How Useful Is Evolution Theory?
May 7, 2008
Is evolution good for anything?  There’s no question it keeps a lot of scientists busy, but has it helped the proverbial man on the street?  Here are two perspectives.     Michael LePage hit the sales beat for evolution on New Scientist this week: Evolution is a beautiful theory.  It explains everything from why some […]

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.  […]

Inferences from Old Protein
April 26, 2008
The dinosaur leg bone with the soft tissue was back in the news.  Back in 2005 (03/24/2005), a femur from a T. rex broke open during transport and was found to contain pliable tissue and blood vessels with apparent red blood cells.  This was a “phenomenon, once thought impossible” for such tissues to have survived […]

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, […]

Itemized Deductions
April 15, 2008
Here are some free deductions to take the edge off Income Tax Day…. as long as one deduces correctly. Israel is picking a national bird.  So what feathered friend will represent the Holy Land?  “The nine finalists include the hoopoe, the owl, the spur-winged plover, and the griffin vulture, but no doves.”  Source: Science, Random […]

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 […]

Not Even Wrong: Darwin’s Tree Suffers Base Blow
April 11, 2008
Darwin’s “tree of life” icon is suffering another blow.  The root of multicellular life was supposed to be the simplest, most primitive animal.  Now, scientists are seriously considering that the mother of all animals was a complex animal with a gut, tissues, a nervous system and amazing light displays: a comb jelly.     PhysOrg […]

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 […]

Seeing Vision in a New Light
March 31, 2008
The eye is like a camera, right?  That picture is way too simplistic.  The eye-brain visual system does image processing and gleans information from photons in diverse and remarkable ways.  Here are some recent findings by scientists: Upward mobility:  A team of Harvard scientists found some retinal ganglion cells that sense upward motion.  Writing in […]

Squid Beak: “A Truly Fascinating Design”
March 30, 2008
A new class of flexible yet tough materials may be in our future, thanks to a study of squid beaks.  Scientists at University of Santa Barbara, reported National Geographic News and Science Daily, were curious how the squid anchors its tough, hard beak in soft tissue.  Try anchoring a knife in Jell-o and you get […]

Peacocks Don’t Dress for Success
March 26, 2008
The male peacock’s fancy feather show: an icon of Darwin’s theory of sexual selection, right?  Then why did Japanese scientists tell Discovery News that the females pay them little attention?     The article claims that the male’s appearance fails to interest, much less excite, the females, who seem to pay more attention to his […]

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 […]

Electronic Nose Can’t Outsniff Yours
March 19, 2008
Electronic nose makers are smelling your dust, said Science Daily.  “Despite 25 years of research, development of an ‘electronic nose’ even approaching the capabilities of the human sniffer remains a dream,” the article said.     Biological noses are great at discriminating between volatile compounds.  We can immediately sense things that are fruity, grassy, and […]

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 […]
