The Negative Impact of Climate Change on Freshwater Bodies

A lot of research is being conducted into the acidification of the world’s oceans. A recent study has proved that freshwater bodies are likewise affected. Rising carbon dioxide levels could upset the balance of species.

When Friends Become Objects

Why do people use social media? Striving to answer this question, social psychologists at Ruhr-Universität Bochum (RUB) have conducted a survey with more than 500 Facebook users with regard to their personality structure and the way they use the platform. Based on the results, they have developed the first comprehensive theory of social media usage. According to that theory, self-regulation is the key: we use Facebook in a way that makes us feel good and hope to attain our objectives. The research team manned by Phillip Ozimek, Fiona Baer and Prof Dr Jens Förster published their report in the journal Heliyon on November 20, 2017.

Why plants form sprouts in the dark

Exposed to light, plants turn green and form leaves. Not so in the dark. A signal responsible for this phenomenon has now been decoded.

How Continents Were Recycled

Researchers from Germany and Switzerland have used computer simulations to analyse how plate tectonics have evolved on Earth over the last three billion years. They show that tectonic processes have changed in the course of the time, and demonstrate how those changes contributed to the formation and destruction of continents. The model reconstructs how present-day continents, oceans and the atmosphere may have evolved.

How selenium compounds might become catalysts

Chemists at Ruhr-Universität Bochum have tested a new approach for activating chemical reactions based on the element selenium. They demonstrated that selenium can form bonds similar to those of hydrogen bonds, resulting in accelerated reactions. The exact mechanism is described by the team at the Chair of Organic Chemistry 1 in Bochum, including Prof Dr Stefan Huber and Patrick Wonner, in the journal “Angewandte Chemie”, in collaboration with Prof Dr Daniel Werz from Braunschweig University of Technology.Traditionally, metal complexes are used as activators and catalysts. They form complete, i.e. covalent bonds with the molecule whose reactions they are supposed to accelerate. However, the metals are often expensive or toxic.
