Food quality matters for southern resident killer whales      (via sciencedaily.com) 

Not all Chinook salmon are created equal, and this has a major impact on the energetics for southern resident killer whales. A recent study quantified the lipid content in Fraser River Chinook salmon -- the southern resident's preferred meal -- and found that spring-run Chinook salmon, the earliest to arrive to the Salish Sea are lipid-rich and energy dense; a critical factor for the killer whales who prey on them. Fraser River Chinook salmon that come later in the season have lower energy density.

Risk of population disruption as a result of decarbonization      (via sciencedaily.com) 

Researchers analyzed the effects of decarbonization strategies by linking global resource inventories with demographic systems to generate a matrix showing the risks and benefits. The research suggests that increased demand for energy transition metals (ETMs) could be more disruptive to some communities than winding back production of thermal coal. The team calculated that while a complete phase-out of coal could disrupt mine-town systems with a minimum of 33.5 million people, an additional 115.7 million would be at risk from disruption by ETMs.

Health benefits of using wind energy instead of fossil fuels      (via sciencedaily.com) 

A new study finds that the health benefits associated with wind power could more than quadruple if operators turned down output from the most polluting fossil-fuel-based power plants when energy from wind is available. However, compared to wealthier communities, disadvantaged communities would reap a smaller share of these benefits.

Full decarbonization of U.S. aviation sector is within grasp      (via sciencedaily.com) 

New research shows a pathway toward full decarbonization of U.S. aviation fuel use by substituting conventional jet fuel with sustainably produced biofuels. The study found that planting the grass miscanthus on 23.2 million hectares of existing marginal agricultural lands -- land that often lays fallow or is poor in soil quality -- across the United States would provide enough biomass feedstock to meet the liquid fuel demands of the U.S. aviation sector fully from biofuels, an amount expected to reach 30 billion gallons/year by 2040.

Mimicking life: Breakthrough in non-living materials      (via sciencedaily.com) 

Researchers have discovered a new process that uses fuel to control non-living materials, similar to what living cells do. The reaction cycle can easily be applied to a wide range of materials and its rate can be controlled -- a breakthrough in the emerging field of such reactions. The discovery is a step towards soft robotics; soft machines that can sense what is happening in their environment and respond accordingly.

Automated system to detect compressed air leaks on trains      (via sciencedaily.com) 

Researchers have developed a proof-of-concept system to autonomously detect compressed air leaks on trains and relay the location of the leaks to mechanical personnel for repair. The automated system could reduce the time, costs and labor needed to find and repair air leaks, and it could lower the locomotive industry's overall fuel consumption and exhaust emissions.

Revolutionary technique to generate hydrogen more efficiently from water      (via sciencedaily.com) 

Researchers have made a serendipitous scientific discovery that could potentially revolutionize the way water is broken down to release hydrogen gas -- an element crucial to many industrial processes. The team found that light can trigger a new mechanism in a catalytic material used extensively in water electrolysis, where water is broken down into hydrogen and oxygen. The result is a more energy-efficient method of obtaining hydrogen.

Game changers in fighting climate change: Refuels are suitable for everyday use      (via sciencedaily.com) 

Synthetic fuels produced from renewable sources, so-called refuels, are deemed potential game changers in fighting climate change. Refuels promise to reduce CO2 emissions by up to 90% compared to conventional fuels and they allow for the continued use of existing vehicle fleets with combustion engines and of the refueling infrastructure, from fuel production to transport to sales. Researchers carried out extensive fleet tests in a large-scale project with industry partners and proved that refuels can be used in all vehicles and produced in large quantities in the foreseeable future.
