Throughout history, humans have been on the hunt to discover more about our past ancestors with the intent to reveal more about ourselves and to define what innately makes us human. Although many skeletons and species of Homo have been identified, we have not yet discovered our last common ancestor, and this has been a hot topic of debate. The genus Homo is bookended by Australopithecus afarensis and Homo erectus, the former more ape than human, while the latter was responsible for making stone…

Senior Symposium Summary The first presentation was on Art, Dance, and Music. The research questions aimed to discover the ways that arts can be used for therapy. Creative therapies use new perspectives to treat patients. Each form of art therapy has a different strength. Art therapy is emotional, and it helps people express feelings. It can be used as a form of relaxation or meditation, and as a means of symbolic communication. Many people benefit from art therapy, and materials can be…

hat is a chemical spill? A chemical spill is an uncontrolled, accidental release of a chemical into the environment. What is remediation of chemical spills? The removal of unwanted, hazardous contaminants from an area. There are many methods by which this can be accomplished. Sodium Hydroxide can be fatal to aquatic animals. It is responsible for more than half a million fish in British Columbia in 2005. Phosgene can be released as a gas from household paint removers when exposed to heat. If…

bad as the disaster itself. The Natural Resources Defense Council observed that the Agricultural Street Landfill Superfund Site had “visible leachate emerging from the site and spreading across the street and onto a local senior center’s property. Sediment testing at this site found contamination as much as 20 times higher than the EPA soil cleanup standards…” (37). The “visible leachate” shows how serious the issue was, because its intensity was able to travel across an entire street, not a…

Virginia’s coast is seen as the highlight of the state. The only gem that should be protected at all cost. So we pour millions of dollars to beautify the beach and bring in more people. We do this because in the end more people means more money. This mentality has made us blind to the fact that we have other wetlands in far greater danger than the beach. Marshes and swamps are just as valuable in what they offer the community. Factoring in the knowledge makes wetlands worth saving, not for the…

I am a junior at Bowdoin College majoring in Earth and Oceanographic Science (EOS). In the 2018 spring semester I will be studying abroad with SEA Semester and completing a semester-long research project about carbon cycling in the sub-Antarctic Ocean. Although my major, earth and oceanographic science, has exposed me to plate tectonics, sedimentary systems, and biogeochemical cycling, I have focused my major mostly on ocean systems. Within oceanography I am most interested in marine nutrient…

The (UMESC) Scientists have developed a controlled-Release formulation of Bayluscide this is designed to kill sea lamprey in the bottom sediments where they reside without impacting other non targeted organisms. US and Canadian governments are spending $20 million per annum to execute an integrated pest management program that kills larvae of Sea Lamprey with targeted pesticides. In…

Heidegger sought to radicalize the traditional understanding of what it means to be human and the transform the ‘common sense’ approach held by the tradition by reawakening the question of the meaning of being; however, he arrived too early. Even though his unfinished edifice was successfully nailed on the door of Cartesian tradition long ago; the discussion fell, and is still falling, upon deaf ears. This split with the tradition led him to a disagreement with his old master Edmund Husserl…

detail on how hard it was to work for 17 days straight in the scorching hot South Dakota summer. He described how they had to use tools like picks, shovels, jackhammers, and eventually a skid loader to remove most of the sediment surrounding Sue. After most of the surrounding sediment was removed, Larson and his team had to use finer handheld tools to uncover the bones. This showed that paleontologists work astonishingly hard to uncover their fossils. The story of Sue is greatly significant to…

works by comparing isotopes of carbon and their half-lives. This is an especially accurate method because it is unfazed by chemical, temperature, and physical changes so the timing will be correct no matter what. Another form of dating is using soil, sediment, or peat build-up. Since the build-up of these materials occurs in chronological order if undisturbed, it can show a timeline of objects and events. It can also show environmental events like fires to give an idea of what the climate might…
