Beth and I have been married a month today. It hardly feels like it though. Maybe it's the multiple weddings we've attended, maybe it's the weeklong honeymoon where we were away from Georgia, but it doesn't feel like it's been that long.
The days have just flown by.
Right now other than working we're spending time cleaning the house, putting things where they belong, getting the necessary services (internet, hopefully within this week; trash service, etc.), and so on. We haven't heard from a lot of people, or gotten in contact with many, but we would like to get back into the swing of hanging out, and hopefully having a get-together pretty soon!
And if you're like me and really bad at budgeting, check out this AMAZING (but unfortunately not free) online budgeting site: www.mvelopes.com. It's pretty incredible.

Clinton Vs. Obama
After the past couple weeks or so, it's obvious Clinton is just doing laps around Obama.
Obama, the poor guy, just doesn't know what he's doing. And I don't know if it's a ploy by Hillary to Just look more mature than the Illinois Senator, but it apparently isn't hard at all.
In the CNN Youtube debate, when the Democratic candidates were asked if they would get together with dictators (Kim Jong, Fidel, etc.) within the first year, Obama said of course. He also said it was a "disgrace" that it wasn't happening now. (I think it's rather amusing that he'd be so eager to speak with these people while backing out of a Fox News debate) Clinton came back to say she wouldn't be so quick to meet, she said it would be completely based on the context of the situation and whether her meeting might be used as propaganda for the countries involved.
Similarly, when asked about using nuclear weapons, Obama said that he would never use them, and then amended the statement, saying he would never use them when civilians were involved. Hillary Clinton chastized Obama, saying that past presidents and powers have used nuclear threats to maintain peace, and it would be unwise to just come out and say that you would never use them.
Now, as I said, I'm not sure if these responses are just to make Hillary look more mature than the Obama the lightweight, but it's working.

Guess What??
Guess who's going to be drumming with Bright Eyes on a six week tour beginning in September?
That's right. My step-brother Clay Leverett.

An Update
Hey all,
Well, it's been a while (..... and it'll be a while.....)
Just want to let you know that all is well, this week I began a trial period at a potential full-time job in Atlanta. I'm an Audio Editor for Leading the Way with Dr. Michael Youssef (www.leadingtheway.org--I would link it but I"m on a mac for now). I'm not well acquainted with the ministry, but I've heard he's pretty solid. It's a job.
Things have been pretty great. Yesterday, Beth and I received gifts from a very kind relative of hers, and I couldn't believe my eyes:
So that's been pretty stinkin' exciting.... although I haven't had much of a chance with it.
Also, be sure to watch out for the Honeybadgers!!

Back Attack
Well, guys, I'm back.
Since I last wrote I think my life has changed in almost every way possible. Except I'm still a man. And still left-handed. And other things.
There's a lot to write about, and it'll all have to wait for the moment. But I hope to be back in touch soon. :-D

Reprogrammed fibroblasts identical to embryonic stem cells
Now this is cool.
Problem solved:

