Turning One into Eight
Turning One into Eight
University of Bonn chemists invent technique for producing variants of natural substances To synthesize potential drugs or natural products, you need natural substances in specific mirror-image variants and with a high degree of purity. For the first time, chemists at the University of Bonn have succeeded in producing all'eight possible variants of polypropionate building blocks from a single starting material in a relatively straightforward process.

As easy as counting to ten - a new rule for catalysts' design
As easy as counting to ten - a new rule for catalysts’ design
The 'ten electron rule' provides guidance for the design of single-atom alloy catalysts for targeted chemical reactions. A collaborative team from three British universities and from Humboldt-Universität have discovered a very simple rule to design single-atom alloy catalysts for chemical reactions.

Why orange juice sometimes smells of cloves
Why orange juice sometimes smells of cloves
Researchers see detergent residues as the cause Industrially produced orange juice sometimes smells unpleasantly of cloves. A research team led by the Leibniz Institute for Food Systems Biology at the Technical University of Munich (TUM) has now solved the mystery surrounding this undesirable off-odor.

GPT-3 for Chemical Research
GPT-3 for Chemical Research
GPT-3, the language model behind the well-known AI system ChatGPT, can also be utilised in chemistry to solve various scientific tasks. This was demonstrated by a team of researchers at the École Polytechnique Fédérale de Lausanne (EPFL), Friedrich Schiller University Jena, and the Helmholtz Institute for Polymers in Energy Applications (HIPOLE) Jena.

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.

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.

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.
