A landslide into an Alaskan fjord displaced enough water to trigger the second largest recorded tsunami with a run up of 481 meters up the opposite shore in August 2025. This time Dr. Jeffrey Zurek sits down with University of Calgary geoscientist Dr. Dan Sugar to investigate the geophysical processes behind natural hazards, megatsunamis, glacial debuttressing, and the devastating rock-and-ice avalanche in Nepal.

Discover how advanced remote sensing tools like InSAR, NISAR, and LiDAR are revolutionizing geological hazard mapping, why climate-driven glacial retreat is destabilizing mountain slopes across high latitudes, and what it feels like for researchers tracking catastrophic geohazards in real time. We explore the non-linear pathways of scientific careers, the emotional toll of studying active disasters, and the socioeconomic determinants that dictate global hazard preparedness and community resilience.

Topics Covered

The Physics of Megatsunamis: Understanding extreme water displacement, wave run-ups, and seiches in narrow fjords

Glacial Debuttressing: How the rapid retreat of glacial ice removes critical structural support from steep mountain slopes

Remote Sensing Innovations: Leveraging InSAR, NISAR, and LiDAR data to map precursory deformation before slope failure

Whimsical Wavelengths: Deep-dive conversations where a working scientist unpacks how we know what we know, one paper, one idea, or whimsical detour at a time. Hosted by Dr. Jeffrey Zurek (P.Geo)

Hey! I'd love to hear your thoughts, send me a voice note.

In this episode of Whimsical Wavelengths, Dr. Jeffrey Zurek sits down with Dr. Katherine Borden, a professor at Northwestern University's Feinberg School of Medicine, to explore the ancient and vital protein eIF4E (or 4E). Long misunderstood as a simple rate-limiting factor in protein synthesis, 4E acts as a master regulator of RNA processing, transport, and translation. Dr. Borden shares the serendipitous discovery of finding 4E in the cell nucleus, how cancer cells hijack this machinery to drive aggressive disease states like acute myeloid leukemia (AML), and the ongoing journey of translating basic science into clinical trials using repurposed antivirals.

Sub-Themes and Highlights

The Research Process and Serendipity: How a control experiment looking for viral interactions led to a major paradigm shift in understanding 4E’s nuclear localization.

Social Impacts and Translational Health: Exploring the challenges of drug resistance, glucuronidation, and the human side of clinical trials for heavily pretreated patients.

Community and Collaboration: Highlighting the Canadian Sciences Speakers Network (CSSN) as a vital tool for connecting researchers, media, and the public beyond traditional word-of-mouth networks.

Season 3 kicks off by flooding the auditory landscape with a deep dive into glacier outburst floods. This episode explores the Missoula Floods, the historical war of ideas between uniformitarianism and catastrophism, and the lonely scientific journey J. Harlen Bretz. Along the way, we examine how intellectual paradigms shift, how ice dams physically fail under immense hydrostatic pressure, and what these ancient cataclysms mean for how we understand geoscience history.

Key Themes & Sub-Themes

The Research Process & Scientific Resistance: Tracing how radical ideas outrun prevailing frameworks, from Aristotle and medieval European dogma to Shen Kuo, Ibn Sina, and the hostile academic mockery faced by J. Harlen Bretz in the 1920s.

Geological Mechanics & Hazards: Unpacking the science of glacial outburst floods, the immense scale of Glacial Lake Missoula, ice rheology, and the mechanics of hydrostatic uplift that cause massive ice dams to catastrophically self-destruct.

Environmental Impacts: Examining the landscape-scale destruction of the Channeled Scablands, the stark contrast between soil-starved basalt deserts and rich agricultural valleys, and the broader lessons of how scientific consensus evolves over generations.
