A trio of researchers at Emory University has found a way to speed up parallel processing in a DNA computer. In their paper published in the journal Nature Nanotechnology, Selma Piranej, Alisina Bazrafshan and Khalid Salaita ...
One fundamental question in the field of the Origin of Life is how the first molecules of DNA replicated and evolved on the primordial Earth, more than 4 billion years ago. Before the emergence of the first cells or any other ...
