Historical Accuracy of the Old Testament

Archeology keeps giving us reasons to believe that the history of Israel we find in the Old Testament is an actual account of real events rather than some epic storytelling of the period. Eric Metaxas, who shares the "Breakpoint Commentaries" duties since the death of Chuck Colson, explains.

The findings at Sorek [of an 11th century BC coin of a man with long hair fighting a large animal, suggesting that Samson-like men actually exited before the account in the Bible] are only the latest in a series of archaeological discoveries that are changing the way modern historians look at biblical narratives. It’s becoming more difficult for them to maintain that the narratives are pious fictions invented long after the era being depicted.

The most famous of these discoveries is the 1994 discovery of a stele in Tel Dan bearing an inscription that contained the words “House of David.” It was the first extra-biblical evidence of the Davidic dynasty. Prior to the discovery, many scholars doubted that David ever existed, much less founded a dynasty. The discovery was so out-of-line with expectations that more than a few insisted it must be a forgery.

Today, it is clear to even the most skeptical scholar that—surprise!—there really was a David who founded a ruling dynasty. That dynasty included his son, Solomon, and evidence of Solomon’s building projects described in Second Samuel have been found by archaeologists as well.

The Bible tells us about God because the events that it represents as historical are, indeed, historical. If they were fictional, they would tell us nothing about the nature of God any more than the story of George Washington chopping down the cherry tree tells us anything about Washington himself. Fictional stories do, indeed, help us explain concepts, but those concepts must pre-exist the story. First we must know what God is like, and we know what He is like by reading about what He did; not some fantasy of what He might have done given a particular situation. Once we know what God is like, fiction and parable are then useful.

So our understanding of God relies on the accuracy of the Bible. And archeology just keeps showing that to be true.

Adult Stem Cells: The Trend Continues

This article at Life News describes recent grants & prize money that went to stem cell research.  There is something to note about how the money way divvied up.

As noted in the earlier Lozier Institute study, the first round of grants under this category, in October, 2009, saw a marked departure by CIRM away from a funding preference for hESCR [human embryonic stem cell research] and towards adult and other non-embryonic stem cell research.

That pattern continues in the July 2012 round of grants. Of eight research projects selected, only one involved hESCs while two involved the use of fetal tissue. The others used ethically non-contentious adult stem cells or other non-embryonic approaches. Of the $150 million awarded, $48 million went to the hESC and fetal tissue projects; the remaining $102 million went to the ethically non-contentious adult stem cell and other non-embryonic projects.

Results are drawing the funding, not political hype, and the trend is away from embryonic stem cells.

The "Godfather of Global Warming" Shuns Alarmism

No, not Al Gore.

Lovelock is a world-renowned scientist and environmentalist whose Gaia theory — that the Earth operates as a single, living organism — has had a profound impact on the development of global warming theory.

Unlike many “environmentalists,” who have degrees in political science, Lovelock, until his recent retirement at age 92, was a much-honoured working scientist and academic.

His inventions have been used by NASA, among many other scientific organizations.

Lovelock’s invention of the electron capture detector in 1957 first enabled scientists to measure CFCs (chlorofluorocarbons) and other pollutants in the atmosphere, leading, in many ways, to the birth of the modern environmental movement.

But this father of a movement has some scolding for his children. In a previous interview, he noted, “the problem is we don’t know what the climate is doing. We thought we knew 20 years ago.” This was in acknowledgement of the fact that global temperatures just haven’t gone up the way the computer models predicted. Acknowledging that error is certainly a step in the right direction, but let’s not forget that the massive drain on our economy that Greens the world over would have wanted to implement based on those flawed models would have made this recession even worse.

Now, he’s not renouncing man-made global warming, but he is asking folks who do agree with him to just calm down a bit and look at some realities. His advice?

  • He’s for more nuclear power and natural gas "fracking".
  • Ratchet back the whole green "religion" guilting.
  • Modern economies will not be powered by windmills and "so-called ‘sustainable development’." That is "meaningless drivel".
  • No, the science isn’t settled. That’s not how science works.

