Rhino sperm from the cold

A new mixture of cryoprotectives allows for an unprecedented high motility of frozen rhinoceros sperm after thawing, report scientists from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) in Berlin, Germany. ...

The origin of flower-making genes

Flowering plants have evolved from plants without flowers. It is known that the function of several genes, called MADS-box genes, creates shapes peculiar to flowers such as stamens, pistils and petals. Plants that do not ...

Transport of molecular motors into cilia

Molecular motors produce the force that powers the beat of sperm cell tails to generate movement toward the egg cell for fertilization. New research now shows how the molecular motors that power the movement of sperm cells ...

Female reproductive tract assists swimming sperm

In mammalian reproduction, sperm have a tough task: like trout swimming upstream, they must swim against a current through a convoluted female reproductive tract in search of the unfertilized egg.

Scientists could save thousands with student's DIY microscope

Expensive tests for measuring everything from sperm motility to cancer diagnosis have just been made hundreds of thousands of dollars cheaper by a PhD student from Brunel University London who hacked his own microscope.
