Excellent summary by @Dereklowe in @ScienceMagazine with some positive news about immunity to #COVID19 - from what I can tell, two things to note: 1/n
1: antibodies may fade quickly (within ~few months to a few years), but T-cells might stick around way longer and still provide some meaningful protection. 2/n Image
2: there may be some cross-reactive (t-cell?) protection from related coronaviruses, possibly the common cold 3/n Image
Obviously still a lot to learn, but glimmers of hope are worth celebrating! 4/fin

Can #toolsforthought like RoamResearch, Obsidian, and Notion actually help us think better? If so, how?

In our #UIST2024 paper, we distill hypertext patterns from real-world usage that augment sensemaking by addressing temporal + spatial fragmentation of sensemaking
I see this work as complementary to the rich practical wisdom many have shared in the #toolsforthought community - I hope that connecting this wisdom with research on hypertext and sensemaking can enrich our understanding of how these tools can help us think better
If this sounds interesting to you, dig into the paper here:

And come chat with us during/after the "Learning to Learn" session at 3:35p on Wed 10/16 @ #UIST2024!

@Sky_zsy will be presenting!dl.acm.org/doi/10.1145/36…

I get wonderful shared delight from hearing others talk abt deep insights that influence/delight them.

I'm also curious what constitutes "depth" (broad implications, surprise, difficulty, etc.).

Would you share a deep insight that influences/delights you + explain why?
Thought sparked by this snippet from @Noahpinion's interview w/ @VitalikButerin where they get into the reasoning behind the coming switch of Ethereum from Proof-of-Work to Proof-of-Stake: Image
I'll get the ball rolling.

A deep idea that really drives my thinking is.. sth I'm not sure how to express, but it's something like:

The path to progress often requires getting worse in some sense.

#Idea - NLP to do initial clustering/classification of altmetric-aggregated discussion of preprints, to facilitate finding high-signal discussions and critiques of preprints (honestly would want this for any paper!).
Preprint servers already hook into @altmetric to expose mentions of a paper in news/blogs + social media (tweets).

But it links to an undifferentiated list of sources (not titles, citation contexts) - good for signaling "attention", missed opportunity to get real context.
If preprint servers have access to commercial API from @altmetric, classifying (and then clustering, enabling searching by) these mentions is eminently doable (e.g., can frame as a straightforward citation context classification problem, like with @scite and @SemanticScholar)

A striking example of "behind the scenes" of great research: Esther Duflo noted that a crucial enabler of her Nobel-prize-winning work was a masterful synthesis of human resource economics in a handbook chapter.
I... think I tracked down the (141-page!!!) handbook chapter?
And it is indeed wonderful!

What a synthesis indeed of a conclusion!

Clearly identifying progress, and also crucial open problems, deeply grounded in a detailed analysis of the literature.

Some thoughts on search as "table stakes" in #ToolsForThought

Started as a "short thread", turned into a longer thing. Hope you find it helpful!
There's been some good discussion on effective search as a core primitive for tools for thought, and the limitations of existing tools, such as @RoamResearch wrt search.

Example:
@RoamResearch And here:

Friends!

What are your go-to sources of examples / case studies of tech gone wrong (for teaching ethics)?

Bonus points if the start of the story isn't obviously bad to everyone.

Personal examples also welcome!
My starting points:
* @internetofshit
* @AIofShit
* @web3isgreat
One of my go-to personal examples is how I frequently can't put my full legal first name into databases (it's Chu Sern Joel) bc. it's "too long".
