Update on Interplant Internet
April 23, 2010
One of the early “amazing” stories reported in these pages concerned the startling observation that plants use a kind of “email” system in their own interplant “internet” (see 07/13/2001).  What has been learned in the nine years since that story appeared?  Quite a lot, and another fascinating article about plant communication appeared this week in […]

Maxwell’s Demon Helps Run Your Muscles
April 19, 2010
James Clerk Maxwell once speculated that the second law of thermodynamics could be violated if an agent or “demon” could sort the hot and cold molecules at a barrier, thus overcoming the tendency toward thermal equilibrium.  Something like this has been found at work in the molecular machines in our muscles.  The actin-myosin motor is […]

Genetic Subcode Discovered
April 18, 2010
Computer programmers know all about subroutines.  One master program can easily call other programs, which can return results back to the master program.  That’s very 1960s.  Today’s modular software responds dynamically from disparate sources and responds to feedback from embedded triggers.  They can call routines written in other codes or languages.  We’re beginning to find […]

Smelling Evolution in Bird Genes
April 7, 2010
The zebra finch genome has been sequenced; it revealed some surprises.  In the chicken, only 70 of the 500 genes encoding smell receptors produce active proteins.  In the zebra finch, 200 do.  What does this mean?  According to a press release from Weizmann Wonder Wander at the Weizmann Institute in Rehovot, Israel, it means Darwin […]

Human Genome “Infinitely More Complex” Than Expected
April 5, 2010
Ten years after the Human Genome Project was completed, now we know: biology is “orders of magnitude” more complicated than scientists expected.

“Synthetic Evolution” – Is it Really Intelligent Design?
March 18, 2010
Some Cambridge scientists engineered a four-character genetic code and made some proteins with it.  They guided the process at every step, but claim that they “evolved” this code.  Is that a fair use of language?  This strange admixture of concepts is found in today’s issue of Nature.1  The confusion began right in the title: “Encoding […]

Search for Intraterrestrial Life Scores Big
March 16, 2010
Single-celled organisms may be tiny, but what they lack in bulk they make up for in volume and importance.  Scientists have been appreciating more than ever the ubiquitous presence of microbes on our planet and the roles they play to sustain the biosphere.     PhysOrg reported that half of the world’s life may lie […]

Robotic Pothole Crew Keeps Your Genetic Highways in Good Repair
March 14, 2010
What a thought – a repair crew of molecular machines roaming the strands of your DNA, fixing errors 24 x 7.  It happens.  New techniques are showing the machines jumping from strand to strand like fleas, stopping at suspicious points, and fixing errors, reported Science Daily.  Dr. Bennett Van Houten (U of Pittsburgh Cancer Institute) […]

Fruit Flies: From Darwin to Design
March 13, 2010
The fruit fly Drosophila melanogaster is an icon of evolution.  Since the 1930s these poor little bugs have been mutated endlessly and watched for signs of Darwinian change.  So far, though, only useless mutants, unable to survive in the wild, have been produced.  Recently, scientists seem more enamored with their design.  Two recent articles had […]

What Good Is Natural Selection without Progress?
March 8, 2010
Three papers recently claim to have seen natural selection.  None of them, however, identified a functional advantage that would have tied changes to novel benefits that could improve a species.  Yeast:  “New Type of Genetic Variation Could Strengthen Natural Selection,” trumpeted a headline in Science Daily.  It was about a study of two varieties of […]

Life Crams Stuff on the Long Road
March 7, 2010
This quote from UC Berkeley wins Stupid Evolution Quote of the Week: In the long evolutionary road from bacteria to humans, a major milestone occurred some 1.5 billion years ago when microbes started building closets for all their stuff, storing DNA inside a nucleus, for example, or cramming all the energy machinery inside mitochondria. Any […]

Life Leads the Way to Invention
February 26, 2010
Here’s a factoid for the party: a cell is 10,000 times more energy-efficient than a transistor.  PhysOrg tells us that “ In one second, a cell performs about 10 million energy-consuming chemical reactions, which altogether require about one picowatt (one millionth millionth of a watt) of power.”  This and other amazing facts lead to an […]

Hopeful Monsters and Other Tales: Evolutionists Challenge Darwin
February 24, 2010
Two recent articles show that Darwin is not invincible.  On one side he is being attacked by hopeful monsters.  On the other, he is being attacked by an atheist truth-seeker.  Neither of these attacks are coming from creationists. Return of the hopeful monster:  Tanguy Chouard raised eyebrows in Nature News with a headline that sounds […]

Evolutionary Inferences: Are They Incontrovertible?
February 23, 2010
No matter what is found in plants or animals, it finds its way into an evolutionary explanation eventually.  Are these explanations driven by the data, or forced into a belief system?  Are other explanations possible?  Some recent reports might inform these questions.

Molecular Highway Motor Comes into Focus
February 19, 2010
A beautiful new image of kinesin, a molecular machine that carries cargo on cellular highways, has been produced in greater detail than ever by a team at Berkeley and Brandeis Universities.  Science Daily published a picture and description of how kinesin works.  “Life’s smallest motor – a protein that shuttles cargo within cells and helps […]
