Stem cell research ethics topics: organoid consciousness & embryo models

brain organoids sm

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

He Jiankui

I’m sure many of you remember He Jiankui, the guy who made CRISPR babies. He ended up serving three years in jail in China. He seems to be trying for something of a comeback since his release. Were He Jiankui invitations a mistake? Some prestigious places have even invited him to give talks, which seemed

LifeWave X39 stem cell patch story has holes

LifeWave X39 patches

I often learn about new supposedly stem cell-related products like the LifeWave X39 Patch from readers. Sometimes such products are used by tens of thousands of people, in my view potentially raising risks to the public. If nothing else, people might be spending their money on something that isn’t worth it. As a stem cell biologist,

About twenty years ago a science story made big news of a so-called anti-aging Methuselah gene. Methuselah gene and anti-aging The claim was that this DNA conferred long life on people. Hence the name Methuselah, which refers to a man from the Bible who reportedly lived 969 years. The so-called Methuselah gene was at first not a

I don’t think de-extinction of animals just for the heck of it like woolly mammoths is a good idea, but what about de-extincting animals like the Dodo? Where humans caused them to disappear? If that’s even possible, is it a good idea? Dodo de-extinction A company is giving it a try. I can see the

Desperately seeking stem cells: celeb quests for elixirs often mislead

lady gaga, stem cells

What could go wrong with celebrities desperately hunting for stem cells as a fountain of youth? A flaskful of problems. Some famous folks can’t seem to get enough of stem cells, even if those supposed therapies are unproven and risky. In recent years, dozens of celebs have gotten stem cell procedures of various kinds. The

3rd Invitrx warning highlights FDA oversight weakness

The FDA seems oddly slow in oversight of unproven stem cell clinic-related firms like one here in California called Invitrx Therapeutics. I’ve written before about Invitrx, but interactions between them and the FDA have continued including a new warning letter. It’s become a puzzling situation. More broadly, the FDA has done relatively little in the past
