GlossaryYoung's modulus (Elastic modulus)

measures material stiffness by stress-to-strain ratio in elasticity

Young's modulus, also known as the elastic modulus, is a measure of the stiffness of a material. It quantifies how much a material will deform under a given amount of stress. Specifically, it is the ratio of tensile stress (force per unit area) to tensile strain (proportional deformation) in the linear elasticity region of the material. This property is crucial in fields like materials science and engineering, as it helps predict how materials will behave under different forces.

in Research/Science 9 upvotes 3 months ago

Topical 2-deoxy-D-ribose (2dDR) regrows hair in mice almost as well as 2% Minoxidil. However, 2dDR may contribute to oxidative stress and hair loss due to the formation of advanced glycation end products (AGEs).
