Ken Jones, a leading amateur microscopist, specialises in video-filming pond-life. One of his videos captures the enigmatic and graceful movement of Volvox, and he has kindly allowed us to show some extracts from his film on this page. A single Volvox colony spins through the dark waters of a pond. Daughter cells are just visible inside. Micscape Editor's note.

When the body retains salt it also holds on to fluid and thereby may cause some oedema. A possible cause of fluid retention often overlooked by people and difficult to diagnose is due to binge eating alternating with strict dieting. This can cause intermittent fluid retention.Mild swelling of the feet, hands, tummy (abdomen), breasts and face may occur.lthough there is no cure for idiopathic oedema, having a healthy diet which is low in salt can make a real difference. Support stockings and regular exercise are also beneficial. Oedema is the medical term for fluid retention. Idiopathic is a term which means unknown cause.
