E11 is lighting up the brain. Amazing work!
Andrew Payne@Andrew_C_Payne

@E11BIO is excited to unveil PRISM technology for mapping brain wiring with simple light microscopes. Today, brain mapping in humans and other mammals is bottlenecked by accurate neuron tracing. PRISM uses molecular ID codes and AI to help neurons trace themselves. We discovered a new cell barcoding approach exceeding comparable methods by more than 750x. This is the heart of PRISM. We integrated this capability with microscopy and AI image analysis to automatically trace neurons at high resolution and annotate them with molecular features. This is a key advance towards economically viable brain mapping - 95% of costs stem from neuron tracing. It is also an important step towards democratizing neuron tracing for everyday neuroscience. Solving these problems is critical for curing brain disorders, building safer and human-like AI, and even simulating brain function. In our first pilot study, we acquired a unique dataset in mouse hippocampus. Barcodes improved the accuracy of tracing genetically labelled neurons by 8x – with a clear path to 100x or more. They also permit tracing across spatial gaps – essential for mitigating tissue section loss in whole-brain scaling. Using molecular annotation, we uncover an intriguing feature of synaptic organization, demonstrating how PRISM can be used for systematic discovery 🧵

@owl_posting I definitely can relate to this at the Rothko Chapel in Houston

i saw a Rothko in person while visiting the Cleveland Museum of Art a few months back, and it was a captivating experience. some people don’t get the hype over Rothko, but they also don’t usually get that the most important thing in art boils down to one thing: how big it is. the literal physical size. this isn’t a metaphor, that’s all there is to it. the average size of a Rothko is 5” x 4.3” feet. the largest one exceeds 9 feet tall. some people will tell you that no, it’s actually the immaculate color theory, or the way that he used egg whites in the paint thinner, or that he somehow infused the whole artwork with his profound grief this is all, of course, nonsense. it ignores that we spent our generational past being wary of creatures the size of buildings and rival tribesman with hands big enough to pop our skulls. and it ignores our present, where we spend our earliest years around entities unfathomably large, the biggest thing we have ever seen, yet so consistently gentle in how they wield that size this is all to say: when i see a Rothko, the sheer breadth of it fills me with terror, like it’s going to swallow me alive. but then nothing happens at all, it just patiently sits there, waiting. so then i feel grateful almost nothing else in life treats us this well, so we feel deeply emotional connected to whatever does

A cell is a vibrating, densely packed bag of molecules. The ratios of these molecules are not balanced, however. A typical HeLa cell, for example, has about 20 times more protein than DNA by mass. Why, then, are the methods available to study proteins so much more expensive, and less scalable, than those used to study DNA? Human cells make thousands of different proteins using 20 amino acids. Those amino acids can be arranged in a staggering number of combinations to make everything from small, spindly structures like insulin (51 amino acids) to globular giants such as titin (34,350 amino acids). This chemical diversity is what makes proteins so adaptable and infinitely useful. Ideally, scientists would be able to study the proteomes of thousands of cells in one experiment! And cheaply, too! But in reality, existing proteomics technologies can only be used to analyze about a dozen cells at once — a paltry amount. Modern proteomics is majorly bottlenecked, in other words. And it's a shame, because many of the diseases we care about are influenced by proteins. Protein alterations — like phosphorylation and ubiquitination — can change a protein’s function in ways that are invisible at the level of DNA or RNA. Diseases like Alzheimer’s are partly driven by these changes. And it is exceptionally difficult to study the brain, with its billions of cells, by looking at the proteins of just a few cells each day. For my latest essay in @AsimovPress, I explain how a non-profit organization, called Parallel Squared Technology Institute, is trying to solve this problem. Their goal is to make proteomics as scalable and accessible as DNA sequencing. And remarkably, they are working toward this goal NOT by making better hardware (aka bigger, more expensive machines), but rather by inventing better molecular barcodes, devising protocols to squeeze more data out of mass spectrometers, and writing software to handle all the data. So far, they’ve made a 9-plex barcode system (up from the state-of-the-art 3), and combined it with a time-staggered injection method called timePlex, thus enabling 27-plex experiments on existing machines. Their strategy has already boosted the number of proteomes scientists can study in a single day by a great deal. Now they want to 100x this again. The Parallel Squared team is now applying their tools to study Alzheimer’s. They’re mapping the proteomes of individual neurons taken from patients who died at various disease stages, from Braak 0 to Braak 6. By lining up healthy and diseased cells and watching how protein quantities change, they aim to flag molecular markers that appear before symptoms begin — in the disease’s quiet, prodromal phase, when treatments might still work.
