Iodine accelerates formation of cloud condensation nuclei in the atmosphere
Iodine accelerates formation of cloud condensation nuclei in the atmosphere
International research collaboration shows influence of iodine chemistry on formation of new particles in marine atmosphere and recycling of iodine during particle growth The natural cycling of materials between the biosphere and the atmosphere is of great importance to the Earth's climate system. The best known example is the cycling of carbon between the atmosphere, the land biosphere and the ocean.

Seismic sensing reveals flood damage potential
Seismic sensing reveals flood damage potential
Researchers led by Göttingen University use earthquake sensors to track magnitude and velocity of 2021 summer flood Rapidly evolving floods are a major and growing hazard worldwide. Currently, their onset and evolution is hard to identify using existing systems. However, seismic sensors already in place to detect earthquakes could be a solution to this problem.

Improved air quality accelerates global warming in recent decades
Improved air quality accelerates global warming in recent decades
An international research team led by Leipzig University has used satellite data to demonstrate that concentrations of pollutant particles have decreased significantly since the year 2000. This is necessary due to their impact on health. But it is also of great significance for another reason, since it has reduced the particles- cooling effect on the climate.

New Software Platform Advances Understanding of the Surface Finish of Manufactured Components
New Software Platform Advances Understanding of the Surface Finish of Manufactured Components
Scientists develop platform that combines measurements of surface topography in a digital twin Scientists from the University of Freiburg, Germany, and the University of Pittsburgh have developed a software platform that facilitates and standardizes the analysis of surfaces. The platform enables users to create a digital twin of a surface and thus to help predict, for example, how quickly it wears out, how well it conducts heat, or how well it adheres to other materials.

Enhanced ocean oxygenation during Cenozoic warm periods
Enhanced ocean oxygenation during Cenozoic warm periods
Earth's past warm periods witnessed the shrinkage of the open ocean's oxygen-deficient zones. According to a new study from an international team led by researchers from the Max Planck Institute for Chemistry, the oxygen-deficient zones that occur in the open ocean shrank in long warm periods of the past.

If groundwater sinks, streams and rivers seep away and pollute drinking water
If groundwater sinks, streams and rivers seep away and pollute drinking water
Increasing drought, less precipitation, increased demand for water in agriculture - climate change is taking its toll on our groundwater.

In Search of the Lost City of Natounia
Archaeological investigations offer up new findings on the history of Parthian settlements in Iraqi Kurdistan The mountain fortress of Rabana-Merquly in modern Iraqi Kurdistan was one of the major regional centres of the Parthian Empire, which extended over parts of Iran and Mesopotamia approximately 2,000 years ago.

Life in the earth's interior as productive as in some ocean waters
Life in the earth’s interior as productive as in some ocean waters
Microorganisms in aquifers deep below the earth's surface produce similar amounts of biomass as those in some marine waters. This is the finding of researchers led by the Friedrich Schiller University Jena and the German Centre for Integrative Biodiversity Research (iDiv), both Germany. Applying a unique, ultra-sensitive measurement method using radioactive carbon, they were able to demonstrate for the first time that these biotic communities in absolute darkness do not depend on sunlight.

Lava ejected during the 2021 Cumbre Vieja eruption was unusually fluid
Lava ejected during the 2021 Cumbre Vieja eruption was unusually fluid
Researchers at Mainz University determine that the lava from the recent volcanic eruption on La Palma was particularly low in viscosity 28 June 2022 The Cumbre Vieja eruption in 2021 was the most protracted and disruptive volcanic eruption in the recent history of the Canary Island of La Palma. More than 1,600 structures, including about 1,300 residential buildings, were destroyed or damaged.

Defects in quartz crystal structure reveal the origin of dust
Defects in quartz crystal structure reveal the origin of dust
Global warming and a progressively drier climate in many parts of the world are causing more dust storms. To predict how these storms are caused, researchers are looking into the past to understand where the dust came from, for how long, and over what distances it was transported. An international research team led by Dr. Aditi K. Dave and Professor Kathryn Fitzsimmons from the Department of Geosciences at the University of Tübingen, along with colleagues from Romania, Brazil, Kazakhstan and Tajikistan, have now developed a new method of doing this.

Huge pool of heat in the Pacific caused by climate change
Huge pool of heat in the Pacific caused by climate change
A long-term warm water body that continues to warm has now been discovered by a team from the CLICCS Cluster of Excellence at the University of Hamburg. It is three million square kilometers in size, is due to the human-induced increase in greenhouse gases, and favors extreme heat waves in the Northeast Pacific.

Origins of carbonatite magma revealed
Origins of carbonatite magma revealed
Carbonatite rocks are economically important. The many hundreds of known carbonatite deposits on all continents are important repositories of rare-earth metals such as lanthanum, cerium and neodymium. These are used in many key technologies, including smartphones, plasma and LCD screens, as well as in radiology for medical diagnoses, in generators in wind turbines, and in electric motors.

Carbonatite rocks are economically important: The hundreds of known fossil carbonatite deposits on all continents are important storage sites for rare earth metals such as lanthanum, cerium, and neodymium. They are used in many key technologies, including smartphones, plasma and LCD screens, medical diagnostic radiology, wind turbine generators, and electric motors.

Corals as climate archives
Unusually well-preserved reef corals from the Geological and Palaeontological Collection at Leip-zig University hold a great secret: they allow us to travel far into the past and reconstruct climatic conditions in our latitudes. Researchers from Leipzig University, the Universities of Bremen and Greifswald, and UniLaSalle in Beauvais have now succeeded in doing just this.

Study explores concentrations of microplastics in the Rhine floodplains near Langel in Cologne
Microplastics accumulate in the Rhine meadows at Langel-Merkenich / topography and flooding determine local concentrations of particles in the soil Microplastics can be deposited in river floodplains and transported to deeper soil horizons. Local topography, flood frequency, and soil characteristics are responsible for the amount of plastic particles deposited and their possible transport into deeper soil.

Algae reveal clues about climate changes over millions of years
Göttingen scientists identify and investigate algae which register sea water temperatures of the warmest months Organisms adjust their cell walls according to environmental conditions such as temperature. Some adaptations involve changes in lipids which may still be preserved long after the rest of the organisms has been degraded.

Artificial Intelligence Decodes Causes of Mass Extinction in the Permian
Volcanic eruptions in Siberia caused massive climate change 252 million years ago. Approximately 75 percent of all land organisms and 90 percent of all ocean organisms perished. The paleontologist Dr. William Foster at the Center for Earth System Research and Sustainability (CEN) has now decoded the causes of this mass extinction in the oceans.

No glacial fertilization effect in the Antarctic Ocean
International study led by the University of Bonn records 1.5 million years of climate in the drill core Can iron-rich dust fertilize the ocean, stimulate algae growth there, and thereby capture carbon dioxide from the atmosphere? An international research team led by the University of Bonn used deep-sea sediment cores from the Scotia Sea to investigate whether this hypothetical greenhouse gas sink had an effect during ice ages.
