Published New faster charging hydrogen fuel cell developed


A new design for solid-state hydrogen storage could significantly reduce charging times.
Published A new method boosts wind farms' energy output, without new equipment


Engineers have developed a method to increase wind farms' energy output. Whereas individual turbines are typically controlled separately, the new approach models the wind flow of the entire collection of turbines and optimizes the control of individual units.
Published Tweaking turbine angles squeezes more power out of wind farms


New algorithm forces turbines in wind farms to be team players, boosting energy output overall.
Published Local renewable energy employment can fully replace U.S. coal jobs nationwide, study finds


Across the United States, local wind and solar jobs can fully replace the coal-plant jobs that will be lost as the nation's power-generation system moves away from fossil fuels in the coming decades, according to a new study.
Published Understanding how rechargeable aqueous zinc batteries work


While scientists have hoped that rechargeable zinc-manganese dioxide batteries could be developed into a viable alternative for grid storage applications, engineers have now identified the atomistic mechanism of charge and discharge in such batteries.
Published New wind sensor uses smart materials to improve drone performance


Engineers have designed and successfully tested a more efficient wind sensor for use on drones, balloons and other autonomous aircraft.
Published Taking your time makes a difference


Researchers find that stem cells in the developing brain of modern humans take longer to divide and make fewer errors when distributing their chromosomes to their daughter cells, compared to those of Neanderthals.
Published High-status Danish Vikings wore exotic beaver furs


Beaver fur was a symbol of wealth and an important trade item in 10th Century Denmark, according to a new study.
Published Just 10 financial actors hold the key to climate change


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 All-in-one solar-powered tower makes carbon-neutral jet fuel


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 Ultrasonic detectors reveal the detrimental effect of wind turbines at forest sites on bats


As more and more wind turbines (WTs) are installed in the course of the energy transition and distance regulations to human settlements are tightened, suitable locations are becoming increasingly difficult to find. As a result, wind turbines are increasingly being erected in forests -- to the detriment of forest specialists among bats.
Published Fuel cells: Novel multi-proton carrier complex as efficient proton conductor at high temps


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 DNA from ancient population in Southern China suggests Native Americans' East Asian roots


For the first time, researchers successfully sequenced the genome of ancient human fossils from the Late Pleistocene in southern China. The data suggests that the mysterious hominin belonged to an extinct maternal branch of modern humans that might have contributed to the origin of Native Americans.
Published Solar-powered chemistry uses carbon dioxide and water to make feedstock for fuels, chemicals


Solar-powered synthesis gas could recycle carbon dioxide into fuels and useful chemicals, an international team of researchers has shown.
Published Caught in the act: Key chemical intermediates in pollutant-to-fuel reaction identified


Researchers identified chemical intermediates in the hydrogenation of copper-adsorbed formate. Depending on the temperature, some of the hydrogenation product decomposed into formaldehyde. The activation energy was also quantified, based on experimental and computational work. These results will be useful for optimizing production of methanol fuel from carbon dioxide.
Published New genetic research on remote Pacific islands yields surprising findings on world's earliest seafarers


New genetic research from remote islands in the Pacific offers fresh insights into the ancestry and culture of the world's earliest seafarers, including family structure, social customs, and the ancestral populations of the people living there today.
Published The heat is on: Traces of fire uncovered dating back at least 800,000 years



Scientists reveal an advanced, innovative method that they have developed and used to detect nonvisual traces of fire dating back at least 800,000 years -- one of the earliest known pieces of evidence for the use of fire. The newly developed technique may provide a push toward a more scientific, data-driven type of archaeology, but -- perhaps more importantly -- it could help us better understand the origins of the human story, our most basic traditions and our experimental and innovative nature.
Published Developmental dyslexia essential to human adaptive success



Researchers say people with developmental dyslexia have specific strengths relating to exploring the unknown that have contributed to the successful adaptation and survival of our species.
Published Offshore wind farms expected to reduce clam fishery revenue, study finds


An important East Coast shellfish industry is projected to suffer revenue losses as offshore wind energy develops along the U.S. Northeast and Mid-Atlantic coasts, according to two recent studies.
Published Modern wind turbines can more than compensate for decline in global wind resource


Wind energy contributes significantly to the energy sector's sustainable, low-CO2 transformation. However, the efficiency of wind turbines depends on available wind resources and the technical characteristics of the turbines.
