6/20/17 Show feat. Tamas Prileszky on Engineering Fluids and Food Science

Featured image: The late Professor Mainstone with his famous tar drip experiment, which has produced about a drop a decade since 1930. The idea: everything flows.

In this episode, we’re investigating the intersecting worlds of colloids, fluid properties, and food science with Tamás Prileszky, a University of Delaware graduate student in chemical engineering. What governs the diverse behavior of liquids as different as oil and mayonnaise? How can engineers tweak the concoctions they develop? Tamás will share his expertise in droplets, which float around in liquids and drastically affect their properties, and explain what tools and methods scientists use to develop new chemical technologies. Finally, we’ll connect all this with our diets: how do we engineer food, and why is it that we put so many additives in grocery store products?

  • CRISPR, the gene editing technology that’s taking biology by storm, recently made big gains against Huntingdon’s disease in mice.
  • Eclipses (discussed on TVR2C recently) are still a huge opportunity for solar research, as shown by this group from Hawaii studying the temperature of coronal mass ejections.
  • A widely-publicized Tesla crash can be blamed on the driver, not the self-driving car, say new findings by the company.
  • Wild felines became cats and spread all around the ancient world, mostly through two big human-induced migrations. Or at least that’s what scientists can tell from new analyses of ancient cat DNA.
  • Airborne germs survive for a long time after a sneeze or a cough, according to Australian scientists. So long, dreams of cleanliness.

6/13/17 Show feat. Dorit Aviv on Building and Optimizing Buildings + the UN Nuclear Ban Treaty

Featured image: Adlinger Center at Princeton University.

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.

*Tamara Patton and Sébastien Philippe were both past guests on this show. Learn more about Tamara’s research on emergent technologies being used for nuclear disarmament and Sébastien on nuclear arms verification in their interview.

6/6/17 Show feat. Doug Massey on Undocumented Immigration and Border Militarization

This episode, listen to hear Professor of Sociology Doug Massey in an intensely topical conversation: what happens when borders are militarized? What are the impacts of US immigration policy, and how might a border wall affect our country’s population of immigrants? In this interview, we dig into the xenophobia of our politics and media, and see how sociologists view macroscopic trends in migration in the light of baseless misinformation propagated by our news and in our culture.
