To better understand the migration patterns of American robins, Georgetown University researchers attached “tiny metal backpacks” to them that use an antenna on the International Space Station to pinpoint the birds’ locations within thirty feet. Martin Wikelski, director of the Max Planck Institute of Animal Behavior, described the technology as a harbinger of “an ‘internet of animals’—a collection of sensors around the world giving us a better picture of the movement of life on the planet.”

According to a study published in the American Sociological Review, from 1985 to 2004 the mean number of “close confidants” (people with whom one can discuss important matters) Americans had dropped by nearly a third, from 2.94 to 2.08 people. Similarly, the number of those who said they could not discuss important matters with anyone more than doubled, to nearly 25 percent. “The general image,” the researchers wrote, “is one of an already densely connected, close, homogeneous set of ties slowly closing in on itself.”
