Cryonics, Smallpox, and Pope Pius VII

I remember when heart transplants were front-page international news, not local human interest stories: and when oral polio vaccine replaced injections. I really do not miss the 'good old days.' I remember them, and they weren't.

I also remember when cryonics was 'science fiction stuff,' not a highly-experimental and controversial medical procedure. I probably won't live long enough to see whether it works. But if you're young enough: you might.
  1. Heart Transplant: "a Rebirth of Sorts"
  2. Cryonics: Life, Health, and Decisions
Since I'll be talking about life, death, and medical practices, I'd better start by saying that I'm a Christian: a Catholic.

Like it says in the Apostles Creed, "I believe in ... the resurrection of the body, and the life everlasting." I'll be explaining why I don't see a conflict between that belief and trying to save lives.

I had more to say after discussing the 'cryonics' news item, so this post runs a bit long:

Multiple Surgeries


By the time I started kindergarten, one operation had given me a mildly-functional left hip joint — and another had fixed a complication that may or may not have resulted from the first procedure.

Decades later, I had both hip joints replaced; carpal tunnel surgery done on both wrists: and was in the operating room again when part of my lower digestive tract went bad.

I'd probably have died if the latter had happened in the 'good old days.'

Needing hip joint replacements wasn't a surprise.

Getting a diagnosis of depression and something that's currently pegged as being an autism spectrum disorder — not so much, either, in retrospect.

I'd gradually learned that many folks transition into adolescence without having the light and color drained from their world: metaphorically speaking.

There wasn't much wrong with my vision, apart from extreme nearsightedness. I could still notice that beauty existed, and analyze the phenomenon: but the emotional responses were largely missing.

An array of powerful antidepressants and other pharmaceuticals have been changing that in recent years: which is a very nice change of pace.1

That brings up an interesting question: am I facing the wrath of God because I defied the Almighty by letting doctors keep me alive and somewhat healthy?

I don't think so.

Being Healthy


Let's back up a little, and ask another question — "is being healthy okay?"

Maybe that sounds like a daft question, or maybe not. I've run into a few excessively-sentimental 'lives of Saints' tales that focus on Saints who were very ill.

Saints are noteworthy for their heroic virtue and living in fidelity with God, not for being horribly sick, and that's another topic. (Catechism of the Catholic Church, 828)

Life and health are good things, "precious gifts entrusted to us by God:"
"Life and physical health are precious gifts entrusted to us by God. We must take reasonable care of them, taking into account the needs of others and the common good...."
(Catechism, 2288)
Maintaining health and fitness is important: but it shouldn't be the most important thing in my life. Being healthy is okay, but it's wrong "...to sacrifice everything for it's sake, to idolize physical perfection and success at sports....." (Catechism, 2289)

That seems clear enough. Being healthy is okay. Staying healthy is okay: within reason.

It's okay to help sick people get better, too, and find new ways to cure disease. It's even okay to transplant organs, providing we don't kill or maim one person to help another. (Catechism, 2292-2296)

Even if a disease or injury would eventually kill me, medical treatments — including painkillers — are okay: within reason. (Catechism, 2276-2279)

Using our Brains



(From Correogsk, via Wikimedia Commons, used w/o permission.)

I occasionally run into news about someone who decides that getting medical treatment is immoral. If the person is Christian, the idea often seems to be that we can either use our brains or trust God: not both. Or maybe it's that being sick is divinely ordained punishment.

I trust God and use my brain, or try to; and don't think God gave me bad hips and glitchy neurochemistry as a punishment.

I'd better explain that, or try to.

After the Eden incident, our mental picture of God has been distorted.2 (Catechism of the Catholic Church, 396-401)

Maybe life would be easier if God treated us like Pavlov's dogs, promptly smiting 'sinners' and rewarding good behavior with yummies. But that's not how it works:
"But I say to you, love your enemies, and pray for those who persecute you,

"that you may be children of your heavenly Father, for he makes his sun rise on the bad and the good, and causes rain to fall on the just and the unjust."
(Matthew 5:44-45)
Then there was the way Israel treated his youngest son, Joseph, and Joseph's behavior, that got him sold as a slave and shipped to Egypt. A few years later, he was running the place: and a good thing, too, as it turned out. (Genesis 37:2-28; 45:5-8)

I accept the idea that my continuing existence depends on God. (Catechism, 301)

But I also must accept the idea that God made a world where the creatures in it — including me — play a role in making things happen. (Catechism, 306-308)

Thinking, making decisions based on reason, is part of being human. I can decide to let whim and emotion guide me, or use my brain. Thinking is an option, not a requirement. (Catechism, 154-159, 311, 1730, 1778, 1804, 2339)

My experience has been that thinking before acting is a good idea. (December 6, 2015; March 1, 2015)

Basically, I'm expected to keep myself healthy: within reason. (Catechism, 2288-2289)

Beware Tiny Cows!



(From James Gillray, H. Humphrey, Anti-Vaccine Society; via Wikimedia Commons; used w/o permission.)
"The Cow-Pock—or—the Wonderful Effects of the New Inoculation!"
(James Gillray's warning against the perils of preventing smallpox. (1802))

Concern, reasonable and otherwise, over new medical technology is nothing new.

For example, in 1802 James Gillray warned the British public against a controversial medical technology: inoculation. Meanwhile, the London Fever Hospital opened, "to the great horror of the neighbours." It was the first voluntary fever hospital, and that's yet another topic.

James Gillray probably realized that using cowpox inoculations to prevent smallpox wouldn't really make little tiny cows burst from the nose, face, and assorted other embarrassing spots. He was a cartoonist, satirist, caricaturist, and arguably invented the political/editorial cartoon.

