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.
A chill show — just music and science news. Unfortunately we were switched to webstream-only about 40 minutes in (for a lacrosse game), and neglected to record the rest of the show. Still! Here’s the science news we discussed. Enjoy:

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.
Much of the scientific study of memory has focused on two vital human test subjects: Henry Molaison (“HM”) and Lonnie Sue Johnson. HM had his memory stolen from him in an experimental surgery in the 1950s and Princeton local, Lonni Sue, can no longer form new recollections due to an encephalitis infection that laid waste to her hippocampus. Lonnie Sue and HM have been permanently stuck in the present, but through their loss, the science of how we process, recall, and store memories has flourished.
In this on-stage version of These Vibes Are Too Cosmic, hosts Stevie Bergman and Brian Kraus interview Princeton University professors Sabine Kastner (neuroscience) and Michael Lemonick (opinion editor at Scientific American). Professor Lemonick’s recently released book, The Perpetual Now: A Story of Amnesia, Memory, and Love, delves in to the rich life of Lonnie Sue Johnson and Professor Kastner’s scientific expertise – memory.
Musical accompaniment, and half the fun, will be provided by the Princeton Laptop Orchestra (PLOrk). For the event they’ve composed a special symphony of neurons that will punctuate the conversation. Expect harmonies rife with PLOrk’s unique sense of discord, drama, and entertainment.
Join us on Friday, February 24th, 2017 at 7:30pm at the beautiful Taplin Auditorium in Fine Hall, right on Princeton University campus. Refreshments, science, and music will all be provided.
Short show due to the new 6-8pm time slot and a sports interruption. We give an update on science events in the area and share some science news, as well as some new music, as always.
First results from the NASA twin study with astronaut Scott Kelly and his brother (who stayed on Earth), Mark. Right now the analysis of the data is in the early stages, but there are potentially interesting results with telomeres – the ends of the DNA chromosome whose diminishment tends to correlate with aging.
Brian presented an interesting study about differences in gene behavior between genders and implications for disease susceptibility.
In this week’s installment of These Vibes, we spoke with Tamara Patton, doctoral researcher at the Woodrow Wilson School at Princeton and in the Nuclear Futures Lab, on her work using emergent technologies, specifically virtual reality, in nuclear arms control. She also delves in to the prospect of nuclear proliferation and arms control under the Trump presidency and the upcoming nuclear weapon ban treaty taking place this March at the UN.

This show is a little different. The plan was to have author and professor Patrick Phillips on for the first hour, alas there had to be a rescheduling at the last minute. Instead we will be interviewing Patrick Phillips on his book Blood at the Root at the end of next month (January 2017), so stay tuned.
Hour 1: Lots of music and some science news, including self-driving cars. Hour 2:Thomas Macrina on machine learning, neuroscience, and mapping our brain – our connectome. Hour 3: Kasey Wagoner, lecturer in physics at Princeton, on the bedrock scientific principle called the Equivalence Principle. In this discussion, Kasey tells us about the history, the principle’s importance, and current tests.
