Discovering Health and Technology in the Human Body
June 7, 2009
Why invent technology from scratch, when the body contains substances that point the way to high tech, and can heal almost like magic?  Several articles show that harnessing the body’s own resources is the wave of the future.     Umbilical cords were usually tossed into the maternity ward biowaste can, but now they are […]

Who Needs Embryonic Stem Cells?
May 3, 2009
Cells can be “reprogrammed” to act just like embryonic stem cells, a Nature stem cell blog called The Niche reported.  This eliminates the need to use viruses or inserted DNA to induce the cells to become pluripotent.  The resulting cells are “morphologically indistinguishable” from embryonic stem cells, the article said.     The prior week, […]

Is Darwinism Useful Explaining Cognition?
April 15, 2009
One would think the evolution of mind involves a straightforward account of improving cognition as one progresses up the evolutionary tree.  It’s not so simple, said two researchers in a Nature essay:1  Darwin’s theory of evolution by natural selection is broadly accepted among biologists, but its implications for the study of cognition are far from […]

Stem Cells Polarize Ethics
April 7, 2009
Adult stem cells are continuing to promise revolutionary therapies, while embryonic stem cells remain a political football even after Obama’s loosening of restrictions.  Some stories seem to suppress the word “embryonic” and just talk about “stem cells,” but there is a big difference in the ethics of one over the other.  Embryonic stem cells require […]

Your Eye Works a Precision Jigsaw Puzzle
April 7, 2009
You have twin 125 megapixel video cameras in your eyeballs.  Each pixel, a rod or cone connected to a neuron, sees only a small bit of the total image.  How do these bits, like pieces of a jigsaw puzzle, fit together?  Scientists at the Salk Institute have found that they are finely tuned to fit […]

Can Evolution Be Programmed?
April 6, 2009
Some researchers are employing “evolutionary computing” as an algorithm to solve problems.  But is it really evolution? Evolved machines:  A company called Evolved Machines in Palo Alto announced a 40-teraflop machine that will be used for the “artificial evolution of neural circuitry” (see press release on United Business Media).  “It is self-evident that in biological […]

Ye Are the Salt of the Evolution
March 11, 2009
Salt is good, the good book says (Mark 9:50).  Another good thing it may do for you, according to Science Daily, is act as “Nature’s Antidepressant.”  Presumably it’s hard to have a good mood about a steak with no salt on it.  In the midst of this article about the mood-enhancing effects of salt, an […]

Gobekli Tepe: What Mean These Ancient Stones?
March 10, 2009
Imagine stone carvings and monuments whose age make the pyramids and Stonehenge look like artifacts of modern history. Such monuments exist on a hill in Turkey at a site called Gobekli Tepe. Squared-off limestone blocks stacked like the letter T, arranged in circles, with ornate animal carvings on them, have been baffling archaeologists for the […]

Elect Obama, Get Embryonic Stem Cells
March 8, 2009
President Obama is about to fulfill of his campaign promises: lifting restrictions on creating new embryonic stem cell lines (see Fox News).  The question now is, are they really needed?  They have yet to show any successes, while adult stem cells are enjoying an accelerating boom of amazing discoveries that could provide hope for some […]

Adult Stem Cells, +2; Embryonic Stem Cells, -1
February 23, 2009
Two more successes were chalked up for adult stem cell therapies recently.  Science Daily said that sufferers from Crohn’s disease may have a new treatment option by getting injections of their own bone marrow stem cells.  This “now constitutes a treatment option to cure an intestinal disease that sometimes does not successfully respond to drugs […]

Assassins Roam Our Highways
February 22, 2009
Slinking surreptitiously through our blood streams, the assassins prowl about, looking for their targets.  These are not terrorists or vigilantes.  They have a license to kill.  Be glad they are there; they have saved your life many times.  They are called natural killer cells.     PhysOrg reported on work going on at Howard Hughes […]

Language Is Not a Simple Genetic Matter
February 18, 2009
It sounds so simple.  The title on an article in PhysOrg announced, in Kipling Just-So Story Format, “How gorilla gestures point to evolution of human language.”  Because gorillas have an extensive repertoire of over 100 gestures, human conversation was only a matter of evolutionary time.  Is this mere storytelling, or do such explanations have scientific […]

Obama and Stem Cells: Hope Chest or Pandora’s Box?
January 31, 2009
Any day now, as he promised, President Obama will likely lift funding restrictions on embryonic stem cell research imposed by former President Bush.  Bush had sought the council of leading scientists and ethicists before making his decision.  Obama, by contrast, will be yielding to the opinions of the scientific societies who have clamored for years […]

Immune System Has a Code, Language and Memory
January 24, 2009
“Decoding the language of memory cells” is the title of an article in Science Daily.  A researcher at the University of the School of Medicine is using the concepts of codes, language and memory to understand the way T-cells “remember” a pathogen to prevent later infections.  “We are currently figuring out which signals are important […]

Exploring the Malleability of Evolutionary Explanation
January 23, 2009
Is evolutionary theory just a very malleable and ductile idea, able to adapt to changing observations, or should it be described as a strong theory, powerful in its explanatory breadth?
