Scientists Attempting to Create Simple Life Form
derubergeek writes "The Washington Post is reporting on an apparently credible project to create a simple life form in a petri dish. The goal is two-fold: 1) to actually create a unique life form essentially from scratch and (more importantly) 2) to extensively analyze and model the entire biology of this critter. Exciting and scary at the same time. From the article, it sounds as if they are quite wary of their project and fascinated at the same time. I usually refer to that sensation as 'That little voice that I should have listened to...'" There's also a NY Times article.
No one ever brings these [moral] arguments up in chemistry, or physics, or math
I think Einstein would have disagreed with you.
An excellent overview of minimum-gene-set research is here...
The hypothesis that "chemistry explains all of life" is nearly universal in science, yet is not fully proven yet (though I believe it). The ultimate test of the chemistry hypothesis is be to construct life from inert chemicals off the shelf. The closest one got was the constuction of a polio virus from regeants earlier this year. The virus appeared viable, but was about a thousand times less potent than its natural version. The simplest life form, as described in this article, is about 20-50 times more complicated than a virus in terms of genes and chemicals (proteins, sugars, others).
The alternative hypothesis is "neo-vitalism" or that is some mysterious substance or force outside of pure chemistry. This was the prevailing hypothesis until well into the 19th century. But it keeps on reappearing in more "scientific" forms today. One statement is the "only living material can produce living matter", even though you can fully explain all the chemistry, physics, and genetics. Another version callled "morphogensis" is that there are "patterns" in lving matter that are transmitted from ancestor to descendent. Yet another version, championed by physicist Roger Penrose is that there is secret unknown physics involved (clarification: he specificiation is attributing human consciousness to a new form of quantum interaction). Still another variation is "holism" or "emergism" which states the totally is greater than the sum of the parts, i.e. a reductionistic explanation is necessarily incomplete.
Note the relation of life to matter is a very old philosophical problem. The ancient Greek story of Pygmalian, the medival Golem, and the 186 year old Frankenstein novel all addressed this issue.
An auxilary problem is artificial intelligence. Its seem obvious that this can be done by us computer geeks. But 55 years of effort have had disappointing results. Some people use similar arguments against artificial life against artificial intelligence.
