Silk bio-ink could help advance tissue engineering with 3-D printers

Advances in 3-D printing have led to new ways to make bone and some other relatively simple body parts that can be implanted in patients. But finding an ideal bio-ink has stalled progress toward printing more complex tissues with versatile functions. Now scientists have developed a silk-based ink that could open up new possibilities toward that goal.

Engineering a permanent solution to genetic diseases

New research demonstrates a new technology advancing the field of genome engineering. The method significantly improves the ability of scientists to target specific faulty genes, and then 'edit' them, replacing the damaged genetic code with healthy DNA.