That may explain what looks like a copy of Nicolas Poussin's "Adoration of the Golden Calf" on the back wall of that inoculation party.

The golden calf incident, described in Exodus 32, happened while Moses was on Mount Sinai. It was a major violation of the Decalogue, and they really should have known better. (Exodus 20:4-6)

Idolatry, putting anything ahead of God in my priorities, divinizing what is not God, is still a very bad idea.3 (Catechism, 2112-2114)

Where was I? Smallpox, inoculations, tiny cows, idolatry. Right.

Vaccination against disease has a long history — I'm putting a resource link list near the end of this post4 — but in the 1700s it was still experimental medicine, and very dangerous.

Science and Silliness


We've lived with, and died from, smallpox for a long time: upwards of three millennia, most likely.

Egypt's Ramses V, Lady Mary Wortley Montagu, and millions whose names are not remembered, suffered from the disease. (February 12, 2014)

Smallpox wasn't always fatal. About two of every three who caught the worst sort didn't die: but were scarred for life.

One of the few advantages to surviving smallpox was that it didn't strike the same person twice. Somewhere along the line, folks also noticed that the disease wasn't as severe for those who caught it from a contaminated break in the skin.

That practical observation led to variolation, deliberately infecting someone so that their bout with smallpox was more survivable, which reduced the smallpox death toll. It was an early step on the road to contemporary medicine.

I don't recall anyone objecting when the United Nations declared that smallpox was extinct on May 8, 1980.

But in the "good old days" when folks like Edward Jenner were developing inoculations against smallpox, it was a different story. Vaccination experiments triggered strong reactions, sensible and otherwise:
"for a man to infect a family in the morning with smallpox and to pray to God in the evening against the disease is blasphemy; that the smallpox is a judgment of God on the sins of people, and that to avert it is but to provoke him more; that inoculation is an encroachment on the prerogatives of Jehovah, whose right it is to wound and smite."
(Contemporary reaction to inoculation experiments by American physician Dr. Zabdiel Boylston, circa 1720)

"Smallpox is a visitation from God; but the cowpox is produced by presumptuous man; the former was what Heaven ordained, the latter is, perhaps, a daring violation our of holy religion."
(A physician's reaction to Dr. Edward Jenner's experiments in developing a vaccine for smallpox, (1796) via Psychological Sciences, Vanderbilt University)
Let's see what other folks said about the newfangled sort of medicine:
"...In contrast, many village priests in Italy, Germany, Switzerland, and England not only urged parishioners to seek the preventative treatment, they became wholesale vaccinators themselves. Pastors in Bohemia charged parents with responsibility 'before God for neglecting the vaccination of their children.' In 1814, the Pope himself endorsed vaccination as 'a precious discovery which ought to be a new motive for human gratitude to Omnipotence.'..."
("Deliberate extinction: Whether to Destroy the Last Smallpox Virus," pp. 19-20, David A. Koplow, Georgetown University Law Center (2004))
That would have been Pius VII who said vaccination was "a precious discovery which ought to be a new motive for human gratitude to Omnipotence."

I'm inclined to think he was right.


1. Heart Transplant: "a Rebirth of Sorts"



(From Lutheran Health Network, via WANE News, used w/o permission.)
(Heart transplant recipient Michael Steadman)
"Heart transplant is a rebirth of sorts for Fort Wayne man"
WANE Staff Reports (April 25, 2016)

"Whether it’s taking a walk in the park, spending time with his grandson, and even performing household chores, Michael Steadman is cherishing every experience.

"Steadman’s heart began to fail three years ago. He got weak, could barely climb the stairs, and was exhausted all the time. Things gradually got worse, and last year doctors told him he’d need a transplant. He expected to be on the waiting list for months – maybe even years – but within 5 days he got the call.

"That was in July of 2015. He’s still on the road to recovery and doing everything he can to stay active and healthy...."
Open heart surgery was newsworthy when I was in high school: and Christiaan Barnard's successful human-to-human heart transplant in 1967 was a major international story. I trust that the donor really was "essentially brain dead" when the doctor cut her heart out.

Louis Washkansky survived the operation and lived for another 18 days: before dying of pneumonia.

I could claim that a wrathful God smote Mr. Washkansky something fearful for being a terrible sinner and mocking God by surviving the operation: but I won't.

I think he caught pneumonia and died because immumosuppresive drugs had shut down his immune system.

Transplant rejection4 is one reason I think learning to grow our own replacement organs is a good idea, and that's almost another topic. (August 29, 2014)

I could also denounce WANE, the transplant team at Lutheran Hospital, and Mr Steadman, for their "encroachment on the prerogatives of Jehovah," as Dr. Zabdiel Boylston put it in the 1700s. But I won't.

I see the WANE headline,"Heart transplant is a rebirth of sorts for Fort Wayne man," as a mildly-poetic way of expressing the idea that getting a new heart restored at least a porton of Mr. Steadman's health.

As I said earlier, organ transplants are okay: providing we don't kill or maim one person to help another. (Catechism, 2296)

Revenge of Frankenstein's Son's Sister's Cousin


That 'rebirth' headline is mild, compared to its 'dead patient returns to life' counterparts I remember from the late 1960s.

They were almost accurate, since a common way to tell if someone was still alive was to check for a pulse.

Surgeons couldn't operate on a beating heart, so the organ had to be stopped — and the patient was "dead." At least in the pulse = life sense.

I'll get back to that.

Oddly enough, I don't remember a rash of horror-heart-transplant movies in the wake of Dr. Barnard's accomplishment.

"Parts: The Clonus Horror," 1979, was close; and considerably more plausible than the 1991 "Body Parts."

