Poets and physicians know that a scarred heart cannot beat the way it used to, but the science of reprogramming cells offers hope—for the physical heart, at least.

A team of University of Michigan biomedical engineers has turned cells common in scar tissue into colonies of beating heart cells. Their findings could advance the path toward regenerating tissue that’s been damaged in a heart attack. (more…)

COLUMBUS, Ohio – Engineers at Ohio State University have invented a new kind of nano-particle that shines in different colors to tag molecules in biomedical tests.

These tiny plastic nano-particles are stuffed with even tinier bits of electronics called quantum dots. Like little traffic lights, the particles glow brightly in red, yellow, or green, so researchers can easily track molecules under a microscope. (more…)
