Rocks undergo changes over millions of years. Yet it is possible to extract information from them about the climate at the time of their formation. Fluids circulating underground change rocks over the course of time. These processes must be taken into account if they are to be used as a climate archive.

International research team led by scientist from Freie Universität Berlin proposes that elevated levels of antibiotic resistance genes be considered a new factor of global change Human-caused global change is a complex phenomenon comprising many factors such as climate change, environmental contamination with chemicals, microplastics, light pollution, and invasive plants.

For the first time, the recovery of unique geological samples combined with sophisticated modelling provides surprising insights into when and where today's Antarctic ice sheet formed. In recent years global warming has left its mark on the Antarctic ice sheets. The "eternal" ice in Antarctica is melting faster than previously assumed, particularly in West Antarctica more than East Antarctica.

International team of evolutionary biologists investigate genomic underpinnings for the adaptive potential of spoonworts Plant cold specialists like the spoonworts have adapted well to the cold climates of the Ice Ages. As cold and warm periods alternated, they developed a number of species that also resulted in a proliferation of the genome.

Researchers have developed the first cell-free system in which genetic information and metabolism work together Metabolic processes outside living cells only continue as long as they are supplied with building blocks from the outside. A team of Max Planck researchers led by Tobias Erb has now developed the first in vitro system inspired by nature that couples genetics and metabolism and can drive itself.

An international team of researchers has investigated the mechanism that makes some types of bacteria reflect light without using pigments. The researchers were interested in the genes responsible and discovered important ecological connections. These findings were published in the current issue of the renowned journal Proceedings of the National Academy of Sciences (PNAS).

How Cities Can Adapt to Climate Change with Artificial Intelligence
The Freiburg project 'I4C - Intelligence for Cities' has developed locally precise climate models and foundations for planning tools Urban spaces are particularly susceptible to the effects of climate change, such as heat waves, floods, and storms. But which areas of a city are affected, and how can city planners respond? 'I4C - Intelligence for Cities' is an interdisciplinary project conducted by the University of Freiburg and several Fraunhofer Institutes.

Researchers from the Senckenberg Centre for Human Evolution and Palaeoenvironment (SHEP) at the University of Tübingen and the Senckenberg Natural History Museum in Görlitz have studied the role of the desert grass Stipagrostis sabulicola in the African Namib Desert. In their study, published in the journal Scientific Reports , they show that the plant is able to absorb moisture from fog events and thus forms an essential basis of an - altogether unexpectedly complex - food web in the drought-stricken landscape.

Researchers from Konstanz have measured the heart rate of bats over several days in the wild, including complete flights - the first time this has been done for a bat species. To record the heart rate of male common noctule bats during flight, the scientists attached heart rate transmitters weighing less than one gram to the animals, which they then accompanied in an airplane while the bats flew, sometimes for more than an hour, in search of food.

The EU Emissions Trading System is not only good for reducing CO2 and for the climate. It also results in considerable health benefits due to reduced air pollution and saves hundreds of billions of euros, according to a recently released study by a team at Universität Hamburg. The research team from the Cluster of Excellence Climate, Climatic Change, and Society (CLICCS) at Universität Hamburg analyzed the indirect effects of the European Emissions Trading System (EU ETS) on hazardous air pollutants such as sulfur oxide, particulate matter, and nitrogen oxides.

A guest commentary by biologists Niklas Kästner and Tobias Zimmermann, editors of the online magazine "ETHOlogisch - Verhalten verstehen" ("ETHOlogical - Understanding Behaviour") A mouse which disappears in a hole, a bee heading for a blossom, a blackbird in full-throated song - we are surrounded by animals which interact with their environment in certain ways.

Solar Technology: Light-Harvesting System Works Very Efficiently
Würzburg researchers from the Bavarian initiative Solar Technologies Go Hybrid are reporting progress on the road to more efficient utilisation of solar energy: they have developed an innovative light-harvesting system. In order to convert sunlight into electricity or other forms of energy as efficiently as possible, the very first step is an efficient light-harvesting system.

Biodiversity as the key to healthy soils and climate buffers
News from Two new papers published by researchers from Leipzig University and its partner institutions shed light on the complex relationships between biodiversity, soil and climate. They show how human influences and climate change are jeopardising our environment and emphasise the need for integrated solutions that promote sustainability and social justice.

Eleven mines and 57 recycling plants fewer: economic and ecological potential for savings on material consumption for electromobility in Europe The demand for electric vehicles which run on batteries is increasing worldwide. At the same time, resources of primary battery materials - i.e. those obtained from mining activities - are limited.

In a warming climate, cloud patterns change in such a way that they exacerbate global warming. A research group led by Johannes Quaas from Leipzig University and Hao Luo and Yong Han from Sun Yat-sen University in China has discovered that the cloud cover is increasingly showing asymmetrical changes: it decreases more during the day than at night.

Botanical gardens are found all'over the world and are home to plants from all'over the world. They are therefore ideal study platforms for researchers to find out how different plants react to changes - for example as a result of climate change. Numerous scientific studies are now being carried out in cooperation with botanical gardens, including the "PhenObs" project of the German Centre for Integrative Biodiversity Research Halle-Jena-Leipzig (iDiv) .

TUM Scientists Develop New Method for Early Detection of Climate Tipping Points Abrupt shifts within complex systems such as the Earth's climate system are extremely hard to predict. Researchers at the Technical University of Munich (TUM) and the Potsdam Institute for Climate Impact Research (PIK) have now succeeded in developing a new method to anticipate such tipping points in advance.

Less waste, mild reaction conditions, and no harmful solvents - only a very thin layer of gold is necessary to sustainably convert alcohols into aldehydes through mechanochemistry. A gold-coated milling vessel for ball mills proved to be a real marvel in the research work by Inorganic Chemistry at Ruhr University Bochum, Germany: Without any solvents or environmentally harmful chemicals, the team led by Professor Lars Borchardt was able to use it to convert alcohols into aldehydes.

A new study published in the journal Nature Communications shows that grassland and arable land could better provide different services at the same time if the use of pesticides and mineral fertilizers is reduced. According to the researchers from the German Centre for Integrative Biodiversity Research (iDiv), the Helmholtz Centre for Environmental Research (UFZ), Leipzig University (UL) and Martin Luther University Halle-Wittenberg (MLU), these results also apply under possible future climate conditions.

Led by the University of Bremen, RWTH paleoclimate researcher Professor Thorsten Bauersachs and colleagues have now published their results on the glaciation of West Antarctica in the journal Science Advances. It has been more than 30 million years since West Antarctica was last largely ice-free. In the last 30 million years, however, it has been extensively glaciated.
