When I read papers, I have to jump between multiple tabs to find the dataset, code, videos, peer reviews, and so on. I tried to fix this with this project. It started as a project just for papers on arXiv, but after its initial success on Twitter (got like 1.9k views: the most I have gotten for a post), I have now expanded it to include other openly available papers from PubMed Central, bioRxiv, medRxiv, and eLife. These papers have been linked with their genes, proteins, diseases, drugs, clinical trials, 3D protein structures, code, and cited and similar papers. This project now has four…

The first stage of the new http://thi.ng website is live, an up-to-date & hopefully more useful springboard to the 250+ projects and overview of my opensource activity since 2006... Work is ongoing, collecting & re-organizing projects, assets, documentation and extracting interrelationships (incl. older work & music projects (e.g. http://thi.ng/synstack related), clients/people...). Aim is a proper archive of the past 20+ years of outputs & encounters. This is the first website update since 2015. As the timeline visualizations show,…

Hi this is a work in progress but it works to determine supplement efficacy for 500 conditions at the moment. Things you can do: - search for a condition -> find which supplements are effective -> see which studies indicate they are effective -> read individual study summaries - search for a supplement -> see effectiveness table, dosing, safety, dietary sources, mechanisms of action (+ browse all original sources) let me know what you think

I've been frustrated by existing "magic mushroom dosage calculators": most are either visually rough, only handle cubensis, or hard-code one potency value and ignore species, tolerance, and degradation. So I built Mycodosing.wtf – a research‑informed calculator that tries to do three things better: Models species‑level potency using psilocybin/psilocin/baeocystin mg/g with separate profiles for truffles (and syntetics!). Outputs dose ranges (min/median/max) instead of a single magic number, using per‑species uncertainty factors for real‑world variability. Includes a…

I made a table where you can find out the source/location of factory for where health supplements are made. Then, I spent a year reading product labels so you can save time and money when buying supplements. This is that update. This is still a work in progress but it functions fine. My previous post was a simple database of company data showing ingredient sourcing/location. That took 10 days, this has taken me close to 9 months. BackOfLabel is an extension of that initial interest with dosage information at the product & ingredient level. This update allows sorting by many more…

Link: http://www.distilbio.com DistilBio lets you look up detailed information on drugs, diseases, proteins etc. You can ask questions like "Find drugs which interact with Tylenol, and proteins which are targeted by these drugs", or build more complex queries if you like. While it is targeted at scientists in the life sciences field, we've found that many people like finding out more about drugs they're using, diseases they know about etc. We're continuing to add more data and make it more useful for the layman too. We thought we'd like to show our app to HN users and solicit feedback before…

Hi all! This morning, we released a new Apache 2.0 licensed model on HuggingFace for detecting hallucinations in retrieval augmented generation (RAG) systems. What we've found is that even when given a "simple" instruction like "summarize the following news article," every LLM that's available hallucinates to some extent, making up details that never existed in the source article -- and some of them quite a bit. As a RAG provider and proponents of ethical AI, we want to see LLMs get better at this. We've published an open source model, a blog more thoroughly describing our methodology (and…