Maybe studios figured folks had had their fill of Frankenstein spinoffs5 by then, or maybe I didn't notice 'I Have an Ax-Killer's Heart' titles.

Anyway, that's movies; and heart transplants are now so routine that they're generally human-interest local stories.

My guess is that someone, somewhere, is preaching that the road to Hell is paved with transplanted hearts. That's a disturbing image, now that I think about it. Never mind.


2. Cryonics: Life, Health, and Decisions



(From iStock, via BBC, used w/o permission.)
("What would it be like to know that everyone you had ever met was long gone?"
(BBC))
"If cryonics suddenly worked, we'd need to face the fallout"
Rachel Nuwer, BBC Future (April 25, 2016)

"Right now, in three facilities in the US and Russia, there are around 300 people teetering on the cusp of oblivion. They exist in a state of deep cooling called cryopreservation, and entered their chilly slumber after their hearts had stopped beating. Before undergoing true cell death, the tissues of their brains were suspended using an ice-free process called vitrification. All are legally deceased, but if they could they speak, they would likely argue that their remains do not constitute dead bodies at all. Instead, in a sense, they are just unconscious.

"No-one knows if it's possible to revive these people, but more and more of the living seem to believe that uncertainty is better than the alternative. Around 1,250 people who are still legally alive are on cryonics waiting lists, and new facilities are opening in Oregon, Australia and Europe soon.

" 'We have a saying in cryonics: being frozen is the second worst thing that can happen to you,' says Dennis Kowalski, president of the Cryonics Institute in Michigan, the largest cryonics organization in the world. 'There's no guarantee you'll be able to be brought back, but there is a guarantee that if you get buried or cremated, you'll never find out.'..."
Rachel Nuwer's article mercifully avoids the "I freeze people to cheat death" and "Bringing the dead back to life" exuberance of some 'science news' coverage.

I'd have a problem with cryonics, heart surgery, and emergency rooms, if I thought being very sick or seriously injured was the same as being dead — or that folks who aren't healthy are better off dead. I don't.

Recapping what I said earlier, I see life and health as gifts from God. Taking reasonable care of them is a responsibility. (Catechism, 2288)

That's reasonable care. "Over-zealous" treatment isn't required. Common sense is:
"Discontinuing medical procedures that are burdensome, dangerous, extraordinary, or disproportionate to the expected outcome can be legitimate; it is the refusal of 'over-zealous' treatment. Here one does not will to cause death; one's inability to impede it is merely accepted. The decisions should be made by the patient if he is competent and able or, if not, by those legally entitled to act for the patient, whose reasonable will and legitimate interests must always be respected. "
(Catechism, 2278)

Legally Dead: For Now



(From iStock, via BBC, used w/o permission.)
("The bodies preserved today are considered legally dead, but our descendants might not see it that way"
(BBC))
"...To the uninitiated, cryonics might seem the stuff of 'Vanilla Sky,' 'Demolition Man,' and other purely science fiction works. But many researchers believe that it is a credible field of inquiry, and cryobiologists are slowly chipping away at the possibility of revival. Most recently, a team succeeded at thawing a previously vitrified rabbit brain. Even after several weeks of storage, the synapses that are thought to be crucial for brain function were intact. The rabbit was still dead, though – the researchers did not attempt to resuscitate the animal afterwards.

"While a thawed out rabbit brain does not a fully revitalised person make, some believe that cryogenic revival might someday be as commonplace as treating a case of the flu or mending a broken arm. 'This is really not so earth-shattering or philosophically weird as you might think,' says Aubrey de Grey, co-founder and chief science officer at the Sens Research Foundation in California, a non-profit organisation dedicated to changing the way we research and treat age-related ill health. 'It's just medicine – another form of healthcare that helps people who are seriously sick. Once you get your head around that, it's much less scary.'..."
(Rachel NuwerRachel Nuwer, BBC)
Cryonics "is not part of normal medical practice," as a Wikipedia page put it.

Quite a few scientists are skeptical about whether or not 'reviving' someone who has been frozen is possible. They've got a point.

We don't know for sure whether the human brain has to be continually active to preserve memory. If it does: getting stored at around -196°C would pretty well erase the person's memories. I wouldn't like that.

The last I heard, someone must be legally dead to be frozen. That makes sense from a criminal-liability viewpoint: but means that if and when folks get taken out of cold storage, medicos will have a really sick patient on their hands.

I'm not convinced that cryonics works, or that it doesn't. I'll get back to why I don't see an ethical problem if it does. Practical issues, yes: ethical, not so much. I'll get back to that, too, in this post's Afterword.

Death, Saving Lives, and Safety Coffins


We've been learning a great deal recently, which has helped save lives: and made defining "death" trickier.

I am convinced that "legally dead" or "medically dead" and "dead" are not the same thing.

If having a pulse meant being alive, and not having a pulse meant being dead, all recovering heart transplant patients are walking corpses that had no heart at all, let alone a pulse, for several minutes.

I think Mr. Steadman would not agree, and I think he's right.

I'll admit to having a personal bias about hasty assessments of death.

My father's father was on a construction site when a crane collapsed, killing many of the workers: including, apparently, my grandfather. An alert medic noticed that one of the mangled "corpses" was bleeding, which saved my grandfather's life.

His days as a construction worker were over, but he developed other skills, and that's yet again another topic.

I'd like to think that most folks buried these days were dead before getting embalmed/cremated and interred.

Which reminds me: I've heard that cremation was on the 'don't do this' list for Catholics. The rule wasn't as random as in might seem, and reasons for the prohibition are implicit in the Catechism's discussion of options:
"Autopsies can be morally permitted for legal inquests or scientific research. The free gift of organs after death is legitimate and can be meritorious.

