Drawing board rather than salt shaker: The clever arrangement of bacterial genes

"The results really surprised us"

15-Apr-2025 - Bioinformaticians from Heinrich Heine University Düsseldorf (HHU) and the University in Linköping (Sweden) have established that the genes in bacterial genomes are arranged in a meaningful order. In the scientific journal Science, they describe that the genes are arranged by function: If they ...

How an organelle evolves

From independent single-celled organisms to cell organelle

21-Mar-2025 - Organelles in cells were originally often independent cells, which were incorporated by host cells and lost their independence in the course of evolution. A team of biologists headed by Professor Dr Eva Nowack at Heinrich Heine University Düsseldorf (HHU) are examining the way in which this ...

Surprising finding: Mothers massively change their intestines during pregnancy and nursing

Scientists discover the molecular and structural principles of intestinal changes in pregnancy, critical for nutrient uptake and the health of babies

06-Dec-2024 - When women are pregnant and nurse their babies, their bodies change and various organs, such as the breasts or the immune system, are adapted to ensure the health of both mother and child. This happens throughout evolution in all mammals. An international research team led by Josef Penninger, ...

A Journey back in time to the origin of stem cells

Proteins that regulate animal stem cells are much older than animals themselves

20-Nov-2024 - A new study published in Nature Communications reveals that critical proteins involved in animal stem cell regulation are much older than previously thought, predating the origin of animals that likely evolved more than 700 million years ago. The international research team included scientists ...

Evolutionarily Youngest Brain Regions Age First

"Our findings could contribute to the development of new treatment and prevention approaches for neurodegenerative diseases such as Alzheimer's"

20-Sep-2024 - A research team from Forschungszentrum Jülich and Heinrich Heine University Düsseldorf has discovered that the regions of the human brain that have expanded most recently in the course of evolution show the strongest aging effects. This is evident from comparisons with brain ageing in our closest ...
