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 […]

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 […]

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 Workouts Work for Humans, Not Pickups
December 20, 2002
Space Daily began an article on space medicine with a thought-provoking comparison: Most machines don’t improve with use.  Old pickup trucks don’t gradually become Ferraris just by driving them fast, and a pocket calculator won’t change into a supercomputer by crunching lots of numbers.  The human body is different.  As weightlifters know, the more that […]

Human Genome Project: A “Worthwhile Failure”
November 20, 2002
The Human Genome Project (HGP) was filled with promise.  Walter Gilbert claimed in 1992 that it would bring about “a change in our philosophical understanding of ourselves… one will be able to pull a CD out of one’s pocket and say, ‘Here’s a human being; it’s me!’”  Why does philosopher-biologist Sahotra Sarkar consider that prospect […]
