The particles are so small they should not last very long. You couldn't have the E ring just sit there for the age of the solar system. It had to be regenerated somehow.

The fluorocarbon particles are pretty small, and you don't want those sitting in your lungs.

We're sticking to what we can infer from our instrument, and we are not directly seeing temperatures warm enough for liquid water.

Particles have been used to stabilize emulsions and foams for over 100 years. However, we've demonstrated that not only are particles useful for making bubbles last longer, they fundamentally alter the properties of these bubbles. Instead of behaving like a fluid surface that flows to balance unequal stresses, the 'armor' of particles on the surface of the bubbles actually supports the unequal stresses inherent in non-spherical shapes.

Particles of the allergen -- in this particular case, peanuts -- are small enough to actually float in the air, ... If they land on someone who is allergic, land in their eyes or in their nose, they can cause them an actual allergic reaction.

It is the commencement of a battle. I suspect Dubai Ports are not going to sit on their hands. Shareholders will get more at the end of the day.
