Should there be a religious or moral litmus test for the NIH Director? A few dozen super conservative Republican members of Congress have written a letter to President Trump saying he should fire NIH Director Francis Collins. Why? Because they claim that Collins is not conservative enough for their taste and in particular they don’t like his support of embryonic stem cell research funding. You can read the actual letter here and see text in a clip from it below where religion is invoked. Does …Read More

It’s fun and useful for me to learn about the readers of this blog in terms of who they are and what their interests are in terms of the types of posts that I do. Below are the results of two recent reader surveys that I did to get this kind of information. The two polls got 162 and 192 responses, respectively. Before I get to discussing the results, I also included a prize/raffle element to this survey whereby I would choose one winner …Read More

Cut, modify, paste… It’s kind of a CRISPR mantra for those of us using gene editing in the lab. But it’s supposed to be happening just on DNA, right? Now it appears that someone on a team of human embryo CRISPR researchers possibly got carried away with the cutting-modifying-pasting mindset to take it beyond DNA to also do so with passages of another researcher’s published work that they apparently slightly modified and put into their own paper without any acknowledgement. The 2016 article in question containing plagiarized …Read More

I’ve been working on an outreach program I call the Knoepfler Lab Stem Cell Outreach Program for Education (SCOPE). The idea behind SCOPE is to make available on the Internet a basic page of facts about stem cells in as many languages as possible. Our motto could be articulated as “Stem cells not lost in translation!” Stem cells are a topic that concerns the people of the world, not just certain countries or certain people speaking only in certain languages. SCOPE has been a big …Read More

The Texas Legislature is considering three risky bills that would give free rein to stem cell clinics to profit big time off of patients by selling unproven and unapproved “stem cell treatments” that have little if any science behind them. I call one of these bills “Right to Profit” for clinics, which if these became law could get millions from vulnerable patients and potentially block patient rights. Some of these bills including HB 810 reportedly got a boost from emotional, teary-eyed testimony from Texas Representative Drew Springer …Read More
