In this episode of These Vibes, Stevie discusses measuring neutrino that were produced just one second after the Big Bang singularity in our early universe with Princeton University professor and high energy physicist, Chris Tully. In the interview, Professor Tully explains what a neutrino is, why they’re so difficult to measure, and why we should have a bath of neutrinos sitting at just a couple of degrees above absolute zero all around us today. Then, he tells us about the early universe when that bath of neutrinos, called the Cosmic Neutrino Background, were produced, and how he plans to measure them with his instrument PTOLEMY (Princeton Tritium Observatory for Light, Early-universe, Massive-neutrino Yield – currently in the prototype stage).
- “Mystery of Greek Amphitheater’s Amazing Sound Finally Solved.” An older piece of news that describes research discovering how a 4th century BC theater in Greece could seat 14,000 people such that even those in the back row of the architectural masterpiece could hear actors and musicians — unamplified.
- “First Human Embryos Edited in the US.” A piece in MIT Technology Review describes the first known attempt at creating genetically modified human embryos in the United States. It has been carried out by a team of researchers in Portland, Oregon led by Shoukhrat Mitalipov of Oregon Health and Science University. The procedure involved changing the DNA of a large number of one-cell embryos with the gene-editing technique CRISPR.
