Last spring, 3,000 British soldiers deployed an invisible automated intelligence network, known as a “digital targeting web,” as part of a NATO exercise called Hedgehog in the damp forests of Estonia’s eastern territories.

The system had been cobbled together over the course of four months—an astonishing pace for weapons development, which is usually measured in years. Its purpose is to connect everything that looks for targets—“sensors,” in military lingo—and everything that fires on them (“shooters”) to a single, shared wireless electronic brain.

Eighty years after total war last transformed the continent, the Hedgehog tests signal a brutal new calculus of European defense. But leaning too much on this new mathematics of warfare could be a risky bet. Read the full story.

Stardust Solutions believes that it can solve climate change—for a price.

The Israel-based geoengineering startup has said it expects nations will soon pay it more than a billion dollars a year to launch specially equipped aircraft into the stratosphere. Once they’ve reached the necessary altitude, those planes will disperse particles engineered to reflect away enough sunlight to cool down the planet, purportedly without causing environmental side effects.

Inside the decades-long fight over Yahoo’s misdeeds in ChinaWhen you think of Big Tech these days, Yahoo is probably not top of mind. But for Chinese dissident Xu Wanping, the company still looms large—and has for nearly two decades.

In 2005, Xu was arrested for signing online petitions relating to anti-Japanese protests. He didn’t use his real name, but he did use his Yahoo email address. Yahoo China violated its users’ trust—providing information on certain email accounts to Chinese law enforcement, which in turn allowed the government to identify and arrest some users.

Xu was one of them; he would serve nine years in prison. Now, he and five other Chinese former political prisoners are suing Yahoo and a slate of co-defendants—not because of the company’s information-sharing (which was the focus of an earlier lawsuit filed by other plaintiffs), but rather because of what came after.
