I am continuing to find articles that show research into the importance of RNA as a major regulating system. This item uncovers the regulation of nerve impulse transmission by RNA. http://www.sciencedaily.com/releases/2009/03/090315091400.htm Discovering DNA and its mechanism of making long strings of protein molecules has unlocked a door into the more intricate area of living processes regulation. RNA has now taken the stage and the various RNA types are revealing a much more complex arrangement than originally imagined. - On the other hand there are other scientific studies that exude an amorphous optimism regarding research into the issue of origin of life. This finding about asteroids is that left-handed amino acids in asteroids are 20% more in number than right-handed. But, in life the 20 essential amino acids are 100% left-handed. From 20% to 100% is a big change, and these researchers are excited! For abiogenesis, it is any straw in the wind. http://www.newscientist.com/article/dn16779-watery-asteroids-may-explain-why-life-is-le...
