The dementia-seizure research. Already read. In your inbox.
What it does
The dementia-seizure overlap is one of the most understudied intersections in aging medicine. New peer-reviewed evidence is published regularly, and most of it never reaches the people closest to these cases. Seagull Pulse changes that. It doesn't replace clinical judgment. It makes sure the evidence exists in the room when you need it. Seagull Pulse is the only weekly digest focused exclusively on the dementia-seizure overlap.

- ASAlzheimer's Buddy: Use Flashing Light and Sound at 40Hz2024 · alzheimersbuddy.com · ▲96
I recently learned about some fascinating research done at MIT for potentially treating Alzheimer’s using light and sound stimulation at 40 hertz. Nothing has been proven yet, but it seemed compelling to me, especially given the safety and simplicity of the treatment (i.e., no drugs, no electrodes, just looking at light and hearing sounds). I wanted to try it myself, but was surprised how hard it was to find something free and easy to use to generate such pulses. Which is odd because I remember some freeware DOS program I tried back in the 90s which did all this kind of stuff (anyone know…
- IMI mapped 8.5M research papers into an interactive atlasJul 2026 · tomesphere.com · ▲85
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…
- OSOpen-Source 8-Ch BCI Board (ESP32 and ADS1299 and OpenBCI GUI)Jan 2026 · github.com · ▲54
Hi HN, I recently shared this on r/BCI and wanted to see what the engineering community here thinks. A while back, I got frustrated with the state of accessible BCI hardware. Research gear was wildly unaffordable. So, I spent a ton of time designing a custom board, software and firmware to bridge that gap. I call it the Cerelog ESP-EEG. It is open-source (Firmware + Schematics), and I designed it specifically to fix the signal integrity issues found in most DIY hardware. I believe in sharing the work. You can find the Schematics, Firmware, and Software setup on the GitHub repo: GITHUB…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
