First artificial life ‘within months’?

Friday, June 29th, 2007

Reported today in the Telegraph UK:

Scientists could create the first new form of artificial life within months after a landmark breakthrough in which they turned one bacterium into another.
Craig Venter likened the process to ‘changing a Macintosh computer into a PC by inserting a new piece of software’.
In a development that has triggered unease and excitement […]

Remarks on Chu-Ho 2006/2007

Sunday, June 17th, 2007

The recent paper by Chu and Ho prompt me to remark on both of their papers. I find numerous errors which void their argument and I discuss additional points.
The original central complaint in Chu-Ho 2006, section 5 [1]:

The problem of this becomes clear when one attempts to recover information about the mapping implemented by the component […]

MIT Artificial Life summer issue - Chu-Ho revisited

Thursday, June 14th, 2007

The summer 2007 issue of Artificial Life is now available. As I previously mentioned, this issue contains three papers relevant to Rosen. They all revolve around the 2006 paper by Chu and Ho:

“A Living System Must Have Noncomputable Models” by A.H. Louie

Abstract: “Chu and Ho’s recent article in Artificial Life is riddled with errors. In […]

A Wiki for Rosennean Complexity

Wednesday, June 13th, 2007

An announcement from Jeff Prideaux on the ROSEN and ROSEN-L forums:
I’ve created an interactive wiki website www.metabolismrepair.com where the community of Rosennean scholars can participate in providing content about Rosennean complexity.  Currently, the wiki is just an empty shell (no content).  I would like to invite everyone with an interest in Rosennean complexity to register at […]

A Metaphor between Modeling Relations

Sunday, June 10th, 2007

One of the fundamental questions in quantum mechanics concerns the interpretation of the QM formalism: what does QM “say” about the material world?  Do the probability distributions in QM reflect corresponding innate properties in the material quantum world, or do they reflect only uncertainties in our state of knowledge about the material quantum world? In […]
