In this lecture, I discuss the context within which the theory I am delineating through this course emerge: that of the cold war. What is belief? Why is it so important to people? Why will they fight to protect it? I propose that belief unites a culture's expectations and desires with the actions of its people, and that the match between those two allows for cooperative action and maintains emotional stability. I suggest, further, that culture has a deep narrative structure, presenting the world as a forum for action, with characters representing the individual, the known, and the unknown -- or the individual, culture and nature -- or the individual, order and chaos.

Half the world's population doesn't have access to basic health care. The answer to bridging this divide lies in pharmacies, which Boris A. Hesser believes can be developed into bonafide centers of community care.

What if we looked at Parkinson's as an neurological electrical problem? Brain researcher Eleftheria Pissadaki and her team study dopamine neurons, the neurons that selectively die during Parkinson's. They discovered that the bigger a neuron is, the more vulnerable it becomes because it simply requires more energy. This new insight is reframing the disease -- and by "finding the fuse box for each neuron" and figuring out how much energy it needs, may help us neuroprotect our brain cells.
