Abstract For more than three centuries we have been watching and studying microscopic phenomena behind a microscope. We discovered that cells live in a physical environment whose predominant factors are no longer those of our scale and for which we l

Most biological and artificial self-propelled particles tend to be attracted by solid walls on their swimming pathways. Vizsnyiczai et al. show that, unexpectedly, confining E. coli cells inside a channel triggers stable locomotion along the channel

Light can be used to rotate micrometric turbines that usually rely on scattering to redistribute optical momentum and generate a mechanical torque. Here, 3D microfabricated light guiding structures can reroute an incoming flow of optical energy to ge

Bacteria are able to propel themselves and thus drive systems out of equilibrium. Here the authors aim to control this motion and exploit it in microengineered motors which are powered by genetically modified bacteria and driven by light.

Many motile microorganisms react to environmental light cues with a variety of motility responses guiding cells towards better conditions for survival and growth. The use of spatial light modulators could help to elucidate the mechanisms of photo-mov

Self-propelled particles, both biological and synthetic, are stably trapped by walls and develop high concentration peaks over bounding surfaces. In swimming bacteria, like E. coli, the physical mechanism behind wall entrapment is an intricate mixtur

High Frequency radio waves reflected by the ionosphere can provide a relevant amount of information within the composite received signal. The ionosphere is indeed a frequency dispersive, bi-refractive, absorbing medium, in which multipath propagation
