A study involving the Cluster of Excellence ECONtribute at the Universities of Bonn and Cologne demonstrates that not only retail investors but also financial professionals often assess potential stock market returns differently from what standard financial economics models predict. This is due to differing ideas about how company news affects future stock returns. The study, titled "Mental Models of the Stock Market," was published in the Quarterly Journal of Economics.

Researchers from Vrije Universiteit Brussel (VUB) and KU Leuven have found that incomplete reference data account for most of the alleged decline in scientific disruption. Their article is also published in the journal Nature.

Researchers are developing biotechnological processes that enable microbes to produce proteins and vitamins for human consumption using basic chemical ingredients, such as carbon dioxide, hydrogen and oxygen—entirely bypassing livestock farming and agriculture. Because these methods also require energy input, they are popularly called "power-to-protein" and "power-to-vitamin" processes.
