Episode notes
Lichen Discovery in Nunavik
- Normand Voyer's team investigated Stedokolon-Pashkelle, a lichen from Umiujaq, Nunavik.
- They discovered two unique natural substances, highlighting the chemical diversity of northern organisms.
Antimalarial from a Fungus
- A fungus, Mortiarella, found in Nunavut's Frobisher Bay produces mortiamites.
- Mortiamites effectively neutralize a drug-resistant malaria parasite, showcasing the potential of northern discoveries for global health.
The Threat of Warming
- The rapid warming and greening of northern ecosystems threaten biodiversity.
- This loss could mean undiscovered, potentially life-saving natural substances are lost forever.
