Locomotion and transport of microorganisms in fluids is an essential aspect of life. Search
for food, orientation toward light, spreading of off-spring, and the formation of colonies are …

The central nervous system (CNS) underlies memory, perception, decision-making, and
behavior in numerous organisms. However, neural networks have no monopoly on the …

Activity and autonomous motion are fundamental in living and engineering systems. This
has stimulated the new field of'active matter'in recent years, which focuses on the physical …

Infertility is a growing global health issue with far-reaching socioeconomic implications. A
downward trend in male fertility highlights the acute need for affordable and accessible …

Sperm require a sense of direction to locate the egg for fertilization. They follow gradients of
chemical and physical cues provided by the egg or the oviduct. However, the principles …

Sperm motion near surfaces plays a crucial role in fertilization, but the nature of this motion
has not been resolved. Using total internal reflection fluorescence microscopy, we …

Many motile microorganisms swim and navigate in chemically and mechanically complex
environments. These organisms can be functionalized and directly used for applications …

The infertility of many couples rests on an enigmatic dysfunction of the man's sperm. To gain
insight into the underlying pathomechanisms, we assessed the function of the sperm …

A major goal of regenerative medicine and bioengineering is the regeneration of complex
organs, such as limbs, and the capability to create artificial constructs (so-called biobots) …

All living cells interact dynamically with a constantly changing world. Eukaryotes, in
particular, evolved radically new ways to sense and react to their environment. These …
