  • Founder's Lecture: The Role of Restoration in Preserving Plant Biodiversity

    Zahawi, Rakan; Biology Department and the Charles Albert Read Trust (2022-02-08)
    Dr. Zahawi will present results on a long-term restoration study (>15 years) in southern Costa Rica assessing the effect of different restoration treatments on recovery processes. He will also provide a brief overview of the Charles Darwin Research Station in the Galapagos, and will highlight a few of their core research programs.
  • Microaggressions: What’s the Harm? Examining the Impact of Microaggressions and Racism on Health

    Torres-Harding, Susan; Academic Affairs (2022-02-10)
    Microaggressions are forms of subtle, everyday discrimination that can negatively impact people from disempowered social groups in the US. In her talk, Dr. Torres-Harding will describe and define microaggressions, discuss the cognitive and physiological pathways through which microaggressions may impact health status, and discuss how they may contribute to existing racial health disparities in the US.
  • Genomic Evolution and Adaptation in Africa

    Tishkoff, Sarah; Biology Department and the College of Arts and Sciences (2022-02-10)
    Dr. Tishkoff studies genomic and phenotypic variation in ethnically diverse Africans. She will present research that combines field work, laboratory research, and computational methods to examine African population history, the genetic basis of anthropometric, cardiovascular, and immune related traits, and how humans have adapted to diverse environments and diets.
  • Natural History as an Inspiration for New Technologies - Bio Inspired Design from the Sea

    Summers, Adam; Biology Department and the Charles Albert Read Trust (2022-02-07)
    Using his background in engineering and mathematics, Dr. Summers will discuss the properties of natural materials and their roles in form and function in marine animals.
  • Big Data for Biodiversity

    Pelletier, Tara; Biology Department and ThermoFisher Scientific (2022-02-11)
    Dr. Pelletier will demonstrate how "big data” can be used to understand the historical processes that shape current biodiversity patterns and be used to make predictions for conservation purposes. These data are compiled using computational methods that integrate species occurrences with genetic and/or climatological data on a large scale.
  • The Best Bad Option: Using Science to Guide Public Schools’ Pandemic Response

    Pangallo, Kristin; Chemistry and Physics Department and the Charles Albert Read Trust (2022-02-10)
    Dr. Pangallo will describe how her training as a scientist has helped her navigate the COVID-19 pandemic in her role on the Salem Public Schools Committee.
  • Pteropods as Bioindicators of Climate Change in New England Waters

    Maas, Amy; Biology Department and the College of Arts and Sciences (2022-02-09)
    Human activities, notably the burning of fossil fuels, are causing dramatic changes to the physics and chemistry of the marine environment. One poorly understood or monitored aspect of these changes are the consequences of the changing pH of the marine environment - otherwise known as ocean acidification. Dr. Maas will discuss the effects of ocean acidification on a sensitive calcifying organism in the Gulf of Maine - the shelled pteropod or “sea butterfly” Limacina helicina, and how these data can be used to improve biological monitoring on the East Coast.
  • Investigating FDA-Approved Anti-Tumor Drugs for Effects on Template-Switch Mutagenesis (TSM) in E.coli

    Laranjo, Laura; Addorisio, Sydney; Biology Department and ThermoFisher Scientific (2022-02-11)
    DNA mutations have profound implications for human health. Among the multiple sources of DNA mutations, are secondary structures. Quasipalindrome sequences (QP) are imperfect inverted repeats capable of forming hairpin-like DNA secondary structures. These structures can perturb DNA replication, resulting in mutations, DNA damage, and chromosomal rearrangements. Previous work has shown that these mutations can be caused by the addition of FDA-approved drugs such as 5-azaC, AZT, and ciprofloxacin. Dr. Laranjo and Ms. Addorisio will discuss the results of investigating two additional FDA approved antitumor drugs, CPT-11 and Doxorubicin hydrochloride for their ability to affect template-switch mutagenesis.
  • Climate Change and Food Security - Evidence that Connects Changes in Temperature, Rainfall and Vegetation Dynamics to Nutrition and Human Health Outcomes

    Brown, Molly E.; Geography and Sustainability Department and the Charles Albert Read Trust (2022-02-08)
    Dr. Brown’s talk will address the conceptual frameworks that connect observations of climate variables to individual nutrition outcomes in Africa and Asia. She will describe datasets used to measure climate extremes, explain how food security is defined and share data demonstrating the impact of climate change on food security in children.
  • Enabling a New Era of Ocean Exploration and Discovery with Marine Genomics

    Bodnar, Andrea; Biology Department and the Charles Albert Read Trust (2022-02-09)
    The oceans cover 71% of the Earth’s surface and play a vital role in supporting life on our planet and yet, remain largely unexplored. New genomic technologies provide an unprecedented opportunity to explore the ocean’s vast biodiversity and promote sustainable use of marine resources. Dr. Bodnar’s talk will introduce some of the work being done at the Gloucester Marine Genomics Institute to use genomic technologies to promote healthy and sustainable oceans, and to uncover new discoveries that impact humankind.
  • Tiny Conspiracies: Cell-to-Cell Communication in Bacteria

    Bassler, Bonnie; Biology Department and the College of Arts and Sciences (2022-02-09)
    Bacteria communicate with one another using chemical molecules that they release into the environment. These molecules travel from cell to cell and the bacteria have receptors on their surfaces that allow them to detect and respond to the build-up of the molecules. This process of cell-to-cell communication in bacteria is called “Quorum Sensing” and it allows bacteria to synchronize behavior on a population-wide scale. Dr. Bassler will talk about research into therapies that interrupt quorum sensing.
  • Vegetation and Cloud Cover Shape Semi-Arid Carbonate Landform Development

    Al Abri, Amani; Geological Sciences Department and the Charles Albert Read Trust (2022-02-07)
    Dr. Al Abri’s talk will describe the influence of cloud and vegetation cover on carbonate landforms in southeastern Oman. These phenomena have economic significance as summer monsoon winds deliver heavy fog to the region, supporting plant-life and thereby livestock and agriculture.
