Investigating the motility of swimming Euglena

Some species of Euglenids, a diversified family of aquatic unicellular organisms, can perform large-amplitude, elegantly coordinated body deformations. Although this behavior has been known for centuries, its function is ...

How bacteria mobility is like human locomotion

Do bacteria control their "walks" like we do? It might sound strange, but it's a fundamental question. Understanding bacteria motility would not only expand our understanding of their behavior, but would also contribute to ...

Discovery of the oldest evidence of motility on Earth

An international multi-disciplinary team coordinated by Abderrazak El Albani at the Institut de chimie des milieux et matériaux de Poitiers (CNRS/Université de Poitiers) has uncovered the oldest fossilised traces of motility. ...

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 ...

Researchers establish key mechanism controlling cell division

Researchers at the Francis Crick and Gurdon Institutes have pinpointed the mechanism that activates a key point in embryonic development. This could help scientists develop new treatments for diseases where the cell cycle ...

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 ...

An up-close view of bacterial 'motors'

Bacteria are the most abundant form of life on Earth, and they are capable of living in diverse habitats ranging from the surface of rocks to the insides of our intestines. Over millennia, these adaptable little organisms ...
