📰 Latest AI News

AI Spots Dementia Early Through Brain Scans and Movement Patterns

A new study supported by UK Biobank reveals how AI can detect early signs of Alzheimer’s and Parkinson’s years before diagnosis by analyzing brain scans and movement data:

🧠 MRI brain images were key to identifying subtle cognitive changes linked to dementia.
🏃 Activity tracking helped flag motor symptoms, especially for Parkinson’s disease.
📈 The combined approach improved predictions, allowing detection long before symptoms appeared.
💡 Future work may enable population-wide screening and earlier access to treatment and support.

OpenAI Introduces Fine-Tuning for GPT-4o

OpenAI’s latest update makes it possible for enterprises and developers to fine-tune GPT-4o and GPT-4o mini with their own data:

💾 Fine-tuning customizes tone, style, and domain-specific knowledge.
📁 Includes 1M free training tokens/day for GPT-4o (2M for GPT-4o mini) until Sept 23.
📈 Pricing: $25 per million training tokens, inference at $3.75 per million input, and $15 per million output tokens.
💡 Available to all paid tiers, enabling tailored enterprise applications at scale.

💡 Awesome AI Use Case of the Week

Turn YouTube Videos and PDFs into Flashcards with Knowt AI

Knowt lets you upload any YouTube link, PDF, or Google Doc—and instantly generates flashcards, summaries, and quizzes from the content.

Just drag, drop, and learn.
Syncs with Anki and other spaced-repetition tools.
Tracks what you’ve mastered and what needs work.

📚 Great for: Students, online learners, and anyone building their own second brain.

🚀 Surprising AI Breakthrough

AI Digitizes the Sense of Smell

Researchers are using AI to map and reproduce scents by analyzing molecular structures, creating a new field of “olfactory intelligence.”

👃 Graph neural networks decode how molecules correspond to specific smells.
🧠 Applications range from recreating fragrances (like fresh-cut fruit) to designing insect repellents up to 10x more effective than DEET.
🚀 Future uses could include health diagnostics, pollution monitoring, and digital scent experiences.
