Superhumans



“You reached for the secret too soon, you cried for the moon.”

I know it is not what Pink Floyd was saying with this lyric from “Shine On you Crazy Diamond”, but something about it makes me think of the Apollo One disaster. America was trying to win the space race and perhaps pushed too hard and tried to do too much too soon, which resulted in three astronauts dead in their capsule. It reminded me that sometimes we push the boundaries of science too hard.

It is apparently human nature to try to do something as soon as we are able. History is full of examples of someone doing something just because they can, before considering all the ramifications. The most recent example is the Chinese scientist who claims to have created the first genetically edited baby by using Crispr. We don’t know if he actually did it or not, that is yet to be proven. Even if he didn’t, it is probably only a matter of time until someone does. The problem is, we are nowhere near understanding all of the consequences of human gene editing. There are people who have died after undergoing attempts at gene therapy. One woman died the day after getting injected with genetically engineered viruses to treat her rheumatoid arthritis. These attempts at gene therapy were done under strict conditions with very limited scope but still the doctors could not predict the outcome. Clearly we weren’t ready.

This is why it takes the FDA years to approve new drugs or medical procedures. Scientists understand that it takes time to understand all the consequences (if they ever can). They understand that because there have been so many mistakes in the past. Thalidomide seemed like a good idea at the time to treat morning sickness in pregnant women. Nobody thought to check if it might cause birth defects.
How does one system in the human body interact with the myriad of other systems? The interdependencies are so complex that it verges on chaos theory. That is not to say that we will never understand what happens when you introduce a new gene or chemical or other stimulus to a human body, just that it might take a very long time to fully understand it.

Hollywood is going through a phase of superhero movies. I like superheroes as much as the next person as long as we recognize it as fantasy. Many of the origin stories for superheroes involve a mutation (X-men, Spiderman, Fantastic Four, etc.). If a human gets exposed to high level of radiation, will it cause a mutation that will turn them into Spiderman? I suppose it is possible (in the same way that if an infinite number of monkeys had an infinite number of typewriters, one of them might bang out the manuscript for Hamlet), but it is far more likely (almost a certainty) that they will die a terrible death. Random mutations to individual cells happen all the time in our bodies. Usually it just produces a cell that can’t survive, and that is the end of that mutation. Sometimes it produces cancer. Very rarely it produces a cell that was better at something than the original cell it came from. This is the driving force of evolution. This is why evolution takes so long. It mostly produces dead ends.

Trying to genetically engineer the human genome is trying to take short cuts in evolution. This is unquestioningly a bad idea until we know everything there is to know about it, which is decades, if not centuries away. Until then the best advice would be: don’t mess with Mother Nature.

Iron Fist in a Velvet Glove

  Despite both of us having science backgrounds, my wife and I share a leaning toward the artistic, though we may express it in different ways. In her life, my wife has been a painter, a poet, a singer, an actor, and a fiction writer. Not to mention a mother. I don’t remember what precipitated this event, but my wife, my son, and I were at home in the front room. My wife was responding to something my son said. She said, “remember, you get half your brains from me. If it wasn’t for me, you’d be a complete idiot.” To which my son started howling with laughter and said to me,” I think you have just been insulted.” Sometimes I feel like Rodney Dangerfield. I get no respect. But that is not an uncommon state of affairs for fatherhood. When my son was going to middle school and high school, my wife was always the one to go in with him to get him registered for classes. One time she was unable to go and I had to be the one to get him registered. “Ugh,” he said. “why can’t Mama do i...

Empathy

  Websters defines Empathy as: “the action of understanding, being aware of, being sensitive to, and vicariously experiencing the feelings, thoughts, and experience of another.” Empathy is what makes us human, though lord knows there are many humans who don’t seem to have any. A person without empathy is like a caveman, only concerned for himself. Selfish. It is a lack of community and by extension, a lack of the need for civilization. The person who lacks empathy can have a bit of community, but only with others exactly like himself. It seems like societies go through cycles of empathy and less empathy. Sometimes a single event can change the course of society. Prior to America’s involvement in WWII, the general feeling in America was not very empathetic. We had our own problems. We were still dealing with the lingering effects of the Great Depression, and had been for years. That kind of stress makes it hard to think of others. Hitler was slashing through Europe. He and his fol...

A Deception

  I have a secret. I deceived my mother. Okay, it was like 50 years ago and she is gone now, but still . . .  I was generally a good boy. I did as I was told. My family lived a pretty strait-laced, middle-class, fairly conservative life. We were a G-rated family, well, until my older siblings broke the mold, but at this time, I was still in the mold. My friend Rich and I made a plan. Rich had asked me if I wanted to see Cabaret . He said he didn’t think much of Liza Minnelli, but he wouldn’t mind seeing her take her clothes off. We were like 13 years old and sex was ever-present on our minds as much as it was absent in our households. Cabaret was not rated R. It was rated PG. The ratings system has changed since that time. There was no PG-13; there was just the choice of G, PG, and R  (X was not an official rating).  Apparently the makers of Cabaret satisfied the ratings commission enough to escape an R rating, so it was PG.   There was therefore no law or ...
