Researchers in the US have developed bacterial computers that can revolutionise genetic research. The research team, including scientists from Missouri Western State University and Davidson and Davidson college in North Carolina, USA, engineered the DNA of Escherichia coli bacteria or E-Coli Bacteria and created bacterial computers capable of solving a classic mathematical problem known as the Hamiltonian path problem. The Hamiltonian path problem asks whether there is a route in a network from a beginning node to an ending node, visiting each node exactly ones. Alternatively, a computer made from millions of bacteria can look at every route simultaneously. The biological world also has other advantages. As time goes by, a bacterial computer will actually increase in power as the bacteria reproduce.
The researchers modified the genetic circuitry of the bacteria e coli bacteria to enable them to find a Hamiltonian path in a three Node graph. Bacteria that successfully solved the problem reported their success by fluorescing both Red and Green, resulting in Yellow colonies. . The second-generation bacterial computers illustrate the feasibility of extending the approach to other computationally challenging math problems. The research extends previous work published last year in the same journal to produce bacterial computers that could solve the Burnt Pancake Problem.
"Our research contributed more than 60 parts to the Registry of Standard Biological Parts, which are available for use by the larger synthetic biology community, including the newly split red fluorescent protein (bacterial protein) and green fluorescent protein genes," said Jordan Baumgardner, recent graduate of Missouri Western and first author of the research paper. "The research provides yet another example of how powerful and dynamic synthetic biology can be. We used synthetic biology to solve mathematical problems; others find applications in medicine, energy and the environment. Synthetic biology has great potential in the real world." Computers are evolving – literally. While the tech world argues netbooks vs. notebooks, synthetic biologists are leaving traditional computers behind altogether. As mentioned above a team of US scientists have engineered bacteria that could solve complex mathematical problems faster than anything made from silicon. In addition to proving the power of bacterial computing, the team have also contributed significantly to the field of synthetic biology. Just as electronic circuits are made from transistors, diodes and other devices, so too are biological circuits. Synthetic biologists have worked together to create the Registry of Standard Biological Parts, and this new research has contributed more than 60 new components to the list. The resulting advance in synthetic biology, according to researchers, hints at the ability of tiny “living computers” to aid in data storage, evolutionary comparisons and even tissue engineering.
You just wait and watch, just you can’t imagine what the world is going to be in the feature...The world of electronics and computing is having fastest growing speed.. Bacterial Computer are the features of computing…
