Scientists have developed an innovative 3D bioprinter capable of generating replacement tissue that’s strong enough to withstand transplantation. To show its power, the scientists printed a jaw bone, muscle, and cartilage structures, as well as a stunningly accurate human ear.

I’m thankful this process could replace the previous way they were approaching the transplantable ear – on the back of a lab mouse. If you are squeamish, do not google image search.
Put down the Q-tip!
Produced by the sebaceous and cerumenous glands in the ear canal, ear wax contains a range of organic compounds, including saturated and unsaturated long-chain fatty acids, alcohols, squalene, and cholesterol. Its precise composition varies between people and will depend on diet, ethnicity, their age, and the environment.