"The Church permits cremation, provided that it does not demonstrate a denial of faith in the resurrection of the body.93"
(Catechism, 2301)
I've talked about autopsies and cremation before. (August 28, 2015; September 25, 2009)

I'm forgetting something. Safety coffins: that's it.

I'd like to think that what's euphemistically called "unintentional live burial doesn't happen: but in 2005 funeral director John Matarese noticed that the "corpse" in a body bag wasn't quite dead yet, and called paramedics. Dashed thoughtful of him, I think.

Quite a few patents for safety coffins date from the 18th and 19th century.

Cholera epidemics — I've mentioned how much I don't miss the 'good old days' — and a natural skittishness about examining possibly-contagious corpses encouraged not-unreasonable fears of waking up in a cozy little coffin.

"Dead," But He's Better Now


A recovery team pulled a limp, obviously-lifeless body out of the Red River in Fargo, North Dakota, back in 1987. Young Alvaro Garza Jr. was limp as a noodle when a recovery team fished him out from a hole in the ice.

He had no pulse, and was quite obviously "dead." That's what happens when you spend 45 minutes under the river's surface.

Usually.

His core body temperature went down to 77 degrees Fahrenheit — which probably saved his life. That, the mammalian diving reflex, having a hospital with a heart-lung machine nearby, and a family who wanted him to be alive. My opinion.

Folks at St. Luke's hooked Alvaro Garza Jr. into the machine, which let them "take his blood and warm it up and put it right back in his body," as St. Luke's/MeritCare's Roberta Young, RN, put it. 20 years later, Mr. Garza had four kids of his own: and a healthy respect for water.

Afterword


As I said last month, I follow the Man who is God: who died in my place; descended to the abode of the dead; rose from the tomb; and lives today and forever. (Matthew 28:1-10; Mark 16:1-11; 1 Peter 4:6; Catechism, 631-635, 638-655)

Jesus died. Our Lord had been killed by an execution squad which included Roman soldiers. They surely knew the difference between a dead body and someone who had fainted, or was pretending to be dead.

About three decades back, JAMA (The Journal of the American Medical Association, a peer-reviewed medical journal covering all aspects of the biomedical sciences) published an analysis of what our Lord went through.

It isn't an easy read, but worth the effort. My opinion:
I've been over that before. (April 5, 2015)

Health and Faith


When my lower digestive tract went into failure mode, my wife, a devout life-long Catholic, poured me into the family van and drove me to an emergency room.

I am quite sure she did not do that because she denied the Resurrection, or wanted to encroach "on the prerogatives of Jehovah, whose right it is to wound and smite," as Dr. Zabdiel Boylston put it.

I am reasonably confident that her goal was what it appeared to be: restoring my health.

Restoring and maintaining health is a good idea, within reason. (Catechism, 2278, 2288)

Getting back to the cryonics, ethics, assumptions, and all that — I very strongly suspect that whether or not getting put in cold storage is right depends at least in part on a person's motive.

If the individual thinks surviving until a cure for some disease is developed will prove that God doesn't exist — don't laugh, I've heard goofier arguments on several issues. I also don't see that as a good reason.

Someone wanting to survive until a cure for some disease is developed: that, to me, seems reasonable. I suppose someone out there thinks we're supposed to sit on our hands and let God smite us something fierce, but I'm not of that opinion.

Basically, I don't see cryonics as wrong, ethically.

If it works, it's simply another method for stabilizing a patient until adequate medical care is available. If I'm going to denounce cryonics on ethical grounds, I might as well denounce ambulances: because they defy God by getting folks to a hospital while they're still alive.

We may learn that cryonics doesn't work, and that folks who signed up to be frozen are really dead: as well as legally deceased. But right now, we do not know. I'm inclined to see it as a highly experimental medical procedure: dangerous, but potentially life-saving.

I think what Dr. Barnard wrote about Mr. Washkansky, the first heart transplant patient to survive more than two weeks after the operation, is relevant to questions about cryonics:
"...Washkansky could either wait for certain death or risk transplant surgery with an 80 percent chance of surviving. He chose the surgery. As Barnard later wrote, 'For a dying man it is not a difficult decision because he knows he is at the end. If a lion chases you to the bank of a river filled with crocodiles, you will leap into the water convinced you have a chance to swim to the other side. But you would never accept such odds if there were no lion.'..."
(Christiaan Barnard, People and Discoveries, A Science Odyssey; NPR)

The Disturbing Case of Lal Bihari


Lal Bihari was dead, officially, from 1975 to 1994. His uncle had bribed an official to register Bihari's death: putting the uncle in line to inherit some land.

Bihari eventually sorted the legal mess out, learned that at least a hundred other "dead" folks were in his position, and formed the Uttar Pradesh Association of Dead People.

Lal Biharie and his fellow-dead-people were victims of fraud: and in danger of being really, as well as legally, dead if they made too much of a fuss. I hope folks in that part of the world sort the mess out, but I won't claim that 'it can't happen here.'

Over the half-century or so that I've been paying attention, quite few definitions of brain death, clinical death, and legal death have been popping up.

"Brain death," the complete cessation of brain activity, might be a useful definition of death: if it was consistently applied.

It's not, so "brain death" in one place can mean that the whole brain, right down to the brainstem, has shut down.

Somewhere else, a patient with an active brainstem can be breathing on his or her own — and be "brain dead" because at least part of the higher brain functions are offline at the moment.

I don't think it helps that in my country organ harvesting can't start, legally, until a doctor signs off on "brain death." Cheerful thought.

