Comments Off on Google Street View cars are helping scientists spot methane leaks

The Google fleet has been mapping cities around the world for years, making navigation easier for travelers. Now they have an important new responsibility: Google Street View cars will seek out natural gas leaks in urban areas. The data will not only help cities protect citizens from potentially harmful gas leaks, but also help cut accidental greenhouse gas emissions. The project was outlined in a new paper published in the journal Environmental Science and Technology . It’s a collaborative effort between Colorado State University researchers, the Environmental Defense Fund , and Google that involves attaching methane sensors to Google Street View cars.

Experiments found that the sensors had a range of about 65 feet, more than enough to detect leaks in urban settings where pipelines run beneath or near public streets. So far, the cars have found that there may be many more methane leaks in America’s major cities than previously believed. Cities with more modern pipelines were far less likely to have leaks, while Boston —the worst offender—was found to have thousands of leaks, resulting in a loss of about 1,300 tons of gas per year.

Methane is far more potent than carbon dioxide, and leaks could seriously accelerate climate change if they aren’t addressed. Via The Washington Post Images via Wikipedia

Poachers Killed 100,000 Elephants in 3 Years Due to Skyrocketing Ivory Demand

Comments Off on Poachers Killed 100,000 Elephants in 3 Years Due to Skyrocketing Ivory Demand

Africa is experiencing a huge spike in elephant deaths due rising demand for ivory in China and other Asian nations. A new study published Monday in the Proceedings of the National Academy of Sciences reveals that poachers killed an estimated 100,000 elephants across Africa between 2010 and 2012. A decade ago 25% of all elephant deaths were due to illegal killings, however that figure has risen to 65% today – and if it continues it will lead to extinction of the species.

Comments Off on Growing Trees from Seeds: Which Work, Which Won’t

If there are any trees in your area, you may have noticed that a couple of major changes come over them at the end of summer and the beginning of autumn. Branches end up laden with fruit, nuts, seed pods, and cones in preparation for seeding the next generation of trees. These majestic beings have been self-propagating for hundreds of thousands of years, but what if we’d like to harness some of that growing power to start our own food-bearing trees?
