Electric Currents Heal Wounds

150 years ago, German physiologist Emil Du Bois-Reymond discovered that electric currents could speed up the healing of flesh wounds. But his research has been ignored ever since. Until now...

Now Josef Penninger of the Austrian Institute of Molecular Biotechnology in Vienna and Min Zhao of the University of Aberdeen, UK, have demonstrated that natural electric fields and currents in tissue play a vital role in orchestrating the wound-healing process by attracting repair cells to damaged areas.

The researchers grew layers of mouse cells and larger tissues, such as corneas, in the lab. After "wounding" these tissues, they applied varying electric fields to them, and found they could accelerate or completely halt the healing process depending on the orientation and strength of the field (Nature, vol 442, p 457).

Nova's Trip to Edge of Space

  • Stepsedgestratosphere
    In 1999 I flew to the edge of space with the Russian air force, with Space Adventures. I made it to an altitude of just under 100,000 feet and flew at Mach 3 in a Mig-25 piloted by one of Russia's best test-pilots. These pics were taken by Space Adventures from similar flights to mine. I didn't take digital stills -- I got the whole flight on digital video, which was featured on the Discovery Channel.

Nova & Friends, Training For Space...

  • Img021
    In 1999 I was invited to Russia as a guest of the Russian Space Agency to participate in zero-gravity training on an Ilyushin-76 parabolic flight training aircraft. It was really fun!!!! Among other people on that adventure were Peter Diamandis (founder of the X-Prize and Zero-G Corporation), Bijal Trivedi (a good friend of mine, science journalist), and "Lord British" (creator of the Ultima games). Here are some pictures from that trip...

People I Like

  • Peter F. Drucker
    Peter F. Drucker was my grandfather. He was one of my principal teachers and inspirations all my life. My many talks with him really got me interested in organizations and society. He had one of the most impressive minds I've ever encountered. He died in 2005 at age 95. Here is what I wrote about his death. His foundation is at http://www.pfdf.org/
  • Mayer Spivack
    Mayer Spivack is my father; he's a brilliant inventor, cognitive scientist, sculptor, designer and therapist. He also builds carbon fiber trimarans in his spare time, and studies animal intelligence. He is working on several theories related to the origins of violence and ways to prevent it, new treatments for learning disabilities, and new theories of cognition. He doesn't have a Web site yet, but I'm working on him...
  • Marin Spivack
    Marin Spivack is my brother. He is the one of the only western 20th generation lineage holders of the original Chen Family Tai Chi tradition in China. He's been practicing Tai Chi for about 6 to 10 hours a day for the last 10 years and is now one of the best and most qualified Tai Chi teachers in America. He just returned from 3 years in China studying privately with a direct descendant of the original Chen family that created Tai Chi. The styles that he teaches are mainly secret and are not known or taught in the USA. One thing is for sure, this is not your grandmother's Tai Chi: This is serious combat Tai Chi -- the original, authentic Tai Chi, not the "new age" form that is taught in the USA -- it's intense, physically-demanding, fast, powerful and extremely deadly. If you are serious about Tai Chi and want to learn the authentic style and applications, the way it was meant to be, you should study with my brother. He's located in Boston these days but also travels when invited to teach master classes.
