Plant Pores March to Their Own Beat
December 22, 2006
Plants have pores called stomata that open and close (see 09/13/2006).  These gates of the leaf surface provide plant protection from invaders, and allow the transpiration of gases and water vapor in and out, depending on conditions.  The stomata of many plants open wide during the day to allow in carbon dioxide, but close at […]

Stupid Evolution Quote of the Week:  Comets as Life’s Lego Jumper Cables
December 15, 2006
Results of the Stardust mission made the cover of Science this week.1  The Jet Propulsion Laboratory put out a press release that condensed the abstruse papers into a simplistic story built around the L word life.  Publicist David Agle wrote for the Lego generation: Just as kits of little plastic bricks can be used to […]

Darwinists Award New Inductee
December 11, 2006
The journal Science published the winning entry in the 2006 contest “GE and Science Prize for Young Life Scientists.”  The Grand Prize went to Irene A. Chen (Harvard) for her essay entitled, “The Emergence of Cells During the Origin of Life.”1  Her chemical-evolution scenario makes generous use of that word emergence and its synonyms. Modern […]

To Get Complex Life, Just Add Oxygen
December 10, 2006
A story is circulating in the science news media that a burst of complex organisms in the Cambrian coincided with a rise in oxygen in the atmosphere.  Reporters seem to be drawing a cause-and-effect relationship.  Examples: News@Nature:  “A sharp increase in the amount of oxygen in the air may have sparked the evolution of complex […]

How Your Joints Auto-Lubricate Themselves
December 7, 2006
Motion sets up an automated process that produces more lubricant for the joints, scientists at UC San Diego found.  EurekAlert explains how shear forces on cartilage stimulated it to produce proteoglycan 4, which secretes joint fluid where it coats and lubricates cartilage surfaces.  This way, the fluid is produced according to the need of the […]

Darwin Stars at the Galaxy, by Universal Pictures
December 7, 2006
A press release from the European Southern Observatory asks, “Do Galaxies Follow Darwinian Evolution?”  One may wonder how stars, which do not bear children, can be considered progeny of Charles Darwin.  They explain: The ‘nature versus nurture’ debate is a hot topic in human psychology.  But astronomers too face similar conundrums, in particular when trying […]

The Physics of Gecko Toes
December 6, 2006
Why would anyone want to know the details of physical forces when gecko feet walk on glass?  Here’s why: “The results have obvious implications for the fabrication of dry adhesives and robotic systems inspired by the gecko’s locomotion mechanism.”  A team of scientists from Santa Barbara and China watched gecko toes peel off glass and […]

Darwin Missed the Beetle Can Opener Trick
December 5, 2006
You know those big horns on rhinoceros beetles?  They’re not just for showing off.  Scientists at Indiana University found a “surprising function” for them.  It turns out “horned beetles use their young horns as a sort of can opener, helping them bust out of thick larval shells.”  The function of horned beetles’ wild protrusions has […]

Stupid Evolution Quote of the Week:  Evolution as Inventor
December 5, 2006
This week’s award goes to Gines Morata, a research professor in Spain, who was interviewed in Current Biology.1  He gives us a glimpse into his biology classes: I often tell my students that they do not have to invent anything; in biology everything has already been invented.  What they have to do is find out […]

How Does the Emperor Penguin Dive So Deep?
December 1, 2006
Using a small recorder mounted on an emperor penguin, researchers at Scripps Institute measured the bird diving as deep as 1,800 feet – six times the depth any human has survived unassisted.  This is much deeper than scientists had expected.  Live Science surmises that if we could figure out how they do it without getting […]
