Published Measuring electrical conductivity in microorganisms, approaching understanding of microbial ecosystems
(via sciencedaily.com) Original source Researchers have developed an innovative methodology for measuring the electrical conductivity of microbial communities. This methodology holds promise for the development of batteries and electrochemical sensors using microorganisms and may serve as a pivotal tool in elucidating the role of electricity within microbial ecosystems.
Published Lake ecosystems: Nitrogen has been underestimated
(via sciencedaily.com) Original source An ecological imbalance in a lake can usually be attributed to increased nutrient inputs. The result: increased phytoplankton growth, oxygen deficiency, toxic cyanobacterial blooms and fish kills. Until now, controls in lake management have focused primarily on phosphorus inputs to counteract this effect. Now, this dogma is shaken by a study showing that nitrogen is also a critical driver for phytoplankton growth in lakes worldwide.
Published Study reveals accelerated soil priming under climate warming
(via sciencedaily.com) Original source A new study highlights a crucial biosphere feedback mechanism and its effects on releasing soil carbon into the atmosphere.
Published Study finds drought fuels invasive species after wildfires
(via sciencedaily.com) Original source Scientists uncover the intricate dance between drought, wildfires and invasive species in Southern California's coastal sage scrub ecosystems.
Published Creepy crawlies protect apples when flowers are planted on farms
(via sciencedaily.com) Original source Bugs including hoverflies, lacewings and ladybirds play an important role in keeping Britain's apples healthy, a new study has shown.
Published Researchers look at environmental impacts of AI tools
(via sciencedaily.com) Original source As artificial intelligence (AI) is increasingly used in radiology, researchers caution that it's essential to consider the environmental impact of AI tools.
Published Low-Temperature Plasma used to remove E. coli from hydroponically grown crops
(via sciencedaily.com) Original source In a new study, a team sterilized a hydroponic nutrient solution using low-temperature plasma generated from electricity and the oxygen in the atmosphere. This new sterilization technique may allow farmers to grow crops without the use of chemical pesticides, representing an important advance in agricultural technology for sustainable crop production.
Published Extinctions could result as fish change foraging behavior in response to rising temperatures
(via sciencedaily.com) Original source Fish species respond to temperature increases by going after more readily available prey. Models suggest this behavior could lead to more extinctions.
Published Researchers use Hawk supercomputer and lean into imperfection to improve solar cell efficiency
(via sciencedaily.com) Original source Solar energy is one of the most promising, widely adopted renewable energy sources, but the solar cells that convert light into electricity remains a challenge. Scientists have turned to the High-Performance Computing Center Stuttgart to understand how strategically designing imperfections in the system could lead to more efficient energy conversion.
Published What will it take for China to reach carbon neutrality by 2060?
(via sciencedaily.com) Original source To become carbon neutral by 2060, China will have to build eight to 10 times more wind and solar power installations than existed in 2022, according to a new study. Reaching carbon neutrality will also require major construction of transmission lines.
Published New world record for CIGS solar cells
(via sciencedaily.com) Original source A new record for electrical energy generation from CIGS solar cells has been reached. Scientists have achieved a 23.64 percent efficiency.
Published Researchers harness 2D magnetic materials for energy-efficient computing
(via sciencedaily.com) Original source Researchers used ultrathin van der Waals materials to create an electron magnet that can be switched at room temperature. This type of magnet could be used to build magnetic processors or memories that would consume far less energy than traditional devices made from silicon.
Published Side effects of wide scale forestation could reduce carbon removal benefits by up to a third
(via sciencedaily.com) Original source The side effects of large-scale forestation initiatives could reduce the CO2 removal benefits by up to a third, a pioneering study has found.
Published Stronger storms free more nutrients from mud flats
(via sciencedaily.com) Original source If storms become stronger in the future due to climate change, more nitrogen may be released from the bottom of coastal seas.
Published Method identified to double computer processing speeds
(via sciencedaily.com) Original source Scientists introduce what they call 'simultaneous and heterogeneous multithreading' or SHMT. This system doubles computer processing speeds with existing hardware by simultaneously using graphics processing units (GPUs), hardware accelerators for artificial intelligence (AI) and machine learning (ML), or digital signal processing units to process information.
Published Converting rainforest to plantation impacts food webs and biodiversity
(via sciencedaily.com) Original source Every day, new areas of rainforests are converted into plantations, drastically changing tropical biodiversity and the way the ecosystem functions. Yet, the current understanding of the consequences is fragmentary: previous studies tended to examine either biodiversity or the ecosystem. An international research team brings these threads together in this study. They analyzed organisms ranging from microscopic mites and earthworms in the soil, to beetles and birds in tree canopies, comparing tropical rainforest with rubber and oil palm plantations in Sumatra, Indonesia.
Published New water batteries stay cool under pressure
(via sciencedaily.com) Original source A global team of researchers has invented recyclable 'water batteries' that won't catch fire or explode. The team use water to replace organic electrolytes -- which enable the flow of electric current between the positive and negative terminals -- meaning their batteries can't start a fire or blow up -- unlike their lithium-ion counterparts.
Published 'The future is fungal': New research finds that fungi that live in healthy plants are sensitive to climate change
(via sciencedaily.com) Original source Findings more than a decade in the making reveal a rich diversity of beneficial fungi living in boreal forest trees, with implications for the health of forests.
Published Giant new snake species identified in the Amazon
(via sciencedaily.com) Original source A team of scientists on location with a film crew in the remote Amazon has uncovered a previously undocumented species of giant anaconda.
Published Physicists develop more efficient solar cell
(via sciencedaily.com) Original source Physicists have used complex computer simulations to develop a new design for significantly more efficient solar cells than previously available. A thin layer of organic material, known as tetracene, is responsible for the increase in efficiency.
