A letter, not a blast
The Scent Letter
Science, smell, and what it means to stay sharp. Sent when it matters.
A letter, not a blast. Every issue brings one personal opening, one piece of olfactory science explained clearly, one practice you can try this week, three things I'm reading or smelling, and a P.S. you'll probably like. About 5 minutes to read.
