Genome editing with #CRISPR is the most important life science breakthrough of our time. It's a B.C. and A.C. We interviewed @WalterIsaacson about his new book, THE CODE BREAKER, which is a masterpiece medscape.com/viewarticle/95…
w/ transcript /1
We started the conversation reading 2 key passages that convey the significance of #CRISPR /2
And this one /3
The book is not just about @doudna_lab and other protagonists, such as @zhangf @geochurch @EricLander46, Emmanuelle Charpentier, but thru the perspective of grad students and post docs and about team science /4
There is substantial emphasis on the power of basic science, curiosity and creativity, and not just the linear model of discovery.
"They were doing it purely out of curiosity, like Leonardo da Vinci" /5
The links to the computer, digital, coding parallel advances are striking. Everything from the Homebrew Computer Club, the Asilomar conferences (there has been one for #AI), patent fights over chips, 0|1 vs ACGT, and so much more /6
Isaacson does a wonderful job differentiating germline editing, such as the reckless #CRISPR Babies work by Jiankui, to the remarkable progress in somatic editing
@davidrliu @skathire /7
For me, the most heartwarming part of the book was he how brought Doudna and Charpentier back together again.
The infamous @Zoom get together /8
I asked Walter about the importance of scientists playing a role in public policy, since that certainly was not Jennifer Doudna's background. His response is remarkably insightful (not shown here) /9
On the democratization of #CRISPR, Isaacson takes a bit of a contrarian view (from the life science community) in supporting the DIY work of @4LOVofScience /10
Both @cuttingforstone and I were so deeply impressed with how lucid he made such a complex topic & into a veritable page turner. I can't recommend it enough fo anyone wanting to learn more about this breakthrough— it will have transformative impact in medicine and science

We've learned a lot more about the principal drivers of age-related diseases in the past few weeks. And that leads to a unified model to pull it all together. (open-access) Image
I review 4 new reports, summarized here:
1. The proteins from senescent cells predict age-related clinical outcomes
2. A new epigenetic age clock connects the dots between aging, the immune system, inflammation and lifestyle factors
3. People with a fast pace of aging had an increased risk of cognitive impairment, age-related diseases, disability, and mortality
4. The Importance of “Immune Resilience” for Healthspan
And present a unified I/I model for what we now know Image

Most people haven’t heard of this test, which is available in the US. It accurately predicts Alzheimer’s (not just if there’s a risk, but when). It is favorably affected by exercise and likely many other lifestyle factors.
Here’s (almost) everything we know about it. In Ground Truths (link in my profile d/t X-suppression)Image
Here's the response to exercise Image
The most sensitive and accurate biomarker to date Image

A major @Nature paper this week found a significant decline in dementia after an outdated Shingles vaccine.
I've reviewed the study and many other relevant ones in a new Ground Truths (link in profile) Image

The effect in the 2 natural experiments differed substantially by sex with the benefit predominant in women Image

Of >105,000 participants with 30-year follow-up, only 9.3% achieved healthy aging (age 70, w/o any chronic diseases). Their diet was significantly associated with this outcome🧵 @NatureMedicine Image
These are the specific foods that were linked with healthy aging and other outcomes. Green-favorable; Red-unfavorable Image
Adherence to these diets (most to least in quintiles) linked to healthy aging Image
