NASA Evaluates Impact of Climate Change on Arctic Vegetation

The northern reaches of North America are getting greener, according to a NASA study that provides the most detailed look yet at plant life across Alaska and Canada. In a changing climate, almost a third of the land cover – much of it Arctic tundra – is looking more like landscapes found in warmer ecosystems.

Researchers Study Impact of Hydraulic Fracturing Chemical Spills

Hydraulic fracturing, a widely used method for extracting oil and gas from otherwise impenetrable shale and rock formations, involves not only underground injections composed mostly of water, but also a mixture of chemical additives. These chemicals range from toxic biocides and surfactants, to corrosion inhibitors and slicking agents, and many are also used by other industries.

Researchers Design Solar Collector that Dehydrates Food Products

Scientists at CIATEQ (Advanced Technology Center) in Mexico have developed a flat solar collector that utilizes solar energy to dehydrate food products, like fruits and vegetables. Developed at the behest of an agro-food company, the system is designed to attain air temperatures as high as 77°C. This latest development could be a major benefit to the food industry.

MIT Professor Discusses Pros and Cons of Using Biofuels

It is still a matter of debate among policymakers and scientists whether biofuels have a place in the list of future clean energy portfolios although they are being studied as an energy source over many years. This dispute has led to the exploitation of other clean technologies like solar and wind which has overtaken the use of biofuels in actual practice. Biofuel developments are still not underway, because of their inherent drawbacks in terms of acceptance and feasibility.

Fraunhofer Researchers Develop New Camera Technology that Can Detect Black Plastics According to Type

Recycling black plastics, such as those found in car instrument panels, used to be impossible because their absorption properties made them simply invisible to typical analysis systems. But Fraunhofer researchers have developed a new technology that can sort black plastics according to type – and at affordable prices.
