    The Best-Looking Laboratory-Grown Ear Yet

    What's this? It's a life-size ear, bioengineered from cow and sheep tissue.
    It may not look like something you'd want to have sticking out of your head. Nevertheless, its geometry is closer to life than a previous effort at bioengineering an outer ear, its creators say. In 1997, a team of surgeons from the Children's Hospital in Boston earned fame for engineering a small ear and implanting it in a mouse. One researcher, Harvard Medical School surgeon Joseph Vacanti, was involved in both efforts.
    This time, the team created an adult-size ear and implanted it onto a rat. The point of the implantation is to check that the ear doesn't lose its shape after implantation and healing.
    Although the latest ear clearly has some ways to go, its creators hope that one day, they'll be able to engineer outer ears for people who are born with deformed ears or who lose their ears in accidents, the BBC reports.
