More Reasons Why DNA Is Perfect for Coding
October 5, 2006
Scientists at Vanderbilt University may have been trying to explain chemical evolution, but hit on another reason DNA is the ideal molecule for carrying genetic information (see also Science Daily).  They tweaked the sugar molecule on the DNA backbone and got an unwieldy, haphazard, writhing ribbon of a molecule, unsuitable for bonding genetic code or […]

Paper View:  Evolutionists Augur Genes for Tales of Eyes, Hearts, Brains
September 29, 2006
The Sept. 29 issue of Science includes a special section on evolutionary genetics, beginning with an overview by Barbara R. Jasny, Elizabeth Pennisi and John Travis entitled “Genomic Tales.”1  Our organs tell stories.  A pathologist, for example, can look at a lung and recognize a lifetime of toiling in a mine.  Our genes tell stories, […]

Genetic Toolkit Manages Dangerous Tools with Safety Switch and Lockbox
September 19, 2006
Laymen appreciate scientists who can express complex concepts in everyday terms.  Here’s a good example from the Wistar Institute: Around the home, regularly used tools are generally kept close at hand: a can opener in a kitchen drawer, a broom in the hall closet.  Less frequently used tools are more likely to be stored in […]

What’s Inside a Spore?  Nanotechnology
September 17, 2006
The spores that are emitted from fungi and ferns are so tiny, the appear like dust in the wind.  Who would have ever thought such specks could exhibit nano-technological wonders like scientists have found recently: Evapo-Motors:  Scientists at U of Michigan were intrigued by how ferns turn the power of evaporation into launching pads.  The […]

Voles Throw Evolutionary Genetics Into Disarray
September 16, 2006
What is it with voles?  These little gopher-like furballs with beady eyes, short tails and tiny ears are giving evolutionary geneticists fits.  A press release from Purdue University states, “Purdue University research has shown that the vole, a mouselike rodent, is not only the fastest evolving mammal, but also harbors a number of puzzling genetic […]

Another Rotary Machine Found in Bacteria
September 13, 2006
A molecular “garbage disposer” in the cell membrane bearing some resemblance to the rotating motor ATP synthase has been described in Nature.1  This machine, called AcrB, expels toxins from the cytoplasm through the cell membrane to the outside.  Like ATP synthase, it has three active sites at one end where the binding occurs, and it […]

Plant Protection: A Modern Medieval Castle Story
September 13, 2006
Vigilant guards stand at the gates.  In times of peace, they let down the drawbridge, and the townspeople carry on their trade.  Farmers bring in their crops for the marketplace, and local craftsmen and pedlars keep the local economy bustling.  Yet the sentries maintain a watchful eye, aware that numerous interlopers are about.  Aliens constantly […]

Do Mammals Depend on Virus Help?
September 12, 2006
Researchers found that sheep depend on a retrovirus to become pregnant.  Retroviruses (those that can insert themselves into a genome of a host cell) include the dreaded HIV and generally have a bad reputation.  Remnant retroviruses are prevalent in many animal species and have been considered a class of “junk DNA,” having mutated away their […]

Is the Fruit from Darwin’s Tree Edible?
September 8, 2006
Darwin’s “Tree of Life” fruit stand found an upbeat salesman in John Roach at National Geographic this week.  In his update on the “Assembling the Tree of Life” (AToL) project, he reported cheerfully that “New cures, supercrops, and secrets of evolution may emerge from the fast-growing branches of the ‘Tree of Life,’ scientists say.”   […]

Flagellar Swimmers Attain Mechanical Nirvana
September 6, 2006
Those little germs that scientists love, E. coli – you know, the ones with the flagella that intelligent-design folk get all excited about – well, they move through the water pretty efficiently with those high-tech outboard motors of theirs.  Some Pennsylvania physicists reporting in PNAS1 measured the “swimming efficiency of bacterium Escherichia coli” and concluded, […]

Yoke Up Those Bacteria
September 6, 2006
My, how history repeats itself – often in unexpected ways.  In ancient times, our ancestors got the heavy work done by hitching oxen, horses or slaves (like Samson, see pictures 1 and 2) to a harness and making them turn a grinding wheel.  The same principle is now on the cutting edge of modern applied […]

Another Flagellum Excites Scientists
September 1, 2006
“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 […]

There’s a little Neanderthal in a lot of us, claims The Telegraph.  This is bad news and good news: People who have large noses, a stocky build and a beetle brow may indeed be a little Neanderthal, according to a genetic study.  But the good news is that other research concludes that Neanderthals were much […]

Chimp-Human Genes Evolved Much Faster Than Expected
August 22, 2006
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?
August 4, 2006
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 […]
