All science, whether biology or physics, whether microscopic or at the solar system level, is about experiments. Sometimes we as a society forget that. In fact, experiments are at the heart of investigations as diverse as studying cells to exploring space to medical treatments. For NASA, the last week has been a tale of two […]

For a few years, biophysicist He Jiankui might have been one of the most recognizable scientists on the planet. He made three “CRISPR babies” or gene edited people. However, his gene editing went badly and as best as we can tell his efforts did not result in precision edits. It’s unclear if he had institutional
Who decides what to name something new in science like “human embryo models”? Also, not to get too philosophical right off the bat, but what is the point of a name? It’s about a shared understanding of what we’re talking about. But, very often, both out in the world and in the various fields of
Beyond naming: embryo models and the importance of public dialogue Read More »
This year already appears to be a record one for cell and tissue therapy-related warning letters the FDA. Directly or indirectly, these come from the FDA’s Center for Biologics Evaluation and Research or CBER. Something unusual seems to be happening. FDA’s CBER has been exceptionally active in 2024 including on cell & tissue products I’ve

What do you think of when I mention Stanford professor Mike Snyder and self-help guru Tony Robbins together? I would not necessarily have imagined them forming a connection but science is full of surprises. I’ve admired Snyder’s work in genetics for a long time. I’m most familiar these days with Robbins for his interest in
The FDA alerted the public about issues related to amniotic eye drops last year and now the agency just warned the manufacturer of one such product called Regener-Eyes. The manufacturer is Regenerative Processing Plant, LLC. The warning letter was addressed to its owner, Carl R. Harrell, MD. What’s the deal with this warning? Let’s start
Regener-Eyes maker gets FDA warning on amniotic eye drops Read More »
If only humans could master regeneration. It seems like that would open the door to far better health. Maybe to longer life too. We can see how many other creatures innately can regenerate organs. I can see it in the lizards that run around in my garden. Every now and then I see one with
Nevada has a relatively new 2023 law legalizing non-FDA-approved biological and gene therapies. I use the word “therapies” here loosely. They are not scientifically or medically proven to work or be safe so they could lead to substantial harm. This is yet another early step in a likely growing trend of states challenging FDA authority
Mesenchymal stromal/stem cells or MSCs are widely used by unproven clinics, but MSC research also suggests real promise in specific areas. Clinics mainly use adipose MSCs (often called SVF) or bone marrow MSCs. However, umbilical cord MSC preparations are getting more popular too. Many questions swirl around the use of MSCs including what exactly are
What if we could make robots that possess human brain-like structures? Chinese scientists have reportedly made such robots that are each guided at least in part by a small amount of lab-grown brain tissue. These cyborg-like creations, which are being trained to perform specific tasks, also have standard computer chips. How much does the human
