The stress hormone cortisol disrupts the brain's navigational system. It impairs the function of the grid cells that play a crucial role in orientation. This has been verified by researchers from Ruhr ...

A trumpet-shaped, single-celled organism seems able to predict one thing will follow another, hinting that such associative learning emerged long before multicellular nervous systems ...

Scientists have successfully connected living human brain cells to a computer system and taught them to interact with the classic video game DOOM. The strange experiment marks a new step toward ...

In a new study, scientists successfully trained a brain organoid derived from mouse stem cells to solve an engineering benchmark known as the “cart-pole problem.” By applying weak or strong electric ...

Abstract: This article introduces a sustainable human-guided reinforcement learning (RL) framework to address the challenge of learning performance degradation when the human guidance is suspended.

Abstract: Achieving natural, robust, and energy-efficient locomotion remains a central challenge for humanoid control. While imitation learning enables robots to reproduce human-like behaviors, ...

Nucleotide synthesis—the production of the basic components of DNA and RNA—is essential for cell growth and division. In most animal cells, this process depends closely on properly functioning ...

A multidisciplinary team led by MUSC Hollings Cancer Center researcher Sophie Paczesny, M.D., Ph.D., developed an AI-based tool that can identify patients at higher risk for serious post-transplant ...
