What We Can Learn from a Dead Walking Cat with No Brain

It’s Halloween time, which is a big deal in my house. My wife loves to decorate heavily, and we all get into it as we live in a neighborhood that gets hundreds of kids an hour. At a recent conference, I saw this great video of an old dead-cat experiment, and I thought it was…read more

Circulus in Demonstrando: The PNE Pain Deniers and Some Recent “Research”

There’s nothing like a good circular argument, what our esteemed Latin ancestors called circulus in demonstrando. You would think that scientific papers that focus on theories of why patients are disabled must be well grounded in objective measurement.

This…read more

Does Age Affect Stem Cell Treatment Success?

Does your age impact stem cell treatment success? We’ve looked long and hard through the years for this association, but it’s been, for the most part, elusive. We’ve published a number of scientific papers on the topic, but now a group of chiropractors is fabricating from thin air a narrative about age and stem cells.…read more

How to Determine Cell Viability and Vitality

Many physicians and patients get pitched on amniotic and cord “stem cell” products based on a document that purports to show that these cells are “viable”. However, there’s much more to the story than a simple viability percentage. You need to know a lot more to determine if cells are vital and healthy. What Is…read more

Surgery to Remove Cartilage in the Knee: Not Effective!

Surgery to remove cartilage in the knee likely happens thousands of time each day.
