Published How pollution may remain in water after oil spill cleanups
(via sciencedaily.com) Original source The way oil drops break up at the water's surface means some oil may not get cleaned up after a spill.
Published Solar farms with stormwater controls mitigate runoff, erosion, study finds
(via sciencedaily.com) Original source As the number of major utility-scale ground solar panel installations grows, concerns about their impacts on natural hydrologic processes also have grown. However, a new study by Penn State researchers suggests that excess runoff or increased erosion can be easily mitigated -- if these 'solar farms' are properly built.
Published Rural belts around cities can reduce urban summer temperatures by up to 0.5°C
(via sciencedaily.com) Original source The key to cooling 'urban heat islands' may lie in the countryside, according to a new study.
Published Microbes found to destroy certain 'forever chemicals'
(via sciencedaily.com) Original source An environmental engineering team has discovered that specific bacterial species can cleave the strong fluorine-to-carbon bond certain kinds of 'forever chemical' water pollutants, offering promise for low-cost treatments of contaminated drinking water.
Published Diatom surprise could rewrite the global carbon cycle
(via sciencedaily.com) Original source When it comes to diatoms that live in the ocean, new research suggests that photosynthesis is not the only strategy for accumulating carbon. Instead, these single-celled plankton are also building biomass by feeding directly on organic carbon in wide swaths of the ocean. These new findings could lead to reduced estimates regarding how much carbon dioxide diatoms pull out of the air via photosynthesis, which in turn, could alter our understanding of the global carbon cycle, which is especially relevant given the changing climate.
Published Aussie innovation spearheads cheaper seafloor test for offshore wind farms
(via sciencedaily.com) Original source Australian engineers have unveiled a clever new device -- based on a modified speargun -- as a cheap and efficient way to test seabed soil when designing offshore wind farms.
Published Powerful new particle accelerator a step closer with muon-marshalling technology
(via sciencedaily.com) Original source New experimental results show particles called muons can be corralled into beams suitable for high-energy collisions, paving the way for new physics.
Published Physicists develop new theory describing the energy landscape formed when quantum particles gather together
(via sciencedaily.com) Original source An international team of physicists has proven new theorems in quantum mechanics that describe the 'energy landscapes' of collections of quantum particles. Their work addresses decades-old questions, opening up new routes to make computer simulation of materials much more accurate. This, in turn, may help scientists design a suite of materials that could revolutionize green technologies.
Published Smart soil can water and feed itself
(via sciencedaily.com) Original source A newly engineered type of soil can capture water out of thin air to keep plants hydrated and manage controlled release of fertilizer for a constant supply of nutrients.
Published Paving the way to extremely fast, compact computer memory
(via sciencedaily.com) Original source Researchers have demonstrated that the layered multiferroic material nickel iodide (NiI2) may be the best candidate yet for devices such as magnetic computer memory that are extremely fast and compact. Specifically, they found that NiI2 has greater magnetoelectric coupling than any known material of its kind.
Published Microplastic pollution increases sea foam height and stability
(via sciencedaily.com) Original source Researchers examine the specific impacts of microplastics on the geophysics of sea foam formation in the critical zone where water meets air in the top layer of the ocean. They devised two simulations for their work -- a column filled with sea water injected with air and a laboratory-scale breaking wave channel to test the impacts of wave height on sea foam in the surface microlayer -- and tested their effects on sea foam formation, stability, and duration.
Published Weather experts discover new effect of storm -- in a teacup
(via sciencedaily.com) Original source A new study reveals that Storm Ciaran cut an invisible path of mayhem across southern Britain last autumn, destroying any possibility that 20 million people could have a proper cup of tea at breakfast. The storm's record-breaking low pressure meant the boiling point of water was below the crucial 100 degrees Celsius required for a decent cuppa.
Published Additional taxes vs. water quotas: Study compares the most effective system to manage water consumption in agriculture
(via sciencedaily.com) Original source A new study finds that the proportional allocation of water, and not additional taxes on the resource, is more effective from the point of view of those engaged in agriculture.
Published Breakthrough in quantum microscopy: Researchers are making electrons visible in slow motion
(via sciencedaily.com) Original source Physicists are developing quantum microscopy which enables them for the first time to record the movement of electrons at the atomic level with both extremely high spatial and temporal resolution. Their method has the potential to enable scientists to develop materials in a much more targeted way than before.
Published Producing hydrogen and fertilizer at the same time
(via sciencedaily.com) Original source This new concept could allow the needs of previously separate industries to be combined: the production of hydrogen and the production of fertilizer.
Published Loss of oxygen in lakes and oceans a major threat to ecosystems, society, and planet
(via sciencedaily.com) Original source Oxygen is a fundamental requirement of life, and the loss of oxygen in water, referred to as aquatic deoxygenation, is a threat to life at all levels. In fact, researchers describe how ongoing deoxygenation presents a major threat to the stability of the planet as a whole.
Published Study examines urban forests across the United States
(via sciencedaily.com) Original source Tree-planting campaigns have been underway in the United States, especially in cities, as part of climate mitigation efforts given the many environmental benefits of urban forests. But a new study finds that some areas within urban forests in the U.S., may be more capable than trees growing around city home lawns in adapting to a warmer climate.
Published High and low tide cause low and high methane fluxes
(via sciencedaily.com) Original source Methane, a strong greenhouse gas that naturally escapes from the bottom of the North Sea, is affected by the pressure of high or low tide. Methane emissions from the seafloor can be just easily three times as much or as little, depending on the tide, according to a new study.
Published Light-induced Meissner effect
(via sciencedaily.com) Original source Researchers have developed a new experiment capable of monitoring the magnetic properties of superconductors at very fast speeds.
Published Scientists call for 'major initiative' to study whether geoengineering should be used on glaciers
(via sciencedaily.com) Original source Scientists have released a landmark report on glacial geoengineering -- an emerging field studying whether technology could halt the melting of glaciers and ice sheets as climate change progresses.
