Fossil Frog-amander Claimed to Be Missing Link
May 28, 2008
It looks like a frog with four equal legs and a tail; is it the ancestor of frogs and amphibians?  It depends on whether you read the original paper or the popular press.     Live Science writer Jeanna Brynner is absolutely certain this puts a feather in Darwin’s cap: “the creature represents a transitional […]

Animals Outsmart Scientists
May 15, 2008
In science, long-standing beliefs are often challenged by new evidence.  Several recent findings not only show animals to be more remarkable than thought, they pose some new questions for evolutionists. Slothlessness:  Sleeping almost all day, the sloth is the epitome of laziness in the animal kingdom.  Or is it?  The BBC News now tells us […]

Sweet Solutions from Nature
April 29, 2008
Human engineers continue to look at plants and animals for inspiration.  Biomimetics – the imitation of biology for design technology – shows no sign of running out of ideas. Sweet gas:  A spoonful of sugar in the gas tank?  Science Daily reported on progress in converting plant sugars into clean-burning hydrogen – using biological enzymes.  […]

Evolution Revealed?
April 22, 2008
When the news reports evidence for evolution in the fossils or genes, it sounds like Darwinism has been all but proved, because scientists have observed its effects.  Can these stories withstand deeper scrutiny? Lungless frog:  Science Daily reported a frog without lungs in Borneo.  Lunglessness in tetrapods has been reported in salamanders and other amphibians, […]

Moths Navigate in the Dark Against the Wind
April 12, 2008
A moth weighs little more than a piece of paper, but it does things no paper blowing in the wind can do: it can navigate with and against the wind to get where it needs to go.     Science Daily reported on work by UK scientists who used “entomological radar” to monitor where the […]

Evolution After the Fact
April 4, 2008
Many scientific theories are evaluated on their ability to make predictions.  Good theories suggest experiments that lead a researcher to discover new things.  In biology, however, “evolution” is a word often invoked as an after-market explanation for observations that emerged outside of the theory.  Here are some recent examples: Ant farm:  Science Daily reported on […]

Tuatara Genes Are Running in Place
March 24, 2008
One would expect a living fossil to show extreme stasis at the genetic level.  Not so for the tuatara, a New Zealand reptile, reported EurekAlert: researchers found that “although tuatara have remained largely physically unchanged over very long periods of evolution, they are evolving – at a DNA level – faster than any other animal […]

The Gecko in the Flight Simulator
March 17, 2008
It’s a lizard!  It’s a plane!  It’s Supergecko!  Researchers at UC Berkeley (where else) put a gecko into a wind tunnel to watch it fly.  News about gecko’s magic feet that allow it to run vertically up glass is almost old hat now (08/27/2002, 01/04/2005).  Even a gecko can lose its footing, though, and thereon […]

Animal Feats Inspire Imitation
March 14, 2008
Imagine carrying 850 times your own weight.  Step aside, Hercules, and meet the Hercules beetle: the strongest creature in the world.  Science Daily said that researchers in Belgium are not just impressed with its show of strength.  They are finding inspiration for “intelligent materials.”     The Hercules beetle has a shell that is able […]

A Step Closer to Gecko Adhesive
January 30, 2008
Scientists are getting closer to imitating the amazing wall-climbing ability of geckos.  Science Daily reports that a team from UC Berkeley manufactured tape with hard polymer fibers just 600 nanometers across that mimic the spatulae on gecko feet.     This latest attempt at imitating the gecko works only on smooth, clean surfaces, but requires […]

Butterfly Wings Flash Shiny Optical Tricks
January 22, 2008
You can get brilliant colors without pigment if you build patterns near the wavelengths of light.  Butterflies have the trick down to a science.  Their wings shimmer and shine with brilliant colors produced by nanostructures that scientists want to imitate.     Science Daily told how butterflies and moths, even the white-winged varieties, use nanostructures […]

Monarch Butterflies as a Test of Evolution
January 11, 2008
The Discovery Institute and the National Academy of Sciences have recently published books with butterflies prominently displayed on the cover.  The two books give opposite viewpoints on whether life was designed or a product of evolution.  Maybe a look at a real-world butterfly research project can shed light on the debate.     A paper […]

Yet Another Dinosaur Extinction Theory: Bugs
January 3, 2008
A press release from Oregon State claims that insects may have finished off the dinosaurs.  Two main reasons were given for this hypothesis: (1) the extinction coincides with the rise of flowering plants and their pollinators, and (2) the impact theory has serious problems. “There are serious problems with the sudden impact theories of dinosaur […]

Accurate Chemical Classifier Mimics Insect Nose
December 10, 2007
Two Germans have built a better chemical classification system by taking their inspiration from insect olfactory organs.  Here’s how they described their achievement in an abstract from PNAS:1 The chemical sense of insects has evolved to encode and classify odorants.  Thus, the neural circuits in their olfactory system are likely to implement an efficient method […]

Nature Inspires Useful Products
November 16, 2007
Some day soon you may be able to extract water out of thin air, decorate your walls with detachable wallpaper, read street signs clearly in fog, and employ reusable tape underwater.  These are some of the innovations coming from biomimetics – science inspired by nature’s designs. Venus flytrap:  Alex Crosby at University of Massachusetts was […]
