Do our aging cells necessitate that we age overall as people? Flipping it around, if we can stop or reverse enough cellular aging, will our overall aging be positively affected? It’s clear that people age very differently from each other and so do our cells and organs. Interestingly, intramurally in a sense the cells and […]

Have you had the chance to play around on ChatGPT, the open AI? It can “talk” to you in text kind of like a person. I have tried it out. It’s quite interesting to type in scientific questions and see what pops out. Often it is high-quality text and solid ideas, but not always. You

Let’s start with a couple of new pieces on in vivo reprogramming. The idea here is to do something like making iPS cells but doing it inside organisms and not quite pushing cells all the way back to pluripotency. Just younger, healthier cells. Why do that? The goal is to achieve a kind of anti-aging

What is a stem cell therapy? Does it have to include stem cells put into the body? Would you include a therapy that uses differentiated cells made from stem cells? I generally do use the term in that broader way. A similar question comes to mind: what is regenerative medicine? Should it include both cell

I’ve been wondering how the new Google AI overviews feature on its search platform would turn out for various stem cell searches. Frankly, I had a bad feeling that Google was going to blow this. Unfortunately, it seems even worse than I anticipated. Let’s go through three examples and talk about why this is so

There has been a big jump in paper retractions in science over the last 20 years. What’s going on? How do the trends in the stem cell field compare to other fields like cancer research and more broadly? Is AI going to change the dynamic between those engaging in misconduct and those who are looking for misconduct

Someday could human brain organoids get to the point of having organized human-like thoughts? Even consciousness? The more time passes, the less likely I think this is. It’s not impossible, but brain organoids have big limitations in that regard. To be clear, I don’t mean brain organoids having some vaguely human brain-like electrical activity. Even monolayers of

What is a stem cell niche? It’s the home of stem cells. The stem cell niche is a fascinating environment. It has many constituents that impact stem cell behavior and even eventual stem cell transplant functions. In today’s weekly reads, we’ll start with the niche as there have been several interesting papers on this topic. The

Near-billionaire Bryan Johnson apparently does not like getting old and he’s trying to do something transformative about it. He and his team are experimenting in a big way. As a 55-year-old myself, I can’t blame him for wanting to fight aging in general. However, his anti-aging project includes some extreme stuff. Will some in the
