From the paper.
Ultrasounds accelerate extraction processes due to acoustic cavitation [8], [9]. When acoustic bubbles, also called inertial bubbles, collapse near solid materials, such as coffee grounds, they generate micro-jets with the force to fracture the cell walls of plant tissues, intensifying the extraction of the intracellular content [10].
Seems more involved than just aggressive stirring.

I've seen the Charlton Heston one, and the 2001 Mark Wahlberg one. The original was obviously better. I hadn't seen any of the current cycle until I saw Kingdom last weekend. It was fine.
I listened to a recap of the previous 3 films and it didn't matter. Kingdom takes place "many generations" after the third movie so all the other characters are dead. Kingdom's story works fine as a standalone film. It's not amazing, but there's nothing particularly awful about it. Now I'll probably see the next couple, but they're not high on my list.
