This chapter explores the findings of a new-ish moon orbiting Saturn that contains a hidden ocean located 20 to 30 kilometers beneath its surface, raising the potential for extraterrestrial life.
00:45 Smoking's long-term effects on immunity
It's well-known that smoking is bad for health and it has been linked to several autoimmune disorders, but the mechanisms are not fully understood.

The team hopes that this evidence could help better understand smoking's association with autoimmune diseases.
