Published New methodology reveals health, climate impacts of reducing buildings' energy use
(via sciencedaily.com) Increasing energy efficiency in buildings can save money -- and it can also decrease the carbon emissions and air pollution that lead to climate change and health harms. But the climate and health benefits of reducing buildings' energy consumption are rarely quantified. Now, researchers have developed a new method for calculating the health and climate impacts of these energy savings.
Published Studies highlight new approaches to addressing climate change
(via sciencedaily.com) Original source Failing to achieve climate mitigation goals puts increasing pressure on climate adaptation strategies. In two new studies, researchers address novel approaches to these issues.
Published Bacteria generate electricity from wastewater
(via sciencedaily.com) In a breakthrough for the field of bioelectronics, researchers have enhanced the ability of E. coli bacteria to generate electricity. The innovative approach only offers a sustainable solution for organic waste processing while outperforming previous state-of-the-art technologies, opening new horizons for versatile microbial electricity production.
Published New study highlights feasibility and optimization of ammonia-based power generation for carbon neutrality
(via sciencedaily.com) A research team has evaluated the feasibility of ammonia-based power generation through techno-economic and carbon footprint analyses.
Published New study reveals the power of railroads to buffer coal plants from a carbon emissions tax
(via sciencedaily.com) A new study suggests that railroads are likely to cut transportation prices to prop up coal-fired plants if U.S. climate policies further disadvantage coal in favor of less carbon-intensive energy sources.
Published Scientists develop new method to recover high-purity silicon from expired solar panels for upcycling into lithium-ion batteries
(via sciencedaily.com) Scientists have devised an efficient method of recovering high-purity silicon from expired solar panels to produce lithium-ion batteries that could help meet the increasing global demand to power electric vehicles.
Published Devices offers long-distance, low-power underwater communication
(via sciencedaily.com) A new underwater communication and networking technique can achieve kilometer-scale ranges while consuming about one-millionth the power required by current communication methods.
Published New material offers more durable, sustainable multi-level non-volatile phase change memory
(via sciencedaily.com) Researchers scientists have unlocked a new realm of possibilities for non-volatile phase change memory, a type of electronic memory capable of retaining data even without power. Traditionally, researchers have relied on chalcogenides, materials with reversible electrical properties during transitions between crystalline and amorphous states. But an exciting alternative has emerged in the form of layered nickelates, complex oxide materials composed of nickel ions. These nickelates, with their unique layered structure and thermally reversible switching of room-temperature electrical resistivity, offer superior performance and sustainability potential.
Published Electrifying heavy-duty vehicles could reduce environmental inequalities
(via sciencedaily.com) If the region surrounding Chicago -- North America's largest freight hub -- shifted just 30% of its current on-road heavy-duty vehicles to electric versions, it would substantially reduce pollution and save hundreds of lives per year, with the benefits largely concentrated in disadvantaged communities, according to a new study. The study authors highlight that neighborhoods with predominantly Black, Hispanic and Latinx residents would benefit the most -- potentially reducing disproportionate pollution and health burdens in historically marginalized areas.
Published Scientists develop an energy-efficient wireless power and information transfer system
(via sciencedaily.com) Simultaneous wireless information and power transfer (SWIPT)-aided nonorthogonal multiple access (NOMA) system, used for communication in the Industrial Internet of Things (IIoTs), suffers from significant energy loss with transmission distance. Now, researchers have developed an energy-efficient framework by applying SWIPT-NOMA to a distributed antenna system. This technology is expected to pave the way for more efficient and optimized IoT environments.
Published Blowing snow contributes to Arctic warming
(via sciencedaily.com) Original source Atmospheric scientists have discovered abundant fine sea salt aerosol production from wind-blown snow in the central Arctic, increasing seasonal surface warming.
Published Extreme El Niño weather saw South America's forest carbon sink switch off
(via sciencedaily.com) Original source Tropical forests in South America lose their ability to absorb carbon from the atmosphere when conditions become exceptionally hot and dry, according to new research. For a long time, tropical forests have acted as a carbon sink, taking more carbon out of the air than they release into it, a process that has moderated the impact of climate change. But new research found that in 2015 -- 2016, when an El Niño climate event resulted in drought and the hottest temperatures ever recorded, South American forests were unable to function as a carbon sink.
Published Better cybersecurity with new material
(via sciencedaily.com) Digital information exchange can be safer, cheaper and more environmentally friendly with the help of a new type of random number generator for encryption. The researchers behind the study believe that the new technology paves the way for a new type of quantum communication.
Published A global observatory to monitor Earth's biodiversity
(via sciencedaily.com) Original source At a time of unparalleled rates of biodiversity loss, a new interconnected system to monitor biodiversity around the world is needed to guide action quickly enough to target conservation efforts to where they are most needed.
Published The search for the super potato
(via sciencedaily.com) Original source As climate change continues to pose severe challenges to ensuring sustainable food supplies around the world, scientists are looking for ways to improve the resilience and nutritional quality of potatoes. Scientists have assembled the genome sequences of nearly 300 varieties of potatoes and its wild relatives to develop more nutritious, disease-free, and weather-proof crop. A team has now created a potato super pangenome to identify genetic traits that can help produce the next super spud.
Published Emphasizing the need for energy independence could change the views of climate deniers, study says
(via sciencedaily.com) Original source Emphasising the need for energy independence and environmental stewardship could help to change people’s minds about the climate crisis, a new study says.
Published Unveiling global warming's impact on daily precipitation with deep learning
(via sciencedaily.com) Original source A research team has conclusively demonstrated that global warming stands as primary driver behind the recent increase in heavy rainfall and heatwaves using deep learning convolutional neural network.
Published Can this forest survive? Predicting forest death or recovery after drought
(via sciencedaily.com) Original source New work could help forest managers predict which forests are most at risk from drought and which will survive.
Published Climate extremes hit stressed economies even harder
(via sciencedaily.com) Original source Economies already under stress respond more strongly to weather events like heat waves, river floods and tropical cyclones, a new study shows. A global economic crisis as during the Covid-19 pandemic strongly amplifies the price increases private households experience from the impacts of weather extremes, a team of researchers finds. The price impacts tripled in China, doubled in the United States and increased by a third in the European Union.
Published New 'droplet battery' could pave the way for miniature bio-integrated devices
(via sciencedaily.com) Researchers have developed a miniature battery that could be used to power tiny devices integrated into human tissues. The design uses an ionic gradient across a chain of droplets -- inspired by how electric eels generate electricity. The device was able to regulate the biological activity of human neurons. This could open the way to the development of tiny bio-integrated devices, with a range of applications in biology and medicine.