Friday Link Wrap-up

Yeah, haven’t posted in a while. I’ve been working on another side project that may or may not pan out. We’ll see. In the meantime, it’s time to play some catch-up on the wrap-up.

No, I don’t believe Obama was born in Kenya, but he certainly let that image get out years ago, and only recently stopped that. As late as 2004, even the Associated Press was referring to "Kenyan-born" Barack Obama. Laugh all you want at the birthers, but they at least had this sort of thing to back them up (for a while).

The Family Research Council has a count of the number of states that have legislated against same-sex marriage. Depending on how you choose what kind of legislation (law, constitutional amendment, etc.), the number changes, but here’s the biggie. "Number of states which currently (May 2012) grant marriage licenses only for unions of one man and one woman:   44" Remember that when you see polls about what people supposedly think about it.

And don’t try to press Martin Luther King into service to that particular cause. He followed his religion in this regard.

“The Iranian nation is standing for its cause that is the full annihilation of Israel.” Their words.

Civility Watch: "Union Leader Takes Bat to Pinata Depicting Gov. Nikki Haley (R-S.C.)"

Michael J. Fox realizes that stem cells, as good as they are, were never some magic cure-all.

Advances in the war:

A record-low 41 percent now identify themselves as “pro-choice,” down from 47 percent last July and 1 percentage point down from the previous record low of 42 percent, set in May 2009. As recently as 2006, 51 percent of Americans described themselves as “pro-choice.”

And speaking of the war, the actual, physical war on women by Planned Parenthood gets exposed by hidden camera videos. Predictably, the media yawns.

Further, "Congressional Black Caucus Upset By Pro-Life Black Americans". Those tolerant folks.

The Washington Post took 20 years to realize that Dan Quayle’s argument against the TV show Murphy Brown was right. It took Candace Bergen 10 years herself. And of course some of us knew that from the beginning.

And finally, oh, that liberal media.

Could Stem Cells Become Moot?

Medical technology is reducing the need for stem cells.

In the laboratory skin cells were treated with a virus, which was modified to ‘infect’ them with agents that function to convert the skin cells into precursors to brain cells. These cells can specialise into the three types of brain cell: neurons, oligodendrocytes and astrocytes. After laboratory research was carried out, the converted cells were injected into the brains of mice. These mice were bred to lack the protein myelin, which is important in aiding the transmission of messages in the brain. 10 weeks later, the precursor cells had specialised into oligodendrocytes, which made the myelin that the mice lacked.

Skin cells directly to brain cells, do not pass Go, do not create ethical issues. (And creating myelin, which is something that someone like me with MS raises their antennae over.)

The Ethics of "After-birth Abortions", Part 2

[Please click here for part 1, as this just picks up where that left off. Also, another blogger found the article again at a new URL on the same site. I’d searched using their advance search form with no success, but glad that it’s back so people can read the whole thing.]

The newborn and the fetus are morally equivalent

The authors, Alberto Giubilini and Francesca Minerva,  start this section with their definition of personhood.

Both a fetus and a newborn certainly are human beings and potential persons, but neither is a ‘person’ in the sense of ‘subject of a moral right to life’. We take ‘person’ to mean an individual who is capable of attributing to her own existence some (at least) basic value such that being deprived of this existence represents a loss to her.

Thus, to be a person, you have to know you’re a person and be able to value it. The state of not knowing, however, lasts quite a bit beyond newborn status. The authors, again, fail to address this. More than fail to, actually, they refuse to address it, as we shall see.

Merely being human is not in itself a reason for ascribing someone a right to life. Indeed, many humans are not considered subjects of a right to life: spare embryos where research on embryo stem cells is permitted, fetuses where abortion is permitted, criminals where capital punishment is legal.

The equivalence here is somewhat flawed, not the least because they start to blur the moral right to life with the legal right to life. Further, they equate giving up your legal right to life (by, for example, murdering someone else) with a fetus or embryo being in the wrong place at the wrong time. Depending on your morals, all three examples have a moral right to life, it’s just in the last case it was actively forfeited.

