Mathematics and music are to some extent related. So, when Aditya Ganesh, amateur musician and Master’s student of Computing Science at the University of Groningen, sat in a lecture on complex behaviour created by a simple formula, he saw the potential for a new music piece. It took him six months to convert a logistic map into a nearly eight minutes’ long composition called ‘Feigenbaum’s Orbit’.

Inflammatory bowel disease is accompanied by a number of changes in the intestines, such as a change in epithelial permeability, a change in the composition of the microorganisms, and altered levels of antimicrobial substances that are secreted by cells lining the gut. Finding out whether changes are a cause or an effect of the inflammation is difficult. Sahar El Aidy, a microbiologist at the University of Groningen, together with colleagues from San Diego (US), have now teased out the causal chain leading to inflammation.

Many animal species bury their eggs, for a number of different reasons. While it is firmly established that Eurasian penduline tits bury them because of sexual conflict, their Chinese counterparts seem to have an entirely different reason. Experimental manipulations show that for these birds burial prevents the eggs from falling out of the nest in strong winds.

In the first few billion years after the Big Bang, the universe contained far more so-called starburst galaxies than models predict. As many as 60 to 90 percent of the stars in the early universe appear to have been produced by galaxies undergoing a growth spurt. This is what an analysis of more than 20,000 distant galaxies show. The team, led by astronomers from University of Groningen (the Netherlands) will soon publish its findings in The Astrophysical Journal.

Bacteria and yeast need to prevent leakage of numerous small molecules through their cell membrane. Biochemists at the University of Groningen have studied how the composition of the membrane affects passive diffusion and the robustness of this membrane. Their results could help the biotech industry to optimize microbial production of useful molecules and help in drug design.

The intermittent supply of green electricity requires large-scale storage to keep our power grids stable. Since normal batteries do not scale very well, the idea of using flow batteries, which store electricity in a fluid is attractive. Scientists at the University of Groningen, the Netherlands, have designed a flow battery electrolyte that is cheaper and is based on an organic compound, rather than a metal.

If you want to treat a tumour, the chemotherapeutic drug has to travel through the patient’s entire body, potentially causing many side effects in healthy tissues. Scientists at the University of Groningen and the University Medical Center Groningen have produced a light-controlled ‘cage’ that ‘opens’ to deliver the drug to where it is needed.

All life evolves: microorganisms can become resistant to drugs, viruses evade our vaccines, and species may adapt to climate change. Even the ability to evolve can evolve. If we were to understand how this happens and which mechanisms play a role, it may be possible to predict evolution to some extent.

Sex roles in birds describe sex differences in courtship, mate competition, social pair-bonds, and parental care. Different explanations have been put forward to explain these differences but none are based on a comprehensive study. Therefore, an international team of experts set out to analyse data on 1,800 of the approximately 9,000 different species of birds as their study organisms.

If the UN Sustainable Development Goal to lift over one billion people out of poverty were to be reached in 2030, the impact on global carbon emissions would be minimal. That sounds good; however, the main reason for this is the huge inequality in the carbon footprint of rich and poor nations. This conclusion was drawn by scientists from the Energy and Sustainability Research Institute of the University of Groningen (the Netherlands), together with colleagues from China and the US.

Even at high concentrations, antibiotics won’t kill all bacteria. There are always a few survivors, even in a bacterial population that is genetically identical. Scientists at the KU Leuven (Belgium) and the University of Groningen (the Netherlands) discovered that these survivors share a common feature: they accumulate acid in their cells.
