Instead of Downcycling… Carbon fiber reinforced plastics (CFRP) are increasingly being used in lightweight construction applications where high strength and rigidity combined with minimal weight are crucial. However, the growing use of CFRP is also accompanied by large quantities of carbon fiber waste. Conventional recycling processes significantly reduce the properties of CFRP and limit the areas of application. The German Institutes of Textile and Fiber Research Denkendorf (DITF) have developed highly oriented tapes made from recycled carbon fibers (rCF) that…

Researchers find a potential explanation for the unusually sudden temperature rise in 2023: reduced low-level cloud cover limits Earth’s ability to reflect solar radiation. Rising sea levels, melting glaciers, heatwaves at sea – 2023 set a number of alarming new records. The global mean temperature also rose to nearly 1.5 degrees above the preindustrial level, another record. Seeking to identify the causes of this sudden rise has proven a challenge for researchers. After all, factoring in the effects of anthropogenic…

What was the cause of the great Tōhoku earthquake of 2011, and how can we better understand geological processes in order to protect coastal infrastructure in the long term – for example, from a tsunami like the one 13 years ago? These questions are currently the focus of a scientific expedition as part of the International Ocean Discovery Program (IODP), in which researchers from the MARUM – Center for Marine Environmental Sciences at the University of Bremen are participating. Since…

– climate change causes more sediment in high-mountain rivers. Many high-mountain rivers in Asia transport more sediment downstream compared to a few years ago. Changes in sediment levels have a particularly strong impact on agriculture, water quality, flood management, and hydropower generation. A study with participation of the University of Potsdam demonstrates the interacting roles of glaciers, vegetation, precipitation, and slope in mobilizing sediment and controlling the current sediment transport in rivers. In order to counteract climate change, the authors…

The climate warms fastest in the Arctic. The sea ice there has become so thin that we could already see the first day without sea ice by 2030, according to a new study led by researchers from the University of Gothenburg, Sweden, and University of Colorado in Boulder, USA. Climate change has weakened the Arctic ice cover. Researchers found that if a series of not-that-unusual weather events were to take place under autumn, winter or spring, there is real risk…

With growing concerns over climate change and overpopulation, we urgently need to boost agricultural productivity. With the goal of creating a way to easily tell whether a plant is thriving or dying, a leaf-mounted sensor was created by researchers at Tohoku University. This small but mighty technology could help improve crop yields and resource management in order to meet ever-growing demands. Extreme weather events like heatwaves, heavy rain, and droughts stress plants, which can reduce crop yields and threaten the…

New approaches in the fight against bacterial rice disease. An international research team, the “Healthy Crops” consortium, has developed rice varieties resistant to a detrimental crop disease in East Africa and Madagascar. The new varieties are resistant to bacterial leaf blight (for short: BB), caused by the bacterium Xanthomonas oryzae pv. oryzae (Xoo). The intention is to transfer these varieties to local breeders in Madagascar and Tanzania, where they will first be subjected to field tests and subsequently distributed to…

EIP Project “BioStripPlant” Successfully Concludes. On Thursday, 28 November 2024, the Leibniz Institute of Vegetable and Ornamental Crops (IGZ) hosted the final event of the “BioStripPlant” project. Funded by the European Innovation Partnership (EIP-Agri) and coordinated by agrathaer GmbH, the project aimed to develop and test an innovative cultivation method for organic vegetable farming in Brandenburg. Over three years, the project explored how strip-tillage combined with mulch and live mulch systems could enhance soil conservation and climate resilience. The results…

With 2024 on track to be declared the hottest on record, scientists from IIASA and Columbia University have noticed that specific regions are consistently more affected by extreme temperatures. A new study provides the first worldwide map of these regional climate danger zones. Amid the continued upward march in average temperatures over the past decades, a recent surge of record shattering extreme heat waves raise questions about the degree to which climate models can provide adequate estimates of relations between…

Researchers at the University of Alaska Fairbanks and their industry partners have advanced the technology available to measure carbon dioxide in the ocean. Scientists around the world rely on ocean monitoring tools to measure the effects of climate change. Researchers at the University of Alaska Fairbanks and their industry partners have advanced the technology available to measure carbon dioxide in the ocean. Their design, published in the journal Ocean Science, is now available to the scientific community. During the past six…

CBS Presents the Concept of “Ethical World Trade”. CBS International Business School, in collaboration with the European Environmental Bureau, the Wellbeing Economy Alliance, and the World Fair Trade Organization, has developed the concept of “Ethical World Trade & Economy for the Common Good” to promote a fairer and more sustainable global trade framework. At the heart of this proposal is the integration of social and ecological standards into trade regulations. The concept combines climate protection, human rights, and local economic…

New measuring node was placed off Boknis Eck today. One of the oldest marine time series stations in the world is located in Eckernförde Bay, just under two kilometres off the coast: Boknis Eck. Since 1957, data on the state of the Baltic Sea have been collected regularly from a ship and, since 2016, also from an underwater observatory on the seafloor. After the device disappeared in 2019, the GEOMAR Helmholtz Centre for Ocean Research Kiel today launched a new,…

Study reveals low levels of common contaminants but high levels of other elements in waters associated with an abandoned lithium mine. Lithium ore and mining waste from a historic lithium mine located west of Charlotte, North Carolina, are unlikely to contaminate surrounding waters with common pollutants such as arsenic and lead, according to a new study. However, high levels of other metals — namely, lithium, rubidium and cesium — do occur in waters associated with the mine. The new findings,…

Plant biologists show how two genes work together to trigger embryo formation in rice. Rice is a staple food crop for more than half the world’s population, but most farmers don’t grow high-yielding varieties because the seeds are too expensive. Researchers from the University of California’s Davis and Berkeley campuses have identified a potential solution: activating two genes in rice egg cells that trigger their development into embryos without the need for fertilization, which would efficiently create high-yielding clonal strains…

Compared to intensive land use, sustainable land use allows better control of underground herbivores and soil microbes. As a result, the soil ecosystem is more resilient and better protected from disturbance under sustainable management than under intensive land use. Researchers from Leipzig University, the German Centre for Integrative Biodiversity Research (iDiv) Halle-Jena-Leipzig and other research institutions found that the total energy flux and the activities of so-called decomposers, herbivores and predators in the soil food web remained stable. They have…

Accompanied by around 400 guests, the ship naming ceremony was led by Karin Prien, Schleswig-Holstein’s Minister of Science, who assumed the role of sponsor for this remarkable vessel. CORIOLIS is a floating, multi-purpose laboratory with state-of-the-art equipment designed for coastal, hydrogen, and membrane research. It also represents a step toward environmentally friendly maritime technology, which empowers environmental protection and climate sensitivity. Applause broke out when the champagne bottle hit the bow of the CORIOLS and burst. The guests from politics,…
