Early electronic valve, diagram

Audion amplifier. Diagram of an Audion triode valve that was the first amplifier. It was invented by Lee De Forest in 1907. De Forest worked on vacuum tubes, which act as diodes (devices that allow electricity to flow one way only). The addition of a grid (yellow) allowed the amplification of weak radio signals (top), which made radio a practical method of transmitting information

Ultraviolet fluorescence LM of BHK Cells Featured 14 Jan 2004 Print

Ultraviolet fluorescence LM of BHK Cells

Ultraviolet fluorescence light micrograph of BHK (baby hampster kidney) tissue culture cells labelled with anti-tubulin to show the micro- tubular structure. Microtubules, together with microfilaments (not seen here), form a three- dimensional array known as the cytoskeleton. This fibrous network, only recently observed using ultraviolet light & fluorescent stains, is still poorly understood. Microtubules, more rigid than microfilaments, are thought to act as direction markers in the cell. In this image the oval depression at the centre of each cell is the space occupied by the nucleus. The microtubules radiate from the nucleus to the periphery of the cell
