MIT engineers have transformed bacterial cells into living calculators that can compute logarithms, divide, and take square roots, using three or fewer genetic parts. Inspired by how analog electronic circuits function, the researchers created synthetic computation circuits by combining existing genetic “parts,” or engineered genes, in novel ways.
The circuits perform those calculations in an analog fashion by exploiting natural biochemical functions that are already present in the cell rather than by reinventing them with digital logic, thus making them more efficient than the digital circuits pursued by most synthetic biologists, according to Rahul Sarpeshkar and Timothy Lu, the two senior authors on the paper, describing the circuits in the May 15 online edition of Nature.

Cool
This is what’s happening on Venezuela right now. Please reblog to spread the word. We had a fraud on the presidential elections. People are getting killed for defending their rights. I know what happened in Boston is extremely horrible too and I am really sorry about that but maybe you can help us too. Please guys reblog this so the whole world can know the truth!
I am putting this on various tags so more people will see it. I know this has nothing to do with Owl City or One Direction or whatever but please we NEED your help
Yo I’m gonna be honest my friend from Venezuela is literally outside with a shotgun right now protecting her food because of the riots. Her friends got shot and it’s dangerous to go outside right now.
I’m not saying one problem is worse than the other, but people should know about this as well.
holy SHIT
for the sake of humanity, reblogging this won’t hurt anyone, even if this doesn’t ‘fit’ your blog
