Print a New Body Part

Researchers at the American Chemical Society
have experimented with using ink containing
human cells. The hope is that in the future they
may be able, through the use of a 3-D printer,
create a new nose, ear or even a knee.
This can make it possible to print cartilage
in different shapes. So far tissue has been
successfully implanted in mice.
The possibility of repairing damage from
accidents and cancer would be amazing.
