Freezing brains!  Now that's my kind of science!

What they really need to do is remove the brains first, then keep them floating at various levels in one giant vat with a big glass wall so you can see them all.  I'm thinking supercooled liquid, maybe pale green, although that's awfully traditional.  I suppose they could go with something more daring like yellow or sky blue.  It also depends on what kind of lights you have flashing on your gigantic instrument panels.  And the uniforms your henchmen wear, of course.

Once they've got the color scheme down, all these brains need to be wired together so they can be turned into processor components for a super-computer that tells the future.  Or at least one that can beat that damn chicken at checkers.

Darpa: Freeze Soldiers to Save Injured Brains
By Katie Drummond, November 13, 2009

The Pentagon's mad science division has a new way to deal with the 70,000+ troops diagnosed with traumatic brain injury: freeze 'em.

Darpa, the military's far-out research arm, is looking for research projects that would create a "therapeutic hypothermia device" to prevent traumatic brain injuries from causing permanent molecular damage to the brain. The idea is based on successful studies that used cortical cooling to treat survivors of strokes and cardiac arrest. According to Darpa's solicitation, cooling down the brain after trauma can offer "dramatic neuroprotection" that will prevent long-term harm to cognition and motor skills...

Too Too Solid Flesh?

Maybe we're not so solid after all:

... there's a growing consensus among scientists that the relationship between us and our microbes is much more of a two-way street. With new technologies that allow scientists to better identify and study the organisms that live in and on us, we've become aware that bacteria, though tiny, are powerful chemical factories that fundamentally affect how the human body functions. They are not simply random squatters, but organized communities that evolve with us and are passed down from generation to generation. Through research that has blurred the boundary between medical and environmental microbiology, we're beginning to understand that because the human body constitutes their environment, these microbial communities have been forced to adapt to changes in our diets, health, and lifestyle choices. Yet they, in turn, are also part of our environments, and our bodies have adapted to them. Our dinner guests, it seems, have shaped the very path of human evolution...

Equally challenging, though in a different respect, will be changing long-held ideas about ourselves as independent individuals. How do we make sense of this suddenly crowded self? David Relman suggests that how well you come to terms with symbiosis "depends on how comfortable you are with not being alone." A body that is a habitat and a continuously evolving system is not something most of us consider; the sense of a singular, continuous self is a prerequisite for sanity, at least in Western psychology. A symbiotic perspective depends on a willingness to see yourself as the product of evolutionary timescales. After all, our cells carry an ancient stamp of symbiosis in the form of mitochondria. These energy-producing organelles are the vestiges of symbiotic bacteria that migrated into cells long ago. Even those parts of us we consider human are part bacterial. "In some ways, we're an amalgam and a continuously evolving collective," Relman says...
