“Why biological weapons are scary, and what we can do about it” by djbinder
<p> What's the biggest thing you think you can take in a fight? According to a YouGov poll, 6% of Americans reckoned they could beat a grizzly bear bare-handed. But lest you take this as evidence of a, let's say, optimistic national spirit, only 72% thought they could take a rat. I think I could win that fight.</p> <p> What's the smallest thing that could take you? While I like to think that, if cornered, I could take all manner of small rodent, I’m not sure even the brave 6% would take a 10-gram bullet to the brain. They also probably couldn’t win against 300 mg of cyanide, 10 mg of sarin gas, or just 0.1 μg of botulinum toxin, the deadliest known toxin. Numbers this small can be hard to grasp. All three substances are deadly, but the lethal dose of cyanide is more than a million times greater than that of botulinum toxin. A grizzly bear, by contrast, is merely a thousand times heavier than a rat.</p> <p> We are still not close to the most dangerous object of all, pound for pound. A single smallpox virion weighs less than 10⁻¹⁴ grams, less than a millionth the mass [...]</p> <p>---</p><p><strong>Outline:</strong></p><p>(03:29) Smaller, cheaper, scarier</p><p>(06:49) The rest of the arsenal</p><p>(08:39) What can we do?</p><p>(10:22) Appendix: Lethality estimates</p> <p><i>The original text contained 2 footnotes which were omitted from this narration.</i> </p><p>---</p> <p><b>First published:</b><br/> August 3rd, 2026 </p> <p><b>Source:</b><br/> <a href="https://www.lesswrong.com/posts/WusL5mDbtJBjdTxCh/why-biological-weapons-are-scary-and-what-we-can-do-about-it?utm_source=TYPE_III_AUDIO&utm_medium=Podcast&utm_content=Source+URL+in+episode+description&utm_campaign=ai_narration" rel="noopener noreferrer" target="_blank">https://www.lesswrong.com/posts/WusL5mDbtJBjdTxCh/why-biological-weapons-are-scary-and-what-we-can-do-about-it</a> </p> <p>---</p> <p>Narrated by <a href="https://type3.audio/?utm_source=TYPE_III_AUDIO&utm_medium=Podcast&utm_content=Narrated+by+TYPE+III+AUDIO&utm_term=lesswrong&utm_campaign=ai_narration" rel="noopener noreferrer" target="_blank">TYPE III AUDIO</a>.</p>

“OpenAI’s Unreleased Model Astra Solves Ten Major Open Mathematics Problems” by Zvi
<p> Math is hard.</p> <p> Math used to be strangely hard for LLMs. People used to gloat about that. Remember?</p> <p> Math is getting easier. AI is getting more capable. Life comes at you fast.</p> <p> Remember this meme?</p> <p> Why yes. Yes it is.</p> <p> We don’t know the extent to which Astra is a big jump over Fable and Sol in this realm. We do know that Astra can do math. As in real math.</p> <p> OpenAI: We provide new results for the following problems. The results were achieved by an internal version of Astra, our next major model. The total number of tokens needed to find solutions to these problems would cost roughly $2,000 at Sol API rates. These arguments were then prepared into manuscripts by humans with the same model. Afterward, the model formalized each argument in a Lean certificate(opens in a new window). We are also releasing for each solution a model's narration of its thinking process.</p> <ol> <li> High-dimensional sphere packing.

“LessWrong vs. TikTok: Tips for capturing attention in a non-rational space” by Taylor G. Lunt
<p> Here's what I've learned from making TikTok videos every day for the last 60 days.</p> <p> I think posting on TikTok is worthwile whether you want to spread AI safety arguments to an enormous audience, you have something you're passionate about you want to share, or you just want to work on your ability to speak confidently and capture human attention.</p> <p> There's a list of tips at the end of this post, but first I want to talk about TikTok at a high level. TikTok and LessWrong operate very differently, so even if you are great at thorough, written content, you might find some of the things I learned about short-form video surprising.</p> <p> I'm not gonna share my TikTok because I'm embarrassed, but here's some info about my account since I started two months ago:</p> <ul> <li> Highest viewed video: 78.6 thousand views</li> <li> Average views over the last 10 videos: 2071 views</li> <li> Average views over my first 10 videos: 563 views</li> <li> Topics: AI safety, speaking/Toastmasters, interesting facts, AI tips, social anxiety, random fun stuff</li> </ul> <p> My experience creating short-form video was one of regularly being surprised. Videos would do well or flop basically [...]</p> <p>---</p> <p><b>First published:</b><br/> August 3rd, 2026 </p> <p><b>Source:</b><br/> <a href="https://www.lesswrong.com/posts/bL8RoJu5wyLssdxiz/lesswrong-vs-tiktok-tips-for-capturing-attention-in-a-non?utm_source=TYPE_III_AUDIO&utm_medium=Podcast&utm_content=Source+URL+in+episode+description&utm_campaign=ai_narration" rel="noopener noreferrer" target="_blank">https://www.lesswrong.com/posts/bL8RoJu5wyLssdxiz/lesswrong-vs-tiktok-tips-for-capturing-attention-in-a-non</a> </p> <p>---</p> <p>Narrated by <a href="https://type3.audio/?utm_source=TYPE_III_AUDIO&utm_medium=Podcast&utm_content=Narrated+by+TYPE+III+AUDIO&utm_term=lesswrong&utm_campaign=ai_narration" rel="noopener noreferrer" target="_blank">TYPE III AUDIO</a>.</p>
