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…

On the way to symbiosis
Two organisms of different species reproduce. Because they are two different species, mutations occur in this way. Researchers at the Max Planck Institute for Terrestrial Microbiology have now discovered how co-operation between different microorganisms can develop and how a mutual benefit emerges. The study, which has been published in the journal Nature Communications, is the…
