What is cryopreservation?

Cryopreservation (freezing at super cold temperatures) of tissue and cells is a technique which puts the cells in suspended animation where they can retain their viability indefinitely. Cryopreservation protects against catastrophic losses caused by such events as disease outbreaks, fire, breeding cessation, or genetic contamination and eliminates the necessity of maintaining stocks 'on the shelf' when those stocks are not being actively used. Cryobiology improved rapidly with the discovery of the beneficial effects of cryoprotectant substances...

What is an electron gun?

It is a device in the back of a "cathode ray tube" television or computer monitor (pre-plasma or LCD flat-panel). The electron gun fires a stream of electrons from the back of the TV onto the inside face of the screen, which is coated with a material that glows when hit by electrons. By using powerful magnets to direct the stream across the screen, a series of dots ('pixels') is built over the screen which appears as an ima...
