In this episode of Earth News Interviews, we speak with grad student Erkan Gun and professor Russ Pysklywec about the mechanisms that drive continental movements! Note: This interview was recorded back June 2021. Primary source discussed: Pre-collisional extension of microcontinental terranes by a subduction pulley ..read more

Happy International Women's Day! In this special episode of ENI, we have a roundtable style discussion on the topic of Diversity, Equity, and Inclusion (DEI) in the Earth Sciences. Joining Kathryn in this episode, we have Assistant Professor Tasca Santimano and PhD students Sophia Zamaria and David Aceituno-Caicedo.   Primary readings discussed: - Gender representation cues labels of hard and soft sciences - No progress on diversity in 40 years ..read more

In this episode of ENI, we talk to the University of Toronto's new assistant professor, Andrei Swidinski about how mineral exploration is done using geophysics - magnetotellurics and passive seismic!   Primary readings discussed: Application of deep-penetrating geophysical methods to mineral exploration: Examples from Western Australia ..read more

Welcome back to a new year of Earth News Interviews!   In this episode, Dean, Winnie, Kathryn, and Tina each discuss their favorite earth sciences paper from 2021. Primary reading discussed: - Using phylogenies to detect a major extinction event in the Oligocene of Africa - Clues from soured milk reveal how gold veins form - Diversity, equity, and inclusion: Tackling under-representation and recognition of talents in geochemistry and cosmochemistry - Accidental synthesis of a previously unknown quasicrystal in the first atomic bomb test   ..read more

In this episode, we interview Andrew Parmenter, a geologist working for the Nuclear Waste Management Organization (NWMO), a not-for-profit organization tasked with the safe, long-term storage of Canada’s used nuclear fuel in a manner that protects people and the environment for generations to come. Nuclear waste is a reality our generation has been tasked with storing in a safe way after being passed on from previous generations. We touch upon the key features of long-term nuclear waste repositories, building strong relationships with local Indigenous communities, and what the role of a geolog ..read more

We typically expect physical phenomena to follow certain rules: an apple falls from a tree under the influence of gravity, a skater will eventually slow down from the friction between their skates and the ice, a star spins in a similar direction as the planets in its solar system... Here's the interesting bit, the last one doesn't always hold true. In fact, astrophysicists theorized that there are solar systems in outer space that don't follow this rule. And in 2019, scientists measured this counterintuitive phenomenon in a solar system almost 900 light-years away called K2-290. Their findings ..read more

Many Earth Sciences Departments have been recording low enrollment numbers for the last decade. This field has been known to ride the industry wave; high enrollment when the oil, petroleum, and mineral resource industry is booming, low when it's not. This time, the ebb and flow of markets aren't the cause. General public mistrust of the industry, lack of diversity, and reliance on courses that no longer seem to fit with modern problems are just a few reasons Assistant Professor Erik Klemetti, a volcanologist and science communicator at Denison University cites in his Discover Magazine art ..read more

The first exoplanet was discovered in 1992 by Aleksander Wolszczan and Dale Frail. Less than 30 years after this initial discovery that won the Nobel Prize in Physics, more than 4000 exoplanets have been confirmed (NASA). These planets, while unique, have some similarities in mass and size, and potentially other features, to Earth. While we aren't able to take a sample from the surface of these planets, that doesn't mean we're limited to simply guessing at their composition. Associate Professor of Physics and Astrophysics at the University of Toronto Scarborough, Dr. Diana Valencia walks us th ..read more

With natural disasters become more frequent and damaging, how can we accurately access who's at risk without updated information and predictions? The answer is we can't. That's why accurate risk and hazard mapping is essential for both private homeowners and all levels of government that have a public responsibility to mitigate the adverse after-effects of disasters. In this episode we talk to Professor Joseph Desloges of the Geography and Planning Department at the University of Toronto. He specializes in the influence of rivers, glaciers and humans on landform development, and has a particul ..read more

Imagine if you lived in a world where some humans evolved the ability to fly, use one hundred percent of their brainpower, or the ability to reproduce at twice the normal rate. These evolved humans would certainly have an evolutionary advantage over the rest of us, and likely outcompete us in the long-term. What if a similar situation happened around 541 million years ago? Around this time, in the late Neoproterozoic, the Ediacaran biota, mostly filter-feeding and immobile organisms, faced the threat of extinction from their more agile, burrowing, and mobile competitors that evolved during the ..read more