The Ethics of "After-birth Abortions", Part 1

Last Friday, I noted in my Friday Link Wrap-up "Medical "ethicists" are seriously arguing that post-birth newborns are ‘not persons’ and can ethically be "aborted". I also posted this article on Facebook, and one of my friends took me to task on it. He said that "sloppy agenda laden journalism" has misinterpreted their intent, and that "the researchers are attempting to provoke debate on the ethics of abortion, not the desirability to kill newborns."

I’ve read the whole piece by Alberto Giubilini and Francesca Minerva, and I come to the conclusion that, while their stated intent may not be to suggest that it is desirable to kill newborns, the result will be the same. The main problem I see is that, while they have their personal moral stances regarding how often and in what circumstances what they call "after-birth abortions" would take place, their stances would not be what others use to make their determination. Would they accept a gun manufacturer’s statement that "I don’t intend my product to kill innocent people"? Perhaps not, but it can be used that way, and abortion kills millions upon millions because they are merely inconvenient. The authors’ morals will not be used to put into practice their suggestions. Keep that in mind.

(Note: While putting this blog post together, the article was removed from the Journal of Medical Ethics website. The link takes you to a "Not Found" page, and no amount of searching for title, text, or authors could find it. I’m not sure if it was taken down for some reason, or if, perhaps, only the most recent articles appear on the website. In any event, the article is no longer there. I’ll continue to look to see if it gets posted elsewhere.)

(Second note: This is why I haven’t posted anything this week so far. I’ve been spending my time working on this.)

NASA thinking about an Earth-Moon-Libration Point 2
Well it’s not quite Space 1999, but pretty cool nonetheless,

NASA is pressing forward on assessing the value of a “human-tended waypoint” near the far side of the moon — one that would embrace international partnerships as well as commercial and academic participation, SPACE.com has learned.

According to a Feb. 3 memo from William Gerstenmaier, NASA’s associate administrator for human exploration and operations, a team is being formed to develop a cohesive plan for exploring a spot in space known as the Earth-moon libration point 2 (EML-2).

NASA taking stock of Eart’s melting land ice
From the 2003-2010 observations,

The total global ice mass lost from Greenland, Antarctica and Earth’s glaciers and ice caps during the study period was about 4.3 trillion tons (1,000 cubic miles), adding about 0.5 inches (12 millimeters) to global sea level. That’s enough ice to cover the United States 1.5 feet (0.5 meters) deep.

Yikes! That’s very unsettling news.

Yet, another report headlines us to the news that Earth’s Polar Ice Melting Less Than Thought. An excerpt (emphasis added),

Nearly 230 billion tons of ice is melting into the ocean from glaciers, ice caps, and mountaintops annually—which is actually less than previous estimates, according to new research by scientists at the University of Colorado, Boulder.

Further in the US News report researcher John Wahr states (wisely, in my opinion),

“Even with an eight-year estimate, it’s not clear how far into the future you can project,” he says. “A lot of people want to predict into the end of the century, but I think it’s too dangerous to do that … We don’t have enough info to know what’ll happen. There’s some ebb and flow to these things.”

Indeed, if anyone ever wants to sell you something now based on a prediction of what will happen 100 years from now, you’d better grab hold of your wallet (I think Michael Crichton said that). From the NASA news release, after they’ve admitted the same as the US News report, it reads,

One unexpected study result from GRACE was that the estimated ice loss from high Asian mountain ranges like the Himalaya, the Pamir and the Tien Shan was only about 4 billion tons of ice annually. Some previous ground-based estimates of ice loss in these high Asian mountains have ranged up to 50 billion tons annually.

Ouch!

Imagine if you had some remodeling work done on your home and the contractor estimated it would cost $50,000 but the final bill came in at only $4,000? Well, of course you’d be ecstatic, but wouldn’t you also be wondering why the contractor was so inept? Or what if a stockbroker claimed an investment would return $50,000 but it only came back with $4,000?

Yet we’re supposed to based governmental subsidies, regulations, etc., all on long-range “scientific” esitmates that, quite frankly, are “dangerous” to do.

Cloning Pioneer Says "Abandon Embryotic Stem Cell Research", Planned Parenthood Says "Keep Sex- and Race-Selection Abortions"

This should carry more weight than, say, someone like me suggesting it.

