Cancer Research: DNA Repair Mechanism Further Elucidated
Researchers at the University of Würzburg, led by Caroline Kisker in cooperation with Claudia Höbartner, discovered how the protein XPD detects a severe DNA damage and controls its repair. The XPD protein is a central component of our body's own 'DNA repair team', known as nucleotide excision repair (NER).

New Insights Into the Evolution of the Prion Protein
New Insights Into the Evolution of the Prion Protein
A study from Bochum describes a mammal-specific domain of the prion protein and offers new approaches for research into neurodegenerative diseases. At first, they cause memory deficits and difficulties in walking, finally they inhibit elementary motor skills and destroy basic brain functions: Prion diseases are progressive and invariably fatal neurodegenerative diseases.

International research team cracks a hard physics problem
International research team cracks a hard physics problem
Strongly interacting systems play an important role in quantum physics and quantum chemistry. Stochastic methods such as Monte Carlo simulations are a proven method for investigating such systems. However, these methods reach their limits when so-called sign oscillations occur. This problem has now been solved by an international team of researchers from Germany, Turkey, the USA, China, South Korea and France using the new method of wavefunction matching.

How to Make Ubiquitous Plastics Biodegradable
Understanding the function of a specific bacterial enzyme has paved the way for the biotechnological degradation of styrene. Polystyrene is made from styrene building blocks and is the most widely used plastic in terms of volume, for example in packaging. Unlike PET, which can now be produced and recycled using biotechnological methods, the production of polystyrene has so far been a purely chemical process.

Evolutionary algorithm generates tailored 'molecular fingerprints'
Evolutionary algorithm generates tailored ’molecular fingerprints’
Team at the University of Münster develops an improved method for explaining machine predictions of chemical reactions Artificial intelligence and machine learning are becoming more and more relevant in everyday life - and the same goes for chemistry. Organic chemists, for example, are interested in how machine learning can help discover and synthesise new molecules that are effective against diseases or are useful in other ways.

New Function of Oncoproteins
New Function of Oncoproteins
Researchers at the University of Würzburg have discovered a new function of the oncoprotein MYCN: It not only helps cancer cells to grow stronger, but also makes them more resistant to drugs. Oncoproteins are actually vital to human survival: thousands of them in our bodies ensure that cells grow and divide.

Molecular dynamics in real time
Molecular dynamics in real time
A European research team has developed a novel spectroscopic method that can be used to observe ultrafast dynamic processes of electrons and vibrations within molecules - with atomic resolution and in real time. A team from the University of Jena supported the experimental team in Barcelona in the theoretical description of the processes.

Directly in the nose: antimicrobial peptide fights pathogenic bacteria
Directly in the nose: antimicrobial peptide fights pathogenic bacteria
Research team involving the University of Göttingen decodes molecular function . As humans, we are constantly accompanied by billions of microorganisms that live on our skin or in our airways in the form of our microbiome. The relationships between these microorganisms are a rich source of previously unknown metabolic products that are beneficial to humans.

Safer alternative for an explosive reaction
Safer alternative for an explosive reaction
For over 100 years, the chemical industry has been using explosive aryl diazonium salts to produce paints, for example. A team from the Max Planck Institute for Coal Research has now discovered a safer alternative for the processes in which the chemical is used. The researchers are mimicking a reaction that plants use to reduce nitrate, using chemicals that the chemical industry uses to produce fertilizers - which could also make the processes more cost-effective.

Breakthrough for battery production with sulphur cathodes
Breakthrough for battery production with sulphur cathodes
Electromobility and portable electronic devices such as laptops and cell phones are unthinkable without the use of lithium-ion batteries. The problem: highly toxic materials such as cobalt are often used for the cathodes of these batteries, which endanger the environment and the health of people in the countries where they are mined.

Peptides on Interstellar Ice
Peptides are organic compounds that play a crucial role in many biological processes, for example, as enzymes. A research team led by Dr Serge Krasnokutski from the Astrophysics Laboratory at the Max Planck Institute for Astronomy at the University of Jena had already demonstrated that simple peptides can form on cosmic dust particles.

New Ways to Fine Tune Electrochemistry
New Ways to Fine Tune Electrochemistry
Scientists have found new paths to steer and optimize electrochemical processes. Optimizing electrochemical reactions is essential for the transition to renewable energies. In electrochemical reactions, electric currents and potential differences are used to binding and induce reactions. Electrochemistry is a pre-requisite for hydrogen production, and for batterie technology, and thus for sustainable chemistry.

Harnessing hydrogen at life’s origin
Researchers gain new insights into how the first cells on Earth were able to use hydrogen gas as an energy source Hydrogen gas (H2) is seen as a key to sustainable energy for the future. Yet it is an ancient form of energy. Even the very first cells on earth lived on H2, which was produced in hydrothermal vents.
