Sailing cargo ships can benefit from new aerodynamic tech      (via sciencedaily.com)     Original source 

A research team has demonstrated a unique method that reduces the aerodynamic resistance of ships by 7.5 per cent. This opens the way for large cargo ships borne across the oceans by wind alone, as wind-powered ships are more affected by aerodynamic drag than fossil-fueled ones.

Probe where the protons go to develop better fuel cells      (via sciencedaily.com)     Original source 

Researchers have uncovered the chemical inner-workings of an electrolyte they developed for a new generation of solid oxide fuel cells. To uncover the location of the proton-introduction reaction, the team studied extensively the hydration reaction of their scandium-substituted barium zirconate perovskite through a combination of synchrotron radiation analysis, large-scale simulations, machine learning, and thermogravimetric analysis. The new data has the potential to accelerate the development of more efficient fuel cells.

Surprise effect: Methane cools even as it heats      (via sciencedaily.com) 

Most climate models do not yet account for a recent discovery: methane traps a great deal of heat in Earth's atmosphere, but also creates cooling clouds that offset 30% of the heat.

Giant volcanic 'chain' spills secrets on inner workings of volcanoes      (via sciencedaily.com) 

Volcanic relics scattered throughout the Australian landscape are a map of the northward movement of the continent over a 'hotspot' inside the Earth, during the last 35 million years.

'Rock stars' solve long-standing diamond conundrum      (via sciencedaily.com) 

Two researchers have used a standard laptop computer and a humble piece of rock -- from the 'waste pile' of a diamond mine -- to solve a long-held geological conundrum about how diamonds formed in the deep roots of the earth's ancient continents.

Public acceptance of fossil fuel subsidy removal could be improved in developing countries      (via sciencedaily.com) 

People might be more positive to the removal of fuel subsidies if told where the money would be spent instead. This has been shown in a study which investigated attitudes towards removing fossil fuel subsidies in five developing countries.

Activity deep in Earth affects the global magnetic field      (via sciencedaily.com) 

Compass readings that do not show the direction of true north and interference with the operations of satellites are a few of the problems caused by peculiarities of the Earth's magnetic field. The magnetic field radiates around the world and far into space, but it is set by processes that happen deep within the Earth's core, where temperatures exceed 5,000-degrees C. New research from geophysicists suggests that the way this super-hot core is cooled is key to understanding the causes of the peculiarities -- or anomalies, as scientists call them -- of the Earth's magnetic field.

Rsearchers examine combined effects of two combustion technologies on the emission of coal-fired boilers      (via sciencedaily.com) 

There is currently a large dependence on coal for power generation. As coal-fired plants cause environmental and health hazards, technologies such as swirl flow and air staging have been proposed to mitigate the pollutants in their emissions. However, it is unclear how effective these technologies are in reducing the environmental costs of these plants. Now, researchers have provided insights on this front in a new study, delineating their efficacies with experiments and simulations.

Switching to hydrogen fuel could prolong the methane problem      (via sciencedaily.com) 

Hydrogen is often heralded as the clean fuel of the future, but new research suggests that leaky hydrogen infrastructure could end up increasing atmospheric methane levels, which would cause decades-long climate consequences.

The world's atmospheric rivers now have an intensity ranking like hurricanes      (via sciencedaily.com) 

Atmospheric rivers, which are long, narrow bands of water vapor, are becoming more intense and frequent with climate change. A new study demonstrates that a recently developed scale for atmospheric river intensity (akin to the hurricane scale) can be used to rank atmospheric rivers and identify hotspots of the most intense atmospheric rivers not only along the U.S. West Coast but also worldwide.

Life in the smoke of underwater volcanoes      (via sciencedaily.com) 

Disconnected from the energy of the sun, the permanently ice-covered Arctic deep sea receives miniscule amounts of organic matter that sustains life. Bacteria which can harvest the energy released from submarine hydrothermal sources could thus have an advantage. Scientists found bacteria uniquely adapted to this geo-energy floating in deep-sea waters. They describe the role of these bacteria for biogeochemical cycling in the ocean.

A pool at Yellowstone is a thumping thermometer      (via sciencedaily.com) 

Doublet Pool's regular thumping is more than just an interesting tourist attraction. A new study shows that the interval between episodes of thumping reflects the amount of energy heating the pool at the bottom, as well as in indication of how much heat is being lost through the surface. Doublet Pool, the authors found, is Yellowstone's thumping thermometer.

Gas monitoring at volcanic fields outside Naples, Italy, exposes multiple sources of carbon dioxide emissions      (via sciencedaily.com) 

The Phlegraean volcanic fields just west of Naples, Italy, are among the top eight emitters of volcanic carbon dioxide in the world. Since 2005, the Solfatara crater -- one of many circular depressions in the landscape left by a long history of eruptions --has been emitting increased volumes of gas. Today it emits 4,000-5,000 tons of carbon dioxide each day, equivalent to the emissions from burning ~500,000 gallons of gasoline. Researchers estimate that as much as 20%--40% of the current carbon dioxide emissions are from the dissolution of calcite in the rocks, while 60%--80% is from underground magma.
