AI is getting really good at tasks with verifiable rewards namely coding.

Computational biology feels like coding but it is not. Much of biology is about identifying and using symbolic causal representations of how things work, and hierarchical values guiding experiments, data, benchmarks.

Why do schizophrenia GWAS signals look so flat across the genome?

In our recent preprint, we explored why psychiatric disorders — and, more broadly, brain-related traits involving the central nervous system — appear to have unusual genetic architectures.

Agreed! Our family in Texas wouldn't believe us when we said we were happy to grill for them in 30-40 degree weather, and that is actually the best time to do it with the grill keeping us warm....

I really hate it when scientists keep saying that “we need to rebuild trust in science,” because it implies that scientists are to blame for the mistrust rather than the millions of dollars of dark money that have funded political attacks on science in order to advance a far right agenda.

This is functionally a robbery of New York City and New York State taxpayers, who contribute billions more to the federal government annually than we get back.

Stealing our money, blocking our bus lanes.

Myeloproliferative neoplasms in the adolescent and young adult population: A comprehensive review of the literature Adolescents and young adults (AYA) with myeloproliferative neoplasms (MPN) demonstrate notable differences compared to older patients with MPN. With the most common MPN in this group being essential ....

"In this review, we provide a comprehensive overview of the clinical features, disease course and management of AYA patients with MPN and, in doing so, highlight key characteristics that distinguish them from their older counterparts."

Exclusive: Google is indexing ChatGPT conversations, potentially exposing sensitive user data Thousands of shared ChatGPT chats are now appearing in Google search results.

Well this is bad. Google is indexing ChatGPT conversations exposing sensitive user data

I tried a few quick searches. I found someone's chat where I can see their api key

I found some building their resume. Their name, email and phone numbers are exposed.

No, AlphaFold has not completely solved protein folding Biology is hard. Yes, even for AI.

AlphaFold is great, but contrary to public opinion it has not completely solved the protein folding problem. Much work remains to be done.

Seth Rogen goes rogue at science awards show to slam tech billionaires for backing Trump: 'It's amazing how much good science you can destroy with $320 million and RFK Jr' You invite Seth Rogen on stage, you take your chances, as the scientific community recently discovered.

Glad I'm not the only one observing the irony of tech billionaires handing out science prizes while backing an admin that has dismantled American science. New level of #respect for Seth Rogan

Marco Rubio just announced 10 more people were sent to be imprisoned in CECOT. They were flown there from Gitmo to be imprisoned potentially for life based not on any crime for which they were convicted, but on unproven allegations of gang membership with no due process.

This is not lawful.

In our updated TraitGym preprint (w/ @gonzalobenegas.bsky.social & Gökcen Eraslan), we evaluate Evo 2 on regulatory variants associated with human traits. We see marked performance gains with scale on Mendelian traits, although still a bit behind alignment-based methods.

One of the reasons Horror is such an important genre right now — besides the fact that reality is a horror show — is that it’s a genre where people still regularly manage to make original and interesting films and increasingly that’s just not true about filmmaking in general