The scientist who led the team that cloned Dolly the sheep has urged fellow researchers to forego embryonic stem cell research — which he says is fraught with practical problems — and pursue more promising types of research.

That’s because he believes other research likely will overtake embryonic stem cell research.

Ian Wilmut spoke to a crowd of stem cell researchers Nov. 29 in La Jolla, Calif., telling them that because embryonic stem cells tend to lead to tumors, scientists should spend their time on non-embryonic forms of research, particularly on a new method called direct reprogramming. In direct reprogramming, scientists avoid stem cells altogether and, for instance, reprogram a skin cell directly into a nerve cell. Researchers have had success doing just that with lab mice. It has the support of ethicists who have opposed embryonic research.

"I’m not quite sure why this hasn’t been pursued more actively," said Wilmut, who led the team that cloned Dolly the sheep in the 1990s.

Follow the money, Mr. Wilmut. I have a feeling not even your credentials are enough to get this to happen. But we can keep trying.

The thing is, there is a vastly superior option, with none of the ethical or moral issues.

Wilmut’s speech was reported by the North County Times (Escondido, Calif.), which paraphrased him as saying direct reprogramming would provide the benefits of embryonic stem cell research without the risks. The government, he added, likely won’t spend money on embryonic research if a safer method is available.

If successful, direct reprogramming would turn the political and ethical debate upside down, making moot discussions over which types of stem cells are most promising. Wilmut was speaking in the same state where California voters in 2004 approved a 10-year, $3 billion investment into embryonic stem cell research. No cures have been found.

With embryonic stem cell research, scientists try to take stem cells from embryos and turn them into specific cells for the body. The process is opposed by pro-lifers because it destroys the embryo. In direct programming, scientists — in theory — would take a skin cell and simply reprogram it into, say, a nerve cell, without involving either embryos or stem cells of any kind.

In the results of one mice lab experiment released in 2010, fibroblast cells — found in connective tissue — were reprogrammed into nerve cells.

But again, it’s not about the science. It’s about the money that some companies want from the government. It’s also about the politics of abortion, attempting to soften the issue of killing a child with the thought that the stem cells might help someone. But the reality is, a child is still dying, and the harvested stem cells are full of problems.

And speaking of abortion, there’s a bill going through Congress that would ban abortions for the purpose of sex selection and based on race. But the opposition to this bill by Planned Parenthood, NARAL, the ACLU and others shows that their supposed concern for non-discrimination doesn’t apply to the most vulnerable of us all.

As members of Congress hold a hearing today on legislation that would ban sex-selection abortions and abortions done if the unborn child is of a specific race, leading pro-abortion advocacy groups are strongly opposed to it.

Their opposition could explain why organizations like Planned Parenthood, NARAL and the ACLU almost never speak out against the horrible human rights abuses associated with the one-child policy in China – ranging from sex-selection abortions, to forced abortions, to coercive sterilizations and infanticides.

As members prepare to hear from experts on how the sex-selection abortion culture has made its way from nations like China and India to the United States, according to one study, Planned Parenthood, NARAL, ACLU and a total of 30 pro-abortion groups banded together for a letter opposing the legislation, the Prenatal Nondiscrimination Act.

Feminists are up in arms about sex-selection abortions. OK, sorry, that was some wishful thinking. They ought to be, but aren’t.

Pro-life blogger Rebecca Taylor has noted that feminist groups frequently remain silent on the issue of sex-selection abortions.

“One may ask where are the feminists in the face of this disastrous practice that marginalizes all women?  Where are the champions of women and their reproductive rights?  They are mostly silent,” she said. “They championed choice and now that choice is being used to kill millions of female fetuses and subjugate women, they have nothing to say lest the sacred abortion cow be slaughtered.”

The principles upon which the Left stands, especially regarding science, ironically, are mostly politically convenient ones that fall away when the politics don’t work for them. Which suggests that they aren’t really principles at all.

Vatican Back Stem Cell Research!

To those in the mainstream media, and those not paying attention (typically because they read only the mainstream media), this might be shocking. However, as GetReligion.org points out, it’s rather something of a yawner; the Catholic Church has always supported stem cell research. It’s just that the media conflate embryonic with adult stem cells so often, that to the casual reader it might indeed come as a surprise.

