Surprisingly vibrant colour of 12-million-year-old snail shells
Surprisingly vibrant colour of 12-million-year-old snail shells
Researchers provide world's first evidence of intact polyene pigments in fossils Snail shells are often colourful and strikingly patterned. This is due to pigments that are produced in special cells of the snail and stored in the shell in varying concentrations. Fossil shells, on the other hand, are usually pale and inconspicuous because the pigments are very sensitive and have already decomposed.

International Science Team Intensifies Research on Lithium-Sulfur Batteries
International Science Team Intensifies Research on Lithium-Sulfur Batteries
Joint project -AReLiS-3- commences at MEET Battery Research Center A research team at the MEET Battery Research Center at the University of Münster has kicked off the international joint project "AReLiS-3" to pursue research on lithium-sulfur batteries. Its aim is to develop, investigate and optimize novel cell designs, materials, electrode coatings and electrolytes for sulfur-based battery systems.

Green steel from toxic red mud
Green steel from toxic red mud
An economical process with green hydrogen can be used to extract CO2-free iron from the red mud generated in aluminium production The production of aluminium generates around 180 million tonnes of toxic red mud every year. Scientists at the Max-Planck-Institut für Eisenforschung, a centre for iron research, have now shown how green steel can be produced from aluminium production waste in a relatively simple way.

Cosmic building blocks of life discovered through the electron microscope
Cosmic building blocks of life discovered through the electron microscope
For the first time without any chemical treatment, a research team analyses extraterrestrial amino acids and other organic compounds in an English meteorite fall Meteorites are fragments of asteroids which find their way to Earth as shooting stars. These cosmic sediments have frozen the primordial soup from which our solar system emerged - preserving it just like a time capsule.

Precise measurements of the heaviest atoms
Precise measurements of the heaviest atoms
An international research team has successfully conducted ultra-precise X-ray spectroscopic measurements of helium-like uranium. The team, which includes researchers from Friedrich Schiller University Jena and the Helmholtz Institute Jena, has published results demonstrating their success in disentangling and separately testing one-electron two-loop and two-electron quantum electrodynamic effects for extremely strong Coulomb fields of the heaviest nuclei for the first time.

Networkers in cramped conditions
More than 1,000 players are involved in a cell when genetic information is translated into proteins. A new German-Israeli research project is now working on systematically identifying their respective tasks. When genetic information in human cells is transported from the cell nucleus into the cytoplasm and translated into proteins, one particular molecule plays a central role: mRNA, or messenger RNA.

How the coronavirus defends itself against our immune system
How the coronavirus defends itself against our immune system
Research team identifies protective switch in SARS-CoV-2 virus protein . With over 700 million people infected and almost seven million dead, the global spread of Covid-19 has been the most devastating pandemic of the 21st century to date. Vaccines and medication against the SARS-CoV-2 coronavirus have been able to mitigate the course of the disease in many people and contain the pandemic.

Chemical synthesis: new strategy for skeletal editing on pyridines
Chemical synthesis: new strategy for skeletal editing on pyridines
Chemists at the University of Münster realised -chemical surgery- on ring-shaped compounds / Results published in -Nature Chemistry- In the field of chemistry, so-called skeletal editing is seen as a method suitable for changing ring-shaped structures precisely by swapping individual atoms.

Metabolic alteration to increase the stress tolerance of tobacco plants
Metabolic alteration to increase the stress tolerance of tobacco plants
Plant biotechnologists elucidate the mechanism that leads to higher seed yields in tobacco plants by transporting fatty acids - in addition to sugar - via the nutrient-carrying transport vessels When there is drought, a pathogen attack, or too much salt in the soil, plants are faced with a constant series of stress factors.

Chemists develop new approach to inserting single carbon atoms
Skeletal editing employed to enlarge molecule rings Molecules with a central ring system play an important role in the search for active ingredients for new pharmaceutical products - and it is important that the rings should have the correct size if the desired product is to be manufactured as efficiently as possible.
