His most recent post was about using embryonic stem cells (which is a controversial topic all on its own) and injecting them into blind patients' eyes. The experimental study that he was discussing showed results that showed improvement in the patients' eyesight, even though the study is far from showing conclusive results. Here is the blog post!

Other posts by Dr. Novella include making biofuels (fuel made from plant and animal sources) out of seaweed and other water-based plants, because they are easier to care for, and not as expensive as using land-based plants, which take up farm land and require fertilizier. Plus, the ocean cares for the seaweed, and is vast enough to house the many seaweed plants that could be necessary to make the next type of fuel.
