Liquid crystal droplets as versatile microswimmers

Nature's most common swimmers are single-celled organisms such as microalgae that swim toward light sources, and sperm cells that swim toward an ovum. For a physicist, cells are simply biochemical machines, which must obey ...

Survival of the females

It is well known that many mammals are able to adjust the ratio of male and female young depending on the surrounding conditions at the time of conception. A recent study in the group of Christine Aurich at the University ...

A molecular delivery service

Tiny hair-like structures (cilia) are found on the surface of most cells. Cilia are responsible for the locomotion of cells (e.g. sperm cells), they process external signals and coordinate the correct arrangement of the inner ...

Keeping sperm cells on track

An essential component of every eukaryotic cell is the cytoskeleton. Microtubules, tiny tubes consisting of a protein called tubulin, are part of this skeleton of cells. Cilia and flagella, which are antenna-like structures ...

Female gametes prefer sperm with different immune genes

Through clever partner selection, animals can increase the future success of their offspring. With some species, this process continues even after the sex act. Researchers at the Max Planck Institute for Evolutionary Biology ...
