Children with a deformity called microtia have an intact inner ear but an external ear that fails to develop fully, causing hearing loss. The prevalence ranges from slightly fewer than one to as many as four babies per 10,000 births, depending on the country.3D-printed ear created in lab
The artificial ears were made by producing a digital 3D image of a child's intact ear and feeding that into a 3D printer to produce an ear-shaped mold. Then the scientists injected a gel made of living cow ear cells and collagen (a substance used to make gelatin) into the mold, and out popped an ear.
The whole process took less than two days: half a day to design the mold, a day to print it, half an hour to inject the gel, and 15 minutes to allow it to set.
Then the researchers implanted the fabricated ears on the backs of rats, where the ears grew for one to three months. Creepy as it sounds, it isn't the first time scientists have grown ears on rodents, as a model for naturally growing ears.
In medicine, current replacement ears are made from a Styrofoam-like material or by an Eve-like genesis out of a patient's harvested rib. The latter is difficult and painful, and rarely produces an ear that works well or looks natural.

Pretty cool stuff, probably a bunch of liberal/moderate/normal conservative scientists with a rightwing mob protesting outside.
