On the road to the super-battery
A research team led by the Technical University of Munich (TUM) has taken an in-depth look at the internal workings of batteries during charging and discharging. Their findings may help optimize charging processes. When an electric car is being charged, the charge indicator moves quickly at first, be then much more slowly at the end.

Mucus molecules can thwart fungal infection
Candida albicans is a yeast that colonizes the mucosal surfaces of most healthy humans. Under certain conditions, it can switch to a harmful form and cause infection. Researchers have now identified components of mucus that keep the pathogen from turning destructive, thus laying the foundation for a new class of drugs.

Identifying ’lazy’ and ’industrious’ Cells in Biocatalysis
Breakthrough in tracking biocatalysis by single cells opens up new possibilities in "green chemistry" The transformation of chemical compounds by living cells - so-called whole-cell biocatalysts - is a process that has been known for some time and has led to a wealth of interesting products. This is evident, for example, in traditional processes such as bread baking or beer brewing, where molecules produced by yeast fungi contribute significantly to flavor.

’Fruitcake’ structure observed in organic polymers
Researchers have analysed the properties of an organic polymer with potential applications in flexible electronics and uncovered variations in hardness at the nanoscale, the first time such a fine structure has been observed in this type of material. The field of organic electronics has benefited from the discovery of new semiconducting polymers with molecular backbones that are resilient to twists and bends, meaning they can transport charge even if they are flexed into different shapes.

Multi-functional bandage helps wounds to heal
Researchers at the Technical University of Munich (TUM) have developed a film that not only protects wounds similar to the way a bandage does, but also helps wounds to heal faster, repels bacteria, dampens inflammation, releases active pharmaceutical ingredients in a targeted manner and ultimately dissolves by itself.

Of biosystems and energy-rich chemicals
The German Research Foundation (DFG) announced today that it will fund two Collaborative Research Centres (CRC) for a further four years. A total of about 26 million euros in funding is expected for the projects of these large-scale research associations. This will enable researchers to continue the successful work of CRC 1127 "ChemBioSys" and the Collaborative Research Centre/Transregio (CRC/TRR) 234 "CataLight", which is run jointly with Ulm University and other partners.

How chemicals are trapped in the body by studying polar bear poop
A new University of Toronto study is using polar bear scat to reveal how certain chemical contaminants can become trapped - and build up - inside the body. Polar bears are prone to storing certain contaminants in their bodies because they are at the top of the food chain, have a very fatty diet and have evolved to absorb high amounts of fat.

Biosynthesis of cyanobacterin opens up new class of natural compounds
Researchers in the groups of Prof. Tobias Gulder from TU Dresden and Prof. Tanja Gulder from Leipzig University have succeeded in understanding the biosynthetic mechanisms for the production of the natural product cyanobacterin, which in Nature is produced in small quantities by the cyanobacteria Scytonema hofmanni.

Toward new degradable polymers
Vinyl polymers, commonly referred to as "plastics," are ubiquitous materials. They are extremely interesting for their ease of synthesis and their great diversity in terms of architecture and functionality.

Scientists make plastic more degradable under UV light
Scientists at Bath found that incorporating sugar units into polymers makes them more degradable when exposed to UV light. Many plastics that are labelled as biodegradable are only compostable under industrial conditions, but scientists at the University of Bath have now found a way to make plastics break down using only UV light.

From the packet into your food: what harmful substances are in food packaging?
Salad boxes to go, sealed-tray lasagna and apple juice in PET bottles: we encounter packaged food and drink everywhere. A new database shows which packaging contains harmful substances that can be transferred to its contents. It also includes findings from researchers at the University of Basel, who are investigating plastic molecules that were previously unknown or barely known.

Cooperative molecular networks may have been the spark of life on other planets
According to a UdeM study, life could have emerged on an exoplanet as a result of a type of biochemical cooperation that is more likely to occur in nature than we might think! Darwin's theory of evolution probably isn't the full explanation for the emergence of life. Even in a barren environment conducive to fierce competition, cooperation between molecular networks may have spawned life on Earth and, by extension, elsewhere in the universe.

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.

Machine Learning Gets Smarter To Speed Up Drug Discovery
Researchers at Carnegie Mellon University developed a self-supervised learning framework that leverages the large amounts of unlabeled data that other models can't. Predicting molecular properties quickly and accurately is important to advancing scientific discovery and application in areas ranging from materials science to pharmaceuticals.

Planets of binary stars: Targets in the search for alien life
Planetary systems around stars the size of our sun are obvious targets for astronomers trying to locate extraterrestrial life forms, and nearly every second star in that category is a binary star. New research from Denmark and the University of Michigan indicates that planetary systems are formed in a very different way around binary stars-two stars gravitationally bound to each other-than around single stars such as the sun.

Two thirds of chemicals in food packaging not listed for use
The majority of chemicals found in materials that come into contact with food are not intentionally added during the material's manufacturing process and are not currently listed for use, a new systematic evidence map involving researchers at UCL has revealed. Published today in Critical Reviews in Food Science and Nutrition, researchers found evidence for 2,881 food contact chemicals (FCCs) that may transfer into food or drinks from six types of food contact materials (FCM) groups, including plastics, paper and board, metal, multi-materials, glass and ceramic, and 'other'.

How faulty mRNA is detected and destroyed
Two similar proteins can stand in for each other in the quality control mechanism of defective mRNA. This has redefined the distribution of protein tasks / publication in 'The EMBO Journal'. Scientists led by Professor Dr Niels Gehring at the Institute for Genetics at the University of Cologne have investigated two similar proteins, UPF3A and UPF3B, which are involved in the quality control mechanism 'nonsense-mediated mRNA decay' (NMD).
