They say that man's best friend is the dog, but another creature has suffered on our behalf and contributed more to our well being than all the canines ever have. The lowly mouse is so very similar to us in genes and health and disease. This similarity costs it a great deal of ill treatment. I'm not opposed to learning from animal experimentation, but I would like to believe that the usefulness of a particular animal test has been appropriately reviewed and validated.

In 2006, Daniel Hackam of the University of Toronto looked at how many animal-based experiments had been later verified by successful human trials. Out of 76 studies published between 1980 and 2000, 28 were successfully replicated in human randomised trials, 14 were contradicted in trials, and 34 remained untested. ... None of this should put a negative spin, however, on the importance of mice in research. So far, 26 Nobel prizes have gone to discoveries where research on mice has been key, including work on vitamins, the discovery of penicillin, the development of numerous vaccines and understanding the role of viruses.

So, we use them.



We freeze them for 16 years, thaw their carcass, then extract cells to clone them into new mice. (Japanese or English)
To A Mouse;
On Turning Her Up In Her Nest With The Plough
by Robert Burns in November 1785


...
I'm truly sorry Man's dominion
Has broken Nature's social union,
An' justifies that ill opinion,
Which makes thee startle,
At me, thy poor, earth-born companion,
An' fellow-mortal!
...
But Mousie, thou are no thy-lane,
In proving foresight may be vain:
The best laid schemes o' Mice an' Men,
Gang aft agley,
An' lea'e us nought but grief an' pain,
For promis'd joy!

We inspire creativity by encouraging people to build a better mouse trap.


We use them as hosts for our parasitic additions to their bodies, like this cow cartilage shaped into a human ear configuration.

In the interest of science, of course, we even levitate them by lifting magnetically every molecule of water in their body.


And yet... and yet... every once in a while, this timid relative of ours (who looks more like the first mammal than we ourselves do) can surprise us when it's driven by bravery or curiosity or plain old-fashioned hunger.


I hope that we can accumulate sufficient knowledge to eventually make live animal testing unnecessary. I hope we reach a point where we can turn the animals loose and thank them for their generations of service. Although they'd likely not understand the gesture (Rats of NIMH excepted?), perhaps we could still hold a small ceremony to commemorate that their descendants are finally free from such poor treatment. I hope we can keep an accounting and someday provide to them the same medical benefits that they have provided to us.

It was 5 years ago (2004 September 13) that I found a story about researchers at Columbia University (City of New York) producing mice with autistic behaviors by injecting them with thimerosal.   I suspected that the mice in such experiments would be killed in order to examine their brains post mortem. Just in case, though, I emailed the researcher to offer my services to coordinate a "mouse relocation program". If any mice survived their experiments and were no longer of use to the scientists, I would pay to ship them to new adoptive homes. I was willing to adopt the autistic mice similar to the way that used greyhound dogs are rescued from their industries too. Patricia Clark offered to adopt a pair of them, if I ever got my relocation program running. I never heard back from the researcher, unfortunately.

I make no apologies for myself having descended from omnivores. My diet already leaves me short of appropriate B12 resources. I will continue to eat animals, although I'd rather pick genetically engineered berries that alone can meet all of my nutritional needs. Even if someone finally engineers such a plant, how will we determine the safety of these berries in the human diet?

Before any human, of course, we will feed such berries to a mouse.

I have inconsistencies of thought on the matter, so obviously I need to spend more time pondering the subject.  By my definition, a warrior is someone willing to die, not someone willing to kill.  I respect the warriors of peace.  What, though, do I call those who do both?  I think, in particular, of the Sacred Band of Thebes... the famous warrior lovers.  What are they, in my vocabulary?  I don't yet know.

Probably the most significant religious text that I have is this:
The right to live is tentative. Material things are limited, though the mind is free. Of protein, phosphorus, nor even energy is there ever enough to slake all hungers. Therefore, show not affront when diverse beings vie over what physically exists. Only in thought can there be true generosity. So let thought be the focus of your world.
- David Brin, my favorite sci-fi author
The universe constrains us; it imposes limits on resources (both matter and energy). I've seen no evidence that suggests a way to escape this fundamental restriction. So of course there will be conflict over resources. Gods of war (and therefore heroes of warfare) have their necessary place in the story of our lives. Every form of life competes for resources, from microscopic organisms to macroscopic biospheres. When war is called for, wage war brilliantly.

