Stigmatization prevents lessons from the HIV pandemic

Bielefeld researchers look at the consequences for Covid-19 in ‘Science’

The HIV pandemic hit the LGBTQI+ community particularly early: people who were already stigmatized. This stigmatization prevented the lessons of the HIV pandemic from being adopted by broader parts of society—with consequences for dealing with the Covid 19 pandemic, argue researchers from the School of Public Health at Bielefeld University. In the journal Science, they show how society could learn better from the experiences of stigmatized communities. Their contribution is part of a project at the Research Institute Social Cohesion (FGZ) funded by the Federal Ministry of Education and Research.

Tiny nanoparticles improve charge transport

Bielefeld researchers publish study on topological insulators

Three-dimensional topological insulators are materials that can conduct electric current without resistance—but only on their surface. However, this effect is difficult to measure. This is because these materials usually have little surface area in relation to their volume, which means their transport properties are dominated by bulk charge carriers. Bielefeld University physicists have now succeeded in developing topological insulators based on tiny nanoparticles and have thus been able to demonstrate charge transport on the surface. The study was conducted in cooperation with researchers from the University of Duisburg-Essen and the Leibniz Institute for Solid State and Materials Research Dresden. The scientists have published their results today (21.9.2021) in the journal Small. The European Research Council ERC funded the study with a Consolidator Grant.

How genetic islands form among marine molluscs

International study appears in the research journal Science Advances

Das Bild zeigt Napfschnecken, die aufeinanderklettern.
Usually, the individuals of a population of marine species that have the potential to disperse over long distances all share a similar genetic composition. Yet every now and then, at small, localised sites, small groups of genetically different individuals suddenly appear within populations for a short period of time. A new study explains how this chaotic formation of genetic islands can occur in marine molluscs. Scientists from Bielefeld University and the British Antarctic Survey collaborated on the research. Their study has appeared in Science Advances.

How turbulence from a tidal turbine structure affects terns

Drones used for the first time to map tidal currents and foraging flights

Sandwich Tern in front of SeaGen tidal power plan
Tidal energy converters use strong tidal currents to power underwater turbines in much the same way as wind turbines. Hardly any research has so far been conducted on how their turbulent wakes may impact the marine environment. A recent international study shows: the wake of a tidal energy structure influences how terns search for food. Researchers from Bielefeld University, Queen’s University Belfast (Northern Ireland), and the University of Plymouth (England) collaborated for the study. For the first time, drones have been used to simultaneously track the movements of terns and the turbulent wake of a tidal turbine structure. The research team presents their analysis of the extensive data in the journal Proceedings of the Royal Society B: Biological Sciences.
