Scientists find brain center that 'profoundly' shuts down pain


A research team has found a small area of the brain in mice that can profoundly control the animals' sense of pain. Somewhat unexpectedly, this brain center turns pain off, not on. It's located in an area where few people would have thought to look for an anti-pain center, the amygdala, which is often considered the home of negative emotions and responses, like the fight or flight response and general anxiety.

As Russia stalks US satellites, a space arms race may be heating up


The Georgian conflict proved a far cry from the US military’s GPS-powered assault on Iraqi forces in a 100-hour ground offensive in 1991. For Russia, the conflict signaled the need for a major military upgrade–particularly in the satellite systems critical for navigation, targeting, and communications.

Twelve years and billions of rubles later, Russia is now challenging the United States’ long-standing supremacy in space and working to exploit the US military’s dependence on space systems for communications, navigation, intelligence, and targeting. Moscow is developing counter-space weapons as a part of its overall information warfare strategy. For example, Russia just tested an anti-satellite missile system designed to destroy satellites in low earth orbit.
