To replace animal testing with AI, we need MASSIVE human datasets. Today, we're thrilled to share Axiom's new data exploration tool, providing the ability to visually explore the world's largest primary human liver toxicity dataset. Built with Axiom's proprietary wetlab protocols, our dataset includes detailed liver toxicity profiles for over 100,000 distinct molecules. The key to this dataset is our ability to do high-throughput, multiplexed high-content screening with primary human liver cells. Traditionally, toxicity assays either sacrifice throughput or sacrifice biological relevance (using easy-to-grow immortalized cell lines instead of real human cells). We managed to combine throughput, physiological relevance, and multiplexing in one platform. The assays run in a high throughput format using automation, meaning thousands of compound-dose conditions can be tested in one experiment. We achieved this using pooled primary human hepatocytes, which are often fragile and expensive. By systemizing our automation and quality control processes, we were able to run over 120+ batches on the same donor pool with incredible reproducibility and consistency. We did this while integrating many readouts per well, whereas many existing toxicity assays only do a single readout. Our multiplexed approach provides far more data per experiment enabling us to measure 10-20 different toxicity phenotypes such as apoptosis, necrosis, mitochondrial fission, endoplasmic reticulum stress, stress granule formation, microtubules, and more all from a single well on a 384-well plate! The combination of scale, high content information, and data quality is exactly what is needed to train highly accurate AI models in biology. If you're interested, please explore the dataset in the comments below and let me know if you want to chat about the details!

The most detailed 3D reconstruction of a cell ever created. Blows my mind every time. But what exactly are we looking at here? The average human cell contains: ~ 15-20 total distinct organelle types, totalling between ~1-10 million working together per cell. All these nano-machines in the cell are made up of proteins. ~ 8,000-10,000 distinct types of unique proteins, adding up to between 40 million - 10 trillion total proteins making up all those cellular systems. ~ 10,000 - 15,000 distinct types of RNA shuttling information around the cell, totalling up to ~10 million RNA molecules moving around the cell simultaneously. ~ Billions of Lipid molecules packed together into the cell membrane, which is also packed tightly with millions more protein-based nano-machines. And let's not forget billions of lines of DNA information to build and run it all. That's TRILLIONS of of individual molecular pieces working together to make a single cell function. That means there is more complexity in a single cell than humanity's largest cities. And people still believe this wasn't Divinely Designed. This is God's Glory on Display. But to make the point. A cell couldn't have evolved from some nebulous simpler "protocell" because even the simplest cells still require massive complexity. The "simplest" cell ever created was engineered by scientists knocking out pieces of a functional cell until it stopped functioning. Here is what they found is the absolute necessary minimal requirements of a cell to function: - Over ~531,000 lines of coded DNA information - 473 total genes to create hundreds of unique protein products (they later added 19 genes back in because the cell was so weak) - Hundreds of thousands of total proteins all working together - Extensive regulatory networks guiding all these interactions If the cell doesn't have all these systems in place, from the start... it doesn't live. Cell rely on an intricate network of complex systems, which are themselves built from complex interconnected pieces woven together into an incomprehensibly complex web of functionilty. Only intelligence has ever been observed creation vast interconnected systems like this. Life was clearly Created. It couldn't happen any other way.

The term "continual learning" has become overloaded if you see it as an ML problem. One classic thread is about memorization: regularization-based continual learning methods, such as EWC, MAS, and SI, estimate which parameters mattered for previous tasks and resist changing them too much. One modern thread is about adaptation: test-time training and inference-time learning methods, such as TTT, adapt part of the model on the incoming test stream before making predictions. These are sometimes discussed as separate threads. But in modern scalable architectures, I think they are better seen as complementary constraints: a model that learns quickly at test time also benefits from a mechanism for deciding what not to forget. In our #ECCV2026 paper, we study this in large-scale 4D reconstruction: how to build fast spatial memory that can adapt over long observation streams while reducing collapse and forgetting. Instead of using fully plastic test-time updates, we stabilize fast-weight adaptation with an elastic prior that balances adaptation and memory. Key ideas: - Elastic Test-Time Training: Fisher-weighted consolidation for fast-weight updates - EMA anchor weights that provide a moving reference for stability - Chunk-by-chunk inference for long 3D/4D observation streams We show that this scales across large 3D/4D pretraining settings, including both LRM-style and LVSM-style models, and improves reconstruction across benchmarks including Stereo4D, NVIDIA, and DL3DV-140. We release model checkpoints across different design choices: resolution, post-training curriculum, and whether the model uses an explicit 4DGS intermediate representation. - Homepage: - Paper: - Code: - Models: This work is co-led with Xueyang Yu, contributed by Haoyu Zhen Yuncong Yang, and advised by Michigan SLED Lab Chuang Gan.

