Smoke explosions. Fire tornadoes. Burning couches. It all happens in the fire lab: a purpose-built facility where researchers can safely set stuff on fire and study how it burns, for science.

How do you go about dissecting the world’s rarest whale? In December 2024, images from a concrete room in Mosgiel, just south of Dunedin, spread around the world as a team of people spent a week doing a scientific dissection on a spade-toothed whale that had washed up five months before.
