Today, more than one third of children are born to unmarried mothers in a number of Western Countries. Evidently, activities formerly confined to the realms of marriage are no longer so. Does marriage have a future or is it condemned to the scrap heap of history? And does it matter? Arguably, to answer such questions we need to have a grasp on what marriage is.

A review is presented of some of the observed features of cluster formation in our Galaxy and in external galaxies. Evidence is summarized suggesting that star clusters form only in the densest parts of large star-forming complexes, and that the molecular clumps in which they form are compressed in part by the effects of earlier star formation. The formation of massive globular-like clusters ap...

MicroRNAs (miRNAs) are approximately 22 nucleotide (nt) non-coding RNAs that participate in gene regulation. MiRNAs confer their regulation at a post-transcriptional level, where they either cleave or repress translation of mRNAs. Over 3000 identified mature miRNAs exist in species ranging from plants to humans, suggesting that they are ancient players in gene regulation. A relatively small num...

I have been asked to talk about some publishing scenarios for the future. We all know the danger in this – a couple years from now, someone will find this presentation and remind me how silly some of these predictions are. On the other hand, you cannot operate a business unless you are thinking about where the world is heading, so this is a risk that comes with the territory, even if it inevita...
