Scientists reconstruct a 3.3 billion year old protein and discover an all new biochemical pathway critical to life and hiding in plain sight

We’re just starting to understand how evolution takes advantage of much more than mutations in our DNA.  Everything evolves, from the biochemical pathways to the cellular structures that support them.  Further, some of these structures are incredibly ancient, shared by all life, and still working today. The human body is constructed from four basic building… Continue reading Scientists reconstruct a 3.3 billion year old protein and discover an all new biochemical pathway critical to life and hiding in plain sight

Designing self-replicating cells one gene at a time and solving the mystery of the origins of life

Meet JCVI-syn3A, the world’s first self-reproducing synthetic organism.  This tiny little microbe was designed by trial and error in a lab and is capable of both maintaining its own internal structure and creating copies of itself, just like a real cell.  The implications for medicine and our understanding of ourselves are, needless to say, enormous.… Continue reading Designing self-replicating cells one gene at a time and solving the mystery of the origins of life
