Just as DNA chips revolutionized genome analysis, we hope to make cell chips (self-assembled arrays of cells on a thumbnail-sized chip) using our DNA-based cell adhesion strategy. Cell chips could be used as biosensors for detecting the presence of pathogens, or for drug screening, just to name of a few of the many possibilities.

In none of the cases examined in this study was the existence of these gun registration records of any assistance in detecting a crime and no one questioned during the course of this study could offer any evidence to establish the value of the system of registering weapons.

There is no way in which to understand the world without first detecting it through the radar-net of our senses.

There is much evidence showing that animals have sophisticated systems for regulating their lives and that they are much disturbed if they cannot control certain aspects of what happens to them. There is also good evidence for elaborate systems for detecting and responding to painful stimuli.

Colonoscopy has proven to be an effective method for preventing colorectal cancer by detecting and removing polyps that have the potential to develop into colorectal cancer as well as finding early cancers that are more effectively treated.

However much we talk of the inexorable laws governing the life of individuals and of societies, we remain at the bottom convinced that in human affairs everything in more or less fortuitous. We do not even believe in the inevitability of our own death. Hence the difficulty of deciphering the present, of detecting the seeds of things to come as they germinate before our eyes. We are not attuned to seeing the inevitable.
