In one neighborhood a sinkhole that opened last … Continue Reading

Because wind power is generated only when the wind blows, and solar energy isn’t collected on a cloudy day, technologies that can store extra power when it’s not being used and mete it out when needed are becoming increasingly important.
Since June 2010 six men—three Russians, two Europeans, and one Chinese—have been living in isolation in a 19,423-cubic-foot (550-cubic-meter) “spaceship” outside Moscow, doing maintenance work, conducting experiments, and trying to stave off boredom by playing Rock Band and reading the complete works of Gabriel García Márquez.
Within the past 20 years abundances of the bee species Bombus occidentalis, B. affinis, B. pensylvanicus, and B. terricola have plummeted by up to 96 percent.
The finding is based on a new analysis of more than 73,000 museum collections of bumblebees, which showed where bees had been found over the last century, as well as collections of wild bees across the United States. The study looked at 8 of the 50 known bumblebee species in North America.
A guinea-pig-like mammal’s prehistoric urine may be one of the best tools for understanding climate change in arid regions, scientists announced Tuesday. Already, analysis of crystallized rock hyrax pee appears to contradict some results of current climate models.
In Sacramento, they pick figs, kumquats, and plums from public trees. In New York, they harvest purslane–an edible flower–from the cracks in the sidewalk. Down south, it’s fiddlehead ferns, and just about everywhere, people are picking black walnuts, wild mushrooms, and dandelion greens.
Urban foraging–gathering fruit, vegetables, and other useful things from parks, lawns, and sidewalks–isn’t a new thing. But as more urbanites become aware of the free bounty surrounding them, new issues are–pardon the pun–cropping up. When a public park’s berry patch is raided, whose responsibility is it to make sure there are some left for everyone to enjoy? What about pesticides?
Not too long ago, if you wanted to know what type of seafood was best for the environment, your tools didn’t get any more high-tech than a wallet card or a fridge magnet. But the fridge magnet doesn’t help much when you’re at the grocery store, and wallet cards are easy to leave behind (just … Continue Reading
from National Geographic’s Green Guide If you live in a city, you might have a window box or a pot of tomatoes on your balcony. You might even be lucky enough to have a small backyard garden. But do you compost? Probably not: composting in a small space is tough, not to mention smelly. You … Continue Reading
Amid efforts to cap the seafloor leak, cleanup workers have been using boat-based skimmers to pick up the oil, booms to gather the slick for burning, and chemical dispersants to break the crude into smaller droplets—all parts of the oil-fighting toolkit for decades. Soon, though, tech of the future could be cleaning up spills like this one.
