At the same time, the immune system follows a 24-hour rhythm, as the number and activity of many immune cells fluctuate throughout the day. https://medicalxpress.com/news/2025-11-internal-clock-immune-cells-younger.html Immunology Wed, 12 Nov 2025 09:00:04 EST news682160402 Liver cells are indispensable for research—for drug testing, to better understand diseases such as hepatitis, fatty liver, cirrhosis, or liver cancer and for development of future cell therapies. However, obtaining human liver cells from biopsies and donor organs is challenging. Therefore, research requires alternative sources of liver cells. https://phys.org/news/2025-10-gene-modification-enables-functional-liver.html Cell & Microbiology Wed, 29 Oct 2025 10:19:03 EDT news680951941 Long shifts, irregular working hours, high time pressure, and social isolation: the work of freight train drivers is both physically and mentally demanding. A better understanding of the specific work-related stresses faced by freight train drivers can help make the profession more sustainable and attractive in the long term. https://phys.org/news/2025-09-key-psychosocial-stress-factors-freight.html Social Sciences Wed, 24 Sep 2025 12:34:03 EDT news677936041 Inducing acute stress reliably under controlled conditions remains a major challenge in scientific research. Finding paradigms that elicit stress reliably and remain ecologically valid is difficult. https://medicalxpress.com/news/2025-08-stress-affects-brain-invasive.html Psychology & Psychiatry Tue, 19 Aug 2025 16:00:03 EDT news674838001 How people evaluate odors does not depend entirely on the odorant itself—context influences perception. A research team from the Leibniz Research Center for Working Environment and Human Factors (IfADo) has worked with researchers from the Thuenen Institute of Wood Research in Hamburg to investigate whether wood odors are rated as significantly more pleasant when accompanied by a corresponding image of wood. https://phys.org/news/2025-08-visual-cues-boost-positive-perception.html Social Sciences Mon, 04 Aug 2025 09:31:58 EDT news673518712 A team of researchers from TU Dortmund University, the University of Paderborn, and the University of Nottingham has developed a new optical method to detect ultra-weak atomic motion. Their experiment performed in Dortmund has demonstrated unprecedented sensitivity of the detection of atomic motion in crystals by exploiting light interference. https://phys.org/news/2025-05-optical-technique-ultra-weak-atomic.html Condensed Matter Fri, 16 May 2025 10:11:03 EDT news666609061 Physicists at TU Dortmund University have periodically driven a time crystal and discovered a remarkable variety of nonlinear dynamic phenomena, ranging from perfect synchronization to chaotic behavior within a single semiconductor structure. The team has now published its latest findings in the journal Nature Communications. https://phys.org/news/2025-04-physicists-dynamic-phenomena-crystal.html Condensed Matter Wed, 02 Apr 2025 11:50:03 EDT news662813401 Professor Max Martin Hansmann from the Department of Chemistry and Chemical Biology and his team have developed a new reagent for selectively adding carbon atoms to molecules.

It seems that this also applies to narcissistic managers, as a research team led by Professor Lorenz Graf-Vlachy from TU Dortmund University has discovered. Narcissistic CEOs are inclined to appoint other narcissists to the management board. https://phys.org/news/2024-04-narcissistic-ceos-narcissists-board.html Social Sciences Wed, 24 Apr 2024 14:56:03 EDT news633189362 During cell division, a ring forms around the cell equator, which contracts to divide the cell into two daughter cells. Together with researchers from Heidelberg, Dresden, Tübingen and Harvard, Professor Jan Kierfeld and Lukas Weise from the Department of Physics at TU Dortmund University have succeeded for the first time in synthesizing such a contractile ring with the help of DNA nanotechnology and uncovering its contraction mechanism. The results have been published in Nature Communications. https://phys.org/news/2024-03-dna-nanotube-team-important-block.html Bio & Medicine Mon, 25 Mar 2024 13:03:03 EDT news630590581 In the future, modern machines should not only follow algorithms quickly and precisely, but also function intelligently—in other words, in a way that resembles the human brain. Scientists from Dortmund, Loughborough, Kiev and Nottingham have now developed a concept inspired by eyesight that could make future artificial intelligence much more compact and efficient. https://techxplore.com/news/2024-02-international-team-hardware-neuromorphic.html Hardware Wed, 07 Feb 2024 10:35:14 EST news626524510 A team from TU Dortmund University recently succeeded in producing a highly durable time crystal that lived millions of times longer than could be shown in previous experiments. By doing so, they have corroborated an extremely interesting phenomenon that Nobel Prize laureate Frank Wilczek postulated around ten years ago and which had already found its way into science fiction movies. https://phys.org/news/2024-02-physicists-highly-robust-crystal.html Condensed Matter Thu, 01 Feb 2024 10:45:39 EST news626006735
