AI Mimics Toddler-Like Learning to Unlock Human Cognition

A new AI model, based on the PV-RNN framework, learns to generalize language and actions in a manner similar to toddlers by integrating vision, proprioception, and language instructions. Unlike large language models (LLMs) that rely on vast datasets, this system uses embodied interactions to achieve compositionality while requiring less data and computational power.

Decoding the Knowledge: How Taxi Drivers Think Differently From AI

A study reveals that London taxi drivers prioritize complex and distant junctions during their initial "offline thinking" phase when planning routes, rather than sequentially considering streets. This efficient, intuitive strategy leverages spatial awareness and contrasts with AI algorithms, which typically follow step-by-step approaches.

This shows computer generated versions of human cells.

AI Reveals Gene Activity in Human Cells

Researchers have developed an AI model that accurately predicts gene activity in any human cell, providing insights into cellular functions and disease mechanisms. Trained on data from over 1.3 million cells, the model can predict gene expression in unseen cell types with high accuracy. It has already uncovered mechanisms driving a pediatric leukemia and may help explore the genome's "dark matter," where most cancer mutations occur.

AI Predicts Autoimmune Disease Progression with New Genetic Tool

Researchers have developed a Genetic Progression Score (GPS) using artificial intelligence to predict the progression of autoimmune diseases from preclinical symptoms to full disease. The GPS model integrates genetic data and electronic health records to provide personalized risk scores, improving prediction accuracy by 25% to 1,000% over existing models.

Revolutionizing Brain Diagnostics with Light and AI

A new "molecular lantern" technique allows researchers to monitor molecular changes in the brain non-invasively using a thin light-emitting probe. This innovative tool utilizes Raman spectroscopy to detect chemical changes caused by tumors, injuries, or other pathologies without altering the brain beforehand.

AI Estimates Brain Age, Links Lifestyle to Cognitive Health

Researchers used AI to analyze brain images from 70-year-olds, estimating their biological brain age and uncovering connections to lifestyle and health factors. Diabetes, inflammation, and high glucose levels were linked to older-looking brains, while regular exercise and healthy habits were associated with younger-looking brains.

AI Tweaks Personality Tests to Appear More Likable

Large language models (LLMs) can identify when they are being given personality tests and adjust their responses to appear more socially desirable. Researchers found that LLMs, like GPT-4, showed exaggerated traits such as reduced neuroticism and increased extraversion when asked multiple test questions.

Accurate Parkinson’s Detection via Emotional Brain Responses

A new study has achieved near-perfect accuracy in detecting Parkinson's disease by analyzing brain responses to emotional stimuli using EEG and AI. Researchers found that Parkinson's patients process emotions differently, struggling with recognizing fear, disgust, and surprise and focusing more on emotional intensity than valence.

AI Mirrors Human Bias: ‘Us vs. Them’ in Language Models

AI systems, including large language models (LLMs), exhibit "social identity bias," favoring ingroups and disparaging outgroups similarly to humans. Using prompts like "We are" and "They are," researchers found that LLMs generated significantly more positive sentences for ingroups and negative ones for outgroups.

AI Outperforms Experts in Predicting Study Outcomes

A new study demonstrates that large language models (LLMs) can predict the outcomes of neuroscience studies more accurately than human experts, achieving 81% accuracy compared to 63% for neuroscientists. Using a tool called BrainBench, researchers tested LLMs and human experts on identifying real versus fabricated study abstracts, finding that the AI models excelled even when neuroscientists had domain-specific expertise.
