Published Novel material supercharges innovation in electrostatic energy storage
(via sciencedaily.com) Original source Scientists have developed artificial heterostructures made of freestanding 2D and 3D membranes that have an energy density up to 19 times higher than commercially available capacitors.
Published Clearing the air: Wind farms more land efficient than previously thought
(via sciencedaily.com) Original source Wind power is a source of energy that is both affordable and renewable. However, decision-makers have been reluctant to invest in wind energy due to a perception that wind farms require a lot of land compared to electric power plants driven by fossil fuels. Research was based on the assessment of the land-use of close to 320 wind farms in the U.S. paints a very different picture.
Published Ice age climate analysis reduces worst-case warming expected from rising CO2
(via sciencedaily.com) Original source A detailed reconstruction of climate during the most recent ice age, when a large swath of North America was covered in ice, provides information on the relationship between CO2 and global temperature. Results show that while most future warming estimates remain unchanged, the absolute worst-case scenario is unlikely.
Published East coast mussel shells are becoming more porous in warming waters
(via sciencedaily.com) Original source Researchers have found that over the last 120 years, the porosity -- or small-scale holes -- in mussel shells along the East Coast of the United States has increased, potentially due to warming waters. The study analyzed modern mussel shells in comparison to specimens in the Museum's historic collection.
Published 38 trillion dollars in damages each year: World economy already committed to income reduction of 19 % due to climate change
(via sciencedaily.com) Original source Even if CO2 emissions were to be drastically cut down starting today, the world economy is already committed to an income reduction of 19% until 2050 due to climate change, a new study finds. These damages are six times larger than the mitigation costs needed to limit global warming to two degrees. Based on empirical data from more than 1,600 regions worldwide over the past 40 years, scientists assessed future impacts of changing climatic conditions on economic growth and their persistence.
Published Paradox of extreme cold events in a warming world
(via sciencedaily.com) Original source The Warm Arctic-Cold Continent (WACC) phenomenon is the puzzling combination of Arctic warming and extreme coldness in specific mid-latitude regions. However, the progression of WACC events remains unclear amidst global warming. Scientists have now predicted a sharp decline in the WACC phenomenon post-2030s, affecting extreme weather events. These findings offer critical insights for communities, scientists, and policymakers to refine climate models and strategies and battle climate change.
Published CO2 worsens wildfires by helping plants grow
(via sciencedaily.com) Original source By fueling the growth of plants that become kindling, carbon dioxide is driving an increase in the severity and frequency of wildfires, according to a new study.
Published Cooler transformers could help electric grid
(via sciencedaily.com) Original source Simulations on the Stampede2 supercomputer of the Texas Advanced Computing Center (TACC) are helping scientists engineer solutions to overheating of grid transformers -- a critical component of the electric grid.
Published Yellowstone Lake ice cover unchanged despite warming climate
(via sciencedaily.com) Original source While most lakes around the world are experiencing shorter durations of ice cover, the length of time that Yellowstone Lake is covered by ice each year has not changed in the past century, possibly due to increased snowfall.
Published Global North energy outsourcing demands more attention
(via sciencedaily.com) Original source Manufacturing nations in the Global North are stockpiling energy and emission problems by outsourcing energy-intensive industrial processes to countries in the Global South.
Published Quantum precision: A new kind of resistor
(via sciencedaily.com) Original source Researchers have developed a method that can improve the performance of quantum resistance standards. It's based on a quantum phenomenon called Quantum Anomalous Hall effect.
Published Pyrite, also known as fool's gold, may contain valuable lithium, a key element for green energy
(via sciencedaily.com) Original source The technology revolution and development of new renewable energy resources is driving demand for lithium to new heights, but it is not a common mineral. Scientists say they have found lithium in an unexpected place; fool's gold, or pyrite, deposits.
Published With inspiration from 'Tetris,' researchers develop a better radiation detector
(via sciencedaily.com) Original source A new detector system based on the game 'Tetris' could enable inexpensive, accurate radiation detectors for monitoring nuclear sites.
Published Food security in developed countries shows resilience to climate change
(via sciencedaily.com) Original source A study has found that market forces have provided good food price stability over the past half century, despite extreme weather conditions.
Published New device gathers, stores electricity in remote settings
(via sciencedaily.com) Original source Wirelessly connected devices perform an expanding array of applications, such as monitoring the condition of machinery and remote sensing in agricultural settings. These applications hold much potential for improving the efficiency, but how do you power these devices where reliable electrical sources are not available? Research points to a possible solution in the form of a novel type of battery.
Published Scientist helps link climate change to Madagascar's megadrought
(via sciencedaily.com) Original source A team reveals a clear link between human-driven climate change and the years-long drought currently gripping southern Madagascar.
Published Research examines tweets during Hurricane María to analyze social media use during disasters
(via sciencedaily.com) Original source Understanding how social media is used during a disaster can help with disaster preparedness and recovery for future events.
Published BESSY II: How pulsed charging enhances the service time of batteries
(via sciencedaily.com) Original source An improved charging protocol might help lithium-ion batteries to last much longer. Charging with a high-frequency pulsed current reduces aging effects, an international team demonstrated.
