Scientists used cryo-EM to capture 13 distinct structures of the chromatin remodeler SNF2H in action. This research provides a complete view of nucleosome sliding, a key process in gene regulation. https://t.co/PF5duXioK0

Virologists and biophysicists at the UNC School of Medicine have discovered that a type of RNA in #Zika virus can "freeze itself in time" in an effort to make more copies of itself and further its spread in the body.

Most people misunderstand the Central Dogma.

In school, perhaps you were taught it as “DNA → RNA → protein.” But that’s a massive oversimplification.

Francis Crick’s real "Central Dogma" was about what *cannot* happen in a cell. Let’s break it down. 🧵

Scientists have tracked microplastics moving through the bodies of mice in real time

The tiny plastic particles are gobbled up by immune cells and eventually become lodged in blood vessels in the brain

Sometimes the experimental control is messed up – but in a really interesting way! – and it's a great 'night science' trick to make a discovery by recognizing it when it happens.

Fresh out of the press! ✨Check out our new paper on the violent entry of the HIV capsid into the nuclear pore — watch it crack that gate! 🤯 💥 Incredible work from @Beck_Laboratory and @HummerLab

We're thrilled to present ESM3 in @ScienceMagazine. ESM3 is a generative language model that reasons over the three fundamental properties of proteins: sequence, structure, and function. Today we're making ESM3 available free to researchers worldwide via the public beta of an API for biological intelligence.

Trained with over a trillion teraflops of compute, this is the first time a model of this scale has been trained for biology, pushing the frontier of AI for biological discovery and engineering.

ESM3 learns to represent the immense complexity of protein biology, learning from billions of natural proteins. From this training it developed the capability to design proteins, responding to complex prompts combining atomic level details and high level instructions to generate new proteins.

ESM3 can explore protein space far beyond natural evolution. We prompted ESM3 to generate a fluorescent protein at a far distance from any known fluorescent proteins, searching an unknown region of protein space, to discover a new fluorescent protein.

We estimate this is equivalent to simulating five hundred million years of evolution.

Eating too much cake is the sin of gluttony. However, eating too much pie is okay because the sin of π is always zero.

We performed subtomogram averaging on complexes from >3 MDa to ~200 kDa, including 80S ribosomes, Rubisco, clathrin, microtubules, ATP synthase photosystem II, and nucleosomes. Most density maps achieved sub-nanometer resolution!🔬✨ #CryoET #StructuralBiology #VisualProteomics

The good idea comes when one person feels comfortable enough to say something that might make them look stupid and their friend is open enough to recognize its potential.
