In an unexpected twist, an atmospheric particle's stickiness protects it from sunlight when the air is cool and dry. The particle's sticky nature, or viscosity, slows down the motion of molecules inside. The result is that ...

For the past 20 years, a large portion of the particles measured in the atmosphere were missing from models. At best, models were able to explain one-tenth of the carbon-rich secondary organic aerosols, or SOA, measured in ...
