The silver iodide particles supercharge cloud formation, as they act as excellent condensation nuclei. Once clouds form, they also start a positive feedback effect. As droplets freeze and are added to the cloud, they release their heat, creating an updraft which draws additional moisture from the ground into the atmosphere...
...Fittingly, the initial discovery of the potentially neurotoxic effect of anesthesia occurred by accident. In the 1990s, scientists discovered that the brain cells of patients in the midst of a stroke were flooded with calcium. Doctors wishing to treat these patients hypothesized that blocking the receptor that enables calcium to enter cells could protect stroke patients from severe brain damage. But in the course of researching this possibility, they found that switching off the receptor in a healthy brain cell led to the death of that cell - an unexpected and troubling result, given that many common anesthetics block the same...
...sure, the Mediterranean's ecosystem is more diverse - and thus more robust - than the Black Sea's. So only time will tell what kind of effect the Mnemiopsis will have.
