First Attempt to Replace a Blogger with AI.

The old computer joke for newbies is, "I could replace you with a short bash script". Maybe it's now true?

Can writers be replaced by AI? Can I?

This is my first attempt to replace my blogging with AI. I asked an AI how to do it. After asking an AI, how to build a good prompt, to get it to create a science blog, it came up with a template like this, where you fill in the subject and a URL, and use that as a prompt. Here is an example below. (It is obviously AI generated. Note the typical AI marks like the — symbol, that humans rarely use.)

I think my earlier articles on this subject are better than this, but I think it did a creditable job. No real mistakes. What do you think?

Write as a science writer, an optimistic 4-paragraph science blog for a public audience that is interested in science,

Rewriting the Biological Clock: How “Longevity Genes” Can Recharge Our Stem Cells

Imagine a reset button for your body’s internal repair system—that’s the thrilling promise emerging from the frontier of genetic medicine. At the core of our body’s ability to heal and regenerate are stem cells, but just like the rest of us, they slow down and wear out with age, leading to the gradual decay we call aging. Now, a groundbreaking study featured in Cell Death & Disease shows scientists have successfully hacked one of the most famous human “longevity genes,” called FOXO3, to turn these aging stem cells into powerful engines of rejuvenation. This is not about simply slowing decline; it’s about deploying genetically engineered cells to fight aging from the inside out, offering a tantalizing glimpse into a future where age-related frailty is a condition we can manage.

The breakthrough involves transforming human mesenchymal progenitor cells (MPCs)—a type of stem cell responsible for maintaining many tissues—into Senescence-Resistant Cells (SRCs). The key was permanently activating the FOXO3 gene within them. Think of FOXO3 as a cellular master switch that promotes DNA repair, stress resistance, and cell survival. Armed with this switch, the SRCs were tested in a 44-week trial on aged non-human primates, yielding results that can only be described as systemic rejuvenation. The treatment didn’t just prevent further decline; it actively rolled back age-related damage, leading to sharper cognitive function, a noticeable strengthening of bone density, and even restored reproductive vitality.

The way these supercharged cells work is perhaps the most exciting part. The SRCs act as tiny pharmacies, dispatching microscopic lipid packages called exosomes throughout the body. These exosomes are loaded with a cocktail of anti-inflammatory molecules, longevity proteins, and genetic instructions. Once released, they seek out and neutralize cellular senescence—the state where old, dysfunctional cells pollute the surrounding tissue with toxic, pro-aging signals. By clearing out this ‘cellular garbage’ and dampening chronic inflammation—a primary driver of virtually all age-related disease—the FOXO3-engineered cells orchestrate a widespread, restorative effect across multiple organ systems. This represents a highly sophisticated, cell-based medicine approach to tissue repair and vitality.

This precise gene-editing strategy provides a powerful blueprint for future interventions that could redefine the human lifespan. The approach can be easily leveraged to target other known “Hallmarks of Aging,” such as stabilizing telomere length or reversing detrimental epigenetic drift (the changes in gene expression that accumulate with time). For instance, other experiments could activate genes known to boost mitochondrial function or enhance protein quality control, and then use the same delivery method to distribute those rejuvenated cells—or their exosomes—systemically. What we are witnessing is the potential shift from treating the symptoms of aging—like heart disease or Alzheimer’s—to treating aging itself, promising not just a longer life, but a far healthier one.
