Juicing the Brain

The military is experimenting with drug therapy, electorstimulation and other methods for inhibiting fear, improving cognition, and reducing the need for sleep while asking "whether we should use new discoveries in neuroscience and other fields such as genetics to improve ourselves, our descendants and perhaps even the species. If it becomes acceptable to enhance civilians, then it would be hard to explain why national security agencies should be barred from giving war fighters an edge. And if it is not acceptable to enhance civilians, a special case might still be made for tuning up military personnel." /Scientific American/
