Our new Indie Games subforum is now open for business in G&T. Go and check it out, you might land a code for a free game. If you're developing an indie game and want to post about it, follow these directions. If you don't, he'll break your legs! Hahaha! Seriously though.
Our rules have been updated and given their own forum. Go and look at them! They are nice, and there may be new ones that you didn't know about! Hooray for rules! Hooray for The System! Hooray for Conforming!
[History On!] First Artificial DNA Base Synthesis?
We describe a new class of DNA-like oligomers made exclusively of nonnatural, stable C-nucleosides. The nucleosides comprise four types of nonnatural bases attached to a deoxyribose through an acetylene bond with the β-configuration. The artificial DNA forms right-handed duplexes and triplexes with the complementary artificial DNA. The hybridization occurs spontaneously and sequence-selectively, and the resulting duplexes have thermal stabilities very close to those of natural duplexes. The artificial DNA might be applied to a future extracellular genetic system with information storage and amplifiable abilities.
This paper was first submitted in February, but I hadn't heard about it until now. Absolutely incredible. Even more so that this should occur in the same year as the Memristor's physical inception.
Fleshing out for Mods (please don't hurt me Elki! ) :
What are the implications of this do you think, in terms of humanity beginning to steer the course of it's own evolution. One far-reaching possibility of this is the direct encoding of data into newly-created organisms, and also lifeforms with triple helix DNA. Does mankind have the right to be doing this?
