The most popular artificial material on Earth isn’t steel, plastic, or aluminum — it’s concrete. Thousands of years ago, we used it to build civilizations, but then our knowledge of how to make it was lost. Here’s how we discovered concrete, forgot it, and then finally cracked the mystery of what makes it so strong.
The World Trade Center Transit Hub—aka The (other) Oculus—has already gone down in history as the most expensive train station, ever. The grand total was $4 billion, about twice what it was supposed to cost, and more than the skyscraper adjacent to it. But there might be another record-breaking figure associated with…
If the ongoing Flint water crisis has taught us anything, it’s that providing clean running water to millions of people is an optional luxury. Wait, that’s not right.
The emergence of new automotive technologies and practices like ride-sharing, on-demand services, and the introduction of autonomous capabilities seems like it would have a diminishing effect on future automotive sales—but studies suggest we may actually see the opposite.
MIT’s researches have been fiddling with virtual models programmed to eliminate traffic lights at intersections with the introduction of fully-autonomous cars, and for the first time I can easily picture how terrifying flying through an intersection with no control just might be.
Four cities could exclusively use rainwater to flush their toilets. But by demanding drinkable water to be pumped to their houses, just so they can poop in it and throw it back out, they are burdening their infrastructure in two different ways.
The long journey to restore safe water to the city of Flint, Michigan has finally begun: The first lead service line was swapped with copper pipe today.
California’s high-speed train has just been delayed by three more years. The first leg of the state’s high-speed rail is now set to finish by 2025, not 2022 as planned. This could mean that Hyperloop—the Golden State’s other, even more futuristic transit plan—could beat the bullet train to the station.
Rivers have long been a center of human activity, but as the global population booms, our impact on these systems is becoming too much to bear. In fact, two-thirds of the 33 largest river deltas on Earth are sinking—some of them at a staggering rate.
America’s roads and bridges are in horrible shape. We could fix them up and provide lots of jobs in the process. But we won’t!
This morning, Flint’s mayor announced an ambitious plan to replace the damaged and dangerous drinking water infrastructure below the city’s streets—and work can begin as soon as next month.
When LA closes a major freeway for construction, the city usually comes up with scary names for it to keep people off the roads. Carmageddon. Jamzilla. This weekend, the city is taking a different approach. The “101 Slow Jam” not only has a cute name, it has a video starring LA Mayor Eric Garcetti doing his best-worst…
After the Super Bowl leaves town, San Francisco can stop vandalizing corporate statues and go back to focusing on more important projects, like imagining the day the Bay Bridge bike path might finally cross the entire San Francisco Bay.
Lead poisoning the drinking water of Flint is the worst possible disaster. It’s a breakdown of urban systems that could’ve been avoided. It’s an instance of smarmy politicians lying to their constituents. It’s one of the scariest stories I’ve had to write about in some time. But it doesn’t mean you shouldn’t trust the…
After lead poisoned the drinking water in Flint, residents received filters they were told would make their tap water safe. Now, tests over the last 24 hours are showing that lead levels in some homes are still too high for a filter to handle.
It’s no secret that San Francisco residents are pissed about Super Bowl 50 invading their city. But now they can take that piss public with the city’s first open-air urinal, where you can pee freely, starting today.
“It may take us a little longer than we said to do this” was the update Dan Richard, chairman of California’s high-speed rail project, gave state legislators yesterday. But the insane infrastructure plan could, shockingly, be less of a cash suck than expected.
We are slowly hurtling towards a dystopian future where cities raise themselves on hydraulic legs to begin the long hunt for resources. Only, in this case, replace cities with greenhouses, and the only resource being hunted here is dry land.
