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 […]

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

Near-billionaire Bryan Johnson apparently does not like getting old and he’s trying to do something transformative about it. He and his team are experimenting in a big way. As a 55-year-old myself, I can’t blame him for wanting to fight aging in general. However, his anti-aging project includes some extreme stuff. Will some in the

About ten years ago I ran across the organism called the immortal jellyfish. Luckily I didn’t get stung because it wasn’t an in-person encounter like while swimming. Rather, I came upon the idea that these guys lived forever. Someone was even selling an immortal jellyfish extract. They claimed it would reverse aging in people. That

It’s always exciting when your lab has a new paper and my team just published a study knocking out the H3f3a gene in mice, which codes for histone H3.3 protein. We found that loss of this gene leads to lethality at a late stage of embryonic development. There were also indications of more specific phenotypes

Let’s start with a couple of new pieces on in vivo reprogramming. The idea here is to do something like making iPS cells but doing it inside organisms and not quite pushing cells all the way back to pluripotency. Just younger, healthier cells. Why do that? The goal is to achieve a kind of anti-aging

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

I tend to perhaps over-focus on human CRISPR or gene editing, but other applications including in agriculture are definitely going to be huge. CRISPR in agriculture One that I’ve been following for a long time is the use of CRISPR to prevent cows from growing horns. Why is that a big deal? Just in the

Many celebs seem to be into cosmetics called Augustinus Bader cream products that claim to do something related to stem cells. The brand is wildly expensive. What’s this all about? Augustinus Bader is both a person and a line of cosmetic products. The goal of today’s post is to fact-check the claims and products of the Augustinus

I started The Screamers a few years back as a biomedical science hype award. It’s kind of in the spirit of an Ig Noble Prize in the sense of an alternative “award”, but in this case for hype. In 2020, sadly the FDA Commissioner at the time Stephen Hahn won The Screamers award for a
