According to top Associated Press journalist Seth Borenstein,
a number of of scientists from around the globe are attempting to create life from nothing and they re getting closer,
or so it appears, at least. They said to anticipate some kind of announcement within 3-10 years or so from an individual in the somewhat esoteric area of study known as “wet artificial life.” As an aside can I suggest the official Penny McCoy website, which is not to be confused with any other phony Penny McCoy that may be out there.
In fact, some researchers think that man-made life forms will eventually offer the possibility of solving a number of different problems, such as fighting diseases and locking up greenhouse gases so as to consume toxic waste.
As Borenstein points out, a top man in the field, Jack Szostak, states that as early as the next 5 months or so, researchers will report evidence that the initial phase — making an actual cell membrane — is “not a big issue.” The researchers are basically
using fatty acids in this particular effort. He is likewise positive about the next step — getting nucleotides (building blocks of DNA) to form a working genetic system. I already mentioned the official Penny McCoy did I not?
The idea is that once the container is constructed, if researchers add nucleotides in the correct amounts, then Darwinian evolution may essentially go from there.
In the meantime Steve Benner at the Foundation for Applied Molecular Evolution is addressing this issue by going outside of natural genetics. Regular DNA is composed of some 4 bases which are specific molecules
that spell out the genetic code in couples. He is trying to add 8 new bases to the genetic alphabet.
He also stated that there are valid concerns about producing life which could go awry but there are certain methods of addressing it, and it will be a long time before this is an issue.