Terry Mattingly has the analysis. His group blog documents how the press covers religion. I’ve put this blog in my list to keep up with, and you should too.

One Less Reason to Use Embryonic Stem Cells

A new study says that adult cells induced to become like embryonic stem cells ("induced pluripotent stem cells") are very nearly identical to the embryonic ones.

A study released Sunday shows embryonic stem cells and induced pluripotent stem cells are almost identical.

Since human IPS cells were first produced from mouse cells in 2006 and from human cells in 2007, it has been thought they were equivalent to embryonic stem cells, which are controversial because they are derived from human embryos.

But new research, directed by Josh Coon, a UW-Madison associate professor of chemistry and biomolecular chemistry, shows the proteins in the two types of cells are almost identical.

Stem cells have the ability to develop into any of the different types of cells in the body. In many tissues they serve as a sort of internal repair system, dividing to replenish other cells.

There is really no longer any ethical or scientific reason to use embryonic stem cells. But scientists will continue to try, and to justify it ethically. Some do this by, ironically, casting moral aspersions on those of us who bring up the ethics issue. Writing at the First Things blog, Wesley Smith responds to a faculty level scientist at UC Davis who got upset at one of Smith’s articles on the ethics issue. It is amazing how tone-deaf some of these fellows can be. One imagines that if, someday, we were able to extract perfect stem cells from pine needles, they’d still insist on using embryos.

More Good News on the Stem Cell Front

Adult stem cells, that is.

While highly potent embryonic stem cells are often the subject of ethical and safety controversy, adult-derived stem cells have other problems. As we age, our stem cells are less pliant and less able to transform into the stem cells that science needs to find breakthrough treatments for disease.

An exception to this can be found in the stem cells of oral mucosa, the membrane that lines the inside of our mouths. These cells do not seem to age along with the rest of our bodies. In his lab at Tel Aviv University’s Goldschleger School of Dental Medicine, Prof. Sandu Pitaru and his graduate students Keren Marinka-Kalmany, Sandra Treves, Miri Yafee and Yossi Gafni, have successfully collected cells from oral mucosa and manipulated them into stem cells.

Wounds in the mouth don’t scar; they heal by regeneration. The reasons for using embryonic stem cells keep dwindling.

When Does Human Life Begin?

I came across this article yesterday on the Science 2.0 website, with a very honest title; "I confess: I don’t know when human life begins". Paul Knoepfler, Associate Professor of Cell Biology and Human Anatomy at UC Davis School of Medicine, walks through all the stages of gestation and does, however, come up with his reasons for when life doesn’t begin. Before that, though, he goes through a list of three main authorities on when it begins; those with moral authority, doctors, and scientists. He argues that none of these folks have "the answer" that applies to everyone, but that seems to suggest that we get to define when life begins rather than life defining itself.

Religious commandments or cultural norms really don’t determine when life begins; they only generalize about when people should treat life as having begun. (He touches on that on his own blog.) That is not the same question as when life truly begins, but lacking that knowledge, we do need some sort of dividing line. He argues that science really doesn’t, and perhaps can’t, answer that question. At this point in our scientific knowledge, I tend to agree, especially since the question of what "life" actually is is still quite a mystery. Hence, we can only, at this point, decide when to treat life as having begun. Those aforementioned commandments and norms were instituted long before we knew what we now know about what’s going on in the reproductive cycle, and our new knowledge should inform our decisions, should it not?

In 1998 I wrote an essay, "Just One Question", which gave my take on the topic, especially as it related to abortion. My personal opinion in that was that life begins at conception, and I set out my arguments for it. (This was the culmination of a debate, 5 years earlier, on a local computer bulletin board system; the internet before there was The Internet.) Some of my points here will come from that.

