Studying a cell's crawling motion in a fluid

Cell motility, the spontaneous movement of cells from one location to another, plays a fundamental role in many biological processes, including immune responses and metastasis. Recent physics studies have gathered new evidence ...

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 ...
