The production of offspring involves costs for the own body. Therefore, in many animal species a high reproductive success at a young age is associated with a shortened lifespan. Queens of social insects such as ants, bees, wasps, and termites are an exception: they live very long lives and are highly productive until the end of their days, so they do not seem to age. Part of the mystery of how they do this has now been solved in the publication "Late-life fitness gains and reproductive death in Cardiocondyla obscurior ants", produced by a DFG-funded research group (FOR2281 Sociality and the reversal of the fecundity/longevity trade off).
Scientists from University of Regensburg, Massachusetts Institute of Technology, Moscow institute of Physics and Technology, and University of Kansas have discovered abnormally strong light absorption in graphene. The effect arises from the conversion of ordinary electromagnetic waves into super-slow surface waves running through graphene. This behavior could serve as the basis for extremely sensitive infrared and terahertz detectors much smaller than existing ones, with similar absorption efficiency. The investigations were carried out in the framework of the Collaborative Research Centre 1277 and published in the prestigious journal Nature Physics.
UR scientists explore electronic circuits without heat dissipation
Physicists from the University of Regensburg publish results in the internationally renowned journal “Nature Communications” A large international research collaboration led by Dr Kai-Qiang Lin and Professor John Lupton from the Institute of Experimental and Applied Physics at the University of Regensburg has been able to measure the effect of electrons with negative mass in novel semiconductor nanostructures. The international team includes scientists from Berkeley and Yale (USA), Cambridge (England) and Tsukuba (Japan).
Scientists from the University of Regensburg (Germany) and Université de Tours (France) found out how the Cardiocondyla elegans finds her partner
A Ten-Year Mentoring Journey Begins for the World’s Most Outstanding 119 Students in STEMM and their 119 World-Class Mentors
Regulatory T cells (Treg cells) are an immune cell type that reduces excessive immune responses and protects the body against autoimmune diseases. This study shows that Treg cells in human tissues acquire tissue-regenerative features and describes a method to generate these cells in the laboratory.
RCI and UKR scientists identified the transcription factor EGR2 as a major orchestrator of DNA methylation landscapes in human blood monocytes.
Physicists from the University of Regensburg develop a new method for counting molecules
Researchers in the field of mathematics education at the University of Regensburg together with medical education researchers at the LMU University Hospital of Munich have found that medical diagnoses can be made more often correctly and even faster with the help of natural frequencies and natural frequency trees. The researchers explain their findings in a recently published article in Advances in Health Sciences Education.
