This article develops a phenomenological approach to examine the intersection of global migration and rising concerns about disinformation. Drawing on interviews with Venezuelans en route to the United States-Mexico border through Central America, th

Motility is a fundamental survival strategy of bacteria to navigate porous environments. Swimming cells thrive in quiescent wetlands and sediments at the bottom of the marine water column, where they mediate many essential biogeochemical processes. W

Hay profundas desigualdades y hegemonía de la academia del Norte Global ejemplificadas por publicaciones, referencias y cuerpos editoriales de revistas, y el lugar preponderante del inglés como lingua franca de la academia global. Esto contribuye a

Viscoelastic flows transition from steady to time-dependent, chaotic dynamics under critical flow conditions, but the implications of geometric disorder for flow stability in these systems are unknown. Utilizing microfluidics, we flow a viscoelastic

Bacteria often reside within complex microenvironments through which they have to navigate efficiently. This paper presents an experimental study of bacterial motility and dispersion within ordered and disordered arrays of obstacles as a proxy to a r

Abstract In the context of global change and enhanced toxic cyanobacterial blooms, cyanobacterial transfer to estuaries is likely to increase in frequency and intensity and impact animal and human health. Therefore, it is important to evaluate the po

This article analyzes social media engagement when elections are adjudicated to one of the contending parties. We extend existing models of political dialogue to explain differences in social media engagement (i.e. time-to-retweet) when users support

Microswimmers can navigate porous environments, however the impact of their directed motility on their movement in fluid flow remains an open issue. The authors show that the motility of magnetotactic bacteria in flow through a porous constriction gi

Magnetotactic bacteria (MTB) are fascinating micro-organisms which possess embodied biomineralized nanomagnets providing them the ability to orient with the Earth's magnetic field. This property is presumably related to an evolutionary advantage in f

Active matter is a new class of material, intrinsically out-of equilibrium with intriguing properties. So far, the recent upsurge of studies has mostly focused on the spontaneous behavior of these systems --in the absence of external constraints or d
