A few months ago I reported on new glasses that let color-blind folks see in full color. Now, there are two more inventions just this month that have the potential to help many people.
The first is a "stem-cell gun" (I didn't make that up) that uses your own cells to create new skin on your body. This could drastically change the way we treat the victims of serious burns. Because brand new skin is growing, there aren't even any scars. You can learn more here.
The other invention is a pen that counterbalances the shaking effects of Parkinson's disease, allowing patients to write again. You can watch the example of a graphic designer who had lost the ability to draw or even write her own name. Learn more here.
