Fine-Tuning Found in Life’s Rotary Engine
August 4, 2010
The universal energy currency in living things is ATP.  To produce the vast quantities of this molecule required by life 24 x 7, cells employ banks of rotary engines called ATP Synthase, which we have reported on previously in these pages many times.  ATP synthase has become somewhat of a mascot of intelligent design, because […]

Cell Regulation Doesn’t Just Happen
August 2, 2010
Scientists are finding that it’s not just having the right parts that makes a body go; it’s having those parts controlled by the right regulators.  Recent stories make the case with their headlines: “‘Guardian of the Genome’: Protein Helps Prevent Damaged DNA in Yeast,” announced Science Daily.  “Scientists find gas pedal – and brake – […]

Electricity Forms Your Heart
July 31, 2010
Did you know your heart is an electrical appliance?  That’s right.  Currents of electrical ions are vital to its function as a contractile organ.  Now, researchers at the University of California have found another thing electricity does for your heart: it guides the developing heart into the proper shape.  This is a key study showing […]

Darwinists Get Sexy
July 13, 2010
The origin of sex titillates many evolutionary biologists.  On the one hand, animals and plants have such interesting ways of getting together.  But on the other hand, sex seems too costly to have originated by natural selection.  Some recent articles provide new evolutionary speculations on the origin of sex – but simultaneously undermine previous speculations. […]

Bacteria Too Complex To Be Primitive Eukaryote Ancestors
July 12, 2010
In the search for the most primitive life forms on earth, bacteria would certainly make the list.  They are tiny, one-celled, and have small genomes.  Why, then, did Patrick Forterre and Simonetta Gribaldo of the Pasteur Institute say in PNAS,1 “we should definitely stop thinking of bacteria in terms of simple ‘lower’ organisms”?  For the […]

Proteins Fold Who Knows How
July 9, 2010
One of the biggest mysteries remaining in cell biology is how proteins fold.  Proteins start out as chains of amino acids (polypeptides) as they exit the ribosome.  Most of them spontaneously fold into their “native” three-dimensional structures, where they will go to work as enzymes, structural materials or other key players in cell life.  About […]

Productive Science Imitates Nature
July 7, 2010
Examples continue to accumulate that some of the most interesting and fruitful science projects involve copying design principles found in nature.  This “biomimetics” approach not only pleases the consumers who can look forward to greener, cheaper, better products, but leads to deeper understandings of nature’s workings. Gecko adhesives:  PhysOrg published a story on the ongoing […]

Your Inner Locomotive Revealed
July 6, 2010
Visualize an old locomotive train roaring down the tracks.  One of the characteristic images that surely comes to mind is the oscillating motion of the coupling rods on the wheels.  The long rods that connected the wheels provided a way to convert heat energy from the steam into mechanical energy (example video on YouTube).  It […]

Tibetans Evolved Altitude Tolerance in 3,000 Years
July 3, 2010
Tibetans and other peoples who live at high altitudes possess a remarkable tolerance to the thin atmosphere.  Now, scientists at UC Berkeley have identified some 30 genes related to oxygen regulation that differ in Tibetans from Han Chinese.  Since those tribes are thought to have diverged 3,000 years ago, natural selection for these changes must […]

Heal the Blind with Stem Cells
June 30, 2010
Have you heard that some cases of corneal blindness can be cured by stem cells #– from the person’s own eyes?  New Scientist recounted some recent successes for victims blinded in one eye by burns or acid.  Stem cells taken from the limbus, a disk surrounding the iris, and transplanted onto the damaged cornea, were […]

Farm Algae for Energy
June 29, 2010
June 29, 2010 — Why manufacture fuels when microbes can do it faster, better and cheaper?  Researchers at the University of Cambridge are wiring electrodes to algae to produce “green energy” – solar-powered fuel that is carbon-neutral, “cheaper to produce, self-repairing, self-replicating, biodegradable and much more sustainable – real green energy.”     The team […]

Fish Feet: Can Evolution Add by Subtraction?
June 26, 2010
How did fish grow feet?  One would think that feet require adding a lot of new parts: bones, muscles, nerves, blood vessels, and additional supporting tissues.  Each of those would require genetic instructions and changes to embryonic development.  One evolutionist, however, feels that switching genes off paved the way to the invasion of land.  The […]

The RNA Code: Pseudogenes Functional, Help Prevent Cancer
June 24, 2010
A surprising function has been discovered for a “pseudogene” – an apparently mutated copy of a regular gene that till recently was thought to be genetic junk.  This pseudogene, reported in Nature today,1 not only has a function unrelated to the production of proteins, but a function that could save your life.  It is part […]

Flagellum Replaces Parts on the Fly
June 12, 2010
A new study appears to show that the bacterial flagellum, a molecular rotary motor that has become iconic of the intelligent design movement, can repair parts of its rotor while it is rotating.  The results of the study by Oxford University were published in PNAS,1 and were also the focus of a Commentary in PNAS […]

Not Lamarck Again
June 11, 2010
Remember Lamarck?  He was the pre-Darwin evolutionist whose theories we were all taught were overthrown by Darwin’s superior theory of natural selection.  Lamarck’s theory of “inheritance of acquired characteristics” was shown to be demonstrably false by the dramatic experiments of Weismann, right?  It was never really so clear-cut as that, as evolutionary historians know, but […]
