Thawing permafrost releases greenhouse gas from depth

Which effects did the heat wave of summer 2020 have in Siberia? In a study led by the University of Bonn, geologists compared the spatial and temporal distribution of methane concentrations in the air of northern Siberia with geological maps. The result: the methane concentrations in the air after last year's heat wave indicate that increased gas emissions came from limestone formations beneath the thawing permafrost. The study is published in the journal Proceedings of the National Academy of Sciences (PNAS).

Seeing better by looking away

When we fixate an object, its image does not appear at the place where photoreceptors are packed most densely. Instead, its position is shifted slightly nasally and upwards from the cellular peak. This is shown in a recent study conducted at the University of Bonn, published in the journal Current Biology. The researchers observed such offsets in both eyes of 20 healthy subjects, and speculate that the underlying fixation behavior improves overall vision.

“Who makes history?” The return of the person-centered approach

What influence do individual personalities have on political decisions and the course of history?

Economy: Michael-Burkhard Piorkowsky highlights the importance of households

“Economics is a human thing,” says a convinced Michael-Burkhard Piorkowsky. The researcher, who held the Professorship for Household and Consumption Economics at the University of Bonn before his retirement, has written a book that takes this statement as its title.

Paleontologists reveal what fossilized teeth can tell us

Teeth are the toughest and most durable parts of a mammal’s body and are often the only bits of fossils left after millions of years. We join Prof. Dr. Thomas Martin to explore the secret of teeth.

Researching across discipline boundaries: mathematician Florian Brandl grapples with economic theory

How can several stakeholders make decisions as one when they possess different information or need to take uncertainties into account? This and other questions are on the plate of mathematician and economic theorist Dr. Florian Brandl, who took up the first Argelander Professorship in the Transdisciplinary Research Areas (TRAs) on April 1 and started work as a Bonn Junior Fellow at the Hausdorff Center for Mathematics at the same time. He is the first researcher to hold such a professorship, one of several new posts created for exceptional early-career researchers who excel in combining several different disciplines. In the case of Florian Brandl’s research, these are mathematics, economics and computer science. An article from forsch 2021/01.

Students develop a children's book on fundamental rights with Gigi the eagle

Gigi the eagle is searching for her young. However, the proud bird is not alone – helping her are two children, Ben and Mia. On the pages of a new book created by students, primary school children can read an adventure story while learning about Germany’s fundamental rights at the same time. To understand how this children’s book came about, it is worth rewinding three years. An article from forsch 2021/01.
