MIGRATORY PATH AND GENES. "Many components of migratory behaviour, such as the amount, timing and intensity of migratory activity, are under strong genetic control, at least in small night-migrating passerines. Also cross-breeding experiments among groups of European blackcaps (Sylvia atricapilla) that differed in migratory behaviour indicated a strong genetic basis of this behaviour." http://rspb.royalsocietypublishing.org/content/early/2011/02/11/rspb.2010.2567 View in LinkedIn

MIGRATIONAL PLASTICITY. "A strong evolutionary reduction of migratory activity has been observed in a blackcap population, presumably in response to climate change. These results suggest that the evolution of migratory behaviour in a resident population or of residency in a migratory population may be a common and rapid process." http://rspb.royalsocietypublishing.org/content/early/2011/02/11/rspb.2010.2567 View in LinkedIn

STRONG SUSPICIONS. "High genetic correlations among incidence, amount, intensity and timing of migratory activity in blackcaps suggest that these components of migratory behaviour are influenced by common genetic mechanisms." http://rspb.royalsocietypublishing.org/content/early/2011/02/11/rspb.2010.2567 View in LinkedIn

SO ENDS this first of two weekends on the sense of place as exhibited in migratory creatures. We live on a planet full of restless beasts, which have two homes, and long distances between them. On the face of it, it seems a perilous arrangement, or at least a wasteful one; many perish on these long journeys, both the young and the old. And as the beloved swallows prepare to migrate here in Spain, it is impossible not to wonder about their Herculean efforts. View in LinkedIn

CELL MIGRATION. “Collective migration is a type of cell movement wherein groups of cells move together as a coherent unit. Collective migration is involved in multiple aspects of development across many organisms. Different forms of collective migration are observed in many biological processes such as gastrulation, tubulogenesis, neural crest migration and wound healing. Cancer cells can also spread via collective migration in the form of cellular streams.” https://lnkd.in/dz4nHjA View in LinkedIn

CELL MOBILITY. “The hallmark of collective migration is the action of cellular mechanisms that control and shape the motility of the individual cells in the group. Despite the broad impact on normal development and disease, the molecular mechanisms that facilitate collective migration are still not well understood.” https://lnkd.in/dz4nHjA View in LinkedIn

MOLECULAR INFORMATION LIMITS. "Traditional robots rely for their function on computing, to store internal representations of their goals and environment and to coordinate sensing and any actuation of components required in response. Moving robotics to the single-molecule level is possible in principle, but requires facing the limited ability of individual molecules to store complex information and programs." (The Lund bot). https://lnkd.in/dyH7qBg View in LinkedIn

MOLECULAR SWARMS. "We anticipate that this strategy will result in more complex robotic behaviour at the molecular level if additional control mechanisms are incorporated. One example might be interactions between multiple molecular robots leading to collective behaviour; another might be the ability to read and transform secondary cues on the DNA origami landscape as a means of implementing Turing-universal algorithmic behaviour." This is how nature works. https://lnkd.in/dyH7qBg View in LinkedIn

ROBOT FACTORY. “This robot is part of a nano-factory, a miniature assembly line that can manufacture eight different products." http://science.sciencemag.org/content/345/6198/795 View in LinkedIn

MOLECULAR NANOFACTORY. "At New York University, Hongzhou Gu has also built a DNA robot that walks on a DNA origami landscape. His walker isn’t quite as independent as Lund’s and needs the right triggers to take its steps. But what it sacrifices in autonomy, it makes up for in complexity.” http://science.sciencemag.org/content/345/6198/795 View in LinkedIn
