By the time I went to college, I had only one half-functioning ear drum and no hope of regaining the hearing I’d lost… » 5/15/15 4:00pm 5/15/15 4:00pm

3D Tissue Engineering May One Day Solve Both Impotence And Miscarriage

A study published last week in the journal Biofabrication describes a new technique to build replacements for damaged three dimensional human tissues. The researchers running the study are trying to make an eardrum. But their technique, if successful, might also one day create replacements for complex reproductive… » 5/14/15 6:50pm 5/14/15 6:50pm
