A mightier mouse

Article Abstract:

Knockout mice are laboratory strains used by molecular biologists to shed light on the activities of the brain. A new generation of knockout mice was engineered by researchers to lack a specific gene for them to be able to zero in on what happens when a particular gene is missing as a gene may have various functions in different parts of the body at different times. A specific gene, one that affects the development of spatial memory, was deleted only in certain cells in the brain and only after neural circuitry has developed. The 'regional gene knockout technology' helped researchers determine which molecule strengthens the neural connections that lead to spatial memory and where that molecule exerts its effect.

The virtues (and vices) of virtual colleagues

Article Abstract:

'Electronic collaboratories' link scientists with their colleagues through computers. Scientists can then perform experiments in front of their computers and study data collected from afar. They can also jointly analyze data and study real-time observation through chat boxes. William Wulf, who came up with the word in 1989, said that it is a 'center without walls' where scientists can do research without doing field work. Collaboratories compress geographical distance when scientists at different sites conduct their experiments together.

All the world's a page

Article Abstract:

David Small is the proponent of the Virtual Shakespeare project. It is an attempt to present the complete dramatic texts of William Shakespeare in an easy an intuitively navigable form. Users of Virtual Shakespeare can view Shakespeare's works in three dimensions, so they always know where they are within the larger text in a particular work. They can view significant information even from afar.
