Using light to activate mRNA: Biochemists use new tool to control mRNA by means of light
DNA (deoxyribonucleic acid) is a long chain of molecules composed of many individual components, and it forms the basis of life on Earth. The function of DNA is to store all genetic information. The translation of this genetic information into proteins - which an organism needs to function, develop and reproduce - takes place via mRNA (messenger ribonucleic acid).

Chemists develop new multi-component reaction
More environmentally friendly approach produces complex molecular structures in one step / Ketyl radicals "tamed" by photocatalysis A more sustainable use of chemical resources is part of the United Nations' Agenda 2030. Synthetic chemists are therefore working to design and carry out efficient syntheses.

Origins of carbonatite magma revealed
Carbonatite rocks are economically important. The many hundreds of known carbonatite deposits on all continents are important repositories of rare-earth metals such as lanthanum, cerium and neodymium. These are used in many key technologies, including smartphones, plasma and LCD screens, as well as in radiology for medical diagnoses, in generators in wind turbines, and in electric motors.

Chemists use light energy to produce small molecular rings
In the search for new active agents in medicine, molecules whose atoms are linked in rings are becoming increasingly important. Such ring systems have particularly suitable properties for producing such active agents and they are driving the development of innovative treatments for malignant tumours, as well as for neurodegenerative and infectious diseases.

Formation of carbonatite magmas decrypted
Carbonatite rocks are economically important: The hundreds of known fossil carbonatite deposits on all continents are important storage sites for rare earth metals such as lanthanum, cerium, and neodymium. They are used in many key technologies, including smartphones, plasma and LCD screens, medical diagnostic radiology, wind turbine generators, and electric motors.

Physicists study optically induced quantum dynamics in single-photon emitters
For tomorrow's quantum technologies: hexagonal boron nitride under the magnifying glass / findings published in -Optica- Quantum technologies are a seminal field of research, especially in relation to their application in communication and computing. In particular, the so-called single-photon emitters - materials that emit single light quanta in quick sequence - are an important building block for such applications.

Animal research: influence of experimenters on results less strong than expected
For more than ten years now, scientists have been discussing the so-called reproducibility crisis: often, scientific findings cannot be reproduced at a later time and/or in other laboratories, although the studies are carried out under highly standardised conditions. Thereby, standardisation includes for example the use of genetically identical animals, keeping the animals in identically equipped cages, and carrying out the experiments in always the same way.

Research team decodes human genome
"A big puzzle": How an international consortium has now completely decoded the human genome The human genome is like a puzzle - but a difficult one to solve: This puzzle has more than three billion pieces. And as if that were not challenging enough, the puzzle is made even more confusing by similar pieces as well as patterns that repeat themselves.

Fruit flies adapt activity to ’white nights’
Evolution takes place constantly, everywhere in nature. Nevertheless, it is always exciting for biologists to observe evolution "in real time". One such opportunity for observation is currently being presented by the internal clock, i.e. the innate sleep-wake rhythm, of the fruit fly Drosophila melanogaster .

MEET Team presents Toolbox for Analysis of End-of-Life-Batteries
Compared to laboratory cells or aged but still intact commercial cells, shredded battery materials represent an even more complex sample. Active materials of both electrodes, inactive materials and electrolyte residues cannot be easily analysed separately.

Chemists discover new reactivity of strained molecules
In synthetic organic chemistry, so-called cycloadditions are a particularly important class of reactions. With this type of reaction, ring-shaped molecules can be constructed simply and efficiently by joining ("adding") two compounds that each contain double bonds. A team led by Frank Glorius from the University of Münster has now succeeded in performing an unconventional cycloaddition in which a carbon-carbon double bond reacts with a carbon-carbon single bond.

New findings on the internal clock of the fruit fly
Light as a regulator: Team of researchers demonstrates role of transport proteins in the synchronisation of circadian rhythms Most living organisms have an internal clock which, among other things, controls the sleep-wake rhythm. The internal rhythm lasts approximately one day ("circadian"), i.e. about 24 hours, and is regulated by means of various "clock genes".

In search of pure quartz
A small heap of very fine white quartz sand glistens in the palm of Prof. Ralf Hetzel's hand. The grains of sand allow him to look deep into the past. To be precise, the cosmogenic nuclide Beryllium-10 (10Be) does. Such nuclides are produced by cosmic radiation in solid rock.

Acoustic propulsion of nanomachines depends on their orientation
For the first time, physicists simulate the propulsion of freely orientable nanoparticles by travelling ultrasound waves / Study published in -ACS Nano- Microscopically tiny nanomachines which move like submarines with their own propulsion - for example in the human body, where they transport active agents and release them at a target: What sounds like science fiction has, over the past 20 years, become an ever more rapidly growing field of research.

Large majority of citizens trust science
The Corona pandemic has not only impinged on daily life around the world for around two years now - it is increasingly shifting science and research into the focus of public debate. One aspect is the trust people have in the work done by scientists. A team of researchers led by Prof. Rainer Bromme, a psychologist at the University of Münster, now have published a study, which concludes that science has so far passed the pandemic stress test of public trust in science.

First 3D structure of regulator protein revealed
Proteins are indispensable components in living organisms. They are not only "building material" for the body - they also make molecular communication between cells possible, they are needed for nerve impulses to occur, and they control chemical reactions. What is decisive for proteins to function is their three-dimensional structure.

Help for stressed-out cells in a crisis
According to a team of researchers at the University of Münster, mitochondria provide unexpected help for cells in a crisis by respiring away harmful substances. A current study produced by the Institute of Biology and Biotechnology of Plants (IBBP) shows three things: that this mechanism can be triggered by reductive stress, that it protects the folding of certain proteins destined for export, and that the cell's "powerhouse" consequently acts even more flexibly than was previously known.

Researchers investigate advantages of sulphur-containing cathodes
MEET Battery Research Center of the University of Münster starts a new research project in 2022: In the joint project -AReLiS-2-, lithium-sulfur batteries (LSB) and thus a potential successor to today's lithium ion batteries are being investigated. The focus of the research is on sulfur-containing cathodes as well as polymer, solid-state and hybrid electrolytes.

New dual benefit mode of action for a drug candidate to fight Covid-19
A research team led by Prof. Stephan Ludwig, a virologist at the Institute of Virology at the University of Münster, has found a new dual attack mode of action while working on the development of a drug candidate against SARS-CoV-2 infections. This could constitute the basis for a broadly effective drug to fight Covid 19.

Measure eye movements when blinking
Scientists from Westfälische Wilhelms-Universität (WWU) Münster have developed a method to measure the full extent of eye movements during blinks for the first time. The new method uses Magnetic Resonance Imaging (MRI), to take many fast measurements of an entire cross-section of the eye, unlike most common eye tracking that measures only the front of the eyeball.
