3D-printed hearts with 'beating' tissue could ease organ donor shortage

3D-printed hearts with 'beating' tissue could ease organ donor shortage

Scientists at Harvard’s Wyss Institute say they are one step closer to that reality. In lab experiments, they have developed a new technique that uses living human cells to "print" functional heart tissue for an artificial heart — an innovation that could save thousands of lives.

Perovskite LEDs begin to shine

Perovskite LEDs begin to shine

June 7, 2019

In solar cells, the cheap, easy to make materials called perovskites are adept at turning photons into electricity. Now, perovskites are turning the tables, converting electrons into light with an efficiency on par with that of the commercial organic light emitting diodes (LEDs) found in cellphones and flat screen TVs. And in a glimpse of how they might one day be harnessed, Lewis and her collaborators reported in Science Advances a new approach for patterning perovskites for use in full color displays via 3D printing.
