Less advertising for high-calorie snacks on children's TV

The number of overweight children has increased significantly. In addition to psychological problems, chronic diseases such as diabetes, high blood pressure and joint wear and tear are on the rise. Some food and beverage companies have signed a voluntary commitment at EU level to restrict advertising of foods high in fat, sugar and salt to children. A study by scientists at the University of Bonn shows: The number of corresponding commercials aimed at children decreased in Germany once this agreement had been put in place, but the companies also exploit loopholes. The results have now been published in the journal "Food Policy".

Unlocking the secret of cell regulation

Ribonucleic acids (RNA) ensure that the blueprint in the cell nucleus is translated into vital proteins and that cell functions are regulated. However, little is known about the structure and function of particularly long RNAs, which consist of hundreds or thousands of building blocks. Chemists at the University of Bonn have now developed a new method for this purpose: They mark the complex molecules with tiny "flags" and measure the distances between them with a "molecular ruler". The results are published online in advance in the journal "Angewandte Chemie International Edition". The print version will be published shortly.

New method for removing oil from water

Oil poses a considerable danger to aquatic life. Researchers at the Universities of Bonn and Aachen and the Heimbach-GmbH have developed a new technology for the removal of such contaminations: Textiles with special surface properties passively skim off the oil and move it into a floating container. The scientists used surfaces from the plant kingdom as a model. The study has now been published in the journal "Philosophical Transactions A".

Climate change affects soil health

Climate change is affecting the health of agricultural soils. Increased heat and drought make life easy for the pathogenic fungus Pythium ultimum. As an international team of researchers led by the Universities of Kassel and Bonn has shown, the fungus causes almost total crop failure in peas after a hot and dry stress event. Short-term soil recovery seems to be possible only in exceptional cases. The study has now been published in the journal "Applied Soil Ecology".

Open research data: University of Bonn participates in "Sorbonne Declaration"

Nine associations of international top universities have spoken up for open research data. The associations represent more than 160 of the largest and most renowned universities from many parts of the world, including the United States, Canada, Australia, Europe, Asia and Africa. The University of Bonn is involved as a member of the German U15 network.
