The major features of evolution are pre-determined and not only the result of random or accidental processes, two leading European scientists propose in a paper published in the Journal of Theoretical Biology .
Professor Robert Williams of the University of Oxford and Professor Fraústo da Silva of the Instituto Superior Tecnico of Lisbon, challenge the Darwinist idea that the overall course of evolution random and purposeless, and that the appearance of organisms with increasing complexity (including man) is ‘sheer luck’.
In a polemic argument likely to fuel the controversy of Intelligent Design – the idea of a hidden hand behind life as supported by Creationists - Williams, an Oxford Emeritus Professor of Inorganic Chemistry, and Fraústo da Silva, Professor of Analytic Chemistry, propose that evolution is directly influenced by the changes in the chemical environment. This theory snubs the Creationists’ major criticism of Darwin by explaining how evolution follows a trail of increasing complexity without relying on the existence of a ‘supernatural’ entity.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
