"Novel first-in-class intra-nasally applicable safe recombinant "vir4vac" RNA vaccines constitute a very safe and efficacious way of preventing serious infections of respiratory corona and paramyxoviruses as well as other respiratory viruses.“

The development of the cation channel channelrhodopsin-2 (ChR2) from Chlamydomonas reinhardtii by Prof. Ernst Bamberg and his colleagues and its application to light-induced modulation of neurons paved the way for the field of optogenetics.
Over time the light-gated cation channel channelrhodopsin-2 (ChR2) has become an indispensable tool in neuroscience. Based on the pioneering work on ChR2 new variants have emerged, differing in their spectrum of light absorption, their kinetic ...

Prof. Klaus-Richard Pörschke and co-workers from the MPI for Coal Research developed a highly hydrophobic perfluoroaryl borate (FAB) ligand for trapping the radioative 134/137 Cs isotopes with 100% specificity. The novel approach could improve the decontamination of humans compared to the administration of so called insouble Prussian blue currently in use.

Prof. Klaus-Richard Pörschke and co-workers at the MPI for Coal Research developed a novel cyclic process for the quantitative extraction of cesium with 100% selectivity from any given aqueous or acidic solution, irrespective of the other components.

The cellular identity of mature cells that are confined in a specialized genetic expression profile can be overcome by introducing just a few genes that encode for so-called reprogramming factors [1]. By means of this intervention, also known as reprogramming, the cells then become pluripotent and represent induced pluripotent stem cells (iPS cells) [1]. Nowadays, numerous new cell culture models have been established based on reprogramming protocols that yield iPS cells. Such cell culture models ...

Precise genome editing demands for homology-directed repair (HDR) by aiming to introduce a new double stranded DNA substituting for a homologous sequence but partially defect one. This substrate dependent reaction does compete with direct non-homologous end joining (NHEJ) of the double strand breaks. NHEJ is error-prone and is therefor mainly used for gene inactivation.
The rate of NHEJ is directly limiting the rate of HDR. For this reason HDR in vitro does occur on a very low level only and ...

The CRISPR-Cas system is a powerful tool for site-specific genome editing. It allows for the inactivation or substitution of entire genes. However, most hereditary diseases in humans are caused by single point mutations, the correction of which requires only subtle changes to the DNA. Recently, base editors (BEs) were developed that allow the introduction of selective nucleotide substitutions. A Cas9 enzyme is fused to a nucleobase deaminase catalysing C-to-T mutations (by C-to-U deamination) ...

The LITESEC-T3SS (Light-induced translocation of effectors through sequestration of endogenous components of the T3SS) system represents a novel, fast, specific, and reversible method to control protein secretion into eukaryotic cells, enabling various medicinal and biotechnological applications, such as targeted drug delivery for tumor therapy.

We offer a new family of cationic ligands, namely N-alkyl/aryl pyridiniophosphines. The ligands can be synthesized through a short, scalable, and highly modular route.

Evaluation of their electronic properties evidenced weak σ-donor and quite strong π-acceptor character when used as ancillary ligands.

We present an extremely sensitive, reliable and fast novel Lysine deacetylase (KDAC) assay, which can be performed in a continuous format. This novel KDAC assay is based on Firefly luciferase harboring an acetylation on an essential active site lysine, incorporated by genetic code expansion.

We furthermore offer a bacterial selection system that can help engineer KDACs. The selection system uses a reporter enzyme inactivated by lysine modifications at an essential active site residue, thereby ...

Antiviral therapy against retroviruses and alphaviruses using tRNA^Leu(UUA) overexpression

A computer-implemented method that allows calculating concentration ranges of components within complex networks of biochemical reactions.

The ability of hypervalent iodine compounds to act as electrophilic group-transfer reagents has been extensively exploited during the last several years in a variety of synthetically useful transformations
like cyanations and alkynylations. Now it was found, that novel imidazolium sulfuranes, which are isolobal to I(III) species and also depict the key threecenter four-electron bond motive, can be used as an alternative platform for the development of new electrophilic group-transfer reagents.

Imidazolium ...

An apparatus and method allowing high throughput collection of X-ray diffraction data at room temperature.

We offer the new composite nanomaterial for sodium ion battery cathodes. These carbon-coated nanosized Na₃V₂(PO₄)₃ particles embedded in a highly effective mixed conducting porous carbon matrix can be easily prepared by means of facile soft-chemistry based preparation method with a post heat treatment procedure. The resulting cathodes can be charged and discharged in 6 s with high current density of 22 A/g, deliver the specific capacity of 44 mAh/g and ...
