To Advance Technology, Make Like Nature
January 12, 2010
Scientists and engineers continue to find the most elegant solutions to practical problems by looking at plants and animals.  Here are a few of the recent examples. Wet computing:  Cells and brains do a superior job of complex processing, so why are our current computers singing how dry I am?  Not for much longer.  Science […]

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 […]

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 […]

Seeing Sound and Hearing Light
November 28, 2009
Synesthesia, the syndrome in which people’s senses become confused, may not be so off the wall.  Research at the University of British Columbia “flips the traditional view of how we perceive the world on its head.” Experiments show that our brains perceive the world by synthesizing multiple inputs.  The latest evidence of this is that […]

In Brains, It’s Quality, Not Quantity, that Counts
November 17, 2009
Most anthropologists are obsessed with brain size.  How many cc’s (cubic centimeters) of brain could fit in the skull of this or that hominid?  PhysOrg reminds us that “Bigger not necessarily better, when it comes to brains.”  Here’s a shocker from scientists at Queen Mary University: “Tiny insects could be as intelligent as much bigger […]

What Is Man?
November 5, 2009
Science often makes pronouncements about the human species.  We should be mindful of the worldview behind them.     Live Science published an article with the confident-sounding title, “Human Evolution: Where We Came From,” accompanied by the iconic sketch of Ardi (see 10/02/2009) and an obligatory reference to Darwin.  Even though reporter Charles Q. Choi, […]

Human Evolution Celebration Exposed
September 24, 2009
The evolutionary story of human origins is often told like a cultural myth that is intuitively obvious.  Humans emerged in Africa after their ancestors came down from the trees and walked upright.  They began to hunt with stone tools and used fire.  They migrated north out of Africa and populated Europe, overtaking the Neanderthals who […]

Your Eye Sees Trouble Before You Do
September 10, 2009
In slapstick comedy, the fall guy gets the pie in the face when the clown in front of him ducks.  It’s funny because most of us instinctively duck when we see something coming.  But two recent experimental studies are revealing new automated capabilities built into the eye and brain that are quicker and more automatic […]

Mutation: Not a Bug, a Feature
September 2, 2009
Evolutionary biologists are sometimes risque with the way they discuss mutations.  They treat them almost like magic wands, able to produce wondrous new organs and functions by accident. Health to them, death to you:  One article on Science Daily discussed a mutation that causes congenital heart disease in humans, but may have been a stepping […]

Your Throat Has Tasteful Antennae
August 30, 2009
Our airways are lined with cells that have beating oars called motile cilia.  Like galley slaves on a Roman ship, they beat in coordinated waves, setting up currents that propel dust and foreign matter out toward the mouth.  Scientists just found out another amazing capability of these motile cilia: they can “taste” toxic chemicals and […]

Appendix to The Origin: “Darwin Was Wrong”
August 21, 2009
The appendix, that lowly dollop of tissue relegated to vestigial organ status by the Darwinians, is alive and well with new respect.  Science Daily announced results of the “first-ever study of the appendix through the ages.”  Conclusion: “Charles Darwin was wrong: The appendix is a whole lot more than an evolutionary remnant.  Not only does […]

Don’t Just Sit There; Do Something
August 10, 2009
Inactive people have the most health problems.  That’s why the American Psychological Association is warning that sedentary lives can be deadly, according to Science Daily.  A speaker at an APA convention called physical inactivity “the biggest public health problem of the 21st century.”     Some 25-35% of adult Americans – 40 to 50 million […]

Spleen Scores, Darwin Loses
August 4, 2009
Hold onto your spleen if you can.  The lowly organ, “known as much for its metaphoric as its physiological value, plays a more important role in the body’s defense system than anyone suspected.”  Natalie Angier reported in the New York Times that Harvard researchers found that the spleen acts like a fort for disease-fighting monocytes, […]
