Most of us have heard of organoids but what about the related model called an “assembloid”, which is a term growing in use including from organoid researcher Sergiu Pasca of Stanford? Before we jump into that, be sure to enter The Niche stem cell image contest for your chance to win $100 or some swag. […]
Retraction Watch has been a great resource for those of us who have been following research misconduct. They widely cover and conduct research on retractions, corrections, and other developments in this space. Unfortunately, there’s been plenty to write about even just within the stem cell and cell therapy arena, which is my primary interest. Think
I wrote earlier this week about genome sequencing of famous dead celebrities, pointing out that the trend seems full of ethical complexities. Genome news More broadly, sequencing the genomes of non-celebrities from hundreds or thousands of years ago can be important research. A new NYT piece covers such work on the Swahili people. Such research

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

Occasionally when I write a post there is an angry reaction to it in the blog comments, which was the case for my recent fact-check of the LifeWave X39 patches. As you can see in that post, I didn’t find convincing data to either back up the claimed stem cell connection. In my opinion, there

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

It’s always exciting when your lab has a new paper and my team just published a study knocking out the H3f3a gene in mice, which codes for histone H3.3 protein. We found that loss of this gene leads to lethality at a late stage of embryonic development. There were also indications of more specific phenotypes

Toward the end of each year, I make stem cell & regenerative medicine predictions for the coming year. It’s a fun tradition here on The Niche that goes way back. The stem cell field has changed dramatically as reflected in each year’s predictions. Here’s a list of past predictions with my grades of how they

Today’s post is on the lighter side with some humor on funny autocorrect fails related to science. It’s surprising sometimes how far certain tools can lag behind cutting-edge science. Spellcheck tools are useful, of course, but they don’t always know what to do with STEM words. The same is true of tools like Grammarly, although it

When you are a stem cell biologist and especially if you do a blog, you sometimes run across very strange things like a chimera cat. In this case, I stumbled on the whole topic of chimeric cats because I was searching for info on chimeric rats on Google. Of course, I was. It’s kind of
