Gene Editing - The Parental Angle

James Metzl’s book, Hacking Darwin, is about genetic editing and the future it is likely to yield. How are things likely to play out as these technologies become more commonplace, affordable and accessible? Yes, there’s the risk of those Frankenstein’s Monsters, but there are other aspects too.

 

But first, he pokes holes in the “It’s not natural” argument against gene editing:

“We have deep seated ideas of what’s natural, but much of it isn’t natural at all… We have been in the business of altering the biological and other systems around us for so long.”

How is agriculture natural, he asks. Do crops grow like this left to themselves? And over thousands of years, hasn’t our choice of which plants and crops to grow led to selective breeding of varieties and traits that suit us?

 

Consider those fatal diseases that kill early that are based on a single gene:

“If you could prevent your child from having the disease in the first place (by genetic editing), would you do that?”

This is an instance where most people do support genetic editing.

 

Now consider a scenario where no genes are edited. But multiple embryos are conceived in a lab using the un-edited eggs and sperms of parents. No editing in this scenario but you get to decide which embryo becomes your baby after all the embryos’ genes have been analyzed. That analysis tells you “statistical probabilities” of certain diseases, certain characteristics. Yes, it’s all probabilities, nothing for sure. But if studies say “tall people have higher income”, even though you don’t think that’s fair, wouldn’t it better to have a taller child, for your child’s prospects? Or take the case of IQ:

“You know IQ doesn’t measure everything… But are you prepared to reject the concept of IQ out of hand and leave it to your future child to suffer the consequences if you are wrong?”

You know the answer, and it will often be based on the fact that:

“Other parents are making those same decisions.”

 

Which is why journalist Jon Entine wrote:

“Modern eugenic aspirations are not about the draconian top-down measures promoted by the Nazis and their ilk. Instead of being driven by a desire to “improve” the species, new eugenics is driven by our personal desire to be as healthy, intelligent and fit as possible – and for the opportunity of our children to do so as well.”

 

I feel it’s pretty clear which way parents will head on this topic… world-over.

Student of the Year

As a toddler, my daughter loved Alia Bhatt’s songs, esp. the ones from Student of the Year . (That movie did have many good songs and well-choreographed dances). Fast forward to present day, when she is 12 yo. She rarely watches Hindi movies now, but one of the few ones she likes of late, Raja aur Rani ki Prem Kahani has, yes, Alia Bhatt.   If I had any hopes that there was anything to be read in the name of her toddler-time favorite ( Student of the Year ), they have been dashed. Our conversations come exam time are perfectly captured by this photo and its caption: In fact, the pic below captures how she and I look at her answer sheets – me intently, she with an expression of “It’s over, so why are you even looking at it?”   Of late, we pull her leg and tell her that she isn’t showing any signs of academic prowess, she’d better find a rich guy to marry. Some time later, she showed us this meme on the Internet: “Me No Study, Me No Care Me Go Marry Millionaire If He Die

Animal Senses #7: Touch and Remote Touch

Instinctively, we think touch is based on contact. Not entirely true, explains Ed Yong in Immense World – there’s a more important aspect than contact: “These incredible feats are possible through movement. If you rest a fingertip upon a surface, you can get only a limited idea of its features. But as soon you’re allowed to move, everything changes. Hardness becomes apparent with a press. Textures resolve at a stroke.” As you run your fingers over a surface, they hit the tiny peaks and troughs and set off vibrations in the mechanoreceptors at their tips.   At the tip of its snout, the star-nosed mole has many pairs of hairless appendages. It uses them to touch things around itself. Alive or dead? Food or ignore? It does these movements at an insane speed. In the time it takes to blink our eyes, the star-nosed mole can probe, identify and swallow its food. “Light may be the fastest thing in the universe, but light sensors have their limits, and the star-nosed mole’s sense of

The Retort of the "Luxury Person"

Image
Coming up with biting and witty retorts. It’s something we dream of, but rarely manage to pull off. Worse, the more we stew over the offending remark, the more likely we are to come up with that dream retort, as Calvin ruefully points out: During our last holiday at the Taj Resort, seeing my wife carrying towels to our poolside chairs, one of the kids there mistook her for a member of the staff and asked for a towel. When my wife narrated this to us, I did not imagine that my 8 yo daughter would come up with her own retort. But a day later, my daughter recapped the incident, an incident that didn’t even involve her in the first place , and said, “You know what I’d have told that kid who asked for the towel?”. And without waiting for an answer, she told us anyway: “I don’t work here. I too am a luxury person who is living at this resort. Go get your own towel.” We were highly amused by the phrase she had coined: “luxury person”. It certainly captures the kind of holid
