Where is James Bond when we need him?
The villains James Bond was fighting — Dr. No, Goldfinger, and Blofeld — looked improbable in the 1960s; these miscreants of globalization — part master criminal, part arms smuggler, part terrorist, part warlord —are now the stuff of reality

Sun's growing brightness a threat to Earth
The Sun is slowly getting brighter and warmer; in seven billion years it will engulf Earth — but much sooner, in 1.1 billion years, the Sun will grow 11 percent brighter, raising average terrestrial temperatures to around 50 °C, causing oceans to evaporate; the solution: move Earth away from the Sun

Factories First: Winning the Drone War Before It Starts
Wars are won by factories before they are won on the battlefield,Martin C. Feldmann writes, noting that the United States lacks the manufacturing depth for the coming drone age. Rectifying this situation “will take far more than procurement tweaks,” Feldmann writes. “It demands a national-level, wartime-scale industrial mobilization.”