Waking Up in the Future: Practical Considerations


I grew up when quite a few folks still thought human ingenuity would solve all our problems: or at least make "the future" a magical place to live.

I've seen that silly optimism change to what I think is an equally-silly fear that the future will be just simply awful: and then we'll all die.

As it is, I like living in "the future" — when polio is no longer a health threat in my part of the world, and smallpox is an extinct disease.

The World Health Organization released a Global Polio Eradication Initiative Strategic Plan progress report in 2012. This will take time, but I think we can end polio, too.

About adjusting to 'the future,' it helps that I didn't expect the world I am growing old in to be exactly like the world my grandfather lived in. I lived through the intervening years, learning new skills as needed: and enjoy learning about new technology.

If I'd — this couldn't have happened, we didn't have the technology, and still don't — been frozen in my mid-20s, and taken out of storage this year: that would be a different experience. I wouldn't mind learning that the Cold War was over: and wouldn't miss disco.

My guess is that I'd learn how to use today's information technology differently: most likely skipping right past learning how to use BASIC, QBasic, and DOS. Also, I wouldn't have gotten practice being patient while a dial-up modem made connections.

What sort of job I'd be qualified for: that, I'm not at all sure about.

The biggest adjustment, I think, would be getting used to a world without my parents. I would have missed the last few decades of their lives. On the whole, I'm glad to have experienced that.

Something that I'd wonder about, if I signed up for being frozen, is who would pay the bill if I survived the process. Cryonics organizations charge for their services up front, including storage and maintenance costs: so that's not an issue. Not in the short run, at least.

But let's assume that I was dying of something, arranged to be frozen, and woke up in the 31st century. Any financial arrangements I'd made could easily have failed in the millennium that passed.

One of my top concerns would be learning how I'd be expected to compensate folks for keeping me alive.

In a way, I'd probably rather wake up after several thousand years. That way my memories and experiences might be a mildly-valuable resource for antiquarian scholars.

And now for something completely different.

"Reanimated Abomination of Science?"


That's Rudolf Selnikov in the jar: what's left of him, that is. He was "in need of medical attention" — it's quite complicated, actually, like most of the Girl Genius comic series, and mostly irrelevant to this post.6

Selnikov looks happy in that panel because he's realized that being (officially) "dead" frees him from political infighting; and, as he put it, "...twisted and ruthless as you people are, throwing in with you is a step up."

Several panels back, Selnikov asked why he was "still alive." Given the willing suspension of disbelief required for the story — that question makes sense.

He'd been seriously injured, but "dead" only in a legal sense. His head was essentially intact, so his medical status in the story was a bit like an accident victim who was unconscious when taken to the emergency room.

We can't grow a new body for someone. Today, that sort of medical technology does not exist: although scientists have successfully grown a mouse thymus, and a few other non-human spare parts. (August 29, 2014)

Interestingly, I don't remember folks going ballistic over the first heart transplants. Maybe that's because I'd stopped listening to radio preachers by then, or maybe they were too busy having conniptions over just about everything else going on during the '60s.

By now, swapping out someone's heart is still a major medical procedure: but I think most folks have gotten used to the idea that not having a pulse does not necessarily mean being dead.

I also think the Sens Research Foundation's Aubrey de Grey, quoted in that BBC Future article, made sense, talking about cryonics:
"...'It's just medicine – another form of healthcare that helps people who are seriously sick. Once you get your head around that, it's much less scary.'..."

Flat Earth, Psalms 150:1 — and Joy


(From N. F. Gier, University of Idaho; adapted from an illustration in the New American Bible: St. Joseph Edition; used w/o permission.)
(A Mesopotamian cosmology, about two dozen centuries back.)

'The Bible says Earth is flat.'

If you live in America, and haven't heard that as a reason for rejecting Christianity: you're not paying attention.

On the other hand, word seems to be getting around that the "dark" ages were anything but.

I've discussed post-Roman Europe, science, and autopsies, before. (January 22, 2016; August 28, 2015; August 15, 2014)

About Earth being flat — I've yet to run into a Christian who says that; although I did meet one who informed me that our sun goes around Earth, not the other way around.

He had a point, given a completely deadpan reading of Joshua 10:12-13. (October 3, 2014)

Interestingly, Sacred Scripture does mention "the pillars of the earth" and "the mighty dome of heaven:"
"...For the pillars of the earth are the LORD'S,
"and he has set the world upon them."
(1 Samuel 2:8)

"He shakes the earth out of its place, and the pillars beneath it tremble.
"He commands the sun, and it rises not; he seals up the stars."
(Job 9:6-7)

"1 Hallelujah! 2 Praise God in his holy sanctuary; give praise in the mighty dome of heaven."
(Psalms 150:1)

"The angel said to me in reply, 'These are the four winds of the heavens, which are coming forth after being reviewed by the LORD of all the earth.' "
(Zechariah 6:5)
So how come I'm not ranting and raving about the evils of science, and why NASA should stop smashing space probes into "the mighty dome:" thereby risking flood and the wrath of a hypersensitive God?

I've been over that before, too. (September 6, 2015; October 16, 2015; October 3, 2014)

Briefly — poetry isn't science, and I'm a Catholic who knows a bit about my faith.

"To Learn the Surpassing Knowledge of Jesus Christ"


Reading the Bible isn't an option.

