The human leg adjusts stiffness during hopping, revealing a surprising muscle behavior

When you hop, run or jump, your legs behave like springs, absorbing and returning energy with each step. But what happens to your muscles and tendons to make this possible? Associate Professor Daisuke Takeshita and doctoral student Kazuki Kuriyama from the Department of Life Sciences at the University of Tokyo have revealed the way our legs adapt to fast movements.

Study establishes cell death as a driving force in glioblastoma

Glioblastoma, one of the most aggressive and lethal brain cancers, has a five-year survival rate of only 6.9%, according to the National Brain Tumor Society.
