Imagine trying to trap a miniature star inside a machine without letting it touch the walls or burn itself out. This is the central, high-stakes challenge of high-temperature plasma engineering.

Practice may do more than make perfect. Researchers found that extensive training physically reorganizes the brain, allowing learned tasks to bypass the prefrontal cortex and run through specialized circuits instead. By freeing the brain's "thinking" center, people became better
