Cobuzzi
The Cost Of Affordable Food, Candice L. Cobuzzi
SURGE
When someone puts a piece of food in front of me, I don’t just see a piece of food.
Instead, I see an innocent cow being cornered by a forklift and slaughtered, its limp, moist tissue hung on a long conveyer belt with hundreds of others.
I see hundreds of chemically-injected chickens packed into a dark barn with no hope of seeing sunlight in their lifetime.
I see immigrants pulled from their houses like criminals, taken away from the lives they’ve spent years building for themselves and their families, working for the same food company that courted them into the …

Our Gendered Food Chain, Jasmine T. Colahan
SURGE
Over the past four decades, the number of women-operated farms has nearly doubled. Including both primary and secondary operators, one million women make up thirty percent of all U.S. farmers.
Headlines such as “Females Take the Reins,” “Meet the New face of Agriculture,” “Old McDonald Might Be a Lady” demonstrate this gender shift. And, it is true in my life too. As I worked on the Painted Turtle Farm this summer, the majority of my role models, co-workers, and mentors working in agriculture, whether rural or urban, were primarily women. [excerpt]

The Deletion Of The Bre1 Gene In Aspergillus Nidulans Impairs Mitotic Growth, Meiosis, And Dna Damage Repair, Andrea J. Sitton, Steven W. James
The Deletion Of The Bre1 Gene In Aspergillus Nidulans Impairs Mitotic Growth, Meiosis, And Dna Damage Repair, Andrea J. Sitton, Steven W. James

Bre1 is a homotetrameric E3 ubiquitin-protein ligase that heterodimerizes with Rad6, an E2 ubiquitin-conjugating enzyme, in order to ubiquitinate lysine 123 in Aspergillus nidulans. This post-translational modification promotes methylation of lysines 4 and 79 on histone H3, which are required for certain damage repair pathways and for both optimal mitotic cell growth and meiosis [1-3, 12]. ΔBre1 mutants were generated by exposing protoplasts from strains auxotrophic for pyridoxine to a three-way fusion construct made from the Bre1 5’ and 3’ flanking regions and the Aspergillus fumigatus pyroA gene, which served as a selectable marker. Molecular diagnosis was confirmed via trans-locus …
Effects Of Prior Acute Exercise On Circulating Cytokine Concentration Responses To A High-Fat Meal, Josef Brandauer, Rian Q. Landers-Ramos, Nathan T. Jenkins, Espen E. Spangenburg, James M. Hagberg, Steven J. Prior
Effects Of Prior Acute Exercise On Circulating Cytokine Concentration Responses To A High-Fat Meal, Josef Brandauer, Rian Q. Landers-Ramos, Nathan T. Jenkins, Espen E. Spangenburg, James M. Hagberg, Steven J. Prior

High-fat meal consumption alters the circulating cytokine profile and contributes to cardiometabolic diseases. A prior bout of exercise can ameliorate the triglyceride response to a high-fat meal, but the interactive effects of exercise and high-fat meals on cytokines that mediate cardiometabolic risk are not fully understood. We investigated the effects of prior exercise on the responses of circulating tumor necrosis factor-a (TNF-a), interleukin-6 (IL-6), IL-8, leptin, retinol-binding protein 4 (RBP4), vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), placental growth factor (PlGF), and soluble fms-like tyrosine kinase-1 (sFlt-1) to a high-fat meal. Ten healthy men were studied before …

Milking The System: Do Poor People Deserve Fresh Food?, Melanie M. Meisenheimer
SURGE
Poor Americans are all lazy, selfish people who must first prove their worth as human beings if they want to be able to feed their children.
It sounds harsh, stereotypical, and judgmental when you put it like that, and few people would feel comfortable saying that exact phrase. However, it’s a perception of poverty in America that I’ve found still has a strong grip on our way of thinking. [excerpt]

The salamander is the only tetrapod that regenerates complex body structures throughout life. Deciphering the underlying molecular processes of regeneration is fundamental for regenerative medicine and developmental biology, but the model organism had limited tools for molecular analysis. We describe a comprehensive set of germline transgenic strains in the laboratory-bred salamander Ambystoma mexicanum(axolotl) that open up the cellular and molecular genetic dissection of regeneration. We demonstrate tissue-dependent control of gene expression in nerve, Schwann cells, oligodendrocytes, muscle, epidermis, and cartilage. Furthermore, we demonstrate the use of tamoxifen-induced Cre/loxP-mediated recombination to indelibly mark different cell types. Finally, we inducibly …

The upland sandpiper (Bartramia Longuardia) has experienced a steep population decline in the northeastern U.S. since the mid-20th Century. In Pennsylvania it was found in less than 0.5% of atlas blocks during the Second Atlas of Breeding Birds in Pennsylvania project (2nd PBBA; 2004-09) and breeding was confirmed at only two locations. Due to continued declines and a small population size, the upland sandpiper was listed as PA endangered in 2012. During May 2012 the areas around 15 2nd PBBA upland sandpiper sightings were resurveyed by Gettysburg College students and volunteer birdwatchers. The aim was …

Much scholarship points to how ecological concerns are never far from Indigenous struggles for political sovereignty and public participation. In this paper we turn to the Indigenous film festival as a relatively understudied yet rich site to explore such ecological concerns. Specifically, we highlight the ImagineNATIVE 2012 film festival based in Toronto, Canada.