Knoepfler talks about 6 main possibilities when when life might start: "(1), before conception (yes, you read that right), (2) at conception, (3) at implantation, (4) when distinctively human, organized brain activity begins, (5) when the fetus can survive outside the womb, and (6) at birth. "

Space Shuttles, Manned Space Flight, and Concrete Boats

The Space Shuttle ended a 30 year run of launches, today, with its final launch at Cape Canaveral. Is this the effective end of government sponsored manned space exploration? Despite the euphoria of the 1960s, what with the Mercury, Gemini and Apollo missions geared to get us to the Moon before the Soviet Union, and along with it an implausibly fictional dream of exploring the universe, we are left with the potential prospect of sending robotic rovers to boldly go where no man has gone before. In 1967 we were dreamers: dreaming of Pan Am passenger shuttles, transporting people to operational Lunar Bases by 2001, or of moving past the speed of light to meet up with Vulcans in the 23rd century. Yet the laws of physics (and economics) are unmoving reality checks, and it appears that where no man will ever get to where no man has gone before.

Yet, despite the silliness of some of our predictions, hopes, and dreams over the past 50 years of manned space travel, I think it’s interesting to note the changes that have occurred between the first and last Shuttle launches. Consider that at the first launch of the Shuttle, in 1981, there were no laptops carried by the astronauts, indeed, there were no laptops at all! The digital cameras they now use to record images and video were also nonexistent. If an astronaut desired to carry a portable music device onboard in 1981, it would have been a Sony Walkman and it would have played cassette tapes. Of course, now an astronaut can slip an iPod in his pocket and carry thousands upon thousands of songs. Or consider the changes in video conferencing, e-mail, cell technology, as well as the computer processing power needed for virtually all of these advancements.

Still, there is a sense of loss as we bid farewell to this part of our history – a decidedly 20th century aspect of history. Will the future of manned space travel move from government funding to that of private enterprise? If so, what are we to make of such a transition? It might end up that such a venture will be an example of how, save for political or national security issues, government is best left out of areas which private enterprise is fully capable of handling.

I leave you with a song, penned by Kate Campbell, comparing the building of a concrete canoe with the first end of the space program…

Bud’s Sea-Mint Boat
by Kate Campbell

He lived his life
A civil service man
Designing toilets
For the space program
He believed
If we could go to the moon
There’s nothing on Earth
A man can’t do

So he ordered a ton
Of sand and clay
In his front yard
He built a frame
Most folks said
It’ll never float
Still they came to see
Bud’s cement boat

A dream is anything
That you want it to be
For some it’s fame and fortune
But for others concrete
Sometimes you just
Gotta follow your heart
No matter where it leads

He gave up fishing
And most of his friends
Worked all night
And every weekend
But he didn’t mind
The sacrifice
Cause he’d build a boat
That’s one of a kind

Well the neighbors thought
It was a real eyesore
They’d say hey Bud
What are ya building that for
And knowing they would
Never understand
He’d just smile and say
Because I can

Well he got laid off
In seventy-four
And they don’t go
To the moon anymore
But down around
The Alabama coast
She still floats
Bud’s Sea-Mint boat

Rusty Nails (SCO v. 37)

Of course there are .22 caliber shotguns! The internet told me so.
A couple of years ago I overheard a recent college grad, at work, exclaim to a colleague, “What did they do before there was Google?” It seems they were searching for some elusive answer to an inquiry they had. Now, I’ll be the first to admit that I use the internet for a variety of searches, typically those involving how to get a piece of software/hardware to do what it is supposed to do. However, a good dose of incredulity is in order whenever one reads a search result on the internet. Especially from an “ehow” type site.

Case in point is the article Do You Need a Gun License for a .22 Caliber?, over at said eHow. From the article, in response to the question “What is a .22 caliber”?,

There are many types of guns that use this size ammunition; these guns include revolvers, rifles, pistols and shotguns.

Hmmm. While I suppose it is possible to build a .22 shotgun, it seems to be pretty much a one-off.

Also,

To own a .22 caliber, it is necessary to complete a Federal Firearms License application.

Well… you purchase a firearm (regardless of whether it’s a .22) through an FFL dealer.

And,

You must submit this form to the AFT (Bureau of Alcohol, Tobacco, Firearms, and Explosives.)

C’mon. AFT? Try ATF (which kind of corresponds to Alcohol, Tobacco and Firearms).
