Sulfur enhances carbon storage in the Black Sea

(University of Oldenburg ) The depths of the Black Sea store comparatively large amounts of organic carbon. A research team led by scientists from the University of Oldenburg, Germany, has now presented a new hypothesis as to why organic compounds accumulate in this semi-enclosed sea and other oxygen-depleted waters. Reactions with hydrogen sulfide play an important role in stabilizing carbon compounds, the researchers posit in the scientific journal Science Advances. This negative feedback in the climate system could counteract global warming over geological periods.

New research finds 1M deaths in 2017 attributable to fossil fuel combustion

(Washington University in St. Louis) An international team of researchers, including faculty in the McKelvey School of Engineering, has determined what sources contribute to pollution and the health effects they have on global, regional and smaller scales.

Lazy, hazy days no more: A call-to-action to better understand air pollution mechanisms

(Institute of Atmospheric Physics, Chinese Academy of Sciences) A special issue of Advances in Atmospheric Sciences summarizes current work on atmospheric oxidation capacity and advocates further investigations.

World-first discovery could fuel the new green ammonia economy

(Monash University) Monash University scientists have developed a new technique using phosphonium salts that can help drive the future production of green ammonia. This process could reduce the impact of ammonia production on global carbon emissions. Each metric tonne of ammonia produced today contributes to roughly 1.9 metric tonnes of greenhouse emissions.

Four collaborative research centres at Goethe University receiving funding

(Goethe University Frankfurt) Collaborative Research Centres at Goethe University will receive DFG funding: CRC Transregio 326 “Geometry and arithmetic of uniformized structures” (spokesperson: Goethe University, € 9.2 million); CRC 1039 “Signalling by fatty acid derivatives and sphingolipids in health and disease” (spokesperson Goethe University, € 9.6 million); TRR 211 “Strongly interacting matter under extreme conditions” (spokesperson: TU Darmstadt, € 9.2 million); TRR 301 “The tropopause region in a changing atmosphere” (spokesperson: Johannes Gutenberg University Mainz, €12.3 million)

Declining growth rates of global coral reef ecosystems

(Southern Cross University) If the trend of declining coral growth continues at the current rate, the world’s coral reefs may cease calcifying around 2054, a new Southern Cross University study has found.Drawing on research from the late 1960s until now, the paper published in Communications & Environment reveals the global spatiotemporal trends and drivers of coral reef ecosystem growth (known as calcification). 116 studies from 53 published papers were analyzed.

Dinosaurs lived in greenhouse climate with hot summers

(Vrije Universiteit Brussel) Paleoclimatologist Niels de Winter and colleagues developed an innovative way to use the clumped isotope method to reconstruct climate in the geological past on the seasonal scale. They show that dinosaurs had to deal with hotter summers than previously thought. The results suggest that in the mid latitudes, seasonal temperatures will likely rise along with climate warming, while seasonal difference is maintained. This results in very high summer temperatures.

Soil microbes metabolize the same polyphenols found in chocolate, wine

(Colorado State University) A research team led by Kelly Wrighton, associate professor in the College of Agricultural Sciences’ Department of Soil and Crop Sciences, has uncovered new insights into the role of polyphenols in the soil microbiome, known as a black box for its complexity. They proffer an updated theory that soils – much like the human gut – can be food sources for the microbes that live there.

Absorbent aerogels show some muscle

(Rice University) A simple chemical process developed at Rice University creates light and highly absorbent aerogels for environmental remediation or as membranes for batteries and other applications.
