In this episode of These Vibes, Brian subbed in for Stevie (sick and sounded like a screecher monkey) spoke with our resident science historian Ingrid Ockert on her recent article, “Science Television in the Sputnik Age.” Additionally, we welcomed Dr. Julio Herrera-Estrada back on the show to discuss his in-depth research on droughts in North America. All that, and lots of music.
In this episode of These Vibes, Stevie spoke with Dave Seal, a mission planner on the Cassini space probe which spent many years orbiting Saturn. Cassini operated its final maneuver, called the “Grand Finale,” and ended its observing by plunging in to Saturn just last Friday morning at 8am EST. It took a final image and took it’s last bits of data on Saturn’s atmosphere before being destroyed. Listen in to learn about the mission, its development, goals, and discoveries, and learn more about what it’s like to be a mission planner on a NASA space probe.
All that plus great music, and science news from microplastics in our seasalt to the new research on cancer cells.
In this episode of These Vibes, Stevie speaks with neuroscientist Christa Baker about fruit fly mating songs and electric fish — and for each, how she is tracking their neural pathways to learn how their brains undergo the complicated process communication.
Additionally, animal behaviorist Matt Grobis comes on the air to talk about the nitty gritty “devil’s chess match” of doing research — the good and the bad.
This episode of These Vibes was all about language.
In the first part, Stevie spoke with Dr. Kate Riestenberg, linguist and postdoctoral fellow at the Smithsonian Institution and visiting scholar at Truman State University in Missouri, about the varied and far-reaching work of linguists. Then, they took a deep dive in to the topic of endangered languages — how they’re defined, how a language becomes endangered, and why we should care.
In the second portion, Kristin Guest, Bilingual Speech Language Pathologist (SLP), discussed her work in SLP and working with kids in (primarily New York City) public schools. She described the differences between learning, language, and speech disabilities, as well as how you determine if a student has a disability in one of these three categories. Next Kristin gets in to the linguistically and culturally biased assessment practices in schools, and how they should change.

In this installment of These Vibes, Stevie spoke with Alexander Todorov, psychology professor at Princeton and author of the new book “Face Value: The Irresistible Influence of First Impressions,” which just came out in hardcover earlier this month. The book dives in to his research on first impressions — the very human way we make character judgments after only a glance at another person’s face. These impressions are often incorrect, but can affect important decisions we make, like elections and criminality. In this interview we take a deep dive in to the history of the pseudoscience of physiognomy, as well as current research in psychology and the effect of first impressions on elections, criminal justice, and more.

In this installment of These Vibes, graduate researcher in the Computation and Energy track in Princeton University’s School of Architecture, Dorit Aviv, joined us on the mic to discuss her work designing and optimizing buildings. In the image next to the stream you can see Dorit Aviv with her Cool Oculus, discussed in the show.
At the start of the show, Tamara Patton and Sébastien Philippe*, doctoral researchers in mechanical engineering and Science & Global Security, explained the UN Nuclear Ban Treaty, currently in negotiations at the UN as well as the upcoming Women’s March to Ban the Bomb.
In this installment of These Vibes, Professor Edward Felten, director of Princeton’s Center for Information Technology Policy (CITP) and blogger at Freedom to Tinker. Throughout the show we discussed various interactions between policy and technology. Specifically, we dove in to the current state of the technology behind self-driving cars and their prospective impact on several aspects of our society, but specifically jobs. Next, Professor Felten described the use of a form of AI, predictive analytics, in the criminal justice system. Judges in some states use predictive analytics to determine, for example, bail. There is a potential Supreme Court case (it is being considered) on this topic coming up in the next term. And in the last part, Professor Felton gave us a primer on net neutrality and updated us as to the current state of the debate on the topic.
In this installment of TheseVibes, Krupa Jani, MD/PhD researcher in biochemistry, joined us in the studio to share her research in the lab and in the health policy arena. In the first part of the interview, Krupa summed up the American Health Care Act that was recently passed through the House and is currently being considered in the Senate. In parts 2 and 3 we discuss her research in epigenetics and how this is related to cancer.
Epigenetics is the study of gene expression. Every cell in your body contains the same DNA sequence, however which genes are turned on (and thus transcribed in to proteins — or “expressed”) and which are turned off will be different between different types of cells. e.g. your blood cells expresses different genes than your skin cells. In this interview Krupa dives in to what’s happening at the molecular level in this process of gene expression, and how this can go haywire to produce runaway cell replication, which would lead to cancer.
In a past show, Stevie interviewed Professor Bridgett vonHoldt on epigenetics and canine evolution. See the show link for the streaming link and more information.
In this show Stevie interviewed Cameron Ellis, cognitive neuroscience researcher at Princeton University. In the first part of the discussion Cameron explained the different theories of what is/isn’t conscious. Are animals conscious? Light switches? The Internet? How do we know that anything is conscious outside of our own selves?
In part 2, they discussed sensory substitution – this is new, fascinating research showing that we can use our current senses to detect new information, like magnetic fields, and our brain will integrate this in to its neural pathways. This research is extremely promising, and seems likely to be of great importance towards goals of, say, helping a blind person “see.”
In the last section, Cameron answers some great listener questions and delves in to the topic of uploading our consciousness in to computers. Is it still us?
This is the third time Cameron has visited These Vibes. The first and second interviews took place last year, and were all about the scientific and philosophical study, as well as history, of consciousness. These shows are not necessary as pre-requisites to the today’s show, but they are excellent additions. Highly recommend.

In the primary segment of the show, Stevie spoke with Princeton graduate researcher in classics and host of the podcast Ancient Greece Declassified, Lantern Jack (pseudonym), came on the show to discuss ancient cosmologies. Lantern Jack began with ancient Greece, where the geocentric model reigned and where we have the best, early models of the universe (that we know of).
We discussed geocentric and heliocentric models, how the first calculations of the size and distance to the Moon and the Sun were made, and mused about whether there were or weren’t lenses available.
Then, towards the end of the show Lantern Jack told us a bit about the Antikythera mechanism – believed to be an early analogue computer and actually physical cosmological model, recovered from a shipwreck in 1901.
