Read moreResearchers at the GEOMAR Helmholtz Centre for Ocean Research Kiel have studied with computer simulations the long-term global consequences of several 'climate engineering' methods. They show that all the proposed methods would either be unable to significantly reduce global warming if CO2 emissions remain high, or they could not be stopped without causing dangerous climate disruption.

Read moreA group of researchers at the University of Wisconsin Madison is examining alternative materials that can be modified to absorb oil and chemicals without absorbing water. If further developed, the technology may offer a cheaper and 'greener' method to absorb oil and heavy metals from water and other surfaces.

Read moreProducing second-generation biofuel from dead plant tissue is environmentally friendly -- but it is also expensive because the process, as used today, needs expensive enzymes, and large companies dominate this market. Now a Danish/Iraqi collaboration presents a new technique that avoids the expensive enzymes. The production of second generation biofuels thus becomes cheaper, probably attracting many more producers and competition, and this may finally bring the price down.

Read moreDuckweed is a tiny floating plant that's been known to drive people daffy. It's one of the smallest and fastest-growing flowering plants that often becomes a hard-to-control weed in ponds and small lakes. But it's also been exploited to clean contaminated water and as a source to produce pharmaceuticals. Now, the genome of Greater Duckweed (Spirodela polyrhiza) has given this miniscule plant's potential as a biofuel source a big boost.

Read moreResearchers have developed a new type of low-temperature fuel cell that directly converts biomass to electricity with assistance from a catalyst activated by solar or thermal energy. The hybrid fuel cell can use a wide variety of biomass sources, including starch, cellulose, lignin - and even switchgrass, powdered wood, algae and waste from poultry processing.

Read moreWhat role does pre-existing vulnerabilities play for people who experience a climate shock? Does it amplify the effects of the climate shock or is effect negligible? Four Arizona State University archaeologists are looking into this as part of an international team examining how people can be most resilient to climate change when it comes to food security.

Read moreIn today's search for renewable energy sources, researchers are turning to the hi-tech, from solar and hydrogen fuel cells, and the very low-tech. The latest example of a low-tech alternative comes from an age-old industry: paper. A new study reveals a sustainable way to turn the huge amounts of waste from paper production into solid fuel with the added bonus of diverting the sludge from overflowing landfills.
