What Happens When A City Tears Down Its Highway?
Five years ago, Seoul, South Korea demolished the Cheonggyecheon Freeway, an elevated highway running through downtown, in a move critics called “crazy”. The results have been nothing short of beautiful. Is there a lesson for other cities? Via Grist:
What he and his colleagues accomplished — tearing down a busy, elevated freeway, re-daylighting the river that had been buried beneath it, and creating a spectacular downtown green space, all in under two and a half years — is nothing short of amazing, not because it actually worked (there was plenty of evidence from other cities to suggest that it could), but because they were able to get public support for it. It’s the stuff urban planners dream about — not to mention a timeline for a major freeway project that would make Seattle drool.
By the early 20th century, as Seoul was burgeoning into the megacity of 10 million it is today,…
Did Literacy Steal Brain Power From Other Functions?
Warning: Reading this may cause parts of your brain to become powerless. From Ars Technica:
The human brain contains many regions that are specialized for processing specific decisions and sensory inputs. Many of these are shared with our fellow mammals (and, in some cases, all vertebrates), suggesting that they are evolutionarily ancient specializations. But innovations like writing have only been around for a few thousand years, a time span that’s too short relative to human generations to allow for this sort of large evolutionary change. In the absence of specialized capabilities, how has it become possible for such large portions of the population to become literate?
The authors of a paper that will be released by Science today suggest two possible alternatives to explain this widespread literacy. Either reading is similar enough to something that our brains could already do that it’s processed by existing structures, or literacy has “stolen” areas of the…
