Published Microplastics from natural fertilizers are blowing in the wind more often than once thought
(via sciencedaily.com) Original source Though natural fertilizers made from treated sewage sludge are used to reintroduce nutrients onto agricultural fields, they bring along microplastic pollutants too. And according to a small-scale study, more plastic particles get picked up by the wind than once thought. Researchers have discovered that the microplastics are released from fields more easily than similarly sized dust particles, becoming airborne from even a slight breeze.
Published New AI makes better permafrost maps
(via sciencedaily.com) Original source New insights from artificial intelligence about permafrost coverage in the Arctic may soon give policy makers and land managers the high-resolution view they need to predict climate-change-driven threats to infrastructure such as oil pipelines, roads and national security facilities.
Published Artificial 'power plants' harness energy from wind and rain
(via sciencedaily.com) Original source Fake plants are moving into the 21st century! Researchers developed literal 'power plants' -- tiny, leaf-shaped generators that create electricity from a blowing breeze or falling raindrops. The team tested the energy harvesters by incorporating them into artificial plants.
Published Space solar power project ends first in-space mission with successes and lessons
(via sciencedaily.com) Original source A 10-month mission demonstrated three elements of the plan to beam solar power from space to Earth.
Published New technology for conducting deep-sea research on fragile organisms
(via sciencedaily.com) Original source Scientists have successfully demonstrated new technologies that can obtain preserved tissue and high-resolution 3D images within minutes of encountering some of the most fragile animals in the deep ocean.
Published Climate change threatens global forest carbon sequestration, study finds
(via sciencedaily.com) Original source Climate change is causing Western U.S. forests to be less effective carbon sinks, even as it boosts the productivity of forests in the Eastern U.S., according to new research.
Published Discovery changes understanding of water's history on the Moon
(via sciencedaily.com) Original source New research shows the early lunar crust which makes up the surface of the Moon was considerably enriched in water more than 4 billion years ago, counter to previously held understanding.
Published Chasing the light: Study finds new clues about warming in the Arctic
(via sciencedaily.com) Original source The Arctic, Earth's icy crown, is experiencing a climate crisis like no other. It's heating up at a furious pace -- four times faster than the rest of our planet. Researchers are pulling back the curtain on the reduction of sunlight reflectivity, or albedo, which is supercharging the Arctic's warming.
Published Research sheds new light on Moon rock formation solving major puzzle in lunar geology
(via sciencedaily.com) Original source New research has cracked a vital process in the creation of a unique rock type from the Moon. The discovery explains its signature composition and very presence on the lunar surface at all, unraveling a mystery which has long-eluded scientists.
Published Earth-sized planet discovered in 'our solar backyard'
(via sciencedaily.com) Original source Astronomers have discovered a planet closer and younger than any other Earth-sized world yet identified. It's a remarkably hot world whose proximity to our own planet and to a star like our sun mark it as a unique opportunity to study how planets evolve.
Published NASA analysis confirms 2023 as warmest year on record
(via sciencedaily.com) Original source Earth's average surface temperature in 2023 was the warmest on record, according to an analysis by NASA. Global temperatures last year were around 2.1 degrees Fahrenheit (1.2 degrees Celsius) above the average for NASA's baseline period (1951-1980), scientists from NASA's Goddard Institute for Space Studies (GISS) in New York reported.
Published How tidal range electricity generation can protect coastal areas from flooding
(via sciencedaily.com) Original source Tidal range schemes can protect estuaries and coastal areas from the effects of sea level rise, according to researchers who say that tidal range schemes are vital to protect habitats, housing and businesses from a rising sea level estimated to be over one metre within 80 years. High tides can be limited to existing levels simply by closing sluices and turbines and existing low tide levels can be maintained by pumping. Development of estuarine barrages has been hampered by misconceptions about their operation and fears of disturbance of the ecologically sensitive intertidal areas.
Published Scientists uncover ocean's intricate web of microbial interactions across depths
(via sciencedaily.com) Original source An international team of scientists has uncovered the ocean's intricate web of microbial interactions across depths. Their research provides crucial insights into the functioning of ocean ecosystems.
Published More aerosol particles than thought are forming over Siberia, study finds
(via sciencedaily.com) Original source A new study finds that, contrary to previous beliefs, large amounts of aerosol particles can form over vast areas of the West Siberian taiga in the spring. When temperatures rise, this can have a significant impact on the climate.
Published Wastewater surveillance is key tool in keeping schools open during public health emergencies, study reveals
(via sciencedaily.com) Original source Wastewater surveillance is a potent tool in understanding COVID-19 transmission within school settings and keeping schools open when COVID cases spike, according to a new study.
Published Using idle trucks to power the grid with clean energy
(via sciencedaily.com) Original source Researchers are tapping into idled electric vehicles to act as mobile generators and help power overworked and aging electricity grids. After analyzing energy demand on Alberta's power grid during rush hour, the research proposes an innovative way to replenish electrical grids with power generated from fuel cells in trucks.
Published Reflective materials and irrigated trees: Study shows how to cool one of the world's hottest cities by 4.5°C
(via sciencedaily.com) Original source A combination of cooling technologies and techniques could reduce the temperature and energy needs of Riyadh, Saudi Arabia.
Published Capturing greenhouse gases with the help of light
(via sciencedaily.com) Original source Researchers use light-reactive molecules to influence the acidity of a liquid and thereby capture of carbon dioxide. They have developed a special mixture of different solvents to ensure that the light-reactive molecules remain stable over a long period of time. Conventional carbon capture technologies are driven by temperature or pressure differences and require a lot of energy. This is no longer necessary with the new light-based process.
Published Study uncovers potential origins of life in ancient hot springs
(via sciencedaily.com) Original source A research team investigated how the emergence of the first living systems from inert geological materials happened on the Earth, more than 3.5 billion years ago. Scientists found that by mixing hydrogen, bicarbonate, and iron-rich magnetite under conditions mimicking relatively mild hydrothermal vent results in the formation of a spectrum of organic molecules, most notably including fatty acids stretching up to 18 carbon atoms in length.
Published Our surprising magnetic galaxy
(via sciencedaily.com) Original source A team of astronomers has created the first-ever map of magnetic field structures within a spiral arm of our Milky Way galaxy. Previous studies on galactic magnetic fields only gave a very general picture, but the new study reveals that magnetic fields in the spiral arms of our galaxy break away from this general picture significantly and are tilted away from the galactic average by a high degree. The findings suggest magnetic fields strongly impact star-forming regions which means they played a part in the creation of our own solar system.
