A Second Code Controls the DNA Code

More has been discovered about the histone or nucleosome code (see 02/17/2004), a second genetic code independent of the DNA genetic sequence that directs the formation of proteins.  The New York Times (see also Science Daily) reported on work by scientists at Northwestern University who found that the wrapping of DNA around nucleosomes (made of […]

Cell Backup Systems Challenge Evolution, Show Design Principles

Has an intelligent design paper been published in the Proceedings of the National Academy of Sciences?1  Read the abstract and decide whether this research supports Darwinism or design: Functional redundancies, generated by gene duplications, are highly widespread throughout all known genomes.  One consequence of these redundancies is a tremendous increase to the robustness of organisms […]

Cell Untangles Its Own DNA

DNA is packed like spaghetti in a basketball (07/28/2004), but must constantly be accessed by transcribers, duplicators and other molecular machines.  Scientists at the Karolinska Institute, according to EurekAlert, have found a complex of protein machines that know how to untangle DNA.  Machines that can keep DNA from separating too early (cohesins) and keep DNA […]

Genetic Code Began by Lamarckian Evolution

It takes guts to tackle the origin of the genetic code from a naturalist perspective.  It also takes guts to resurrect Lamarck in the age of Darwin.  Carl Woese and colleagues tried a new hypothesis in PNAS1 that boldly goes headlong into both challenges.  To preserve a natural explanation for the genetic code, they felt […]

Stem Cells Protect Against Defective Copies

The Pasteur Institute (see Louis Pasteur) has found evidence supporting a controversial theory known as the “immortal DNA” theory.  According to News-Medical.Net, researchers at the institute believe that stem cells keep the best copies and allow only defective ones to differentiate and specialize.  If so, this may be another mechanism for minimizing the effects of […]

Evolutionists Find Pegasus in the Gene Epic

When you conjure with genes, you never know what might appear.  Japanese scientists, publishing in PNAS,1 tried to find evolution in mammalian retroposons and found an unexpected relationship.  New Scientist explains: “You could call it a batty idea, but bats seem to be more closely related to horses than cows are.”     “Despite the […]

Science Reporters Spin Spider Web Data Into Evolutionary Program

A spider was found perfectly preserved in amber (fossil tree sap), complete with its web and prey.  It is identical to modern spiders.  Isn’t evolution amazing?     If you just experienced a software crash, there must be something wrong with your BIOS.  All the news media ran that program just fine.  A patch is […]

Rubisco “Highly Tuned” for Fixing Atmospheric Carbon

Rubisco sounds like a brand of cracker or something, but it’s actually an air cleaner your life depends on.  It’s an enzyme that fixes atmospheric carbon for use by photosynthetic microbes and plants.  In doing so, it sweeps the planet of excess carbon dioxide – the greenhouse gas implicated in discussions of global warming – […]

More Darwinian Assumptions Shot Down

Here are two articles that appear to kick out some once-solid props from evolutionary theory.  Readers are encouraged to get the details from the original papers, listed in the footnotes. Environmental Impotence:  Many evolutionists have claimed that the environment produces strong selection effects.  Indeed, the fitness landscape itself evolves, carrying with it the constraints driving […]

When Evolutionist Rebukes Evolutionist, Watch Out

“Faithful are the wounds of a friend,” Solomon said.  Sometimes comrades need to rein in their own when they stray too far.  Kenneth M. Weiss and Anne V. Buchanan (Dept. of Anthropology, Penn State) had some stern rebukes for Nicholas Wade, who was just trying to praise Darwin in his new book Before the Dawn: […]

Eukaryote Evolution Proceeded from Complex to Simple

As if reprimanding simpletons, three scientists writing in Science1 preached that the old picture of evolution from simple to complex is simplistic.  This is particularly true, they claim, for the story that eukaryotes were born from a blessed union.  “Data from many sources,” they counter, “give no direct evidence that eukaryotes evolved by genome fusion […]

Plant Hula-Hoop Railroads Build Cell Walls

Solving a long-standing mystery about how plants build cell walls, Stanford scientists imaged molecular machines traveling along hoop-shaped rings around the inside of the cell.  Publishing in Science, Paradez, Somerville and Ehrhardt proved that cellulose synthase (CESA), a machine that manufactures cellulose composed of six subunits arranged in rosettes, rides like a rail car on […]

Evolutionary Trees “Positively Misleading”

According to an article in PLoS Genetics,1 there is a fundamental flaw in the way species trees are inferred from gene trees using molecular genetics that is guaranteed to produce erroneous results: Because of the stochastic way in which lineages sort during speciation, gene trees may differ in topology from each other and from species […]

Protein Dressing Room Has Electronic Walls

Properly folded proteins are essential to all of life.  When a polypeptide, or chain of amino acids, emerges from the ribosome translation factory on its way to becoming a protein, it looks like a useless, shapeless piece of string.  It cannot perform its function till folded into a precise, compact shape particular for its job.  […]

Hobbit Man, Neanderthal Man Further Scrutinized

The positions of two alleged human ancestors in the family tree is becoming clearer, or murkier, depending on whom you ask.  This illustrates the uncertainty and disparity of opinions in this field. Hobbit workshop:  Regarding the diminutive skeletons dubbed Homo floresiensis found in Indonesia, opinions seems to be condensing around the idea they were true […]
