More Stem Cell News

Stem cells have been used to help reverse paralysis in rats.

The study, headed up by Miodrag Stojkovic, deputy director and head of the Cellular Reprogramming Laboratory at Centro de Investigacion Principe Felipe in Spain, involved transplanting so-called progenitor stem cells from the lining of rats’ spinal cords into rodents with serious spinal cord injuries.

The rats recovered significant motor activity one week after injury, Stojkovic and his co-authors wrote in the Jan. 27 early online edition of the journal Stem Cells.

The researchers say the new rat results “open a new window on spinal cord regenerative strategies.”

These are great results, of course. But we all know what’s going to happen now. Those who are motivated by magic will claim this somehow proves embryonic stem cells are not needed. It, obviously, does not, but some people give extra respect to certain blobs of differentiated cells. The reason why is jarbled and arbitrary. On the upside, however, is the fact that the U.S. no longer has an anti-science administration in place, so the cries of the religious aren’t going to be heard quite so well, at least on this subject.

Oh, right. In every other ceremonial service from inauguration day.

Embyonic stem cells

The FDA has approved a study which will inject embyonic stem cells into humans.

The Geron corporation announce the approval today. The therapy used in the study is designed to treat spinal cord injuries by injecting stem cells — which are able to transform into the many different types of cells we need in our bodies — directly into the patients’ spinal cords.

The U.S. Food and Drug Administration (FDA) granted clearance of the company’s application for the clinical trial of GRNOPC1 in patients with acute spinal cord injury.

“This marks the beginning of what is potentially a new chapter in medical therapeutics – one that reaches beyond pills to a new level of healing: the restoration of organ and tissue function achieved by the injection of healthy replacement cells,” said Geron’s president and CEO. Dr. Thomas B. Okarma.

“The neurosurgical community is very excited by this new approach to treating devastating spinal cord injury,” said Dr. Richard Fessler, a professor of neurological surgery at the Feinberg School of Medicine at Northwestern University.

While, according to the article this doesn’t have much to do with the recent shift from hating science and its beauty to embracing truth (the shift from Bush to Obama), it is pretty exciting. Stem cells are wonderful things. If some major theraputic treatment does not arise out of these cells, I’ll be awfully surprised (and the scientific community). I think it may be safe enough to say if many treatments do not come from stem cells, the surprise will be huge around the world. These far-from-conscious cells are the future of medical science.

Charles Darwin and slavery

There’s a new book due out about why abolitionism played an influence in the work of Charles Darwin. It’s written by historians of science Adrian Desmond and James Moorehave.

We are not trying to explain away all of Darwin’s work as being due to his passion for emancipation, but our argument is that his passion for racial unity is what drove him to touch this untouchable and treacherous subject

This sounds like it could be a fairly interesting idea Desmond and Moorehave have here. While it isn’t necessary to show that evolution is not about eugenics and other nonsense as presented by dishonest creationists (sorry about the reduncancy) through something like this, the truth is important.

Darwin, of course, did hold many of the prejudices of his day. But if this book is right, it appears he was of a more modern mindset than previously thought.

In other news, some reporters can be dumb.

The historians wanted sexual selection was responsible for differences in appearance between races of both animals and humans.

In the theory of sexual selection traits seen as desirable but which give no competitive advantage to a species are passed down through generations.

Aside from the first sentence being, um, not a sentence, sexual selection doesn’t seem terribly relevant here. Skin color is first driven by natural selection, and then sexual selection may play a role. That explains the darker skin tones seen in societies living nearer the equator than those living in the colder climate of Europe and other similar latitudes. It isn’t that all people who see snow annually tend to get horniest when seeing light skin tones or that all people who are exposed to the sun year-long get hot and bothered over dark skin tones.

But it doesn’t end there.

‘Charles Darwin’s theory of evolution was driven by passion to end slavery’

This is the headline to the story and was probably written by the editor. I’m not sure from where it comes. Perhaps the quote of Desmond as posted above? At any rate, Darwin’s theory was driven by passion for evidence. Perhaps his desire to go into depth on certain details (human evolution, for example) was inspired by his anti-slavery stance, but the theory was not predicated on destroying any particular social institution. It was based upon evidence.

Anyway, the book comes out February 9th.

Real world results of rule internalization

Rule internalization is a horrible scourge throughout the world. It is utilizing a rule with only the rule itself in mind. Say a mother tells her daughter not to throw toys. Her daughter later throws a ball around while outside. Her mother then punishes her for breaking one of her rules. This is, of course, an absurd scenario. It is clear the reasons for the rule were that throwing toys can result in damage to the toys, hurt people in the process, and cause damage to furniture/items in the house. However, because the rule was stated more broadly than that, it technically applied to all scenarios, even throwing a ball outside. The girl violated the rule, but not the reason for the rule. This brings me to my main point.

This week, prosecutors in Greensburg, Pennsylvania charged six teens ranging in age from 14 to 17 with creating, distributing and possessing child pornography, after three girls were found to have taken photos of themselves in the nude or partially nude and e-mailed them to friends, including three boys who are among the defendants.

