Published A new weapon in the war on robocall scams
(via sciencedaily.com) The latest weapon in the war on robocalls is an automated system that analyzes the content of unsolicited bulk calls to shed light on both the scope of the problem and the type of scams being perpetuated by robocalls. The tool, called SnorCall, is designed to help regulators, phone carriers and other stakeholders better understand and monitor robocall trends -- and take action against related criminal activity.
Published An early warning system for joint heat and ozone extremes in China
(via sciencedaily.com) Original source Scientists have identified large-scale climate patterns that could be used to predict the co-occurrence of extreme heat and ozone days in China months before they occur. Like predictions for hurricane and wildfire seasons, the forecasts could help the government prepare resources and implement policies to mitigate the severity of the season.
Published Classroom environmental education doesn't change attitudes
(via sciencedaily.com) Original source Researchers evaluated the effectiveness of conservation educational activities in the Cape Verde Island of Maio.
Published Marine protected areas overwhelmingly manage with climate change in mind
(via sciencedaily.com) Original source Scientific findings don't always translate neatly into actions, especially in conservation and resource management. The disconnect can leave academics and practitioners disheartened and a bit frustrated.
Published Nitrogen runoff strategies complicated by climate change
(via sciencedaily.com) Original source As climate change progresses, rising temperatures may impact nitrogen runoff from land to lakes and streams more than projected increases in total and extreme precipitation for most of the continental United States, according to new research from a team of climate scientists.
Published New Antarctic extremes 'virtually certain' as world warms
(via sciencedaily.com) Original source Extreme events in Antarctica such as ocean heatwaves and ice loss will almost certainly become more common and more severe, researchers say.
Published Smart devices: Putting a premium on peace of mind
(via sciencedaily.com) The White House has announced plans to roll out voluntary labeling for internet-connected devices like thermostats and baby monitors that meet certain cybersecurity standards. A new survey of U.S. consumers shows that they are willing to pay a significant premium to tell which gadgets are safe from security attacks before they buy. But voluntary product labels may not be enough if the program is going to protect consumers in the long run, the findings suggest.
Published Wildfires emit potent climate-warming organic particles
(via sciencedaily.com) Original source Researchers found that wildfires are causing a much greater warming effect than has been accounted for by climate scientists. The work, which focuses on the role of 'dark brown carbon' -- an abundant but previously unknown class of particles emitted as part of wildfire smoke -- highlights an urgent need to revise climate models and update approaches for the changing environment.
Published Sustainable plastic made more compostable
(via sciencedaily.com) Original source Researchers have developed a way to make a promising, sustainable alternative to petroleum-based plastics more biodegradable. A team has made a bio-based polymer blend that's compostable in both home and industrial settings.
Published Geomagnetic field protects Earth from electron showers
(via sciencedaily.com) Original source Geophysicists studied the activity of high energy electrons and clarified the unexpected protective role of the geomagnetic field surrounding the Earth.
Published Hartshorn salt and 'baking' solves a serious environmental problem
(via sciencedaily.com) Original source Polyester is the second most used textile in the world and an environmental menace, especially because most of it never gets recycled. The fabric, a blend of plastic and cotton, has been difficult for the industry to separate and therefore recycle. Now, a group of young chemists has invented a green and surprisingly simple solution using a single household ingredient.
Published Invasion of the Arctic Ocean by Atlantic plankton species reveals a seasonally ice-free ocean during the last interglacial
(via sciencedaily.com) Original source A subpolar species associated with Atlantic water expanded far into the Arctic Ocean during the Last Interglacial, analysis of microfossil content of sediment cores reveals. This implies that summers in the Arctic were ice free during this period.
Published Outdoor air pollution may increase non-lung cancer risk in older adults [CORRECTED]
(via sciencedaily.com) Original source Chronic exposure to fine particulate air pollutants (PM2.5) and nitrogen dioxide (NO2) may increase non-lung cancer risk in older adults, according to new research. In a cohort study of millions of Medicare beneficiaries, the researchers found that exposures to PM2.5 and NO2 over a 10-year period increased the risk of developing colorectal and prostate cancers. The researchers also found that even low levels of air pollution exposure may make people particularly susceptible to developing these cancers, in addition to breast and endometrial cancers.
Published Study examines Earth and Mars to determine how climate change affects the paths of rivers
(via sciencedaily.com) Original source The study investigated why the paths of meandering rivers change over time and is a step toward understanding what the hydroclimate on Mars was like when there was still surface water.
Published Mussel-inspired membrane can boost sustainability and add value to industrial wastewater treatment
(via sciencedaily.com) Engineers have developed a new kind of membrane that separates chemicals within wastewater so effectively that they can be reused, presenting a new opportunity for industries to improve sustainability, while extracting valuable by-products and chemicals from wastewater.
Published New photocatalytic system converts carbon dioxide to valuable fuel more efficiently than natural photosynthesis
(via sciencedaily.com) A research team recently developed a stable artificial photocatalytic system that is more efficient than natural photosynthesis. The new system mimics a natural chloroplast to convert carbon dioxide in water into methane, a valuable fuel, very efficiently using light. This is a promising discovery, which could contribute to the goal of carbon neutrality.
Published Sustainable mobility planning supported by doughnut thinking
(via sciencedaily.com) Original source A new scientific article shows how the donut model, which examines the overall sustainability of societies, can be applied to transport.
Published The history and future of ancient einkorn wheat Is written in its genes
(via sciencedaily.com) Original source Researchers have sequenced the complete genome for einkorn wheat, the world's first domesticated crop and traced its evolutionary history. The information will help researchers identify genetic traits like tolerance to diseases, drought and heat, and re-introduce those traits to modern bread wheat.
Published Early-life lead exposure linked to higher risk of criminal behavior in adulthood, researchers find
(via sciencedaily.com) Original source An evaluation of 17 previously published studies suggests that exposure to lead in the womb or in childhood is associated with an increased risk of engaging in criminal behavior in adulthood -- but more evidence is needed to strengthen understanding.
Published Closure of Pittsburgh coal-processing plant tied to local health gains
(via sciencedaily.com) Original source The closure in January 2016 of one of Pittsburgh's biggest coal-processing plants led to immediate and lasting declines in emissions of fossil fuel-related air pollutants. These in turn were linked to near-instant decreases in local heart-related emergency department visits and hospitalizations for cardiovascular diseases, a new study shows. The impact of the closure persisted through at least December 2018, the last month for which data were analyzed.
