Study Genes for setting the ‘internal clock’ are closely linked to the ageing process
Genes that control the day-night rhythm are completely different with increasing age than in earlier phases of life. This biological function appears to be directly at the centre of many ageing processes, as a study published in the journal Aging Cell by the University Medical Centre Halle shows. The analysis examined the gene activity of…

A new look at aging
Research team at Freie Universität Berlin discovers surprising differences in ageing bacterial cells A research team at Freie Universität Berlin led by biologist Dr Ulrich Steiner has gained surprising insights into ageing in bacteria. In a new study, which has now been published in the renowned journal Science Advances, the team shows that even genetically…

Origin of life A new scenario for replication
LMU researchers discover a plausible geological constellation that could have triggered the origin of life on Earth Munich, October 25, 2024 – The origin of life on Earth is still an unsolved mystery, but a common theory suggests that the replication of genetic material – the nucleic acids DNA and RNA – was a central…

From chaos to order – how robust embryos form
A single egg cell is fertilised – it starts to divide continuously. The young embryo slowly assembles. The initially chaotic cluster of cells gradually develops into highly organised structures. An international research team, including scientists from the Institute of Science and Technology Austria (ISTA), has now gained new insights into this process. The results, which…

Evolution evolves A new scientific understanding of evolution is emerging
The „natural selection“ discovered by Charles Darwin remains the central mechanism even after many discoveries in recent years. New discoveries are moving in the direction of deeper specialisations of heritable traits and characteristics. A forthcoming book will show new perspectives on how the evolutionary process has evolved over time and continues to do so. Ploen,…

A little old, or eternally young?
Anatomical changes as well as an increasing slowdown in ageing have been proven in the meantime and can also be perceived with awareness in the population. In addition to internal ageing and wear and tear, ageing is also clearly perceptible through the skin. In a project funded by the Federal Ministry of Education and Research…
