Collaborative Intelligence – HW, SW & Systems
China has successfully developed ‘Darwin,’ a neuromorphic chip based on Spiking Neural Networks, a kind of information processing system that mimics the principles of biological brains, an advance that could lead to the development of artificial intelligence systems and Internet of Things.

A Darwinian natural selection algorithm, DarwinTunes, and the musical tastes of 7,000 Internet participants in the experiment, together aimed to create the perfect pop tune. An article on this research entitled Evolution of Music by Public Choice was published June 18 in the journal Proceedings of the National Academy of Sciences (PNAS). Hypothesis: Cultural changes in language, art and music evolve through Darwinian natural selection, as living things evolve. First author, Dr. Bob MacCallum, a mosquito genomics bioinformatician in the Department of Life Sciences at Imperial College London, worked with Matthias Mauch, Austin Burta, and Armand Leroi, Professor of Evolutionary Developmental Biology from the Department of Life Sciences at Imperial College London, and an audience team of 7,000 internet participants, to simulate cultural evolution. Listeners scored loops in batches of 20 on a five-point scale from ‘I can’t stand it!’ to ‘I love it!’. DarwinTunes would then ‘mate’ the top ten loops, pairing them up as ‘parents’ and mingling musical elements of each pair, to create twenty new loops, which replace the original parents and non-parents that were less appealing tunes. Each rating round is one ‘generation’ of musical evolution. DarwinTunes had evolved through 2,513 generations when the article was published.The experiment asked: Can music be produced without a conscious, creative act? What does such music produced in this way sound like? How do “ideal tunes” of different listeners differ? Can those different listener preferences be crowdsourced to converge toward a generally agreed “ideal tune”? Also featured on the BBC, on MSNBC, and in Wired Magazine.

The book Microbes and Evolution: The World That Darwin Never Sawfrom ASM Press celebrates Charles Darwin and his landmark publication, On the Origin of Species. The editors compiled 40 first-person essays, written by microbiologists with a passion for evolutionary biology, to illuminate how each scientist’s thinking and career paths in science were influenced by Darwin’s seminal work.

James Shapiro, author of Evolution: A View from the 21st Centuryand Professor of Microbiology at the University of Chicago, highlighted work presented at a recent conference on Evolution in the Age of Genomics by Peter and Rosemary Grant (Princeton), which emphasized the major role hybridization and introgression between distinct “species” played in producing genetic variability in the wild populations. (Introgression means the introduction of part of the genome from a distinct species.) Whenever there was high inherited variability in a particular population, examination of the DNA indicated that it arose from introgression from a different species. The Grants also described the formation of what would be classed as a new finch species resulting from the full hybridization of two distinct species, in stark contrast to the dictum of the late Harvard biologist Ernst Mayr that distinct species do not interbreed

A cascade of evolutionary change alters consumer-resource dynamics and ecosystem function as authors Matthew R. Walsh, John P. DeLong, Torrance C. Hanley and David M. Post of the Department of Ecology and Evolutionary Biology at Yale University predict that intraspecific evolutionary divergence influences the properties of populations, communities and ecosystems and different ecological impacts of phenotypes and genotypes may alter selection on many species and promote a cascade of ecological and evolutionary change throughout the food web. Their theory predicts that evolutionary interactions across trophic levels may contribute to hypothesized feedbacks between ecology and evolution, although the importance of ‘cascading evolutionary change’ in a natural setting remains unknown.

The German National Academy of Sciences opens with the theme, ‘What is life?’ Leopoldina’s Annual Assembly will discuss the question of life and bridge the gap between natural sciences, the humanities and life sciences, focusing on the Origin of Life, Elementary Life Processes, and Synthetic Life. The meeting includes lectures by Israeli Nobel Laureate in Chemistry (2009), Professor Ada E. Yonath on ribosomes as factories of life, German Nobel Laureate in Medicine (1995) Professor Christiane Nüsslein-Volhard, “On the Evolution of Beauty” (“Zur Evolution der Schønheit”) and will explain how a zebra fish develops from stem cells.

The Sins of Syn-Bio: How Synthetic Biology will bring us cheaper plastics by ruining the poorest nations on Earth. This article arises from Future Tense, a collaboration among Arizona State University, the New America Foundation, and Slate. A Future Tense conference on whether governments can keep pace with scientific advances was held at Google D.C.’s headquarters on Feb. 3-4, 2011. A counterargument was presented by Autodesk Distinguished Researcher Andrew Hessel: Don’t Be Afraid of the Dragon: Fears of synthetic biology are overblown.
Harvard University Arnold Arboretum Director William “Ned” Friedman described how the early history of evolutionary thoughtwill be examined through the lens of Charles Darwin’s highly personal views of his evolutionist ancestors and the question of what set Darwin apart from the dozens of advocates of evolution who preceded him. Friedman described how by the 6th edition of Origin, Darwin credited 34 authors in his historical summary of those who preceded him. Scholars now believe that somewhere between 50 and 60 authors had beaten Darwin in their writings about evolution.

Charles Darwin spent more than eight years studying barnacles, and this work is available online. Recent work by Perez-Losada et al.debunks the view that the more evolved barnacles were more complex, having more shell plates. Barnacle evolution is describedas a revealing principles about evolution in general, referencing also studies of how deep-sea mussels adapt to changes in habitat.

Relevance of Greenhouse Gases to the Origin of Life and its Future
J. Lee Grenfell, an atmospheric chemist at the Technische Universität Berlin in Germany and lead author of the study featured in the journal Astrobiology. “We need to explain how, despite a fainter Sun, the surface could be warm enough to host liquid water.” Gaseous molecules like methane may have worked to heat the planet, keeping the oceans fluid and not frozen. Since liquid water is a prerequisite for Earth’s life, the greenhouse gases may have therefore played an important role in making the planet habitable.
