Diet has rapid effects on sperm quality

Sperm are influenced by diet, and the effects arise rapidly. This is the conclusion of a study by researchers at Linköping University, in which healthy young men were fed a diet rich in sugar. The study, which has been published ...

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. ...

Discovery reveals tractionless motion is possible

In an article published in Physical Review Letters, Bristol scientists have answered the fundamental question: "Is it possible to move without exerting force on the environment?", by describing the tractionless self-propulsion ...

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.

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 ...

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 ...

Cells are crawling all over our bodies, but how?

(PhysOrg.com) -- For better and for worse, human health depends on a cell's motility -- the ability to crawl from place to place. In every human body, millions of cells –are crawling around doing mostly good deeds -- ...
