How epithelial cells ward off viruses
How epithelial cells ward off viruses
The cytosolic sensor NLRP1 identifies viruses as non-self and triggers inflammatory responses The ability to differentiate between self and potentially harmful non-self is vital for the integrity and survival of organisms. In most organisms, the so-called innate immune system is responsible for the recognition of such intruders.

How nitrogen is transferred by a catalyst
How nitrogen is transferred by a catalyst
Catalysts with a metal-nitrogen bond can transfer nitrogen to organic molecules. In this process short-lived molecular species are formed, whose properties critically determine the course of the reaction and product formation. The key compound in a catalytic nitrogen-atom transfer reaction has now been analysed in detail by chemists at the Universitis of Göttingen Frankfurt and Stuttgart.

Precious metal-free silicone curing
Precious metal-free silicone curing
Sustainable processes could replace precious metals in silicone crosslinking Silicones are tried and tested in the private and professional domains. In many applications, however, expensive precious metals are required as catalysts to transform the liquid intermediate products to durable elastic polymers.

Identifying compound classes through machine learning
Identifying compound classes through machine learning
Bioinformaticians at the University of Jena develop new method for analysing metabolites Everything that lives has metabolites, produces metabolites and consumes metabolites. These molecules arise as intermediate and end products from chemical processes in an organism's metabolism. Therefore, they not only have huge significance for our lives, but they also provide valuable information about the condition of a living being or an environment.

Metal-organic frameworks become flexible
Metal-organic frameworks become flexible
Combined efforts of experiment and simulation pave the way to new applications Materials consisting of inorganic and organic components can combine the best of two worlds: under certain circumstances, the so-called MOFs - short for metal-organic frameworks - are structured in the same order as crystals and are at the same time porous and deformable.

Novel glass materials made from organic and inorganic components
Research team from Jena and Cambridge develops glass materials with novel combinations of properties Linkages between organic and inorganic materials are a common phenomenon in nature, e.g., in the construction of bones and skeletal structures. They often enable combinations of properties that could not be achieved with just one type of material.

Innovative Cell Chemistry Developed for Dual-Ion Battery
Innovative Cell Chemistry Developed for Dual-Ion Battery
A long durability, low costs and high sustainability - the requirements for stationary energy storage systems, for example for wind or solar energy, are high. One promising perspective is the still young dual-ion technology. In a collaboration between Pacific Northwest National Laboratory and the MEET Battery Research Center, scientists developed a new type of dual-ion battery.

Innovative Material Concept for an Improved Silicon Anode
Innovative Material Concept for an Improved Silicon Anode
The lithium-ion battery is currently state of the art, but has not yet realised its full potential. New electrode materials such as silicon instead of pure graphite in the anode offer a significantly increased electrochemical performance. Until now, this has been at the expense of the battery's lifespan.

Smart bottle brushes
Smart bottle brushes
Neutrons make structural changes in molecular brushes visible They look like microscopic bottle brushes: Polymers with a backbone and tufts of side arms. This molecular design gives them unusual abilities: For example, they can bind active agents and release them again when the temperature changes. With the help of neutrons, a research team from the Technical University of Munich (TUM) has now succeeded to unveil the changes in the internal structure in course of the process.

Molecular water discovered on the moon by the SOFIA flying observatory
Molecular water discovered on the moon by the SOFIA flying observatory
For the first time, the SOFIA (Stratospheric Observatory for Infrared Astronomy) flying observatory has provided direct and unambiguous evidence of water molecules on the moon beyond the permanent shadow at the poles. The infrared observatory, which is owned jointly by the US space agency NASA and the German Aerospace Center (DLR) was able to detect the molecules in the moon's southern hemisphere using the FORCAST (Faint Object InfraRed CAmera for the SOFIA-Telescope) instrument.

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.
