Today we got the first report of a baby being born via so-called “3-person IVF”, sometimes called 3-parent IVF, in which the DNA of three people contribute to an offspring. Before discussing this further I have to emphasize that we need proof that this is indeed really a 3-person IVF baby via genetic testing. Until that data is released publicly we should all be cautious on this news. Apparently the clinic plans to present such data later. Assuming it is a 3-person IVF baby, which …Read More

Was an intensely hyped Nature paper connected to the subsequent knighthood for one of the authors just two days after publication? It’s hard to imagine there isn’t a connection and such a link is bad news for biomedical science. Professor Doug Turnbull and fellow UK authors published a Nature paper a few days ago that reinforced a safety concern about 3-person IVF/mitochondrial replacement. The same safety issue had also been raised by an earlier paper by a different team. However, some of the authors of the new …Read More

Today a new Nature paper from Dr. Mary Herbert’s group in the UK has found a key problem with mitochondrial replacement therapy that fits with data from others. The goal of preventing mitochondrial disease using various kinds of genome transfer technologies is a noble one, but mitochondrial replacement therapy has faced a number of technological challenges including perhaps most prominently the carryover and subsequent amplification of diseased mitochondria. This mitochondrial replacement carryover issue was clearly defined in an excellent recent Cell Stem Cell paper …Read More

Some stuff on my mind for our TGIF Science this week. Research Funding Ups: NIH. Is it my imagination or is NIH funding slightly improving? This is the overall vibe I’m hearing from the trenches. Research Funding Ups and Downs: CIRM.  CIRM funded some basic research to the tune of a total of $4 million, which is great. On a personal level, just wish my “great idea” had fared better in review there. Kind of a downer, but after a while you get a …Read More
