UT Southwestern Medical Center researchers created new nerve cells in the brains and spinal cords of living mammals without the need for stem cell transplants to replenish lost cells. More specifically, scientists in UT Southwestern's Department of Molecular Biology first successfully turned astrocytes -- the most common non-neuronal brain cells -- into neurons that formed networks in mice. They now successfully turned scar-forming astrocytes in the spinal cords of adult mice into neurons. The latest findings are published today in Nature Communications and follow previous findings published in Nature Cell Biology. (1)

We believe things can be different.
We believe things can change from one thing to another.

And now we celebrate our ability to "change" things into something different, as if Parmenides never existed...
