The world’s rail networks

There are some more surprising findings, however. The British attachment to rail travel is clear. It has the world’s 17th largest rail network, at 17,732km, despite being just the 78th largest nation by land area. That figure was once as high as 34,000km.

Romania’s 22,298km network is also impressive, putting it 15th on the list, even though it is only the world’s 81st largest country.

I’ve been thinking about the desolation of the AIBO lately because — well, partly because I think about the desolation of the AIBO all the time, because I am a person with a soul, but also because robots are having a moment.

Spain’s solidarity fridge

“The idea for a Solidarity Fridge started with the economic crisis — these images of people searching dumpsters for food — the indignity of it. That’s what got me thinking about how much food we waste,” Saiz told NPR over Skype from Mongolia, where he’s moved onto his next project, living in a yurt and building a hospital for handicapped children.

An Ohio town where races have mixed freely for more than 200 years

Amid the corn and soybean fields of western Ohio lies a progressive crossroads where black and white isn’t black and white, where the concept of race has been turned upside down, where interracial marriages have been the norm for nearly two centuries. The heavy boots of Jim Crow have never walked here.

Founded by James Clemens, a freed slave from Virginia who became a prosperous farmer, Longtown was a community far ahead of its time, a bold experiment in integration.
