Published Smoke from Western wildfires can influence Arctic sea ice
(via sciencedaily.com) Sea ice and wildfires may be more interconnected than previously thought, according to new research.
Published For dairy farmers, where does the time go?
(via sciencedaily.com) Globally, dairy producers face increasing challenges regarding sustainability, including declining numbers of workers in the agricultural sector, while continuing to meet increasing demand for nutritious and affordable food. Dairy systems must now focus on more sustainable production that reflects economic, environmental, and social goals. A new report explores labor time-use on Irish pasture-based dairy farms in the busy spring and summer seasons.
Published Just 10 financial actors hold the key to climate change
(via sciencedaily.com) A new report has identified the 10 financial actors with the most influence on the fossil fuel economy and outlines the decisive role they can play in helping de-carbonize our future.
Published Going against the flow: Scientists reveal garden eels' unique way of feeding
(via sciencedaily.com) A new lab study on garden eels shows how these shy creatures use their burrows, and change their movement and posture, when feeding in strong currents.
Published Desert climate overtaking more of Central Asia
(via sciencedaily.com) Rising annual temperatures and dwindling yearly precipitation across the mid-latitudes of Central Asia have extended its desert climate 60 miles northward since the 1980s, says a recent study.
Published All-in-one solar-powered tower makes carbon-neutral jet fuel
(via sciencedaily.com) Researchers have designed a fuel production system that uses water, carbon dioxide (CO2), and sunlight to produce aviation fuel. They have implemented the system in the field, and the design could help the aviation industry become carbon neutral.
Published Arctic shrub expansion limited by seed dispersal and wildfire
(via sciencedaily.com) Scientists investigating the growth of Arctic vegetation have found that seed dispersal and fire will slow its land expansion in the long term, despite more favorable conditions from a warming planet.
Published Fuel cells: Novel multi-proton carrier complex as efficient proton conductor at high temps
(via sciencedaily.com) Fuel cells often fall short when it comes to operating at temperatures beyond 100 degrees Celsius owing to their dependence on water as a proton conduction medium. To overcome this issue, a team of researchers designed a new hydrogen-bonded starburst-shaped metal complex consisting of ruthenium (III) ion and six imidazole-imidazolate groups. The resulting single molecular crystal shows excellent proton conductivity even at temperatures as high as 180°C and as low as --70 °C.
Published Why corals glow even in the depths of the sea
(via sciencedaily.com) A new study reveals that the phenomenon in deep reefs in which corals display glowing colors (fluorescence) is intended to serve as a mechanism for attracting prey. The study shows that the marine animals on which corals prey recognize the fluorescent colors and are attracted to them.
Published Air samples from Arctic region show how fast Earth is warming
(via sciencedaily.com) Researchers report direct observations of size-resolved ice nucleating particles in the central Arctic, spanning the entire sea ice growth and decline cycle. Their results show a strong seasonality of these particles, with lower concentrations in the winter and spring, and enhanced concentrations during summer melt from local biology.
Published Electric vehicles pass the remote road test
(via sciencedaily.com) A new study, which demonstrates that even the most rural areas of Australia are feasible for electric vehicles, provides new hope for how the technology could be spread around the most secluded locations in other parts of the world. The study found the vast majority of residents, or 93 per cent, could travel to essential services with even the lower-range of electric vehicles currently available on the Australian market, without needing to recharge en route.
Published Researchers create method for breaking down plant materials for earth-friendly energy
(via sciencedaily.com) With energy costs rising, and the rapidly emerging effects of burning fossil fuels on the global climate, the need has never been greater for researchers to find paths to products and fuels that are truly renewable.
Published Ozone depletion over North Pole produces weather anomalies
(via sciencedaily.com) Researchers have established that the destruction of ozone over the Arctic in the spring causes abnormal weather throughout the northern hemisphere, with many places being warmer and drier than average -- or too wet.
Published Birdwatching brings millions of dollars to Alaska
(via sciencedaily.com) New research found that nearly 300,000 birders traveled to the state and spent about $378 million in 2016. Birdwatching supported roughly 4,300 jobs in Alaska that year.
Published Arctic temperatures are increasing four times faster than global warming
(via sciencedaily.com) A new analysis of observed temperatures shows the Arctic is heating up more than four times faster than the rate of global warming. The trend has stepped upward steeply twice in the last 50 years, a finding missed by all but four of 39 climate models.
Published Why natural gas is not a bridge technology
(via sciencedaily.com) The expansion of natural gas infrastructure jeopardizes energy transition, as natural gas is not a bridge technology towards a 100 per cent renewable energy system as defined by the Paris Climate Agreement. The researchers have examined the natural gas issue from five perspectives and given gas a fairly poor climate balance, comparable to that of coal or oil. They recommend that politicians and scientists revise the current assumptions about natural gas.
Published Bacteria for blastoff: Using microbes to make supercharged new rocket fuel
(via sciencedaily.com) Biofuel scientists used an oddball molecule made by bacteria to develop a new class of sustainable biofuels powerful enough to launch rockets. The candidate molecules have greater projected energy density than any petroleum product, including the leading aviation and rocket fuels, JetA and RP-1.
Published Thawing permafrost is shaping the global climate
(via sciencedaily.com) How is climate change affecting the permanently frozen soils of the Arctic? What will the consequences be for the global climate, human beings, and ecosystems? And what can be done to stop it?
Published Reaction insights help make sustainable liquid fuels
(via sciencedaily.com) Methanol made from CO2 in the air can be transformed into carbon neutral fuels. A new mechanistic understanding aids development of this sustainable alternative.
Published Genome of voracious desert locust sequenced
(via sciencedaily.com) The first high-quality genome of the desert locust -- those voracious feeders of plague and devastation infamy and the most destructive migratory insect in the world -- has been produced. The genome of the desert locust (Schistocerca gregaria) is enormous at just under 9 billion base pairs, nearly three times the size of the human genome. The size of the desert locust's chromosomes is remarkable; compare them to those of the model fruit fly Drosophila melanogaster, the first insect genome ever assembled. Many of the desert locust's individual chromosomes are larger than the entire fruit fly genome. Next to the fruit fly, it's like an 18-wheeler next to a compact car.
