(Our Tech Blog) Researchers at the California Institute of Technology (Caltech) claim they have managed to create a network of artificial
A postdoctoral scholar, Lulu Qian and colleagues describe the process of molecular systems can produce behavior like the brain in a paper published on July 21.
Qian said that the researchers made four neurons are composed of 112 different DNA strands. Much when compared with human brain tissue that has 100 thousand neurons.
Rudimentary neural network is able to work on a simple input-output mechanism, called strand-displacement cascade. Basically, the synthesized DNA strands floating on water and join to the strand that has a structure complementary base pairs, which then creates an input. When fusion occurs, a strand of DNA is released and creates the output.
As quoted from beritateknologi.com, the last experiment, the researchers tried to train the neural network is in the game contains questions with a yes and no.
One researcher put the strands of DNA which represents a series of incomplete answers to the test tube, which had previously contained the DNA Network. Then the network will provide the answer by using the fluorescent signal.
Of the 27 attempts, DNA 'brain' with the correct answer. Parties Caltech said that DNA networks have the ability to think, albeit very low. In the game, to be able to answer correctly, the network of DNA takes 8 hours, and each strand of DNA can only be used once only.
