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 […]

Who’s In Control: Your Brain or You?
March 12, 2010
Do you have a self that controls your brain, or is thought a secretion of the brain, as Darwin claimed?  Do you use your brain, or does your brain operate you?  Who is in charge?  These are deep philosophical questions with a long history, that some people prefer to avoid, as in the common joke: […]

Depressed? Believe in a Caring God
February 28, 2010
“Belief in a Caring God Improves Response to Medical Treatment for Depression, Study Finds.”  That’s what Science Daily said.  The statement assumes, of course, that psychiatry knows what depression is.  Another story on Science Daily worried that “Psychiatry’s Main Method to Prevent Mistaken Diagnoses of Depression Doesn’t Work.”     It makes sense that diagnosis […]

The Brain You Use, and How It Uses You
February 21, 2010
Neuroscientists continue to find out amazing things about the human brain.  In some ways we are responsible to use our brains, but in other ways the brain does things to us.  If nobody has figured out where the dividing line is for thousands of years, it’s unlikely we will today; but the following findings can […]

Who Should Be Listening to Scientists?
February 17, 2010

As a climate scientist and a contributing author to the Intergovernmental Panel on […]

Is Your Bod Flawed by God?
February 14, 2010
Are your body’s imperfections reasons for you to reject intelligent design and embrace evolution?  Professor John Avise (UC Irvine) thinks so.  His new book Inside the Human Genome was given good press by PhysOrg: “Distinguished Professor of ecology & evolutionary biology at UC Irvine, Avise also makes the case that overwhelming scientific evidence of genomic […]

Barefoot Is Better
January 27, 2010
Who do we wear shoes?  It seems obvious; we expect that they help us avoid injuries and provide comfort.  Maybe we should think of the injuries we are getting by wearing them.     The image of the barefoot person is usually of someone poor, deprived, lower-class, hick, unclean, redneck or something else unattractive.  Shoes […]

It Takes More than Eyes to See
January 6, 2010
We think of eyes as objects that see, but vision requires a whole system of parts.  One of the most important is the brain.  Without your thalamus, vision would be a hopeless jumble of jerky signals, reported scientists from the National Eye Institute.     Writing in PNAS,1 Ostendorf, Liebermann and Ploner found that the […]

In Brains, Size Is Not All that Matters
December 22, 2009
Two recent science articles indicate that scientists should be careful before inferring intelligence from brain size (picture).  PhysOrg reported on work to uncover the genetic basis of microcephaly – reduced brain size in humans.  “The cerebral cortex in particular has undergone a dramatic increase in surface area during the course of primate evolution,” the article […]

Debunker Busters
December 17, 2009
Often in science reports, new findings debunk previously held beliefs.  But then, a thoughtful reader might ask, didn’t the previously held belief debunk a belief prior to that?  Sometimes it gets difficult to believe the current belief has any credibility, when the debunkers turn on each other. A dilemma about dilemmas:  Psychologists and philosophers have […]

Science Flipflops
December 9, 2009
Science says… on second thought, science says the opposite.  Or, we’re not sure what science says.  The following recent stories show that things you thought science had proven may not be true at all.  What’s next? Take testosterone for fairness:  The image of the testosterone-crazed, egotistical, reckless, raging road warrior is all wrong.  At least, […]

What’s Natural for Humans?
December 1, 2009
Should humans do what comes naturally?  What comes naturally?  And what do we mean by natural?     Nicholas Wade in the New York Times said, “We May Be Born With an Urge to Help.”  He began with the same question: “What is the essence of human nature?”  Then he discussed evidence that infants have […]