Reprogrammed fibroblasts identical to embryonic stem cells
CAMBRIDGE, Mass. (June 6, 2007) — Embryonic stem cells are unique because they can develop into virtually any kind of tissue type, an attribute called pluripotency. Somatic cell nuclear transfer ("therapeutic cloning") offers the hope of one day creating customized embryonic stem cells with a patient's own DNA. Here, an individual's DNA would be placed into an egg, resulting in a blastocyst that houses a supply of stem cells. But to access these cells, researchers must destroy a viable embryo.
Now, scientists at Whitehead Institute have demonstrated that embryonic stem cells can be created without eggs. By genetically manipulating mature skin cells taken from a mouse, the scientists have transformed these cells back into a pluripotent state, one that appears identical to an embryonic stem cell in every way. No eggs were used, and no embryos destroyed.
“These reprogrammed cells, by all criteria that we can apply, are indistinguishable from embryonic stem cells,” says Whitehead Member and MIT professor of biology Rudolf Jaenisch, senior author of the paper that appeared online June 6 in Nature.
“We are optimistic that this can one day work in human cells,” says Marius Wernig. “We just need to find new strategies to reach that goal.”
What's more, these reprogrammed skin cells can give rise to live mice, contributing to every kind of tissue type, and can even be transmitted via germ cells (sperm or eggs) to succeeding generations. "Germline transmission is the final and definitive proof that these cells can do anything a traditionally derived embryonic stem cell can do," adds Jaenisch.
Two additional papers report similar findings. The first, by Shinya Yamanaka of Kyoto University, will be published in the same issue of Nature. The second, from Konrad Hochedlinger, formerly of the Jaenisch lab and now at the Center for Regenerative Medicine at Massachusetts General Hospital and Harvard Stem Cell Institute, will appear in the inaugural issue of the journal Cell Stem Cells. Additionally, another paper in Nature from Kevin Eggan, also of the Harvard Stem Cell Institute and a former member of the Jaenisch lab, describes using mouse zygotes, rather than eggs, for somatic cell nuclear transfer.
Jaenisch cautions that "all these results are preliminary and proof of principle. It will be awhile before we know what can and can't be done in humans. Human embryonic stem cells remain the gold standard for pluripotent cells, and it is a necessity to continue studying embryonic stem cells through traditional means."
In August 2006, a team of researchers at Kyoto University led by Yamanaka reported a landmark discovery that by activating four genes in a mouse skin cell, they could reprogram that cell into a pluripotent state resembling an embryonic stem cell. However, the resulting cells were limited when compared with real embryonic stem cells, and the Kyoto team was unable to generate live mice from these cells.
A team of researchers decided to replicate this experiment, while refining certain technical aspects. This group was led by Jaenisch lab postdoctoral researchers Marius Wernig, Alexander Meissner and Tobias Brambrink; graduate student Ruth Foreman; and Manching Ku, a research fellow from Bradley Bernstein's lab at Massachusetts General Hospital. Konrad Hochedlinger also contributed.
Using artificial viruses called vectors, the team activated the same four genes in a batch of mouse skin cells. These genes, Oct4, Sox2, c-Myc and Klf4, are called transcription factors, meaning that they regulate large networks of other genes. While Oct4 and Sox2 are normally active in the early stages of embryogenesis, they typically shut down once an embryo has developed beyond the blastocyst stage.
"We were working with tens of thousands of cells, and we needed to devise a precise method for picking out those rare cells in which the reprogramming actually worked," says Wernig. "On average, it only works in about one out of 1,000 cells."
To test for reprogramming, the team decided to zero in on Oct4 and another transcription factor called Nanog. These two hallmarks for embryonic stem cell identity are only active in fully pluripotent cells. The trick would be to figure out a way to harvest Oct4- and Nanog-active cells from the rest of the population.
The answer came in the form of a laboratory technique called "homologous recombination." Here, the scientists took genetic material known to be resistant to the toxic drug neomycin, and spliced it into the genomes of each cell right beside Oct4 and Nanog. If Oct4 and Nanog switched on, the drug-resistant DNA would also spring into action. The researchers then added neomycin to the cells. Only those fully reprogrammed cells with an active Oct4 and Nanog survived.
Next, the team ran these cells through a battery of tests, seeing if they could discover any substantial differences between these cells and normal embryonic stem cells.
"In all tests, both genetic and epigenetic, there were no molecular markers distinguishing these two groups," says Meissner.
But definitive proof would only come through demonstrating that these cells could actually develop into any kind of body tissue and cell type. The researchers approached this question in three ways.
First, they fluorescently labeled these reprogrammed cells and injected them into early-stage embryos, which eventually gave rise to live mice. While these mice consisted of both the reprogrammed cells and the natural cells from the original embryo, the fluorescent tags indicated that the reprogrammed cells contributed to all tissue types in the mouse—everything from blood to internal organs to hair color.
Next, they bred these mice and found lineages of the reprogrammed cells in the subsequent generation, proving that these new cells had contributed to the germ line.
Finally, the team took advantage of another lab technique that involves creating a genetically abnormal embryo whose cells all consist of four chromosomes, rather than two. Because of this aberrant formation, the embryo can only form a placenta, and cannot develop into a full-term fetus. The researchers injected the reprogrammed cells into this embryo, and then implanted it in a uterus. Eventually live late-gestation fetuses could be recovered—created exclusively from the reprogrammed cells.
"This is the most stringent criteria anyone can use to determine if a cell is pluripotent," says Jaenisch.
Still, many technical hurdles remain for possibly translating this work to human cells. For example, the homologous recombination technique used to isolate the pluripotent cells does not yet work in human embryonic stem cells. Also, using cells that contain viral vectors can pose health risks.
"We are optimistic that this can one day work in human cells," says Wernig. "We just need to find new strategies to reach that goal. For now, it would simply be premature and irresponsible to claim that we no longer need eggs for embryonic stem cell research."

Getting a Marriage License
So yesterday Beth and I had one and only one objective--get a marraige license.
We leave early to get it over with, and carry with us a letter from our pre-marital counselor. Unfortunately, when we got there we found out that the letter was missing some requirements to grant us the special discount. While a marriage license is normally $51, if you have at least six hours of counseling it is dropped to $16. Not a bad deal.
So we decide to save our money and get the letter that we need. We call Beth's church, thinking that we can get them to verify the information and then print a letter on a letterhead with a signature (the two items needed to legitimize it). We do all that, and we're finally back to try again. This time, it doesn't work either. They can't accept it, and we just give up and pay the $51 fee.
What was going to be a relatively simple task turned into a day of craziness.
