II.—Note on Nautilus robustus, Foord & Crick

On the Visual System of Nautilus Pompilius

The anatomy of the eye of Nautilus pompilius Linnaeus was studied, using light and electron microscopy. The outer and inner surfaces of the iris were found to be lined with columnar epithelium bearing microvilli, except for the groove running ventrally from the pupil over the outer surface of the iris, where the epithelial cells bear cilia. Many mucus cells are also present. The epithelium of t...

A Short Survey on Watson-Crick Automata

This paper surveys some known results in Watson-Crick automata theory. In particular, we concentrate on the computational power, complexity measures, decidability problems, and systems of Watson-Crick automata working together on the same input. This selection of topics is not exhaustive, reflecting the research interests of the authors. A series of open problems and questions is also included.

Francis Crick 1916–2004

In March 1953, 31 years after Howard Carter’s astonishing first glimpse into Tutankhamun's tomb, an even more golden treasure was found. Francis Crick and Jim Watson shared that moment of discovery as they looked, for the first time, into the heart of all living things. They saw the structure of DNA, and their vision became the big bang of modern biology. Francis’ life in research began inauspi...
