**The fully revised edition of Rupert Sheldrakes controversial science classic, from the author of the bestselling Dogs That Know When Their Owners are Coming Home, celebrates its 40th anniversary in 2021!** After chemists crystallised a new chemical for the first time, it became easier and easier to crystallise in laboratories all over the world. After rats at Harvard first escaped from a new kind of water maze, successive generations learned quicker and quicker. Then rats in Melbourne, Australia learned yet faster. Rats with no trained ancestors shared in this improvement. Rupert Sheldrake sees these processes as examples of morphic resonance. Past forms and activities of organisms, he argues, influence organisms in the present through direct connections across time and space.Individual plants and animals both draw upon and contribute to the collective memory of their species. Sheldrake, now Director of the Perrott-Warwick Project supported by Trinity College, Cambridge, reinterprets the regularities of nature as being more like habits than immutable laws. Described as the best candidate for burning there has been for many years by Nature on first publication, this updated edition will raise hackles and inspire curiosity in equal measure.

In Cambridge in the 1950s, several research groups funded by the Medical Research Council were producing exciting results. In the Biochemistry Department, Sanger determined the amino acid sequence of insulin, and was awarded a Nobel Prize for this in 1958. At the Cavendish Laboratory, in the MRC Unit for the Study of the Molecular Structure of Biological Systems, Watson and Crick solved the structure of DNA, and Perutz and Kendrew produced the first three-dimensional maps of protein structures haemoglobin and myoglobin for which all four were later awarded Nobel Prizes. This made it timely to create, in 1962, a new Laboratory of Molecular Biology in Cambridge by amalgamating these groups with other MRC-funded groups from London. The Laboratory has become one of the most successful in its field, and the number of Nobel Prizes awarded over the years to scientists at LMB has risen to thirteen. This book follows the development of LMB, through the people who moved into the new Laboratory and their research. It describes events and personalities that have given the Laboratory a friendly, family atmosphere, while continuing to be scientifically productive.

Desde hace milenios, las más diversas y poderosas civilizaciones humanas se han sentido elegidas por las divinidades, depositarias de la verdad y de derechos de abuso y explotación. El gran clasificador Carl Linneo denomino homo sapiens a seres especializados en el saqueo y la devastacion, colocandolos en la cima de la piramide evolutiva. A la vista de los resultados, tal vez sapiens solo sea la ensoñacion taxonomica de una especie que aun estaria por llegar.Las ciencias, tecnologias, artes, politicas o pensamiento que en sus fundamentos no incorporen sus propias especificidades devolucionarias, respecto a lo historicamente expoliado, solo contribuiran a la barbarie civilizada, a la prorroga del silencio, al exterminio de los recursos y de la diferencia.La desclasificacion aporta, al ideal devolucionario, modalidades abiertas, plurales y particularmente contradictorias, de pensar y conocer.El autor recoge, en varios centenares de ejercicios desclasificados y cuatro ensayos sinteticos sobre desclasificacion, reflexiones e intuiciones, tan cargadas de dramatismo y autocritica como de humor o ironia, fraguadas en una racionalidad paraconsistente y, por ello, radicalmente sensible.
