AI Scientists Design Materials with Autonomous Agents

December 23, 2025 by BBG News

This agentic framework automates materials computation by intelligently selecting and executing predefined workflows-sequences of modular, large language model-driven components handling tasks from parameter generation to command execution-to fulfill user simulation requests and deliver readily interpretable results.

A new framework uses AI agents to automate and accelerate the process of materials discovery through computational experiments.

Decoding the Visual Cortex: A New Model for Adaptive Neural Responses

December 23, 2025 by BBG News

Across a cohort of individual mice-designated F through O and assessed using Dataset-F-an adaptive variational model (AVM) consistently enhanced neural prediction accuracy, as evidenced by improvements in single-trial correlation, trial-averaged correlation, and fraction of explained variance ($FEVE$), demonstrating its robustness beyond theoretical gains and into practical, individual-level performance.

Researchers have developed a novel neural network framework that separates stable visual processing from dynamic adaptation, offering a more accurate and efficient approach to understanding how the brain interprets the world.

Reviving Language Assessment with AI: A Hawaiian Case Study

December 23, 2025 by BBG News

The KĀʻEO item analysis workflow integrates human cultural expertise directly into an AI synthesis-leveraging models like NotebookLM and Claude 3.5 Sonnet-to iteratively refine guidelines and ensure culturally informed content development, effectively positioning humans as active agents <i>within</i> the system rather than simply initial inputs.

Researchers demonstrate a community-driven framework for ethically integrating artificial intelligence into Hawaiian language assessment, balancing psychometric rigor with cultural preservation.

Does Personalized Robotic Gait Really Matter?

December 23, 2025 by BBG News

This exoskeleton features an active body weight support system combined with a six-degree-of-freedom series elastic actuation pelvis module and active hip and knee actuators, enabling controlled and dynamically stable locomotion while incorporating safety features like a fall-prevention harness.

A new pilot study explores whether tailoring an exoskeleton’s movement to an individual’s natural gait significantly improves the user experience during rehabilitation training.

Robots Learn by Watching: A New Approach to Whole-Arm Manipulation

December 22, 2025 by BBG News

The Kinematics-Aware Diffusion Policy (KADP) iteratively predicts denoised 3D node trajectories from encoded visual representations, 3D robot nodes, and time embeddings, subsequently translating these trajectories into joint angle commands via an optimization-based inverse kinematics solver to enable robot motion.

Researchers have developed a novel imitation learning framework that enables robots to more effectively learn complex manipulation tasks by aligning observations and actions in a consistent 3D space.

Skewed Scores: The Hidden Flaws in Medical AI Challenges

December 22, 2025 by BBG News

Medical imaging artificial intelligence systems exhibit systemic biases correlated with the geographical origin of training data-favoring datasets from North America, China, and Europe-as well as the specific imaging task-particularly segmentation-and the imaging modality employed, most notably Magnetic Resonance Imaging ($MRI$).

A new analysis reveals that current medical imaging AI competitions often fail to assess algorithms fairly due to biased datasets and limited data access.

Forest Drones: Navigating the Wild with AI

December 22, 2025 by BBG News

The system navigates three distinct forest environments-difficult, medium, and very difficult-with consistent flight paths achieved at 1 m/s, demonstrating robustness built upon the foundation of $Vins-Fusion$ visual odometry, though each environment inevitably foreshadows limitations in increasingly complex scenarios.

New research details a deep learning system enabling autonomous drones to reliably navigate the complex and challenging environments of dense forests.

Beyond Black Boxes: A New Standard for AI Explainability

December 22, 2025 by BBG News

The PREDICT cardiovascular risk model employs a hierarchical explanation structure-comprising leaf annotations, composition annotations, and global composition-to elucidate complex risk factors and their interrelationships.

Researchers have developed a rigorous, testable framework to move beyond intuitive notions of explainability and formally verify why AI models make the decisions they do.