Since I'm a Catholic, can read, and have access to Sacred Scripture, it's a requirement. That's because "ignorance of the Scriptures is ignorance of Christ," and knowing our Lord is a very high priority:
"More than that, I even consider everything as a loss because of the supreme good of knowing Christ Jesus my Lord. For his sake I have accepted the loss of all things and I consider them so much rubbish, that I may gain Christ"
(Philippians 3:8)

"The Church 'forcefully and specifically exhorts all the Christian faithful. . . to learn the surpassing knowledge of Jesus Christ, by frequent reading of the divine Scriptures. Ignorance of the Scriptures is ignorance of Christ.112"
(Catechism of the Catholic Church, 133)
I really do not think accepting "the loss of all things" and considering them rubbish means that I should sell everything my wife and I have, give the proceeds to the nearest charity, and hope we survive the next winter.

Humility and Getting a Grip


For starters, my wife wouldn't like that: and I don't think impoverishing the family is consistent with my duties as a parent. (Catechism, 2221-2233, 2252)

For another, being humble before God doesn't mean being poverty-stricken.

Being poor or rich is okay. What matters is what we do with it. (Catechism, 544, 2445)

We all have equal dignity and rights, which doesn't mean we're all alike: and this is okay, too. (Catechism, 1934-1937)

Humility is accepting reality: acknowledging that God is the author of all good.1

In my case, it's acknowledging that God blessed me with defective hips, freakishly-enhanced language skills, and a probably-inherited predisposition to depression and something on the autism spectrum.

My contribution to the mix is deciding to do something with that quirky took kit. (October 18, 2015; March 29, 2015)

Getting back to whether or not Earth is flat: insisting that the Almighty must conform to a contemporary blind-to-metaphor reading of ancient poetic imagery seems pretty much the opposite of humble. (March 27, 2016; March 29, 2015)

Free Will and Death


I have free will. I can decide what I do, or don't do. (Catechism, 1730-1742)

Deciding wisely would be a lot easier if we hadn't been dealing with consequences of a really bad decision, and that's another topic. (Catechism, 388-390, 396-412)

I try to keep deciding that following our Lord is more important than anything else, even if that means putting up with the occasional inconvenience or frustration.

I don't know how I'd respond if I was in Stephen's position, after he said something that folks didn't want to hear:
"They threw him out of the city, and began to stone him. The witnesses laid down their cloaks at the feet of a young man named Saul.
"As they were stoning Stephen, he called out, 'Lord Jesus, receive my spirit.' 5"
(Acts 7:59)
Keep an eye on young Saul. A bit later, on his way to Damascus, he had an intense interview with our Lord. (Acts 22:6-11)

After that, the narrative calls him Paul. I gather his name wasn't changed. He was a Jew and a Roman citizen, so he had a name for use in both cultures.2

He may have been exaggerating in 1 Corinthians 15:31, saying "every day I face death" — but if so, it wasn't much of an exaggeration. He eventually went to Rome and lost his head: literally.3

"We are Infinitely Loved"


Why would folks like Stephen and Paul let themselves be killed, rather than stop talking about our Lord? Let's see what Paul wrote.
"And I wrote as I did 1 so that when I came I might not be pained by those in whom I should have rejoiced, confident about all of you that my joy is that of all of you."
(2 Corinthians 2:3)

"But, even if I am poured out as a libation 14 upon the sacrificial service of your faith, I rejoice and share my joy with all of you.
"In the same way you also should rejoice and share your joy with me."
(Philippians 2:17-)
Two millennia later, joy is still at the core of being Christian — or should be.
"...Joy is at the heart of Christian experience. ... In a world of sorrow and anxiety, joy is an important witness to the beauty and reliability of the Christian faith...."

"...A yearning for joy lurks within the heart of every man and woman. Far more than immediate and fleeting feelings of satisfaction, our hearts seek a perfect, full and lasting joy capable of giving 'flavour' to our existence...."
("Message for the 27th World Youth Day," Pope Benedict XVI (March 15, 2012))
It's hardly a new idea:
"Sing praise, play music; proclaim all his wondrous deeds!
"Glory in his holy name; rejoice, O hearts that seek the LORD!"
(Psalms 105:2-3)

"In contrast, the fruit of the Spirit is love, joy, peace, patience, kindness, generosity, faithfulness,
"gentleness, self-control. Against such there is no law."
(Galatians 5:22-23)
Two millennia after our Lord stopped being dead,4 joy is still important. Or, like I said, it should be. That's joy, not giddiness:
"...A joy ever new, a joy which is shared

"The great danger in today’s world, pervaded as it is by consumerism, is the desolation and anguish born of a complacent yet covetous heart, the feverish pursuit of frivolous pleasures, and a blunted conscience....

"...I invite all Christians, everywhere, at this very moment, to a renewed personal encounter with Jesus Christ, or at least an openness to letting him encounter them....

"...There are Christians whose lives seem like Lent without Easter. I realize of course that joy is not expressed the same way at all times in life, especially at moments of great difficulty. Joy adapts and changes, but it always endures, even as a flicker of light born of our personal certainty that, when everything is said and done, we are infinitely loved...."
("Evangelii Gaudium," Pope Francis (November 24, 2013))

"Whatever God Wills is Done"


I could be a Christian, following our Lord, if Earth was a flat plate and the sky a dome with water on the other side.

But it's become increasingly obvious that God's creation is not like that.

I don't mind a bit. I see scientific discoveries as invitations to "even greater admiration" of God's greatness. (Catechism, 283)

Besides, we've always known it was big and old.
"1 Think! The heavens, even the highest heavens, belong to the LORD, your God, as well as the earth and everything on it."
(Deuteronomy 10:14)

"The heavens declare the glory of God; the sky proclaims its builder's craft."
(Psalms 19:2)

"4 Indeed, before you the whole universe is as a grain from a balance, or a drop of morning dew come down upon the earth."
(Wisdom 11:22)
Being upset that it's bigger and older than we thought doesn't make sense: not to me.

