This scientist is helping build a missing map of childhood

In 2017, Deanne Taylor attended a presentation at the University of Pennsylvania, just a short walk from her office. A researcher was there to unveil the Human Cell Atlas, an ambitious project that aimed to map every cell in the human body. Taylor was floored, and then concerned. As details emerged, she discovered that the…

Scientists just created female clones of male mice

Scientists have deliberately turned male mouse embryos into females for the first time. A team based in Japan used a CRISPR-based approach to remove the Y chromosome from male cells and create female clones of male mice. “No one has done this before,” says Monika Ward, a reproductive biologist at the University of Hawaii, who…

Of course the ChatGPT dog cancer vaccine spawned a startup

Remember that much-hyped story about an Australian tech entrepreneur using ChatGPT, Grok, and other AI tools to craft a personalized cancer vaccine for his dog? Well, surprise: he's launched a startup. That entrepreneur is Paul Conyngham, who says he is launching Gamgee to offer "personalised mRNA cancer vaccines for dogs." But his ambitions go well […]

How I Built a Self-Hosted Family AI Health Steward (Your Health Data, on Your Shelf)

TL;DR — I built and open-sourced AI Health Steward , a self-hosted, private AI health manager for families. It reads photos of lab reports with multimodal LLMs, builds a structured per-person health profile, shows trends on a dashboard, and answers health questions grounded in your actual data — all running on your own server. Privacy isn't a feature; it's the whole point. Star it on GitHub . The problem: your health data is a product Every family has a shoebox — or a folder — of medical reports: blood tests, blood-pressure logs, prescriptions, scan findings. And every "convenient" health app wants to hold those records for you. But hold them where ? On someone else's cloud, to be monetized, analyzed, or lost when the startup pivots. Health records are the most sensitive data you own. They shouldn't be a product. They should live on your shelf. So I built the opposite: a self-hosted AI health steward where the data never leaves your server. What it does 📄 Take a photo of a lab report → structured data. A multimodal LLM extracts key metrics (BP, glucose, lipids, CBC…) with your confirmation before anything is filed. 🧬 A person-level health profile as the single source of truth — basics, metrics, diagnoses, medications, allergies, lifestyle, family history, and data provenance (where each value came from). 📈 Trend visualization with anomaly markers and clinical critical-value alerts (e.g. BP ≥ 180/110 triggers a "see a doctor" banner). 💬 AI consultation grounded in real data — not a generic chatbot. Intent routing + function calling means answers reflect your profile, not Wikipedia. 🗓️ Personalized checkup plans via a 1+X+Y framework, with budget tiers and safety/contraindication screening. 📋 Periodic health summaries (weekly/monthly/yearly), risk scales (PHQ-9, GAD-7, diabetes, ASCVD), and follow-up/medication reminders . 🧠 RAG over your own history — archived reports are vectorized so you can ask "what did my A1C trend look like over 3 years?"
