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 […]

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 […]

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 You Need Heavenly Sunshine for Vitamin D
December 12, 2003
Rickets is on the rise again, along with other diseases caused by vitamin D deficiency, reports Erik Stokstad in the Dec. 12 issue of Science1.  Most vitamins we take in the mouth.  Why do we need to stand outside for this one?  He explains: Vitamin D is a steroid hormone that helps regulate calcium, an […]

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 […]

No More Excuses: You Have Time to Work Out
September 20, 2002
If you use the excuse that you don’t have the time to exercise, consider a study from McMaster University in Canada that found a short, 20-minute intense workout can be just as effective as two hours of moderate exercise.  You can manage 20 minutes, can’t you?  Another Canadian study mentioned on EurekAlert claims that walking, […]

Adult Stem Cells Lead Health Progress
July 20, 2002
51; Adult stem cells (AS) and induced pluripotent stem cells from adult tissues (iPS) continue to rack up tallies over embryonic stem cells (ESA).  Do we really need the embryonic variety?  Some continue to say yes, even though the practice of harvesting human embryos creates serious ethical questions for many. Controlling fate:  If you’d rather […]

Sunshine Is for Health