Even if I did disapprove of the Almighty's creation, it wouldn't make much difference:
"Our God is in heaven; whatever God wills is done."
(Psalms 115:3)

(From NASA, ESA, and the Hubble Heritage Team (STScI/AURA); ESA/Hubble Collaboration; used w/o permission.)

More of my take on God, the universe, and getting a grip:

1 Humility, a Catholic view:
"HUMILITY: The virtue by which a Christian acknowledges that God is the author of all good. Humility avoids inordinate ambition or pride, and provides the foundation for turning to God in prayer (2559). Voluntary humility can be described as 'poverty of spirit' (2546)."
(Catechism of the Catholic Church, Glossary, H)
2 One man, two names; dual names in Roman times:
"Saul, also known as Paul: there is no reason to believe that his name was changed from Saul to Paul upon his conversion. The use of a double name, one Semitic (Saul), the other Greco-Roman (Paul), is well attested (cf ⇒ Acts 1:23 Joseph Justus; ⇒ Acts 12:12, ⇒ 25, John Mark)."
(footnote 5, Acts 13, New American Bible)
3 See:
4 As I've said before, it took a series of meetings to convince the surviving 11 that our Lord was really, no kidding, break-bread, eat-a-fish, put-your-hand-in-my-side, ALIVE. (April 5, 2015)
"And it happened that, while he was with them at table, he took bread, said the blessing, broke it, and gave it to them."
"With that their eyes were opened and they recognized him, but he vanished from their sight."
(Luke 24:30-31)

"While they were still incredulous for joy and were amazed, he asked them, 'Have you anything here to eat?'
"They gave him a piece of baked fish;
"he took it and ate it in front of them."
(Luke 24:41-43)

"Now a week later his disciples were again inside and Thomas was with them. Jesus came, although the doors were locked, and stood in their midst and said, 'Peace be with you.'
"Then he said to Thomas, 'Put your finger here and see my hands, and bring your hand and put it into my side, and do not be unbelieving, but believe.' "
(John 20:26-27)

Chameleons, Crystals: and Curiosity

Chameleons may be more famous for changing color than for their high-speed tongues: but today I'll be talking about both.
  1. Chameleon Tongues, Mathematically Described
  2. Crystals in Chameleon Skin

Brains, Curiosity, and Being Human


Using our brains is part of being human. So is learning about the universe, and using that knowledge. We're supposed to use our brains. (Catechism of the Catholic Church, 154-159, 2292-2296)

But, particularly if we act without thinking, curiosity can get us killed. I've talked about Georg Wilhelm Richmann before, and why "tickling the dragon's tail" is a bad idea.

Also why Ulysses is in Dante's Malebolge, and it's not because being curious is wrong. (January 23, 2015)

Let's see, what else?

Ethics matter.

'It's for science' isn't an excuse for subjecting humans to lethal experiments: or mistreating animals. I've talked about that before. (March 27, 2015; December 5, 2014)

Basically, science and technology are fine. Ignoring ethics isn't. (Catechism, 159, 2292-2296, 2375-2377, 2414)


1. Chameleon Tongues, Mathematically Described



(From SPL, via BBC News, used w/o permission.)
("The chameleon feeds by snapping out its long tongue"
(BBC News))
"Chameleon's tongue gives up secrets"
Helen Briggs, BBC News (April 20, 2016)

"Scientists have built a mathematical model to explain the secrets of the chameleon's extraordinary tongue.

"It took more than 20 equations to capture mathematically how the reptile's tongue unravels at very high speed to snare insects.

"The model explains the mechanics of the animal's tongue and the inherent energy build-up and rapid release.

"British researchers say the insights will be useful in biomimetics - copying from nature in engineering and design...."
Depending on who you read, chameleons have been around for 60,000,000 years, give or take, or roughly 20,000,000 years. That's how far back we've found various iguana-like fossils.

The odds are good that the critters have been around for a lot longer, and share a common ancestor with iguanids and agamids upwards of 100,000,000 years back.

Somewhere along the line, chameleons acquired their color-changing ability. They're not the only variable-color animals. Quite a few critters go through seasonal color changes, of course; but anoles, squids, octopi, and cuttlefish change quickly.

Back to chameleons: we know of 202 species, not all can change color; they've got zygodactylous feet, which is a fancy way to say two toes point backwards; and they've got weird eyes.

A chameleon eye's lens is convex, not concave like ours. That's not obvious, looking at them, but the way they move their eyes independently of each other is.

Chameleons can swivel their eyes around a whole lot more than we do, which lets them stay still while waiting for their next meal: or avoiding being another critter's food.

Tarsiers have enormous eyes for their size, at least some can turn their heads a full 180 degrees. I'm assuming that's 180 left or right.

Oxford University's professor of mathematical biology Derek Moulton clarified — if that's the right word — what these scientists did:
"...'In mathematical terms, what we've done is we've used the theory of non linear elasticity and captured the energy in these various tongue layers and then passed that potential energy to a model of kinetic energy for the tongue dynamics.'..."
(Helen Briggs, BBC News)
I gather what that means is that the scientists found a set of equations that do a pretty good job of describing what a chameleon's tongue does.

It's a very complicated organ: modified hyoid bones at the core, then about a dozen very thin layers of fibrous material, wrapped in muscles. Energy gets stored in elastic elements — which is what the scientists now understand a bit better.

Heads, Neck Injuries, Getting a Grip, and Designing Robots


We can turn our heads something like 80 degrees left or right: apparently that's about the same for men and women, on average, although men generally have more muscle in our necks.

