I was at another AI roundtable today arguing intelligence is not the key bottleneck in many policy issues and so AI may not have as big an effect as some expect. So it was nice to read this from @ruxandrabio.bsky.social making the same point about medicine www.writingruxandrabio.com/p/intelligen...

In certain tech circles, it has become low-status to suggest that AGI won't automatically solve everything. I think models will continue to get smarter, but intelligence is often not the main bottleneck to physical world change. More 👇 www.writingruxandrabio.com/p/intelligen...

It's a myth that egg freezing doesn't work. It works extremely well for women who freeze young. It has low success rates for women in their 40s and late 30s, when fertility has already declined significantly. Read all about egg freezing below: worksinprogress.co/issue/were-f...

We're freezing our eggs; maybe you should too

You have been told that egg freezing doesn't work. Not true. Its effectiveness is limited only by a woman's fertility when they freeze.

China is winning the drug discovery race. There's no better example of this than multiple myeloma. For decades, patients endured cycles of brutal treatment. Then came Carvytki: a CAR-T infusion that appears to cure some patients who have failed treatments. worksinprogress.co/issue/the-bl...

The blood cancer that became solvable

Multiple myeloma is brutal. We may finally have a cure, but American regulatory inertia means that it was discovered abroad.

Wild animal vaccines are a thing. In 1978, Switzerland airdropped 4,000 vaccine-laden chicken heads from helicopters over the Alps. And it worked: fox rabies was eliminated. Read more about why we should vaccinate wild animals at @worksinprogress.bsky.social worksinprogress.co/issue/why-we...

Vaccinating wild animals can protect human health, and spare animals from extinction and suffering.

New post! It may seem ambitious to ask for individual patient data from clinical trials to be shared, anonymized, for use by other researchers. But the history of medicine shows us that clinical trials have already undergone a series of transformations that once seemed equally bold:

Clinical trial reforms that once seemed radical

How randomized controlled trials, preregistration, and results reporting became standard practice.

This is a really good post. It’s worth reading even if you’re not a health research geek. I find it incredibly useful when someone gives me a sense of how stuff works in a field I am not familiar with, at least not on a suitably granular level, and this post does that.

Great post @ruxandrabio.bsky.social on FDA’s refusal to review Moderna’s flu vaccine, changing its position on what trial design was acceptable. Regulatory uncertainty doesn’t just mean missing out on this vaccine, but also reduces future R&D investment: clinicaltrialsabundance.blog/p/the-modern...

Adding to the confusion, entrepreneur Dr. Jing Liang noted on X that publicly available trial data appear to show Moderna conducted analyses involving higher-dose comparators in older adults. If accurate, it would raise further questions about the basis for issuing a refusal-to-file letter in the first place.

No matter which account ultimately proves correct, this episode leaves us with two uncomfortable possibilities. If the FDA changed its regulatory position after years of clinical development, that reinforces a persistent concern about regulatory inconsistency. If, alternatively, Moderna met the agency’s highest level of stated expectations, actually did use a high-dose comparator and still received a refusal-to-file letter, the implications are even more serious, raising questions about transparency and internal coherence at the agency.

Some things are cultural: female babies were left to die of exposure in Ancient Roman times. This would be unconceivable today! In this piece I reply to comments on my previous post abt the role of aristocratic women in the spread of Christianity open.substack.com/pub/ruxandra...
