Physicochemical studies on po1ynuc1eotides and their components are a relatively new field which, almost daily, attracts an ever- increasing number of scientists.
Cell biology is moving at breakneck speed, and many of the results from studies on insects have helped in understanding some of the central problems of biology.
The editors of this volume have honored me by their invitation to write its Fore- word, an invitation extended because of my editing a book on the maternal behav- ior of mammals in 1963.

These Proceedings are a product of the International Workshop on Seeds held in Williamsburg, Virginia, USA, at the College of William and Mary, during the week of August 6-11, 1989.
Interest in mechanisms of embryo implantation is increasing, particularly with the realization that failure of implantation after in vitro fertilization and embryo transfer places significant limits on the success of treatment.
The belief that energy might be a limiting factor for the development of humanity led twenty years ago to a great interest being'taken in research on anaerobic digestion.
The use of computer-based image analysis systems for all kinds of images, but especially for microscope images, has become increasingly widespread in recent years, as computer power has increased and costs have dropped.
If ripple effect is a measure of greatness in scientific discovery then GEMMOs have a lot going for them and this book dramatically illustrates the risks associated with advances being made by researchers to mobilize and control the power of the microorganism in the world's fight to perfect nature and fmd remedies for its imperfections.
Although blood capillaries were first observed through a flea-lens microscope by Malpighi in 1661,200 more years elapsed before the cellular nature of the vessel wall was conclusively demonstrated.
