Martin Walker Interview with Martin Walker
Martin Walker grew up in Whitley Bay on the North East coast of England. In 1981 he received a BSc (Hons) degree in chemistry from the University of Bristol. After graduation he went to work for Fine Organics, Ltd., in the north east of England, where he worked in R&D, developing manufacturing processes for fine chemicals (pharmaceutical intermediates, etc.).

? Hula-Hoop DNA Amplification? Periodic nanostructures made of gold nanoparticles and long DNA strands with repeated sequences have been prepared by Michael Brook, Yingfu Li, and colleagues at McMaster University, in Hamilton, Canada. Their approach exploits a technique for duplicating DNA known as "rolling circle amplification" or the "hula-hoop" technique.
? Metals Take on Carbon's Bonding Characteristics? A rethink about chemical bonding might be in the cards thanks to research that shows that the metal indium forms bonds in a manner not dissimilar to organic carbon atoms. Extended, or catenated, chains of atoms are common in carbon compounds, but UK chemists have found that they can make chains of indium atoms linked by single bonds.
? Bacterium's Sticky Solution
A harmless bacterium that lives in waterways could be using nature's strongest adhesive, according to findings by US researchers. Bacteriologist Yves Brun of Indiana University Bloomington and Brown University physicist Jay Tang and colleagues have identified a natural chemical produced by Caulobacter crescentus and found it to be one of the strongest glues known.
