Multi-omics: the next arena for big data in biology For the first time in history, we can measure life's ingredients at a large scale: DNA → genomics RNA → transcriptomics Protein → proteomics Can we unite these data modalities and understand them in context of one another?

Most political scientists see the emergence of democracy as either the natural consequence of economic development, or the result of strategic, rational choice. A closer look at history suggests another path. What if, instead, autocrats just slip up? asteriskmag.com/issues/05/demo…

According to this graph by @jean_twenge, college students were less in favor of free speech in 2019 than in any previous year. The peak of free speech was in the 1970s and 80s. It has been all downhill since the late 1980s, when political correctness first arose.

These past weeks have seen a lot of people throw around the term "Global South". But in a world where manufacturing has spread well beyond the West, the old division between Global North and Global South is breaking down. And that's a good thing. noahpinion.blog/p/does-the-not…

AI assistants are trained to give responses that humans like. Our new paper shows that these systems frequently produce ‘sycophantic’ responses that appeal to users but are inaccurate. Our analysis suggests human feedback contributes to this behavior.

One thing people misunderstand about meditation is it’s superlinear. As you progress your sensory clarity and attention gets sharper, helping you let go faster. It’s common for meditators to make more progress in 6mo than their last 10yrs of practice paulgraham.com/superlinear.ht…

Deep in the human unconscious is a pervasive need for a logical universe that makes sense. The real universe is always one step beyond logic

"The Tyranny of the Marginal User" Why consumer software gets worse, not better, over time. Great post from @IvanVendrov, hard to not see it everywhere. "Here’s what I’ve been able to piece together about the marginal user. Let’s call him Marl." nothinghuman.substack.com/p/the-tyranny-…

The fact that most individual neurons are uninterpretable presents a serious roadblock to a mechanistic understanding of language models. We demonstrate a method for decomposing groups of neurons into interpretable features with the potential to move past that roadblock.

A study investigated the effects of different dietary levels of carbohydrates on mitochondrial respiration, but mechanistic conclusions are premature. bit.ly/45UUx3I

Most people don’t realize how much sickness we all lived with before modern medicine. The measles vaccination alone is responsible for half a percent of all US income this year, $76.4 billion. That is just from the reduced disease burden, it doesn’t include reduced medical costs

Fun fact: If you have a good musical ear, you can tell the speed of a passing vehicle by listening to the pitch interval it makes as it goes by. You don't even need perfect pitch since it only depends on the ratio. If you hear more a major third or more, they're speeding!

Price controls did help the G-7 bring down oil prices. But everywhere else, price controls haven't really been tried, and there are some big risks to using them. So let's ease up on the triumphalism. noahpinion.blog/p/price-contro…
