Making it rain

Drought and water scarcity are becoming a worldwide problem. Manipulating the weather to make it rain by the use of cloud seeding, a technique where certain particles are dispersed in clouds, could be a remedy. Cloud seeding is already used, but is mainly done by using the toxic silver iodide. With team Vsycle we designed an alternative cloud seeding agent that is biological, nontoxic and biodegradable. For this, we used the ice nucleation proteins (INPs) from Pseudomonas syringae, which facilitate ice formation. As the formation of ice crystals in clouds plays an essential role in many environments, this protein is very interesting to use as a potential alternative to silver iodide in cloud seeding. To anticipate on legislation issues regarding GMO’s, we designed INP producing E. coli cells that can be induced to leak their cellular contents according to the bacterial ghost principle.
