Another month, another update about the awesome research coming out of Sonoma State.
Costa, D. P., Holser, R. R., Keates, T. R., Adachi, T., Beltran, R. S., Champagne, C. D., Crocker, D. E., Favilla, A. B., Fowler, M. A., Gallo-Reynoso, J. P., Goetsch, C., Hassrick, J. L., Hückstädt, L. A., Kendall-Bar, J. M., Kienle, S. S., Kuhn, C. E., Maresh, J. L., Maxwell, S. M., McDonald, B. I., & McHuron, E. A. (2024). Two decades of three-dimensional movement data from adult female northern elephant seals. Scientific Data, 11(1).
Abstract: Northern elephant seals (Mirounga angustirostris) have been integral to the development and progress of biologging technology and movement data analysis, which continue to improve our understanding of this and other species. Adult female elephant seals at Año Nuevo Reserve and other colonies along the west coast of North America were tracked annually from 2004 to 2020, resulting in a total of 653 instrument deployments. This paper outlines the compilation and curation process of these high-resolution diving and location data, now accessible in two Dryad repositories. The code used for data processing alongside the corresponding workflow is available through GitHub and Zenodo. This data set represents 3,844,927 dives and 596,815 locations collected from 475 individual seals with 178 repeat samplings over 17 years. We anticipate that these data will stimulate further analysis and investigation into elephant seal biology and aid in developing new analytical approaches for large marine predators.
Cai, P., Casas, C. J., Quintero Plancarte, G., Mikawa, T., & Hua, L. L. (2025). Ipsilateral restriction of chromosome movement along a centrosome, and apical-basal axis during the cell cycle. Chromosome Research, 33(1).
Abstract: Little is known about how distance between homologous chromosomes are controlled during the cell cycle. Here, we show that the distribution of centromere components display two discrete clusters placed to either side of the centrosome and apical/basal axis from prophase to G1 interphase. 4-Dimensional live cell imaging analysis of centromere and centrosome tracking reveals that centromeres oscillate largely within one cluster, but do not cross over to the other cluster. We propose a model of an axis-dependent ipsilateral restriction of chromosome oscillations throughout mitosis.
Senger, K., Shephard, G., Ammerlaan, F., Anfinson, O., Audet, P., Coakley, B., Ershova, V., Faleide, J. I., Grundvåg, S.-A., Horota, R. K., Iyer, K., Janocha, J., Jones, M., Minakov, A., Odlum, M., Sartell, A., Schaeffer, A., Stockli, D., Vander Kloet, M. A., & Gaina, C. (2024). Arctic Tectonics and Volcanism: a multi-scale, multi-disciplinary educational approach. Geoscience Communication, 7(4), 267–295.
Abstract: Geologically, the Arctic is one of the least-explored regions of Earth. Obtaining data in the high Arctic is logistically, economically, and environmentally expensive, but the township of Longyearbyen (population of 2617 as of 2024) at 78° N represents a relatively easily accessible gateway to Arctic geology and is home to The University Centre in Svalbard (UNIS). These unique factors provide a foundation from which to teach and explore Arctic geology via the classroom, the laboratory, and the field. This article outlines a course taught a UNIS and student perspectives of the course to illustrate that multi-disciplinary, multi-lecturer field-and-classroom teaching is efficient and increases student motivation to explore Arctic science.
Rognlie, D., Anderson, E., & Burke, M. (2024). Erotic Ambivalence in Beauvoir’s Student Diaries. Simone de Beauvoir Studies, 35(1–2), 242–264.
Abstract: This article challenges Margaret E. Simons's claim that Sartre forced himself on Beauvoir on October 15, 1929. We argue that Diary of a Philosophy Student: Volume 3, 1926-30 depicts the young Beauvoir struggling with conflicting feelings about marriage, sexual desire, and gender roles. Highlighting early reflections on "the woman in love,"we suggest that Beauvoir's diary discloses gendered harm but not sexual violation. We name this harm erotic ambivalence and find it central to The Second Sex.
Das, M., Anfinson, O., Rowe, C., & Schroeder, N. (2025). Age, sedimentology, and deformational history of the Mesozoic Franciscan accretionary complex, Angel Island, California, USA. Geological Society of America Bulletin., 137(1–2), 351–373.
The Franciscan Complex represents the forearc accretionary wedge that formed during late Mesozoic–Cenozoic subduction in California, USA, and preserves detailed records of long-lived subduction and exhumation of high-pressure, low-temperature rocks. As one of the world’s largest exposed subduction complexes, it records the evolution of subduction dynamics that correspond to the tectonic development of the western USA. We present new mapping, lithologic descriptions, and detrital zircon U-Pb geochronology to propose a new lithostratigraphy for Angel Island consisting of seven structurally juxtaposed units ranging from sub-metamorphic to low blueschist. These results offer the first high-resolution detrital zircon U-Pb geochronologic dataset from the Franciscan Complex that allows definition of the diversity of age and provenance within a previously defined regional unit, which should be considered in future work attempting regional correlations with regional sample distribution.
