Ssippin' Science Oxford Science Cafe

In this episode, Madi Wayt sumarizes highlights from the October 2019 Oxford Science Cafe talk by Dr. James Cizdziel from the UM department of chemistry and biochemistry.

Plastics are everywhere! We are living in an age of plastics, much like  the Bronze and Iron Ages. Whereas plastics are cheap and useful, they  are also carelessly   discarded and mismanaged. Unfortunately, this has resulted in widespread plastic pollution, including the infamous ocean  garbage patches. Worse, plastics degrade by UV-radiation, microorganisms, and mechanical action (e.g. waves), yielding smaller and smaller particles called micro- and nano-plastics. These small plastic particles accumulate in the food chain and have even been detected in rain! Dr. Cizdziel introduces microplastics as an emerging global pollutant, discuss its sources and impacts. What can we do to save our oceans from this invisible threat?

In this episode, we interview Dr. Josh Gladden, Vice Chancellor of Research at the University of Mississippi who gave the first-ever Oxford Science Cafe in October 2011.

The Oxford Science Cafe was founded in October 2011 by Dr. Marco Cavaglia, then Professor of Physics at the University of Mississippi. 10 years later, he tells the story of its inception: where he got the idea and inspiration, how he conceptualized it in Oxford, MS, and how the community has engaged and benefitted from the regular monthly conversations about science over a decade.

The Oxford Science Cafe turns 10 this month! Starting from October 2011, it has presented monthly talks and conversations on science for the community in Oxford MS. To celebrate, we present season 2 of the Ssippin' Science podcast featuring interviews with past speakers at the cafe, and more!



Meet the new production team of graduate students from the University of Mississippi: Sumeet Kulkarni, Lorena Magana Zertuche, Morgan Perkins, Subhayu Bagchi, and Madi Wayt.

Archaeologists reconstruct the past in multiple ways, using novel scientific techniques, historic records, oral traditions, and artifacts. Lexi O’Donnell and Carolyn Freiwald talk about their research on ancient migration in northern New Mexico and today’s Mexico City 800 years ago using the biological and chemical differences in human teeth. Who were migrants in Tlalnepantla, Mexico?  What happened to the Gallina people in northern New Mexico when their homes were abandoned? Dental morphology and isotopic analysis are key forensic techniques that answer questions posed by historical records and oral traditions.



Edit: At 5:30, there do exist other stone towers in the Southwest, but outside the region where this research was conducted.

In the build-up to the launch of Perseverance: the Mars 2020 rover, we talk with Dr. Janice Bishop, Chair of the Astrobiology group at the SETI Institute. Her research involves using spectroscopy to shine a light (of multiple wavelengths) on the molecular structure of different minerals found on Mars. Listen to how Perseverance is going to be instrumental in expanding this avenue of research and enjoy stories about how the rover landing site was selected.
