Synthetic circuits can harvest light energy

Tue, 14 Nov 2017 08:43:00 EST

By organizing pigments on a DNA scaffold, an MIT-led team of researchers has designed a light-harvesting material that closely mimics the structure of naturally occurring photosynthetic structures.(image)



Learning from Photosynthesis

Mon, 13 Nov 2017 11:43:00 EST

The green sulfur bacterium makes its home in the chilly waters of the Black Sea. To eek out its lonely existence, this life form scavenges energy from the feeble sunlight available to it at a depth of over 250 feet.(image)



China Experiences Sharp Drop in Coal-Related Emissions, Study Says

Fri, 10 Nov 2017 10:48:00 EST

Emissions of sulfur dioxide, an air pollutant produced primarily by burning coal, have fallen by 75 percent in China since 2007, while SO2 emissions in India have jumped 50 percent, according to a new study by researchers at the University of Maryland.(image)



New Routes to Renewables: Sandia Speeds Transformation of Biofuel Waste Into Wealth

Fri, 10 Nov 2017 09:48:00 EST

A Sandia National Laboratories-led team has demonstrated faster, more efficient ways to turn discarded plant matter into chemicals worth billions. The team’s findings could help transform the economics of making fuels and other products from domestically grown renewable sources.(image)



No more blackouts?

Thu, 09 Nov 2017 08:09:00 EST

Today, more than 1.3 billion people are living without regular access to power, including more than 300 million in India and 600 million in sub-Saharan Africa. In these and other developing countries, access to a main power grid, particularly in rural regions, is remote and often unreliable.Increasingly, many rural and some urban communities are turning to microgrids as an alternative source of electricity. Microgrids are small-scale power systems that supply local energy, typically in the form of solar power, to localized consumers, such as individual households or small villages.  (image)



Easing the Soil's Temperature

Wed, 08 Nov 2017 13:13:00 EST

Soil characteristics like organic matter content and moisture play a vital role in helping plants flourish. It turns out that soil temperature is just as important. Every plant needs a certain soil temperature to thrive. If the temperature changes too quickly, plants won’t do well. Their seeds won’t germinate or their roots will die.(image)



JRC at COP23: A Cleaner, Greener Planet is Both Possible and Affordable

Wed, 08 Nov 2017 13:01:00 EST

Limiting global warming below the critical 2C level set out in the Paris Agreement is both feasible and consistent with economic growth – and the knock-on improvements to air quality could already cover the costs of mitigation measures and save more than 300,000 lives annually by 2030.(image)
