Scientists are closer to finding out how. Pyrrolizidine alkaloids are as bitter and toxic as they are hard to pronounce. They’re produced by several different types of plants and are among the leading causes of accidental death in cattle. Plants that contain these alkaloids have made it very clear they don’t want to be consumed, but that hasn’t deterred bella moths (Utetheisa ornatrix). These day-flying moths exclusively eat the alkaloid-laden leaves and seeds of rattlebox plants. They then use the…
FAU chemists conduct research into novel approach of using an organic module for storing solar energy. Until now, the generation and storage of electricity from solar energy has been dependent on various devices, leading to conversion losses. That may change soon: chemists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and other research institutes in Germany, Australia, the United Kingdom, Italy, Sweden and the USA are conducting research into a hydrocarbon molecule that can either convert sunlight into electricity or save the energy for…
Scientists at the NMI have unraveled the mode of action of collagen crosslinking in the treatment of corneal defects and the results open up new opportunities for the use of collagen in medicine. Collagen has been used in ophthalmology since the 1990s, particularly in the treatment of corneal defects. However, why and how this technique works was only known in theory. Researchers at the NMI Natural and Medical Sciences Institute in Reutlingen led by Lu Fan have found the necessary…
… promotes functional nerve regeneration. Researchers from the University of Cologne have found a new use for Cnicin, a substance produced in blessed thistle. Clinical studies are being planned / publication in ‘Phytomedicine’. Blessed thistle (Cnicus benedictus) is a plant in the family Asteraceae and also grows in our climate. For centuries, it has been used as a medicinal herb as an extract or tea, e.g. to aid the digestive system. Researchers at the Center for Pharmacology of University Hospital…
An international team at the world’s largest X-ray laser European XFEL at Schenefeld near Hamburg has scrutinised the properties of an important nanogel that is often used in medicine to release drugs in a targeted and controlled manner at the desired location in a patient’s body. The team now published the results in the journal Science Advances. An international team led by Felix Lehmkühler from Deutsches Elektronen-Synchrotron DESY in Hamburg has investigated the temperature induced swelling and collapsing of the…
A research team led by Dr Serge Krasnokutski from the Astrophysics Laboratory at the Max Planck Institute for Astronomy at the University of Jena had already demonstrated that simple peptides can form on cosmic dust particles. However, it was previously assumed that this would not be possible if molecular ice, which covers the dust particle, contains water – which is usually the case. Now, the team, in collaboration with the University of Poitiers, France, has discovered that the presence of…
Charité study in Science decodes wiring of the human neocortex. Contrary to previous assumptions, nerve cells in the human neocortex are wired differently than in mice. Those are the findings of a new study conducted by Charité – Universitätsmedizin Berlin and published in the journal Science.* The study found that human neurons communicate in one direction, while in mice, signals tend to flow in loops. This increases the efficiency and capacity of the human brain to process information. These discoveries…
… as efficient piezocatalyst for synthesis of H2O2 from pure water. As an important chemical raw material, hydrogen peroxide (H2O2) is widely applied in various aspects of industry and life. The industrial anthraquinone method for H2O2 production has the serious flaws, such as high pollution and energy consumption. By using ubiquitous mechanical energy, piezocatalytic H2O2 evolution has been proven as a promising strategy, but its progress is hindered by unsatisfied energy conversion efficiency. Bi4O5Br2 is regarded as a highly attractive…
Microbial reduction reduces mobility of uranium compounds. When designing repositories for high-level radioactive waste in deep geological layers, various factors must be carefully considered to ensure their long-term safety. Among other things, natural communities of microorganisms can influence the behavior of the waste, especially when it comes into contact with water. The microorganisms interact with released radionuclides and influence their mobility. Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have taken a closer look at a microorganism that occurs in the vicinity…
When babies learn to talk or birds learn to sing, the same principle applies: listen and then imitate. This is how the first babble becomes the first word or vocalization. Male zebra finch chicks initially memorize the song of an adult bird. Later, they refine their own vocalization until they resemble the learned song. Researchers at the MPI for Biological Intelligence have now shown that the first vocalizations of zebra finches play a role even before they practice to sing…
Researchers turn metal waste into catalyst for hydrogen. Scientists have found a way to transform metal waste into a highly efficient catalyst to make hydrogen from water, a discovery that could make hydrogen production more sustainable. A team of researchers from the University of Nottingham’s School of Chemistry and Faculty of Engineering have found that the surface of swarf, a byproduct of the metal machining industry, is textured with tiny steps and grooves on a nanoscale level. These textures can…
In their natural environment, wild bees are exposed to various pesticides that can have a potentially toxic effect. A study by the University of Würzburg has now shown that bumblebees are relatively resistant to these products. Bumblebees appear to be quite resistant to common pesticides. This is shown by a new study, the results of which have now been published by scientists from Julius-Maximilians-Universität Würzburg (JMU) in the journal Environment International. The team from the University’s Biocenter divided a bumblebee…
Research team at the University of Freiburg discovers previously unknown gene that indirectly promotes photosynthesis. Cyanobacteria – also called blue-green algae – are known as the “plants of the ocean” because they carry out photosynthesis on a gigantic scale, produce oxygen and extract the greenhouse gas CO2 from the environment. However, to do this they need additional nutrients such as nitrogen. A team headed by biologist Prof. Dr Wolfgang R. Hess, Professor of Genetics at the University of Freiburg, has…
Genetic mechanisms uncovered… Boron deficiency has a devastating effect on oilseed rape and related plants. However, little is known about the underlying genetic mechanisms. A study shows that the response to persistent or short-term acute boron deficiency is similar to that to pests and infections. The results lay the foundation for breeding plants that can better cope with boron deficiency and for avoiding related yield losses. Oilseed rape reacts to boron deficiency during flowering in a similar way as to…
Ferdi Schüth and his team at the Max Planck Institut für Kohlenforschung in Mülheim/Germany have been studying the phenomena of mechanochemistry for several years. But what actually happens at the molecular level when two balls collide in a mill? The Mülheim scientists are now receiving around 2.5 million euros in funding from the European Union for their research. The chemical industry is facing major challenges that require new solutions. For example: How can chemicals be produced more cheaply, simply and…
