If we can kill off the senescent cells in our body, we will grow younger. This paper by Poblacka and associates describes a way to accomplish that… in cells in a dish. But it’s an important step and I’ll explain why. I want to go through a peer-reviewed paper I found really interesting. It’s about a new technique to kill senescent cells and it’s a step toward managing, slowing, or even stopping the aging process.

This post also appears on my youtube channel for long-form essays. Here’s the link.
Today, we’re diving into the world of longevity research – examining the supplements Nicotinamide Riboside (NR) and Nicotinamide Mononucleotide (NMN).

The big question is: are these pills worth the money – will they buy a human a few extra youthful years – or is it just an unregulated supplement cash grab?

You can check out the whole video on the topic over at PeterAllenWrites (link). I do have concerns about the ethics of AI-generated content, but I can also see the value of AI art for science communication. As an example, I made this comic about the scientific method, as performed in real life.
