Nuclear Energy: Thorium Reactors

I recently discovered a small gap in my education in nuclear energy. It concerns LFTR reactors. They seem to be reconsidered after uranium based reactors were favored after world war 2 and the during the cold war due to their dual use in energy production as well as the generation of byproducs for nuclear weapons.

There are several videos on the google tech talk channlel, just two of those:

CogSci: Embodied Cognition and Consciousness

Arguing against a Descartian dualism and for a interconnection between brain and body, the article at scientific american blogs gives nice pointers and references for an embodiment point of view of cognition. It's interesting to see if there is some "mind" kind of core in the biomachine that the human being actually is. The normal bio-chemic interconnection between mind and body seems to be quite natural as the mind needs the body to survive (and stay healthy) in order to do so itself.

At the thoughts on thoughts blog you'll find a 3 part post on the possible functions of consciousness which is an interesting topic to think about, especially keeping in mind the aforementioned article:
