New study shows how heat can be used in computing

Physicists at Martin Luther University Halle-Wittenberg (MLU) and Central South University in China have demonstrated that, combining specific materials, heat in technical devices can be used in computing. Their discovery is based on extensive calculations and simulations. The new approach demonstrates how heat signals can be steered and amplified for use in energy-efficient data processing. The team`s research findings have been published in the journal "Advanced Electronic Materials".

AI: Researchers develop automatic text recognition for ancient cuneiform tablets

A new artificial intelligence (AI) software is now able to decipher difficult-to-read texts on cuneiform tablets. It was developed by a team from Martin Luther University Halle-Wittenberg (MLU), Johannes Gutenberg University Mainz, and Mainz University of Applied Sciences. Instead of photos, the AI system uses 3D models of the tablets, delivering significantly more reliable results than previous methods. This makes it possible to search through the contents of multiple tablets to compare them with each other. It also paves the way for entirely new research questions.

Study: Underground car parks heat up groundwater

The heat given off by car engines warms up underground car parks in such a way that the heat passes through the ground into the groundwater. In Berlin alone, enough energy is transferred to the groundwater to supply 14,660 households with heat. This finding was made by a team from Martin Luther University Halle-Wittenberg (MLU), the Karlsruhe Institute of Technology, and the University of Basel. According to the researchers, this warming could have long-term effects on groundwater quality. In their study, published in the journal "Science of The Total Environment", they also propose a solution. Using geothermal energy and heat pumps, the heat could be extracted from the ground and utilised.

Scientists develop novel nanoparticles that could serve as contrast agents

Special nanoparticles could one day improve modern imaging techniques. Developed by researchers at Martin Luther University Halle-Wittenberg (MLU), the properties of these unique nanoparticles change in reaction to heat. When combined with an integrated dye, the particles may be used in photoacoustic imaging to produce high-resolution, three-dimensional internal images of the human body, the team reports in the journal "Chemical Communications".

Forest biodiversity: Mixed forests are more productive when they are structurally complex

The richer forests are in different tree species, the faster the trees grow and the more CO2 they can absorb. A joint study by TU Dresden, Leuphana University Lüneburg, Martin Luther University Halle-Wittenberg, University of Leipzig, University of Montpellier and the German Center for Integrative Biodiversity Research (iDiv) Halle-Jena-Leipzig sheds some light on the mechanisms behind this. The results have now been published in "Science Advances".
