Beschreibung

Cells and organisms constantly process highly noisy information;their biological computing controls vital functions such as self-assembly and motility. Biological systems display an astonishing capacity to integrate noisy and possibly conflicting signals, and can even tolerate structural variations of their "signaling hardware”. Interestingly, biological computing is not just robust per se, but adapted to the system-specific sources of noise. As a specific example, I will discuss closed feedback loops that enable robust motility control in flagellated microswimmers. Such control loops guide e.g. sperm to the egg or synchronize the oscillations of several flagella. By studying principles of noise filtering, sensory adaptation, and resilience in these biological systems, we can draw inspiration for engineered computing systems.
