Houstonians want walkable neighborhoods

Car-centric Houston tends to be one of our go-to examples for everything that can go wrong with a city, ever. But we may not be able to use the city as a whipping boy much longer. According to a new survey, Houstonians are seeing the light on walkable and transit-accessible neighborhoods. More than half of the people surveyed said they would settle for a smaller home if it meant living near offices, restaurants, and stores. Yes, this is in Texas! To be fair, Stephen Klineberg, who created this survey in 1982, sounded as surprised as we are. He told the …

Deadly tree disease could wipe out California’s citrus industry

Hide ya’ lemons, hide ya’ limes — a deadly disease is coming for California’s citrus trees. State ag experts recently found a tree that tested positive for Huanglongbing–and yes, it is way more serious than its sing-songy name suggests. The bacteria, also known as citrus greening or yellow dragon disease, attacks a trees’ vascular system and kills them off within a few years. The disease has no known cure, and it’s had disastrous impacts on citrus trees in China, Brazil, and Florida. For now scientists have only spotted the infection in a lonely tree, but the situation is understandably sending …

Climate Skeptics

It’s hard sometimes to ignore climate deniers: They’re so wrong! About everything! But the biggest impact they seem to be having is just that: annoying environmentalists. Denialist campaigns have had little influence on the 30 percent of people who are skeptical about climate science, ABC News reports. The one thing that does change those people’s opinions? The weather.

Singapore’s giant supertrees: The ultimate vertical gardens

Singapore is in the middle of a project that looks like a Miyazaki movie come to life. The city’s 18 “supertrees” do everything that normal trees do, only better. They will stretch up to 164 feet tall, grow 200 species of flowers, ferns, and epiphytes, collect solar energy, harvest rainwater, and work as a natural cooling system. Oh, and one of them has a bistro at its summit.

Energy Efficiency

In India, solar-powered ATMs use as much energy as a lightbulb

In urban America, getting money out of the bank means walking a block to the ATM. In rural India, the nearest bank branch might be a day’s journey away. But now a company called Vortex Engineering is using solar power to bring convenient banking to out-of-the-way villages. The key: The company’s ATMs are energy efficient. Vortex calls them the “world’s lowest power consuming ATMs,” and they use just 10 percent of the energy of other banking machines, according to Yale e360. It adds up to about the same amount of energy as a lightbulb. That low energy overheads means that …

Urban Agriculture

Texas college turns football field into awesome urban farm

If your football team can’t hack it on the field, perhaps they can grow some kick-ass kale. At least that’s the sentiment from Dallas’ Paul Quinn College. After the university cut its football program, President Michael Sorrell decided to transform the unused field into a working farm. The WE Over Me Farm, which covers 57,000 square feet, was a response to the lack of healthy food options in the economically depressed area. Highland Hills, the neighborhood where Paul Quinn is located, is a designated food desert.
