Thriller in the bacterial kingdom

Who would have thought it of bacteria: they are capable of sneaking up on other microorganisms to kill and eat them

15-Sep-2022

Bacteria have a variety of survival strategies to ensure a sufficient food supply in their densely populated habitats. Certain species of bacteria kill microorganisms of another species, decompose their cells and absorb them as nutrients. The exact mechanism of this process is largely unknown. A ...

3D printed surfaces inspired by nature

Biologically inspired structural colours for anti-counterfeiting applications

14-Sep-2022

Scientists can use laser radiation to print tiny structures with high precision. This approach enables them to mimic the superpowers of animals and plants and makes them accessible for engineering applications. To survive in extreme habitats, many animals and plants have developed brilliant ...

How hepatitis E tricks the immune system

Defective virus particles could be a decoy to distract the immune system from fighting infectious viruses

18-Aug-2022

Over three million people are infected with the hepatitis E virus every year. So far, no effective treatment is available. An international team has investigated which factors are important for the virus in the course of its replication cycle and how it manages to maintain the infection. The ...

Artificial intelligence folds RNA molecules

New structures reliably predictable

12-Jul-2022

The spatial structure of RNA molecules is crucial for their function. But predicting it is a challenge. For the function of many biomolecules, their three-dimensional structure is crucial. Researchers are therefore not only interested in the sequence of the individual building blocks of ...

I was here first! This is how hepatitis C inhibits hepatitis E

A single protein from one virus can prevent infection with another virus in cell culture

31-Mar-2022

Infections with hepatitis C and E are so common that, going only by statistics, many people should be infected with both viruses at the same time. However, only very few such cases have been reported. A research team from the Department of Molecular and Medical Virology at Ruhr-Universität Bochum ...

New method provides more precise information on types of leukaemia

Optical genome mapping could become a component of routine diagnostics

21-Feb-2022

In the characterization of leukaemias, also known as blood cancers, genetic analyses are crucial and provide information for the optimal treatment strategy. A research team from Bochum and Essen has used a new method that offers greater accuracy in this process. The so-called optical genome ...

A treasure map for the realm of electrocatalysts

Research into promising materials is hampered by the sheer number of possible candidates: An efficient method to solve this problem now developed

17-Jan-2022

Efficient electrocatalysts, which are needed for the production of green hydrogen, for example, are hidden in materials composed of five or more elements. A team from Ruhr-Universität Bochum (RUB) and the University of Copenhagen has developed an efficient method for identifying promising ...

Catalyst surface analysed at atomic resolution

Particles observed during the catalysis process

12-Jan-2022

Catalyst surfaces have rarely been imaged in such detail before. And yet, every single atom can play a decisive role in catalytic activity. A German-Chinese research team has visualised the three-dimensional structure of the surface of catalyst nanoparticles at atomic resolution. This structure ...

How positively and negatively charged ions behave at interfaces

When charged particles enter the boundary layer between a liquid and an electrode, they first have to strip off their water shells

24-Nov-2021

How positively and negatively charged ions behave at the interface between a solid surface and an aqueous solution has been investigated by researchers from the Cluster of Excellence RESOLV at the Ruhr-Universität Bochum, its sister research network CALSOLV in Berkeley, and the University of Evry ...

What happens in brain cells affected by Alzheimer’s disease?

Studies on tissue from patients and mini-brains made from stem cells shed light on the disease

15-Jun-2021

In addition to plaques that accumulate outside of nerve cells in the brain, Alzheimer’s disease is also characterised by changes inside these cells. Researchers from the Cell Signalling research group at the Chair of Molecular Biochemistry at RUB, headed by Dr. Thorsten Müller, have been studying ...
