Correction: 3-D Printing Meniscus for Your Knee

A physician surgeon friend enlightened me about the story I posted last week. I was not 100% accurate in what I wrote. I always appreciate feedback about my blog posts, especially if it highlights an error on my part. The following is what he said. John, I’ve been meaning to respond to the e-mail from you […]

Back surgery sometimes results in an infarction of a nerve. If the nerve does not grow back, the result can be a drop foot condition. Over time, the leg muscle atrophies. If you walk around Florida, you can see more than a few cases of gentlemen in shorts with one leg noticeably smaller than the […]

Pluripotent Stem Cells

Embryonic stem cells have faced controversy for years. Less well known are adult stem cells found in various tissues. Of particular interest are pluripotent adult stem cells. These stem cells can differentiate themselves under certain conditions to transform into different cell types such as skin, muscle, bone, etc. The potential benefits of being able to […]

Graphene Flexes its Muscles

Graphene is amazing. Things it makes possible will seem like miracles. (See prior stories about graphene in the Attitude LLC blog.) In combination with 3-D printing, graphene may accelerate the possibilities for printing human tissues, including organs. A team of biomedical, electrical engineering, and materials science PhDs published an article about how graphene foam can be a scaffold for […]
