Toward fixing damaged hearts through nanofiber tissue engineering

In the US, someone suffers a heart attack every 34 seconds -- their heart is starved of oxygen and suffers irreparable damage. Engineering new heart tissue in the laboratory that could eventually be implanted into patients could help, and scientists are reporting a promising approach tested with rat cells. They published their results on growing cardiac muscle using a scaffold containing carbon nanofibers

Turkeys inspire smartphone-capable early warning system for toxins

Some may think of turkeys as good for just lunch meat and holiday meals. But bioengineers at the University of California, Berkeley, saw inspiration in the big birds for a new type of biosensor that changes color when exposed to chemical vapors. This feature makes the sensors valuable detectors of toxins or airborne pathogens.
