I'm just going to quote the entire item:
A team of Stanford engineers have created a small computer that can function inside a living cell.That's awesome. I look forward to applications.
According to a report in today's issue of the journal Science, the biological computer can detect disease, send warning of toxic dangers to the cell, and even self-destruct an infected cell if needed.
The computer culminates 10 years of efforts by researchers to create a biological computer, and is the latest step in the field of synthetic biology.
Other things the internal computer can do is engineer small changes like a cell's smell or color, and count cell divisions.
It basically starts to fulfill hopes and dreams in my imagination regarding nanotechnology and supporting biological functions. When I have time, I hope to read more on this, to see whether it can be used for cancer treatment. I wonder whether it's the type of work that they could insert into cells of a living adult.
