Nano fiber feels forces and hears sounds made by cells

Engineers at the University of California San Diego have developed a miniature device that's sensitive enough to feel the forces generated by swimming bacteria and hear the beating of heart muscle cells.

Muscle-powered bio-bots walk on command (w/ Video)

(Phys.org) —A new generation of miniature biological robots is flexing its muscle. Engineers at the University of Illinois at Urbana-Champaign demonstrated a class of walking "bio-bots" powered by muscle cells and controlled ...

Gene alteration in mice mimics heart-building effect of exercise

By tweaking a single gene, scientists have mimicked in sedentary mice the heart-strengthening effects of two weeks of endurance training, according to a report from Dana-Farber Cancer Institute and Beth Israel Deaconess Medical ...

High vinculin levels help keep aging fruit fly hearts young

Our cells tend to lose their shape as we grow older, contributing to many of the effects we experience as aging. This poses particular problems for the heart, where aging can disrupt the protein network within muscle cells ...
