Scientists exploring the links between a spinal cord injury, inflammation and immune function have turned their attention to a genome-level analysis of the gut microbial community, with early study results offering hints at potential new approaches to aid healing.

In mice, refeeding a strain of bacteria that was depleted after spinal cord injury (SCI) lowered inflammation and stabilized weight loss...

Scientists have uncovered seven surprising stages that space rocks go through as they hurtle toward Earth, revealing that melting and violent fragmentation, rather than simple evaporation, determine their fate. The discovery could help explain why meteorites scatter across the ground and how dangerous asteroids explode in Earth’s atmosphere.

Scientists have gained a clearer understa...

The liver’s job of clearing harmful substances from the body is so essential that the organ may have implications for addressing unexpected diseases, including Alzheimer’s and heart disease. A promising example comes from new Keck School of Medicine of USC research published in the Journal of Biological Chemistry.

The study, conducted in aged rats, shows that an experimental drug called cinaciguat reverses effects of aging in the liver. This, in turn, may lower the risk of Alzheimer’s disease and clogged arteries...

A research team led by professor Minhae Kwon of the School of Electronic and Electrical Engineering has developed two core next-generation artificial intelligence (AI) technologies that enable AI systems to handle complex, long-horizon tasks more effectively while reducing computational costs and improving safety. The findings address key challenges that have hindered the commercialization of costly AI assistant services as well as the deployment of AI in safety-critical areas such as robotics and autonomous driving. The findings are published on the arXiv preprint server.

AI assistants that receive user instructions and autonomously plan and execute tasks, such as ChatGPT-based agents, are becoming increasingly widespread...
