> E. Coli: A lab strain of the E. Coli bacterium use for research has 4,460 genes.
> SpudCell: This new synthetic cell only has 36 genes.
Wow, so little genes even compared to E. Coli! Things like this make me wonder what the minimum number of genes is required to maintain functionality for cells in species we have all around us. There isn't much evolutionary pressure to do the genetic equivalent of dead code removal (See: https://en.wikipedia.org/wiki/Equisetum_arvense) besides the ability to copy the genes.
My other first impression is the potential similarities to alien contact. What if these cells, once given the ability to reproduce autonomously, become widespread around the globe, with no way for our, and other species', immune systems to prevent their consumption of biomatter, or whatever is made to be their "food".

“ Scientists hope synthetic cells can tell them things about life that natural cells cannot, including such basic questions as how many genes are necessary for a minimal form of life.
But synthetic cells also might someday be engineered to do things that natural cells can’t, like making new kinds of medicine or drawing large amounts of carbon dioxide from the atmosphere. In theory, engineered SpudCells might produce a vast range of proteins that natural cells cannot be coaxed to make, or even toxic chemicals like rocket fuel.
Now, “we can think about doing chemistry that we’re barely getting our heads around,” Dr. Glass said.”
