How Many Neurons Does It Take to See a Picture?
June 8, 2004
Israeli scientists publishing in Current Biology1 attempted to determine how many neurons participate in the representation of a single image.  At least a million was their conservative answer: probably more like 30 or 300 million or more.  They made careful measurements of neural activity when subjects were shown a face or a house.  In the […]

Neural Darwinism: The Evolution of Truth
June 3, 2004
Can evolutionary theory build a bottom-up explanation of higher cognitive functions?  David Papineau (King’s College) doubts it.  In his review of The Physiology of Truth: Neuroscience and Human Knowledge by Jean-Pierre Changeux (transl. Malcolm DeBevoise, Belknap Press: 2004), published in the June 3 issue of Nature,1 he gives the author high marks, but concedes that […]

Exercise Your Nerves
May 27, 2004
A team of neurologists from UCLA and duPont Hospital for Children in Delaware found that voluntary exercise improves regeneration of neurons, both for those who work out, and for those recuperating after injury.  The abstract in PNAS1 states: Recent advances in understanding the role of neurotrophins on activity-dependent plasticity have provided insight into how behavior […]

Stem Cell Cover-Up?
May 24, 2004
Stem cells, most have heard, hold promise for many life-saving cures.  Michael Fumento in Insight Magazine claims that while adult stem cells have shown many positive results, the media and science establishments tend to hype the benefits of embryonic stem cells while glossing over the ethical and moral problems they present.     Recently, Nature1 […]

Male Imparts More to Embryo than Just DNA
May 12, 2004
A team of biologists have confirmed that male sperm RNAs are delivered to the oocyte along with the DNA.  Specifically, paternal messenger RNAs are delivered to the egg.  These might influence development and put the male’s imprint on the developing zygote.  Writing in Nature,1 the researchers speculate what the finding means: Why should spermatozoa messenger […]

Is It Possible to Be Too Clean?
April 16, 2004
Mr. Clean may have a bad immune system.  A story in EurekAlert says kids without enough exposure to infectious agents are at greater risk of autoimmune diseases.  “The cleaner everyone is, the less stimulation their immune system gets,” says [Nora] Sarvetnick [of Scripps Research Institute]. “Their immune system tends to be incomplete.”  Stimulation increases the […]

Sober Up About Alleged Alcohol Benefits
April 7, 2004
The Brits are not about to take an axe to the pubs, but Nature this week published two sober warnings about the dangers of alcohol abuse.  They warn that the oft-claimed benefits of drinking in moderation apply only to a few groups (primarily the elderly), and are drowned in the known health risks.  “We pay […]

In Defense of Men and Women, Body and Soul
March 31, 2004
The BBC News published a male-bashing article by Baroness Susan Greenfield, Director of The Royal Institution, on March 29.  It must have created a stir, because the next day, Prof. Steve Jones of University College, London, tried to restore the male ego.  This was apparently a two-part documentary exploring what would happen “If women ruled […]

How to Prevent Youthful Violence
March 4, 2004
EurekAlert posted a finding by University of Washington sociologists that “Family discipline, religious attendance, attachment to school cut levels of later violence among aggressive children.” Do we really need scientists to tell us the obvious?  Everyone seems to know this except secular researchers.  Solomon and Paul can tell the University of Washington all they need […]

We Don’t Know How We Know that Genes Make Minds
February 29, 2004
“If the mind can be explained from the workings of the brain, and the brain develops by direction from our genes,” Anthony Monaco (Oxford) writes, “then presumably the mind can be explained from our genetic make-up.  But how can only 30,000 genes make a brain with billions of neurons and encode the particular aspects of […]

No Man Is an Island – We Are the World
February 28, 2004
Myriads of organisms live in and on our bodies, reminds an article in the Feb. 27 issue of Science,1 and they’re not just freeloaders on a hayride.  We need them, and they need us.  “We are not alone,” claim the three microbiologist authors, but “we get by with a little help from our (little) friends.”  […]

Cardiovascular activity is good for everyone.  Seniors can benefit from taking walks, too.  A new study shows it can help the elderly keep their attentiveness and improve mental performance.  Science News1 reporter Bruce Bower writes: Seniors interested in pumping up their brains and maintaining an attentive edge might consider taking this inexpensive prescription: Go for […]

Evolution of Language Debated
February 27, 2004
The Feb. 27 issue of Science features the topic of the evolution of language.1  The thousands of words in 10 articles might be summarized by the title of a book review by Andrew Carstairs-McCarthy: “Many Perspectives, No Consensus.”2 Since there are many perspectives and no consensus, language evolution is one of the subjects Darwinists love.  […]

Why Darwin Is Like Yoda, and Darwinism Like Marxism
February 4, 2004
Homage for the master is palpable in John Vandermeer’s review (Science, Jan. 23)1 of a thick new book entitled Niche Construction: The Neglected Process in Evolution by Odling-Smee, Laland and Feldman (Princeton, 2004).  Vandermeer seems almost worshipful in his opening lines: The nascent germ of many novel ideas in biology can be traced directly or […]
