Scientists have uncovered a sweet twist in the body’s fight against cancer. Glucose, best known as the fuel that powers our cells, also helps immune cells called T cells communicate and organize their attack on tumors. By turning sugar into special building blocks, T cells strengthen their internal signals and become far more effective cancer killers. Read more
