Another Flagellum Excites Scientists

“The bacterial flagellar motor excites considerable interest because of the ordered expression of its genes, its regulated self-assembly, the complex interactions of its many proteins, and its startling mechanical abilities,” begins a paper in Nature by three Caltech scientists.1  They performed electron cryotomography imaging on the flagella of Triponema primita, a different critter with a […]

Chimp-Human Genes Evolved Much Faster Than Expected

It’s been all over the news lately – human DNA shows surprisingly divergent regions from chimpanzee counterparts.  The Houston Chronicle, for instance, summarizes the find: Searching across the four genomes, the team looked for regions of DNA about 100 letters long that had made the biggest leaps. One, they found, had changed nearly twice as […]

How Useful Is Evolutionary Theory to Biology?

A favorite quote by evolutionists is the line by Theodosius Dobzhansky, “Nothing in biology makes sense except in the light of evolution.”  Why, then, do so many biological papers fail to mention evolution at all?  Indeed, many employ design language, sometimes with a sense of awe.  Here are more recent examples in which the E […]

Team Returns Pseudogene to Junkpile to Counter ID Claim

An earlier claim that a pseudogene has a function (see 05/01/2003 story) has been debunked by a team of scientists reporting in PNAS.1  Their reanalysis of the claim made in 2003 “invalidates the data upon which the pseudogene trans-regulation model is based and therefore strongly supports the view that mammalian pseudogenes are evolutionary relics.”  The […]

Bacteria Rule the World – Benevolently

We should love bacteria, not annihilate them.  Bacteria are our friends, according to Dianne K. Newman of Caltech:1 As a microbiologist, I’m appalled when I go to buy soap or dishwashing detergent, because these days it’s hard to find anything that doesn’t say ‘antibacterial’ on it…. It’s a commonly held fallacy that all bacteria are […]

Self-Correcting RNA: Is It a Missing Link?

A team of Russian scientists at Rutgers discovered a remarkable phenomenon: RNA that proofreads itself during its own synthesis.  The work was reported in Science1: “We show that during transcription elongation, the hydrolytic reaction stimulated by misincorporated nucleotides proofreads most of the misincorporation events and thus serves as an intrinsic mechanism of transcription fidelity.”  It […]

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 – […]

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: […]
