The video discusses the recent naming of bridgmanite, a mineral that makes up a significant portion of Earth's lower mantle. Bridgmanite was studied indirectly through seismic waves and directly via a meteorite. The video also highlights a unique population of non-migratory humpback whales in the Arabian Sea, which have been isolated for 70,000 years. The video concludes with a call to action for viewers to support science sharing.
