The interaction of living materials with inanimate materials via physical and chemical reactions poses an acute danger for the longevity of our cultural heritage, as long as it exists in the material form and not in that of the invincible word. Th...

Nonliving organic matter (NLOM) comprises the bulk of the organic carbon stored in the terrestrial biosphere and a major part of the organic carbon in the sea. Organic substances, which include litter, marine detritus, dissolved organic matter, an...

At the turn of the century, the pioneering neuroscientist Ramon y Cajal articulated the hypothesis that growth processes involved in the development of the central nervous system may persist into adulthood, where they might be retained to mediate ...

In 1993, an International Task Force for Disease Eradication evaluated over 80 potential candidate diseases and made recommendations. However, little has been done to develop the science of eradication systematically. This book reports the finding...

In recent decades, the biosphere has become increasingly stressed, often beyond the point where the internal structure and function of ecosystems are sustained. We have experienced an intensified "exploration" of natural system resources to suppor...

3 There are other trends in the attempt to meld evolution and development which immodesty permits me to add. I have been concerned over the years with the selection forces which might have produced larger organisms and therefore a development of i...
