The slower the pictures move, the better your ability of handling stress. Alleged criminals that were tested see them spinning around madly; however, senior citizens and small children see them standing still. None of these images are animated - they are perfectly static.

Biological ControlsBiological Controls

In quarantine tests, potential biological pests are confined in small cages containing test plants sprayed with different

microbiological control agents.

BiotechnologyBiotechnologyThe application of biological knowledge and techniques

to develop products

A potential product from guano microorganisms is an enzyme called chitinase, a protein capable of converting the chitin exoskeleton of insects and crustaceans to simpler sugars. This, in turn, may be used for alcohol fuel production. Another potential use for chitinase producing microorganisms is the biological control of insect and nematode pests.

Genetic Engineering / Gene TherapyGenetic Engineering / Gene Therapy

Using bacteria of genus Clostridium to selectively penetrate cancer tumors and deliver gene therapy to shrink an kill the tumors.

In gene therapy, viruses are used to carry replacements for defective or missing genes into human cells
