A “walk” in composition space for a lipid world molecular assembly, shown in simplified 3 dimensions. A point on the line signifies a specific composition along the time axis, whereby the three coordinates are amounts of the three different molecule types. A composome (pink background) is a time interval when the composition stays almost unchanged, signifying compositional replication.

Lighting up the reward center: Light-sensitive proteins are inserted into specific brain cells. Blue: dopamine-producing cells in the reward system in the ventral tegmental area. Red: cells carrying the inserted protein in a mouse brain. Yellow: Overlap between cells that are carrying the optogenetic protein and those that are dopamine-producing.
