Autopoiesis was originally presented as a system description that was said to define and explain the nature of living systems. A canonical example of an autopoietic system is the biological cell. The eukaryotic cell, for example, is made of various biochemical components such as nucleic acids and proteins, and is organized into bounded structures such as the cell nucleus, various organelles, a cell membrane and cytoskeleton. These structures, based on an external flow of molecules and energy, produce the components which, in turn, continue to maintain the organized bounded structure that gives rise to these components (not unlike a wave propagating through a medium). An autopoietic system is to be contrasted with an allopoietic system, such as a car factory, which uses raw materials (components) to generate a car (an organized structure) which is something other than itself (the factory). However, if the system is extended from the factory to include components in the factorys "environment", ...
The production of artificial life is supposedly just around the corner. But ever since the famous 1953 Miller and Urey experiment failed to spark life in the laboratory just from chemicals, that corner has proven painstakingly long to get around.. In August, biologist Craig Venter of the J. Craig Venter Institute in Maryland was reported as predicting that artificial life is just months away.1 His team had cloned, added to, and modified the DNA of a "simple" bacterium called Mycoplasma mycoides (a prokaryote).. The complex procedure they used involved taking plasmid sequences from yeast (eukaryote) and adding them to the Mycoplasma chromosome. This engineered chromosome was swapped for the yeast genome, making a reproducing, yeast-like bacterium. This series of steps promises to expedite the transfer of an artificially synthesized genome into a cell. Researcher Sanjay Vashee said that his team had achieved "a major advance in our effort to create a synthetic cell."1. A number of questions, ...

Introduction. Artificial Life (AL) is a rather new scientific discipline, which didnt really get going until the 1980s.1 Unlike biology, it seeks to study life not out in nature or in the laboratory, but in the computer.2 AL seeks to mimic life mathematically, and especially to generate known features of life from basic principles (Langton, 1989b, pp 2-5). Some of the more gung-ho specialists in AL see themselves as creating life in the electronic medium (Ray, 1994, p 180); others think they are only imitating it (Harnad, 1994, pp 544-49). Without addressing this particular question, theists can at least agree that life does not have to be manifested in biochemistry.. Those who believe in metaphysical naturalism -- that "the Cosmos is all that is, or ever was, or ever will be" -- must presume a purely non-supernatural origin and development of life, unguided by any mind. For metaphysical naturalism, no other kind of causality really exists. Theists, by contrast, believe that a mind -- God -- is ...
In a major step toward creating artificial life, U.S. researchers have developed a living organism that incorporates both natural and artificial DNA and is capable of creating entirely new, synthetic proteins.
Scientists have taken a major step toward creating the first ever artificial life form by synthetically reproducing the DNA of a bacteria, according to a study published Thursday.
Pygmy Growth Curves: A Comparative Approach. In most human populations, a large portion of variance in stature can be accounted for by nutritional status . Nutritional studies worldwide have shown the predictability of the growth response to stress-societies with very high caloric budgets show significant secular trends toward earlier growth cessation, faster body growth, and increased size, whereas populations under nutritional stress normally reduce growth rates, delay growth cessation, and show smaller adult body sizes . To test whether the growth pattern of pygmies is characteristic of nutritionally impaired populations, growth curves were constructed for the Aeta and compared with those for the Biaka and Agta pygmies and compared with the lower percentiles of the U.S. growth distribution, representing undernourished individuals who grow only to average adult pygmy size (women HEIGHT = 140 cm, corresponding to the 0.01th percentile of the U.S. distribution). The curves show that pygmies ...
What makes a living system a living system? What kind of biological phenomenon is the phenomenon of cognition? These two questions have been frequently considered, but, in this volume, the authors, Humberto Maturana and Francisco Varela, consider them as concrete biological questions. Their analysis is bold and provocative, for the authors have constructed a systematic…
This is a bold, brilliant, provocative and puzzling work. It demands a radical shift in standpoint, an almost paradoxical posture in which living systems are described in terms of what lies outside th
Thankfully, Romesberg and his team have no intention of using their research to provoke some kind of explosion of new, hybrid life forms. As Romesberg told Reuters, his X and Y nucleotide bases cant bond with DNAs natural bases, nor can these semi-synthetic organisms (SSOs) survive outside a laboratory setting. "They cant escape," Romesberg said. "Theres no Jurassic Park scenario.". Still, as University of Waterloo associate professor Brian Ingalls told Futurism, we must be cautious when dealing with the manipulation of life.. "Based on our knowledge of how life works (at the molecular level and above), its not worthwhile to attempt a distinction between natural and artificial," he said. "We can, however, distinguish new from old, and there we should be concerned about the potential for new organisms to disrupt existing ecosystems.". As Ingalls noted, Romesbergs study is designed in such a way as to prevent such disruption. "New organisms whose molecular mechanisms are sufficiently ...

