Title: Organic hazes as a source of life's building blocks to warm little ponds on the Hadean Earth.

Over 4 billion years ago, Earth is thought to have been a hazy world akin to
Saturn's moon Titan. The organic hazes in the atmosphere at this time could
contain a vast inventory of life's building blocks, and thus may have seeded
warm little ponds for life. In this work, we pro [...]