BREAKING: President Donald J. Trump just signed an executive order implementing Most Favored Nation prescription drug pricing — which will deliver dramatically lower drug prices for the American people. Here's what it does: REDUCING DRUG PRICES FOR AMERICANS AND TAXPAYERS: Today, President Donald J. Trump signed an Executive Order to bring the prices Americans and taxpayers pay for prescription drugs in line with those paid by similar nations. — The Order directs the U.S. Trade Representative and Secretary of Commerce to take action to ensure foreign countries are not engaged in practices that purposefully and unfairly undercut market prices and drive price hikes in the United States. — The Order instructs the Administration to communicate price targets to pharmaceutical manufacturers to establish that America, the largest purchaser and funder of prescription drugs in the world, gets the best deal. — The Secretary of Health and Human Services will establish a mechanism through which American patients can buy their drugs directly from manufacturers who sell to Americans at a “Most-Favored-Nation” price, bypassing middlemen. — If drug manufacturers fail to offer most-favored-nation pricing, the Order directs the Secretary of Health and Human Services to: (1) propose rules that impose most-favored-nation pricing; and (2) take other aggressive measures to significantly reduce the cost of prescription drugs to the American consumer and end anticompetitive practices. GETTING A BETTER DEAL FOR AMERICANS: President Trump is once again taking action to keep pharmaceutical manufacturers from charging Americans high drug prices while giving steep discounts to other wealthy nations. — According to recent data, the prices Americans pay for brand-name drugs are more than three times the price other OECD nations pay, even after accounting for discounts manufacturers provide in the U.S. — The United States has less than five percent of the world’s population, yet funds roughly 75% of global pharmaceutical profits. — Drug manufacturers discount their products to gain access to foreign markets and then subsidize those discounts through high prices charged in America—in essence, Americans are subsidizing drug-manufacturer profits and foreign health systems, despite drug manufacturers benefiting from generous research subsidies and enormous healthcare spending by the U.S. Government. — In his first term, President Trump took historic action to keep Medicare and seniors from paying more for drugs than economically comparable countries, which the Biden Administration rescinded before it could take effect. — Instead of fixing this problem, the Biden Administration’s greatest achievement was to negotiate prices that were, on average, 78 percent higher than in 11 comparable countries as part of Biden’s effort to “beat Medicare.” DELIVERING ON PROMISES TO PUT AMERICAN PATIENTS FIRST: President Trump is delivering on his promise to once again put America first by furthering efforts to get American patients and taxpayers a fair deal for prescription drugs. — This Order builds on actions from President Trump’s first term to make progress on reducing price disparities at home and expands those efforts by including Medicaid in addition to Medicare. — President Trump recently signed an Executive Order to take additional action to lower drug prices, including by providing massive discounts to low-income patients for lifesaving medicines, facilitating importation programs, and increasing the availability of generic and biosimilar medicines. — President Trump is also working to make drug prices radically transparent, as he recently signed an Executive Order to build on his historic price transparency efforts undertaken during his first term. — President Trump has been relentless in his effort to address the unfair and outrageous prices Americans pay for prescription drugs: — President Trump: “In case after case, our citizens pay massively higher prices than other nations pay for the same exact pill, from the same factory, effectively subsidizing socialism aboard [abroad] with skyrocketing prices at home. So we would spend tremendous amounts of money in order to provide inexpensive drugs to another country. And when I say the price is different, you can see some examples where the price is beyond anything — four times, five times different.”

🚀 A better, faster co-folding-based binding affinity model. Predicting how tightly a drug candidate binds to its target is critical in drug discovery. It also requires massive computational resources. State-of-the-art models can take 20 seconds to a minute per prediction, impractical for the demands of large scale early-stage programs . 💠 Today, Recursion’s Valence Labs is releasing Nesso-1: the fastest open-source co-folding-based binding affinity model available. At 1 second per prediction, it’s roughly 20x faster than our previous collaboration on Boltz-2 while matching or surpassing its accuracy across public and internal benchmarks. By leveraging NVIDIA Healthcare cuEquivariance, we’ve been able to further accelerate both training and inference by an additional 2-3x. We look forward to continuing to improve Nesso-1 in collaboration with NVIDIA. Weights and code are fully open-sourced. The core architectural ideas behind Nesso-1 build on the insight that coarse-grained co-folding representations can match full-atom models for affinity prediction at a fraction of the cost. Nesso-1 is the first open implementation of this approach with no proprietary dependencies, trained entirely on public data, built to be reproducible and extensible. We’re already using Nesso-1 internally in active drug discovery programs. Fast, reliable affinity prediction at scale is foundational to the kind of autonomous design loops that define our vision for Autonomous Precision Design and Nesso-1 is a meaningful step toward that. 👉 Report: 👉 Github: 👉 HF:

