Special Episode: Brain Preservation and Abolishing Death
An interview with Ariel Zeleznikow-Johnston, author of the book 'The Future Loves You: How and Why We Should Abolish Death'. We begin by discussing how best to define death, focusing on the idea of death as the permanent disruption of psychological identity, and how such identity is constituted by our personality, desires, and memories. We then consider the science of brain preservation, including the recently-developed technique of Aldehyde-Stabilized Cryopreservation, and how it could be used to indefinitely preserve the brain structure that encodes or personal identity. Ariel argues that such a preserved brain could potentially be used to construct a digital simulation of our brains, essentially allowing us to survive the biological death of our bodies. We conclude by considering some potential challenges of implementign such a technology, and whether it would achieve widespread social acceptance.

Episode 148: Control of Gene Expression
An introduction to the processes by which cells control which genes are expressed. We begin with an overview of why genetic regulation is necessary and the key stages where such regulation occurs, including key concepts such as transcription factors and DNA binding domains. We then discuss prokaryotic gene regulation, focusing on the lac operon in E. coli. We then expand the discussion to cover the various mechanisms of eukaryotic gene regulation, including chromatic remodelling, transcriptional regulation, post-transcriptional regulation, RNA editing, and micro RNAs. Recommended pre-listening is Episodes 34-35: DNA Structure and Function, and Episode 118: Cell Signalling.

Episode 147: Genetic Mutation and Repair
Here we survey of the causes and consequences of genetic mutation, including a discussion of mechanisms of endogenous and induced mutations, rates of mutation, types of single nucleotide mutations, and the phenotypic effects of mutation. We also discuss various mechanisms for detecting and repairing genetic mutations, including base excision repair, DNA mismatch repair, nucleotide excision repair, double strand break repair. We conclude with an examination of large-scale chromosomal changes, including deletions, duplications, inversions, and translocations, unequal crossing over, with a brief look at polypoidy in plants and aneuploidy in humans. Recommended pre-listening is Episodes 34 and 35: DNA Structure and Function, and Episode 44: Cell Division.

Episode 146: Mendelian Genetics and Inheritance
An introduction to classical Mendelian genetics, in which we discuss Mendel's experiments with peas and the laws of heredity that he discovered, including inheritance of one allele from each parent, the law of dominance, and the law of independent segregation. We then consider more complex cases of genetic inheritance, including sex-linked traits, incomplete dominance, codominance, and epistasis. The episode concludes with a discussion of quantitative traits determined by many genes, including how genetic variation is described, how sources of variance are identified using genome wide association studies, and the conceptual issues with defining heredity and separating the effects of genes from those of environment.

Episode 145: Relativity and Black Holes
Continuing our series on General Relativity, we discuss the derivation of the Schwarzschild metric as a vacuum solution to Einstein's Field Equations, and analyse the physical meaning of this solution, including the properties of the singularity, event horizon, and effects of time dilation and length compression. We then consider how solutions like the Schwarzschild metric yield testable predictions such as gravitational lensing and graviational redshift, which serve as important evidence in support of General Relativity. We conclude with a discussion about some of the more exotic aspects of black holes, including Hawking radiation, the no hair theorem, and the black hole information loss paradox. Recommended pre-listening is Episode 136: Introduction to General Relativity.
