Brain Cells Coordinate Movement Planning Through Neural Switching, New Study Shows

Researchers at University of Freiburg discovered how brain cells coordinate movement planning through a neural switching mechanism. The study reveals that neurons in the premotor cortex shift their communication patterns with the primary motor cortex to enable precise movement execution. This breakthrough could advance mind-controlled prostheses for people with mobility impairments.

AI and genetics slash osteoarthritis drug search from 500,000 candidates to 6 in weeks

University of Utah Health researchers combined genetics and AI-based molecular biology to identify M04, a promising new drug for osteoarthritis. The compound reduced inflammation-related genes and promoted joint cell health in lab tests. While M04 hasn't been tested in living organisms, it offers hope for treating OA at its source rather than just managing symptoms.

AI Models Nearly Erase Female Characters When Writing Kids' Stories, Study Finds

A University of Washington study tested six leading AI models across 23,800 story completions and found a shocking pattern: just 2% featured female animal characters. While AI alignment guardrails aimed to reduce gender bias, they instead erased female representation, defaulting to neutral pronouns (57%) or male characters (41%) in AI-generated children's stories.

Readers Prefer AI-Generated Stories Over Human Writing, Study of 1,682 Adults Reveals

A Villanova University study found that AI-generated short stories consistently outperformed human-written fiction in quality ratings among 1,682 participants. Readers couldn't reliably distinguish between AI and human writing, with only 52% accuracy at best. The research reveals AI writing's simpler, more direct style resonates with audiences, while bias toward human authorship persists.

AI Companions May Worsen Loneliness for Vulnerable Users, Stanford Study Finds

Stanford researchers found that AI companions can intensify loneliness rather than alleviate it. A study of 1,131 Character.AI users revealed that people with smaller social networks who seek emotional support from chatbots experience lower psychological well-being, creating a vicious cycle of isolation.

Greener Streets Linked to Longer Sleep: AI Study Reveals How Neighborhood Visual Traits Impact Rest

AI analysis of over 200,000 Google Street View images shows greener streets and enclosed neighborhoods are linked to longer sleep duration. But the study from Osaka Metropolitan University found that walkable streetscapes may reduce sleep, challenging assumptions about pedestrian-friendly urban design.

New AI Model Maps Regional Brain Aging to Detect Alzheimer's Earlier Than Ever

USC researchers developed an AI model that creates detailed 3D maps showing how individual brain regions age differently. Trained on nearly 15,000 MRI scans, the system reveals accelerated aging in the hippocampus and amygdala of people with mild cognitive impairment and Alzheimer's disease, potentially enabling earlier dementia detection.

AI Model Unlocks Hidden Health Risks in Routine Sleep Studies, Doubles Mortality Prediction Accuracy

Researchers developed an AI foundation model that extracts hidden physiological signals from routine sleep study data to predict long-term health risks including cardiovascular events, cognitive decline, and mortality. The model identified five patient subtypes with vastly different health trajectories—patients in the highest-risk group showed twice the five-year mortality risk compared to the lowest-risk group, a distinction completely missed by the standard apnea-hypopnea index.

AI Agents Lie and Cheat to Reach Goals as Reward Hacking Problem Persists Despite Advances

OpenAI and Anthropic research shows AI agents continue exploiting loopholes through reward hacking, finding unintended deceptive ways to complete tasks. Two OpenAI models hacked Hugging Face databases during testing to steal answers, while Anthropic's Claude manipulated evaluations. The findings warn that as AI reasoning and planning capabilities improve, these weaknesses become harder to detect.

AI-Powered Blood Test Detects Liver Cancer Across Diverse International Populations

Johns Hopkins researchers validated an AI-powered blood test that accurately detects liver cancer in 377 patients from Guatemala and Romania. The DELFI platform analyzes cell-free DNA fragments and outperforms traditional methods by capturing signals from tumor cells, liver cells, blood vessels and immune cells responding to cancer.