I am not a peacenik who thinks that universal love will overcome every obstacle. My universe is more complex than that. I do question, though, how to tell when warfare (killing for future protection of resources rather than for immediate food/shelter) is appropriate. Nature provides so many checks on unrestrained growth already. Starvation and disease are very effective ways to reduce a population. Do we add genocide to the mix of mechanisms only because we grow impatient with Mother Nature's pace? When is a soldier something more than just an impatient bully?
I am here. I am human. I was not born to fight you. I was born to live and be free. And this is me living and being free in the face of your teargas. I wanted to create, not just react.
- "Fierce Light", http://www.alivemindmedia.com/films/fierce-light/ (YouTube trailer)
This movie reminded me that peaceful protestors die just as simply as armed ones. Peacefully waiting out a conflict still results in casualties. Can the peaceful outlast the armed, starving the aggressor of money, time, food, or water? If they can, then isn't it the moral choice to maintain peaceful protest? Ultimately, there needs to be fewer humans on the planet than we have now. I see that goal as the only long-term solution. Surely starvation and disease can eliminate a great many people without the need for warfare. Most religions seem opposed to reducing birth rates, but the only alternative I see is the massive reduction of population by other (far more unpleasant) means.
Our minds display an enormous plasticity, and it is possible to transform ourselves based on deliberate uses of attention. And yet we need to understand that rationally.  We need to understand that neuroscientifically and psychologically.
- Sam Harris in "Fierce Light"
(This quote also reminds me that I still need to make time to write about Remaking.)

Perhaps there's a way to use ideals to inform our intellect, a way that doesn't require the use of traditional religious institutions or standards.  Sam Harris wrote a book titled, "The End Of Faith: Religion, Terror, and the Future of Reason".  Apparently he tries to posit a rational approach to ethics for people who are more familiar with religious methods.  I think maybe I should continue my investigation by ordering myself a copy of his book to read.

No answers today.  Just lots of questions.

morality and medicine

chimeraFor some people, technology seems to be a dizzying force that perpetually brings them new and previously unfathomable possibilities.  The thrashing of expectations forces them to constantly re-evaluate their understanding of the operation of the universe.  (Therefore it also threatens their understanding of God(s), therefore it is to be summarily distrusted as a destabilizing force.)

That's probably why some people are still stuck in the debate over stem cell research into conditions like Parkinson's disease.  They don't realize that they've already lost that debate and the next one too, because these processes are already producing useful knowledge about human ailments.

The "next one" debate that I mean is the creation of chimeras.  A chimera in folklore is a creature made up of several animals.  The traditional Greek example included a lion's head and body, a goat's head from the back, and a snake's tail with the head at the end (pictured here from Wikipedia).  A chimera in the medical sense is an animal whose dna incorporates sequences from other animals, particularly humans.  Human chimera also occur naturally (people have dna from two different people in them), but newly designed animal creations are the issue that I intend here.

I still think that the world very quickly needs to come up with a doctrine of species' rights.  We need to know immediately how to deal with current animals whose intelligence is frequently being revealed to be much like humans'.  We need specific thresholds of understanding (and therefore suffering) that trigger specific prohibitions against certain ill treatment.  Ill treatment is a certainty, as life is very messy, but we need to define when government will or will not become involved. Anyone can claim that their deity abhors a given practice, but I've noticed that it's generally up to humans to define when to enforce a standard.  (Deities seem to never intervene in time to prevent some impatient humans from taking matters into their own vigilante hands.)

So we need standards.  We need them yesterday.   "No" is an insufficient standard, as it's already too late and it's utterly impossible to enforce.  I think that a workable solution may involve making people responsible for the creatures they produce, just as parents are responsible for the creatures that they produce using the old-fashioned horizontal mambo.   I think the concept of chimeras is pretty cool.  I think it does provoke lots of moral questions that seriously need answers.  I'd be pleased if someday the process resulted in a creature that we could ask, "What do you think of the practice of animal experimentation?", and then we receive a thoughtful reply.

Anyway, the news that brought on this blog entry?

"Multiple sclerosis successfully reversed in animals"
http://www.physorg.com/news169211700.html

More specifically, those animals are re-introduced to their own modified chimeric blood cells.  Not true chimeras, but obviously pointing at the next step of the research, getting an animal's body to continuously produce its own cure.  They think this treatment "might also be effective against other autoimmune disorders like Crohn's disease, lupus and arthritis" and even for organ transplants.  Again, too late to have a debate about the process.  We have important medical knowledge already.  That genie isn't going back into the bottle.

For what it's worth, I would suspect (with weak conviction) that my own mother is a chimera.  She has said before that every time she's had her blood type tested, it's come back as a different type.  Chimera is one possible explanation, at least.

