April showers bring May flowers, but the reverse may also be true. Two studies show that pollen and fungus-generated material broken up into nanometer-sized fragments effectively nucleate water droplets and ice in lab experiments, suggesting that such particles play an important role in seeding clouds and promoting precipitation (Geophys.
