Elon Musk has been hyping up the Tesla pickup truck for several years, promising that it won’t look anything like other trucks on the market. Giertz says she performed the stunt to celebrate Musk’s products, as a Tesla pickup truck would truly be her dream car.

Elastin occurs anywhere in the body that requires stretching and recoil and accounts for the elastic properties of many of the body's tissues. Elastagen produces tropoelastin, a precursor of elastin, by putting the genetic instructions for human tropoelastin into a bacterium. The resulting protein can be developed into topical gels, surgical glue, and could also potentially be used for other applications in stem cell and regenerative medicine research." }, { "role": "assistant", "content": "The human skin replacement that got experts buzzing" } ]
