Food supplements are available in a lot of places - in drugstores, health food shops, pharmacies and on the Internet - and the market is booming. Many of these products contain plant extracts whose ingredients are supposed to have healthy benefits - provided they do actually contain what they claim. Because nowhere near all of these so-called botanicals deliver what they promise.

Light is used for various purposes in nowadays applications. For example, data can be transmitted with light and nanoscopic structures can be created by light. To enable such applications, light must be structured. To do this, its properties - intensity (brightness), phase (position in oscillation-cycle) and polarization (direction of the oscillation) - are "tailored".

The bodies of animals and humans are innervated by a network of nerve cells which are connected through long extensions. The nerve cells use these so-called axons and dendrites to communicate with one another. During early development, nerve cells grow a large number of axons and dendrites. To make the connections specific, redundant extensions are removed at a later stage in a process called "pruning".

Dr. Francesco Catania is head of the working group "Evolutionary Cell Biology" at the Institute for Evolution and Biodiversity at the University of Münster. His group uses bioinformatics and experimental approaches to investigate how the interaction of cells and organisms with their environment leads to the emergence of new properties.

Titin is a "titanically large" protein - the largest in the human body - which enables elastic movements of our muscles, including the heart. Mutations in the titin gene ( TTN ) that impair this function are the most frequent cause of a heart muscle disease known as dilated cardiomyopathy (DCM), which is characterized by a weak pump function.

The neurons, located in the brain are interconnected in a complex pattern and establish special communication points, the synapses. All neurons require a constant environment in order to function reliably. To ensure this, the brain is surrounded by the so-called blood-brain barrier. It ensures, for example, that the nutrient balance always remains the same and that harmful influences do not reach the neurons.

Planetologists from Münster investigate origin of heavy bombardment of the Moon 3.9 billion years ago / Publication in "Science Advances" The lunar surface is covered by numerous craters that date back to the impacts of asteroids. Age determinations on lunar rocks formed during these impacts show a surprising clustering at ages of about 3.9 billion years before present, or about 500 million years after the Moon was formed.

Researchers develop imaging methods to examine bodily processes from the individual building blocks to the whole system / Proof-of-principle study on SNAP-tag technology published in the journal "Chemical Communications" Video in English, subtitles available in English and German. Processes and structures within the body that are normally hidden from the eye can be made visible through medical imaging.

A comprehensive analysis of white blood cells in the tissue surrounding the brain / Study published in the journal "Nature Neuroscience" The brain holds numerous unsolved medical mysteries. Only a few years ago it was discovered that the outer layer of the meninges is interlaced with lymphatic vessels.

"You can't see the wood for the trees" is a phrase which we certainly don't associate immediately with the medical examination and analysis of testicles. But in a certain way it applies here, too: testicles consist of many different types of cells, and up to now this complex quality prevented these types from being isolated and then analysed.

Nanocontainers made of biological materials use natural processes to enter cells and release their cargo / Study published in the journal "Advanced Science" Nanocontainers can transport substances into cells where they can then take effect. This is the method used in, for example, the mRNA vaccines currently being employed against Covid-19 as well as certain cancer drugs.

Researchers investigate which material properties support vessel formation / Study published in the journal "Nature Communications" Using lab-created tissue to heal or replace damaged organs is one of the great visions for the future of medicine. Synthetic materials could be suitable as scaffolding for tissue because, unlike natural tissues, they remain stable in the organism long enough for the body to form new natural structures.

Scientists at the University of Münster provide new insights into interactions between platelets and white blood cells in mice / Study published in the Journal of Experimental Medicine Treating patients with acute respiratory failure is a constant challenge in intensive care medicine. In most cases, the underlying cause is lung inflammation triggered by a bacterial infection or - more rarely, despite being frequently observed at present due to the corona pandemic - a viral infection.

Some species of ants make life easier for themselves: they live in the colonies of other ant species, exploiting their hosts' resources. This form of social parasitism has evolved several times independently in ants. An international team of researchers headed by biologist Dr. Lukas Schrader at the University of Münster has now shown that these social parasites have lost some parts of their genomes.

Tuberous Sclerosis Complex (TSC) affects between one and two of every 10,000 new-born babies. This genetic disease leads to the formation of benign tumours which can massively impair the proper functioning of vital organs such as the kidneys, the liver and the brain. The disease affects different patients to varying degrees and is triggered by mutations in one of two genes, the TSC1 or TSC2 gene.

Cancer, Alzheimer's, diabetes or cardiovascular diseases are what are known as non-communicable diseases, which are responsible for the majority of deaths worldwide - in Germany, an estimated 91 percent of all deaths are the result of these diseases, and it is a rising trend. Epidemiologists have been studying the development and distribution of these epidemiological diseases, as well as the measures to combat them and what their social consequences are.

High carbon dioxide concentrations are required to allow the central metabolic pathway to run "backwards" / publication in "Nature" The citric acid cycle is an important metabolic pathway that enables living organisms to generate energy by degrading organic compounds into carbon dioxide (CO₂). The first step in the cycle is usually performed by the enzyme citrate synthase, which builds citrate.

Insect decline is one of the greatest challenges facing our society. As a result of the destruction of many natural habitats, bees, bumblebees, butterflies, beetles and the like find less and less food. As a consequence, they are barely able to fulfil their role as pollinators of wild and cultivated plants.

Materials such as gallium arsenide are extremely important for the production of electronic devices. As supplies of it are limited, or they can present health and environmental hazards, specialists are looking for alternative materials. So-called conjugated polymers are candidates. These organic macromolecules have semi-conductor properties, i.e. they can conduct electricity under certain conditions.

A major goal of organic and medicinal chemistry in recent decades has been the rapid synthesis of three-dimensional molecules for the development of new drugs. These drug candidates exhibit a variety of improved properties compared to predominantly flat molecular structures, which are reflected in clinical trials by higher efficacy and success rates.