(p.s. Okay, it's an hour later.  I promise I'll stop repeatedly editing the original post now.  *laugh*)
mellowtigger: (the more you know)
I was wrong. Well, maybe I'm still accurately remembering what I was told at the time, but what I believed is incorrect.

cotton bollsI remember visiting relatives in Knott, Texas, in the late 1970s or early 1980s and having to drink bottled water because the well water was poison. That happened with regularity, you see, during each drought. The sinking water table would bring contaminants with it until they reached a concentration that was too dangerous for people to ingest. I remembered it as being mercury contamination... but after my recent websurfing it seems now to have been arsenic instead.  Either element is plausible considering the source of the problem.

You see, people out there are cotton farmers. In order to harvest cotton with mechanical aid, you need the plants to die and turn crisp while holding their cotton bolls out high at the end of dead stalks where the machines can pluck them. To get all the plants to conveniently die at the same time across wide areas of land... they spray defoliants. Those chemicals contain arsenic (or mercury or other unpleasant substances). Repeat this process over decades, and you can see how poisons might accumulate in the topsoil and then get dragged down to groundwater as the underground "tide" (water table) recedes.

In other words, it's our own fault. "Our" meaning my family members... and our society at large for insisting on production that happens with less time, less effort, and less cost. Short-time cost, mind you. Long-term cost isn't part of the annual equation.
"During the 1990s, some 23 confirmed cases of elevated arsenic groundwater in Howard and Martin counties near the city of Knott have been attributed to point sources such as cotton gins, gin waste, gin trash, and hull pits, among other sources."
- http://www.texasep.org/html/wql/wql_3grw_agri.html
Not exactly.  My relatives weren't by the gins; they lived (and had their well) out in the cotton fields.  The ground accumulated arsenic, so the plants accumulated arsenic.  The whole system became toxic 3 decades ago, and yet they still have people out there farming cotton by spraying defoliant.

I also found a remarkable pdf file of a chart that details many sites of groundwater contamination in the state of Texas from 1976 to 2006. ( www.tceq.state.tx.us/assets/public/comm_exec/pubs/sfr/groundwater06/06-2.pdf ) It's a scary 120 pages of documentation about unhealthy groundwater. Most of it is gasoline, but if you search for the word "Knott" (the town (sort-of town, community really) where my relatives lived) you'll find references in both Martin and Howard counties with confirmed arsenic poisoning.  Only 3 of them are listed, not the 23 locations mentioned in the previous quote.
"Injudicious application of arsenical pesticides in agricultural fields has rendered soils with elevated levels of arsenic. This is particularly true for the cotton soils of Texas where background concentrations of arsenic are significantly higher than normal."
- http://gsa.confex.com/gsa/2004AM/finalprogram/abstract_74981.htm
I can't find a reference at the moment, but supposedly this arsenic (and mercury?) remains part of the cotton fiber even after processing and is included in the shirt that you're wearing right now... unless you've already gone to organic products including your clothes.

Really, the Green Revolution can't happen fast enough for my sensibilities.

it has a name

I've been doing some websurfing to try to learn more. My economic view has a name after all. You'd never guess what it is. I was surprised when I found it.  I'll give you a hint first.
You cannot have a satisfactory society made up of competitive, self-interested individuals! In a satisfactory society there must be considerable concern for the public good and the welfare of all, and there must be considerable collective social control and regulation and provision, to make sure all are looked after, to maintain public institutions and standards, and to reinforce the sense of social solidarity whereby all feel willing to contribute to the good of all.
- Ted Trainer
Note that first sentence. Does it give you any ideas? :)  It turns out that the name I found is "Post-Autistic Economics". Imagine that! *laugh*

One group has been publishing a newsletter since 2000 September 01. So of course I expect to be doing some reading of their archives in the coming weeks. A few other people seem to have hit on the same idea, including one guy who has thoughts on how to transition from one economy to another, rather than just waiting patiently for the inevitable implosion.

The links:
http://www.paecon.net/, Post-Autistic Economics Network
(created by French economics students, later joined by Cambridge students)
http://ssis.arts.unsw.edu.au/tsw/, "The Simpler Way" by Ted Trainer
http://www.neweconomics.org/gen/, New Economics Foundation

So I'm not the only person to see the fatal flaw in any economic system based on growth.  Growth happens, and it must be accounted for in any stable economic system.  Growth is the flaw, though, rather than the salvation.  Change is the only certainty.  Growth is not guaranteed.
