Bugscope is a new educational project in the World Wide Laboratory. The World Wide Laboratory provides Web browser based control of scientific imaging instrumentation using the Internet [1]. Providing K-12 classrooms with web based remote access to sophisticated scientific imaging systems was initially demonstrated by us in 1996 in the Chickscope project [2,3]. Chickscope allowed students to study chicken embryo development using a remotely controlled magnetic resonance imaging (MRI) system from their classrooms. While the Chickscope project was highly successful, the resources required to provide operational support for the remote imaging aspects of the project for a small number of classrooms were enormous and the project was not sustainable. The Bugscope project builds on the methods developed and the lessons learned from the Chickscope project. The primary goal is to demonstrate that relatively low cost, sustainable access to an environmental scanning electron microscope (ESEM) can be made available to K-12 classrooms to examine arthropods.

Methods: Classrooms use a standard web browser over the Internet to control and acquire images from a Philips XL-30FEG ESEM. The architecture to support remote acquisition is shown in fig. 1. The client/server control architecture for the ESEM remote control server is based on the emScope control library [4].

The blood supply of the liver is of dual origin, namely the hepatic artery and the portal vein. The physiological implications of this dual blood supply are well understood (1), the morphological details of the terminal afferent vessels, however, still need to be further investigated. Particularly the various possible types of entry of the terminal afferent vessels into the sinusoids are not yet fully understood. With the aid of a newly developed method, i.e. the combination of detection of a marker substance (with the aid of EDX) and scanning electron microscopy, many of the morphological parameters have been elucidated (2). This new method involves the injection of the liver from two sides (arterial and portal vessels) with methacrylate or Mercox containing either of two different marker substances, both of which can be detected with the aid of an EDX detector. Thus the terminal afferent vessels can easily be told apart (2, 3).