That may help explain why men aren't quite as likely to have neck injuries. I'd better explain that, considering the preferred reality many folks insist on.

I think humans came in two basic models, male and female: and that this is okay. (May 2, 2012)

That is not even close to yearning for the 'good old days.' I've discussed Addams Family Values, love, and moving forward, before. (January 31, 2016; August 30, 2015; July 12, 2015)

I must believe that we're all created in the image and likeness of God: with free will, masters of our own actions. I must also see all of us as people, with equal dignity: no matter where we are, who we are, or how we act. (Genesis 1:27; Catechism, 360, 1700-1706, 1730-1825, 1932-1933, 1935)

But I don't have to insist that I'm indistinguishable from Elizabeth II, John Krahn, Akihito, or Phumzile Mlambo-Ngcuka. I look a bit like the first two, though: largely because my recent ancestors spent a long time in northwestern Europe.

Less hair and more beard, though, and that's another topic. Topics.

Where was I? Chameleons, eyes, being human. Right.

We've known that chameleons could shoot out their tongues fast and far — and have been learning more about how they manage it. This research could help scientists and technicians design soft, elastic materials for robotics. That's not the scientists' main motive, though. They said their reason for researching was mostly just "scientific curiosity."

More than you probably need (or want) to know about chameleons, tarsiers, and humans:

2. Crystals in Chameleon Skin



(From Alex Hyde/SPL, via BBC News, used w/o permission.)
("The study was conducted on panther chameleons, which are popular pets"
(BBC News))
"Chameleon colours 'switched by crystals' "
Jonathan Webb, BBC News (March 11, 2016)

"Swiss researchers have discovered how chameleons accomplish their vivid colour changes: they rearrange the crystals inside specialised skin cells.

"It was previously suggested that the reptiles' famous ability came from gathering or dispersing coloured pigments inside different cells.

"But the new results put it down to a 'selective mirror' made of crystals.

"They also reveal a second layer of the cells that reflect near-infrared light and might help the animals keep cool...."
Like I said before, (some) chameleons can change color. The real animals are nowhere near as versatile as their cartoon counterparts, though.

Researchers are pretty sure chameleons change color for different reasons: blending in with their surroundings, staying warm or cool, or signalling each other.

Iridophores



(From Teyssier, Saenko, Van Der Marel, Milinkovitch, via BBC News, used w/o permission.)
("A panther chameleon can switch in minutes from camouflage colours to more strident, communicative ones"
(BBC News))
"...Some changes arise from shifting pigments. Tiny packets of the dark dye melanin, for example, can be spread throughout the tendrils of big "melanophore" cells - or gathered into the centre, to lighten the skin again. Many fish and reptiles grow lighter or darker in this way in response to stress, or to match their surroundings.

"Panther chameleons, the subjects of the new study, do this as well. But males can also change between entirely different colours, turning a camouflaged green into a more spectacular yellow, for example, when they see a potential mate or a competitor.

"Until now, many scientists had thought that these changes arose from a similar dispersion trick with yellow or red pigment. The new research suggests this is not the case...."
(Jonathan Webb, BBC News)
Color-changing chameleon skin has a layer of guanine crystals under the outer pigments. The crystals reflect different wavelengths, depending on how they're spaced and arranged: which changes the critters' colors.

Guanine is one of the four main nucleobase in DNA and RNA. We use crystalline guanine as a shampoo additive — for an iridescent look — metallic paints, eye shadow, and nail polish.

The stuff has two tautomeric forms, keto and enol: which matters to folks who make a career or hobby of organic chemistry. My guess is that you're more likely to hear someone mention iambic pentameter: which has more to do with Shakespeare than meters, and that's yet another topic.

Those guanine crystals are in iridophores, a special sort of pigment cell. Here's a photo:


(From M. Milininkovitch, via BBC News, used w/o permission.)
("Inside the 'iridophore' cells of a relaxed chameleon (left) the crystals are tightly packed; excitement causes them to loosen (right)"
(BBC News))

Cool Chameleons



(From M. Milinkovitch, Lanevol.org, via BBC News, used w/o permission.)
("An extra layer of cells that reflect near-infrared wavelengths may help chameleons stay cool in the sun"
(BBC News))
"...Beneath the layer of iridophores that contained a nice, regular lattice of crystals, the team also spotted an additional layer, where the cells were much bigger and more chaotically organised.

"Because that higgledy-piggledy structure reflects near-infrared light particularly well, they believe it might serve to reflect the sun's warming rays and keep the chameleons cool.

"This split appears to be unique to chameleons; other lizards tend to have their crystals arranged in a regular way to give bright colours, or a disorganised way that reflects the heat. With their added layer, chameleons manage to combine the two extremes...."
(Jonathan Webb, BBC News)
Merriam-Webster says "higgledy-piggledy" first showed up in 1598, means "in a confused, disordered, or random manner," and that we don't know its etymology.

Etymology is a word's derivation, entomology is the scientific study of insects, and chameleons eat insect. Insects have compound eyes, some critters with compound eyes living near hydrothermal vents can see infrared.

Quite a few insects can see ultraviolet colors. So could we, at least the wavelengths close to 'visible' light, but the lens of our eye is opaque to ultraviolet. And that's — you guessed it — still another topic.

What's That Doing in a Nice Catholic Blog?

From time to time, a service that I use will display links to - odd - services and retailers.

I block a few of the more obvious dubious advertisers.

For example: psychic anything, numerology, mediums, and related practices are on the no-no list for Catholics. It has to do with the Church's stand on divination. I try to block those ads.

Sometime regrettable advertisements get through, anyway.

Bottom line? What that service displays reflects the local culture's norms, - not Catholic teaching.
