Endless Form: Chas. Darwin and the Visual Arts

If I could travel back in time, my first stop might be on board the HMS Beagle circa 1834, followed by a hop over to Cambridge, England in early 2009 to catch the Darwin Endless Forms exhibit at The Fitzwilliam Museum before it closed.

Fortunately, books can have the power to transport our minds, if not our bodies, to such magical places. This is certainly the case with the exhibit’s companion volume Endless Forms: Charles Darwin, Natural Science, and the Visual Arts. The essays match the quality of the illustrations, making this book much more than your typical museum trophy / coffee table decoration.

King of Beasts meets Endless Form, Pennsylvania 2014

This book provides rich visual context for thinking about Darwin as an individual, and the influences he experienced from painting, drawing, natural histories, geology and culture. Chapter four entitled ‘Art and the Entangled Bank: Colour and Beauty of of the War of Nature’ is one of my favorites. It opens with a quote from Darwins Origin of Species, a vision of of a lush, interconnected nature “with birds singing on the bushes … worms crawling through the damp earth.” Among the many gorgeous examples that illustrate this theme, I was struck by Joseph Mallord William Turner‘s painting of The Flood as a naturalistic landscape (especially since seeing Mr. Turner), and by a diorama (progenitor of the theoretical diorama?) from Biologiska museet in Stockholm.

Attenuation is the New Aggregation

Show notes from the archives of IT Conversations …

The attention economy promises to solve problems by harnessing the power of the network, but in the meantime, we are being deluged by the glut of information aggregating in our inboxes and on our devices. Alpha geeks may rejoice as they imagine new heuristics to catch up with this information overload. In reality, for most of us, every waking moment has been absorbed by the task of simply keeping up. In this talk, Rael Dornfest delivers an entertaining riff on the potential for ‘attenuation’ to help us tame the infosphere by distilling out the most interesting and useful bits from the network soup.

The scientific traditions of collaboration, transparency and sharing can be at odds with the constraints of publishers, patents and copy protection. Science Commons is a new project of the Creative Commons with a mission to facilitate the growth of an openly accessible commons for scientific knowledge. In this talk, Paula Le Dieu maps out some of the alternative models for journal publishing, licensing and data sharing which can help promote the flow of scientific results and innovation.

The Dunbar number is a measure of the cognitive limit to the number of individuals with whom a person can maintain stable relationships. The concept has intrigued sociologists and anthropologists since it was first recognized as the correlation between brain capacity and group size in primates. In this talk, social software observer Christopher Allen discusses the interesting implications the Dunbar number theory has for the gathering of humans on line in the digital age.

Memes

Show notes from the archives of IT Conversations …

Memetics is an intellectually rich but controversial field which seeks to explain how our minds and cultures are designed by natural selection acting on replicating information, just as organisms evolve by natural selection acting on genes. Sue Blackmore, one of the field’s leading thinkers, skillfully unfolds the major arguments for a meme’s-eye view of the world, and explores the implications for humanity. Are our brains best seen as machines invented by and for propagation of selfish memes?

Roles for Mismatch Repair Factors in Regulating Genetic Recombination

Mismatch repair (MMR) systems are evolutionarily conserved and play a primary role in mutation avoidance by removing base-base and small insertion-deletion mismatches that arise during DNA replication (31). In addition, MMR factors are required for the repair of mismatches in heteroduplex DNA (hDNA) that form as a result of sequence heterologies between recombining sequences (641,43). MMR also acts to inhibit recombination between moderately divergent (homeologous) sequences (1142). The roles of MMR during recombination are believed to reflect the interaction of MMR factors with mismatches that arise in hDNA or possibly with other structures such as Holliday junctions (233). The full range of effects that MMR can exert on mitotic and meiotic recombination have been discussed elsewhere (11) and will only be summarized briefly here. The purpose of this review is to highlight recent results that have furthered our understanding of interactions between MMR factors and mitotic recombination intermediates.
