@thelancet.com sums it up in one sentence:

🔥 Hot take:
The Pentagon has essentially announced that Claude is so much better than other models that they must have it.

Anthropic has signaled that they so much more principled than their competitors, that they can’t.

When the Pentagon backs down or loses this is a huge PR win for Anthropic.

Do you know about ARDS mimics?

These are diseases that *LOOK* like ARDS but have very different treatment: AEP, DAH, OP, HP, EVALI, PJP, AIP, etc.

If you care for people with ARDS but this alphabet 🍜 of disease doesn’t immediately ring a 🛎️ you NEED to give this episode a listen!

Vinay Prasad’s appointment to lead the FDA’s CBER division is a disaster for biotech stocks but it’s worse for patients who depend on new therapies. Therapies that Vinay has signaled he won’t approve.

- readiness to exubate
- breathing trials
- overcoming challenges
- addressing cuff leak
- plus cases

Give it a listen!

I really liked Season 1 of Fallout. One thing that struck me as unrealistic was Vault-Tec’s evil plan: to literally nuke the entire world so they could fundamentally reshape society according to their twisted views.

Anyway, it feels pretty realistic after this week…

NOT-OD-25-080: Rescission of the Final Scientific Integrity Policy of the National Institutes of Health NIH Funding Opportunities and Notices in the NIH Guide for Grants and Contracts: Rescission of the Final Scientific Integrity Policy of the National Institutes of Health NOT-OD-25-080. OD

NIH has rescinded its scientific integrity policy. Hard to see this as anything other than clearing the way for shoddy research on things like vaccines. Regardless of the rationale, it's bad news for public health.

His manuscript was rejected. Then he saw it published by other authors A chemist at a university in Pakistan found a surprise when he opened an alert from ResearchGate on a newly published paper on a topic related to his own work.  When Muhammad Kashif, a chemist…

Person A submits an article. Person B reviews it & rejects it. Then person B changes the author name & submits the article to a different journal where it’s accepted. He claims he attached the wrong file by mistake. 😝

Really great argument for pre-prints!
