Molten glass dripped into cold water transforms into an incredibly strong droplet. Yet, when its tail is broken, the entire structure is destroyed.

Cells create their own cholesterol so they should be fine without the transport (or so I’m told)
GPT-Rosalind surfaced a new lead for drug discovery: could restoring cholesterol transport protect neurons from degeneration? DCTN1 is a gene linked to Perry syndrome, a rare neurodegenerative disorder. In mouse-brain data, disrupting it increased expression of genes involved in making cholesterol. GPT-Rosalind suggested a possible explanation: cholesterol may not be reaching where neurons need it. That gives scientists a specific mechanism to test and, if confirmed, a direction for developing new treatments for neurodegenerative disorders. With @perturbai_tx and @scrippsresearch, a team of thousands of GPT-Rosalind agents worked in parallel, connecting gene-expression results from millions of mouse brain cells with scientific literature in just 32 minutes. We’re now expanding this collaboration to identify new drug targets. openai.com/index/scaling-ai-…

I like that the discourse has moved to the point where we don’t even have to discuss *why* someone would be in jail if there were a different president. We just assert confidently that they would be.
On the Bulwak podcast, Kara Swisher says Elon might already be in jail under Kamala Harris, and "he knows what's coming for him." Another one to put in the "what Democrats plan to do if they take power" file: "If Donald Trump loses the House and the Senate, I would worry. I'd be worried if I were him." "So they're going to start investigating again. You think he's not on the list? He's at the top of that list." "He has a very big sense of fate. And I think it's coming for him. And real hard." They're all just saying this stuff out loud now. There are no secrets about what they want to do.

Kara Swisher says Elon Musk might be in jail right now if Kamala Harris was in office and “he knows what’s coming” if Democrats take back power.

Илон Маск предлагает не охлаждать чипы для космоса, а наоборот — пусть работают горячими. Вот в чём настоящий парадокс космических дата-центров. Все думают: «В космосе же −270 °C, чипы будут охлаждаться сами». На деле всё наоборот. В вакууме нет ни воздуха, ни воды, которые могли бы уносить тепло. Вакуум работает как огромный термос: тепло, которое выработал чип, остаётся внутри. Единственный способ от него избавиться — излучать его в виде инфракрасного света с больших радиаторных панелей. И тут начинается жёсткая физика. Чем холоднее радиатор, тем слабее он излучает. По закону Стефана–Больцмана мощность излучения растёт пропорционально **четвёртой степени** абсолютной температуры. Если поднять рабочую температуру чипа всего на 20 % в кельвинах, радиаторы начинают излучать в два раза больше тепла. Значит, их можно сделать в два раза меньше и легче. Именно об этом говорит Маск в видео: «Если увеличить рабочую температуру на 20 % в кельвинах, массу радиаторов можно сократить вдвое. Поэтому в космосе выгодно работать на более высокой температуре». На Земле мы тратим миллиарды, чтобы держать чипы холодными. В космосе выгоднее спроектировать чипы так, чтобы они спокойно работали при 100–120 °C. Тогда радиаторы становятся существенно легче, а стоимость запуска резко падает. Плюс нейросети довольно устойчивы к случайным битовым ошибкам от радиации — для огромной модели несколько перевёрнутых битов почти ничего не значат. Получается, что главная проблема космического ИИ — не энергия (солнце в космосе бесплатное и постоянное), а именно теплоотвод. И Маск предлагает решать его не охлаждением, а температурой. Выглядит почти контринтуитивно, но физика на его стороне.

A retired NASA engineer who had worked on the Space Shuttle program for 25 years was hired by SpaceX at age 62. He described the first week as the most disorienting experience of his professional life. At NASA, a design change required 3 meetings, 2 committees, a review board, and 6 to 18 months of documentation. At SpaceX, his new supervisor said "if it works, build it. If it doesn't, change it by Friday." He sat at his desk after the first day and called his wife. He told her he felt like a man who had been swimming with ankle weights for 25 years and someone just cut them off. He could move. He could decide. He could build something in the morning and test it in the afternoon. The constraint that he had accepted as the nature of aerospace engineering turned out to be the nature of bureaucracy. Within 6 months he had contributed to more design iterations than he had completed in his last 5 years at NASA. Not because he was working harder. Because the time between having an idea and testing the idea collapsed from months to hours. The same brain. The same knowledge. A different operating system. He described a specific moment where he proposed a modification to a Raptor engine component. At NASA, the proposal would have entered a queue. At SpaceX, the modification was machined by the end of the day and tested by the following morning. He watched his idea become a physical object in 18 hours. At NASA, 18 hours would not have been enough to schedule the first meeting to discuss whether to schedule a meeting. He told an interviewer: "I didn't get smarter when I went to SpaceX. I got faster. The intelligence was always there. The system was in the way." The difference between SpaceX and NASA is not talent. NASA has extraordinary talent. The difference is the time between a thought and a test. SpaceX compresses it. NASA elongates it. The same engineer produces 10x more at SpaceX than at NASA because the bottleneck was never the engineer. It was the meetings about the meetings about the work.

I've been hearing people say glucose spikes don't matter as long as your average blood sugar looks fine. Your brain may disagree. Researchers put continuous glucose monitors on older adults for three days and then scanned their brains. The people whose glucose swung up and down the most over 30 minutes to 2 hours had less gray matter in the hippocampus (the brain's memory center) and did worse on cognitive tests. That held even after accounting for HbA1c (the three-month blood sugar average most doctors check). A normal average can hide plenty of spikes and crashes. I'd pay attention to what happens after meals, not just the number on your lab report. Ideally, keep the swings small. And really only a CGM can tell you this.
