The Science of Screaming, And What Was the Biggest Dinosaur?

The video explores the unique characteristics of human screams, highlighting a study by NYU researchers that identifies 'roughness' as a key feature distinguishing screams from other sounds. Brain scans reveal that screams activate the anterior amygdala, linked to fear. The video also revisits the discovery of the dinosaur Dreadnoughtus, initially thought to be the largest ever found. A new study suggests it was smaller than first estimated, using a computer model to reassess its mass. The video concludes by inviting viewers to discuss these scientific findings.
