On episode #6, here are the main ideas:

1. Is a mask really necessary when just talking? Can the coronavirus be transmitted through normal speech? A new study uses lasers to look at how respiratory droplets are emitted during normal speech.

2. Scientists revisit the famous psychology experiment the marshmallow test, revealing new insights into self-control behavior and how it may have something to do with managing our reputation, and its relevance for the future.
