For Better Or worse

I've spent a little time posting about science and discoveries that were silly, or at least had very little impact on our daily lives. This isn't one of those posts. Doctors have now developed a 4-D machine that will 'xray' a human body showing it from a inside view that appears to be standing right in front of you. With these 'virtual humans' organs, muscles, tissue can be analyzed as if it were standing bare before the physician, and even, hopefully soon, patients can view their own internal workings, and problems with their doctor to discuss illness, and injuries and their progress for better, or worse.
