Reservoirs and hydropower are often thought of as climate friendly, but new research suggests that we may have underestimated the amount of methane they produce. The methane—which is 35 times as potent a greenhouse gas as CO2 over the span of a century—is produced by bacteria eating nutrient-rich agricultural runoff.Read more...

11:00 PM | Shale gas, coal seam gas… what’s the difference?
By Tsuey Cham A few weeks ago we took a look at coal seam gas (CSG) and the hydraulic fracturing (‘fraccing’) process used in its extraction. You may have also heard of shale gas, another type of natural gas found deep underground. So what exactly makes them different? In terms of their gas content they’re […]

6:52 PM | Should Fracking Be Banned?
From KQED Education Do Now: On Tuesday, November 4, 2014 three counties in California will decide by ballot whether or not to ban hydraulic fracturing, otherwise known as “fracking.” It’s steeped in controversy, from the amount of water it uses to how and where that water--and added chemicals--are eventually disposed. Should fracking be banned? Why or why not?

1:45 AM | Toddler does physics-art
As we all know, a scientifically-minded toddler plus a piece of technology can lead to unexpected results. This is the result of Benjamin playing with a retractable steel tape measure at the weekend. How we came to break the case apart I don't know, but the results are pretty (the cellphone shot in poor light doesn't do justice to the artwork):      I like the koru-shape made by the end. The measure has curled itself into a complicated form rather reminiscent of a […]

8:48 AM | DNews: Are We Just 20 Years from a Fusion-Powered World?
Lockheed Martin says it's closing in on a compact nuclear fusion device that will be like a mini-sun, supplying vast amounts of energy from small amounts of water. Nearly unlimited energy from water?! Where do we sign up?

3:24 AM | Four ways to lose weight and feel ‘electric’ this summer
As the mercury rises and our focus turns to hitting the gym and shedding those cuddly winter kilos, we thought we’d take a look at a few ways we could be making our workouts really count. While the idea of working up a sweat and electricity might sound like a recipe for disaster, you’d be […]

3:59 PM | Should you buy a hybrid car?
Last summer we were driving up north, in our Prius, and one of those coal rollers tailgated us for a while, then passed us. On the right. On the median. Jerk. When we were trying to decide whether or not to buy a Prius, last winter, I looked into the usual things one looks into.…

2:09 AM | World Energy Day : Let’s celebrate
World Energy Day has got us thinking. It’s got politicians, engineers and scientists thinking. It’s got the world thinking. The big question is, what does the future of our world look like, and how do we power it? To honour World Energy Day on the 22nd October, we have selected a brand new range of […] The post World Energy Day : Let’s celebrate appeared first on Wiley Asia Blog.

6:40 PM | Satellite Images Reveal How the U.S. Oil Boom Is Creating New Cities
This image from NASA reveals a massive cluster of lights in what was — until recently — desolate prairie. This is the Bakken Shale, an oil-rich rock formation stretching across parts of North Dakota, Montana and Canada. The lights are from the illuminated derricks, local boomtowns and gas flares of the oil fields.Read more...

5:24 PM | What can we do about climate change?
I could rephrase this question. What should we do about climate change. The reason I might rephrase this is because we may not ben that sure of what we can do, but we should do something. Or, more accurately, some things. There are a lot of possible things we can do, and we have little…

3:30 AM | More Electricity In Developing Nations Had Little Impact On Climate Change
Without question American CO2 emissions have plummeted, even after being driven into more coal usage due to political concerns about nuclear energy. Cleaner natural gas made the difference but environmental critics say the energy emissions burden simply shifted to developing nations - poor people can't have air conditioning.  Yet a new study in Nature Climate Change shows that environmentalists don't need to be criticizing the world's poor.  Improving household electricity access in […]

7:05 AM | Understanding Quantum Tunnelling | Jon Butterworth | Life & Physics
Quantum tunnelling sounds like science fiction, and does indeed feature quite often in the genre. But it is real, and plays a role in nuclear fusion, chemical reactions and the fate of the universe. Heres how it worksThe recent claim from Stark Industries Lockeed Martin that a compact fusion reactor could be built soon is, if true, a breakthrough in engineering rather than basic physics. The basic physics of fusion has been known for some time, and a key element of understanding it is […]
