How "protein factories" mature
Ribosomes are small "factories" in which proteins are assembled according to genetic construction plans. The maturation of ribosomes, of which every human cell contains up to a million, is a complicated, multi-phase process. Now, with the aid of cryo-electron microscopy, scientists from Heidelberg University and Ludwig-Maximilians-Universität München have been able to clarify an important step in ribosomal formation.

Molecular swarm rearranges surface structures atom by atom: New study
Molecular swarm rearranges surface structures atom by atom: New study
Much like a zipper, carbene molecules cooperate on a gold surface to join two rows of atoms into one row, resulting - step by step - in a new surface structure. The surface of metals plays a key role in many technologically relevant areas, such as catalysis, sensor technology and battery research. For example, the large-scale production of many chemical compounds takes place on metal surfaces, whose atomic structure determines if and how molecules react with one another.

Can organic plant protection products damage crops?
Researchers at Göttingen University discover new disease affecting maize Protecting crops against pests and diseases is essential to ensure a secure food supply. Around 95 percent of food comes from conventional agriculture, which uses chemical pesticides to keep crops healthy. Increasingly, however, organic pesticides are also being sought as an alternative.

Newly discovered mechanism regulates myocardial distensibility
Immunofluorescence staining of the muscle tissue of a chronically diseased human heart under the confocal microscope. Two proteins in the sarcomeres, which give the tissue the characteristic striation pattern, were marked with antibodies and visualized by different fluorophore-conjugated antibodies: titin appears red and actinin green; the nuclei were stained blue.

New Analytical Methods for Longer-Lasting Lithium-ion Batteries
New Analytical Methods for Longer-Lasting Lithium-ion Batteries
How can the lithium-ion battery (LIB) be further improved? To answer this question, MEET scientists around Lenard Hanf developed new methods for capillary electrophoresis. For the first time, this enables a detailed analysis of the transition metal dissolution from LIB cathode materials or the current collector - such as manganese or copper.

Battery Research Centre: new international research school opened
Longer ranges for electric vehicles and the effective storage of electricity from renewable energies - these are research topics for the future which PhD students in Münster will be working on in a new international Graduate School. The research centre for "Battery Chemistry, Characterization, Analysis, Recycling and Application" (BACCARA for short) was officially opened on August 5 at the MEET Battery Research Centre at the University of Münster.

Researchers solve a long-standing problem in organic chemistry
Chemists at the University of Münster develop a bioinspired strategy for the controlled synthesis of polyenes / Study published in "Science" They occur in nature, are reactive and play a role in many biological processes: polyenes. It is no wonder that chemists have for a long time been interested in efficiently constructing these compounds - not least in order to be able to use them for future biomedical applications.

New method enables a view inside batteries
The Solid Electrolyte Interphase (SEI) inside both lithium-ion and lithium metal batteries is indispensable for successful battery cell operation and at the same time an analytical challenge. Up to now, its analysis has only been possible to a limited extent; knowledge about formation, composition, growth or reactions is incomplete.

Proteins Analysed, Volunteers Sought
A research team led by zoologist Dr Amy MacLeod has been using drones to count marine lizards on the Galapagos Islands. The aim of the Leipzig University project is to determine the colony sizes of this vulnerable species and, with the help of volunteers, to precisely locate them - in order to ultimately be able to better protect the iguanas.

Rock 'n' Control
Rock ’n’ Control
Göttingen Physicists use oscillations of atoms to control a phase transition The goal of -Femtochemistry- is to film and control chemical reactions with short flashes of light. Using consecutive laser pulses, atomic bonds can be excited precisely and broken as desired. So far, this has been demonstrated for selected molecules.

Enzymes as double agents: new mechanism discovered in protein modification
Enzymes as double agents: new mechanism discovered in protein modification
Proteins are the workers in a cell and, as the “basic element of life?, are responsible for the most widely varying metabolic processes. In plants, for example, they take on an important function in photosynthesis. In order to be able to work purposefully, proteins change their chemical form after they have been produced in a cell - for example, through protein acetylation, when an acetyl group is transferred to the protein.

The molecular gas in galaxies is organised into a hierarchy of structures. It moves along filament-like orbits to centres of gas and dust where it is compressed into stars and planets. To better understand this, an international team of astronomers led by Dr Jonathan Henshaw from the Max Planck Institute for Astronomy and Dr Diederik Kruijssen from the Center for Astronomy at Heidelberg University examined gas movements on various size scales.

How do bacteria build up natural products?
How do bacteria build up natural products?
X-ray structure analysis gives detailed insights into molecular factory The active agents of many drugs are natural products, so called because often only microorganisms are able to produce the complex structures. Similar to the production line in a factory, large enzyme complexes put these active agent molecules together.

New insights into lithium metal technology
New insights into lithium metal technology
It is one of the key technologies for high-performance batteries of the future: the lithium metal battery (LMB). Designed for instance as solid-state battery with polymer electrolyte, it promises a significantly higher energy density than the currently common lithium-ion battery (LIB). However, it is not yet fully developed for the final commercial breakthrough and is therefore currently used by only a few pilot projects.

Chanterelle mushrooms as a taste enhancer
Chanterelle mushrooms as a taste enhancer
New method for quality control of chanterelle mushrooms Chanterelles give savoury dishes a rich body and a unique complex flavour. Experts refer to this as the kokumi effect. A research team from the Technical University of Munich (TUM) and the Leibniz-Institute for Food Systems Biology recently developed the first method to clearly quantify chanterelle-specific key substances that contribute to this effect.

Researchers create a photographic film of a molecular switch
Molecular switches - they are the molecular counterparts of electrical switches and play an important role in many processes in nature. Such molecules can reversibly interconvert between two or more states and thereby control molecular processes. In living organisms, for example, they play a role in muscle contraction but also our visual perception is based on the dynamics of a molecular switch in the eye.

Triggered by light, a novel way to switch on an enzyme: Biotechnology
Enzymes: they are the central drivers for biochemical metabolic processes in every living cell, enabling reactions to take place efficiently. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. A topic that is currently being widely discussed is photoinduced catalysis, in which researchers harness the ability of nature to start biochemical reactions with the aid of light.

In addition to high purchase costs and the still underdeveloped charging infrastructure, the limited range is one of the biggest obstacles to switching to electric vehicles. Industry and science are therefore working intensively on developing batteries with a higher energy density and making them suitable for series production.
