Macromolecular crowding can serve as a design tool for controlling the formation and organization of synthetic DNA droplets, a study from Science Tokyo reveals. Researchers investigated this strategy using DNA nanostars and polymeric crowding agents to mimic the crowded cellular environment. They found that crowding promoted droplet formation and enabled control over droplet size, interactions and organization.
The findings could support the development of programmable artificial cell systems.

Same radical, different paths: X-ray snapshots reveal how neighboring molecules shape its movement
Chemical reactions have their own "impatient molecules." Unable to stay still even for a moment, they latch onto other molecules indiscriminately. Researchers have now found that even these molecules change where they "sit" and how far they roam depending on who their neighbors a
