Haemoglobin More Complex than Thought: Regulates Blood Flow
July 16, 2004
Physiologists have long known that haemoglobin, the molecule that adds the redness to red blood cells and carries oxygen to the tissues, releases its oxygen as the blood vessels constrict.  Now, increasing evidence shows that haemoglobin (composed of four complex proteins that surround a central iron atom) is not just a passive oxygen carrier.  It […]

Can Natural Processes Create a Mind?
June 16, 2004
No problemo, says H. Clark Barrett (UCLA), getting a mind from mindless matter.  In a review of a book by developmental psychologist Gary Marcus published in Science June 11,1 Barrett was reassured by Marcus’ book that evolutionary theory working within natural law is up to the task: “The strengths of The Birth of the Mind […]

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 […]

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 […]

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 […]

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.”  […]

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.  […]

Seniors, Pay Attention: Stay Active

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 […]

Sex and Gender Cannot Be Separated
January 22, 2004
A study of male children born with a rare birth defect called cloacal exstrophy demonstrates that sexual identity is biologically determined, not a result of upbringing.  The report in Science Now shows that most of the boys identified themselves as male early on, even though unaware of their condition and “raised as girls” under doctor’s […]

Why You Need Sleep
January 21, 2004
A study in the Jan. 22 issue of Nature1 claims that sleep gives you inspiration.  Sleep is not just a waste of a third of your day; it helps consolidate memories, and provides pivotal insights.  “Insight denotes a mental restructuring that leads to a sudden gain of explicit knowledge allowing qualitatively changed behaviour,” the five […]
