Sperm cells move through fluids that should stop them almost instantly, yet new research suggests they succeed by exploiting unusual properties of active living matter.

Dark-field microscopy of individual sperm at 200 frames per second in media with varying shear rates (Scale bar is 20 micron) Sperm can modulate their energetics by regulating their flagellar waveform ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Sperm can modulate their energetics by regulating their flagellar waveform -- how the sperm oscillate their tails -- in order to adapt to varying fluid environments, potentially optimizing their ...
