In its original form, Gibbs-Boltzmann statistical mechanics cannot describe “active matter,” such as living, driven, or self-propelled systems. Contemporary models of swarming and flocking behaviors, ...

Biology solves a myriad of seemingly impossible physical challenges through the magic of active matter. Consider our lungs, for example. Using active-matter surfaces, they clear an astronomically ...

Physicists are using small wheeled robots to better understand these indirect mechanical interactions, how they play a role in active matter, and how we can control them. When self-propelling objects ...

Ants are social insects and the Solenopsis invicta species -- known as the fire ant -- is no exception. The social interactions of this invasive insect, which comes from South America, are framed ...
