Researchers at the University of Hamburg noticed that urban areas have higher populations of hedgehogs than rural areas, so they asked the question: what gives?
I take buses and trains everywhere in the San Francisco area, and I know the city’s bus routes better than I know the UX on my phone. So I had to try Leap, the city’s new private bus service. It was a nice experience in many ways, but I wouldn’t recommend it – and not just because of the $6 price tag.
“You want to see our sensor?” Pierre Forcioli-Conti gestures at a high window that leads to the roof. “You’ll have to climb over Matt’s desk and go out the window.” No problem. I wriggle through the window and climb out on top of the the refurbished 1940s movie theater on Mission Street in San Francisco. It doubles…
It's a wonderful sensation when you encounter something you've seen countless times before, only from a different vantage point. The electric glow of neon signs is familiar in all big cities around the world, but seeing them from the vantage point of photographer Rainer Torrado lends them an entirely new shape.
A digital artist known as Chaotic Atmospheres has run city maps through World Terrain, a software system that simulates real-world geological events like erosion. The results are these evocative "erosion flow maps" that imagine what might happen to cities if they flowed into the environments around them.
Roughly 9,000 years ago, humans had mastered farming to the point where food was plentiful. Populations boomed, and people began moving into large settlements full of thousands of people. And then, abruptly, these proto-cities were abandoned for millennia. It's one of the greatest mysteries of early human civilization.
It's been a quarter of a century since the Berlin Wall was torn down, and the city is still marked by the architectural remains from a generation of Soviet occupation. A new study of the city's residents suggests that east and west Berlin remain culturally divided too — though they are still happy with their lives…
Assuming we don't destroy ourselves in a mountain of toxic garbage, humans are going to start building more sustainable, environmentally-friendly cities. And that means a lot more animals will be sharing our cities with us. Here's a glimpse of what that might mean.
In Latvia, a group of bicycle enthusiasts decided to show the city of Riga what it would be like if every bicycle turned into a car. So they built these amazing contraptions, and reminded everyone that cars are what cause traffic jams.
As cities grow, their populations become more diverse — on a species level. As we move into the future, many wild animals will be living in urban areas alongside humans and their pets. Now, urban planners are figuring out new ways to make urban species diversity possible — without killing anyone.
It's one thing to know that cities are growing larger, and that over half the human population lives in a city. But when you see these maps charting the growth of megacities since the early 1900s ... well, it's stunning. It's especially incredible when you realize most cities exploded in size over the past 50 years.
Have you ever been caught in a "phantom traffic jam," where cars have slowed down and even stopped for no reason at all? These are a real phenomenon, and they can be hotspots for accidents. In Nautilus, Benjamin Seibold reports on some possible reasons for these mysterious events.
We have just entered the Urban Age, when the majority of the world's population lives in cities. Most of us may live in the metropolis, but these miracles of engineering and cultural productivity are almost impossible to understand. These ten books will help you untangle the mysteries of today's city life.
The signs of a dying city are usually all too obvious. Houses and landmarks stand vacant, their walls crumbling into ruin; businesses are failing while residents' incomes drop; and young people are fleeing in droves to seek jobs elsewhere. But there are also ways to revitalize a city, and reverse its decline.
This tent could one day be your home. It will provide you with shelter from the elements, food, energy, and purified water. Meet the Urban Algae Canopy — perfect for all your environmental apocalypse needs.
At the heart of many cities are its public transit systems, which help people get to work and get out of town. Some of the greatest public transit systems aren't just large — they also offer their riders something extra, or reshape the cities they serve. Here are some incredible public transit systems around the world.
This enormous building looks like a marine invertebrate has devoured the intersection of two major train lines in Queens. It's part of a futuristic proposal to convert this transit hub into high density housing and live-work spaces. The thing is so crazy it just might work.
For over a hundred thousand years, humans evolved in small, roving bands of a few dozen people. But then, about ten thousand years ago, we started living in cities that were far bigger than any tribe or band. Our minds had to change to cope with the population overload.
There is a truism, often bolstered by pseudoscience, that people in the country are healthier than people in the city. Certainly there are many health problems associated with the metropolis. But it turns out that urbanites are often in better shape and live longer than their rural counterparts.
Terrorists have detonated a low-yield nuclear warhead in your city. How long should you hide, and where, to avoid the worst effects of radioactive fallout? We talked to Lawrence Livermore National Laboratory atmospheric scientist Michael Dillon to find out.
