Positive and negative memories are stored in different parts of the brain. Additionally, positive and negative memory-formation is associated with vastly different gene expression profiles. This raises the distinct possibility of therapeutic memory manipulation.

Palmer Luckey, founder of Oculus VR, created a VR headset that kills you if you die in the game: Oculus co-founder makes a VR headset that can literally kill you — the new VR headset uses three embedded explosive charges, planted above the forehead, that can “instantly destroy the brain of the user.” The lethal explosion is triggered via “a narrow-band photosensor that can detect when the screen flashes red at a specific frequency.”

Operation Popeye was a military cloud-seeding project carried out by the U.S. Air Force during the Vietnam War in 1967–1972. The highly classified program attempted to extend the monsoon season over specific areas of the Ho Chi Minh Trail, in order to disrupt North Vietnamese military supplies by softening road surfaces and causing landslides.

Submarines are valued primarily for their ability to hide. The assurance that submarines would likely survive the first missile strike in a nuclear war and thus be able to respond by launching missiles in a second strike is key to the strategy of deterrence known as mutually assured destruction. Any new technology that might render the oceans effectively transparent, making it trivial to spot lurking submarines, could thus undermine the peace of the world. For nearly a century, naval engineers have striven to develop ever-faster, ever-quieter submarines. But they have worked just as hard at advancing a wide array of radar, sonar, and other technologies designed to detect, target, and eliminate enemy submarines. […] Nuclear-powered submarines each cost roughly US $2.8 billion […] the game of submarine hide-and-seek may be approaching the point at which submarines can no longer elude detection and simply disappear. It may come as early as 2050