These are the real world results of rule internalization. This is what happens when people cease their thinking and become robotic in their ‘reasoning’.

These teenagers are not criminals. They do not deserve prison, probation, or to be designated sex offenders. Perhaps a persuasive argument can be made that they should be grounded from their cell phones, but they are not criminals. The reason for child sex offender laws is to prevent the exploitation of young individuals by older people who have some sort of authority mystique, whether it be through a job (teacher, coach) or through age – or just people who have the physical ability which allows them to act in perversion. The law was not designed to punish horny teenagers who willingly take pictures of themselves.

What’s more, in Pennsylvania “teenagers aged 13, 14 and 15 may legally engage in sexual activity with partners who are less than 4 years older”. Apparently these teenagers are allowed to have sex and, presumably, view each other naked. As soon as their nudity is placed on some sort of media device, whoa! Watch out! That violates a rule!

Authorities argue that bringing child porn charges against teens is designed to educate them about the dangers of creating and distributing such images, which could fall into the hands of commercial pornographers, pedophiles or others who might want to harm or exploit them.

That’s some pretty harsh education. “Why, Sally, I’m just trying to educate you. That’s why I am making you a felon, ruining your chances at a good college or job, and forcing you to be a pariah in society. You’re welcome.”

This argument makes no sense. Plenty of things could fall into the wrong hands. The children themselves could fall into the hands of a predator. I suppose (in the name of education, of course) children should be prosecuted for being children. That’s the only way we can prevent their exploitation.

The really disturbing thing here is that police obtained warrants to view this child pornography. Given the obvious fact that these teenagers were far from running afoul of the reason for the rule, the officers and the judge who issued the warrant should come under some scrutiny. These people went out of their way to find nude 14 and 15 year olds who may legally engage in sexual activity with the two other teenagers involved. They have no worthwhile basis for wanting to see these naked teens. If anything, that’s the most disturbing part of this all.

Family only prays for daughter; daughter dies

A wholly ignorant couple did nothing but uselessly pray for their daughter. God’s apparent response was, as has often been the case, murder.

Kara Neumann, 11, had grown so weak that she could not walk or speak. Her parents, who believe that God alone has the ability to heal the sick, prayed for her recovery but did not take her to a doctor.

After an aunt from California called the sheriff’s department here, frantically pleading that the sick child be rescued, an ambulance arrived at the Neumann’s rural home on the outskirts of Wausau and rushed Kara to the hospital. She was pronounced dead on arrival.

The county coroner ruled that she had died from diabetic ketoacidosis resulting from undiagnosed and untreated juvenile diabetes. The condition occurs when the body fails to produce insulin, which leads to severe dehydration and impairment of muscle, lung and heart function.

People like the aunt of this little girl should be praised as heroes. Her actions were unfortunately too late, but they were done with rationality and unselfishness. The parents of this little girl, on the other hand, acted without regard to reason and sensibilities. Rather than care for their daughter, they endangered her in a selfish effort to ensure themselves a place in the fictional land of heaven. People like that should be shunned from society. They are nothing but socially irresponsible. Unfortunately, it comes as no surprise that there are those who actually support such stupid actions.

A link from the site, helptheneumanns.com, asserts that the couple is being persecuted and “charged with the crime of praying.” The site also allows people to contribute to a legal fund for the Neumanns.

The Neumanns are not being “charged with the crime of praying”. They have all the freedom they could possibly desire to pray, as should be the case. What they are being charged with is the crime of indirectly causing their child’s death when they should have known better and known enough to take proper action. They do not have the freedom to be negligent parents. It just so happens their negligence came in the form of prayer.

Hopefully the other three children the article mentions the Neumanns having will not be subjected to possible death as a result of such poor parenting.

Chris Goebel, 30, a shipping department worker for a window maker, said many people in the area felt strongly that the parents should be punished.

“That little girl wasn’t old enough to make the decision about going to a doctor,” Mr. Goebel said. “And now, because some religious extremists went too far, she’s gone.”

This quote pretty much nails down the issue. These people are religious extremists. They have no right torturing their children by withholding medical care. Their actions deserve severe punishment. More importantly, their actions deserve to be recognized as activity which is to be derided and condemned as fundamentally ignorant and harmful.

Einstein on religion

I came across a quote from Einstein regarding religion and thought I’d post it here. I’ve discussed Einsteinian religion in the past.

You will hardly find one among the profounder sort of scientific minds without a religious feeling of his own. But it is different from the religiosity of the naive man. For the latter, God is a being from whose care one hopes to benefit and whose punishment one fears; a sublimation of a feeling similar to that of a child for its father, a being to whom one stands, so to speak, in a personal relation, however deeply it may be tinged with awe. But the scientist is possessed by the sense of universal causation… There is nothing divine about morality; it is a purely human affair. His religious feeling takes the form of a rapturous amazement at the harmony of natural law, which reveals an intelligence of such superiority that, compared with it, all the systematic thinking and acting of human beings is an utterly insignificant reflection… It is beyond question closely akin to that which has possessed the religious geniuses of all ages.