If you start giving these cells the power to sense their surroundings as well (maybe to predict the best drug to produce) you get very close to something that can be called life. Its artificial life, life designed exclusively to serve the humans that use it, but life non-the-less. At this stage, it becomes almost meaningless to talk about life and non-life as separate boxes, and instead they become a gradiant, a sliding scale between the living and the dead. This is something that is starting to be appreciated even now when considering things like viruss, or prions. A prion is an infectious protein element, with no DNA or cell wall yet it is capible of replicating and evolving (and consequently sticking two fingers up to Dawkins a bit). If a small piece of twisted protein has a passing claim to life the definition of what life actually is starts to become somewhat hazy. And scientists have made viruss in the lab, creating what could potentially be classified as living organisms from ...

Ampelosaurus (/ˌæmpɪloʊˈsɔːrəs/ AM-pi-loh-SOR-əs; meaning "vine lizard") is a titanosaurian sauropod dinosaur hailing from the Late Cretaceous Period of what is now Europe. Its type species is A. atacis, named by Le Loeuff in 1995. A possible unnamed species has given Ampelosaurus an age reaching to the latest Cretaceous, from about 70 to 66 million years ago. Like most sauropods, it would have had a long neck and tail but it also carried armor in the form of osteoderms. Over 500 bones have been assigned to Ampelosaurus and all but the braincase (assigned to A. sp.) has been assigned to A. atacis. They are assigned to the same species because all the differences in the limb proportions have been linked to individual variation. A. atacis is known from a few, well-preserved teeth and some cranial material. A right scapula was discovered associated with a coracoid. The blade of the scapula, contrary to most titanosaurs, is triangular. The blade narrows at one end instead of showing an ...

Robots can exhibit life like behavior but are, according to traditional definitions, not alive. Current robot users are confronted with an ambiguous entity and it is important to understand the users perception of these robots. This study analyses if a robot s intelligence and its agreeableness influences its perceived animacy. The robot s animacy was measured, amongst other measurements, by the users hesitation to switch it off. The results show that participants hesitated three times as long to switch off an agreeable and intelligent robot as compared to a non agreeable and unintelligent robot. The robots intelligence and had a significant influence on its perceived animacy. Our results suggest that interactive robots should be intelligent and exhibit an agreeable attitude to maximize its perceived animacy.
Jozwik et al. (2016) tested the explanatory power of a feature-based model for similarity judgments (and for neural representation) that also included a number of shape features. As similarity judgments typically produce a fundamental distinction between animate and inanimate objects, the authors implicitly tested the role of shape features for animacy categorizations. The model contained 120 feature dimensions that were generated by human observers and included shape features (e.g., curved, cylindrical, spiky), but also object parts (e.g., horns, wings, hand/fingers; about two-thirds of the dimensions), objects (e.g., tree, waterfall, leaves), colors (e.g., green, brown, gray), materials/textures (e.g., fur, metallic, wet/water), and others. On a set of 96 images of familiar objects, the model predicted neural representation in IT with equal accuracy as a categorical labeling model, suggesting that those features "serve as stepping stones toward a representation that emphasizes categorical ...

Exploring perception using computation and artificial life.. While all brains are made from the same biological stuff, their diversity in structure is phenomenal. And yet, all animals as diverse as bees and humans evolved to solve the same visual puzzles, and even probably as a consequence see the same illusions. A critical aim of our research is to understand what is common between such divergent systems. Only when we know this answer will we be able to understand the principle by which the brain any brain makes sense of the world. If such a common principle exists, then itll be best described at the level of mathematics (computation more generally), because this level of explanation is mute to the actual structure of the system of interest in the same way that mathematical theories of evolution transcend the structure thats evolving. On this page, we feature our work that is attempting to discover how all networks natural or artificial resolve the inherent uncertainty of sensory information, ...
