The general concept of artificial machines capable of producing copies of themselves dates back at least several hundred years. An early reference is an anecdote regarding the philosopher René Descartes, who suggested to Queen Christina of Sweden that the human body could be regarded as a machine; she responded by pointing to a clock and ordering "see to it that it reproduces offspring."
Currently, xenobots are primarily used as a scientific tool to understand how cells cooperate to build complex bodies during morphogenesis. [1] However, the behavior and biocompatibility of current xenobots suggest several potential applications to which they may be put in the future.
Gray goo (also spelled as grey goo) is a hypothetical global catastrophic scenario involving molecular nanotechnology in which out-of-control self-replicating machines consume all biomass (and perhaps also everything else) on Earth while building many more of themselves, [1] [2] a scenario that has been called ecophagy (literally: "consumption of the environment"). [3]
Douglas Blackiston and Sam KriegmanYou might have missed the debut of the Xenobots last year when the world was falling apart, but they made quite a splash in the science and tech community. These ...
Scientists have created living robots from human cells that can move around in a lab dish and may one day be able to help heal wounds or damaged tissue, a study says.
To this end, Harvester ships are built around mobile factories. Earth-born humans also view the inhabitants of the various colonies to be little more than spare parts. In Earth 2160, the Morphidian Aliens rely on Mantain strain aliens for colonization. Most Mantain-derived aliens can absorb water, then reproduce like a colony of cells.
The book's main scenario proposes that in about a hundred years from now, human brains will be scanned at "fine enough spatial and chemical resolution," and combined with rough models of signal-processing functions of brain cells, "to create a cell-by-cell dynamically executable model of the full brain in artificial hardware, a model whose signal input-output behavior is usefully close to that ...
Scientists on the project believe the living skin could be a key step in creating robots that heal and feel like humans. ... “It may take up to 10 years of research and development before living ...
