Manuel Cebrian and his team just won the Tag Challenge, a State Department-sponsored competition to find five fake jewel thieves in five countries within 12 hours. Team Crowdscanner featured some of the same people who won DARPA's Network Challenge, a strange hunt for red balloons placed around the country.
The path to a better internet begins with engineers rethinking its networks. It might be the only way to keep it free

When the soon-to-be-defunct government of president Hosni Mubarak shut off Egypt's Internet early on the morning of January 28, 2011, it proved the U.S. State Department's working theory: that the arc of history bends toward democracy, but it needs Internet access to get there. One project meant to ensure what Secretary of State Hillary Clinton calls "the freedom to connect" is an "Internet-in-a-suitcase," a kit of wireless routers and software that could be smuggled into an authoritarian country and allow revolutionaries to set up their own local area network (LAN) on the fly.
Super-entities are not just limited to dominance of the globe. Just as the economy is intertwined and largely controlled by a small and powerful core network, so too is your brain. Researchers have long known that some areas of the brain are deeply connected to other regions — but now a team from Indiana University and the Netherlands says these connected brain regions form strong connections to each other, creating a cerebral "rich club."
In 1736 the Swiss mathematician Leonhard Euler ended a debate among the citizens of Königsberg, Prussia, by drawing a graph. The Pregel River divided the city, now Kaliningrad, Russia, into four sections. Seven bridges connected them. Could a person cross all seven without walking over the same one twice?
Without question, Alexander Graham Bell's master invention changed our lives and revolutionized the way we communicate. But science is never satisfied, and so we began a steady stream of improvements to the telephone that took it from rotary dials and operators to the unique problems of autocorrect and Siri's witty retorts. Today, we take a look back at the ever-evolving history of the telephone.
A couple years ago we saw wireless technology that would allow us to see through walls. Now, the same team of researchers, from the University of Utah, is putting that motion detection technology to work monitoring breathing patterns. So not only can the network see through your bedroom wall, it can hear you breathing.
The United States is developing what the New York Times is calling “shadow internet” – a prototype network that can fit into a suitcase and be carried across state borders to provide political dissidents with access to the web in the event that their repressive governments shut down communications. This project is part of the Obama administration’s effort to undermine government censorship.
