Was four-stranded, ‘quadruple helix’ DNA designed or mutated?
| January 21, 2013 | Posted by DLH under Biophysics, Cell biology, Genetics, Human evolution, Intelligent Design |
‘Quadruple helix’ DNA seen in human cells Balasubramanian’s group has been pursuing a four-stranded version of the molecule (DNA) that scientists have produced in the test tube now for a number of years. It is called the G-quadruplex. The “G” refers to guanine, one of the four chemical groups, or “bases”, that hold DNA together… more
A Designed Object’s Entropy Must Increase for Its Design Complexity to Increase – Part 2
| September 5, 2012 | Posted by scordova under Biophysics, Comp. Sci. / Eng., Complex Specified Information, ID Foundations, Informatics, Physics, Self-Org. Theory |
In order for a biological system to have more biological complexity, it often requires a substantial increase in thermodynamic entropy, not a reduction of it, contrary to many intuitions among creationists and IDists. This essay is part II of a series that began with Part 1 The physicist Fred Hoyle famously said: The chance that… more
A Designed Object’s Entropy Must Increase for Its Design Complexity to Increase – Part 1
| September 4, 2012 | Posted by scordova under Biophysics, Comp. Sci. / Eng., Complex Specified Information, ID Foundations, Informatics, Physics, Self-Org. Theory |
The common belief is that adding disorder to a designed object will destroy the design (like a tornado passing through a city, to paraphrase Hoyle). Now if increasing entropy implies increasing disorder, creationists will often reason that “increasing entropy of an object will tend to destroy its design”. This essay will argue mathematically that this… more
Does the Constructal Law Give Evidence of Design?
| July 17, 2012 | Posted by johnnyb under Biophysics, Books of interest, Engineering, Intelligent Design, Philosophy, Physics, Spirituality, Video |
In Bejan’s “Design in Nature”, Bejan promotes what he calls the “constructal law,” which states, “For a finite-size system to persist in time (to live), it must evolve in such a way that it provides easier access to the imposed currents that flow through it.” Bejan has denied that this relates at all to any… more
2nd Law of Thermodynamics — an argument Creationists and ID Proponents should NOT use
| July 4, 2012 | Posted by scordova under Biophysics, ID Foundations, Intelligent Design, Physics, Science |
ID proponents and creationists should not use the 2nd Law of Thermodynamics to support ID. Appropriate for Independence Day in the USA is my declaration of independence and disavowal of 2nd Law arguments in support of ID and creation theory. Any student of statistical mechanics and thermodynamics will likely find Granville Sewell’s argument and similar… more
Broadband Beasts
| May 7, 2012 | Posted by PaV under Biophysics, Intelligent Design |
In today’s PhysOrg highlights, we hear about how yeast cells are able to communicate with one another via biochemical means. Using mathematical means to separate “noise” from information pathways. These beasts have “broadband”! “The mathematics provides variance decomposition techniques for dynamic systems,” said Dr Bowsher. “We were able to make rigorous connections between the concept… more
First Gene: Functional sequence complexity (FSC) found in biopolymers as well as human languages and computer code
| November 30, 2011 | Posted by News under Biophysics, Intelligent Design, News |
Clearly, FSC can be found in human languages and carefully designed computer code, but the measure we propose in this paper reveals that it is also found in biopolymers. more
