Issue 66 - April 2001 : Articles this month
Just add water! - Guido Santacana (Puerto Rico) rediscovers an unused 'Tasco Micro Zoo' kit from the 1960's; a kit to culture protozoa which inspired him in his youth to explore the microscopic world.
Dessert for Dileptus - Rosemarie Arbur (USA) describes a fascinating sequence as two protozoa called Dileptus hunt for food, and an unfortunate protozoan called Cyclidium is the 'dessert'! Illustrated with delightful coloured line drawings.
Hunting micro-aliens: The third and final voyage - The reader is invited to explore as a micronaut some microscopic and macroscopic creatures from a freshwater pond. Your guide and safety officer is Richard Howey (USA).
My cat's ovary - When M Halit Umar's cat needed spaying, it offered a unique opportunity to prepare slides of histological sections. The general features of a mammalian ovary and related features are described and illustrated with excellent photomicrographs of stained thin sections.
Progress on a home-made transmission electron microscope - Few enthusiasts have the skills to safely design and build a TEM, but Robert Holzrichter's (USA) background and expertise has enabled him to achieve this impressive feat. The author shares aspects of the general design and a first image of a diatom which an optical microscope can only just resolve.
Did Gage make these microscope slides? - Simon H Gage was an important figure in the history of American microscopy. Barry Miller (USA) summarises some of Gage's contributions, illustrated with slides prepared by Gage, and asks whether other slides the author owns were also made by him.
Image gallery: Montage of freshwater life photographed using dark-field illumination - An attractive montage created by Ted Clarke (USA) using a home-made lighting set-up based on fiber optics. A larger downloadable image is offered e.g to print out or for use as a screensaver.
The fluid rocking of a suspension of Foraminifera as a means of concentrating samples for the preparation of strews - Brian Darnton (UK) shows how to use this practical way of separating forams from sand samples prior to making slides.
My favourite slides - Paul James (UK) takes a peep at a handful of prepared microscope slides from the latter half of the 19th century. Including attractive papered slides and by famous mounters like Möller, Topping and Norman.
The mystery of the foam on the seashore - Ever wondered what causes it? Wim van Egmond (The Netherlands) takes a closer look at an intriguing algae which, when it blooms, is a cause of this foam.
Digital macroscopy in spring with a flatbed scanner - Dave Walker (UK) explores the capabilities of a flatbed scanner to take macroscopic images of subjects from his garden.
