Scientists have created the first biosynthetic dual-core cellular computer


Scientists have long been studying the possibility of creating a cellular nanocomputer that would work through gene switches. The basis of conventional devices are logical chains that can be built using protein switches.

According to Swiss scientists, they managed to create the first kind of computer, consisting of cells. Instead, the nucleus is an altered Cas9 protein, which can regulate the expression of a particular gene in response to a signal fed through RNA chains. As a result, a given protein is created that allows programming of the chains inside the cells, both in response to incoming and outgoing signals.

After creating a model for reprogramming proteins, scientists created a biological dual-core processor by combining two cores into a cell. For this, engineers used gene modifiers from two different bacteria.

In the future, scientists intend to explore the possibility of using such biosynthetic computers.
