Published New AI system predicts how to prevent wildfires
(via sciencedaily.com) A machine learning model can evaluate the effectiveness of different management strategies.
Published Smoke from the Black Summer wildfires in Australia impacted the climate and high altitude winds of the southern hemisphere for more than a year and a half
(via sciencedaily.com) The 2019/20 wildfires in Australia transported more smoke into the atmosphere than observed ever before anywhere in the world. In the so-called Black Summer, three times as many particles reached high air layers as in the previous record wildfires in Canada during summer 2017. Research now reveals the climate impact of these huge fires: Smoke particles with a total mass of around one million tonnes spread across the southern hemisphere and affected the climate for about one and a half years by warming the upper atmosphere and cooling the lower atmosphere close to Earth's surface.
Published High-accuracy electric vehicle battery monitoring with diamond quantum sensors for driving range extension
(via sciencedaily.com) The issue of battery usage inefficiency in electric vehicles resulting from an inaccurate battery charge measurement may finally get resolved, thanks to a diamond quantum sensor prototype. The sensor can measure currents in a wide range as well as detect milliampere-level currents in a noisy environment, improving the detection accuracy from 10% to within 1%.
Published Robo-bug: A rechargeable, remote-control cyborg cockroach
(via sciencedaily.com) Researchers have engineered a system for creating remote controlled cyborg cockroaches, equipped with a tiny wireless control module that is powered by a rechargeable battery attached to a solar cell. This achievement will help make the use of cyborg insects a practical reality.
Published The impact of megafires on estuaries from Australia's 'Black Summer'
(via sciencedaily.com) Estuaries are one of the most valuable biomes on Earth, and megafires -- like Australia's 2019/20 Black Summer fires -- represent an emerging threat to estuarine and coastal ecosystems, with the extent and proximity of the wildfire influencing the impact on estuaries.
Published A sustainable battery with a biodegradable electrolyte made from crab shells
(via sciencedaily.com) Accelerating demand for renewable energy and electric vehicles is sparking a high demand for the batteries that store generated energy and power engines. But the batteries behind these sustainability solutions aren't always sustainable themselves. Scientists have now create a zinc battery with a biodegradable electrolyte from an unexpected source -- crab shells.
Published A new concept for low-cost batteries
(via sciencedaily.com) Original source Engineers have designed a battery made from inexpensive, abundant materials, that could provide low-cost backup storage for renewable energy sources. Less expensive than lithium-ion battery technology, the new architecture uses aluminum and sulfur as its two electrode materials with a molten salt electrolyte in between.
Published New stable quantum batteries can reliably store energy into electromagnetic fields
(via sciencedaily.com) Original source Researchers have proposed that the micromasers can serve as excellent model for future quantum batteries.
Published Wildfire experts provide guidance for new research directions
(via sciencedaily.com) A new paper by dozens of wildfire experts across the nation highlights the need for a more strategic and interdisciplinary approach to pursuing wildfire research and protecting vulnerable communities.
Published Dry lightning sparks some of the most destructive and costly wildfires in California
(via sciencedaily.com) Researchers have developed the first long-term climatology of dry lightning -- lightning which occurs with less than 2.5mm of rainfall -- in central and northern California.
Published Air pollution, including during wildfires, shows ill effects in children
(via sciencedaily.com) New research linking air pollution data from federal monitors in the Sacramento area of California, including during significant fires, is showing ill effects of pollution exposure among children, a new study suggests.
Published Wildfires disproportionately affect the poor
(via sciencedaily.com) With fires raging from California to Alaska, the 2022 wildfire season is off to a violent start. It's an ominous sign of what promises to be another record-breaking fire season in the U.S. Roughly 2 million acres burned last month. And major fires are currently scorching Idaho, Utah and California, threatening tens of thousands of Americans' homes and livelihoods. Many of those at risk are lower-income Americans who face canceled homeowners insurance policies and rising premiums, according to new research.
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 Western U.S. wildfire smoke plumes are getting taller, researchers find
(via sciencedaily.com) In recent years the plumes of smoke crawling upward from Western wildfires have trended taller, with more smoke and aerosols lofted up where they can spread farther and impact air quality over a wider area. The likely cause is climate change, with decreased precipitation and increased aridity in the Western U.S. that intensifies wildfire activity.
Published New model developed to predict landslides along wildfire burn scars
(via sciencedaily.com) Researchers have augmented a physics-based numerical model to investigate and predict areas susceptible to debris flows. This augmented model eventually could be used in an early warning system for people living in high-risk areas, enabling them to evacuate before it's too late. Information from model simulations also could be used to design new infrastructure -- such as diversion bars that deflect fast-moving water away from homes and roads -- for high hazard zones.
Published New methodology helps predict soil recovery after wildfires
(via sciencedaily.com) A team of investigators devised a new methodology to enable predictions of how plant growth and water quality would change in the wake of wildfires.
Published Wildfire-smoke observations fill gap in estimating soot's role in climate change
(via sciencedaily.com) New research refining the amount of sunlight absorbed by black carbon in smoke from wildfires will help clear up a long-time weak spot in earth system models, enabling more accurate forecasting of global climate change.
Published Cats injured in wildfires at risk of deadly blood clots
(via sciencedaily.com) Cats injured in California wildfires are at risk of forming deadly blood clots, according to new research.
Published California's trees are dying, and might not be coming back
(via sciencedaily.com) The State of California is banking on its forests to help reduce planet-warming carbon dioxide in the atmosphere. But that element of the state's climate-change solution arsenal may be in jeopardy, as new research reports that trees in California's mountain ranges and open spaces are dying from wildfires and other pressures -- and fewer new trees are filling the void.
Published California's Dixie Fire shows impact of legacy effects, prescribed burns
(via sciencedaily.com) The 2021 Dixie Fire burned over nearly 1 million acres in California and cost $637 million to suppress, making it the largest and most expensive wildfire to contain in state history. Fire history largely determined how severely the wildfire burned, and low-severity fire treatments had the largest impact on reducing the worst effects of the fire, according to a research team.
