Episode 33: Heidi Nowakowski - The First Semester of Medical School
Pre-med is a popular major at LSU, but how do you prepare for medical school and what’s it like once you are there? We are highlighting former LSU College of Science students in different stages of their medical careers—from just getting accepted to the final stretches—to learn what it takes to succeed in medical school. This episode is featuring Heidi Nowakowski, LSU Spring 2019 College of Science grad. Heidi is currently in her second year in med school at LSU New Orleans, but we caught her in the middle of her first semester. She shares her insights into what it takes to get into medical school, the first semester transition struggles, and her advice on how to cope with med school stress.
Episode 32: Anna Hiller - Hybridization in Andean Nectar Bandits
In nature hybrid zones are where two species or varieties meet and cross fertilize, such as the classic donkey plus horse equals mule. A single hybrid zone is scientifically important for understanding how species diverge. So imagine the excitement of finding not just one, but two hybrid zones in the Andes of South America. And even cooler the hybrid zone is the home of a special type of bird, flowerpiercers, who steal nectar from plants using their pirate-hooked bills. Anna Hiller, LSU Museum of Natural Science Ph.D. candidate, tells us what hybrid zones are, what we can learn from them and how she is using the flower piercers as her model. She also shares adventures from her previous expeditions and how her passion to include women in science is informing her upcoming field trips to Peru and Bolivia.
Episode 31: Phil Bart - The Past, Present, and Future of Antarctic Ice Sheets
At this very moment, the ice sheets covering and surrounding Antarctica are dynamic, moving and receding in response to temperature and other factors. Some of the changes are abrupt and quite apparent, like calving events where large chunks of ice break off of glaciers and plunge into the ocean. Others are more subtle because the movement of the ice is occurring slowly, like it has done for over thousands of years. Dr. Phil Bart, LSU College of Science Geology & Geophysics professor, invites us to learn about the evolution of Antarctic ice sheets and how he investigates the movement of ice sheets and ice rises over geologic time to aid in predicting their future behavior.

We learn what a typical day looks like for an Outreach Specialist, how to develop activities for public events and spaces, the curves in Valerie’s science career that led her to the museum, and how she hopes to inspire the next generation of scientists.
Episode 28: Rebecca Christofferson - Pesky Blood Sucker & the Arboviruses They Carry
Mosquitoes can cause more than an itchy welt. They are vectors of arboviruses. But what is an arbovirus? Dr. Rebecca Christofferson, Assistant Professor of Pathobiological Sciences from the School of Veterinary Medicine, presented her research on the transmission of these harmful viruses and how we can protect ourselves from them during LSU’s Science Cafe Talk in July 2017. Following her presentation, we continued discussing all things mosquitoes and dove into a range of topics including vector borne disease spread, the systematic spraying of Deet, mosquito trivia, and the vulnerability of different countries to these rapid outbreaks.

We explore these connections and how the stories of the past can help us prepare for the future.
Episode 24: Hayley Johnson & Sarah Simms - Japanese Internment Camps in Louisiana
Did you know that over 1,000 Japanese men were interned in Louisiana during World War II? Hayley Johnson and Sarah Simms, passionate librarians from LSU Libraries, explore this buried history in our own backyard.

Episode 21: Heather McKillop - Preserving Mayan Artifacts with 3D Printing
How do you discover ancient Maya artifacts buried underwater? And what do you do with the artifacts once you discover them? Heather McKillop, Thomas & Lillian Landrum Alumni Professor in the Department of Geography and Anthropology, presented her research on ancient Mayan civilizations during LSU’s Science Cafe in September 2017. We later sat down with Dr. McKillop, where she shared how her team has been able to study submerged Mayan villages, excavate artifacts and preserve those artifacts through 3D printing so we can better understand the livelihood of the Maya.
Learn more about what is happening with Dr. McKillop on Twitter @underwatermaya or by heading over to underwatermaya.com to catch the latest adventures in science from the DIVA lab! You can also watch Dr. McKillop's LSU Science Cafe Talk and see the incredible artifacts and locations where she conducts her research.
Episode 20: Whitney Kroschel - Flooding on the Floodplains
Floodplains. The term conjures up images of iconic Louisiana swamps- cypress trees, alligators, and areas inundated with water. But what a floodplain really is, is a wetland ecosystem which periodically experiences pulses of floodwaters, bringing nutrients and sediment to the land. While these cyclic events can be beneficial to wetland communities, continuous flooding may be deleterious to the native species. Whitney Kroschel, Ph.D. candidate in the School of Renewable Natural Resources in the College of Agriculture takes us on an ecological journey through the floodplains to give us a perspective of how flooding is influencing Louisiana cypress swamps and the inhabitants within.
Episode 19: Malinda Sutor - Big Impact Tiny Creatures
Plankton provide the single largest source of oxygen and carbon sequestration on this planet all while nourishing the largest mammal on Earth, the blue whale. With the rise in temperature and acidity in the ocean an urgent question emerges; how will the environmental changes affect the plankton’s ability to maintain these global processes and provide the foundation of the world’s food web? Join us in our conversation with Dr. Malinda Sutor, from the Department of Oceanography and Coastal Sciences in the College of Coast & Environment, as we cover a range of topics including the challenges of quantifying zooplankton to her research into this puzzling question to the importance of quantifying these organisms from a national defense perspective.

We catch up with Prosanta in his office following the announcement of being named TED Senior Fellow to learn more about his TED experiences, recent research adventures, and advice for for sharing your science.
Episode 5: Mark Benfield - The River of Plastic
We are surrounded by single-use plastic. We dispose of plastic bags, water bottles, and coffee stirrers quickly after their uses, yet their existence remains. These persistent plastics find their way into our waterways, leaching toxic chemicals and breaking down into smaller and smaller microscopic pieces, eventually corrupting the entire food web. Dr. Mark Benfield with the Department of Oceanography and Coastal Sciences in the College of Coast & Environment shares his recent research on microplastics in the Mississippi River, which may soon be known as the river of plastic.