Depth Any Video with Scalable Synthetic Data AI physicists and chemists continue to make strides in depth estimation from video. Check out this new paper featuring some impressive examples. See the thread for more details (unfortunately no code yet). Abstract: Video depth estimation has long been hindered by the scarcity of consistent and scalable ground truth data, leading to inconsistent and unreliable results. In this paper, we introduce Depth Any Video, a model that tackles the challenge through two key innovations. First, we develop a scalable synthetic data pipeline, capturing real-time video depth data from diverse game environments, yielding 40,000 video clips of 5-second duration, each with precise depth annotations. Second, we leverage the powerful priors of generative video diffusion models to handle real-world videos effectively, integrating advanced techniques such as rotary position encoding and flow matching to further enhance flexibility and efficiency. Unlike previous models, which are limited to fixed-length video sequences, our approach introduces a novel mixed-duration training strategy that handles videos of varying lengths and performs robustly across different frame rates 0 - even on single frames. At inference, we propose a depth interpolation method that enables our model to infer high-resolution video depth across sequences of up to 150 frames. Our model outperforms all previous generative depth models in terms of spatial accuracy and temporal consistency.

over the weekend, i built an app that i sincerely hope you will never have a need for, but if you do happen to need a friendly, free, private mri viewer designed to make it easy for you to track tumor progression, you can try it here: here's the story: as some of you may know, last last september, my six year old daughter mira was diagnosed with an extremely rare brain tumor called an adamatinomatous craniopharyngioma, and since then our family has been doing everything we can possibly do to find a cure for her. we tortured chatgpt deep research, put together our own private research team, raised $1.4M and donated it all to Hankinson-Mitra Lab research thanks to $MIRA, explored every remotely applicable drug whether on the market or not, and even began working with md anderson to develop a personalized vaccine that we hope can lead to a more permanent cure unfortunately, we received the devastating news last march that the tumor has continued to grow since her initial surgery, and we had to start to consider more drastic options which would have seriously impacted mira’s quality of life. thankfully, with the help of dr. sabine mueller UCSF Benioff SF and the Hankinson-Mitra Lab at the university of colorado, in april, we started her on an alternative but extremely experimental treatment for this disease. to our unimaginable relief, her tumor has responded extraordinarily well to this treatment which combines tocilizumab (an arthritis drug that blocks IL6 receptors) with avastin (a colon cancer drug that inhibhits VEGF proteins). we know this, because mira gets an MRI scan of her brain every few months. and every time we get a new scan, the first thing we do is compare it against her last scan. so we have to find the matching weight of the scan, and then find the same plane, and then carefully find the slices of the scan where the tumor is visible, and then find the closest match to last month’s scan, then adjust the zoom, rotation, and brightness / contrast so they all look the same. we got pretty good at this. but it shouldn't be this hard. so i built last weekend using gemini 3 with some gpt 5.2 xhigh. you just import your DICOM MRI files (either zip, files or a folder), and you can align all of your scans across multiple dates instantly, just click and drag a rectangle around the tumor on any image, and it will use some very clever algorithms to automatically align up and find the closest matching slice from all your other scans, match the brightness / contrast, rotation, pan, zoom, and even shear to make sure the registration is as close as possible, and make it as easy to possible to compare tumor progression. it has a grid view so you can see all your scans for the same location all at once, and an overlay view so you can quickly compare two scans visually (by holding down the space bar to toggle quickly between two scans), along with tools to animate your scans both within the same sequence as well as over multiple scans to show progression. there is no server, it runs entirely locally on your browser - nothing ever gets uploaded and it's all open source: if you've found this useful, please consider a donation to the UCSF Benioff SF hospital foundation, who has given us extraordinary care over the past year or so:

Solidus Ai Tech Announcement As we approach the end of the year, we want to share a clear and considered update with our community. The final weeks of the year are shaped by holiday periods, Christmas breaks, and New Year’s downtime. Across the industry, attention drops, teams are offline, and meaningful engagement slows. Launching major products during this window would limit visibility, momentum, and adoption. After internal alignment across the entire team, we have collectively agreed to prioritize impact over timing. We are fully aligned on our goals, our roadmap, and the long-term direction of Solidus AI Tech. 2025 has been a challenging year for many. High volatility driven by geopolitical issues, increased institutional control over markets, and liquidity being pulled from altcoins have tested builders and communities alike. Through it all, our focus has remained unchanged: building real infrastructure, real products, and a sustainable ecosystem. For this reason, our upcoming products, the Compute Marketplace, Agent Forge 2.0, and Vision Makers, are now scheduled for release in early 2026, at a time when attention, participation, and momentum are back at full strength. This ensures each release receives the focus, usage, and traction it deserves. We would like to take this opportunity to wish everyone a Merry Christmas and a happy holiday season. Thank you for your continued support, patience, and belief in what we are building. Further updates will be shared in due course.
