It’s not all in the genes. Ask any epigeneticist. Ramifications for cloning.

Check out these identical twins:

They are really identical twins.  This photo is from the November 2006 issue of Discover Magazine.  See the related article: “DNA Is Not Destiny The new science of epigenetics rewrites the rules of disease, heredity, and identity.”

Though these two men are genetically identical, they were separated at birth.  The man on the left was malnourished for years.   Bone structure changes brought about by environmental factors is thus one of many ways (physical and behavioral) in which the environment can dramatically affect the way in which the genes express themselves

As the Discover article points out, the 25,000 genes of our human DNA are widely considered to be an instruction book for our bodies.  However, “genes themselves need instructions for what to do, and where and when to do it.”  These additional instructions are not in DNA, but

on it, in an array of chemical markers and switches, known collectively as the epigenome, that lie along the length of the double helix.  These epigenetic switches and markers in turn help switch on or off the expression of particular genes.

It has long been known that epigenetic switches are critical to the healthy development of organisms.  These can be dramatically tweaked by exposure to a vitamin, a toxin or even mothering, altering “the software of our genes in ways that affect an individual’s body and brain for life.”  Green tea, for example, has been shown to prevent the growth of cancers. 

New research has even …

Bloggers Need FireFox 2 for Live Spell Checking in Forms

OMG! I just installed the FireFox 2 browser and noticed something. It spell checks form entries as you type! Just as Word and its ilk do in their documents. Since its inception, I'd been using FireFox just because of speed, safety and security advantages. I added the Google toolbar only…

Language wars: it all begins with subtle early skirmishes

Recently on Huffpo,George Lakoff has written an important piece on the ongoing political battle to define words.

I’m keenly aware of this battle.  Here’s one way it affects me.  I do not believe in a sentient Creator.  Some would label me an atheist, but that would be horrible unfair.  Why?  Because that term has been successfully loaded with far more than lack of a belief in a traditional God.  The conservative movement has successfully defined “atheists” as strident, immoral, untrustworthy and threatening to America’s families. 

This ugly baggage is why I have embraced the term Bright. I am a “bright.”  I have a naturalistic worldview free of supernatural and mystical elements.  Does that make me threatening?  I don’t think so.  Does it make me prone to mob violence like members of many religious groups?  I would think the opposite—I have to cut my own philosophic path thorough life.  I doubtless have different politics and beliefs than many other Brights.  Narrowly construed, I’m an organization of one.  But there are certain people are perturbed with me, I’m sure, because I refuse to claim allegiance to the insecure God of the Bible and we just can’t have that.

The word battles, however, are taking place on many other fronts.

As Lakoff writes, such word battles comprise “the struggle to define our democratic principles and values. The right wing has worked for decades to alter the meanings of concepts that define our way of life.”  For instance, consider the word “liberal.” …

See no evil: comments on the comments to the Bart Ehrman post

My earlier post regarding Bart Ehrman was not meant to provoke in an outrageous way, although I suspected that it might distress some people.  That post drew much more traffic than we are used to at the site, approximately 25,000 unique visitors in three days.  It also pulled in more than 200 comments.  I was intrigued by the nature of the comments, especially those comments written by people who ostensibly disapproved of Ehrman’s work or his conclusions.  In fact, I did a small informal analysis based upon the comments posted by last night (I believe there were about 150 comments posted at that time).

I need to state at the outset that there were more than a few Believers among the commenters who appreciated and even applauded Ehrman’s work.  Some of these Believers specifically stated that even if Ehrman was correct, they could still believe in God and Jesus, they could still be good Christians and they found that Ehrman’s work had enriched their understanding of the Bible. My criticism of the distressed commenters is not directed toward these people.

Approximately 35 of the comments were written by people who appeared to be distressed or dismayed by Ehrman’s work.  Notably, only three of those commenters acknowledged the basic points made by Ehrman. 

What were Ehrman’s basic points?  That earlier manuscripts did not contain some information that was contained in some of the later manuscripts that were ultimately adopted part of “the Bible.” Therefore, the new material found in later writings …

Actors, athletes, tell us not to try to save lives using stem cell research

Here is a video of the latest bit of fundie propoganda, airing in Missouri, where voters will soon have the opportunity to vote "yes" to allow the full range of stem cell research.  These anti-stem-cell actors and athletes should be made to walk through hospitals and hospices.  They should be made to…
