How do growing bacterial colonies get their shapes? While colony morphogenesis is well
studied in two dimensions, many bacteria grow as large colonies in three-dimensional (3D) …

Collectives of actively moving particles can spontaneously separate into dilute and dense
phases—a fascinating phenomenon known as motility-induced phase separation (MIPS) …

During the growth of a cell collective, such as proliferating microbial colonies and epithelial
tissues, the local cell growth increases the local pressure, which in turn suppresses cell …

Bacteria are ubiquitous in our daily lives, either as motile planktonic cells or as immobilized
surface-attached biofilms. These different phenotypic states play key roles in agriculture …

Collective migration—the directed, coordinated motion of many self-propelled agents—is a
fascinating emergent behavior exhibited by active matter with functional implications for …

In recent years, nonreciprocally coupled systems have received growing attention. Previous
work has shown that the interplay of nonreciprocal coupling and Goldstone modes can drive …

A key feature of many living systems, such as bacteria and eukaryotic cells, is their ability to
actively self-propel. Indeed, cellular motility underlies numerous critical biological …

We present the interpretable meta neural ordinary differential equation (iMODE) method to
rapidly learn generalizable (ie, not parameter-specific) dynamics from trajectories of multiple …

Motility and nonreciprocity are two primary mechanisms for self-organization in active matter.
In a recent study [Phys. Rev. Lett. 131, 148301 (2023)], we explored their joint influence in a …

From the mitotic spindle up to tissues and biofilms, many biological systems behave as
active droplets, which often break symmetry and change shape spontaneously. Here, I show …
