The story of how “Who Let The Dogs Out” ended up stuck in all of our brains goes back decades and spans continents. It tells us something about inspiration, and how creativity spreads, and about whether an idea can ever really belong to just one person. About ten years ago, Ben Sisto was reading the Wikipedia entry for the song when he noticed something strange. A hairdresser in England named “Keith” was credited with giving the song to the Baha Men, but Keith had no last name and the fact had no citation. This mystery sent Ben down a rabbit hole to uncover the true story.

If you heard that there was a piece of technology that could do away with traffic jams, make cities more equitable, and help us solve climate change, you might think about driverless cars, or hyperloops or any of the other new transportation technologies that get lots of hype these days. But there is a much older, much less sexy piece of machinery that could be the key to making our cities more sustainable, more liveable, and more fair: the humble bus. Steve Higashide is a transit expert, bus champion, and author of a new book called Better Busses Better Cities . And the central thesis of the book is that buses have the power to remake our cities for the better.

Deep within the National Museum of American History’s vaults is a battered Atari case containing what’s known as “the worst video game of all time.” The game is E.T. the Extra-Terrestrial, and it was so bad that not even the might of Steven Spielberg could save it.

Vantablack is a pigment that reaches a level of darkness that’s so intense, it’s kind of upsetting. It’s so black it’s like looking at a hole cut out of the universe. If it looks unreal because Vantablack isn’t actually a color, it’s a form of nanotechnology. It was created by the tech industry for the tech industry, but this strange dark material would also go on to turn the art world on its head.

Journalist Sam Bloch used to live in Los Angeles. And while lots of people move to LA for the sun and the hot temperatures, Bloch noticed a real dark side to this idyllic weather: in many neighborhoods of the city, there's almost no shade. Shade can literally be a matter of life and death. Los Angeles, like most cities around the world, is heating up. And in dry, arid environments like LA, shade is perhaps the most important factor influencing human comfort. Without shade, the chance of mortality, illness, and heatstroke can go way up.
